I have a post type which I want to add some taxonomy values (tags)
Example Post Type One
1. **City**: London, Paris
2. **Color**: Red, Yellow
3. **Language**:
In the example above, Language doesn't have any value, therefore, I want to hide it.
I have this code:
```
<?php
$lang= get_terms( 'lang' );
if ( !empty( $lang)) {
echo '<li><strong>Language:</strong>';
the_terms( $post->ID, 'lang', ' ', ', ' );
echo '</li>';
}
?>
```
But **Language** will still appear even though I don't add any tags on it.
|
[`get_terms()`](https://developer.wordpress.org/reference/functions/get_terms/) return all the terms in the taxonomy regardless of the current post.
So if current post does not have **lang** terms still this condition `if ( !empty( $lang))` will be `true` thus it will display the text **Language**.
Use [`get_the_term_list`](https://codex.wordpress.org/Function_Reference/get_the_term_list) instead of `the_terms` which return the terms list instead of printing, so output can be used for both purpose.
Example:-
```
$lang = get_the_term_list( get_the_ID(), 'lang', ' ', ', ' );
if ( !empty( $lang)) {
echo '<li><strong>Language:</strong>' . $lang . '</li>';
}
```

The `enfoce_gzip` constant, and the other in the same group in your config, actually refer to how wordpress should serve admin side related JS and CSS, and it seems like you are interested in the front end.
Setting gzip compression is something that you should do in your server configuration level (several options depending on the server, but for apache you will probably do it in the .htaccess file), the reason is that most files being served - CSS, JS, images, do not pass though wordpress code at all and therefor wordpress can not have any influence on how they are being served.

<p>I need to replicate that short code a few times but I can not figure out where the four digit number referencing the image comes from. </p>
<p>I tried changing the <code>7004</code> to a image name and even tried the absolute path to the image. Nothing shows up when I do this not even a broken image. </p>
<p>What is that number and how can I add a different image to this short code?</p>

I am working on a wordpress site that has this short code,
```
[vc_single_image image="7004" css_animation="right-to-left" border_color="grey" img_link_target="_self" img_size="300px"]
```
I need to replicate that short code a few times but I can not figure out where the four digit number referencing the image comes from.
I tried changing the `7004` to a image name and even tried the absolute path to the image. Nothing shows up when I do this not even a broken image.
What is that number and how can I add a different image to this short code?
|
It's not easy to trace trough the code behind `[vc_single_image]`, because for start it uses the [`extract`](http://php.net/manual/en/function.extract.php), that's not recommended in WordPress or PHP in general.
The `image` attribute value is stripped for non-integers into the `$img_id` variable.
With your setup, there's a call to `wpb_getImageBySize( array( 'attach_id' => $img_id, ... )`, that seems to be a wrapper that includes:
```
wp_get_attachment_image_src( $attach_id, 'large' );
```
So this `image` attribute is the image attachment ID (integer), just as Nathan Powell mentioned.
If we turn on the *backend editor* for the visual composer:
[](https://i.stack.imgur.com/dTKhx.jpg)
with the code you posted, then we should get this kind of view:
[](https://i.stack.imgur.com/pcFHb.jpg)
Click on the green pen and we should get the single image settings:
[](https://i.stack.imgur.com/nKkVX.jpg)
there it's easy to select the image attachment directly from the media library.
If we don't wan't the visual setup, we can get the image attachment ID from various links in the Media library. For example when we edit an attachment, the url is:
```
/wp-admin/post.php?post=7004&action=edit
```
or when we view the attachment details, the url is:
```
/wp-admin/upload.php?item=7004
```
Hope it helps!

<p>I've blocked access to xmlrcp, and removed most everything that is generated in <code>wp_head</code>. However, I'm still getting notifications in the admin about comments being posted on posts even when there is no form on that page. How is this possible?</p>
<p><strong>I'm thinking that this below would work:</strong></p>
<pre><code>// Remove comment support
add_action( 'init', function() {
remove_post_type_support( 'page', 'comments' );
remove_post_type_support( 'post', 'comments' );
});
// Close open comments
add_filter( 'comments_open', function( $open, $post_id ) {
$post = get_post( $post_id );
if ( 'page' == $post->post_type || 'post' == $post->post_type )
$open = false;
return $open;
}, 10, 2 );
</code></pre>
<p>However, whether the above works or not, I'm still wondering how someone/ or a spam bot is able to post a comment when there is no form or anything on the page.</p>

The visual representation of a comment form (or lack of it) do not have any impact on the ability to receive comments, and spammers usually don't care at all what is in your form. Wordpress have a well publicized end point to which all comments are being sent (and while I don't remember the detail off the top of my head right now) and spammers can post to that endpoint with enough details to make a proper comment, without even loading the post to which they comment to.
One of the easy antispam steps against lazy spammers is to add an hidden field to the comment form and discard every comment which is submitted without it.

<p>I'm creating my own theme and I'm looking to add a featured image option by adding:</p>
<pre><code>add_theme_support( $feature, $arguments );
</code></pre>
<p>Into the <code>functions.php</code> file. When I do this I get this error:</p>
<pre><code>add_theme_support( 'post-thumbnails' ); Warning: Cannot modify header information - headers already sent by (output started at /wp-content/themes/Precise/functions.php:3) in /wp-includes/pluggable.php on line 1228

I'm creating my own theme and I'm looking to add a featured image option by adding:
```
add_theme_support( $feature, $arguments );
```
Into the `functions.php` file. When I do this I get this error:
```
add_theme_support( 'post-thumbnails' ); Warning: Cannot modify header information - headers already sent by (output started at /wp-content/themes/Precise/functions.php:3) in /wp-includes/pluggable.php on line 1228
```
How can I fix this?
|
As user [/u/majick](https://wordpress.stackexchange.com/users/76440/majick) suggests in the comments below: the better option may be [`after_setup_theme`](https://codex.wordpress.org/Plugin_API/Action_Reference/after_setup_theme) which looks like this:
```
function theme_setup() {
add_theme_support( 'post-thumbnails' );
}
add_action( 'after_setup_theme', 'theme_setup' );
```
---
Another options is to use `init`.
```
function theme_init() {
add_theme_support( 'post-thumbnails' );
}
add_action( 'init', 'theme_init' );
```
The [`init`](https://codex.wordpress.org/Plugin_API/Action_Reference/init) hook explicitly states:
>
> Fires after WordPress has finished loading **but before any headers are sent**.

<p>I have created the code to loop through the product list and display the price</p>

<p><code>get_price_html()</code> works perfectly and display the price like this:</p>

`get_price_html()` works perfectly and display the price like this:

From: $ 621 $ 559

However , I would like to get the price separately
I can get the sales price with
```
$product->get_display_price()
```
The problem is, I can not get the original price,
I tried `$product->get_regular_price()` , that return nothing
And I tried `$product->get_display_price( $product->get_regular_price() )`, that return the sales price
So how to get the original price ? Thanks a lot.

I'm pretty sure that the problem is, that the `WP_Query` returns *post objects*, which are not identical to Woocommerces *product objects*. While you are trying to get the product data by getting the according global, that won't work, especially because the query you are performing does nothing to that global. Now what I probably would do is, firstly, performing the query with the `fields` parameter set to `ids`. Secondly, when looping over the returned array of ids, I would suggest you get the *product object* with `wc_get_product()`, which should give you all the information you need.

<p>I'm trying to implement a custom RSS feed that is formatted for podcasting and pulls in the audio file from an Advanced Custom Field. Basically I've been working off of the example provided here: <a href="https://css-tricks.com/roll-simple-wordpress-podcast-plugin/" rel="nofollow">https://css-tricks.com/roll-simple-wordpress-podcast-plugin/</a></p>
<p>My plugin looks like this:</p>
<pre><code>// add a custom RSS feed
function podcast_rss(){
add_feed('podcast', 'run_podcast_rss');
}
add_action('init', 'podcast_rss');
function run_podcast_rss(){
require_once( dirname( __FILE__ ) . '/feed-template.php' );
}
</code></pre>
<p>This seems pretty straightforward, but when I navigate in my browser to my new feed URL (<a href="http://example.com/feed/podcast/" rel="nofollow">http://example.com/feed/podcast/</a>) The browser tries to download a file. In Google Chrome, the console shows</p>
<pre><code>Resource interpreted as Document but transferred with MIME type application/octet-stream: "http://example.com/feed/podcast/".
</code></pre>
<p>While in Firefox, when it attempts to download the file, it tells me it's a DMS file.</p>
<p>I've tried clearing cache, checking for errors in the code, checking .htaccess for odd settings, setting headers; nothing seems to have an effect. In fact, I can comment out the require_once line and simply try to echo plain text. It still forces a download. I've put this on a different server and it behaves the same.</p>
<p>I have a feeling it's something simple but I'm out of ideas. Any help?</p>

You need to explicitly set the Content Type, otherwise WordPress defaults to octet-stream for unknown feeds.
```
function run_podcast_rss(){
header( 'Content-Type: application/rss+xml; charset=' . get_option( 'blog_charset' ), true );
require_once( dirname( __FILE__ ) . '/feed-template.php' );

You need to explicitly set the Content Type, otherwise WordPress defaults to octet-stream for unknown feeds.
```
function run_podcast_rss(){
header( 'Content-Type: application/rss+xml; charset=' . get_option( 'blog_charset' ), true );
require_once( dirname( __FILE__ ) . '/feed-template.php' );
}

I've built a custom query for geolocation searches. I'm saving lat and lng within each custom post type as a meta value. My query extension returns results successfully when lat and lng are the only search variables.
Problem: I would like to also add tax\_queries to my query to further select posts
**Class to extend query:**
```
class WP_Query_Geo extends WP_Query {
function __construct( $args = array() ) {
if(!empty($args['lat'])) {
$this->lat = $args['lat'];
$this->lng = $args['lng'];
$this->distance = $args['distance'];
$this->lat_meta_name = $args[ 'lat_meta_name' ];
$this->lng_meta_name = $args[ 'lng_meta_name' ];
$this->orderby = $args[ 'orderby' ];
$this->unit_of_measure = 3959;
add_filter('posts_fields', array($this, 'posts_fields'));
add_filter('posts_join', array($this, 'posts_join'));
add_filter('posts_where', array($this, 'posts_where'));
add_filter('posts_orderby', array($this, 'posts_orderby'));
}
parent::query($args);
remove_filter('posts_fields', array($this, 'posts_fields'));
remove_filter('posts_join', array($this, 'posts_join'));
remove_filter('posts_where', array($this, 'posts_where'));
remove_filter('posts_orderby', array($this, 'posts_orderby'));
}
function posts_fields($fields) {
global $wpdb;
$fields = $wpdb->prepare(" $wpdb->posts.*, pm1.meta_value, pm2.meta_value,
ACOS(SIN(RADIANS(%f))*SIN(RADIANS(pm1.meta_value))+COS(RADIANS(%f))*COS(RADIANS(pm1.meta_value))*COS(RADIANS(pm2.meta_value)-RADIANS(%f))) * %d AS distance ", $this->lat, $this->lat, $this->lng, $this->unit_of_measure);
return $fields;
}
function posts_join($join) {
global $wpdb;
$join .= " INNER JOIN $wpdb->postmeta pm1 ON ($wpdb->posts.id = pm1.post_id AND pm1.meta_key = '".$this->lat_meta_name."')";
$join .= " INNER JOIN $wpdb->postmeta pm2 ON ($wpdb->posts.id = pm2.post_id AND pm2.meta_key = '".$this->lng_meta_name."')";
return $join;
}
function posts_where($where) {
global $wpdb;
$where .= $wpdb->prepare(" HAVING distance < %d ", $this->distance);
return $where;
}
function posts_orderby($orderby) {
if($this->orderby == 'distance') $orderby = " distance ASC, " . $orderby;
return $orderby;
}
}
```
**Query:**
```
$args = array(
'post_type' => 'custom',
'posts_per_page' => 15,
'post_status' => 'publish',
'paged' => $page,
'orderby' => 'distance',
'lat' => $lat,
'lng' => $lng,
'distance' => $distance,
);
$the_query = new WP_Query_Geo( $args );
```
The above works. As soon as I add a tax query I receive an error.
**Example tax query:**
```
$tax_query_args = array( 'relation' => 'AND' );
$tax_to_push = array(
'taxonomy' => 'custom-tax',
'field' => 'id',
'terms' => array(1,2,3),
'operator' => 'IN'
);
array_push($tax_query_args, $tax_to_push);
$args['tax_query'] = $tax_query_args;
```
**Error Message:**
```

You need to explicitly set the Content Type, otherwise WordPress defaults to octet-stream for unknown feeds.
```
function run_podcast_rss(){
header( 'Content-Type: application/rss+xml; charset=' . get_option( 'blog_charset' ), true );
require_once( dirname( __FILE__ ) . '/feed-template.php' );
}
```

<p>I wish to change/remove parts of the automatic post class function that's built in to wordpress, lets say when i make a post, the html code generated looks like this:</p>
<pre><code><div id="post-106" class="contentmain fullwidth post-106 post type-post status-publish format-standard has-post-thumbnail hentry category-test category-test2 category-test3 category-test4 tag-testingtags1 tag-testingtags2 tag-testingtags3">
</code></pre>
<p>I wish to remove tags from being in this auto generated code (the tag-testingtags1,2,3), i cannot find which function in wordpress generates the code, anyone care to point me in the right direction? If it is a core file is there a simple way to exclude tags from being inserted into the code using some kind of filter hook in functions.php so i don't have to modify wp core files?</p>

Ok I found the answer that no one has on the net I been looking for days now.
Here is how I was able to do it. Hope this helps someone out there
```
// This is getting the image / url
$feature1 = get_theme_mod('feature_image_1');
// This is getting the post id
$feature1_id = attachment_url_to_postid($feature1);
// This is getting the alt text from the image that is set in the media area
$image1_alt = get_post_meta( $feature1_id, '_wp_attachment_image_alt', true );
```
Markup
```
<a href="<?php echo $feature1_url; ?>"><img class="img-responsive center-block" src="<?php echo $feature1; ?>" alt="<?php echo $image1_alt; ?>"></a>

<p>In some cases it might be useful to use multiple post & page parameters in your <code>WP_Query</code> object. In my case, I would like to display children of a parent page including the parent page itself.</p>
<p>Visualization of what I want to achieve. Imagine the following pages hierarchically sorted as following:</p>
<ul>
<li>page A</li>
<li><strong>page B</strong>
<ul>
<li><strong>Child page A</strong></li>
<li><strong>Child page B</strong></li>
<li><strong>Child page C</strong></li>
</ul></li>
<li>page C</li>
</ul>
<p>The <strong>bold list items</strong> are the posts/pages I want to retrieve.</p>
<p>My first thoughts go out using these two parameters for <code>WP_Query</code>:</p>
<pre><code>$args = array(
'post_id' => $parent->ID,
'post_parent' => $parent->ID,
);
</code></pre>
<p>Unfortunately, here it will only use one parameter. With the <code>$args</code> above (correct me if I'm wrong) it will output all children posts of the parent post and <strong>not</strong> the parent post itself as well.</p>
<p>This problem might be solved by gathering all posts needed and putting them in parameter <code>post__in</code> like so:</p>
<pre><code>$args = array(
'post__in' => $children_and_parent_ids,
);
</code></pre>
<p>However there is <a href="https://developer.wordpress.org/reference/functions/wp_list_pages/" rel="noreferrer"><code>wp_list_pages()</code></a> allowing you to <code>include</code> a post(s) and specify the post where you want to include the children of (<code>child_of</code>). Why is this not possible with <code>WP_Query</code>?</p>
<p>An example of what I'm trying to achieve using <code>wp_list_pages()</code>:</p>
<pre><code>wp_list_pages(array(
'include' => $parent->ID,
'child_of' => $parent->ID,
));
</code></pre>
<p>Have a look at <a href="https://codex.wordpress.org/Class_Reference/WP_Query#Post_.26_Page_Parameters" rel="noreferrer">the documentation</a> of <code>WP_Query</code>.</p>

In some cases it might be useful to use multiple post & page parameters in your `WP_Query` object. In my case, I would like to display children of a parent page including the parent page itself.
Visualization of what I want to achieve. Imagine the following pages hierarchically sorted as following:
* page A
* **page B**
+ **Child page A**
+ **Child page B**
+ **Child page C**
* page C
The **bold list items** are the posts/pages I want to retrieve.
My first thoughts go out using these two parameters for `WP_Query`:
```
$args = array(
'post_id' => $parent->ID,
'post_parent' => $parent->ID,
);
```
Unfortunately, here it will only use one parameter. With the `$args` above (correct me if I'm wrong) it will output all children posts of the parent post and **not** the parent post itself as well.
This problem might be solved by gathering all posts needed and putting them in parameter `post__in` like so:
```
$args = array(
'post__in' => $children_and_parent_ids,
);
```
However there is [`wp_list_pages()`](https://developer.wordpress.org/reference/functions/wp_list_pages/) allowing you to `include` a post(s) and specify the post where you want to include the children of (`child_of`). Why is this not possible with `WP_Query`?
An example of what I'm trying to achieve using `wp_list_pages()`:
```
wp_list_pages(array(
'include' => $parent->ID,
'child_of' => $parent->ID,
));
```
Have a look at [the documentation](https://codex.wordpress.org/Class_Reference/WP_Query#Post_.26_Page_Parameters) of `WP_Query`.
|
We can filter the `posts_where` clause of the generated SQL to also return the parent post/page and not just the parent's children. Here we will set our own custom argument called `wpse_include_parent`, which, when set to `true`, will alter the generated SQL accordingly.
All we need to do inside our `posts_where` filter is to check if our custom argument is set and that the `post_parent` argument is set. We then get that value and pass it to the filter to extend our SQL query. What is nice here, `post_parent` excepts a single integer value, so we only need to validate the value as an integer.
THE QUERY
---------
```
$args = [
'wpse_include_parent' => true,
'post_parent' => 256,
'post_type' => 'page'
// Add additional arguments
];
$q = new WP_Query( $args );
```
As you can see, we have set `'wpse_include_parent' => true` to "activate" our filter.
THE FILTER
----------
```
add_filter( 'posts_where', function ( $where, \WP_Query $q ) use ( &$wpdb )
{
if ( true !== $q->get( 'wpse_include_parent' ) )
return $where;
/**
* Get the value passed to from the post parent and validate it
* post_parent only accepts an integer value, so we only need to validate
* the value as an integer
*/
$post_parent = filter_var( $q->get( 'post_parent' ), FILTER_VALIDATE_INT );
if ( !$post_parent )
return $where;
/**
* Lets also include the parent in our query
*
* Because we have already validated the $post_parent value, we
* do not need to use the prepare() method here
*/
$where .= " OR $wpdb->posts.ID = $post_parent";
return $where;
}, 10, 2 );
```
You can extent this as you need and see fit, but this is the basic idea. This will return the parent passed to `post_parent` and it's children

The error is most likely correct (and is most likely related to browser upgrade than any WP version change) and your theme/plugin does fishy things. The ajax enedpoint should be uses to return data - html/json/xml.
Wordpress will use the text/html mime type for all responses from the ajax endpoint without any simple way I can see to override it.
In addition to your existing problem, the ajax endpoint is blocked to search engines so you might be hurting your SEO if this code is used on the front end.
If it is not a theme you develop yourself, you should contact the theme/plugin author to fix the issue.

Thanks for all your help.
The key issues where that i needed to post the code in the functions.php file and needed to amend the if statement to read:
```
$query->is_main_query() && is_post_type_archive( 'festival' )
```
So that it would only effect my custom post type.
Thanks!

<p>I have very little space to host my WordPress website. That is why I want all my media files are stored in the cloud like dropbox, google drive etc.</p>
<p>For example, if a user wants to upload an image from the front-end using the common upload file button, then the image file is automatically stored directly to the cloud.</p>
<p>or</p>
<p>the image file will first stored in the upload folder then automatically moved into the cloud. So then my upload folder will always empty in order to save my very little space.</p>
<p>How can I do this?</p>

I have very little space to host my WordPress website. That is why I want all my media files are stored in the cloud like dropbox, google drive etc.
For example, if a user wants to upload an image from the front-end using the common upload file button, then the image file is automatically stored directly to the cloud.
or
the image file will first stored in the upload folder then automatically moved into the cloud. So then my upload folder will always empty in order to save my very little space.
How can I do this?

Thanks for all your help.
The key issues where that i needed to post the code in the functions.php file and needed to amend the if statement to read:
```
$query->is_main_query() && is_post_type_archive( 'festival' )
```
So that it would only effect my custom post type.
Thanks!

<p>I have a text widget, in it i just place there an iframe.</p>
<p>A few days ago i wanted to override this widget on mobile browsers and add a background of an image on mobile browsers, luckily i used <a href="https://woorkup.com/hide-wordpress-widgets-mobile-devices/" rel="nofollow">How to hide widget on mobile</a> , i changed the code from that link instead of hiding the widget on mobile i simply give it a background image.</p>
<p>Now my questions is how can i add an onclick function to this widget, for example when this widget is clicked on a mobile browser i call a shortcode.</p>
<p>Any code examples of how to add some javascript to a text widget so that when it is clicked i call a shortcode. </p>

We can filter the generated SQL query through the [`terms_clauses` filter](https://developer.wordpress.org/reference/hooks/terms_clauses/) before the SQL query is executed. What we will be doing is to introduce a new parameter called `wpse_parents` which will accept an array of parent term ID's to get children from. Note, this new parameter works exactly the same as the build-in parameter, `parent`, as it will return only direct children of the parent.
THE FILTER
----------
The code is commented for easy understanding and basic description of what a particular piece of code is doing. Note, all code requires at least PHP 5.4
```
add_filter( 'terms_clauses', function ( $pieces, $taxonomies, $args )
{
// Bail if we are not currently handling our specified taxonomy
if ( !in_array( 'speight_plans', $taxonomies ) )
return $pieces;
// Check if our custom argument, 'wpse_parents' is set, if not, bail
if ( !isset ( $args['wpse_parents'] )
|| !is_array( $args['wpse_parents'] )
)
return $pieces;
// If 'wpse_parents' is set, make sure that 'parent' and 'child_of' is not set
if ( $args['parent']
|| $args['child_of']

}, 10, 3 );
```
Just a note, the filter is build in such a way that it does not allow the `parent` and `child_of` parameters being set. If any of those parameters are set, the filter bails early and is not applied
BASIC USAGE
-----------
If you need to query child terms from terms 15 and 16, you can run the following query to achieve your goal
```
$args = [
'wpse_parents' => [15, 16]
];
$terms = get_terms( 'speight_plans', $args );
```

I have a custom post type that im trying to limit results in search.
The CPT is a deal/coupon, with a start and end date for each of the deals.
What I'm trying to do is only show these posts in search:
1. For non-recurring events....Show posts where the end date is today or after todays today.
**OR**
2. For recurring events, limit it to show only events with an end date between today which does not exceed 7 days.
Each of these queries works perfectly on their own, but I cant combine them together...
```
function search_pre_get_posts( $query ) {
if ( $query->is_search() && $query->is_main_query() ) {
$recurring_count = am_get_recurring_count($post->ID);
// Show non-recurring events with end date of today or after
if ($recurring_count == 0){
$currentdate = date('Y-m-d');
$query->set(
'meta_query',
array(
'relation' => 'OR',
array(
'key' => 'am_enddate',
'compare' => '>=',
'value' => $currentdate,
),
array(
'key' => 'am_enddate',
'compare' => 'NOT EXISTS',

)
);
$query->set( 'orderby', 'meta_value' );
$query->set( 'order', 'ASC' );
} else {
// Show recurring events with end date of today or after, that doesnt exceed 7 days.

We can filter the generated SQL query through the [`terms_clauses` filter](https://developer.wordpress.org/reference/hooks/terms_clauses/) before the SQL query is executed. What we will be doing is to introduce a new parameter called `wpse_parents` which will accept an array of parent term ID's to get children from. Note, this new parameter works exactly the same as the build-in parameter, `parent`, as it will return only direct children of the parent.
THE FILTER
----------
The code is commented for easy understanding and basic description of what a particular piece of code is doing. Note, all code requires at least PHP 5.4
```
add_filter( 'terms_clauses', function ( $pieces, $taxonomies, $args )
{
// Bail if we are not currently handling our specified taxonomy
if ( !in_array( 'speight_plans', $taxonomies ) )
return $pieces;
// Check if our custom argument, 'wpse_parents' is set, if not, bail
if ( !isset ( $args['wpse_parents'] )
|| !is_array( $args['wpse_parents'] )
)
return $pieces;
// If 'wpse_parents' is set, make sure that 'parent' and 'child_of' is not set
if ( $args['parent']
|| $args['child_of']
)
return $pieces;
// Validate the array as an array of integers
$parents = array_map( 'intval', $args['wpse_parents'] );
// Loop through $parents and set the WHERE clause accordingly
$where = [];
foreach ( $parents as $parent ) {
// Make sure $parent is not 0, if so, skip and continue
if ( 0 === $parent )
continue;
$where[] = " tt.parent = '$parent'";
}
if ( !$where )
return $pieces;
$where_string = implode( ' OR ', $where );
$pieces['where'] .= " AND ( $where_string ) ";
return $pieces;
}, 10, 3 );
```
Just a note, the filter is build in such a way that it does not allow the `parent` and `child_of` parameters being set. If any of those parameters are set, the filter bails early and is not applied

<p>I have tried so many solutions for this but I can't figure it out. Here is a simplified version of the plugin code:</p>
<pre><code>class YITH_Vendors_Frontend_Premium extends YITH_Vendors_Frontend {
public function __construct() {
add_action( 'woocommerce_register_form', array( $this, 'register_form' ) );
}
</code></pre>
<p>So I want to remove this action from my child themes function.php.</p>
<p>The problem is the class is not instanced via a variable. Instead it is instanced like this:</p>
<pre><code>class YITH_Vendors_Premium extends YITH_Vendors {
public function __construct() {
public function init() {
$this->frontend = new YITH_Vendors_Frontend_Premium();
}
}
}
</code></pre>
<p>This class however is never being instanced via variable. Instead there is a function that instances it:</p>
<pre><code>function YITH_Vendors() {
if ( defined( 'YITH_WPV_PREMIUM' ) ) {
return YITH_Vendors_Premium::instance();
}
return YITH_Vendors::instance();
}
</code></pre>
<p>And then it's just called like that:</p>
<pre><code>YITH_Vendors();
</code></pre>
<p>I tried all these but no chance:</p>
<pre><code>remove_action( 'woocommerce_register_form', array( "YITH_Vendors_Frontend", 'register_form' ), 999 );
remove_action( 'woocommerce_register_form', array( "YITH_Vendors_Frontend_Premium", 'register_form' ), 999 );
remove_action( 'woocommerce_register_form', array( "YITH_Vendors", 'register_form' ), 999 );

The problem here is `the_post_thumbnail()` doesn't return image url but the img tag.
You can use this code
```
$url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
echo '<li class="produkt" style="background: url('. $url.')">';
```

The problem here is `the_post_thumbnail()` doesn't return image url but the img tag.
You can use this code
```
$url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
echo '<li class="produkt" style="background: url('. $url.')">';
```

<p>I want to add an additional header to outgoing emails on my sites, so I can easily determine which site sent a given email. (I put a standard functionality plugin on all of my sites, so this is easy enough to do, and configuring my email client to filter and otherwise act on this header would be an amazing time-saver.)</p>
<p>I thought this would be a simple matter of plugging into the <code>wp_mail</code> function, but evidently it isn't.</p>
<p>First, I tried this:</p>
<pre><code>add_filter('wp_mail', 'ws_add_site_header');
function ws_add_site_header() {
return array('headers' => 'X-WU-Site: ' . parse_url(get_site_url(), PHP_URL_HOST));
}
</code></pre>
<p>Here, my array took precedence over anything else that modified the mail settings (say, Gravity Forms), so HTML emails started showing up as bare HTML and not nicely-formatted. Makes sense, since the Content-type: header that GF added was scrubbed. But my header was added to the email. Since others also depend on receiving pretty emails (all my sites' content developers and end-users, among others I'm sure), that isn't acceptable.</p>
<p>One of my colleagues then suggested routing my stuff through wp_parse_args(), thus:</p>
<pre><code>add_filter('wp_mail', 'ws_add_site_header');
function ws_add_site_header($args) {
$new_header = array('headers' => 'X-WU-Site: ' . parse_url(get_site_url(), PHP_URL_HOST));
return wp_parse_args($args, $new_header);
}
</code></pre>
<p>With that, it's as if my function doesn't exist -- my header isn't added, but neither are others' headers and mail settings stripped.</p>
<p>What's the correct way to add a header to an outgoing email, without scrambling up any other filters that might exist?</p>

I need to get attachment images with horizontal orientation. I tried to use `Meta_Query` but I don't know how to compare two values (**width** and **height**) from one associative array that is in `wp_postmeta` table. I don't have any specific values of width and height, I only need to compare this values which is in associative array.
Also tried to do this with `$wpdb` custom query:
```
$attach_ids = $wpdb->query( "
SELECT wp_posts.ID FROM wp_posts, wp_postmeta
WHERE EXISTS (SELECT * FROM wp_postmeta
WHERE meta_key = '_wp_attachment_metadata'

<p>Similar to the question over at <a href="https://wordpress.stackexchange.com/questions/72547/get-wp-logout-url-function-to-work-on-external-non-wordpress-page">Get wp_logout_url function to work on external (non-Wordpress) page</a></p>
<p>The problem I am facing is the fact the subdomain is on a different server so I am unable to include/require the <code>wp-blog-header.php</code> file.</p>
<p>Is there a way that I can whitelist domains that can allow instant logouts, like you can for the <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/allowed_redirect_hosts" rel="nofollow noreferrer">redirect whitelist</a>.</p>
<p>If not, how can I allow subdomains (it has remote sql access) to create a valid logout link that bypasses the "Are you sure you want to logout" notice.</p>
<h1>Re: @SatbirKira</h1>

Similar to the question over at [Get wp\_logout\_url function to work on external (non-Wordpress) page](https://wordpress.stackexchange.com/questions/72547/get-wp-logout-url-function-to-work-on-external-non-wordpress-page)
The problem I am facing is the fact the subdomain is on a different server so I am unable to include/require the `wp-blog-header.php` file.
Is there a way that I can whitelist domains that can allow instant logouts, like you can for the [redirect whitelist](https://codex.wordpress.org/Plugin_API/Filter_Reference/allowed_redirect_hosts).
If not, how can I allow subdomains (it has remote sql access) to create a valid logout link that bypasses the "Are you sure you want to logout" notice.
Re: @SatbirKira
===============
Does this like a logical work around to make sure the logout is "valid" to a certain degree:
* Set the logout URL every 24 hours to have a query string with a random string appended to it for example: `http://website.com/custom_logout.php?confirm=sj239ks`, followed by `http://website.com/custom_logout.php?confirm=32k9la3`
Each time it changes it would edit a specific file (custom\_logout.php on the other server OR a txt/ini file on its own server OR other server) and create an array/list of strings
```
$confirmkeys = array("sj239ks", "32k9la3");
```
or
```
[confirmkeys]
confirm[] = sj239ks
confirm[] = 32k9la3
```
It would only ever have 2 confirm keys in the file, one for 24 hours ago (just incase someone has the page still open) and one for the current 24 hours)
**I guess the same thing could be done individually instead of globally but is there much need for that?**
* Edit `custom_logout.php` to add a check to see if `$_SERVER['HTTP_REFERER']` is coming from the same domain (all subdomains). If it is then set `matching_referer` to true. If not set the variable to false.
* Edit `custom_logout.php` to add a check to see if the query string matches against one stored inside a specific file. (easiest to do with a txt/ini file on the secondary server?) If it matches then set `matching_confirm` to true. If not set the variable to false.
* Edit `custom_logout.php` and make it so as long if one (any) of the checks are true for it to logout cleanly, if they are both false logout with the warning by sending them to the `/wp-login.php?action=logout` page?

You can create a file called custom\_logout.php and place it in the root wordpress directory. This contains
```
<?php
require_once("wp-load.php"); //load wordpress
wp_logout(); //logout
exit(); //end page
?>
```
Then in your subdomain site open the url with an anchor tag
```
<a href="http://youwebsite.com/custom_logout.php">Logout</a>
```
You can't create a whitelist easily because it would involve checking where the user is coming from using $\_SERVER['HTTP\_REFERER'] which is unreliable(usually null). There is no simple solution for this unfortunately.
**Reply To Your Edit**
You are completely free to implement the temporary key approach if that is a responsible compromise. However, instead of two random keys you can send a md5 hash of the current day. Use an identical secret salt on both servers. Now you can simply recompute yesterday's hash and the current day's in custom\_logout.php and compare it to the get variable that is incoming.

<p>I have a function that stores the "like" status for a post as post meta. I want to associate that "like" with the user that liked it, so I setup a custom field called "like_status_{user_id}" (where {user_id} is the id of the currently logged in user) which I store as a 0 or 1. So for a post with several "likes" there would be several meta values in the db that are setup like this:</p>
<pre><code>'meta_key' = 'like_status_0'
'meta_value' = 1
'meta_key' = 'like_status_2'
'meta_value' = 1
'meta_key' = 'like_status_34'
'meta_value' = 1
</code></pre>
<p>....and so on.</p>
<p>There are potentially thousands of likes on a specific post.
How would I run a query that showed if someone else also liked that post?</p>
<p>I was thinking something like this:</p>
<pre><code>$query = new WP_Query(array(
'meta_key' => 'like_status_{user_id}',
'meta_value' => 1,
));
</code></pre>
<p>I'm trying to push a notification to everyone who has liked a post when someone else likes that post...something like, "Hey, someone else liked that post you liked. You should go check it out!" But I need a way to find out if anyone else has liked that post and if so, who they would be so I could notify them.</p>
<p>If it's not possible, could you suggest a better way of storing this data as post_meta while still keeping the efficiency of quickly updating a single user's like status on a post?</p>

I would however suggest storing all the user ID's in an array under one custom field. You can simply just update the array with the user ID when a user like a post. Getting the custom field data and looping over the array of ID's and doing something with the ID's are easy.

For that, you will need to look into <a href=\"https://developer.wordpress.org/reference/functions/update_post_meta/\" rel=\"noreferrer\"><code>update_post_meta()</code></a>, I do not know how you create your custom fields, but <code>update_post_meta()</code> is definitely something you would want to use.</p>\n\n<p>If you need to send emails or push notifications when a custom field is updated, you have the following hooks available to work with.

'meta_value' = 1
```
....and so on.
There are potentially thousands of likes on a specific post.
How would I run a query that showed if someone else also liked that post?
I was thinking something like this:
```
$query = new WP_Query(array(
'meta_key' => 'like_status_{user_id}',

If it's not possible, could you suggest a better way of storing this data as post\_meta while still keeping the efficiency of quickly updating a single user's like status on a post?

Unfortunately you cannot perform a `meta_query` using a `LIKE` comparison on the `meta_key` value when using `WP_Query`. I've been down this road...
Instead you have a couple other options if you want to maintain like status relationships as post meta and not user meta and or meta in a custom table.
Option 1
--------
* requires no modification of your meta schema
* uses `wpdb` class to perform a custom query
Example:
```
//when a user likes a post...
$current_user_id = get_current_user_id();
add_post_meta($current_user_id, "like_status_{$current_user_id}", 1, false);
//later in the request...
global $wpdb;
$results = $wpdb->get_results(
"
SELECT meta_key
FROM {$wpdb->prefix}postmeta
WHERE meta_key
LIKE 'like_status_%'
",
ARRAY_N
);
$results = array_map(function($value){
return (int) str_replace('like_status_', '', $value[0]);
}, $results);
array_walk($results, function($notify_user_id, $key){
//apply to all users except the user who just liked the post
if ( $notify_user_id !== $current_user_id ) {
//notify logic here...
}
});
```
Note: logic could be simplified further if you wish.
Option 2
--------
* requires you change your meta schema
* requires you store the user id as the meta value
* allows you to use `WP_Query` along with `meta_query`
Option 2 requires that you change your meta key from `like_status_{user_id}` to something universal such as `like_status` or `liked_by_user_id` where in turn instead of storing the value of `1` against the key, you instead store the user's id as the value.
```
//when a user likes a post...
$current_user_id = get_current_user_id();
add_post_meta($current_user_id, "liked_by_user_id", $current_user_id, false);
//later in the request
$args = array(
'post_type' => 'post', //or a post type of your choosing
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'liked_by_user_id',
'value' => 0,
'type' => 'numeric'
'compare' => '>'
)
)
);
$query = new WP_Query($args);
array_walk($query->posts, function($post, $key){
$user_ids = get_post_meta($post->ID, 'liked_by_user_id');
array_walk($user_ids, function($notify_user_id, $key){
//notify all users except the user who just like the post
if ( $notify_user_id !== $current_user_id ) {
//notify logic here...
//get user e.g. $user = get_user_by('id', $notify_user_id);
}
});
});

I want to set a number of plugin options set to blank if they are not defined so I can avoid the PHP notices.
What is a better way of writing this code?
```
$options = get_option('plugin_options');
// Add new plugin options defaults here
if( !isset( $options['plugin_option_1'] ) ) $options['plugin_option_1'] = '';
if( !isset( $options['plugin_option_2'] ) ) $options['plugin_option_2'] = '';
if( !isset( $options['plugin_option_3'] ) ) $options['plugin_option_3'] = '';
if( !isset( $options['plugin_option_4'] ) ) $options['plugin_option_4'] = '';
if( !isset( $options['plugin_option_5'] ) ) $options['plugin_option_5'] = '';
```
New options would need to be added in future updates to the plugin.

WordPress provides a default method, [`wp_parse_args`](http://php.net/manual/en/function.array-merge.php), to combine a set of default options and a user-defined set of options. This method uses PHP's native [`array_merge`](http://php.net/manual/en/function.array-merge.php) for arrays, but also works when either of the two option sets is an object or a WordPress [options string](https://developer.wordpress.org/reference/functions/wp_parse_str/).
You simply provide an array of default options and an array of set options, and WordPress fills the options that are missing in the options set by their default value.
You can find this code, adjusted for your example, below:
```
$options = get_option( 'plugin_options' );
$options_default = array(
'plugin_option_1' => '',
'plugin_option_2' => '',
'plugin_option_3' => '',
'plugin_option_4' => '',
'plugin_option_5' => ''
);
$options = wp_parse_args( $options, $options_default );
```

<p>I'm not sure why this is not working as its a very simple query. It works when i pull all posts including pending, but not when i want to get posts that are only published.</p>
<p>I have a function to get posts. I pass in a bool variable. If its true, i want to pull all posts from a custom post type called books, including ones that are pending/draft. If false i only want the published posts. I see no issues with the code, but it wont work.</p>
<pre><code>$args = array(
'post_type' => 'book',
'showposts' => -1,

if($getpending == true) $args["post_status"] = "any";

First off, you probably shouldn't be using `query_posts`, which modifies WordPress' main loop and is unsuited for pretty much any purpose (read [When should you use WP\_Query vs query\_posts() vs get\_posts()?](https://wordpress.stackexchange.com/questions/1753/when-should-you-use-wp-query-vs-query-posts-vs-get-posts) for more info). There are numerous reasons why `query_posts` wouldn't work as expected in this case.
WordPress has two proper approaches to fetching posts: the [`WP_Query`](https://codex.wordpress.org/Class_Reference/WP_Query) object and the [`get_posts`](https://codex.wordpress.org/Template_Tags/get_posts) function. They work very similarly, with `get_posts` using `WP_Query` internally. However, as one would expect, `WP_Query` allows for more control.
For your case, `get_posts` should work (as there is no further flaw in the code you posted).

<p>I want to display image title and caption inside a <code><p></code> tag in single post in <code>the_content()</code> function for every image that has one. So for example if I add gallery, and define title for every image, I want to have above every image it's title displayed, and below every image it's caption displayed, and also for all single images if they have title defined.

I want to display image title and caption inside a `<p>` tag in single post in `the_content()` function for every image that has one. So for example if I add gallery, and define title for every image, I want to have above every image it's title displayed, and below every image it's caption displayed, and also for all single images if they have title defined. To visually express it:

I got a few minutes and made the custom code for you.
Copy and paste this in your themes functions.php
```
remove_shortcode('gallery', 'gallery_shortcode');
add_shortcode('gallery', 'gallery_shortcode_custom');
function gallery_shortcode_custom( $attr ) {
$post = get_post();
static $instance = 0;
$instance++;
if ( ! empty( $attr['ids'] ) ) {
// 'ids' is explicitly ordered, unless you specify otherwise.
if ( empty( $attr['orderby'] ) ) {
$attr['orderby'] = 'post__in';
}
$attr['include'] = $attr['ids'];
}

<p>I have created custom tables for performance reasons for products, carts, and notifications. I want to make these tables and their data available for normal CRUD via the WP REST API v2. How would I add custom tables (and their columns) to the API so that I could get/update those records?</p>

You need to have a super great reason to disable CORS, as no real reason was given here the answer should be "do not do it, it is not secure".
You assume that no one can craft a feed link which will give him a write access. This might be true, but you should not open holes in your security based on "assuming".
In the very least, if some other domain needs "AJAX" access to your feeds, you should disable CORS only for that specific domain.
In addition `pre_get_posts` is totally the wrong place to do it, and you should do it on `init`. The way your code is currently written it may disable CORS for pages which are not feed.

<p>Just today I synchronized a development website database with a production website database. </p>
<p>Now, my development website gives a "404 Not Found" error. The URL starts with HTTPS, and there is a red slash through the HTTPS text. The 404 page says "The server can not find the requested page: dev.greenbee-web.com/ilaimh/wp-admin/ (port 443). Apache Server at dev.greenbee-web.com Port 443".</p>
<p>I did not realize that the production website uses HTTPS ( I am an employee and so I'm not the only one working on this website). This made the development website now use HTTPS, but I want it to use HTTP. I can't figure out where, in any of WordPress's configuration files, I can make the development website go back to using HTTP.</p>
<p>Is there some setting in wp-config that is forcing my development site to use HTTPS? If not in wp-config, where is the setting that is forcing the site to use HTTPS?</p>
<p>Thank you</p>

There are 2 things you must do.
If you are using Apache server go to .htaccess and change the Rewrite and RewriteBase engine to
```
RewriteEngine On
RewriteCond %{SERVER_PORT} ^443$
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R=301,L]
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
```
If you are using Nginx something like this should work
```
server {
listen 80 443;
server_name example.com;
# add ssl settings
return 301 https://example.com$request_uri;
}
```
This would redirect the https to http
and go to the database through phpmyadmin or whatever you use
go to wp\_options and find and change the siteurl and home values from <https://example.com> to <http://example.com>
Clean your cache and try again. It should work without problem.
If the site still asks for SSL check your wp-config.php file to see if it has this code
```
define('FORCE_SSL_ADMIN', true);
```
then change the 'true' to 'false'
Hope this helps you.

<p>In wordpress, to use $ instead of jQuery prefix, i added the following code around all js code:</p>
<pre><code>jQuery(function($) {
...
});
</code></pre>
<p>It works well, but i cannot call an object from another javascript file, the following problem persists:</p>
<pre><code>Slider is not defined
</code></pre>
<p>This is my code:</p>
<p><strong>file1.js</strong></p>
<pre><code>jQuery(function($) {
var slider = new Slider();
});
</code></pre>
<p><strong>file2.js</strong></p>
<pre><code>jQuery(function($) {
function Slider() {
this.nb_ele = 10;
}
});
</code></pre>
<p>It seems that because the workspace of two js files is different so they can't call function from another one. Any solution?</p>

In wordpress, to use $ instead of jQuery prefix, i added the following code around all js code:
```
jQuery(function($) {
...
});
```
It works well, but i cannot call an object from another javascript file, the following problem persists:
```
Slider is not defined
```
This is my code:
**file1.js**
```
jQuery(function($) {
var slider = new Slider();
});
```
**file2.js**
```
jQuery(function($) {
function Slider() {
this.nb_ele = 10;
}
});
```
It seems that because the workspace of two js files is different so they can't call function from another one. Any solution?
|
The issue you have is that `Slider` is not accessible outside of its scope as that's defined by the `.ready()` though you've used shorthand for that. The function needs to be available in the global scope:
file1.js
```
function Slider() {
this.nb_ele = 10;
}
jQuery(function($) {
// ...
});
```
file2.js
```
jQuery(function($) {
var slider = new Slider();
});
```
If you want Slider to stay in the document ready, you'll need to use a function expression to add the function to the global object:
```
jQuery(function($) {
window.Slider= function () {
this.nb_ele = 10;
};
});
```

I am literally pulling my hair out trying to figure this out. I have been at it for almost 12 hours now.
Being new to PHP and theme development I am having a hard time understanding how to get `theme_options('value');` to display when putting in a PHP stylesheet.
I have taken an example off a blog post I read [here](https://josephscott.org/archives/2010/03/database-powered-css-in-wordpress-themes/) using the parse\_request method.
code in `header.php`
```
<link rel='stylesheet' type='text/css' href="<?php echo get_template_directory() ?>/css/theme_styles.php?my-custom-content=css" />
```
and in `theme-styles.php`
```
<?php
add_action( 'parse_request', 'my_custom_wp_request' );
function my_custom_wp_request( $wp ) {
if ( !empty( $_GET['my-custom-content'] ) && $_GET['my-custom-content'] == 'css' ) {
# get theme options
header( 'Content-Type: text/css' );
?>
a { color: <?php echo get_option('some_other_option') ?> !important; }
<?php
exit;
}
}
?>
```

Although @Jevuska did solve my issue, I have found a much easier solution to adding dynamic CSS from my theme options page. Here we go!
Add this to **functions.php**
```
add_action('wp_head', 'my_custom_css');
function my_custom_css(){
require_once( get_template_directory() . '/css/theme-styles.php' );
}
```
Now you can treat **theme-styles.php** as a normal CSS stylesheet
```
<style type="text/css">
a {
color: <?php echo get_option('some_other_option');?> !important;
}
</style>
```
Done! It was that simple.

`query_posts()` can alter the WP query even when it is executed and it should be placed at least before you start the loop i.e. `have_posts()`. Currently you are placing it after setting up post data i.e. `the_post()`. Which is resulting in unexpected behavior.
**Example:**
```
global $query_string; //Get current query arguments
query_posts($query_string."&featured=yes");
if (have_posts()) {
while (have_posts()) {
the_post(); ?>
<? php the_author(); ?>
<? php

the_post_thumbnail('thumbnail');

`query_posts()` can alter the WP query even when it is executed and it should be placed at least before you start the loop i.e. `have_posts()`. Currently you are placing it after setting up post data i.e. `the_post()`. Which is resulting in unexpected behavior.
**Example:**
```
global $query_string; //Get current query arguments
query_posts($query_string."&featured=yes");
if (have_posts()) {
while (have_posts()) {
the_post(); ?>
<? php the_author(); ?>
<? php
if (has_post_thumbnail()) {
the_post_thumbnail('thumbnail');
} ?>
<a href = "<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php the_excerpt(); ?>
<a href = "<?php the_permalink(); ?>"> Read More.... </a>
<?php
} // end while
} // end if
```

On a page in Wordpress, If I enter the following code:
```
var r='<li><a href="#"><img src="' + slide.src + '" width="50" height="50" /></a></li>';
```
it is rendered in the browser as
```
var r='
<li><a href="#"><img src="' + slide.src + '" width="50" height="50" /></a></li>
';
```
and it gives me this error in FF Console `SyntaxError: unterminated string literal var r='`
This is a single-user blog, so I am "Administrator".
How do I prevent Wordpress from fouling my code?

In the new WordPress (WP 5+) Editor - Gutenberg, you can use a "Custom HTML" block to prevent the automatic line breaks and paragraphs:
on Visual Editor click + > Formatting > Custom HTML - and put your JavaScript in there
on Code Editor enclose your JavaScript with `<!-- wp:html --> <!-- /wp:html -->`

<p>I'm trying to modify a theme to make it work with my custom fields (I'm using ACF for most of the data I put on pages) for a site with song lyrics on it.
The original code was this:</p>
<pre><code>$metro_creativex_posttitle = get_the_title();
$metro_creativex_feat_image = wp_get_attachment_image_src(
get_post_thumbnail_id( $post->ID ),
'single-post-thumbnail'
);
if(isset($metro_creativex_feat_image[0])):
echo '<div class="img">'.get_the_post_thumbnail().'</div>';
endif;
</code></pre>
<p>It's a piece of the <code>content.php</code> that shows the posts in categories pages.
Now, since my posts don't have any featured images but only one or two images via custom fields, my first intent is to replace the 'custom thumbnail' with the single cover art, so first thing first I replaced the <code>get_post_thumbnail</code> with a <code>get_field</code>, and it at least seems to detect whenever a song has or not a single cover picture:</p>
<pre><code>$metro_creativex_posttitle = get_the_title();
$metro_creativex_feat_image = wp_get_attachment_image_src(
$post->ID,
get_field('sd_single_img'),
'single-post-thumbnail'
);
if(isset($metro_creativex_feat_image[0])):
echo '<div class="img">'.get_the_post_thumbnail().'</div>';
endif;
</code></pre>
<p>My main problem for now is that I can't understand what I have to write down on the <code>echo</code> to make it show the actual image and not only a blank space above the song title on the category menu: <a href="http://www.thenewblackgold.netsons.org/wp/category/songs/level-1/" rel="nofollow">Link to my page</a></p>
<p>How can I fix it?</p>

The code you are using is correct. The problem is that you are looking at `thumbnail`s that have already been created. As @Loius mentioned you will need to use [Regenerate Thumbnails](https://wordpress.org/plugins/regenerate-thumbnails/) to see the effect. Why core has not implemented this is beyond me.

<p>I work on a theme that displays <strong>3 columns</strong> with images, so the size for thumbnails on large displays will be 360x240px.</p>
<p>When resized, on some <strong>mobile</strong> devices, like iPhone, there will be just <strong>1 column</strong> with images, which may result that the <strong>featured image will be larger</strong> than 360px in width.</p>
<p>Now, in order to maintain a good PageSpeed score, I don't want to load a larger image size on desktop computers and scale it via CSS, but on mobile devices I need the Featured Image to be larger, like 640x426px.</p>
<p>The problem in using the same image size on mobile devices is that it may not be large enough to fill 1 column, and would leave some <strong>empty space</strong> next to it.</p>
<p>I've registered 2 new image sizes, but it seems that the <code>the_post_thumbnail()</code> function always picks the wrong one.</p>
<pre><code>add_image_size( 'loop', 360, 240, true );
add_image_size( 'loop-mobile', 640, 426, true );
</code></pre>
<p>I've tried different methods, and none of them is close to what I need: </p>
<ol>
<li><p><code>the_post_thumbnail();</code></p>
<p>In this case the image is too small on mobile devices </p></li>
<li><p><code>the_post_thumbnail('loop-mobile');</code></p>
<p>In this case it will always load the larger version 640x426px, which affects the PageSpeed score </p></li>
<li><p><code>the_post_thumbnail(array(640,426));</code></p>
<p>Same problem with PageSpeed score.</p></li>
</ol>
<p>Thanks for help!</p>

I work on a theme that displays **3 columns** with images, so the size for thumbnails on large displays will be 360x240px.
When resized, on some **mobile** devices, like iPhone, there will be just **1 column** with images, which may result that the **featured image will be larger** than 360px in width.
Now, in order to maintain a good PageSpeed score, I don't want to load a larger image size on desktop computers and scale it via CSS, but on mobile devices I need the Featured Image to be larger, like 640x426px.
The problem in using the same image size on mobile devices is that it may not be large enough to fill 1 column, and would leave some **empty space** next to it.
I've registered 2 new image sizes, but it seems that the `the_post_thumbnail()` function always picks the wrong one.
```
add_image_size( 'loop', 360, 240, true );
add_image_size( 'loop-mobile', 640, 426, true );
```
I've tried different methods, and none of them is close to what I need:
1. `the_post_thumbnail();`
In this case the image is too small on mobile devices
2. `the_post_thumbnail('loop-mobile');`
In this case it will always load the larger version 640x426px, which affects the PageSpeed score
3. `the_post_thumbnail(array(640,426));`
Same problem with PageSpeed score.
Thanks for help!

The answer is to use WP's responsive images, customising the sizes attribute to suit your use case.
Reading between the lines, I'm assuming here that you are using a responsive design approach to show the different layouts at different widths.
The easiest way is to start by making yourself a replacement template tag function for `the_post_thumbnail`:
```
function wpse_221989_the_post_thumbnail( $size, $attr ) {
the_post_thumbnail( $size, $attr );
}
```
Where you call `the_post_thumbnail` in your templates, call `wpse_221989_the_post_thumbnail` instead. Why do we do it like this? WP doesn't give you any context on the filter hooks to modify `srcset` and `sizes` attributes for responsive images, so we are making our own context with the `wpse_221989_the_post_thumbnail` wrapper function.
So far, nothing clever, but now we can build upon this function to:
1 - draw on a set of image sizes
2 - ask the browser to choose a suitable image depending upon your responsive breakpoint for this particular use case
1 - In your instance, where your image versions are all the same aspect ratio, WP handles things for us. Using a built-in image call like `the_post_thumbnail` will build a `srcset` attribute from every image size you have with the same aspect ratio as the image specified in the `$size` parameter. You can use `add_image_size` to create additional versions large enough for high density displays too. WP's match on aspect ratio allows for small rounding errors, so both the sizes in your question should be matched OK.
2 - To get the browser to choose the right image size for the space, you will need a custom `sizes` attribute. WP's default `sizes` attribute assumes that you want an image to be full browser width, but no wider than the image's natural width. In your design, narrower screens need the larger image and then above a certain breakpoint you want to choose the smaller image width.
So, assuming from your image sizes that your breakpoint is at `640px`, we'd want a `sizes` attribute a bit like this: `(min-width: 640px) 33.333vw, 100vw`
What this says to the browser is for windows of `640px` width and over, choose the image from the `srcset` list that best matches a third of the window width. For other window widths (< 640px) choose an image from the list that best fits the full window width.
To put that into code we make a new function to return the attribute and build it into our wrapper function:
```
function wpse_221989_sizes() {
return "(min-width: 640px) 33.333vw, 100vw";
}
function wpse_221989_the_post_thumbnail( $size, $attr ) {
add_filter( 'wp_calculate_image_sizes', 'wpse_221989_sizes', 10 , 2 );
the_post_thumbnail( $size, $attr );
remove_filter( 'wp_calculate_image_sizes', 'wpse_221989_sizes', 10 );
}
```
Now when your theme template calls `wpse_221989_the_post_thumbnail` our custom `sizes` attribute will be substituted for the default. By hooking into the filter before calling `the_post_thumbnail` and unhooking immediately after we make our custom template tag function sensitive to the context of your question without upsetting any sizes attributes generated on images in other parts of your theme.
You can build upon this by putting in conditional checks on `$size` to choose different rules for the various image versions you've created for your theme to use.
If Google Pagespeed is important to you then test to see that it is obeying your `srcset` and `sizes` attributes. If not, then use `add_image_size` to make a size that just fits the Pagespeed window and use that size in your calls to `wpse_221989_the_post_thumbnail` so that it is put into the `src` attribute. On my sites I use a 1024px image as the default which seems to keep both desktop and mobile Pagespeed analyses happy.

<p>Several years ago, not really having a handle on the best practice for running a MultiSite network, I often network activated plugins. Later I realized this was a mistake because not all the sites used some of the plugins. So I have unnecessary scripts and stylesheets on several sites. </p>

For example, <a href="https://wordpress.org/plugins/advanced-recent-posts/" rel="nofollow">https://wordpress.org/plugins/advanced-recent-posts/</a> is not following my function.

If the theme mod option has a value in database, your code is working just fine as it should return the value in database and ignore the second parameter. The second parameter is the default value to be used if there is no value is set. And the value is stored in database.
The problem is that you are wrong considering that the values of the theme mod are cached in database, **they are stored in database**, not cached; the query to get them from database can be cached but if you need to update the value of a theme mod, you have to update the value already stored in database. You can do it using [`set_theme_mod()`](https://codex.wordpress.org/Function_Reference/set_theme_mod):
```
set_theme_mod( 'parallax_one_logos_content', 'new value' );
```

Just like in topic I try to order posts from category by date and comment\_count but code below doesn't work:
```
<?php
//get post from current category
$category = get_the_category();
$category_ID = $category[0]->term_id;
$args = array(
'cat' => $category_ID,
//limit posts to 3
'posts_per_page' => 3,
'ignore_sticky_posts' => true,
//order post by date and comments
'orderby' => array(
'date' => 'DESC',
'comment_count' => 'DESC',
),
);
$the_query = new WP_Query($args);
?>
```
Posts are ordered only by date
|
The query you currently have will order the posts by their `post_date` property, which is an SQL column of the type `datetime`. This type stores the date, but also the time (hours, minutes and seconds). The second sorting option, `comment_count`, is only applied to posts with the same timestamp, i.e. that were posted at the exact same second in time.
So, the solution to your problem is to sort by post *date* instead of *datetime*. To do so, you can filter the `orderby` query part in `WP_Query` using the filter [`posts_orderby`](https://codex.wordpress.org/Plugin_API/Filter_Reference/posts_orderby). With this filter, you can replace the SQL `ORDER` clauses to use the day instead of the datetime.
The code below does this: it adds a function to the filter `posts_orderby` which replaces the `{$wpdb->posts}.post_date` (e.g. `wp_posts.post_date`) by `CAST({$wpdb->posts}.post_date AS DATE)`, which casts the datetime field to `YYYY-MM-DD` format. After executing the query, it removes the filter, ensuring that other queries are not affected.
```
function wpse222104_query_orderby_day( $orderby, $query ) {
global $wpdb;
return str_replace( "{$wpdb->posts}.post_date", "CAST({$wpdb->posts}.post_date AS DATE)", $orderby );
}
// Add the filter to change the ORDER clause
add_filter( 'posts_orderby', 'wpse222104_query_orderby_day', 10, 2 );
// Run the query with the filters
$query = new WP_Query( $args );
// Remove the filter
remove_filter( 'posts_orderby', 'wpse222104_query_orderby_day' );
```
This assumes the same `$args` that you already had: there was nothing wrong with them.
Testing the code
----------------
Testing the code shows that the `ORDER BY` clause is correctly changed: the original clause was
```
wp_posts.post_date DESC, wp_posts.comment_count DESC
```
whereas the new one is
```
CAST(wp_posts.post_date AS DATE) DESC, wp_posts.comment_count DESC
```
Example
-------
The precise time the post was published will now not be considered in sorting: only the date it was posted will. For example, consider the following posts:
```
Title Date Comment count
Example Post 2014-12-16 10:12:16 6
Another one 2014-12-16 21:50:07 4
Yet Another 2012-08-02 11:15:20 25
```
Here, your original query would return the posts in the order
1. Another one
2. Example post
3. Yet another
Whereas the new code would return the posts in order
1. Example post
2. Another one
3. Yet another
as "Example post" and "Another one" were posted on the same day, but "Example post" has more comments.

One of the ways is to extend `Walker_Page` class. See comment in the code to know where changes go.
```
class My_Siblings_CSS_Walker_Page extends Walker_Page {
public function start_el( &$output, $page, $depth = 0, $args = array(), $current_page = 0 ) {
if ( $depth ) {
$indent = str_repeat( "\t", $depth );
} else {
$indent = '';
}
$css_class = array( 'page_item', 'page-item-' . $page->ID );
if ( isset( $args['pages_with_children'][ $page->ID ] ) ) {
$css_class[] = 'page_item_has_children';
}
if ( ! empty( $current_page ) ) {
$_current_page = get_post( $current_page );
if ( $_current_page && in_array( $page->ID, $_current_page->ancestors ) ) {
$css_class[] = 'current_page_ancestor';
}
if ( $page->ID == $current_page ) {
$css_class[] = 'current_page_item';
} elseif ( $_current_page && $page->ID == $_current_page->post_parent ) {
$css_class[] = 'current_page_parent';
}
} elseif ( $page->ID == get_option('page_for_posts') ) {
$css_class[] = 'current_page_parent';
}
$css_classes = implode( ' ', apply_filters( 'page_css_class', $css_class, $page, $depth, $args, $current_page ) );
if ( '' === $page->post_title ) {
$page->post_title = sprintf( __( '#%d (no title)' ), $page->ID );
}
$args['link_before'] = empty( $args['link_before'] ) ? '' : $args['link_before'];
$args['link_after'] = empty( $args['link_after'] ) ? '' : $args['link_after'];
$output .= $indent . sprintf(
// '<li class="%s"><a href="%s">%s%s%s</a>', // before
'<li class="%s"><a href="%s" class="my-custom-css-class">%s%s%s</a>', // after
$css_classes,
get_permalink( $page->ID ),
$args['link_before'],
apply_filters( 'the_title', $page->post_title, $page->ID ),
$args['link_after']
);
if ( ! empty( $args['show_date'] ) ) {
if ( 'modified' == $args['show_date'] ) {
$time = $page->post_modified;
} else {
$time = $page->post_date;
}
$date_format = empty( $args['date_format'] ) ? '' : $args['date_format'];
$output .= " " . mysql2date( $date_format, $time );
}
}
}
```
Use this custom Walker in your template:
```
$args = array(
'sort_column' => 'menu_order',
'title_li' => '',
'child_of' => $post->post_parent
'walker' => new My_Siblings_CSS_Walker_Page() // use Walker here
);
// $childpages = wp_list_pages($args);
wp_list_pages($args); // as you utilize default 'echo' parameter (true)
```
The way much easier is to use jQuery.

You could try the `tax_query` with the `'NOT IN'` operator (untested)
```
$myposts = get_posts(
[
'tax_query' => [
[
'taxonomy' => 'post_tag',
'terms' => [ 'index' ],
'field' => 'slug',
'operator' => 'NOT IN',

]

);
```
where the taxonomy slug for *tags* is `post_tag`.

<p>Basically on my site I have a bunch of song lyrics and in a static page I want to show them listed by album <a href="http://www.thenewblackgold.netsons.org/wp/indexes/by-album/" rel="nofollow">Link to my website</a> and album position of the song and I have two custom fields with that data, <code>sd_album_title</code> and `sd_album_track_n.<br />
Plus some of the songs don't have an album yet, so both values are void, and I wish to list those ones at the foot of the others, sorted by alphabetical order. <br />
The latest thing I tried at least to sort everything by the two field is this one:</p>
<pre><code>$key = 'sd_album_title';
$themeta = get_post_meta($post->ID, $key, TRUE);
add_filter( 'pre_get_posts', 'my_get_posts' );
function my_get_posts( $query ) {
if ($themeta != '') {
$query->set( 'post_type', 'lyric' );
$query->set( 'meta_key', 'sd_album_title' );
$query->set( 'orderby', 'meta_value' );
$query->set( 'order', 'ASC' );
$query->set( 'meta_query', array(
array(
'key' => 'sd_album_title'
),
array(
'key' => 'sd_album_track_n',
'value' => 'target_value',
'compare' => '>=',
'type' => 'numeric'
)
));
}
return $query;
}
$getlist= 'my_get_posts';
$posts = get_posts( $getlist );
</code></pre>
<p>And my intention was to put an else at the end of it with an array ordered by title for the other songs, but it returns nothing as it is.<br />
Could something like this work with some corrections or am I on a totally wrong path?</p>

Basically on my site I have a bunch of song lyrics and in a static page I want to show them listed by album [Link to my website](http://www.thenewblackgold.netsons.org/wp/indexes/by-album/) and album position of the song and I have two custom fields with that data, `sd_album_title` and `sd\_album\_track\_n.
Plus some of the songs don't have an album yet, so both values are void, and I wish to list those ones at the foot of the others, sorted by alphabetical order.
The latest thing I tried at least to sort everything by the two field is this one:
```
$key = 'sd_album_title';
$themeta = get_post_meta($post->ID, $key, TRUE);
add_filter( 'pre_get_posts', 'my_get_posts' );
function my_get_posts( $query ) {
if ($themeta != '') {
$query->set( 'post_type', 'lyric' );
$query->set( 'meta_key', 'sd_album_title' );
$query->set( 'orderby', 'meta_value' );
$query->set( 'order', 'ASC' );
$query->set( 'meta_query', array(
array(
'key' => 'sd_album_title'
),
array(
'key' => 'sd_album_track_n',
'value' => 'target_value',
'compare' => '>=',
'type' => 'numeric'
)
));
}
return $query;
}
$getlist= 'my_get_posts';
$posts = get_posts( $getlist );
```
And my intention was to put an else at the end of it with an array ordered by title for the other songs, but it returns nothing as it is.
Could something like this work with some corrections or am I on a totally wrong path?

Why you are using `pre_get_posts` when using your own `get_posts()` ? You can just pass the argument list directly to `get_posts()`.
`orderby` can accept array of arguments and can order by multiple values.
First name the indexes of meta queries array. This can be anything to use in orderby parameter. e.g.
```
'meta_query' => array(
'album_title_meta' => array(
'key' => 'sd_album_title',
'compare' => 'EXISTS',
),
'album_track_n_meta' => array(
'key' => 'sd_album_track_n',
'value' => 'target_value',
'compare' => '>=',
'type' => 'numeric'
)
),
```
Then pass an array in `orderby`, constructed using these keys!
```
'orderby' => array(
'album_title_meta' => 'ASC',
'album_track_n_meta' => 'DESC',
),
```
First, posts will be order by album title, ASC then track number, DESC.
**The complete example:**
```
$my_args = array(
'post_type' => 'lyric',
'meta_query' => array(
'album_title_meta' => array(
'key' => 'sd_album_title',
'compare' => 'EXISTS',
),
'album_track_n_meta' => array(
'key' => 'sd_album_track_n',
'value' => 'target_value',
'compare' => '>=',
'type' => 'numeric'
)
),
'orderby' => array(
'album_title_meta' => 'ASC',
'album_track_n_meta' => 'DESC',
),
);
$getlist = get_posts($my_args);
```

I have a daily wp schedule event.
I know that it happens when a user visits the site and if a schedule time passes.
If I started it on today 12 a.m. and if tomorrow first visitor comes tomorrow 1:20 a.m. that event happen tomorrow 1:20 a.m..
Day after day, it happens after 1.20 a.m. or after 12 a.m.?

*wp-cron* is often called a pseudo-cron, because it doesn't run on a strict schedule. If nobody visits the site, it doesn't run. If you schedule a wp-cron event to run, say, every 12 hours, it will run *at most* every 12 hours. But, if your site has very little traffic, there could be far more than 12 hours between runs.
If you need an event to happen every 12 hours, or every day at the same time, you'll need to use something outside of WordPress. Common approaches to that include using the system task scheduler (on Linux, this is usually called "cron") or a third-party service like EasyCron.
Assuming you're on a Linux server (by far the most common hosting environment), create a small shell script that looks like this:
```
#!/bin/bash
curl http://yoursite.name.com/wp-cron.php >/dev/null
```
This will run the "curl" command, to load your site's wp-cron.php page, then immediately ignore the results (by dumping the output to /dev/null). You don't care about any output the page might have, and in fact there normally isn't any output. You just want to be sure the page is loaded.
Then, add a line to your crontab ("crontab -e" will open the crontab file in your default editor, probably *vi*) that looks something like this:
```
0 0,12 * * * /home/user/touch-site.sh
```
(Obviously, modify the file location to wherever you put your script. Also, be sure the script is executable by running "chmod 700 touch-site.sh".)
This example will visit your site daily, at noon and midnight (server time), and run the wp-cron script. For more details on how this file works, run "man crontab".

<p>I am pretty new to WordPress API, loving it btw, I have a small project, adding a like button to the end of every post, pressing it makes user like the post, button changes to dislike, pressing again makes user dislike the post.</p>
<p>Without the knowledge of WordPress API, I planned to create a table for my plugin in wpdb which I will store the post-id and user-ids. Plugin will know by querying the table if the user has already liked the post. But on the internet I found a lot of examples of like buttons, not creating a custom table and using update_post_meta, and if I understood right update_post_meta does not alter any table in the database or insert new rows. Because I tried some of the plugins which uses update_post_meta and after liking a post, my wp_posts and wp_postmeta tables does not change at all.</p>
<p>My question is where exactly is post_meta stored, where does wordpress store the new custom field 'like_count' if I do this;</p>
<pre><code>update_post_meta($post_id, 'like_count',1);
</code></pre>

But on the internet I found a lot of examples of like buttons, not creating a custom table and using update\_post\_meta, and if I understood right update\_post\_meta does not alter any table in the database or insert new rows. Because I tried some of the plugins which uses update\_post\_meta and after liking a post, my wp\_posts and wp\_postmeta tables does not change at all.
My question is where exactly is post\_meta stored, where does wordpress store the new custom field 'like\_count' if I do this;
```
update_post_meta($post_id, 'like_count',1);
```
|
Yes, we can use existing tables in WordPress for storing the values.
Post meta fields are stored in the `{$wpdb->prefix}_postmeta` table (depending on the table prefix; `wp_postmeta` by default). If the meta key `"like_count"` is already present in the table along with the post ID then `update_post_meta()` will update this, and otherwise this function will insert a new row with this key.

I did this for a client and it looked like this:
The PHP code:
```
<dl class="tree-accordion">
<?php
$currentyear = date("Y");
$years = range($currentyear, 1950);
foreach($years as $year) { ?>
<dt><a href=""><i class="fa fa-fw fa-plus-square-o" aria-hidden="true"></i> <?php echo $year; ?></a></dt>
<?php
$archi = wp_get_archives('echo=0&show_post_count=1&type=monthly&year=' . $year);
$archi = explode('</li>', $archi);
$links = array();
foreach($archi as $link) {
$link = str_replace(array('<li>', "\n", "\t", "\s"), '' , $link);
if('' != $link)
$links[] = $link;
else
continue;
}
$fliplinks = array_reverse($links);
if(!empty($fliplinks)) {
echo '<dd>';
foreach($fliplinks as $link) {
echo '<span>' . $link . '</span>';
}
echo '</dd>';
} else {
echo '<dd class="tree-accordion-empty"></dd>';
}
?>
<?php } ?>
</dl>
```
The archives override filter:
```
/*
* Add filter to query archives by year
*/
function newmarket_getarchives_filter($where, $args) {
if(isset($args['year'])) {
$where .= ' AND YEAR(post_date) = ' . intval($args['year']);
}
return $where;
}
add_filter('getarchives_where', 'newmarket_getarchives_filter', 10, 2);
```
The CSS code:
```
.tree-accordion {
line-height: 1.5;
}
.tree-accordion dt, .tree-accordion dd {}
.tree-accordion dt a {
display: block;
}
.tree-accordion .fa {
color: #666666;
}
.tree-accordion dd a {}
.tree-accordion dd span {
display: block;
}
.tree-accordion dd {
margin: 0 0 0 20px;
}
```
The Javascript code:
```
jQuery(document).ready(function(){
var allPanels = jQuery('.tree-accordion > dd').hide();
jQuery('.tree-accordion > dt > a').click(function() {
$target = jQuery(this).parent().next();
if(!$target.hasClass('active')) {
allPanels.removeClass('active').slideUp();
$target.addClass('active').slideDown(100);
}
return false;
});
jQuery('.tree-accordion-empty').prev().hide();
});
```
**UPDATE:** Remove year after month:
Change this line:
```
$link = str_replace(array('<li>', "\n", "\t", "\s"), '' , $link);
```
To:
```
$link = str_replace(array('<li>', "\n", "\t", "\s"), '', $link);
$link = str_replace($year, '', $link);
```
The final result:

You can change the classes of the `<ul>` by adding `'menu_class'=>'nav navbar-nav'` to your `$args` array. *Remember, this parameter overwrites all the classes, so add "menu" as well if you want many themes and plugins to work!*
If you don't want the outer `<div>`, you can "unwrap" the `<ul>` by adding `'container'=>false`.
```
$args = array(
'theme_location' => 'primary',
'menu_class' => 'nav navbar-nav',
'container' => false,
);
```

You do need to run a custom query for your second loop. You can simply adjust the main query to your needs. It is always never a good idea to run custom queries in place of the main query. One big issue is always pagination, WordPress disregards all other queries, and only focus on the main query when it comes to page functionality. I have done a quite extensive post on this, so be sure to check it out [here](https://wordpress.stackexchange.com/a/155976/31545)
We can drop the second query, and just use `pre_get_posts` to alter the main query. Because we use offset here, we need to manually calculate pagination as we are breaking `WP_Query`'s process which calculates pagination
```
add_action( 'pre_get_posts', function ( $q )
{
if ( $q->is_home() // Only target the home page
&& $q->is_main_query() // Only target the main query
) {
// Get the current page number
$current_page = get_query_var( 'paged', 1 );
// Set offset
$offset = 3;
// Set posts per page
$ppp = 2;
if ( !$q->is_paged() ) {
// Set page one offset
$q->set( 'offset', $offset );
$q->set( 'posts_per_page', $ppp );
} else {
// Handle pagination for paged pages
$offset = $offset + ( ( $current_page - 1 ) * $ppp );
$q->set( 'offset', $offset );
$q->set( 'posts_per_page', $ppp );
}
}
});
```
You should now have your main query correctly paginated with one problem, the last page might, depending on the amount of posts, 404'ing. To adjust for that, we need to adjust the `$found_posts` property of the main query.
```
add_filter( 'found_posts', function ( $found_posts, $q )
{
$offset = 3;
if( $q->is_home()
&& $q->is_main_query()
) {
$found_posts = $found_posts - $offset;
}
return $found_posts;
}, 10, 2 );
```
Needless to say, your main loop on your homepage should now just be as follow
```
if ( have_posts() ) :
while ( have_posts()) :
the_post();
get_template_part( 'template-parts/content-rest', get_post_format() );
endwhile;
previous_posts_link();
next_posts_link();
endif;
```

We can drop the second query, and just use `pre_get_posts` to alter the main query. Because we use offset here, we need to manually calculate pagination as we are breaking `WP_Query`'s process which calculates pagination
```
add_action( 'pre_get_posts', function ( $q )
{
if ( $q->is_home() // Only target the home page
&& $q->is_main_query() // Only target the main query
) {
// Get the current page number
$current_page = get_query_var( 'paged', 1 );
// Set offset
$offset = 3;
// Set posts per page
$ppp = 2;
if ( !$q->is_paged() ) {
// Set page one offset
$q->set( 'offset', $offset );
$q->set( 'posts_per_page', $ppp );
} else {
// Handle pagination for paged pages
$offset = $offset + ( ( $current_page - 1 ) * $ppp );
$q->set( 'offset', $offset );
$q->set( 'posts_per_page', $ppp );
}
}
});
```
You should now have your main query correctly paginated with one problem, the last page might, depending on the amount of posts, 404'ing. To adjust for that, we need to adjust the `$found_posts` property of the main query.
```
add_filter( 'found_posts', function ( $found_posts, $q )
{
$offset = 3;
if( $q->is_home()
&& $q->is_main_query()
) {
$found_posts = $found_posts - $offset;
}
return $found_posts;
}, 10, 2 );
```
Needless to say, your main loop on your homepage should now just be as follow
```
if ( have_posts() ) :
while ( have_posts()) :
the_post();
get_template_part( 'template-parts/content-rest', get_post_format() );
endwhile;
previous_posts_link();
next_posts_link();
endif;
```

<p>I have an admin form for a plugin I am making. However, there are a couple of fields I need to add where the admin need to upload a document or image. When these files are uploaded, I do not want them to be added to the media library of WordPress as these files won't be used on any web pages. All I need is just the URL of where the file has been uploaded to on the server to use in the database. </p>
<p>What would be the best way to achieve this?</p>
<p>Thanks for your time!</p>

HTML
====
Okay, you'll of course want to set up an HTML file. I would use this code or something like it:
```
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
```
Of course, you don't have to use `upload.php` as your filename, that's just what w3schools used.
PHP
===
```
<?php
$target_dir = "your/file/upload/path";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
?>
```
Change `$target_dir` to whatever directory you want the files to go into and there you go. There are of course many jQuery plugins to do this in a fancy or pretty way but this is the basics using jQuery.

have you tried by setting the second argument of `wp_signon()` to `true` or blank?
set false will prevent `wp_signon()` from setting secure cookie which is essential for accessing `wp-admin` if your using ssl.
i have tested and `$user = wp_signon( $user_data, true );` works as expected.

<p>I would like to version control my WP sites with git. A big struggle I have with this is: how do you version control options/plugin settings in the database.</p>
<p>I would like to don't touch the dashboard in the live site. Only the users should need to login in to write posts - but I as a developer would like to log in only to check if everything is working on the live machine. Is there a way to do this?</p>
<p>I know that Drupal 8 has a build in configuration management - that's their solution. I also know "versionpress" and similar plugins. But they also version control the posts/pages/users etc. I don't need this. Example:</p>
<pre><code>Update option 'site_url' to 'http://example.com';
Reset update option 'site_url' to 'http://noexample.com';```
</code></pre>
<p>(the second line is to redo this step)</p>
<p>I guess there are some things in ruby on rails or similar. Would be great to separate code/options/settings and content/media/user-generated-stuff.</p>

[WP-CFM](https://wordpress.org/plugins/wp-cfm/) is probably the closest to what you're looking for. Actually, it has been inspired by Drupal's Features module.
From the plugin page:

However, as someone who has spent the better part of the past few years working on the versioning solution for WordPress (I'm a co-creator of VersionPress), I can say that it's tricky to version-control only parts of the site.

<p>I wish to create different template pages for all Parent Categories and Subcategories. I was hoping to do it using the hierarchy (eg. something like <code>category-parent.php</code> and <code>category-sub.php</code>), but looking at the flow diagram I found, I don't think there's an option:</p>
<p><a href="https://i.stack.imgur.com/GbVPA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GbVPA.png" alt="enter image description here"></a></p>
<p>I could manually add a <code>category-$slug.php</code> for the parent categories (as these shouldn't be changing) and then just use <code>category.php</code> for everything else (ie. the subcategories), but is there a better way?</p>

I wish to create different template pages for all Parent Categories and Subcategories. I was hoping to do it using the hierarchy (eg. something like `category-parent.php` and `category-sub.php`), but looking at the flow diagram I found, I don't think there's an option:
[](https://i.stack.imgur.com/GbVPA.png)
I could manually add a `category-$slug.php` for the parent categories (as these shouldn't be changing) and then just use `category.php` for everything else (ie. the subcategories), but is there a better way?

You can do this using custom template and [`template_include`](https://codex.wordpress.org/Plugin_API/Filter_Reference/template_include) filter.
`category-parent.php` and `category-sub.php` both are not required. One can be `category.php` for parent categories and for child categories, you can use `custom-category-child.php` as `category-sub.php` is reserved for default hierarchy.
* First create a template file in theme `custom-category-child.php`
* Then add this code to your theme `functions.php`
**Update**: As Pieter suggested we can use `category_template` instead of `template_include` to save few lines. Additionally we should return current template when our custom template file is missing!
**Read inline comments**
```
add_filter('category_template', 'custom_cat_templates');
/**
* Create custom template for child categroies
* @param type $template
* @return type
*/
function custom_cat_templates($template) {
$category = get_category(get_queried_object_id()); //Get the ID for current queried category
if ( $category->category_parent > 0 ) { //Check if it child category
$sub_category_template = locate_template('custom-category-child.php'); //return our custom template
$template = !empty($sub_category_template) ? $sub_category_template : $template; //return default template if custom templaet missing
}
return $template;
}
```

<p>I'm getting quite frustrated setting up the correct URL structure for a Cutom Post Type with a Custom taxonomy. </p>
<p>I have a Custom Post Type called <code>courses</code> with a Custom Taxonomy called <code>course-type</code>. </p>
<ol>
<li><strong>The URL structure should be:</strong>
<code>site.com/courses/course-type/course-single-post/</code>. </li>
<li><strong>For example:</strong> <code>site.com/courses/science/rocket-to-the-moon/</code></li>
</ol>
<p>I've managed to achieve that however not all URL parts are behaving as it should.</p>
<ul>
<li><code>site.com/courses/</code> - returns a 404</li>
<li><code>site.com/courses/science/</code> - Shows an archive page with all posts in
side that custom taxonomy which is correct</li>
<li><code>site.com/courses/science/rocket-to-the-moon/</code> - Shows the single Custom Post Type which is correct too</li>
</ul>

I'm getting quite frustrated setting up the correct URL structure for a Cutom Post Type with a Custom taxonomy.
I have a Custom Post Type called `courses` with a Custom Taxonomy called `course-type`.
1. **The URL structure should be:**
`site.com/courses/course-type/course-single-post/`.
2. **For example:** `site.com/courses/science/rocket-to-the-moon/`
I've managed to achieve that however not all URL parts are behaving as it should.
* `site.com/courses/` - returns a 404
* `site.com/courses/science/` - Shows an archive page with all posts in
side that custom taxonomy which is correct
* `site.com/courses/science/rocket-to-the-moon/` - Shows the single Custom Post Type which is correct too
I don't know why the `site.com/courses/` returns a 404 instead of showing an archive page listing all Custom Post Type's...?
**This is the code that I've used:**
```
<?php
/*Courses Custom Post Type*/
function my_custom_post_courses() {
$labels = array(
'name' => _x( 'Courses', 'post type general name' ),

Setting `has_archive` to `true` causes WordPress to generate a rewrite rule for the archive using the rewrite slug, which is not what you want in your case. Instead, explicitly specify the archive slug as a string and the correct rules will be generated:
```
$args = array(
'has_archive' => 'courses',
'rewrite' => array('slug' => 'courses/%course-type%','with_front' => false),
// the rest of your args...
);
register_post_type( 'courses', $args );
```

Till today I never used `header.php` and `footer.php` because my theme has multiple templates and I do not know how or where to place the CSS and JS files. Could someone please explain how to have a `header.php` and use `get_header();` but also include new CSS files depending on the template?
**Normal Code** *And how I see it*
```
<?php /* Template Name: Contact Template */ ?>
<!-- HERE STARTS HEADER PHP? -->
<!DOCTYPE html>
<html>
<head>
<title>Website</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<?php wp_head(); ?>
</head>
<body>
<header>
<!-- MENU AND STUFF -->
</header>
<main>
<!-- HERE STOPS HEADER PHP ? -->
<!-- SOME CONTENT -->
<!-- HERE STARTS FOOTER PHP? -->
</main>
<footer>
<!-- SOME CONTENT -->
</footer>
<!-- HERE I PLACE MY JS FILES -->
</body>
</html>
<!-- HERE STOPS FOOTER PHP? -->
```
As you can see, where I place my CSS and JS files are in the `header.php` or `footer.php` so I can not add more depending on the template. How do you add CSS files if you use multiple templates?
===================================================
**Problem is almost solved. Just need to create an if/else statement to check the `Template Name:`.**
|
Include CSS and JavaScipt in the `functions.php`.
Create an empty PHP file, call it `header.php`, and yes `wp_head()` goes just before `</head>` not before `<body>` tag.
```
<!DOCTYPE html>
<html>
<head>
<title>Website</title>
<link href="style.css" rel="stylesheet" type="text/css" />
<?php wp_head(); ?>
</head>
```
Create an empty PHP file, call it `footer.php` and place your footer there:
```
<footer>
<!-- SOME CONTENT -->
</footer>
<!-- HERE I PLACE MY JS FILES -->
</body>
</html>
```
In `functions.php`:
```
function my_scripts_styles() {
wp_enqueue_script('jquery_flexslider_js', get_template_directory_uri() . '/js/jquery.flexslider.min.js', array('jquery'),'3.0.0', true );
wp_enqueue_style('flexslider_css', get_template_directory_uri() . '/css/flexslider.css', false ,'3.0.0');
}
add_action('wp_enqueue_scripts', 'my_scripts_styles');
```
With [`wp_enqueue_script()`](https://developer.wordpress.org/reference/functions/wp_enqueue_script/) add JavaScript, the last argument `true` means it will be placed at the bottom. You need to give it a unique name e.g. `flexslider_js_my`. Include as many js files as you need.
With [`wp_enqueue_style()`](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) you add CSS files. The last argument `false` means it will be placed in the header. Give it a unique name, include as many as you need.
The rest of your code stays in `index.php`. `header.php`, `footer.php`, `functions.php` they are all in the home directory where your `index.php` is.
`index.php`:
```
<?php get_header(); ?>
<body>
<header>
<!-- MENU AND STUFF -->
</header>
<main>
<!-- HERE STOPS HEADER PHP ? -->
<!-- SOME CONTENT -->
<!-- HERE STARTS FOOTER PHP? -->
</main>
<footer>
<!-- SOME CONTENT -->
</footer>
<!-- HERE I PLACE MY JS FILES -->
</body>
<?php get_footer(); ?>
```
Btw, in your case you don't need to include `<?php /* Template Name: Contact Template */ ?>` at the top. You can do just like in my example.
Update, the template name:
In my case [`get_page_template()`](https://developer.wordpress.org/reference/functions/get_page_template/) will output the whole template path for example:
>
> /homepages/133/htdocs/dd/myheme/wp-content/themes/authentic/page.php
>
>
>
where 'authentic' is my template name. So the *if* construct to include in `functions.php`:
```
$url = get_page_template();
$parts = explode('/', $url);
$name = $parts[count($parts) - 2];
if('authentic' == $name) {
wp_enqueue_style('homeCSS', get_template_directory_uri() . '/css/home.css', false ,'3.0.0');
}

<p>I have a custom post type called <code>shows</code> and taxonomy called <code>podcast</code>. Using <code>taxonomy-podcast.php</code>, I having hard time finding a function that will generate next/previous Term URL Archive.</p>
<h2>For Example:</h2>
<p>URL: url.com/podcast/example-term-2</p>
<blockquote>
<p><strong>Example Term 2</strong></p>
<p>post 1,post 2,post 3</p>
</blockquote>
<p>Desired output</p>
<pre><code>< Previous Term(url.com/podcast/example-term-1) . . . . . | . . . . . Next Term(url.com/podcast/example-term-3)>
</code></pre>

I have a custom post type called `shows` and taxonomy called `podcast`. Using `taxonomy-podcast.php`, I having hard time finding a function that will generate next/previous Term URL Archive.
For Example:
------------
URL: url.com/podcast/example-term-2
>
> **Example Term 2**
>
>
> post 1,post 2,post 3
>
>
>
Desired output
```
< Previous Term(url.com/podcast/example-term-1) . . . . . | . . . . . Next Term(url.com/podcast/example-term-3)>
```
|
It is quite possible to achieve this. What we need to do is
* Get all the terms sorted by slug (*or any other field desired*) associated with our taxonomy
* Get the current term object
* Determine where in the array our current term is
* Get the two adjacent terms (*if any*)
* Build the links to those term pages
THE FUNCTION
------------
I have written a function to take care of this. It ids always important to keep business logic out of templates. Templates should only know function names and not the entire function. This way, you keep your templates clean and maintainable
The function does require a minimum of PHP 5.4 and covers the basics, it is up to you to adjust it to your needs
```
function get_tax_navigation( $taxonomy = 'category' )
{
// Make sure we are on a taxonomy term/category/tag archive page, if not, bail
if ( 'category' === $taxonomy ) {
if ( !is_category() )
return false;
} elseif ( 'post_tag' === $taxonomy ) {
if ( !is_tag() )
return false;
} else {
if ( !is_tax( $taxonomy ) )
return false;
}
// Make sure the taxonomy is valid and sanitize the taxonomy
if ( 'category' !== $taxonomy
|| 'post_tag' !== $taxonomy
) {
$taxonomy = filter_var( $taxonomy, FILTER_SANITIZE_STRING );
if ( !$taxonomy )
return false;
if ( !taxonomy_exists( $taxonomy ) )
return false;
}
// Get the current term object
$current_term = get_term( $GLOBALS['wp_the_query']->get_queried_object() );
// Get all the terms ordered by slug
$terms = get_terms( $taxonomy, ['orderby' => 'slug'] );
// Make sure we have terms before we continue
if ( !$terms )
return false;
// Because empty terms stuffs around with array keys, lets reset them
$terms = array_values( $terms );
// Lets get all the term id's from the array of term objects
$term_ids = wp_list_pluck( $terms, 'term_id' );
/**
* We now need to locate the position of the current term amongs the $term_ids array. \
* This way, we can now know which terms are adjacent to the current one
*/
$current_term_position = array_search( $current_term->term_id, $term_ids );
// Set default variables to hold the next and previous terms
$previous_term = '';
$next_term = '';
// Get the previous term
if ( 0 !== $current_term_position )
$previous_term = $terms[$current_term_position - 1];
// Get the next term
if ( intval( count( $term_ids ) - 1 ) !== $current_term_position )
$next_term = $terms[$current_term_position + 1];
$link = [];
// Build the links
if ( $previous_term )
$link[] = 'Previous Term: <a href="' . esc_url( get_term_link( $previous_term ) ) . '">' . $previous_term->name . '</a>';
if ( $next_term )
$link[] = 'Next Term: <a href="' . esc_url( get_term_link( $next_term ) ) . '">' . $next_term->name . '</a>';
return implode( ' ...|... ', $link );
}
```
USAGE
-----
You can now just use the function where needed as follow:
```
echo get_tax_navigation( 'podcast' );
```
EDIT - from comments
--------------------
>
> Just two questions: (1)When we are at the last term, can we still make the Next Term: (URL to the First term) and vise versa? Basically an infinite term loop. (2)For theming purposes, how can I use this function to output NEXT and PREVIOUS urls individually? (eg. get\_tax\_navigation( 'podcast', 'previous' ) and get\_tax\_navigation( 'podcast', 'next' )

1. When we are on the last of first term, all we need to do is either grab the first or last term depending on where we at. Obviously, when we are on the laste term, we will grab the first one, and vica-versa
2. We can introduce a `$direction` parameter which accepts three values, an empty string, `previous` or `next`
Here is an example of what you can do. You can adjust it from here to suite your needs
```
function get_tax_navigation( $taxonomy = 'category', $direction = '' )
{
// Make sure we are on a taxonomy term/category/tag archive page, if not, bail
if ( 'category' === $taxonomy ) {
if ( !is_category() )
return false;
} elseif ( 'post_tag' === $taxonomy ) {
if ( !is_tag() )
return false;
} else {
if ( !is_tax( $taxonomy ) )
return false;
}
// Make sure the taxonomy is valid and sanitize the taxonomy
if ( 'category' !== $taxonomy
|| 'post_tag' !== $taxonomy
) {
$taxonomy = filter_var( $taxonomy, FILTER_SANITIZE_STRING );
if ( !$taxonomy )
return false;
if ( !taxonomy_exists( $taxonomy ) )
return false;
}
// Get the current term object
$current_term = get_term( $GLOBALS['wp_the_query']->get_queried_object() );
// Get all the terms ordered by slug
$terms = get_terms( $taxonomy, ['orderby' => 'slug'] );
// Make sure we have terms before we continue
if ( !$terms )
return false;
// Because empty terms stuffs around with array keys, lets reset them
$terms = array_values( $terms );
// Lets get all the term id's from the array of term objects
$term_ids = wp_list_pluck( $terms, 'term_id' );
/**
* We now need to locate the position of the current term amongs the $term_ids array. \
* This way, we can now know which terms are adjacent to the current one
*/
$current_term_position = array_search( $current_term->term_id, $term_ids );
// Set default variables to hold the next and previous terms
$previous_term = '';
$next_term = '';
// Get the previous term
if ( 'previous' === $direction
|| !$direction
) {
if ( 0 === $current_term_position ) {
$previous_term = $terms[intval( count( $term_ids ) - 1 )];
} else {
$previous_term = $terms[$current_term_position - 1];
}
}
// Get the next term
if ( 'next' === $direction
|| !$direction
) {
if ( intval( count( $term_ids ) - 1 ) === $current_term_position ) {
$next_term = $terms[0];
} else {
$next_term = $terms[$current_term_position + 1];
}
}
$link = [];
// Build the links
if ( $previous_term )
$link[] = 'Previous Term: <a href="' . esc_url( get_term_link( $previous_term ) ) . '">' . $previous_term->name . '</a>';
if ( $next_term )
$link[] = 'Next Term: <a href="' . esc_url( get_term_link( $next_term ) ) . '">' . $next_term->name . '</a>';
return implode( ' ...|... ', $link );
}
```
You can use the code in three different ways
* `echo get_tax_navigation( 'podcast' );` to display next and previous terms
* `echo get_tax_navigation( 'podcast', 'previous' );` to display only the previous term
* `echo get_tax_navigation( 'podcast', 'next' );` to display only the next term

<p>How can I apply this function to a single page ID:</p>
<pre><code>function exclude_jobs_locations($args){
$exclude = "40";
$args["exclude"] = $exclude;
return $args;
}
add_filter("sjb_job_location_filter_args","exclude_jobs_locations");
</code></pre>
<p>Can I also exclude child categories when parent category is excluded?</p>
<p>I've tried with:</p>
<pre><code>function exclude_jobs_locations_uk($args){
if( is_page( 2094 ) ) {
$exclude = "40";
$args["exclude"] = $exclude;
}
return $args;
}
add_filter("sjb_job_location_filter_args","exclude_jobs_locations_uk");
</code></pre>
<p>But something goes wrong.</p>
<p>I use this function to exclude category from:</p>
<pre><code>// Creating list on non-empty job location
$jobloc_select = wp_dropdown_categories(apply_filters('sjb_job_location_filter_args', array(
'show_option_none' => __('Location', 'simple-job-board'),
'hide_empty' => 0,
'name' => 'selected_location',
'orderby' => 'NAME',
'order' => 'ASC',
'class' => 'sjb-form-control',
'hierarchical' => TRUE,
'value_field' => 'slug',
'taxonomy' => 'jobpost_location',
'selected' => $selected_location,
'echo' => FALSE,
)));
?>
</code></pre>

How can I apply this function to a single page ID:
```
function exclude_jobs_locations($args){
$exclude = "40";
$args["exclude"] = $exclude;
return $args;
}
add_filter("sjb_job_location_filter_args","exclude_jobs_locations");
```
Can I also exclude child categories when parent category is excluded?
I've tried with:
```
function exclude_jobs_locations_uk($args){
if( is_page( 2094 ) ) {
$exclude = "40";
$args["exclude"] = $exclude;
}
return $args;
}
add_filter("sjb_job_location_filter_args","exclude_jobs_locations_uk");
```
But something goes wrong.
I use this function to exclude category from:
```
// Creating list on non-empty job location
$jobloc_select = wp_dropdown_categories(apply_filters('sjb_job_location_filter_args', array(
'show_option_none' => __('Location', 'simple-job-board'),
'hide_empty' => 0,
'name' => 'selected_location',
'orderby' => 'NAME',
'order' => 'ASC',
'class' => 'sjb-form-control',
'hierarchical' => TRUE,
'value_field' => 'slug',
'taxonomy' => 'jobpost_location',
'selected' => $selected_location,
'echo' => FALSE,
)));
?>
```
|
It is quite possible to achieve this. What we need to do is
* Get all the terms sorted by slug (*or any other field desired*) associated with our taxonomy
* Get the current term object
* Determine where in the array our current term is
* Get the two adjacent terms (*if any*)
* Build the links to those term pages
THE FUNCTION
------------
I have written a function to take care of this. It ids always important to keep business logic out of templates. Templates should only know function names and not the entire function. This way, you keep your templates clean and maintainable
The function does require a minimum of PHP 5.4 and covers the basics, it is up to you to adjust it to your needs
```
function get_tax_navigation( $taxonomy = 'category' )
{
// Make sure we are on a taxonomy term/category/tag archive page, if not, bail
if ( 'category' === $taxonomy ) {
if ( !is_category() )
return false;
} elseif ( 'post_tag' === $taxonomy ) {
if ( !is_tag() )
return false;
} else {
if ( !is_tax( $taxonomy ) )
return false;
}
// Make sure the taxonomy is valid and sanitize the taxonomy
if ( 'category' !== $taxonomy
|| 'post_tag' !== $taxonomy
) {
$taxonomy = filter_var( $taxonomy, FILTER_SANITIZE_STRING );
if ( !$taxonomy )
return false;
if ( !taxonomy_exists( $taxonomy ) )
return false;
}
// Get the current term object
$current_term = get_term( $GLOBALS['wp_the_query']->get_queried_object() );
// Get all the terms ordered by slug
$terms = get_terms( $taxonomy, ['orderby' => 'slug'] );
// Make sure we have terms before we continue
if ( !$terms )
return false;
// Because empty terms stuffs around with array keys, lets reset them
$terms = array_values( $terms );
// Lets get all the term id's from the array of term objects
$term_ids = wp_list_pluck( $terms, 'term_id' );
/**
* We now need to locate the position of the current term amongs the $term_ids array. \
* This way, we can now know which terms are adjacent to the current one
*/
$current_term_position = array_search( $current_term->term_id, $term_ids );
// Set default variables to hold the next and previous terms
$previous_term = '';
$next_term = '';
// Get the previous term
if ( 0 !== $current_term_position )
$previous_term = $terms[$current_term_position - 1];
// Get the next term
if ( intval( count( $term_ids ) - 1 ) !== $current_term_position )
$next_term = $terms[$current_term_position + 1];
$link = [];
// Build the links
if ( $previous_term )
$link[] = 'Previous Term: <a href="' . esc_url( get_term_link( $previous_term ) ) . '">' . $previous_term->name . '</a>';
if ( $next_term )
$link[] = 'Next Term: <a href="' . esc_url( get_term_link( $next_term ) ) . '">' . $next_term->name . '</a>';
return implode( ' ...|... ', $link );
}
```
USAGE
-----
You can now just use the function where needed as follow:
```
echo get_tax_navigation( 'podcast' );
```
EDIT - from comments
--------------------
>
> Just two questions: (1)When we are at the last term, can we still make the Next Term: (URL to the First term) and vise versa? Basically an infinite term loop. (2)For theming purposes, how can I use this function to output NEXT and PREVIOUS urls individually? (eg. get\_tax\_navigation( 'podcast', 'previous' ) and get\_tax\_navigation( 'podcast', 'next' )
>
>
>
1. When we are on the last of first term, all we need to do is either grab the first or last term depending on where we at. Obviously, when we are on the laste term, we will grab the first one, and vica-versa
2. We can introduce a `$direction` parameter which accepts three values, an empty string, `previous` or `next`
Here is an example of what you can do. You can adjust it from here to suite your needs
```
function get_tax_navigation( $taxonomy = 'category', $direction = '' )
{
// Make sure we are on a taxonomy term/category/tag archive page, if not, bail
if ( 'category' === $taxonomy ) {
if ( !is_category() )
return false;
} elseif ( 'post_tag' === $taxonomy ) {
if ( !is_tag() )
return false;
} else {
if ( !is_tax( $taxonomy ) )
return false;
}
// Make sure the taxonomy is valid and sanitize the taxonomy
if ( 'category' !== $taxonomy
|| 'post_tag' !== $taxonomy
) {
$taxonomy = filter_var( $taxonomy, FILTER_SANITIZE_STRING );
if ( !$taxonomy )
return false;
if ( !taxonomy_exists( $taxonomy ) )
return false;
}
// Get the current term object
$current_term = get_term( $GLOBALS['wp_the_query']->get_queried_object() );
// Get all the terms ordered by slug
$terms = get_terms( $taxonomy, ['orderby' => 'slug'] );
// Make sure we have terms before we continue
if ( !$terms )
return false;
// Because empty terms stuffs around with array keys, lets reset them
$terms = array_values( $terms );
// Lets get all the term id's from the array of term objects
$term_ids = wp_list_pluck( $terms, 'term_id' );
/**
* We now need to locate the position of the current term amongs the $term_ids array. \
* This way, we can now know which terms are adjacent to the current one
*/
$current_term_position = array_search( $current_term->term_id, $term_ids );
// Set default variables to hold the next and previous terms
$previous_term = '';
$next_term = '';
// Get the previous term
if ( 'previous' === $direction
|| !$direction
) {
if ( 0 === $current_term_position ) {
$previous_term = $terms[intval( count( $term_ids ) - 1 )];
} else {
$previous_term = $terms[$current_term_position - 1];
}
}
// Get the next term
if ( 'next' === $direction
|| !$direction
) {
if ( intval( count( $term_ids ) - 1 ) === $current_term_position ) {
$next_term = $terms[0];
} else {
$next_term = $terms[$current_term_position + 1];
}
}
$link = [];
// Build the links
if ( $previous_term )
$link[] = 'Previous Term: <a href="' . esc_url( get_term_link( $previous_term ) ) . '">' . $previous_term->name . '</a>';
if ( $next_term )
$link[] = 'Next Term: <a href="' . esc_url( get_term_link( $next_term ) ) . '">' . $next_term->name . '</a>';
return implode( ' ...|... ', $link );
}
```
You can use the code in three different ways
* `echo get_tax_navigation( 'podcast' );` to display next and previous terms
* `echo get_tax_navigation( 'podcast', 'previous' );` to display only the previous term
* `echo get_tax_navigation( 'podcast', 'next' );` to display only the next term

Unfortunately there's nothing native in WordPress to handle searching and replacing your domain name across all your posts, options, etc.
The closest you can get is WP-CLI's [search-replace](http://wp-cli.org/commands/search-replace/) command. It's not an official WordPress project, but it has quite a high adoption rate, it's very well maintained and available by default or on demand on many hosting platforms:
```
wp search-replace 'http://old-site.org' 'http://new-site.org'
```
Another popular option is [this](https://interconnectit.com/products/search-and-replace-for-wordpress-databases/) database search and replace script which, just like WP-CLI, correctly handles serialized data, which is important for WordPress because many options and meta values are stored as serialized arrays.

<p>I am trying to build a simple Wordpress favourite post plugin that is scalable and could handle 1000s or 10000s of users or more.</p>
<p>There are several different approaches that I have seen in other plugins and I would like to know which would be best practice from a scalability point of view, which means that size of the record or the number of records could be an issue.</p>
<p>Problem: The basic idea is that there is a button on a post that a logged in user can click to favourite the post. This must then be stored in the database so that when the user goes to that post, they cannot favourite it again and also they can view a list of their favourited posts.</p>
<p><strong>Option 1: Store in both user meta and post meta tables with serialised arrays</strong></p>
<p>This is what the Wordpress Post Like System (<a href="https://hofmannsven.com/2013/laboratory/wordpress-post-like-system/" rel="nofollow">https://hofmannsven.com/2013/laboratory/wordpress-post-like-system/</a>) does. Following the click, the code retrieves _liked_posts meta key from the user meta table that stores in an array the post ids of the posts that the user has liked and it retrieves the _user_likes meta key from the post meta table that stores in an array the user ids of the users that have liked the post.</p>
<p>The code then appends the current post id to the _liked_posts and the current user id to _user_likes. It also increments two further meta records: post like count and a user like count.</p>
<p>What I like about this system is that it seems fairly simple, with only one record in user meta and one record in post meta storing who has liked what. What I don't like is that if you have many users liking the post or a user that likes many posts those meta value arrays could get very long, which I assume could cause problems?</p>
<pre><code>$meta_POSTS = get_user_meta( $user_id, "_liked_posts" ); // post ids from user meta
$meta_USERS = get_post_meta( $post_id, "_user_liked" ); // user ids from post meta
$meta_POSTS['post-'.$post_id] = $post_id; // Add post id to user meta array
$meta_USERS['user-'.$user_id] = $user_id; // add user id to post meta array
update_post_meta( $post_id, "_user_liked", $meta_USERS ); // Add user ID to post meta
update_user_meta( $user_id, "_liked_posts", $meta_POSTS ); // Add post ID to user meta
</code></pre>
<p><strong>Option 2: Add a record to user meta for each liked post</strong></p>
<p>Following the click, the code checks if a record has already been inserted into user meta. If not, it adds a new record of the favourite. If it has, it does nothing.</p>
<p>What I like about this system, is it is easy to query and generate statistics down the road as it is not tied up in serialised arrays. What I don't like is that if you have the user liking lots of posts you could hugely increase the number of records in the user meta table.</p>
<pre><code>// Check if already favourited the post in User Meta
// Not sure how you would do this with WP_Query or WP_User_Query, any suggestions?
$favourited = WP_Query($args)
if ($favourited->post_count == 0) {
// Add user meta with favourite
add_user_meta($userid, '_favourite_episode', $postid);
}
</code></pre>
<p>So to conclude, what I am asking essentially is what is best practice here. Is it either:</p>
<ul>
<li>Having one large serialised array in a single meta key/value pair</li>
<li>Having many meta/key value pairs with an integer in the meta value</li>
<li>Is there another option I haven't considered?</li>
</ul>
<p><strong>EDIT:</strong> Following the answers given, I have decided that creating a custom table is the best way forward. I have found this tutorial that does pretty much what I want to do and in a much more extendable way so that I can add other actions as well as just 'favouriting'.</p>

You forgot option 3 - Add a special table in which the pair (user,post id) will be the index. Ok I am not a MySQL person so maybe it is too extreme, but maybe having two tables one with users as index and one with posts will be even better.
The thing about performance is that there are rarely absolute solutions for everybody at anytime, and the "best" depends on your actual usage pattern, not the theoretical one. Or in other words, you are doing early optimization here.
While option 2 seems to be faster for this specific information it will make the meta tables bigger and therefor is likely to slow down **all** requests to those tables (therefor the suggestion for option 3 which is very similar but do not impact other queries).

If you are going to have many likes at the same time, with option 2 you will lock the tables and requests will need to wait for others to complete and each insert will be slower while option 1 is likely to end in data corruption under naive implementation (two changes in the same time, at best only one of them will have impact).
And then you should take into account what kind of caching will you do. With a good caching scheme the read time is a non issue.
To conclude I wish that you will find this to be an actual problem that needs to be solved, till then just write proper api to access/change that data to hide the implementation detail so if it will become a problem you will be able to change the implementation without impacting the rest of your code.

<p>On a fresh install, I want to move the upload folder to a subdomain (supposed to speed up download). My subdomain links to a folder called static. So I have: </p>
<ul>
<li>Home
<ul>
<li>wp
<ul>
<li>wp-admin</li>
<li>wp-content</li>
<li>wp-include</li>
</ul></li>
<li>static</li>
</ul></li>
</ul>
<p>Now I need to tell WordPress where the upload folder is and define its URL. The <a href="http://codex.wordpress.org/Editing_wp-config.php#Moving_uploads_folder" rel="noreferrer">codex</a> says I should edit wp-config to define UPLOADS relative to ABSPAHT. But if I put <code>define( 'UPLOADS', '../static' );</code> of course URL in pages are like <code>//mydomain.tld/wp/../static/image.jpg</code> </p>
<p>I've looked around, and found many different answers to that (filters, DB edit,...), some of them no longer true (since the media settings page no longer allows to change the upload folder) and some obviously wrong... I want to do it the right way.</p>
<p>I went to the wp-admin/options.php page and set <code>upload_path = ../static</code> and <code>upload_url_path = http://static.mydomain.tld</code> and that seems to work. </p>
<p><strong>But is that how it's supposed to be done?</strong>
And if developpers have removed these options from the media settings page, isn't there a risk that the feature is later completely removed? </p>

Nope. You should never change anything in the WordPress core files because all your changes will be lost during the next update. You should use actions and filters instead:
```
add_filter( 'pre_option_upload_path', function( $upload_path ) {
return '/path/to/static';
});
add_filter( 'pre_option_upload_url_path', function( $upload_url_path ) {
return 'http://static.example.org';
});

You can use [`get_terms()`](https://developer.wordpress.org/reference/functions/get_terms/) to retrieve the custom taxonomy terms and then build up a custom array to match the structure you want.
Try this:
```
//Get the custom taxonomy terms
$taxonomies = array(
'name' => 'your_custom_taxonomy' //Edit to match your needs
);
$taxonomy_terms = get_terms( $taxonomies );
//This array will store the results
$taxonomy_array = array();
//Parse the terms
foreach ( $taxonomy_terms as $taxonomy_term ) :
//Get the taxonomy term name
$taxonomy_term_name = $taxonomy_term->name;
//Get the taxonomy term slug
$taxonomy_term_slug = $taxonomy_term->slug;
//Push the custom array
$taxonomy_array[ $taxonomy_term_name ] = $taxonomy_term_slug;
endforeach;
```
The data will be stored in `$taxonomy_array` following the format you provided. You can pass additional arguments to `get_terms()`, such as the order.

I have two different files for the header in my theme. These are `header.php` and `header-full.php`.
How can I load different CSS in different headers?
I enqueue my CSS files in `function.php` like this:
[](https://i.stack.imgur.com/HE8U6.jpg)
|
Enqueue style depending on a template filename:
```
if('header.php' == basename( get_page_template() ) { // check the template file name
// enqueue header.php style here
}
if('header-full.php' == basename( get_page_template() ) { // check the template file name
// enqueue header-full.php style here
}
```
`wp_enqueue_style` already registers a style so you don't need to register a style before enqueueing it except in very special cases. See [wp\_enqueue\_style](https://developer.wordpress.org/reference/functions/wp_enqueue_style/).

* You can try minify html from the contact form 7
* To completely disable the wpautop filter, you can use:
```
remove_filter('the_content', 'wpautop');

I want that `the_content` and `wp_head` only load if the page is active.
If you need more information please tell me.
Thanks.

It's a common mistake about the difference of WordPress' Actions and Filters.
1. Action is when you want something to happens besides the default.
2. Filter is when you want something to happens instead the default.
Knowing that, when you use an action, your output will be inserted in that action content. But when you use a filter, your output will replace that filter content.
In the filter `the_content` you are replacing all the content from a post with your plugin content. So, the right way to fix it would be appending your content to the output, like `$content .= "<div>...</div>";`

<p>I do not have the greatest CSS skills in the world, but I can normally figure things out. Right now I'm trying to implement a fairly simple media query in the child theme of my Wordpress site. I don't know if I typed something wrong or made another mistake, but the media query rules don't even show up when I inspect my page. Can anyone help?</p>
<p>This is the page: <a href="http://www.thousandgirlsinitiative.org/" rel="nofollow">http://www.thousandgirlsinitiative.org/</a></p>
<p>And these are the rules that I've tried to implement:</p>
<pre><code>@media screen and (max-device-width: 479px) {
.sow-slider-base ul.sow-slider-images li.sow-slider-image.sow-slider-image-cover {
background-image:url ("http://www.thousandgirlsinitiative.org/wp-content/uploads/2016/04/Wendy-mobile.jpg") !important; }
#why-sponsor-homepage { padding: 20px; }
}
</code></pre>
<p>Basically I want to use a different hero image in the top row and decrease the padding on the "Why Sponsor?" row when the screen is narrower than 480px. </p>
<p>I had written the query with "max-width" instead of "max-device-width" at first and it didn't work either, so that is not the problem.</p>
<p>Any help would be very appreciated!</p>

all -

I don't know if I typed something wrong or made another mistake, but the media query rules don't even show up when I inspect my page. Can anyone help?
This is the page: <http://www.thousandgirlsinitiative.org/>
And these are the rules that I've tried to implement:

```
Basically I want to use a different hero image in the top row and decrease the padding on the "Why Sponsor?" row when the screen is narrower than 480px.
I had written the query with "max-width" instead of "max-device-width" at first and it didn't work either, so that is not the problem.

I think I may have the solution below :)
Try adding this to your CSS file:
```
@media screen and (max-width: 479px) {
.sow-slider-base ul.sow-slider-images li.sow-slider-image.sow-slider-image-cover {
background-image: url('http://www.thousandgirlsinitiative.org/wp-content/uploads/2016/04/Wendy-mobile.jpg') !important;
}
#why-sponsor-homepage {
padding: 20px;
}
}
```
All I have done here is removed the space between `url` and the link of the image and it seems to work like a charm when I added the CSS via Google Developer Tool.

Just as @Jevuska mentioned, you can use the $post\_id as an argument here, in fact, you can also use a ton of optional $args as well `<?php comment_form( $args, $post_id ); ?>`
You can find the information in the Codex here: <https://codex.wordpress.org/Function_Reference/comment_form>

You are following a wrong format to call sub header file.
**Here is how we have to call sub header files:**
```
<?php get_header('subexample'); ?>
```
**Here is how you have to name the sub header file:**
`header-subexample.php`
Hope this helps!

<p>I'm having an issue with the order WordPress is loading page templates and <code>functions.php</code>.</p>
<p>I have <code>front-page.php</code> which has <code>$_POST['sort-by']</code> allowing users to sort posts using a drop-down menu.</p>
<p>It's simple enough and works just fine. Now comes the part where I have the ability to "Load more posts" which uses <code>wp_ajax</code> and <code>wp_ajax_nopriv</code> and a function in <code>functions.php</code> to grab the additional posts with an offset of the number of posts shown by default. My AJAX query works just fine, but I'm unable to grab the <code>$_POST</code> data from the <code>front-page.php</code> template within' <code>functions.php</code> to properly sort the posts fetched by the AJAX.</p>
<p>I thought it'd be as simple as just including my same <code>$_POST</code> values within' <code>functions.php</code> so it would use the proper sorting+meta_key, but no matter what I do including attempting to assign a separate variable to <code>$GLOBALS</code> containing the <code>$_POST</code>, I can not for the life of me get it to get the values set in <code>front-page.php</code> in <code>functions.php</code> so it will sort it properly when calling <code>wp_ajax</code> and <code>wp_ajax_nopriv</code>.</p>
<p>I'm assuming this has to do with <code>functions.php</code> being loaded BEFORE <code>front-page.php</code> within' WordPress. I'm not sure if there's an <code>add_action();</code> of some kind that would allow me to fix my issue here or how I should go about getting it to work as intended. I know it has to be possible though.</p>

<p>I am setting up an events page for my website. This page is using a loop to display a list of acts performing at different venues month-by-month. When a viewer comes to the page, they use a simple form to select the month, and when submitted this return the relevant data. At the moment the data fields I am displaying for each individual act in the loop are as follows:</p>
<ol>
<li>Event date (Advanced custom fields data picker)</li>
<li>Venue (Advanced custom fields text field)</li>
<li>Image of act (Advanced custom fields Image field)</li>
<li>Act Name (Advanced custom fields text field)</li>
<li>Description (Advanced custom fields text area field)</li>
</ol>
<p>You can view how this is working <a href="http://hru.websiteprime.co.uk/events/" rel="nofollow noreferrer">here</a></p>
<p>I need to change the layout so that when the list of events are returned it looks like this:<a href="https://i.stack.imgur.com/NbdEg.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NbdEg.jpg" alt="enter image description here"></a></p>
<p>So essentially I need the loop to pump out rows for each day of the month and if there is an act at a venue on the date, to include it in the row. if there is no act on the date then i can just be left blank( as illustrated above)</p>
<p>Thank you for your help in advance, and if you would like any further information, I will answer as best I can.</p>

Are there any disadvantages to using the following code to setup WP\_HOME and WP\_SITEURL in wp.config for both singlesite installs and multisite installs:
```
/**
* Site Host URLs
*/
$hostname = $_SERVER['HTTP_HOST'];
if(isset($_SERVER['HTTP_X_FORWARDED_HOST']) && !empty($_SERVER['HTTP_X_FORWARDED_HOST'])) {
$hostname = $_SERVER['HTTP_X_FORWARDED_HOST'];
}
$protocol = isset($_SERVER['HTTPS'])
&& ($_SERVER['HTTPS'] == 'on'
|| $_SERVER['HTTPS'] == 1)
|| isset($_SERVER['HTTP_X_FORWARDED_PROTO'])
&& $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'
? 'https://'
: 'http://';
$siteUrl = $protocol . rtrim($hostname, '/');
define('WP_HOME', $siteUrl);
define('WP_SITEURL', $siteUrl);
```

The obvious problem is that you are trusting user input (http headers) which makes your code suspicious from security POV.
Other then that, no real problems with it, but my experience is that such hacks have a tendency to just move whatever problem you are trying to solve this way to another place.

<p>I have built a site using WooCommerce Bookings with an AJAX request that processes the payment, creates and order and lastly creates a booking with the order ID.

I think you are looking for [plugin\_dir\_url](https://codex.wordpress.org/Function_Reference/plugin_dir_url):
```
$url = plugin_dir_url(__FILE__);
$imageurl = $url.'images/someimage.png';
```
**EDIT**: Sorry I misread the question... that is only an answer to the linked question. You could check the parent directory recursively until you find the right one:
```
function base_plugin_dir($dirpath) {
if (substr(dirname($dir),-7) == 'plugins') {return $dirpath;}
else {$dirpath = base_plugin_dir($dirpath);}
return $dirpath;
}
function base_plugin_dir_url($filepath) {
$baseplugindir = base_plugin_dir(dirname($filepath));
$url = plugin_dir_url(trailingslashit($baseplugindir));
return $url;
}
```
Then you can get the URL using that function from whatever file:
```
$basepluginurl = base_plugin_dir_url(__FILE__);
$imageurl = $basepluginurl.'/images/wordpress.png';
```
**OR**
Better yet just set a constant from your main plugin file to use it later:
```
$url = plugin_dir_url(__FILE__);
define('MY_UNIQUE_PLUGIN_URL',$url);
```
So as to use in say `/plugin/my-plugin/class/class1.php`
```
$imageurl = MY_UNIQUE_PLUGIN_URL.'/images/wordpress.png';
```

<p>Is there a way to get products in the order of the IDs in the shortcode parameter:</p>
<p>e.g <code>[products ids="53,68,1"]</code></p>
<p>Display block with 3 product, where 53 on first place, 68 on second...?</p>

<p>I want to show a select box for user roles in the registration form. I am using this model:</p>
<pre><code>/* ROLES IN LIST REGISTRATION */
// 1. Add a new form element...

echo '<option value="'.$key.'">'.$value['name'].'</option>';

}
// 2. Add validation.

function odin_registration_errors( $errors, $sanitized_user_login, $user_email ) {
if (

}
}
</code></pre>
<p>The point is that I have not seen the error happen when validation choose an empty option.</p>
<p>So what I alncançar is as follows:</p>
<p>1) Filter the types of users except the Administrator, Editor, Author, Contributor, and the Store Manager. I could just set the Subscriber and Customer functions, but the project must be free to create other roles without having to write the code again.</p>
<p>2) I need to validate the record of the options in this field, because it already has achieved filter rendering of roles in the selection list, we have to ensure that there is the possibility of u stranger inject an option in html with the value 'administrator' for example.

<p>I need the hint of you how I can do this.</p>

Then on scroll I load the next posts <em>(infinite scroll effect)</em>.

<p>So far so good...</p>
<p>But my task is to show a corresponding comment form to each loaded post. So if I have 20 posts on my single page, I have 20 comment forms beneath each post. I can't find a way of doing this.

You can use *output buffering* to achieve this effect:
```
function get_comments_form() {
ob_start();
comments_form();
$commentsform = ob_get_contents();
ob_end_clean();
return $commentsform;
}
$commentsform = get_comments_form();

<p>Is there an image bug in WP 4.4.2? I have tried the forums but no-one replies there. </p>
<p>When I upload an image, it is crunched according to my media settings. But when I go to 'Add media' and select 'Large' from the dropdown, it shows and inserts an image with width=640px, though it uses the crunched image that is 1140px wide - which incidently is my Large size. 640px I have not set anywhere. Does anyone know what is going on? I have deactivated all plugins before upload, and tried in 2015 and Underscores themes.</p>

<p>Here's the scenario - I want to select fontawesome icons from the dropdown list but it's not working. For some reason the class inside <code>span</code> is not adding up (I have tried <code>jQuery().append()</code>, CSS) but so far no luck. ANY help would be appreciated.</p>
<p><strong>Code in <code>Page.php</code> file</strong></p>
<pre><code><div class="features-block-one">
<div class="icon-one">
<span class="<?php get_theme_mod('features_one_icon' ,'fa fa-bullseye');?>"> </span>
</div>
</div>
</code></pre>
<p><strong>Code in Customizer file</strong> </p>
<pre><code>//block one icon
$wp_customize->add_setting(
'features_one_icon',
array(
'default' => 'fa-fa box',

You can use *output buffering* to achieve this effect:
```
function get_comments_form() {
ob_start();
comments_form();
$commentsform = ob_get_contents();
ob_end_clean();
return $commentsform;
}
$commentsform = get_comments_form();
```

<p>I have a php file located at:</p>
<pre><code>.../wp-content/themes/kallyas-child/pagebuilder/elements/TH_TeamBox/TH_TeamBox.php

<p>I'm trying to use the above file to overwrite the parent's <em>TH_TeamBox.php</em> file which is found here:</p>
<pre><code>.../wp-content/themes/kallyas/pagebuilder/elements/TH_TeamBox/TH_TeamBox.php

<p>My child theme is active and I have created the file path in my child theme to mimic my parent theme. I was under the impression that if I did that I would be able to edit PHP files to my liking in my child theme without losing my changes when I update my parent theme.</p>
<p>I've been developing for a while, but as you can see I'm new(er) to Wordpress. Any insight on why my child's .php file isn't overwriting it's parent's .php file would be greatly appreciated. I'd be glad to give anymore info that you might need to assist me, thanks! : ) </p>

Child themes are allowed to override *templates*, not simply arbitrary PHP files.
In WordPress, a theme consists of a bunch of PHP files which are used as Templates. You can find a list of those files in the [Template Hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/).
Those specific template files can be overridden with new ones, but unless the parent theme has some special means for you to override other files, then files simply included by the parent as part of a support structure or as libraries for a pagebuilder piece of code cannot simply be overridden in that manner.

<p>I am trying to develop a plugin to extend WooCommerce and I would like to do something with the product id when I land on a single product page (e.g. store it in the database or store it in a session variable).</p>
<p>However whatever hook I try to use, two results are given. So for example I might use the hook woocommerce_single_product_summary as follows:</p>
<pre><code>add_action( 'woocommerce_single_product_summary', 'do_my_thing' );
function do_my_thing() {
global $post;
store_the_id( $post->ID ); //some function to do something with the id

I am trying to develop a plugin to extend WooCommerce and I would like to do something with the product id when I land on a single product page (e.g. store it in the database or store it in a session variable).
However whatever hook I try to use, two results are given. So for example I might use the hook woocommerce\_single\_product\_summary as follows:
```
add_action( 'woocommerce_single_product_summary', 'do_my_thing' );
function do_my_thing() {
global $post;
store_the_id( $post->ID ); //some function to do something with the id
}
```
When a user lands on a product page, the hook is fired twice, the function store\_my\_id runs twice and with two different post ids. The first is the correct id for the product in questions, and the second is an id for some other product.
This occurs whatever hook I use e.g. get\_header. It wouldn't be a problem if I just wanted to echo something to the page because the echo only outputs when the hook fires for the first time.
Can anyone explain to me what is happening here? Is this supposed to be happening? And if so is there some way I can differentiate between the two ids returned to know which is actually the id for the product I have just landed on?
I have tried this on a completely fresh Wordpress install with just the WooCommerce plugin installed, the twentyfifteen theme and 2 products added so I don't think it's being caused by anything custom I am doing.
Any help really appreciated...
**EDIT**
I wondered whether using get\_queried\_object would help (as per below) but the same thing happens
```
add_action( 'woocommerce_single_product_summary', 'do_my_thing' );
function do_my_thing() {
$queried_object = get_queried_object();
if ( $queried_object->post_type == 'product' ) {
store_the_id( $queried_object->ID ); //some function to do something with the id
}
}
```

If your attachment is handled via the WP media library, each one has unique ID, just like Posts. When your users download the attachment by clicking the button, store a reference to that attachment ID in a `user_meta` setting and then update the button accordingly.

The PHP modulus operator gives you the remainder from dividing 2 numbers. The remainder from the division of any number by two is either 0 or 1, so we can use that to provide an "alternator". We use the `current_post` var as a counter, which is available in any `WP_Query` object:
```
while( have_posts() ){
the_post();
if( $wp_query->current_post % 2 ){
echo 'right';

What you found is actually perfectly accurate. With WP's commitment to backwards compatibility it's not that common for thing to stop working.
This filter is used in [`wp_set_auth_cookie()`](https://codex.wordpress.org/Function_Reference/wp_set_auth_cookie) to calculate the duration. Resulting value is used in PHP's [`setcookie()`](http://php.net/manual/en/function.setcookie.php).
There is no mention of specifics limits in documentation, so in practice the value is limited by integer range for Unix timestamp (practically at the moment — year 2038 give or take).
So you are pretty set on WP side, but I'd also look into how browsers handle it. I don't think I heard about extra long expiration times used in practice outside of development. So it's not well covered topic.

What you found is actually perfectly accurate. With WP's commitment to backwards compatibility it's not that common for thing to stop working.
This filter is used in [`wp_set_auth_cookie()`](https://codex.wordpress.org/Function_Reference/wp_set_auth_cookie) to calculate the duration. Resulting value is used in PHP's [`setcookie()`](http://php.net/manual/en/function.setcookie.php).
There is no mention of specifics limits in documentation, so in practice the value is limited by integer range for Unix timestamp (practically at the moment — year 2038 give or take).
So you are pretty set on WP side, but I'd also look into how browsers handle it. I don't think I heard about extra long expiration times used in practice outside of development. So it's not well covered topic.

<p>I have a WP site with multiple post types. Posts, products w/taxonomies.</p>
<p>I have my WP Default posts_per_page setting at 10 in the admin. I want to keep this setting as the blog would be best at 10 per page.</p>
<p>However on a page/template like taxonomyNAme-archive.php I want to get many more than 10. But I don't need a custom query, since WP knows what posts to get me. Can I hijack the posts_per_page without writing a custom query?</p>

Use the [`pre_get_posts`](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) action to modify query parameters before the queries are run. You can use many of the [Conditional Tags](https://codex.wordpress.org/Conditional_Tags) to target specific types of pages.
```
function wpd_alter_posts_per_page( $query ) {
// don't alter admin or custom queries
if ( is_admin() || ! $query->is_main_query() )
return;
// if this is your-custom-tax archive
if ( is_tax( 'your-custom-tax' ) ) {
$query->set( 'posts_per_page', 20 );
return;
}
}
add_action( 'pre_get_posts', 'wpd_alter_posts_per_page' );
```

<p>It seems that some of the css on the table that shows the list of all the pages adversely reacts with one of my plugins, which adds a bunch of columns to the table. I'm pretty sure this is edit.php. At least, that's what's in the URL.</p>
<p>Using the developer tools in Chrome I noticed that the table contains a class called <code>fixed</code>, which adds <code>table-layout:fixed</code> to the table styles. Removing it clears up the problem.</p>
<p>The question is, how do I edit the styles for this table?</p>
<p>Here's the relevant code:</p>
<pre><code><form id="posts-filter" method="get">
...
<h2 class='screen-reader-text'>Pages list</h2>
<table class="wp-list-table widefat fixed striped pages">
</code></pre>
<p>The form element is the closet parent with an ID. The table with class <code>wp-list-table</code> is what needs to be targeted. Removing the <code>fixed</code> class fixes the problem, at least in the developer tools. How do I remove it?</p>

A bit of a hack fix, I installed Tampermonkey for Chrome (a userscript manager) and created the following userscript:
```
// ==UserScript==
// @name Fix edit.php!
// @author You
// @match http://www.example.com/wp-admin/edit.php*
// @grant none
// ==/UserScript==
(function() {
'use strict';
// Your code here...
function addGlobalStyle(css) {
var head, style;
head = document.getElementsByTagName('head')[0];
if (!head) { return; }
style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = css;
head.appendChild(style);
}
addGlobalStyle('.fixed { table-layout:auto !important; }');
})();
```
It's light, so it doesn't slow down the page at all. As far as I can tell, the problem doesn't exist anymore since a WP update, but I still have the userscript just in case.

The situation is this: I have created a custom post type which works perfectly, now I want to create a specific archive page template for the taxonomies of this post type.
I duplicated the `archive.php` page of my theme (schema by MTS) but it doesn't work in this case.
Here the code:
```
<?php
$term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ), get_query_var( 'count' ) );
echo $term->name;
echo ' has nr elements: ';
echo $term->count;
?>
<div id="page">
<div class="<?php mts_article_class(); ?>">
<div id="content_box">
<h1 class="postsby">
<span><?php echo the_archive_title(); ?></span>
</h1>
<?php $j = 0; if (have_posts()) : while (have_posts()) : the_post(); ?>
<article class="latestPost excerpt <?php echo (++$j % 3 == 0) ? 'last' : ''; ?>">
<?php mts_archive_post(); ?>
</article><!--.post excerpt-->
<?php endwhile; else: echo 'nothing'; endif; ?>
<?php if ( $j !== 0 ) { // No pagination if there is no posts ?>
<?php mts_pagination(); ?>
<?php } ?>
</div>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
```
The strange aspect is that the code print "nothing" because the function `have_posts()` return false but the `$term->count` is `3`.
Can you help me please? Thank you very much in advance!

I had same problem.
According to [documentation](https://developer.wordpress.org/themes/template-files-section/taxonomy-templates/):
```
The hierarchy for a custom taxonomy is listed below:
taxonomy-{taxonomy}-{term}.php
taxonomy-{taxonomy}.php
taxonomy.php
archive.php
index.php
```
So, it doesn't matter witch template file you are using, all of them will generate same issue.
When I put in the beginning of template file code `var_dump($wp_query);`, i found this:
```
public 'request' => string 'SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) WHERE 1=1 AND (
wp_term_relationships.term_taxonomy_id IN (20)
) AND wp_posts.post_type IN ('post', 'page', 'attachment') AND (wp_posts.post_status = 'publish' OR wp_posts.post_author = 1 AND wp_posts.post_status = 'private') GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10' (length=433)
public 'posts' =>
```
Important part in this query is `wp_posts.post_type IN ('post', 'page', 'attachment')`.
Problem occur because there is no your custom `post_type` in this array `('post', 'page', 'attachment')`.
I don't know why it's happen, but it's possible to fix it using `pre_get_posts` hook:
```
add_filter('pre_get_posts', 'add_custom_post_type_to_query');
function add_custom_post_type_to_query($query) {
// We do not want unintended consequences.
if ( is_admin() || ! $query->is_main_query() ) {
return;
}
// Check if custom taxonomy is being viewed
if( is_tax() && empty( $query->query_vars['suppress_filters'] ) )
{
$query->set( 'post_type', array(
'post',
'page',
'my_custom_post_type'
) );
}
}
```
