```
function theme_styles_and_scripts() {
wp_enqueue_style('bootstrap', get_template_directory_uri() . '/css/bootstrap.min.css', array(), '3.3.6', 'all' );
}
add_action( 'wp_enqueue_scripts', 'theme_styles_and_scripts' );
``` | There can be multiple reasons why it may not be working.
**Possibility-1:** You are adding the CSS file in a child theme. In that case, use the following CODE instead:
```
function theme_styles_and_scripts() {
wp_enqueue_style( 'bootstrap', get_stylesheet_directory_uri() . '/css/bootstrap.min.css', array(), '3.3.6', 'all' );
}
add_action( 'wp_enqueue_scripts', 'theme_styles_and_scripts' );
```
[`get_stylesheet_directory_uri()`](https://developer.wordpress.org/reference/functions/get_stylesheet_directory_uri/) returns the URL of your current theme (whether it is a child theme or not). On the other hand, [`get_template_directory_uri()`](https://developer.wordpress.org/reference/functions/get_template_directory_uri/) returns the parent theme URL if you are using a child theme & the current theme URL only if the active theme is not a child theme of another theme.
**Possibility-2:** You are not calling `wp_head()` anywhere in your theme's template files (usually `header.php`). However, if you are modifying any standard theme, then this is not the likely case, as any standard theme will not make this mistake.
**Other Possibilities:**
However, if you view HTML source & see that you are finding `bootstrap` in it, then perhaps another call to `wp_enqueue_style` with the same name is overriding it ([as suggested by this answer](https://wordpress.stackexchange.com/a/256674/110572)) or perhaps your CSS is being added, but some other CSS is overriding your CSS rules.
**How to Debug:**
An easy way to debug this issue is to create a simple CSS file with the following CSS CODE:
```
body {
background-color: red !important;
}
```
Then save the CSS file in your theme's `css` folder with the name `wpse256672-style.css`.
Then use the following CODE in your theme's `functions.php` file:
```
function wpse256672_css_enqueue() {
wp_enqueue_style( 'wpse256672_css', get_stylesheet_directory_uri() . '/css/wpse256672-style.css', array(), '1.0.0', 'all' );
}
add_action( 'wp_enqueue_scripts', 'wpse256672_css_enqueue' );
```
Now if you reload the page after saving the above, you should see red background in your page. That means you don't have `Possibility-2` above, but perhaps `Possibility-1` or something else. Change CSS file name, `$handle` from `bootstrap` to something else, change version number, check if the file exists etc.

**Possibility-1:** You are adding the CSS file in a child theme. In that case, use the following CODE instead:
```

wp_enqueue_style( 'bootstrap', get_stylesheet_directory_uri() . '/css/bootstrap.min.css', array(), '3.3.6', 'all' );

add_action( 'wp_enqueue_scripts', 'theme_styles_and_scripts' );
```
[`get_stylesheet_directory_uri()`](https://developer.wordpress.org/reference/functions/get_stylesheet_directory_uri/) returns the URL of your current theme (whether it is a child theme or not). On the other hand, [`get_template_directory_uri()`](https://developer.wordpress.org/reference/functions/get_template_directory_uri/) returns the parent theme URL if you are using a child theme & the current theme URL only if the active theme is not a child theme of another theme.
**Possibility-2:** You are not calling `wp_head()` anywhere in your theme's template files (usually `header.php`). However, if you are modifying any standard theme, then this is not the likely case, as any standard theme will not make this mistake.
**Other Possibilities:**

Then save the CSS file in your theme's `css` folder with the name `wpse256672-style.css`.

}

wp_enqueue_style( 'bootstrap', get_stylesheet_directory_uri() . '/css/bootstrap.min.css', array(), '3.3.6', 'all' );
}
add_action( 'wp_enqueue_scripts', 'theme_styles_and_scripts' );
```
[`get_stylesheet_directory_uri()`](https://developer.wordpress.org/reference/functions/get_stylesheet_directory_uri/) returns the URL of your current theme (whether it is a child theme or not). On the other hand, [`get_template_directory_uri()`](https://developer.wordpress.org/reference/functions/get_template_directory_uri/) returns the parent theme URL if you are using a child theme & the current theme URL only if the active theme is not a child theme of another theme.
**Possibility-2:** You are not calling `wp_head()` anywhere in your theme's template files (usually `header.php`). However, if you are modifying any standard theme, then this is not the likely case, as any standard theme will not make this mistake.
**Other Possibilities:**
However, if you view HTML source & see that you are finding `bootstrap` in it, then perhaps another call to `wp_enqueue_style` with the same name is overriding it ([as suggested by this answer](https://wordpress.stackexchange.com/a/256674/110572)) or perhaps your CSS is being added, but some other CSS is overriding your CSS rules.
**How to Debug:**
An easy way to debug this issue is to create a simple CSS file with the following CSS CODE:
```
body {
background-color: red !important;
}
```
Then save the CSS file in your theme's `css` folder with the name `wpse256672-style.css`.
Then use the following CODE in your theme's `functions.php` file:
```
function wpse256672_css_enqueue() {
wp_enqueue_style( 'wpse256672_css', get_stylesheet_directory_uri() . '/css/wpse256672-style.css', array(), '1.0.0', 'all' );
}
add_action( 'wp_enqueue_scripts', 'wpse256672_css_enqueue' );
```
Now if you reload the page after saving the above, you should see red background in your page. That means you don't have `Possibility-2` above, but perhaps `Possibility-1` or something else. Change CSS file name, `$handle` from `bootstrap` to something else, change version number, check if the file exists etc.

| I'm displaying a gallery image but I also want display the caption for image. I can get the info that we insert when us upload a image in WordPress Dashboard like "Title/Caption/ALT/Description". I want get anyone and display.
```

</div>
</div>
```
Reading at the docs of [get\_post\_gallery\_images](https://codex.wordpress.org/Function_Reference/get_post_gallery_images) I didn't find a solution for my issue.
I also found [this answer](https://wordpress.stackexchange.com/questions/125554/get-image-description) but I don't know if it works and I've erros to implement in my code.
Anyway, how can I solve this? | You need to get the `metadata` of each image, add this to your `functions.php` file:
```
function get_post_gallery_images_with_info($postvar = NULL) {
if(!isset($postvar)){
global $post;
$postvar = $post;//if the param wasnt sent
}
$post_content = $postvar->post_content;
preg_match('/\[gallery.*ids=.(.*).\]/', $post_content, $ids);
$images_id = explode(",", $ids[1]); //we get the list of IDs of the gallery as an Array
$image_gallery_with_info = array();
//we get the info for each ID
foreach ($images_id as $image_id) {
$attachment = get_post($image_id);
array_push($image_gallery_with_info, array(
'alt' => get_post_meta($attachment->ID, '_wp_attachment_image_alt', true),
'caption' => $attachment->post_excerpt,
'description' => $attachment->post_content,
'href' => get_permalink($attachment->ID),
'src' => $attachment->guid,
'title' => $attachment->post_title
)
);
}
return $image_gallery_with_info;
}
```
use it in your logic like this:
```
<?php
$gallery = get_post_gallery_images_with_info($post); //you can use it without params too
foreach( $gallery as $image_obj ) :
?>
<div class="item" style="background-image: url('<?php echo $image_obj['src'] ?>'); background-size: cover">
<div class="caption">
<!-- Here I want display the Title/Caption/ALT/Description of image -->
<h2><?php echo $image_obj['title']." ". $image_obj['caption']." ".$image_obj['description']; ?> </h2>
</div>
</div>
<?php
endforeach;
?>
```
it will output like this:
[](https://i.stack.imgur.com/2sZ2N.png)
each image returned by the function is an array like this:
```
Array
(
[alt] => Alt Coffe
[caption] => Caption coffe
[description] => Description coffe
[href] => http://yoursite/2017/02/14/hello-world/coffee/
[src] => http://yoursite/wp-content/uploads/sites/4/2017/02/coffee.jpg
[title] => coffee
)
```
notice `href` and `src` are different, one is the permalink and the other the direct `URL`. |

To change the logo URL of your homepage, you will have to look into your theme's `header.php` file. You logo and it's link are included there. Depending on your theme, they way that your URL is generated may be different.

256,724 | <p>I'm using a child theme based on 'Twenty Seventeen' and have created a custom post type ('review').</p>
<p>I want to make two Pages, one which lists 'reviews' and the other which lists a mixture of 'posts' and 'reviews' (ordered by recency).</p>
<p>For the first of those I've made a copy of Twenty Seventeen's <code>index.php</code>, as <code>page-reviews.php</code>, and added code like this at the start:</p>
<pre><code>$args = array(
'post_type' => 'review',
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => 10,
);
$the_query = new WP_Query( $args );
</code></pre>
<p>Then, further down, replaced <code>have_posts()</code> and <code>the_post()</code> with <code>$the_query->have_posts()</code> and <code>$the_query->the_post()</code> respectively.</p>
<p>If I choose to use that template for a Page then it works in that the 'reviews' are listed, <em>but</em> the layout is all messed up. There are a lot of classes in the <code><body></code> which mess up the layout.</p>
<p>For example, the standard blog front page, using <code>index.php</code>, has these classes in its <code><body></code> and looks fine:</p>
<pre><code>blog logged-in admin-bar hfeed has-header-image has-sidebar colors-light customize-support
</code></pre>
<p>While my custom page has these:</p>
<pre><code>page-template page-template-page-postslist page-template-page-postslist-php page page-id-15071 logged-in admin-bar has-header-image page-two-column colors-light customize-support
</code></pre>
<p>How can I make a custom template that acts more like <code>index.php</code> in terms of the classes it adds?</p>

| I'm using a child theme based on 'Twenty Seventeen' and have created a custom post type ('review').
I want to make two Pages, one which lists 'reviews' and the other which lists a mixture of 'posts' and 'reviews' (ordered by recency).
For the first of those I've made a copy of Twenty Seventeen's `index.php`, as `page-reviews.php`, and added code like this at the start:
```
$args = array(
'post_type' => 'review',
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => 10,
);
$the_query = new WP_Query( $args );
```
Then, further down, replaced `have_posts()` and `the_post()` with `$the_query->have_posts()` and `$the_query->the_post()` respectively.
If I choose to use that template for a Page then it works in that the 'reviews' are listed, *but* the layout is all messed up. There are a lot of classes in the `<body>` which mess up the layout.
For example, the standard blog front page, using `index.php`, has these classes in its `<body>` and looks fine:
```
blog logged-in admin-bar hfeed has-header-image has-sidebar colors-light customize-support
```
While my custom page has these:
```
page-template page-template-page-postslist page-template-page-postslist-php page page-id-15071 logged-in admin-bar has-header-image page-two-column colors-light customize-support
```
How can I make a custom template that acts more like `index.php` in terms of the classes it adds? | The `login_headerurl` filter is for changing the logo url of login page, according to the [Codex](https://codex.wordpress.org/Plugin_API/Filter_Reference/login_headerurl).
To change the logo URL of your homepage, you will have to look into your theme's `header.php` file. You logo and it's link are included there. Depending on your theme, they way that your URL is generated may be different.
Access your `header.php` file from `Appearance > Edit` in the admin panel, and search for the line containing the logo. There, you can change it to whatever you want. |

| I have a custom post type `event` in WordPress, and I need to query upcoming `event` `posts` comparing `$current_date`.
Query conditions are :
* `start_date` is a valid `date` always
* `end_date` can be a valid `date` or `null` or `empty` string.
* IF `end_date` is a valid `date` in db record then compare `end_date >= $current_date`
* ELSE IF `end_date` is `null` or `empty` then compare `start_date >=$current_date`.
Now If `end_date` was not optional , I could use below code to get desired results.
```
$args= array();
$args['post_type'] = "event";
$args['meta_query'] = array(
array(
'key' => 'end_date',
'compare' => '>=',
'value' => date("Ymd",$current_date),
)
);
$post_query = new WP_Query();
$posts_list = $post_query->query($args);
```
My problem is, how do I handle optional `end_date` in above code.

256,754 | <p>I am trying to edit theme editor to edit files on wordpress, but I get the error about, the file is not writable. So now I want to give the account write permissions on the file, but I don't know which user account wordpress runs as on the website when editing files. Does anyone know?</p>

Here is the trick. The WHERE Statement has both <code>meta_key</code>, <code>meta_value</code>.</p>\n\n<p>We know <code>meta_value</code> is always the same, which is the current date.</p>\n\n<p>So for <code>meta_key</code> we run an IF statement that checks how many post meta rows the current post ID has where its meta key is equal to 'end_date'.</p>\n\n<p>If it has more than 0 rows, then set <code>meta_key</code> to 'end_date' (second argument in the IF function), otherwise set it to 'start_date' (third argument).</p>\n\n<p>We also check post type and make sure they are published and limit the return to 10 (or whatever you'd like).</p>\n\n<p>Finally, we fetch the results to use them as we please.</p>\n\n<p>I know its a bit of a hack, but it works. Its also a bit slow, so might be worth caching the results</p>\n\n<p>Hope that's what you are looking for! And if you find a better solution, please let me know :)</p>\n"

Thanks | There is no need to craft a custom SQL query in order to achieve this. Since version 4.1, WordPress's query classes have [supported complex/nested meta queries](https://core.trac.wordpress.org/ticket/29642). So you can craft a query like this:
```
$args['meta_query'] = array(
// Use an OR relationship between the query in this array and the one in
// the next array. (AND is the default.)
'relation' => 'OR',
// If an end_date exists, check that it is upcoming.
array(
'key' => 'end_date',
'compare' => '>=',
'value' => date( 'Ymd', $current_date ),
),
// OR!
array(
// A nested set of conditions for when the above condition is false.
array(
// We use another, nested set of conditions, for if the end_date
// value is empty, OR if it is null/not set at all.
'relation' => 'OR',
array(
'key' => 'end_date',
'compare' => '=',
'value' => '',
),
array(
'key' => 'end_date',
'compare' => 'NOT EXISTS',
),
),
// AND, if the start date is upcoming.
array(
'key' => 'start_date',
'compare' => '>=',
'value' => date( 'Ymd', $current_date ),
),
),
);

Would really appriciate any help! | In a quick view, the arguments you use in [`wp_enqueue_style()`](https://developer.wordpress.org/reference/functions/wp_enqueue_style/) are not correct for global.css. The third parameter is used to declare the dependencies and you have set that parameter to the string `'false'` but it should be an array. If the CSS does not depend on another CSS, use an empty array.
In your case, I guess that the global.css depends on the other css you are lodaing (foundation, normalize, etc), so you should declare those dependencies.
You are using the fourth parameter incorrectly too. The fourth parameter is used to specified the version. `'all'` seems not a version. If you don't want to declare a version, use `null`, but I think it is good to declare the version in all the CSS files you are loading. For example, if you use some browser cache and update the foundation CSS, the upade won't be sent to the users that have the CSS already cached in their browsers. If you declare the version, the URL will change after the update and the users will get the new CSS version.
There is also a missing `/` in the URL (noted by Pedro in his answer).
```
wp_enqueue_style( 'venix_css', get_template_directory_uri() . '/css/global.css', array( 'normalize_css', 'foundation_css', 'googlefont_css' ), '1.0' );
```
Also, since WordPress 4.7, it is better if you use [`get_theme_file_uri()`](https://developer.wordpress.org/reference/functions/get_theme_file_uri/) instead of `get_template_directory_uri()`. The new function is more flexible and allows child themes to override parent theme files easily.
```
wp_enqueue_style( 'venix_css', get_theme_file_uri( 'css/global.css' ) , array( 'normalize_css', 'foundation_css', 'googlefont_css' ), '1.0' );

| What is the benefit of using (advantage/disadvantage)
```
Organize my uploads into month- and year-based folders
```
option? Why would I want to organize my folder structure like this ? Is there SEO advantages ?
Thank you | This is one of the many optional features in WordPress.There is no real benefit in using any of these 2 structures, but here is some details for you:
**Organization:**
When you are building a website which will have a lot of uploads, it is always a good option to go for the year / month structure. You might end up with 100,000 uploads in a single folder if you don't.
As you can imagine, sorting, reading and listing these files will get a long time. There was a time when old file systems used to support limited files in a single folder ( They still do now, but it's way more than before), so you had to make more folders to be able to save the images.
A website with 50K images and 5 thumbnail sizes will end up having 300k images in a single folder!
**SEO benefits**
There is no actual benefit of having a year / month structure on your files when it comes to SEO. Search engines have other tools to understand your contents, such as [Structured data](http://schema.org/) or HTML5 structure, which let's the search engine understand different parts of a page without using a MicroData structure.
**Custom templates - Security**
Some users (such as me) prefer to have their website deeply customized, including default folder names. I myself have changed the name all `wp-content`, `wp-admin`, `uploads` and `wp-includes` folder. Some directly, some through rewriting.
So the first moment a visitor visits the website, it's not easy to understand whether this website is powered by WordPress or not. It also makes it a bit more difficult for a newbie hacker to determine the CMS of the website.
However, with the year / month structure turned to ON, it needs one second to realize that this website is using WordPress to power up.
Although there are several ways to go around this, but still, some do prefer it.
There can be many other things added to this list, their all optional, such as the above list.
I hope this helps you decide what to choose about this. |

``` | Why it is added in the footer:
==============================
This is the expected behaviour.
Since you have enqueued the style ***within your Shortcode hook function***, by the time it executes, WordPress is already done generating the `<head>` section of your page, since WordPress will only execute your shortcode function once it has found the shortcode in your content.
So it has no other way than to place your style in the footer section if you enqueue style within the shortcode hook function.
How to add it in the header:
============================
If you want to output it in `<head>` section, you must enqueue it using:
```
function enqueue_your_styles() {
// the following line is just a sample, use the wp_enqueue_style line you've been using in the shortcode function
wp_enqueue_style( 'style-name', get_stylesheet_directory_uri() . '/css/your-style.css' );
}
add_action( 'wp_enqueue_scripts', 'enqueue_your_styles' );
```

| I'm trying to eliminate "mixed content" on my website and have done so with every area of the site except for one.
Any image uploaded via the Theme Customizer is not protocol relative nor https, all images uploaded via the customizer come up "http://".
The Customizer uses the Media Gallery uploader but doesn't seem to act in the same manner. If I upload an image to the media gallery (no customizer), place it into a page, WP knows whether or not to switch between http and https, although, when the same is attempted via the theme customizer function:
```
$wp_customize->add_setting('slide_img_upload_one');
$wp_customize->add_control(new WP_Customize_Image_Control($wp_customize, 'slide_img_upload_one', array(
'label' => __('Upload first image:', 'example_theme'),
'section' => 'carousel_slide_section',
'settings' => 'slide_img_upload_one',
'description' => 'Upload your first slider image here.'
)));
```
I can not get the `WP_Customize_Image_Control();` to output either "https" or a (best case scenario) protocol relative `//` url to the image for SSL compliance.
Some things to note. I'm not going to force SSL on my website so in Settings -> General; I'm not changing the url away from the http protocol.
I am also not looking for a way to use .htaccess to force this action.

| I'm attempting to add my logo to the middle of my navbar, and while looking at the nav walker class I couldn't figure what the best way to do this would be.
So my question is essentially how do I do that. the Walker\_Nav\_Menu() method start\_el() seems to build only one li so where is it iterating over all of them and writing them to file. | You need to make your own walker menu (i am guessing you already know that), and the best way i think is overriding the function that `ends` each menu item which is `end_el` :
```
class logo_in_middle_Menu_Walker extends Walker_Nav_Menu {
public $menu_location = 'primary';
function __construct($menu_location_var) {
// parent class doesnt have a constructor so no parent::__construct();
$this->menu_location = $menu_location_var;
}
public function end_el(&$output, $item, $depth = 0, $args = array()) {
$locations = get_nav_menu_locations(); //get all menu locations
$menu = wp_get_nav_menu_object($locations[$this->menu_location]); //one menu for one location so lets get the menu of this location
$menu_items = wp_get_nav_menu_items($menu->term_id);
$top_lvl_menu_items_count = 0; //we need this to work with a menu with children too so we dont use simply $menu->count here
foreach ($menu_items as $menu_item) {
if ($menu_item->menu_item_parent == "0") {
$top_lvl_menu_items_count++;
}
}
$total_menu_items = $top_lvl_menu_items_count;
$item_position = $item->menu_order;
$position_to_have_the_logo = ceil($total_menu_items / 2);
if ($item_position == $position_to_have_the_logo && $item->menu_item_parent == "0") { //make sure we output for top level only
$output .= "</li>\n<img src='PATH_TO_YOUR_LOGO' alt='' />"; //here we add the logo
} else {
$output .= "</li>\n";
}
}
}
```
i am assuming that if its a menu with an uneven number of item say 5 the logo will be after the third element, also that this is only for top elements only.
you have to use it like this in the menu location:
```
<?php
wp_nav_menu(array(
'theme_location' => 'footer',
"walker" => new logo_in_middle_Menu_Walker('footer'),
));
?>
```
you have to supply the name of the theme location.

256,897 | <p>Wondering if you might have some ideas on this problem. I’m googled for days but can’t figure it out. </p>
<p>Here’s where I’m at:</p>
<p>I have a meta box for the Woocommerce post type ‘products’. Inside the meta box there’s a <code>'type' = > 'select'</code> that I want to populate with a list of all of the available <code>'taxonomy' = > 'product_cat'</code>.</p>
<p>I can get the select box to populate and work with the standard post categories, <code>'taxonomy' = > 'category'</code> using the following code:</p>
<pre><code>function product_cats() {
$options = array();
$categories = get_terms( array( 'taxonomy' => 'category' ) );
foreach( $categories as $category ) {
$options[$category->term_id] = array(
'label' => $category->name,
'value' => $category->slug
);
}
// return array('options'=>$options);
return $options;
}
</code></pre>
<p>It all falls apart though when I try to use <code>‘taxonomy' = > ‘product_cat’</code> or any other custom taxonomy I have. </p>
<p>I thought the issue was that I’m trying to access the custom taxonomy before it’s being registered, so I swapped around some declarations/calls in my function.php file (ones which call the CPT, meta boxes, and woocommece) to potentially change the order that things run in but no luck.</p>
<p>BUT, based on the question and answer below, I can now confirm that the function can 'see' and display all terms, across taxonomies. If I exclude the <code>'taxonomy =></code> from the arguments it returns terms from across custom post types and taxonomies. </p>
<p>Ideally the basic function would read:</p>
<pre><code>function product_cats() {
$options = array();
$categories = get_terms( array( 'taxonomy' => 'product_cat' ) );
foreach( $categories as $category ) {
$options[$category->term_id] = array(
'label' => $category->name,
'value' => $category->slug
);
}
// return array('options'=>$options);
return $options;
}
</code></pre>
<p>Just wondering if you had any general thoughts? I know it’s difficult without seeing the whole code base, but I thought it would be worth an ask. </p>
<p>Wordpress Version 4.7.2</p>
<p>Woocommerce Version 2.6.14</p>
<p><strong>UPDATE:</strong></p>
<p>Slowly I'm trying to pinpoint my issue.</p>
<p>It appears that <code>'product_cat'</code> can be accessed after all (good) but it's spitting out an array that's not displaying properly. </p>
<p>This is confusing to me as if I simply use <code>get_terms()</code> without any parameters, or specifying <code>'taxonomy' => 'category'</code> the code above works flawlessly</p>
<p>The other pieces of code that I need to work with this are: </p>
<p><em>The array that I'd like the list of options to dump in to</em></p>
<pre><code> array(
'label'=> 'Collections',
'desc' => 'Select the collection you would like to display',
'id' => $prefix.'collection',
'type' => 'select',
'options' => product_cats()
),
</code></pre>
<p><em>the code which generates the select list (used for other meta fields)</em></p>
<pre><code>// select
case 'select':
echo '<select name="'.$field['id'].'" id="'.$field['id'].'">';
foreach ($field['options'] as $option) {

| Wondering if you might have some ideas on this problem. I’m googled for days but can’t figure it out.
Here’s where I’m at:
I have a meta box for the Woocommerce post type ‘products’. Inside the meta box there’s a `'type' = > 'select'` that I want to populate with a list of all of the available `'taxonomy' = > 'product_cat'`.
I can get the select box to populate and work with the standard post categories, `'taxonomy' = > 'category'` using the following code:
```
function product_cats() {
$options = array();
$categories = get_terms( array( 'taxonomy' => 'category' ) );
foreach( $categories as $category ) {
$options[$category->term_id] = array(
'label' => $category->name,
'value' => $category->slug
);
}
// return array('options'=>$options);
return $options;
}
```
It all falls apart though when I try to use `‘taxonomy' = > ‘product_cat’` or any other custom taxonomy I have.
I thought the issue was that I’m trying to access the custom taxonomy before it’s being registered, so I swapped around some declarations/calls in my function.php file (ones which call the CPT, meta boxes, and woocommece) to potentially change the order that things run in but no luck.
BUT, based on the question and answer below, I can now confirm that the function can 'see' and display all terms, across taxonomies. If I exclude the `'taxonomy =>` from the arguments it returns terms from across custom post types and taxonomies.
Ideally the basic function would read:
```
function product_cats() {
$options = array();
$categories = get_terms( array( 'taxonomy' => 'product_cat' ) );
foreach( $categories as $category ) {
$options[$category->term_id] = array(
'label' => $category->name,
'value' => $category->slug
);
}
// return array('options'=>$options);
return $options;
}
```
Just wondering if you had any general thoughts? I know it’s difficult without seeing the whole code base, but I thought it would be worth an ask.
Wordpress Version 4.7.2
Woocommerce Version 2.6.14
**UPDATE:**
Slowly I'm trying to pinpoint my issue.
It appears that `'product_cat'` can be accessed after all (good) but it's spitting out an array that's not displaying properly.
This is confusing to me as if I simply use `get_terms()` without any parameters, or specifying `'taxonomy' => 'category'` the code above works flawlessly
The other pieces of code that I need to work with this are:
*The array that I'd like the list of options to dump in to*
```
array(
'label'=> 'Collections',
'desc' => 'Select the collection you would like to display',
'id' => $prefix.'collection',
'type' => 'select',
'options' => product_cats()
),
```
*the code which generates the select list (used for other meta fields)*
```
// select
case 'select':
echo '<select name="'.$field['id'].'" id="'.$field['id'].'">';
foreach ($field['options'] as $option) {
echo '<option', $meta == $option['value'] ? ' selected="selected"' : '', ' value="'.$option['value'].'">'.$option['label'].'</option>';
}
echo '</select><br /><span class="description">'.$field['desc'].'</span>';
break;
```
I have zero issues with any other meta fields working or displaying, including select lists.
I'd rather no re-write the entire meta box with all of its fields so I'm trying to work with what I have at the moment. | For the life of me I really want to get this working the *right way*. For the life of me I can't figure the integration out.
Previously I had looked at [`wp_dropdown_categories()`](https://codex.wordpress.org/Function_Reference/wp_dropdown_categories) and thought it was a better (and easier) solution. I landed working on the problem above because I couldn't figure out how to get it to working with the existing meta box syntax.
For now I've decided on the temporary fix found below. It's not ideal and certainly not the best way, but it allows me to move forward with calling the values in the templates that will utilize this field.
```
// Wrap all categories in a function
function product_cats() {
$output = array();
$categories = get_terms( array(
'orderby' => 'name',
'pad_counts' => false,
'hierarchical' => 1,
'hide_empty' => true,
) );
foreach( $categories as $category ) {
if ($category->taxonomy == 'product_cat' ) {
$output[$category->slug] = array(
'label' => $category->name,
'value' => $category->slug
);
}
}
//return array('options'=>$output);
return $output;
}
```

256,904 | <p>I migrated my wordpress, and the subscribe2 plugin
<a href="https://wordpress.org/plugins/subscribe2/installation/" rel="nofollow noreferrer">https://wordpress.org/plugins/subscribe2/installation/</a></p>
<p>looks different now. Before it has a text box with a placeholder, and then two buttons under saying subscribe and unsubscribe. The old plugin was version 4.16, and now the new version is 10.21. The way the new version looks like, is there is no input field or buttons. Rather it's just a sentence that says "you may manage your subscription options from your profile". And "profile" is a link.</p>
<p>Does anyone know how to get it to look like the old way?</p>

| I created a page template named custpage.php
I also created a separate css file named style2.css to style the custpage which has html and php code.
The page templates loads fine it shows under the page attributes but the css stylesheet doesn't seem to work.
This is what I did in functions.php
```
function register_cust_style() {
if ( is_page_template( 'custpage.php' ) ) {
wp_enqueue_style( 'vega', get_stylesheet_directory_uri() . '/style2.css' );
}
}
add_action( 'wp_enqueue_scripts', 'register_cust_style' );
```
The css file is inside vega/style2.css (where vega is name of the template directory). | This will work only if your template is in the root folder, if its in a subdirectory you need to supply that too:
```
if ( is_page_template( 'template_folder_name/custpage.php' ) ) {
wp_enqueue_style( 'vega', get_stylesheet_directory_uri() . '/style2.css' );
}

256,967 | <p>My website has a logo and this logo have 2 states (i.e. online and offline ). Each of them has an image that will be uploaded to the media. What I am trying to achieve is that, when hovering on, the state of the logo changes (this can be done quite easy). However, in order to easily keep track of the logo image, I am thinking of allowing the theme to support custom_logo through add_theme_support. This works halfway, meaning I can only control 1 of the image at the moment. Are there any ways I can allow adding 2 different images from the theme customizing (custom logo) and display them?

Thanks in advance | I am assuming that by online and offline you mean active states of the logo. I think there are several options for you to use. The first two options can be used within your theme and then are simply changing the image file within the directory.
### Option One (not using WP):
You can utilise a simple use of transparancy. Apply a transparent effect to the logo and then on hover, make the opacity full. E.g:
```
.logo {
opacity: 0.75;
}
.logo:hover {
opacity: 1;
}
// If you want to use SASS:
.logo {
opacity: 0.75;
&:hover {
opacity: 1;
}
}
```
### Option Two (not using WP):
If you need to use imagery instead of an hover effect, then you can try the following (again using classes):
```
.logo {
background-image: url('path/to/your-off-image.jpg');
background-repeat: no-repeat;
background-size: cover;
width: 200px; // Have to set a width/height in order for the background to appear
height: 200px;
}
.logo:hover {
background-image: url('path/to/your-on-image.jpg');
background-repeat: no-repeat;
background-size: cover;
}
// If you want to use SASS:
.logo {
background-image: url('path/to/your-off-image.jpg');
background-repeat: no-repeat;
background-size: cover;
width: 200px; // Have to set a width/height in order for the background to appear
height: 200px;
&:hover {
background-image: url('path/to/your-on-image.jpg');
background-repeat: no-repeat;
background-size: cover;
}
}
```
### Option Three (using the customiser in WP):
*Taken from the [WP Customiser Docs](https://codex.wordpress.org/Theme_Customization_API#Adding_a_New_Setting)*
With this option you have to register the setting using the following:
```
function mytheme_customize_register( $wp_customize ) {
//All our sections, settings, and controls will be added here
$wp_customize->add_section( 'my_site_logo' , array(
'title' => __( 'My Site Logo', 'mytheme' ),
'priority' => 30,
) );
$wp_customize->add_control(
new WP_Customize_Image_Control(
$wp_customize,
'logo',
array(
'label' => __( 'Upload a logo', 'theme_name' ),
'section' => 'my_site_logo',
'settings' => 'my_site_logo_id'
)
)
);
}
add_action( 'customize_register', 'mytheme_customize_register' );
```
The above code would be added into the functions.php file that should be located within your theme directory. In order retrieve the image you do the following:
```
get_theme_mod( 'my_site_logo_id' );
```
And then you would have to break with convention of using inline-styling to output the two different options for the logos, on hover.
Please check out the codex to check over the various options you may have in order to achieve what you are after. |

Thanks,
Jacob | You can access the menu metadata using the `wp_get_nav_menu_object` function
BY NAME:
```
$menu = wp_get_nav_menu_object("my mainmenu" );
```
BY SLUG:
```
$menu = wp_get_nav_menu_object("my-mainmenu" );
```
The return object as follows:
```
Object (
term_id => 4
name => My Menu Name
slug => my-menu-name
term_group => 0
term_taxonomy_id => 4
taxonomy => nav_menu
description =>
parent => 0
count => 6
)

To display the name:
```
echo $menu->name;

| The following code gives all posts from the network.
What I am trying to achieve :
* Select which blogs to display (by ID)
* Select how many post to display (My code selects how many post **per blog**)
* Order by date or random
```
$blogs = get_last_updated();
foreach ($blogs AS $blog) {
switch_to_blog($blog["blog_id"]);
$lastposts = get_posts('numberposts=3');
foreach($lastposts as $post) : ?>

<?php endforeach;

``` | I created a plugin which does something similar (called Multisite Post Display <https://wordpress.org/plugins/multisite-post-reader/> ) . It displays posts from all multisite sub-sites.
The code in there might be helpful for what you are doing. You are welcome to dig into it and use the code to help with your project. (After all, I used other people's code snippets to develop it.)
I wrote it after I did the Multisite Media Display, since I wanted a way to display media from subsites on one page, and couldn't find any plugin that did that. Both have been useful to monitor posted media and content from my multisite.
Free, open source, and all that. Hope it is helpful. |

<p>I know that if I refresh, or if I clear my browser cache - I will see the most recent content. That's not my issue. What I want to understand is where this caching is coming from in the first place. </p>
<p>In the screenshot above, I see a 200 Status for most assets requested. Some assets though (like Google Fonts, Google Analytics, and wp.pixel.com) are not cached. </p>
<p>Is this entirely due to the browser's cache? It seems unusually aggressive if so. I've reached out to my host (WebHostingBuzz), but they are telling me "There is no caching in cPanel by default." </p>
<ul>
<li>I have seen this sporadic issue in Chrome, Firefox, and Safari (Mac). </li>
<li>I am using a Child Theme, based off of a <a href="https://themeforest.net/item/writsy-a-clean-faded-vintage-wordpress-blog-theme/16106738" rel="nofollow noreferrer">custom theme</a>.</li>
<li>I have some plugins installed, but no cache-related plugins installed.</li>
</ul>
<p>I've made direct changes to my child theme's style.css file on the server, and after a refresh - those changes appear instantly and successfully. </p>
<p>Refreshing always seems to retrieve the latest and most recent files/posts, but on occasion when returning to the site... I seem to be getting a cached view. And I'm unclear why. </p>
<p>I would appreciate any suggestions or advice on where to focus my troubleshooting. </p>

[Screenshot of Safari, Dev Tools](https://avoision.com/dev/whb/Screen%20Shot%202017-02-19%20at%206.17.44%20AM.png)
I know that if I refresh, or if I clear my browser cache - I will see the most recent content. That's not my issue. What I want to understand is where this caching is coming from in the first place.
In the screenshot above, I see a 200 Status for most assets requested. Some assets though (like Google Fonts, Google Analytics, and wp.pixel.com) are not cached.
Is this entirely due to the browser's cache? It seems unusually aggressive if so. I've reached out to my host (WebHostingBuzz), but they are telling me "There is no caching in cPanel by default."
* I have seen this sporadic issue in Chrome, Firefox, and Safari (Mac).
* I am using a Child Theme, based off of a [custom theme](https://themeforest.net/item/writsy-a-clean-faded-vintage-wordpress-blog-theme/16106738).
* I have some plugins installed, but no cache-related plugins installed.
I've made direct changes to my child theme's style.css file on the server, and after a refresh - those changes appear instantly and successfully.
Refreshing always seems to retrieve the latest and most recent files/posts, but on occasion when returning to the site... I seem to be getting a cached view. And I'm unclear why.
I would appreciate any suggestions or advice on where to focus my troubleshooting.
Thanks,
-Felix

Include this near the top of the header.php after the opening tag: `nocache_headers()`
From here: [Function Reference/nocache headers](https://codex.wordpress.org/Function_Reference/nocache_headers)
Run some tests, I believe this should only affect the main page file, other files should still cache normally.
More idealy, wordpress should be sending a last modified header with the home page. Hold on while I dig further into this.
Notice the cache-control max-age. As you can see, the cache has been set at 30 days. Meaning the browser will assume nothing has changed for 30 days unless the server sends a different header.

Emily | To clarify this, for anyone using Divi theme (but generally any WP theme), a simple inspection using Dev tools on the "head" for the stylesheet links usually gives a clue about the handle, as Den Isahac mentioned previously (it wasn't clear as he mentioned it can't be found).
**Anything before the "-css" on the ID of the link for the stylesheet of the Parent theme is generally that handle.**
Example below with Divi, id="divi-style-css" thus $handle = 'divi-style"
[](https://i.stack.imgur.com/kdPJU.jpg)
Thus for Divi, you would enqueue theme like this:
```
<?php
function my_theme_enqueue_styles() {
$parent_style = 'parent-style'; // This is 'twentyfifteen-style' for the Twenty Fifteen theme.
wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
wp_get_theme()->get('Version')
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
?>
```
Little bonus:
Browsers have an annoying tendency of caching the child stylesheet depending on its "Version". The drawback is that it prevents you from ever seeing your edits even after refreshing / clearing cache, unless you change the "Version" number in your css file after every edit.
You can change this behavior by swapping **wp\_get\_theme()->get('Version')** (the $ver parameter) for the handy **filemtime( get\_stylesheet\_directory() . '/style.css' )** instead, which adds a version number after the stylesheet corresponding to the timestamp from the last time you saved your child stylesheet, instead of the true "Version" declared in that stylesheet. You can eventually revert to the regular function before going live, but it can be extremely helpful during production.
The whole enqueue script for Divi would thus become:
```
<?php
function my_theme_enqueue_styles() {
$parent_style = 'divi-style'; // This is 'Divi' style referrence for the Divi theme.
wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style',
get_stylesheet_directory_uri() . '/style.css',
array( $parent_style ),
filemtime( get_stylesheet_directory() . '/style.css' )
);
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
?>

| In response to the [question asked here](https://wordpress.stackexchange.com/questions/257085/help-pinpointing-source-of-caching-issue) I find myself and this other user needing a solution to set a last modified header that contains the date and time of the most reicent post. Since we both in many themes have the home page set to a static page and then coding our dynamic content into the static files we are missing that important header to make sure cached homepages update when there are new posts.
So, how can we set a last modified HTTP header on a page that it set to the most recent Post? | Last-Modified header for visitors on the front-page
---------------------------------------------------
It's useful to see how the *Last-Modified* header is added to the feeds, in the [`wp::send_header()`](https://github.com/WordPress/WordPress/blob/55df308b4d4ea733a3738d8c210ffb0ab0d7d7bf/wp-includes/class-wp.php#L399) method.
If we want to be able to use `is_front_page()`, then the filters `wp_headers` or `send_header` are probably applied to early.
We could instead use the `template_redirect` hook to target the front-page, before the headers are sent and after `is_front_page()` is ready.
Here's an example:
```
/**
* Set the Last-Modified header for visitors on the front-page
* based on when a post was last modified.
*/
add_action( 'template_redirect', function() use ( &$wp )
{
// Only visitors (not logged in)
if( is_user_logged_in() )
return;
// Target front-page
if( ! is_front_page() )
return;
// Don't add it if there's e.g. 404 error (similar as the error check for feeds)
if( ! empty( $wp->query_vars['error'] ) )
return;
// Don't override the last-modified header if it's already set
$headers = headers_list();
if( ! empty( $headers['last-modified'] ) )
return;
// Get last modified post
$last_modified = mysql2date( 'D, d M Y H:i:s', get_lastpostmodified( 'GMT' ), false );
// Add last modified header
if( $last_modified && ! headers_sent() )
header( "Last-Modified: " . $last_modified . ' GMT' );
}, 1 );
```
Here we used the core PHP functions [`header()`](http://php.net/manual/en/function.header.php), [`headers_list()`](http://php.net/manual/en/function.headers-list.php) and [`headers_sent()`](http://php.net/manual/en/function.headers-sent.php) and the WordPress core function [`get_lastpostmodified()`](https://developer.wordpress.org/reference/functions/get_lastpostmodified/)
The *Etag* header could be added here too as the *md5* of the last modified date.
We can then test it from the command line with e.g.:
```
# curl --head https://example.tld
```
or just use the shorthand parameter `-I` to only fetch the HTTP headers. |
257,114 | <p>I'm trying to get a thumbnail for my post. Like if the first custom meta box doesn't have any <code>value/content</code>, should use <code>}else if ($img =get_post_custom_values('backdrop_img')) { $imgsrc = $img[0]; }</code> (which is the 2nd metabox) then 3rd, <code>else if</code> it also doesn't have any <code>content/value</code> just use an image from my theme directory.</p>

<pre><code>if($img = get_post_custom_values('featured_img')){ $imgsrc = $img[0];

| I'm trying to get a thumbnail for my post. Like if the first custom meta box doesn't have any `value/content`, should use `}else if ($img =get_post_custom_values('backdrop_img')) { $imgsrc = $img[0]; }` (which is the 2nd metabox) then 3rd, `else if` it also doesn't have any `content/value` just use an image from my theme directory.
But my problem is, it only works on the first meta box, which is:
```
if($img = get_post_custom_values('featured_img')){ $imgsrc = $img[0];
```
after that line the codes doesn't work and won't get values from 2nd custom meta box or use the defaul image if nothing from the conditions work.
I'm new to php and stil learning so i'm still confused. I'd appreciate any help.
So here's my code so far.
UPDATED: with the entire test code of the loop.
```
<?php $year = date ("Y"); query_posts(array(get_option('year') => $year, 'posts_per_page' => 5, 'showposts' => 5)); ?>
<?php while (have_posts()) : the_post(); ?>
<?php if (has_post_thumbnail()) {
$imgsrc = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID),'medium');
$imgsrc = $imgsrc[0];
} elseif ($postimages = get_children("post_parent=$post->ID&post_type=attachment&post_mime_type=image&numberposts=0")) {
foreach($postimages as $postimage) {
$imgsrc = wp_get_attachment_image_src($postimage->ID, 'medium');
$imgsrc = $imgsrc[0];
}
} elseif (preg_match('/<img [^>]*src=["|\']([^"|\']+)/i', get_the_content(), $match) != FALSE) {
$imgsrc = $match[1];
} else {
if($img = get_post_custom_values('featured_img')){
$imgsrc = $img[0];
}elseif($img = get_post_custom_values('backdrop_img')){
$imgsrc = $img;
} else {
$img = get_template_directory_uri().'/movies/no_img.png';
$imgsrc = $img;
}
} ?>
<div class="post_content">
<img src="<?php echo $imgsrc; $imgsrc = ''; ?>
<a href="<?php the_permalink() ?>" class="slide-link" title="<?php the_title(); ?>"><?php the_title(); ?></a>
<p class="sc-desc"> <?php the_excerpt(); ?></p>
</div>
<?php } endwhile; ?>

257,153 | <p>I'm at a loss.. </p>
<p>I wanna check the current users post count. If the post count is 1, the user should be redirected. I have tested the following code:</p>
<pre><code>add_action( 'template_redirect', 'redirect_to_specific_page' );
function redirect_to_specific_page() {
$current_user = wp_get_current_user();
if (empty($the_user_id)) {
$the_user_id = $current_user->ID;
}
$user_post_count = count_user_posts( $the_user_id );
if ( is_page('butiktest') && $user_post_count == 1 ) {
wp_redirect( 'enhytte', 301 );
exit;
}
}
</code></pre>
<p>However, the above code will redirect no matter the amount of posts.</p>
<p>What am I doing wrong?</p>
<p>EDIT: After pointing out my syntax error was a missing "=", it is still not working.</p>
<p>EDIT 2: The code is in theory working, however, once a post is added, the <code>user_post_count</code> is not updated, and stays at the previous value. </p>
<p>EDIT3: count_user_posts only count published posts, how do I check for 'pending' and 'draft'?</p>

| I'm at a loss..
I wanna check the current users post count. If the post count is 1, the user should be redirected. I have tested the following code:
```
add_action( 'template_redirect', 'redirect_to_specific_page' );
function redirect_to_specific_page() {
$current_user = wp_get_current_user();
if (empty($the_user_id)) {
$the_user_id = $current_user->ID;
}
$user_post_count = count_user_posts( $the_user_id );
if ( is_page('butiktest') && $user_post_count == 1 ) {
wp_redirect( 'enhytte', 301 );
exit;
}
}
```
However, the above code will redirect no matter the amount of posts.
What am I doing wrong?
EDIT: After pointing out my syntax error was a missing "=", it is still not working.
EDIT 2: The code is in theory working, however, once a post is added, the `user_post_count` is not updated, and stays at the previous value.
EDIT3: count\_user\_posts only count published posts, how do I check for 'pending' and 'draft'? | Thanks everyone for all the help! I really appreciate it. I was able to make it work by removing `[0]` in `$imgsrc = $img[0];` and using `custom_get_meta()`
like:
`$img = post_movie_get_meta('featured_img')`
and:
`$img = post_movie_get_meta('backdrop_img')` |
257,189 | <p>So right now the site automatically creates pages when a post is updated. I want this page to include an audio playlist. So what I do, is simply add the shortcode: <code>[playlist]</code>.
Then, when the audio files are attached to the page, the playlist automatically generates.</p>
<p>I can confirm that this method works with specified IDs.</p>
<p><strong>The problem is</strong>, that 3 different pages are made, and I need the audio to be attached to all three pages. So my solution is that I make a another page, set the audio files as children to that page, and make the original 3 pages children of the new page. Then I could use the <code>[playlist]</code> shortcode, but tell it to get the id from the parent page.</p>
<p><strong>Example:</strong></p>
<pre><code>[playlist id="<?php get_parent_id ?>"]
</code></pre>
<p>or something like this.</p>
<p>The problem is that I cannot get the parent id. I've tried multiple different lines of code and nothing will work. The playlist just gets the default 0 ID, which it does when <code>id=""</code> is left blank.</p>
<p>This is all going into the <code>functions.php</code> file in my theme's directory.</p>
<p>--</p>
<p>Maybe there is a better way to do this, thusfar, this seems like the simplest solution, if only I can get the direct parent ID. It must exist.</p>

How to get images into your new website anyway
==============================================
So if you're only exporting and importing posts, one option is to move your images manually. But that's potentially a lot of work, especially on larger sites. The other option is to import you posts without the images, and then use the [Auto Upload Images plugin](https://wordpress.org/plugins/auto-upload-images/) to add the images afterwards. This plugin does several things:

--------------------------------------------------------------------------------------------------------------------------------
**Step 1: Prepare your export file on the old site**

Final thoughts
==============
Probably a good idea to make a backup of your new site first (at least of your site's database).
At the time of writing the Auto Upload Images plugin hasn't been updated for quite some time, but on testing it worked fine.
With this method all images in posts get imported, not just featured images. |
257,227 | <p>I created a custom post type for WP, that should just be visitable for user that have a custom capability <code>read_cpt</code>. Within templates and <code>pre_get_posts</code> I can run checks to include or exclude the CPT by using <code>current_user_can()</code>.</p>
<p>I don't want the CPT, not even the endpoint, to show up within the REST API, to keep it top secret, as long as a user doesn't have the custom capability.</p>

'has_archive' => false,
'exclude_from_search' => true,
'publicly_queryable' => false,
'show_in_rest' => false,
);
register_post_type( 'cpt', $args );
}
add_action( 'init', 'add_post_type', 0 );

<p>and separately add it to the REST API:</p>
<pre><code>add_action( 'init', 'cpt_rest_support', 25 );
function cpt_rest_support() {
global $wp_post_types;
if ( current_user_can( 'read_addresses' ) ) {
//be sure to set this to the name of your post type!
$post_type_name = 'address';
if( isset( $wp_post_types[ 'cpt' ] ) ) {
$wp_post_types[ 'cpt' ]->show_in_rest = true;
}
}
}
</code></pre>
<p>By creating a custom <code>WP_REST_Posts_Controller</code> class I couldn't find a way to hide the endpoint by modifying any of the <code>*_permissions_check</code></p>
<p>Is there something like a "show_in_rest_permition_check" argument for <code>register_post_type()</code> or is the described way the only method?</p>

I don't want the CPT, not even the endpoint, to show up within the REST API, to keep it top secret, as long as a user doesn't have the custom capability.
The only way I could figure out to hide the endpoints in the API to run this code.
Register post type for "classic" WP:
```
function add_post_type() {
$args = array(
[...]
'public' => false,
'has_archive' => false,
'exclude_from_search' => true,
'publicly_queryable' => false,
'show_in_rest' => false,
);
register_post_type( 'cpt', $args );
}
add_action( 'init', 'add_post_type', 0 );
```
and separately add it to the REST API:
```
add_action( 'init', 'cpt_rest_support', 25 );
function cpt_rest_support() {
global $wp_post_types;
if ( current_user_can( 'read_addresses' ) ) {
//be sure to set this to the name of your post type!
$post_type_name = 'address';
if( isset( $wp_post_types[ 'cpt' ] ) ) {
$wp_post_types[ 'cpt' ]->show_in_rest = true;
}
}
}
```
By creating a custom `WP_REST_Posts_Controller` class I couldn't find a way to hide the endpoint by modifying any of the `*_permissions_check`
Is there something like a "show\_in\_rest\_permition\_check" argument for `register_post_type()` or is the described way the only method? | The REST API has no parameters, options to solve this - in my opinion. But you should register only if the users have the capability in his role, like the follow example.
```
add_action( 'rest_api_init', function() {
// Exit, if the logged in user have not enough rights.
if ( ! current_user_can( 'edit_posts' ) ) {
return;
}
// Register Meta Data.
register_meta( 'post', 'foo', array(
'show_in_rest' => true,
));
});
```
That's fire the custom data in the REST API only, if the user have enough rights, capabilities in his role. My `register_meta()` is only an example, that should also work with your additional parameter for `register_post_type`, like `$wp_post_types[ 'cpt' ]->show_in_rest = true;`. |

loading JavaScript asynchronously will cause several issues with dependencies:

function js_async_attr($tag){
//Add async to all scripts tags

257,240 | <p>I'm loading a list of products on an archive type page and creating a custom query to do so. I want to create a 'load more' functionality so that clicking the 'load more' button at the bottom of list loads the next 10 products.</p>
<p>I thought it would be as easy as using a variable to set 'posts_per_page' and simply increment it by 10 when the button is clicked. I get strange results however. This code is not the final code but just to illustrate this problem.</p>

<p>So the first time this is loaded it resolves to false because the button hasny't yet been clicked, so posts_per_page will be set to 5. Then when clicking the button, you would expect 10 to load but for some reason it continues to load 5. If however I change the code to this:</p>
<pre><code>if(isset( $_POST['load-next-amount'] )){
$pageamount = 4
}
else {
$pageamount = 5;

<p>it will load 4. So I cannot increase the amount of posts_per_page through this variable, but I can decrease it. Strange.</p>
<p>Here is my query:</p>
<pre><code>$myArgs = array(

| I have problem in Wordpress after migrating my website.
In title tag (`<title>`) I have
`"–"`
instead of
`"-"`
For the browser it's good, in the title it shows good.
But in html code is `"–"`....
Please help me <3 | Background:
===========
WordPress converts normal dash (-) to long dash (`–`), straight quotes to curly quotes and some other similar symbols and punctuations to their printer friendly versions using `wptexturize`.
Generally it's recommended to leave them up to WordPress. However, occasionally, we may want to override this behaviour. For example, in case we are writing Programming CODE or command and want people to copy paste them.
Solution:
=========
One way to avoid this conversion is to have these CODE inside `<code></code>` block. That way WordPress will know that they are meant to be kept as is. However, we may have already written it and don't want a rewrite. In that case, it's possible to stop WordPress to do these auto conversions all together by disabling `wptexturize`.
For WordPress 4.0 and above, it's easy to do using the following CODE in a plugin or your theme's `functions.php` file:
```
add_filter( 'run_wptexturize', '__return_false' );
```
For before WordPress 4.0, you'll need a little more CODE:
```
foreach( array(
'bloginfo',
'the_content',
'the_excerpt',
'the_title',
'comment_text',
'comment_author',
'link_name',
'link_description',
'link_notes',
'list_cats',
'nav_menu_attr_title',
'nav_menu_description',
'single_post_title',
'single_cat_title',
'single_tag_title',
'single_month_title',
'term_description',
'term_name',
'widget_title',
'wp_title'
) as $texturize_disable_for )
remove_filter( $texturize_disable_for, 'wptexturize' );
```
Of course, you may choose to disable `wptexturize` only for part of your content. Say, to disable only for `title`, you may use:
```
remove_filter( 'the_title', 'wptexturize' );
``` |

| I want to include inline SVGs in a metabox textarea.
That's easy. What's killing me is how do I sanitize the textarea before saving the postmeta, and how do I escape it?
Halp?
Thanks! | Here is a PHP library that was created for sanitizing SVG files that may be worth looking into. <https://github.com/darylldoyle/svg-sanitizer>
Here is an example of how this could be used:
```
// Now do what you want with your clean SVG/XML data
function your_save_meta( $post_id, $post, $update ) {
// - Update the post's metadata.
if ( isset( $_POST['svg_meta'] ) ) {
// Load the sanitizer. (This path will need to be updated)
use enshrined\svgSanitize\Sanitizer;
// Create a new sanitizer instance
$sanitizer = new Sanitizer();
// Pass your meta data to the sanitizer and get it back clean
$cleanSVG = $sanitizer->sanitize($_POST['svg_meta']);
// Update your post meta
update_post_meta( $post_id, 'svg_meta_name', $cleanSVG );
}
}
add_action( 'save_post', 'your_save_meta', 10, 3 );

257,281 | <p>I am working on a WordPress child theme where I do not have access to any markup other than the header.php. (I have access to child functions.php and the style.css)</p>

Absolutely. Almost everything is possible. But you're going to have to do something a little hackish.
The `the_content` filter doesn't actually filter the content of the entire page. That particular filter is used throughout WordPress to filter a variety of different contents.
Unfortunately, there isn't a good way to filter the entire page.
One way to accomplish this would be to use `ob_start()` and `ob_get_clean()` attached to appropriate hooks. We need to hook into before anything is output to the page and start an output buffer. Then we need to hook in at the last possible moment and get the buffer.
Then we can do something with the content. Your regex was close, but not quite right.
In your functions.php, add the following:
```
//* Hook into WordPress immediately before it starts output
add_action( 'wp_head', 'wpse_wp', -1 );
function wpse_wp() {
//* Start out buffering
ob_start();
//* Add action to get the buffer on shutdown
add_action( 'shutdown', 'wpse_shutdown', -1 );
}
function wpse_shutdown() {
//* Get the output buffer
$content = ob_get_clean();
//* Do something useful with the buffer
//* Use preg_replace to add a <section> wrapper inside the <body> tag
$pattern = "/<body(.*?)>(.*?)<\/body>/is";
$replacement = '<body$1><section class="new-master">$2</section></body>';
//* Print the content to the screen
print( preg_replace( $pattern, $replacement, $content ) );
}
```

It depends. A better, faster way to accomplish this would be to edit the template files. Since you state that you don't have access to the template files, then I believe that something like this would be your only option. |
257,284 | <p>I'm displaying three posts (custom post types) with a foreach loop, each displaying an audio player and some metadata.

| I want to use jquery in my admin side programming but it seems there's no jquery loaded in the page at all and it load only at main website! Has my wordpress any problem which can't load jquery or I should do something extra to do it. However I put this code in function.php, but it not works:
```
if(is_admin()){
function load_admin_script(){
wp_enqueue_script('jquery_script', "/wp-includes/js/jquery/jquery.js");
}
add_action('admin_enqueue_scripts','load_admin_script');
}
``` | If you want to load Jquery, wordpress already provides a handler for it (its also the one in `/wp-includes/js/jquery/jquery.js`):
```
function load_admin_script(){
wp_enqueue_script('jquery');
}
add_action('admin_enqueue_scripts','load_admin_script');
```
note that the jQuery in WordPress runs in noConflict mode. |
257,317 | <p>I run WordPress version 4.7.2. and it uses jQuery version 1.12. I need to update this version to a higher one. I replaced it with a new version before, but when I upgrade WordPress core it is replaced with 1.12 again.
How can I change the version of jQuery that WordPress uses permanently?</p>

If you are sure that you want to change the core `jQuery` version, in that case you may add the following CODE in your active theme's `functions.php` file (even better if you create a plugin for this):
```
function replace_core_jquery_version() {
wp_deregister_script( 'jquery' );
// Change the URL if you want to load a local copy of jQuery from your own server.
wp_register_script( 'jquery', "https://code.jquery.com/jquery-3.1.1.min.js", array(), '3.1.1' );
}
add_action( 'wp_enqueue_scripts', 'replace_core_jquery_version' );
```
This will replace core `jQuery` version and instead load version `3.1.1` from Google's server.
Also, although ***not recommended***, you may use the following additional line of CODE to replace the jQuery version in `wp-admin` as well:
```
add_action( 'admin_enqueue_scripts', 'replace_core_jquery_version' );
```
This way, even after updating WordPress, you'll have the version of `jQuery` as you want.
A slightly better function:
===========================
The `replace_core_jquery_version` function above also removes `jquery-migrate` script added by WordPress core. This is reasonable, because the newest version of jQuery will not work properly with an older version of `jquery-migrate`. However, you can include a newer version of `jquery-migrate` as well. In that case, use the following function instead:
```
function replace_core_jquery_version() {
wp_deregister_script( 'jquery-core' );
wp_register_script( 'jquery-core', "https://code.jquery.com/jquery-3.1.1.min.js", array(), '3.1.1' );
wp_deregister_script( 'jquery-migrate' );
wp_register_script( 'jquery-migrate', "https://code.jquery.com/jquery-migrate-3.0.0.min.js", array(), '3.0.0' );
}

| Since plugin updates might bring some unexpected issues to the compatibilies.
Is it recommended to modify plugin version value
to fool the wordpress plugin update system if priority is to turn off plugin out-of-date warnings from wordpress backend ? | >
> ***Warning:*** You shouldn't replace core jQuery version, **especially in the admin panel**. Since many WordPress core functionality may depend on the version. Also, other plugin may depend on the `jQuery` version added in the core.
>
>
>
If you are sure that you want to change the core `jQuery` version, in that case you may add the following CODE in your active theme's `functions.php` file (even better if you create a plugin for this):
```
function replace_core_jquery_version() {
wp_deregister_script( 'jquery' );
// Change the URL if you want to load a local copy of jQuery from your own server.
wp_register_script( 'jquery', "https://code.jquery.com/jquery-3.1.1.min.js", array(), '3.1.1' );
}
add_action( 'wp_enqueue_scripts', 'replace_core_jquery_version' );
```
This will replace core `jQuery` version and instead load version `3.1.1` from Google's server.
Also, although ***not recommended***, you may use the following additional line of CODE to replace the jQuery version in `wp-admin` as well:
```
add_action( 'admin_enqueue_scripts', 'replace_core_jquery_version' );
```
This way, even after updating WordPress, you'll have the version of `jQuery` as you want.
A slightly better function:
===========================
The `replace_core_jquery_version` function above also removes `jquery-migrate` script added by WordPress core. This is reasonable, because the newest version of jQuery will not work properly with an older version of `jquery-migrate`. However, you can include a newer version of `jquery-migrate` as well. In that case, use the following function instead:
```
function replace_core_jquery_version() {
wp_deregister_script( 'jquery-core' );
wp_register_script( 'jquery-core', "https://code.jquery.com/jquery-3.1.1.min.js", array(), '3.1.1' );
wp_deregister_script( 'jquery-migrate' );
wp_register_script( 'jquery-migrate', "https://code.jquery.com/jquery-migrate-3.0.0.min.js", array(), '3.0.0' );
}

Rather than reading the option, setting up a conditional, and checking for the presence or absence of a value, we can use the WordPress `checked` function. |

Is it possible to use pages in this way with Wordpress? I had a look online and on this site but I haven't been able to find a solution for this problem. | WordPress doesn't load templates that way.
First: give the template a name:
================================
To load a page template, first you'll have to make sure your template has a name. To do that, you'll have to have the following CODE in your template file (here `mypage.php`):
```
<?php
/**
* Template Name: My Page
*/
```
Once you have the above PHP comment, WordPress will recognise it as a template file.
Then, assign the template to a page:
====================================
Now you'll have to create a WordPress `page` (from `wp-admin`).
While you create the `page`, WordPress will give you the option to choose a custom template (if there is one). After you choose the template and `Publish`, that page will use your `mypage.php` file as a template.

257,403 | <p>I have a partial that I call around the website at various points. This partial simply displays the latest Post.</p>
<p>It looks like so:</p>
<pre><code><?php
$args = array(
'posts_per_page' => 1,
'order' => 'desc'
);
query_posts($args);
if ( have_posts() ) :
while ( have_posts() ) : the_post();
if (has_post_thumbnail( $post->ID ) ){
$featured_image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'home-news-thumbnail' );
}
?>
<a href="<?php echo get_the_permalink(); ?>"><h3><?php echo get_the_title(); ?></h3></a>
<?php if(!empty($featured_image)): ?>
<a href="<?php echo get_the_permalink(); ?>">
<img src="<?php echo $featured_image[0]; ?>" alt="" width="250" class="pull-left">
</a>
<?php endif; ?>
<p>
<?php echo get_the_excerpt(); ?>
</p>
<a href="<?php echo get_the_permalink(); ?>" class="btn btn-brand-dark">more</a>
<div class="clearfix"></div>
<?php
endwhile;
endif;
wp_reset_postdata();
?>
</code></pre>
<p>This works fine until I 'Sticky' a post. Then I get 2 posts instead of 1.</p>
<p>How can I amend all queries so that <code>posts_per_page</code> has the requested number of posts, regardless of sticky posts?</p>
<p>So in the example above, I'm currently getting <strong>2</strong> posts (despite requesting 1), but I want the latest post, whether that's a sticky post or not.</p>
<p>I know about <code>ignore_sticky_posts</code> parameter, but that will ignore the sticky post, which I don't want to do. If there's a sticky post it should be first.</p>

This works fine until I 'Sticky' a post. Then I get 2 posts instead of 1.
How can I amend all queries so that `posts_per_page` has the requested number of posts, regardless of sticky posts?
So in the example above, I'm currently getting **2** posts (despite requesting 1), but I want the latest post, whether that's a sticky post or not.
I know about `ignore_sticky_posts` parameter, but that will ignore the sticky post, which I don't want to do. If there's a sticky post it should be first. | Here's a way to force the exact `posts_per_page` value in `WP_Query`, regardless of sticky posts or custom post injects:
```
$args = [
'posts_per_page' => 1,
'_exact_posts_per_page' => true // <-- our custom input argument
];
```
by using our custom `_exact_posts_per_page` input argument.
I'm sure this has been implemented many times before, but I didn't find it at the moment, so let us try to implement it with this demo plugin:
```
<?php
/**
* Plugin Name: Exact Posts Per Pages
* Description: Activated through the '_exact_posts_per_page' bool argument of WP_Query
* Plugin URI: http://wordpress.stackexchange.com/a/257523/26350
*/
add_filter( 'the_posts', function( $posts, \WP_Query $q )
{
if(
wp_validate_boolean( $q->get( '_exact_posts_per_page' ) )
&& ! empty( $posts )
&& is_int( $q->get( 'posts_per_page' ) )
)
$posts = array_slice( $posts, 0, absint( $q->get( 'posts_per_page' ) ) );
return $posts;
}, 999, 2 ); // <-- some late priority here!
```
Here we use the `the_posts` filter to slice the array, no matter if it contains sticky posts or not.
The `the_posts` filter is not applied if the `suppress_filters` input argument of `WP_Query` is `true`.
**Note** that `query_posts()` is not recommended in plugins or themes. Check out the many warnings in the *Code reference* [here](https://developer.wordpress.org/reference/functions/query_posts/).
Hope you can test it further and adjust to your needs! |

1. Why doesn't the paragraph of "Hello" show up on the form? Is it because widget form prevent it from doing so?
2. I also heard about Backbone.js that refreshes the front-end, but I am not sure if that will work.

``` | Thank you **Dave Romsey** and **Mark Kaplun** for pointing out about not using HTML ID in WordPress Widget. I finally find a solution for my need.
**Solution:**
We need to add a preset variables into all of the 3 functions (widget, form, update). In my codes, they are called "spotlight\_image\_link1, spotlight\_image\_link2, etc". Then in the "form function" give their id using php code. Please read my code below for more information.
**What can my solution do?**
Basically, it is not fully dynamic because we need to predefine all the spotlights beforehand. In my case, I only predefined two spotlights to make the code simple to read.
**Here what it looks like:**
[](https://i.stack.imgur.com/Z6oZD.png)
**Logic behind the scene:**
* whenever the "Click me!" button is clicked, a spotlight will be added.
* There is a tracker array called "tracker" that keep track of which predefined spotlights are already used. When all spotlights are used, disable the "Click me!" button.
* When the "delete spotlight" is clicked, remove that specific spotlight, and re-enable the "Click me!" button. Note that the name of each delete button is append with number. This lets us know which spotlight to be deleted.
* The spotlight is saved only if and only if the input is not empty. That condition is in the "while" loop of the "form" function.
**Limitation:**
As of now, whenever, we clicked "Save", the spotlight order is rearranged from 1 to n. It's not super user-friendly, but I plan to use Ajax to sync the front-end to the back-end. I am not sure how just yet.
**Source code:**
* As of WordPress 4.7.2, it works without any error.
* Put all the source code into "repeat.php" file in your plugin directory. If you don't know how, please google it.

| I have my blogs on `wordpress.com` (e.g. `test.wordpress.com`). I want to migrate all those blogs to my self hosted WordPress website. Is this possible?
Is there any plugin in WordPress or do I need to develop any API? | Thank you **Dave Romsey** and **Mark Kaplun** for pointing out about not using HTML ID in WordPress Widget. I finally find a solution for my need.
**Solution:**
We need to add a preset variables into all of the 3 functions (widget, form, update). In my codes, they are called "spotlight\_image\_link1, spotlight\_image\_link2, etc". Then in the "form function" give their id using php code. Please read my code below for more information.
**What can my solution do?**
Basically, it is not fully dynamic because we need to predefine all the spotlights beforehand. In my case, I only predefined two spotlights to make the code simple to read.
**Here what it looks like:**
[](https://i.stack.imgur.com/Z6oZD.png)
**Logic behind the scene:**
* whenever the "Click me!" button is clicked, a spotlight will be added.
* There is a tracker array called "tracker" that keep track of which predefined spotlights are already used. When all spotlights are used, disable the "Click me!" button.
* When the "delete spotlight" is clicked, remove that specific spotlight, and re-enable the "Click me!" button. Note that the name of each delete button is append with number. This lets us know which spotlight to be deleted.
* The spotlight is saved only if and only if the input is not empty. That condition is in the "while" loop of the "form" function.
**Limitation:**
As of now, whenever, we clicked "Save", the spotlight order is rearranged from 1 to n. It's not super user-friendly, but I plan to use Ajax to sync the front-end to the back-end. I am not sure how just yet.
**Source code:**
* As of WordPress 4.7.2, it works without any error.
* Put all the source code into "repeat.php" file in your plugin directory. If you don't know how, please google it.
**repeat.php**

| I'm using a function to filter the\_title, adding a string onto the end, but would also like to return the original title, unfiltered on the same page. Is there a way to get the title without it being filtered? | There's a few ways to do this, but I would argue that the preferred way is, in general, fetching the `post_title` attribute from the post object. This does not depend on removing all filters for a certain function and adding them back later — the latter requires you to directly access the global `$wp_filter`.
[`get_post`](https://codex.wordpress.org/Function_Reference/get_post) retrieves the post object for a post ID, and the post object, on construction, populates all post fields with the fields from the database, without applying any filtering.
Thus, your code would simply be
```
$title = get_post( $post_id )->post_title;
```
If the post with ID `$post_id` is not guaranteed to exist, be sure to check whether the returned value from `get_post` is a post object.
NB another approach is to use `get_post_field( 'post_title', $post_id )`, which by default only has the filter `'post_title'` applied to it (and not the `the_title` filter). However, as @PatJ kindly pointed out, using the optional `$context` parameter, you can get the raw value using the context `"raw"`:
```
get_post_field( 'post_title', $post_id, 'raw' );

What I'm using to call the function.

The issue I am running into is $post is giving me the previous post information, however, when I pass that into get\_the\_excerpt it returns the current post excerpt rather than the previous post excerpt.
EDIT
Changed function to this after several people told me I can just pass the $post\_id to get\_the\_excerpt()
```

function excerpt($num, $post_id = '') {

$excerpt = explode(' ', $excerpt, $limit);
array_pop($excerpt);
$excerpt = implode(" ",$excerpt)."…";

Another solution - using `setup_postdata($post);` and `wp_reset_postdata();`
```
function custom_get_the_excerpt($post_id) {
global $post;
$save_post = $post;
$post = get_post($post_id);

| I've always used @import for the css in my child-theme which i'm now told is bad practice.
What is the best way to set up a child theme going forward? The latest solution on the wordpress codex seems really complex / highly confusing?
There must be a way to do a relatively simple enqueue in my child-theme's functions.php surely?
Any help would be awesome. I feel completely lost / useless trying to find any succinct info on this.
Emily | The code that is in [codex](https://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme) for queuing the style of the parent theme instead of using `@import`, is not well commented, so i will comment it more, so you have this:
```
<?php
function my_theme_enqueue_styles() {
$parent_style = 'parent-style';
wp_enqueue_style($parent_style, get_template_directory_uri() . '/style.css');
wp_enqueue_style('child-style',
get_stylesheet_directory_uri() . '/style.css',
array($parent_style),
wp_get_theme()->get('Version')
);
}
add_action('wp_enqueue_scripts', 'my_theme_enqueue_styles');
?>
```
1.- line:
```
$parent_style = 'parent-style';
```
this is literally a string name that you are giving to the theme stylesheet, it will be the `$handle` of the stylesheet you are queuing, it can be what you want, by example `'divi-style'`, in the `HTML` it will be used as the `ID` like this `<link rel="stylesheet" id="divi-style" ...`
2.- line:
```
wp_enqueue_style($parent_style, get_template_directory_uri() . '/style.css');
```
its registering the stylesheet and queuing it, when its registering it, it will use the name of the first parameter in this case it will be `'parent-style'`, also its using `get_template_directory_uri()` to get the path to the `parent theme` stylesheet.
3.- line:
```
wp_enqueue_style('child-style',
get_stylesheet_directory_uri() . '/style.css',
array($parent_style),
wp_get_theme()->get('Version')
);
```
this is registering and queuing the child theme stylesheet (the current theme stylesheet), this is the usual procedure for a theme, each parameter its already explained [here](https://developer.wordpress.org/reference/functions/wp_enqueue_style/), for the example:
* `'child-style'` - this is the name of this stylesheet the `$handle`
* `get_stylesheet_directory_uri() . '/style.css'` - this is the path to
the stylesheet file.
* `array($parent_style)` - this is the array of stylesheets that we need
to run before our stylesheet runs we cant put actual paths that is
why we name them with a `$handle`, in this case we need the parent stylesheet to run first (its a dependency)
* `wp_get_theme()->get('Version')` - this is the number version that
will be at the end of the stylesheet `URL` like this `/style.css?ver=1.0`, this is for cache purposes, the standard is that you update the version so the latest file is loaded and not a cached version, you dont want to change that number in all the files where you use it right? so use `wp_get_theme()->get('Version')` it will get the version that is in your `style.css` file (not the parent one).
so if you want the resumed version it will be like this:
```
<?php
function my_theme_enqueue_styles() {
//load the parent stylesheet
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
//load the child stylesheet but after the parent stylesheet
wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array( 'parent-style' ));
}
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
?>

As you can see on the screenshot ABOVE (which is taken on view-source:), it the correct selected input is CHECKED already however even if it's check you can see on the screenshow BELOW that it doesn't display as checked.
[](https://i.stack.imgur.com/UP1zH.png)
It's already checked but not displaying , i dont know | In the WordPress back-end you have to use `checked="checked"` (stricter XHTML), because the CSS will not be applied otherwise:
```
<input type="radio" name="colors" id="blue" checked="checked">
```
this is the CSS that applies the blue dot:
[](https://i.stack.imgur.com/4PD06.png)
WordPress already provides a function for this [checked()](https://developer.wordpress.org/reference/functions/checked/)
```
<input type="radio" name="colors" id="blue" <?php checked( 'red', get_option( 'color' ) ); ?> />
```
so you dont have to do an `If` and `echo`. |

```
RewriteRule ^[0-9]+/[0-9]+/(.*)\.html$ /$1 [R=301,L]

I am searching for the solution from last 2 days, but no luck! | The Problem:
============
As [Mark suggested already](https://wordpress.stackexchange.com/a/257666/110572), your template loading by manipulating cache is far from standard practice. With these sort of cache alteration, even if you modify your CODE to work with WordPress `4.7+`, there is no guarantee that you'll not find similar problems in future updates. So better use any of the solutions mentioned below:
Theme Solution:
===============
Instead of assigning templates form a plugin, you can have actual [page templates](https://developer.wordpress.org/themes/template-files-section/page-templates/) in the active theme. Your active theme is the **recommended** place to have these page templates.
Plugin Solution
===============
However, if you have to assign these templates with your plugin for some reason, then use the [`theme_page_templates`](https://developer.wordpress.org/reference/hooks/theme_page_templates/) hook to do so. It'll work for WordPress `4.4+`.
Following is the rewrite of your CODE using `theme_page_templates` filter hook:
```
function get_my_template( $template ) {
$post = get_post();
$page_template = get_post_meta( $post->ID, '_wp_page_template', true );
if( $page_template == 'templates/study_home.php' ){
return plugin_dir_path(__FILE__) . "templates/study_home.php";
}
if( $page_template == 'templates/study_job_home.php' ){
return plugin_dir_path(__FILE__) . "templates/study_job_home.php";
}
if( $page_template == 'templates/exams.php' ){
return plugin_dir_path(__FILE__) . "templates/exams.php";
}
if( $page_template == 'templates/colleges.php' ){
return plugin_dir_path(__FILE__) . "templates/colleges.php";
}
return $template;
}
function filter_admin_page_templates( $templates ) {
$templates['templates/exams.php'] = __('Exams');
$templates['templates/colleges.php'] = __('Colleges');
$templates['templates/study_home.php'] = __('Study Home');
$templates['templates/study_job_home.php'] = __('Study Job Home');
return $templates;
}
function add_my_templates() {
if( is_admin() ) {
add_filter( 'theme_page_templates', 'filter_admin_page_templates' );
}
else {
add_filter( 'page_template', 'get_my_template', 1 );
}
}
add_action( 'wp_loaded', 'add_my_templates' );
```
Use the above CODE instead of the CODE you've provided. It'll work for any WordPress version `4.4` and later. I've tested it for WordPress `4.7.2` & it works fine. |

| I've been looking and looking for a solution for my problem but i have been unable to find anything.
I have found a plugin that allow me to restrict certain usernames, I found even a function but there is nothing that allows me to restrict partially matching usernames, there is nothing to prevent users to register under names like "joeadmin" or "seanadmin" and etc.
Is there anything that can be done to prevent users to register anything that contain "admin" and other prohibited words? | There's a [`validate_username`](https://developer.wordpress.org/reference/hooks/validate_username/) filter hook that is used by [`validate_user()`](https://developer.wordpress.org/reference/functions/validate_username/) which is in turn used by [`register_new_user()`](https://developer.wordpress.org/reference/functions/register_new_user/).
So you can disallow usernames containing `admin` or other prohibited terms:
```
add_filter( 'validate_username', 'wpse257667_check_username', 10, 2 );
function wpse257667_check_username( $valid, $username ) {
// This array can grow as large as needed.
$disallowed = array( 'admin', 'other_disallowed_string' );
foreach( $disallowed as $string ) {
// If any disallowed string is in the username,
// mark $valid as false.
if ( $valid && false !== strpos( $username, $string ) ) {
$valid = false;
}
}
return $valid;
}
```
You can add this code to your theme's `functions.php` file or (preferably) [make it a plugin](https://codex.wordpress.org/Writing_a_Plugin).

| Say you have 4 example domains:
1. dogsrule.com
2. dogsrule.cn
3. dogsrulecatsdrool.co.uk
4. dogsrule.au
Currently, each are their own WordPress sites hosted on the same server. Each are only 2 pages, the homepage which includes a form, and a thank you page.

Can we have a single normal WordPress install with custom pages for each site that all 4 domains points to respectively? | Why not multisite:
==================
* Multisite installations are difficult to maintain compared to single site installations.
* Many useful plugins don't work properly on multisite installations.
* There may be SEO concern for such short web sites with basically just one page (thank you page doesn't count) that looks very similar from the names. Multisite won't solve this probable issue.

Why not single site:
====================
* Managing multiple languages may not be easy in a single site installation if you haven't done that before.
As @Mark suggested in the comment, if you have different language contents in those sites (again just assumption based on example domain names), merging them into a single site may not be easy. You are encouraged to use plugins such as [Polylang](https://wordpress.org/plugins/polylang/) to manage multiple languages. There are thousands of multilingual sites out there running perfectly fine with WordPress. However, if it turns out to be difficult, then you may consider setting up Multisite or even keeping it as it is.
Leave them as they are?
=======================
If the following conditions are true, then may be it's better to just leave them as they are:
* Managing these multiple separate installations are not too difficult for you.
* You may have plugins that are not well tested in multisite installations.
* You have multilingual content in different sites and you have no experience with WordPress multilingual setup.
Steps for single site installation
==================================
If you decide to go for single site installation, or at least want to test it, you may follow the steps below:
1. Keep any one site (for example `dogsrule.com`) as the main site.
2. Then make the other three sites point to the main site's web root directory.
3. The main site's home page remains as is & then you create three more pages for the other three sites (for example: `dogsrule.com/cn`, `dogsrule.com/dogs-rule-cats-drool` and `dogsrule.com/au`).
4. Then you may use server rewrite rules to redirect other three domains to the corresponding pages of the main site.
For example, if your web server is Apache, then in your main site's `.htaccess` file you may use the following CODE (according to the above pages):
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# redirect rules for the other three domains
RewriteCond %{HTTP_HOST} ^dogsrule\.cn$
RewriteRule . http://dogsrule.com/cn [R=301,L]
RewriteCond %{HTTP_HOST} ^dogsrulecatsdrool\.co\.uk$
RewriteRule . http://dogsrule.com/dogs-rule-cats-drool [R=301,L]
RewriteCond %{HTTP_HOST} ^dogsrule\.au$
RewriteRule . http://dogsrule.com/au [R=301,L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
```
After this you'll have just one site with four main pages (including the home page) and four thank you pages and your other domains will correctly redirect to the corresponding pages.
>
> ***Note:*** You may remove the other three sites after setting up the above, **but don't delete the domains.** Even though, effectively you'll only have one site after this, however, if you delete those domains, old bookmarks and back links will not work.

257,691 | <p>I have a situation where I have to remove a term from a taxonomy. However, there are items that are linked to that taxonomy. Sometimes, these removals are temporary (ie, we stop shipping to a country, but would like items to stay linked to those countries if ever we start shipping to that country again). </p>
<p>Is there any way to 'disable' a term rather than wp_delete_term? Thanks! </p>

| I have a situation where I have to remove a term from a taxonomy. However, there are items that are linked to that taxonomy. Sometimes, these removals are temporary (ie, we stop shipping to a country, but would like items to stay linked to those countries if ever we start shipping to that country again).
Is there any way to 'disable' a term rather than wp\_delete\_term? Thanks! | Not directly, but I have a need for this functionality as well, as part of a plugin I'm writing for a client and have what I think is a pretty good start on an implementation.
The approach I'm taking is to store a term meta when the term is disabled and then to hook into the `get_terms_defaults` filter to strip disabled terms that would be returned by WP Core's calls to `get_terms()`, `get_the_terms()`, etc.
My plugin encapsulates all of this into a class which serves as a wrapper around `register_taxonomy()`. The following is a stripped down version of that class (for the plugin I'm writing, this wrapper does a lot more with custom taxonomies).
See `Custom_Taxonomy::enable_term()` and `Custom_Taxonmy::disable_term()` for the code that adds/deletes the relevant term meta; and see `Custom_Taxonomy::strip_disabled_terms()` for the code that strips disabled terms.
Hopefully, I've left in all of the relevant code from this class when I stripped out the stuff that doesn't apply to this question :-)

My use case
===========
I've got 2 custom post types, `type_a` and `type_b`. `type_b` has a custom taxonomy, `taxonomy_b`, the terms of which are the post\_title's of all of the posts of type `type_a`.
Only those posts of `type_a` whose `post_status` is `publish` should have their corresponding terms in `taxonomy_b` enabled. I accomplish this by hooking into `save_post_type_a` to insert the terms (if they don't already exist) and enable/disable them, and hook into `delete_post` to delete them.
If your use case for disabled terms is at all similar, them the above should at least point you in one possible direction.
Questions I still have
======================
I'm still working on this plugin and there are a few open issues around it's implementation.
1. is the `get_terms_defaults` filter that I hook into to add the meta\_query to `WP_Term_Query` the best hook to use? I've tried `get_terms_args`, but that seems to be called too late in the process of builing the WP\_Term\_Query used by get\_terms(), etc. to correctly process the meta\_query that is added by `Custom_taxonomy::strip_disabled_terms()`.
2. I'm not sure how this interacts with WP Core's object caching. For example, if a term is disabled when a call to `get_terms()` caches the terms in the taxonomy, and them the term is enabled in the same execution of `wp()` will a subsequent call to `get_terms()` include the term or will it return the cached terms...which wouldn't include the term. But it seems to be working in the tests I've done thus far.
If anyone reading this has any suggestions for improvements on this class, especially about the object caching aspect, please, chime in! |

I've got 2 custom post types, `type_a` and `type_b`. `type_b` has a custom taxonomy, `taxonomy_b`, the terms of which are the post\_title's of all of the posts of type `type_a`.
Only those posts of `type_a` whose `post_status` is `publish` should have their corresponding terms in `taxonomy_b` enabled. I accomplish this by hooking into `save_post_type_a` to insert the terms (if they don't already exist) and enable/disable them, and hook into `delete_post` to delete them.
If your use case for disabled terms is at all similar, them the above should at least point you in one possible direction.
Questions I still have
======================
I'm still working on this plugin and there are a few open issues around it's implementation.
1. is the `get_terms_defaults` filter that I hook into to add the meta\_query to `WP_Term_Query` the best hook to use? I've tried `get_terms_args`, but that seems to be called too late in the process of builing the WP\_Term\_Query used by get\_terms(), etc. to correctly process the meta\_query that is added by `Custom_taxonomy::strip_disabled_terms()`.
2. I'm not sure how this interacts with WP Core's object caching. For example, if a term is disabled when a call to `get_terms()` caches the terms in the taxonomy, and them the term is enabled in the same execution of `wp()` will a subsequent call to `get_terms()` include the term or will it return the cached terms...which wouldn't include the term. But it seems to be working in the tests I've done thus far.
If anyone reading this has any suggestions for improvements on this class, especially about the object caching aspect, please, chime in! |
257,702 | <p>I want my <code>single.php</code> to display posts in the same category for the previous and next posts underneath the post. The problem is that each of my posts belongs to multiple categories, and they are displayed through one of the other categories (24) versus the one I want them to display from (27). Does that even make sense?</p>
<p>Example Categories:</p>
<p>Characters (parent category) (Subcategory IDs listed below:)</p>
<ul>
<li>24 (This category ID displaying instead.)</li>
<li>27 (This is the category ID that I want to display.)</li>
</ul>
<p>Now, my question is, how do I choose the category I want to be pulled from (27) instead of the one being automatically pulled (24)? Here is my code below (that I've found and been fiddling with), with what I've tried so far.</p>
<pre><code> <?php
if (is_single() && in_category('stories')) {
$post_id = $post->ID;
$cat = get_the_category(); //I've tried changing this to my category (both ID and slug)
$current_cat_id = $cat[0]->cat_ID; //Also tried plugging ID and slug
$args = array(
'category' => $current_cat_id, //Also tried plugging ID and slug
'orderby' => 'post_date',
'order' => 'DESC'
);
$posts = get_posts($args);
$ids = array();

``` | Not directly, but I have a need for this functionality as well, as part of a plugin I'm writing for a client and have what I think is a pretty good start on an implementation.
The approach I'm taking is to store a term meta when the term is disabled and then to hook into the `get_terms_defaults` filter to strip disabled terms that would be returned by WP Core's calls to `get_terms()`, `get_the_terms()`, etc.
My plugin encapsulates all of this into a class which serves as a wrapper around `register_taxonomy()`. The following is a stripped down version of that class (for the plugin I'm writing, this wrapper does a lot more with custom taxonomies).
See `Custom_Taxonomy::enable_term()` and `Custom_Taxonmy::disable_term()` for the code that adds/deletes the relevant term meta; and see `Custom_Taxonomy::strip_disabled_terms()` for the code that strips disabled terms.
Hopefully, I've left in all of the relevant code from this class when I stripped out the stuff that doesn't apply to this question :-)

I'm not sure from an SEO perspective if leaving the urls ugly would matter. It would be tedious, but if you have `ssh` access, you can use [wp-cli](http://wp-cli.org/) to search and replace the urls in the database:
```
wp search-replace 'example.com?p=123' 'example.com/post-slug'
```
You could also create a bash script to do that for each url.
>

The links will not be broken. From a technical standpoint, WordPress performs a [`302` redirect](https://en.wikipedia.org/wiki/HTTP_302).
So yes, the site will still 'work', but you indicate that this is in conjunction with an SEO initiative.
SEO things have more to do with the various indexes that search engines (Google, Bing, etc) have of your site. Note that a `302` redirect implies that the link has "Moved Temporarily". Since you want to move all of the existing SEO "juice" from the old url to the new url, you need to tell the search engines that "This content exists, and has *permanently* moved". For this you want to use a [`301` redirect](https://en.wikipedia.org/wiki/HTTP_301).
There are a couple of ways to do this.
WordPress Plugins
-----------------
There are a few redirection plugins out there that I like:
* [Safe Redirection
Manager](https://wordpress.org/plugins/safe-redirect-manager/)
* [Simple 301
Redirects](https://wordpress.org/plugins/simple-301-redirects/)
But feel free to search and explore. The main drawback is that you have so many urls to input, and doing so for each url will probably be tedious.
Redirects at the Server Level
-----------------------------
You can also create `301` redirects at the server level.
If you are running apache, then you can use its [mod\_rewrite](https://httpd.apache.org/docs/2.4/rewrite/remapping.html) engine inside of an `.htaccess` file.
Nginx has it's own [rewrite module](http://nginx.org/en/docs/http/ngx_http_rewrite_module.html). I think that this [blog post](https://www.nginx.com/blog/creating-nginx-rewrite-rules/) is a little easier to digest than the docs.
Getting a List of the URLs
--------------------------
In any case, one of the challenges is usually getting a complete list of posts, their ids, and the associated slug.
Since the current permalink structure includes the post ID, and the new permalink structure contains the post slug, getting a list of 'before and after' is pretty easy using `wp-cli`. I've used this before to generate the post list:
```
wp post list --fields=ID,post_name --format=csv > posts.csv
```
This will give us a file called `posts.csv` filled with the post id and slug of all the posts:
```
488,a-new-post-slug
495,another-new-post-slug
504,so-many-post-slugs
# ...
```
From there you can do batch transforms using Vim, Sed, or even a spreadsheet program since it's a csv.
Hope this helps with your planing and execution! |
257,757 | <p>I'm creating an advertising portal for a small network using a custom post type. In order to prevent WordPress database corruption or unauthorized access to user information, I need to keep data separated from the advertising app by duplicating custom post type data to an external database when creating and updating an ad post. I'm using the <code>save_post</code> hook to handle when the function should run, and <code>wp_insert_post()</code> to push all post data into the database.

| I'm creating an advertising portal for a small network using a custom post type. In order to prevent WordPress database corruption or unauthorized access to user information, I need to keep data separated from the advertising app by duplicating custom post type data to an external database when creating and updating an ad post. I'm using the `save_post` hook to handle when the function should run, and `wp_insert_post()` to push all post data into the database. What I want to happen is that the post will save in the WordPress database by default, and also save to an external database using my plugin function.
The issue I can't figure out is how to tell `wp_insert_post()` to use the external database instead of the `global $wpdb` variable it uses by default, as outlined in WP code reference.
How can I use a custom database with `wp_insert_post`? Or is there a better method?
My function, based on WordPress codex and Stack Exchange examples:
```
// Function to push data on update
function my_data_push ($post_id) {
// Check for custom post type
if (get_post_type($post_id) == 'ads'):
// Set up database connection to external ads storage database
$push_to_db = new wpdb('username','password','database','host');
// Insert post data in external database
wp_insert_post($post_id, $wp_error = true);
endif;
}
// Add function to post save hook
add_action('save_post', 'my_data_push');
``` | I have been searching for an answer to this question for over a month now - i do not think wordpress is very good for any site that has a secure external DB or for anyone who does not want to store customer data in the main wordpress database, which is strange as that seems like a highly valued function.
At any rate i came across this code during my research that may help you - it is a global variable for a external DB... according to the author it is usable in the same way as $wpdb global variable is used.
If you want the author's full blurb on it go here <https://bavotasan.com/2011/access-another-database-in-wordpress/>
The code is:
$newdb = new wpdb($DB\_USER, $DB\_PASSWORD, $DB\_NAME, $DB\_HOST);
$newdb->show\_errors();

[](https://i.stack.imgur.com/Nz8Jx.jpg) | 1: You can use [`Page template`](https://developer.wordpress.org/themes/template-files-section/page-templates/) and custom [`WP_Query`](https://codex.wordpress.org/Class_Reference/WP_Query) to show posts from a specific category into a page.
2: you can also achive same thing with [`shortcode`](https://codex.wordpress.org/Shortcode_API) where you will have to create a `shortcode` containing posts from specific category and paste that shortcode into your page.
**Update**
added sample code for custom page template and wp\_query
```
<?php
/**
*
* Template Name: Custom post page
*
**/
get_header(); ?>
<div class="main-content" id="main">
<?php
$args = array(
'post_type' => 'post',
'posts_per_page' => 10,
'category_name' => 'your-category-slug', // replace it with your category slug
);
$query = new WP_Query( $args );
if ( $query->have_posts() ) : ?>
<table class="table post-table">
<thead>
<tr>
<td><strong>Title</strong></td>

As you can see in the image, in each space a blank paragraph is created
[](https://i.stack.imgur.com/RZXjV.png)
And in the\_excerpt too
[](https://i.stack.imgur.com/r6008.png)
[My site](http://gamersaction.com/) if you want to see more examples
Edit:
The answers of [Wordpress tinymce prints empty P tag and break html format](https://wordpress.stackexchange.com/questions/189692/wordpress-tinymce-prints-empty-p-tag-and-break-html-format/190036#190036) did not resolve mine
The paragraphs remain blank and   keeps appearing | Judging from your site's content and the comments, you may try using the following CODE in your theme's `functions.php` file. It'll remove empty `<p> </p>` tags from post content:
```
add_filter( 'the_content', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
add_filter( 'the_excerpt', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
function wpse_257854_remove_empty_p( $content ) {
return str_ireplace( '<p> </p>', '', $content );
}
```
However, after it removes the empty `<p> </p>` tags, paragraphs in your site's post content will collapse with each other. To maintain the visual gap between paragraphs, you may use the following CSS:
```
.conteudo-noticia p {
padding-bottom: 15px;
}
```
If `nbsp;` within meta description tags are coming from content (or excerpt) & the plugin used to capture them are handling the content as it should (according to WordPress loop standard), then after using the above CODE, meta tags should be fixed as well.
>
> ***Note:*** After making the above changes, please make sure you **clear browser cache** properly and clear any server cache (from cache plugin, web server etc.) if present before testing the result.
>
>
>
Update:
=======
If you don't want to control paragraph gap with CSS padding, then there is a slightly different CODE you may try:
```
add_filter( 'the_content', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
add_filter( 'the_excerpt', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
function wpse_257854_remove_empty_p( $content ) {
return str_ireplace( '<p> </p>', '<br>', $content );
}
```
This CODE, instead of removing the empty `p` tags, replaces them with line breaks `<br>`. So this way you can control paragraph gaps from within the editor without having empty `p` tags with ` `. |

| I've created a new widget based on one of my parent theme's custom widgets. In the parent theme the widget files are in the `/inc` and `template-parts` folders. I created these same folders in my child theme but can't get the widget to show up on the widgets page. However, it works if I add the widget code to the `functions.php` file.
**UPDATE:**
Now I have another problem: `Fatal error: Call to undefined function add_action()`
This is the code I'm using to register the widget:
```
// Register the widget
function myplugin_register_widgets() {
register_widget( 'Home_Categories' );
}
add_action( 'widgets_init', 'myplugin_register_widgets' );
```
This is how the original widget is registered:
```
// Register the widget
add_action( 'widgets_init', create_function( '', 'return register_widget("Codilight_Widget_Block1");'));
``` | Judging from your site's content and the comments, you may try using the following CODE in your theme's `functions.php` file. It'll remove empty `<p> </p>` tags from post content:
```
add_filter( 'the_content', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
add_filter( 'the_excerpt', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
function wpse_257854_remove_empty_p( $content ) {
return str_ireplace( '<p> </p>', '', $content );
}
```
However, after it removes the empty `<p> </p>` tags, paragraphs in your site's post content will collapse with each other. To maintain the visual gap between paragraphs, you may use the following CSS:
```
.conteudo-noticia p {
padding-bottom: 15px;
}
```
If `nbsp;` within meta description tags are coming from content (or excerpt) & the plugin used to capture them are handling the content as it should (according to WordPress loop standard), then after using the above CODE, meta tags should be fixed as well.
>
> ***Note:*** After making the above changes, please make sure you **clear browser cache** properly and clear any server cache (from cache plugin, web server etc.) if present before testing the result.

Update:
=======
If you don't want to control paragraph gap with CSS padding, then there is a slightly different CODE you may try:
```
add_filter( 'the_content', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
add_filter( 'the_excerpt', 'wpse_257854_remove_empty_p', PHP_INT_MAX );
function wpse_257854_remove_empty_p( $content ) {
return str_ireplace( '<p> </p>', '<br>', $content );
}
```
This CODE, instead of removing the empty `p` tags, replaces them with line breaks `<br>`. So this way you can control paragraph gaps from within the editor without having empty `p` tags with ` `. |

(and I have tried various combos with and without page name, and using `page` or `pagename` in place of `name`, all with no luck) | OK, let's first get some definitive clarification on the proper query vars.
Refer to [Post and Page parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Post_.26_Page_Parameters) on the `WP_Query` codex page.
>
> name (string) - use post slug.
>
>

We can confirm this with `WP_Query`:
```
$args = array(
'name' => 'mypage'
);
$mypage = new WP_Query( $args );
echo '<pre>';
print_r( $mypage );
echo '</pre>';
```
which will produce:
```
SELECT wp_posts.*
FROM wp_posts
WHERE 1=1
AND wp_posts.post_name = 'mypage'
AND wp_posts.post_type = 'post'
ORDER BY wp_posts.post_date DESC
```
It's looking for `mypage` slug in the `post` post type. If we change this to `pagename`, it looks in the `page` post type.
The reason it *kind of* works on the main query with `name` is due to the [`redirect_guess_404_permalink`](https://codex.wordpress.org/Function_Reference/redirect_guess_404_permalink) function, which kicks in when the original request is a 404. It runs another query to find the closest match and redirect there, if something is found. This also results in any extra parameters getting stripped from the URL.
One important thing to note with hierarchical post types- if your page is a child of another page, you must set the `pagename` query var with the `parent/child` path, as different parents can have children with the same slug.
As for your question, changing the query var to `pagename` works with your original code in v4.7.2 and the Twenty Sixteen theme:
```
function wpd_mypage_rewrite() {
add_rewrite_tag(
'%mycustomvar%',
'([^/]+)'
);
add_rewrite_rule(
'^mypage/([^/]+)/?',
'index.php?pagename=mypage&mycustomvar=$matches[1]',
'top'
);
}
add_action( 'init', 'wpd_mypage_rewrite' );
```
Note that I used `add_rewrite_tag` here. You could *instead* use the [`query_vars` filter](https://codex.wordpress.org/Plugin_API/Filter_Reference/query_vars). The reason `add_rewrite_tag` works is that it internally adds the query var via the same filter.
Don't forget to [flush rewrite rules](https://codex.wordpress.org/Function_Reference/flush_rewrite_rules) after adding / changing rules. You can also do this by visiting the Settings > Permalinks page.
You can then `echo get_query_var( 'mycustomvar' );` in the template, and the value is output. |

I had something in mind like this:
```
<textarea =id"textarea">
function answerbutton() {
document.getElementById("answer").innerHTML = 'ID="textarea"';
}
```
But I cannot get it to work.. my javascript skill is zero.
Could someone help me to the right way?
Or give me 'hints'?
Is there a WordPress plugin that can do this for example?
This is what I added to the loop? I guess the index.php:
```
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<p><?php the_content(__('(more...)'));
$hint1_of_this_page = get_post_meta( get_the_ID(), 'hint1', true );
$hint2_of_this_page = get_post_meta( get_the_ID(), 'hint2', true );
$hint3_of_this_page = get_post_meta( get_the_ID(), 'hint3', true );
$hint4_of_this_page = get_post_meta( get_the_ID(), 'hint4', true );
$answerbutton_of_this_page = get_post_meta( get_the_ID(), 'answerbutton', true );
$correctanswervalidate = get_post_meta( get_the_ID(), 'correctanswervalidate', true );
?></p>
<hr> <?php endwhile; else: ?>
```
Thhis is what I added to the footer.php:
```
<script type="text/javascript">
function answerbutton() {
document.getElementById("answer").innerHTML = '<?php echo $answerbutton_of_this_page; ?>';
}
</script>
<script type="text/javascript">
function hintbutton() {
document.getElementById("hint1").innerHTML = '<?php echo $hint1_of_this_page; ?>';
}
</script>
<script type="text/javascript">
function hintbutton2() {
document.getElementById("hint2").innerHTML = '<?php echo $hint2_of_this_page; ?>';
}
</script>
```
and this is how I use the custom field:
[](https://i.stack.imgur.com/sIhHP.png) | OK, let's first get some definitive clarification on the proper query vars.
Refer to [Post and Page parameters](https://codex.wordpress.org/Class_Reference/WP_Query#Post_.26_Page_Parameters) on the `WP_Query` codex page.
>
> name (string) - use post slug.
>
>
> pagename (string) - use page slug.
>
>
>
We can confirm this with `WP_Query`:
```
$args = array(
'name' => 'mypage'
);
$mypage = new WP_Query( $args );
echo '<pre>';
print_r( $mypage );
echo '</pre>';
```
which will produce:
```
SELECT wp_posts.*
FROM wp_posts
WHERE 1=1
AND wp_posts.post_name = 'mypage'
AND wp_posts.post_type = 'post'
ORDER BY wp_posts.post_date DESC
```
It's looking for `mypage` slug in the `post` post type. If we change this to `pagename`, it looks in the `page` post type.
The reason it *kind of* works on the main query with `name` is due to the [`redirect_guess_404_permalink`](https://codex.wordpress.org/Function_Reference/redirect_guess_404_permalink) function, which kicks in when the original request is a 404. It runs another query to find the closest match and redirect there, if something is found. This also results in any extra parameters getting stripped from the URL.
One important thing to note with hierarchical post types- if your page is a child of another page, you must set the `pagename` query var with the `parent/child` path, as different parents can have children with the same slug.
As for your question, changing the query var to `pagename` works with your original code in v4.7.2 and the Twenty Sixteen theme:
```
function wpd_mypage_rewrite() {
add_rewrite_tag(
'%mycustomvar%',
'([^/]+)'
);
add_rewrite_rule(
'^mypage/([^/]+)/?',
'index.php?pagename=mypage&mycustomvar=$matches[1]',
'top'
);
}
add_action( 'init', 'wpd_mypage_rewrite' );
```
Note that I used `add_rewrite_tag` here. You could *instead* use the [`query_vars` filter](https://codex.wordpress.org/Plugin_API/Filter_Reference/query_vars). The reason `add_rewrite_tag` works is that it internally adds the query var via the same filter.
Don't forget to [flush rewrite rules](https://codex.wordpress.org/Function_Reference/flush_rewrite_rules) after adding / changing rules. You can also do this by visiting the Settings > Permalinks page.
You can then `echo get_query_var( 'mycustomvar' );` in the template, and the value is output. |

| I am trying to build a plugin that will replace one file from the theme. It will be plugin for certain theme that has a file placed in includes folder to the path would be:
wp-content/theme/includes/example-file.php
This example-file.php is loaded in header and footer also via `include`
I want to make a plugin that would overwrite example-file.php so that theme includes that file from my plugin and not the includes folder from theme.
How is that possible, what would be the best way to do this? | WordPress way (recommended):
============================
In your plugin, use the WordPress `theme_file_path` filter hook to change the file from the plugin. Use the following CODE in your plugin:
```
add_filter( 'theme_file_path', 'wpse_258026_modify_theme_include_file', 20, 2 );
function wpse_258026_modify_theme_include_file( $path, $file = '' ) {
if( 'includes/example-file.php' === $file ) {
// change path here as required
return plugin_dir_path( __FILE__ ) . 'includes/example-file.php';
}
return $path;
}
```
Then you may include the file in your theme using the [`get_theme_file_path`](https://developer.wordpress.org/reference/functions/get_theme_file_path/) function, like this:
```
include get_theme_file_path( 'includes/example-file.php' );
```
Here, if the file is matched in the plugin's filter hook, then the plugin version of the file will be included, otherwise the theme version will be included.
Also, this way, even if the plugin is disabled, the theme will work with its own version of the file without any modification.
Controlling Page Template from Plugin:
======================================
If you are looking for controlling page templates from your plugin, then you may [check out this answer](https://wordpress.stackexchange.com/a/257674/110572) to see how to do it.
PHP way:
========
If you are including the `wp-content/theme/<your-theme>/includes/example-file.php` file using simple `include` call with **relative path** inside header, footer templates like the following:
```
include 'includes/example-file.php';
```
then it's also possible to replace it with the plugin's version of `includes/example-file.php` file using PHP `set_include_path()` function.
Generally speaking, to include a file with relative path, PHP looks for the file in the current directory. However, you can manipulate it so that PHP looks for it in another path first. In that case, use the following PHP CODE in your plugin's main PHP file to include the plugin's directory into PHP's default include path:
```
set_include_path( plugin_dir_path( __FILE__ ) . PATH_SEPARATOR . get_include_path() );
```
After that, for any `include` with relative path in `header.php`, `footer.php` etc. PHP will look for the file in your plugin's directory first.

| I am working with twenty fourteen theme.
I want to customize the full-width template for my needs, to make it wider on specific pages.
so I copied it into a sub folder in my child theme.
how do I embed styling that will affect this template ONLY?
tried this, but it doesnt work: <http://www.transformationpowertools.com/wordpress/real-full-width-page-template-twentyfourteen>
p.s: I am not a developer :( | WordPress way (recommended):
============================
In your plugin, use the WordPress `theme_file_path` filter hook to change the file from the plugin. Use the following CODE in your plugin:
```
add_filter( 'theme_file_path', 'wpse_258026_modify_theme_include_file', 20, 2 );
function wpse_258026_modify_theme_include_file( $path, $file = '' ) {
if( 'includes/example-file.php' === $file ) {
// change path here as required
return plugin_dir_path( __FILE__ ) . 'includes/example-file.php';
}
return $path;
}
```
Then you may include the file in your theme using the [`get_theme_file_path`](https://developer.wordpress.org/reference/functions/get_theme_file_path/) function, like this:
```
include get_theme_file_path( 'includes/example-file.php' );
```
Here, if the file is matched in the plugin's filter hook, then the plugin version of the file will be included, otherwise the theme version will be included.
Also, this way, even if the plugin is disabled, the theme will work with its own version of the file without any modification.
Controlling Page Template from Plugin:
======================================
If you are looking for controlling page templates from your plugin, then you may [check out this answer](https://wordpress.stackexchange.com/a/257674/110572) to see how to do it.
PHP way:
========
If you are including the `wp-content/theme/<your-theme>/includes/example-file.php` file using simple `include` call with **relative path** inside header, footer templates like the following:
```
include 'includes/example-file.php';
```
then it's also possible to replace it with the plugin's version of `includes/example-file.php` file using PHP `set_include_path()` function.
Generally speaking, to include a file with relative path, PHP looks for the file in the current directory. However, you can manipulate it so that PHP looks for it in another path first. In that case, use the following PHP CODE in your plugin's main PHP file to include the plugin's directory into PHP's default include path:
```
set_include_path( plugin_dir_path( __FILE__ ) . PATH_SEPARATOR . get_include_path() );
```
After that, for any `include` with relative path in `header.php`, `footer.php` etc. PHP will look for the file in your plugin's directory first.
