320,377 | <p>I want to run my own JavaScript on a specific WordPress page but only after a third party's plugin runs as I am trying to slightly modify that plugin.

320,448 | <p>I am wondering if the below logic is correct and if certain circumstances should be present for it to work, since in some cases it does not seem to be working. </p>
<p>The example below is quite simple. Let's say that I want to use a function, that is defined elsewhere in a theme-related file, let's say <code>parent_theme_hooks.php</code>, through an action hook in my child-theme <code>functions.php</code>.</p>
<p><strong>parent_theme_hooks.php</strong></p>
<pre><code>function is_enabled(){
return true;
}
function check_if_enabled(){
do_action( 'my_hook', $some, $args );
}
</code></pre>
<p>Then in the child-theme <strong>functions.php</strong></p>
<pre><code>function my_function($some, $args) {
if ( is_enabled() ) {
$message = 'yes';
} else {
$message = 'no';
}
echo $message;
}
add_action( 'my_hook', 'my_function', 11, 2 );
</code></pre>
<p><strong>Question</strong>
So my question is if I can use the function <code>is_enabled()</code> in the child-theme <code>functions.php</code> when it is defined elsewhere in the parent theme?</p>
<p>Thanks</p>

if (( in_category('Locked') ) && in_array( 'subscriber', (array) $user->roles ) ) && ?????
```
If this way can't work, I would have one more possible solution, it is to auto move user from subscriber to contributor once subscriber posted number of posts, but this first solution would be better. | I guess [`count_user_posts`](https://codex.wordpress.org/Function_Reference/count_user_posts) is what you're looking for ;)
This is how you use it:
```
$user_post_count = count_user_posts( $userid , $post_type );
```
And it returns the number of published posts the user has written in this post type.
PS. And if you want some more advanced count, [`get_posts_by_author_sql`](https://codex.wordpress.org/Function_Reference/get_posts_by_author_sql) can come quite handy. |

320,599 | <p>I want to sort posts by a meta value in a custom field. Basically I've added a field called 'date_event' and want to sort the posts by that date (stored as YYYYMMMDD).</p>
<p>The only working example I have is this placed in the loop.php:</p>
<pre><code>$query = new WP_Query(
array(
'meta_key' => 'date_event',
'orderby' => 'meta_value_num',
'order' => 'DESC',
)
);
</code></pre>
<p>This does the trick by sorting, but it takes all posts and sorts them no matter what category I'm viewing. From what I can see it's because I've called the <code>$query</code> again and not 'filtering' the posts I guess. It might also just be bad coding. </p>
<p>Anyway my goal is to have the posts sorted but only display the posts that are in that category you are in.</p>
<p>Any tips or references are greatly appreciated.</p>

"text": "<p>Creating a Multilingual WordPress Site (Human Translation)\nFirst thing you need to do is install and activate the Polylang plugin. Upon activation, you need to visit Settings » Languages to configure the plugin.</p>\n\n<p>Polylang settings page</p>\n\n<p>The language settings page is divided into three tabs. The first tab is labeled ‘Languages’. This is where you add the languages you want to use on your site.</p>\n\n<p>You will need to add the default language, as well as select all other languages that users can choose on your site.</p>\n\n<p>After adding the languages, switch to the ‘Strings Translations’ tab. Here you need to translate site title, description, and then choose the date and time format.</p>\n\n<p>Translating strings</p>\n\n<p>Last step in the configuration is the Settings tab. This is where you can choose a default language for your site and other technical settings.</p>\n\n<p>Setting up a URL structure</p>\n\n<p>For most beginners, we recommend not changing the URL, so select the first option. Why? Because if you ever turn off this plugin, then all those links will be broken.</p>\n\n<p>For those who are looking to take full advantage of multi language SEO, then we recommend that you choose the second option for pretty permalinks as shown in the screenshot above.</p>\n\n<p>You should select the option for detecting browser’s preferred language, and automatically show them the content in their preferred language. By doing this, the user will see the content in their preferred language and can switch the language if needed.</p>\n\n<p>Once you are done, click on the save changes button to store your settings.</p>\n\n<p>Adding Multilingual Content in WordPress\nPolylang makes it super easy to add content in different languages. Simply create a new post/page or edit an existing one. On the post edit screen, you will notice the languages meta box.</p>\n\n<p>Adding Multi-Lingual Content in WordPress using Polylang plugin</p>\n\n<p>Your default language will automatically be selected, so you can first add content in your default language, and then translate it into others.</p>\n\n<p>To translate, you need to click on the + button next to a language and then add content for that language.</p>\n\n<p>A multi-lingual blog post in WordPress created with Polylang</p>\n\n<p>Repeat the process for all languages. Once you are done, you can publish your posts and pages.</p>\n\n<p>It’s important to note that Polylang works with custom post types, so it can definitely help you make your woocommerce store multilingual.</p>\n\n<p>Translating Categories, Tags, and Custom Taxonomies\nYou can also translate categories and tags, or any custom taxonomies you may be using.</p>\n\n<p>If you want to translate categories, then go to Posts » Categories.</p>\n\n<p>Translating categories</p>\n\n<p>Add a category in your default language and then click on the plus icon for each language to start adding translations.</p>\n\n<p>Displaying Multi Language Switcher on Your WordPress Site\nAdding a language switcher allows users to select a language when viewing your site. Polylang makes it super simple. Just go to Appearance » Widgets and add the language switcher widget to your sidebar or another widget-ready area.</p>\n\n<p>Language switcher</p>\n\n<p>You can choose a drop down, or use language names with flags. Once you are done, click the save button to store your widget settings.</p>\n\n<p>You can now preview your site to see the language switcher in action.</p>\n\n<p>Language switcher on a live WordPress site</p>\n\n<p>Using Google Translate to Create a Multilingual Site in WordPress\nWhile adding human translations definitely creates a better user experience, you may not have the resources or time to do that. In that case, you can try using Google Translate to automatically translate content on your site.</p>\n\n<p>First thing you need to do is install and activate the Google Language Translator plugin. Upon activation, visit Settings » Google Language Translator to configure the plugin.</p>\n\n<p>Google Language Translator plugin</p>\n\n<p>The plugin allows you to select the languages available with Google Translate. You can even remove Google’s branding from translation. This is a highly customizable plugin, so you need to go through the settings and configure it to your liking.</p>\n\n<p>For more details check out our tutorial on how to add Google Translate in WordPress with video and text instructions on how to set up the plugin.</p>\n\n<p>That’s all, we hope this article helped you learn how to create a multilingual site in WordPress. You should also look at our article on how to install WordPress in your language.</p>\n\n<p>If you are looking for a multilingual WordPress theme also referred to translation-ready themes, check out our guide on how to find translation ready WordPress themes that also has an easy way to translate existing WordPress themes.</p>\n"

| I want to sort posts by a meta value in a custom field. Basically I've added a field called 'date\_event' and want to sort the posts by that date (stored as YYYYMMMDD).
The only working example I have is this placed in the loop.php:
```
$query = new WP_Query(
array(
'meta_key' => 'date_event',
'orderby' => 'meta_value_num',
'order' => 'DESC',
)
);
```
This does the trick by sorting, but it takes all posts and sorts them no matter what category I'm viewing. From what I can see it's because I've called the `$query` again and not 'filtering' the posts I guess. It might also just be bad coding.
Anyway my goal is to have the posts sorted but only display the posts that are in that category you are in.
Any tips or references are greatly appreciated. | I have used [Polyang](https://wordpress.org/plugins/polylang/) in the past which works nicely for manual translations. Here is a [guide](https://www.wpbeginner.com/beginners-guide/how-to-easily-create-a-multilingual-wordpress-site/) that covers it. |

Check it now, with 4.9 and current version of WordPress, and all possible combinations of Classic Editor and Gutenberg/Block Editor. I will be happy to discuss tested solution, not links to something. | There are several variants:

* WordPress 5.0, Classic Editor plugin is active, but in site console in “Settings > Writing” the option “Use the Block editor by default…” is selected
All the mentioned variants can be processed by the following code:
```

| I set cookie for my users to know from which source they come to the site and I want when user contact us their message comes with their cookie as well.
So that I created a new shortcode and added in mail section but it mails direct shortcode not its returned value

```
add_action( 'wpcf7_init', 'custom_add_form_tag_my_source' );
function custom_add_form_tag_my_source() {
// "my-source" is the type of the form-tag
wpcf7_add_form_tag( 'my-source', 'custom_my_source_form_tag_handler' );
}
function custom_my_source_form_tag_handler( $tag ) {

}
```
See the [documentation](https://contactform7.com/2015/01/10/adding-a-custom-form-tag/) for more details.

$components['body'] = do_shortcode( $components['body'] );
return $components;
} );

320,884 | <p>I'm trying to change the text in the 'Place order' button on my multilingual site in WooCommerce. My default lang is English US, other is Polish. I can easily modify the secondary language text via my WPML plugin, but I cannot change the default language.
I tried modifying the button text via a JS code which worked in the default EN page, but the Polish one started to display the new English text too. I also tried using Loco and adding English as a language, changed the English text - but that didn't work. How is this doable - to change text strings in default language and making them translatable via WPML in the same time?</p>

```
function unset_filter_session() {
if ( ! wp_doing_ajax() ) {
//Reset sessions on refresh page
unset( $_SESSION['expenditure_filter'] );
}
}
```
UPDATE
------
*You can check the answer's revision for this update part..*
UPDATE #2
---------
Sorry, I didn't realize that you're loading a page fragment (`#content-area`) using the [`jQuery.load()`](http://api.jquery.com/load/) method. Or that you're not using the `admin-ajax.php` to handle the AJAX request.
So if you're *not* using the [`wp_ajax_{action}`](https://developer.wordpress.org/reference/hooks/wp_ajax__requestaction/) or [`wp_ajax_nopriv_{action}`](https://developer.wordpress.org/reference/hooks/wp_ajax_nopriv__requestaction/) action, or with the way you do the AJAX request, you can check whether the `X-Requested-With` header is set and that its value is `XMLHttpRequest`, and if so, you can cancel the session unsetting, like so:
```
function unset_filter_session() {
if ( empty( $_SERVER['HTTP_X_REQUESTED_WITH'] ) ||
'XMLHttpRequest' !== $_SERVER['HTTP_X_REQUESTED_WITH'] ) {
//Reset sessions on refresh page, if not doing AJAX request
unset( $_SESSION['expenditure_filter'] );
}
}
```
That should work because jQuery always sets that header, unless you explicitly remove it — or change its value.
See the `headers` option on the `jQuery.ajax()` [reference](http://api.jquery.com/jquery.ajax/):
>
> The header `X-Requested-With: XMLHttpRequest` is always added, but its
> default `XMLHttpRequest` value can be changed
>
>
>
**Note: The header name is `X-Requested-With`, but in the superglobal `$_SERVER`, its key is `HTTP_X_REQUESTED_WITH`. I.e. *Don't* use `$_SERVER['X-Requested-With']`.**
UPDATE #3
---------
As suggested by [Lawrence Johnson](https://wordpress.stackexchange.com/users/22714/lawrence-johnson), you (ahem, we) should use [`filter_input()`](http://php.net/manual/en/function.filter-input.php):
```
function unset_filter_session() {
if ( 'XMLHttpRequest' !== filter_input( INPUT_SERVER, 'HTTP_X_REQUESTED_WITH' ) ) {
//Reset sessions on refresh page, if not doing AJAX request
unset( $_SESSION['expenditure_filter'] );
}
}

| As the 5.0 is getting real, and so is Gutenberg...
Is it possible to disable Gutenberg and use previous TinyMCE editor?
How to do this? | Yes, you can disable it.
You can do this with code
-------------------------
If you want to disable it globally, you can use this code:
```
if ( version_compare($GLOBALS['wp_version'], '5.0-beta', '>') ) {
// WP > 5 beta
add_filter( 'use_block_editor_for_post_type', '__return_false', 100 );
} else {
// WP < 5 beta
add_filter( 'gutenberg_can_edit_post_type', '__return_false' );
}
```
And if you want to disable it only for given post type, you can use:
```
function my_disable_gutenberg_for_post_type( $is_enabled, $post_type ) {
if ( 'page' == $post_type ) { // disable for pages, change 'page' to you CPT slug
return false;
}
return $is_enabled;
}
if ( version_compare($GLOBALS['wp_version'], '5.0-beta', '>') ) {
// WP > 5 beta
add_filter( 'use_block_editor_for_post_type', 'my_disable_gutenberg_for_post_type', 10, 2 );
} else {
// WP < 5 beta
add_filter( 'gutenberg_can_edit_post_type', 'my_disable_gutenberg_for_post_type', 10, 2 );
}
```
PS. If you don't want to support older versions, you can ignore filters beginning with 'gutenberg\_', so no version checking is needed in such case.
Or using one of existing plugins

---
Additional information about my blog specifically, while the information above is more general/universal.
In my blog I also have a category that is excluded from the blog and only shown on a specific page. How would I exclude this category from the whole solution for the initial question? Would it simply be enough to write `'cat' => -123,`? | So the easiest way to do this would be to store the ID of the first post `(1)` then in each of your category loops you can use the `post__not_in` property like so:
```
// inside the first loop at the top.
$latest_post_id = get_the_ID();
// WP_Query for fetching each category
$category_query = new WP_Query( [
// other parameters
'post__not_in' => [ $latest_post_id ],
] );
```
Now to exclude a category in `WP_Query` you can use `category__not_in` which takes an array of category ID's. It's definitely worth checking out the wordpress codex for [WP\_Query](https://codex.wordpress.org/Class_Reference/WP_Query) |

Any thoughts on what is wrong and is throwing the PHP notice? Any ideas on a better query to get the user ID by first name/last name meta keys? | The value passed to [`reset()`](http://php.net/manual/en/function.reset.php) is [passed by reference](http://php.net/manual/en/language.references.pass.php), which means technically it modifies the original variable that's passed to it. For this to work you need to pass a variable, not a function that returns a value.

All you need to do is assign the returned value if `get_users()` to a variable and then use `reset()` on *that*:
```
$users = get_users( array(
'meta_query' => array(
'relation' => 'AND',
array(
'key'=>'first_name',
'value' => $pieces[0],
'compare' => '='

| Is there a setting in WordPress Gutenberg editor to change the font size of the text we type while writing posts? I mean the text size inside the editor itself, not the published text that blog visitors view. | If you came here, like me, looking for how to adjust the available text size options within Gutenberg, you can add this code to your theme's `functions.php` file (you can add as many options as you like):
```
add_theme_support(
'editor-font-sizes',
array(
array(
'name' => __( 'Normal', 'your-theme-text-domain' ),
'shortName' => __( 'N', 'your-theme-text-domain' ),
'size' => 14,
'slug' => 'normal'
),
array(
'name' => __( 'Medium', 'your-theme-text-domain' ),
'shortName' => __( 'M', 'your-theme-text-domain' ),
'size' => 16,
'slug' => 'medium'
)
)
);
```
This gives the following result within the Gutenberg editor:

You can add `add_theme_support( 'disable-custom-font-sizes' );` to your `functions.php` to remove the numerical input, although the "Custom" option will still be visible in the dropdown. |

They are stored via the keys `upload_path` and `upload_url_path`.
Before:
[](https://i.stack.imgur.com/aVQXH.png)
Run (or add directly in the DB)
```
$ wp option set upload_path foo
$ wp option set upload_url_path bar
```
After:

321,422 | <p>very new here to php and wordpress coding (1 day lol). This is my code so far, the problem is that when there is no value assigned to this attribute I receive and error message. I know I need something that says if the value exists then display the rest of the code but not sure how to go about adding that. This is for a woocommerce product attribute btw.</p>
<p>Code so far:</p>
<pre><code>$collection_values = get_the_terms( $product->id, 'pa_collection');
foreach ($collection_values as $collection_value){
echo '<h2 class="collection_title"><a href="'.get_term_link($collection_value->slug, $collection_value->taxonomy).'">'.$collection_value->name.'</a></h2>';
}
</code></pre>
<p>Error message:</p>
<pre><code>Warning: Invalid argument supplied for foreach() in /app/public/wp-content/themes/savoy/woocommerce/single-product/title.php on line 21
</code></pre>
<p>EDIT： I am adding this above the product title in the title.php page.</p>

Maybe this will be enough for future versions, here's the thorough, cumbersome way that works for older versions, too:
1. check `db_version` at [Codex / Wordpress Versions](https://codex.wordpress.org/Current_events), **or** manually/programmatically:
1. check `wp-includes/version.php` of the version we are updating *from*, [4.9.8](https://github.com/WordPress/WordPress/blob/4.9.8/wp-includes/version.php#L14):
`$wp_db_version = 38590;`
2. repeat for version we are updating *to*; [5.0](https://github.com/WordPress/WordPress/blob/5.0/wp-includes/version.php#L14): `$wp_db_version = 43764;`
2. check `upgrade_all` in `wp-admin/includes/upgrade.php`, for [4.9.8→5.0 / 38590→43764](https://github.com/WordPress/WordPress/blob/5.0/wp-admin/includes/upgrade.php#L642-L643):
```php
// ...
if ( $wp_current_db_version < 37965 ) // false
upgrade_460();
if ( $wp_current_db_version < 43764 ) // true!
upgrade_500();
```
3. finally, inspecting [`upgrade_500`](https://github.com/WordPress/WordPress/blob/5.0/wp-admin/includes/upgrade.php#L1820-L1836), reveals some Gutenberg-juggling and a `FIXME` :)
4. Conclusion: Only very minor database upgrades (one site option is set), so it should be fine, just keep an eye out for Gutenberg & Classic Editor plugin.
UPDATE/EDIT, regarding the "Background": So I did do a manual update 4.9.9→5.0 and then a manual downgrade 5.0→4.9.9 (4.9.8 and .9 don't differ DB-wise). I was presented with the "DB Upgrade required" screen **both** ways, and proceeded. What happens upon downgrade would need more research; my guess is that you only see the screen and none of the `upgrade_*` functions are executed. After up-and-downgrade everything *looks* normal, at least for this minimal, fresh install. So I will feel free to upgrade 4.9.8 to 5.0, knowing I can switch back should anything go wrong. YMMV, of course, especially when other plugins and themes are involved. Wouldn't do it for bigger version jumps, though :) |

| What I'm trying to do is to take the categories for products which are in the cart. Then check via some conditions what category id is and show different notice.
So far I have this
```
/**
* Cart collaterals hook.
*
* @hooked woocommerce_cross_sell_display
* @hooked woocommerce_cart_totals - 10
*/
$categories = array( 39 );
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ) {
$found = true; // Set to true
break; // Stop the loop
}
}
if( $found ) {
echo 'Category with ID = 39';
}
else if ($found != $cart_item['category_ids']) {
echo "Category with ID = 39 and other ID('s)";
}
else {
"Category with ID != 39";
}
```
Seems like `$cart_item['category_ids']` doesn't return categories. `$found` is working and showing category with ID = 39.
When I `var_dump($cart_items)` I do see different categories like this:
```
["category_ids"]=>
array(1) {
[0]=>
int(39)
}
/// another stuff in the array
["category_ids"]=>
array(2) {
[0]=>
int(32)
[1]=>
int(33)
}
```
So, in cart I have products from categories with id `39`, `32` and `33`.
I've tried also `WC()->cart->get_cart()->category_ids` but this return `NULL`
UPDATE: This
```
$cat_ids = array();
foreach ( wc()->cart->get_cart() as $cart_item_key => $cart_item ) {
$cat_ids = array_merge(
$cat_ids, $cart_item['data']->get_category_ids()
);
}
$cat_id = 39;
if ( in_array( $cat_id, $cat_ids ) ) {
echo 'Only 39 ';
} elseif ( ! empty( $cat_ids ) ) {
echo '39 + other';
} else {
echo ' all other without 39';
}
```
Currently matching
When: category 39 + other -> `Only 39`
When: all other without 39 -> `39 + other`
When: Only 39 -> `Only 39`
It should be
When: category 39 + other -> `39 + other`
When: all other without 39 -> `all other without 39`
When: Only 39 -> `Only 39`
**UPDATE**
When: Category 39 + product from other category ( Category ID = 32, 33 etc )
```
var_dump(count( $cat_ids )); -> int(1)
var_dump($has_cat); -> bool(true)
var_dump(cat_ids); -> array(1) { [0]=> int(39) } <---- there are 3 products in the cart 2 of them are from other categories.
```
When: Category 39 only
```
var_dump(count( $cat_ids )); -> int(1)
var_dump($has_cat); -> bool(true)
var_dump(cat_ids); -> array(1) { [0]=> int(39) }
```
When: No category 39
```
var_dump(count( $cat_ids )); -> int(2)
var_dump($has_cat); -> bool(false)
var_dump(cat_ids); -> array(2) { [0]=> int(32) [1]=> int(33) } <--- product is added in 2 categories
```
**UPDATE 2**
Condition 1
```
1) cat 30;
2) cat 39;
$cond = 2 (because there are products in cart from 39 + other category)
```
Condition 2
```
1) cat 39;
$cond = 1 (because in cart is/are product/s only from cat 39)
```
Condition 3
```
1) cat 40;
2) cat 15;
$cond = last one (because there is no product/s from cat 39 in cart)
``` | Use `$cart_item['data']->get_category_ids()` to retrieve the category IDs:
```
$category_ids = $cart_item['data']->get_category_ids(); // array
```
The `category_ids` you see is not a direct item in the `$cart_item` array:
```
var_dump( $cart_item['category_ids'] ); // null and PHP throws a notice
```
It's an item in a *protected* property of the product data (`$cart_item['data']`) which is an object, or a class instance — e.g. the class is `WC_Product_Simple` for Simple products.
UPDATE
------
If you want to collect all the product category IDs, you can do it like so:
```
$cat_ids = array();
foreach ( wc()->cart->get_cart() as $cart_item_key => $cart_item ) {
$cat_ids = array_merge(
$cat_ids, $cart_item['data']->get_category_ids()
);
}
var_dump( $cat_ids );
```
UPDATE #2
---------
You can use this to check if a product in the cart is in certain categories:
```
$cat_ids = array( 39 );
foreach ( wc()->cart->get_cart() as $cart_item_key => $cart_item ) {
if ( has_term( $cat_ids, 'product_cat', $cart_item['data'] ) ) {
echo 'Has category 39<br>';
} else {
echo 'No category 39<br>';
}
}
```
UPDATE #3/#4/#5
---------------
This should work as expected:
```
// Collect the category IDs.
$cat_ids = array();
foreach ( wc()->cart->get_cart() as $cart_item_key => $cart_item ) {
$cat_ids = array_merge(
$cat_ids, $cart_item['data']->get_category_ids()
);
}
// And here we check the IDs.
$cat_id = 39;
$count = count( $cat_ids );
if ( 1 === $count && in_array( $cat_id, $cat_ids ) ) {
echo 'Only in category 39';
} elseif ( $count && in_array( $cat_id, $cat_ids ) ) {
echo 'In category 39 and other categories';
} else {
echo 'No category 39';
}
```
Here's an alternate version of the `if` block above:
```
if ( $count && in_array( $cat_id, $cat_ids ) ) {
// Only one category.
if ( $count < 2 ) {
echo 'Only in category 39';
// Multiple categories.
} else {
echo 'In category 39 and other categories';
}
} else {
echo 'No category 39';
}

| I made a plugin that basically reads a CSV file and imports data to relevant tables.
However, the action seems to create an error:
>
> Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 65015808 bytes) in **/var/www/proj/wp-includes/functions.php** on line
>
>
>
which led me to this code in functions.php:
```
function wp_ob_end_flush_all() {
$levels = ob_get_level();
for ($i=0; $i<$levels; $i++)
ob_end_flush();
}
```
I did a Google and came across two popular solutions, both of which didn't seem to work.
>
> Solution 1: disabling zlib - this is already disabled.
>
> Solution 2: `remove_action('shutdown', 'wp_ob_end_flush_all', 1);`
>
>
>
Solution 2 still errors but with no message, which, isn't exactly ideal.

it's triggered through a button press and uses AJAX to handle it etc.
I'm not sure why a memory leak is occurring or why WordPress doesn't offer more useful error messages. I don't call that function.. so I'm guessing it's something WordPress is doing in the background when things are run.

WordPress running version: 4.9.8 | Depending on what exactly you're trying to achieve, I agree with [Tom's comment](https://wordpress.stackexchange.com/questions/321657/memory-leak-in-plugin-action?noredirect=1#comment475327_321657), that a WP-CLI command might be better. The advantage is that the command runs from php directly on the server (usually has no max execution time, loads different php.ini, etc.) and you don't need to involve the webserver.

If that is not possible, the next best way is probably to [create a custom REST endpoint](https://developer.wordpress.org/rest-api/extending-the-rest-api/adding-custom-endpoints/). WordPress has a class [`WP_REST_Controller`](https://developer.wordpress.org/reference/classes/wp_rest_controller/), usually I write classes that `extend` this and work from there. For simplicity the following example is not using inheritence, but I try to keep to the same lingo.
**1. Register new route**
New/custom routes are registered via [`register_rest_route()`](https://developer.wordpress.org/reference/functions/register_rest_route/) like so
```
$version = 1;
$namespace = sprintf('acme/v%u', $version);
$base = '/import';
\register_rest_route(
$namespace,
$base,
[
[
'methods' => \WP_REST_Server::CREATABLE,
// equals ['POST','PUT','PATCH']
'callback' => [$this, 'import_csv'],
'permission_callback' => [$this, 'get_import_permissions_check'],
'args' => [],
// used for OPTIONS calls, left out for simplicity's sake
],
]
);
```
This will create a new route that you can call via
```
http://www.example.com/wp-json/acme/v1/import/
default REST start-^ ^ ^
namespace with version-| |-base
```
**2. Define permissions check**
Maybe you need authentication? Use nonces?
```
public function get_import_permissions_check($request)
{
//TODO: implement
return true;
}
```
**3. Create your actual endpoint callback**
The method previously defined gets passed a [`WP_REST_Request`](https://developer.wordpress.org/reference/classes/wp_rest_request/) object, use that to access request body, etc. To stay consistent, it is usually best to return a [`WP_REST_Response`](https://developer.wordpress.org/reference/classes/wp_rest_response/) instead of custom printing of JSON or similar.
```
public function import_csv($request)
{
$data = [];
// do stuff
return new \WP_REST_Response($data, 200);
}
```
---
If you do all of this in OOP style, you'll get the following class
```
class Import_CSV
{
/**
* register routes for this controller
*/
public function register_routes()
{
$version = 1;
$namespace = sprintf('acme/v%u', $version);
$base = '/import';
\register_rest_route(
$namespace,
$base,
[
[
'methods' => \WP_REST_Server::CREATABLE,
'callback' => [$this, 'import_csv'],
'permission_callback' => [$this, 'get_import_permissions_check'],
'args' => [],
],
]
);
}
/**
* endpoint for POST|PUT|PATCH /acme/v1/import
*/
public function import_csv($request)
{
$data = [];
// do stuff
return new \WP_REST_Response($data, 200);
}
/**
* check if user is permitted to access the import route
*/
public function get_import_permissions_check($request)
{
//TODO: implement
return true;
}
}
```
But .. still 404? Yes, simply defining the class sadly doesn't work (no autoloading by default :( ), so we need to run `register_routes()` like so (in your plugin file)
```
require_once 'Import_CSV.php';
add_action('rest_api_init', function(){
$import_csv = new \Import_CSV;
$import_csv->register_routes();
});

321,674 | <p>I don't understand why my request to WooCommerce API doesn't work.
My usage on react App via axios:</p>
<p>First try:</p>
<pre><code>return axios.get( 'http://domain/wp-json/wc/v3/products?featured=true',
{
headers: {
'consumer_key': 'ck_xxx',
'consumer_secret': 'cs_xxx',
'key_id': 111,
'key_permissions': 'read_write',
'user_id': 111,
}
)
</code></pre>
<p>Second one:</p>
<pre><code>return axios( {
url: 'http://domain/wp-json/wc/v3/products?featured=true',
headers: {
'origin': 'http;//localhost:3000',
'consumer_key': 'ck_x',
'consumer_secret': 'cs_x',
'key_id': 111,
'key_permissions': 'read_write',
'user_id': 111,
},
method: 'GET',
}
} )
</code></pre>
<p>And I get CORS error. But using Insomnia software I create a GET request to <code>http://domain/wp-json/wc/v3/products?featured=true</code> with Basic Auth tab:</p>
<pre><code>USERNAME ck_x
PASSWORD cs_x

| I don't understand why my request to WooCommerce API doesn't work.
My usage on react App via axios:
First try:
```
return axios.get( 'http://domain/wp-json/wc/v3/products?featured=true',
{
headers: {
'consumer_key': 'ck_xxx',
'consumer_secret': 'cs_xxx',
'key_id': 111,
'key_permissions': 'read_write',
'user_id': 111,
}
)
```
Second one:
```
return axios( {
url: 'http://domain/wp-json/wc/v3/products?featured=true',
headers: {
'origin': 'http;//localhost:3000',
'consumer_key': 'ck_x',
'consumer_secret': 'cs_x',
'key_id': 111,
'key_permissions': 'read_write',
'user_id': 111,
},
method: 'GET',
}
} )
```
And I get CORS error. But using Insomnia software I create a GET request to `http://domain/wp-json/wc/v3/products?featured=true` with Basic Auth tab:
```
USERNAME ck_x
PASSWORD cs_x
```
therefore response status is 200 OK.
I appreciate to understand what I'm doing wrong in axios inside my React App. | I was having the same issue with Woocommerce Oauth 1.0 authentication and [this solution](https://stackoverflow.com/a/45465247/2550766) worked for me. I'm running it on localhost, so far so good.
**Edit:**
Let me elaborate this answer a bit more. I just started learning React last night and the best way to learn is by doing. I'll explain as a newbie for a newbie. Here we go...
I created this *Woocommerce helper object* that can be called from any component and it does all the hard work for you:
**`Woocommerce.js`**
```
import axios from "axios";
import Oauth from "oauth-1.0a";
import CryptoJS from "crypto-js";
import jQuery from "jquery";
const ck = "ck_...";
const cs = "cs_...";
const baseURL = "http://yourdomain.com/wp-json";
const Woocommerce = {
getProducts: () => {
return makeRequest("/wc/v3/products");
},
getProductByID: id => {
return makeRequest("/wc/v3/products/" + id);
}
};
function makeRequest(endpoint, method = "GET") {
const oauth = getOauth();
const requestData = {
url: baseURL + endpoint,
method
};
const requestHTTP =
requestData.url + "?" + jQuery.param(oauth.authorize(requestData));
return axios.get(requestHTTP);
}
function getOauth() {
return Oauth({
consumer: {
key: ck,
secret: cs
},
signature_method: "HMAC-SHA1",
hash_function: function(base_string, key) {
return CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA1(base_string, key));
}
});
}
export default Woocommerce;
```
You will need to install all the necessary packages by running the commands:
```
npm install axios jquery crypto-js
npm install oauth-1.0a --production
```
**How to use it**
First import it to the component:
```
import Woocommerce from "./functions/Woocommerce";
```
Then from inside the component you can call it like this to get all the products:
```
// All products (array of objects)
state = { products: [], isLoaded: false };
componentWillMount() {
Woocommerce.getProducts().then(res =>
this.setState({ products: res.data, isLoaded: true })
);
}
```
Or, to get only one product by ID, you can do:
```
// Single product (object)
state = { product: {}, isLoaded: false };
componentWillMount() {
Woocommerce.getProductByID(123).then(res =>
this.setState({ product: res.data, isLoaded: true })
);
}
```
As you can probably see, you can elaborate more functions inside of the Woocommerce helper and retrieve products using the Woocommerce REST API as you wish.

**UPDATE #2 - Address Email Not Being Received**
Based on your update, your issue is email not being received. IMO, that's likely due to the way you're setting the headers. As a result, your email is getting rejected.
As I stated in the original answer, you're better off setting up to send through an SMTP account. That will help you avoid a lot of potential problems.
Regardless of whether you do that or not, you need to fix your header issue. Don't mess with headers unless you absolutely need to. I'd recommend you take that out completely.
If you must leave it in, you need to fix the following:
1. Unless you're changing something, don't declare it.
2. $current\_user is undefined.
3. Pass headers as array values.
4. "From" value in the header is malformed.
**Unless you're changing something, don't declare it.** `wp_mail()` sets any defaults that are not declared. I would suggest you take out the mime type declaration and the content type for sure.
**`$current_user` is undefined** in the code that you posted. Add the following to make sure it's defined:
```
$current_user = wp_get_current_user();
```
**Pass headers as array values**. `wp_mail()` takes either a string or array, but if it's a string, it gets exploded into an array, so you may as well start with an array.
**"From" value in the header is malformed** the way you have it. You must also have a "from" name in addition to the address. It needs to be in the following format:
```
"From: The From Name <[email protected]>"
```
If you don't have the "name", substitute the email address:
```
$headers[] = 'From: ' . $current_user->user_email . '<' . $current_user->user_email . '>';
```
So with those things addressed, here's what I recommend:
```
if ($postID) {
$current_user = wp_get_current_user();
$headers[] = 'From: ' . $current_user->user_email . '<' . $current_user->user_email . '>';
$to = $email;
$title = "Test email from";
$body = "Hello " . $name . " Your ZonPackage " . $package . " Booking Confirmed ." ;
$subject ="Zon Package Booking";
wp_mail( $to, $subject, $body, $headers );
}
```
Keep in mind that may not solve your problem entirely. If your "from" address doesn't have a domain that matches the sending domain, you may still look "spammy" and get rejected. Also, be sure to check your spam folder to see if your messages are being received but are flagged as spam. |

| Somehow when I was working with my local dev environment, I have made some mistakes in some php files which I could not figure it out.
So, I have decided to copy the files from the `public_html` and paste in my local copy of the WordPress..
Now when I open my website in my local machine, it shows the front page without any problem. But when I click on any other links, to visit any other page, it just kicks me back to
```
localhost:8080/dashboard
```
Why this is happening??
I could understand one thing that the permalinks has to be refreshed. But, I could not even access the `localhost:8080/mysite/wp-admin`. Is there any other way, that I can refresh the permalinks??
What is the procedure to take a copy of wordpress website from online server to offline??
PS: I use xmapp with sql and WordPress 4.9.8 | XAMPP dashboard
===============
XAMP has some default files (example files), you should delete that.
It's just there to show you that everything works as expected.
With also an example .htacess which redirects you to dashboard. Before you copy and paste your files, you should have deleted everything in **C:\xampp\htdocs (your htdocs)**
Manual install or automatic
---------------------------
You could install WordPress by yourself, you will need to download WP, create a database and database user and edited the WP config.php file.
You could also just download an Add-on for XAMPP which does this for you: <https://www.apachefriends.org/add-ons.html>
And it will install this in a separate folder **C:\xampp\apps\wordpress\htdocs** which is handy if you want to test other things then only WordPress. |

Any idea what I'm doing wrong there? | Here is an alternative solution. I think it would be cleaner than adding all these if statements and page IDs. You can do this using CSS and the body class WP adds.
For example, go to one of your single pages and look at the class on the body tag. You should see something like page-id-###. Then just simply add a rule in your stylesheet or the CSS customizer.
Something like this...
```
body.page-id-123 .header-inner,
body.page-id-124 .header-inner,
body.page-id-125 .header-inner, {
background-color:#861919!important;
}
```
Here is how you can target some of your other pages.
* All Single Product Pages - body.single-product .header-inner {}
* Specific Single Post - body.postid-### .header-inner {}
* Blog Page - body.blog .header-inner {}
* All Single Blog Pages - body.single-post .header-inner {}
* Etc...
Just inspect each page and you should get the idea.
**Create your own body class**
If needed you could create your own body class by using the body\_class filter, here is a basic example of how to use it. Of course you could do more by adding conditionals or checking for templates.
```
function my_custom_body_class($classes) {
$classes[] = 'foo';
return $classes;
}
add_filter('body_class', 'my_custom_body_class');

321,868 | <p>I have multiple wp_query's on the same page. Each one of those queries has an AJAX "read more" button at the bottom. The problem I'm finding is that I can only get one to work at a time. Whichever function is added first in the functions.php, that one works - the other one gets a 403 error for admin-ajax.php. </p>
<p>I'm pretty new to AJAX, so I've probably made a total hash of it, and I'm sure there's a way to combine this into a single function (preferred!) but if I can even just find a way for them all to work independently, that work be fine.</p>

<p>I'm all up for simplifying this into a single function if possible, or if not, at least getting it to work independently. I'm guessing that it's only viewing 1 wp_nonce's and checking it against both AJAX calls, so the first one it reads is fine, the second is coming up with a 403?</p>

| I have multiple wp\_query's on the same page. Each one of those queries has an AJAX "read more" button at the bottom. The problem I'm finding is that I can only get one to work at a time. Whichever function is added first in the functions.php, that one works - the other one gets a 403 error for admin-ajax.php.
I'm pretty new to AJAX, so I've probably made a total hash of it, and I'm sure there's a way to combine this into a single function (preferred!) but if I can even just find a way for them all to work independently, that work be fine.
Here's my code:
The 2 WP\_Queries in a custom page-work.php template:
First one:
```
<?php
//Find out how many posts
$total_posts = wp_count_posts('smart_maps');
$total_posts = $total_posts->publish;
$number_shown = 0;
$the_query = new WP_Query( $args ); ?>
<?php if ( $the_query->have_posts() ) : ?>
<div id="smartmaps" class="smartmaps col xs-col-14 xs-offset-1 md-col-12 md-offset-2" style="display:none;">
<div class="in-here-smartmaps">
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<a href="<?php echo get_permalink(get_the_ID());?>">
<div class="single-smartmap col xs-col-16 md-col-8">
<div class="col xs-col-8 xs-offset-4 md-col-4 md-offset-0 center">
<div class="image-element">
<img src="<?php the_field('thumbnail_image');?>" class="circle">
<div class="image-overlay circle"></div>
</div>
</div>
<div class="col xs-col-14 xs-offset-1 md-col-10 md-offset-1">
<h5 class="smart-map-title"><?php the_title();?></h5>
<?php if(get_field('icons')) :?>
<div class="block-icons">
<?php if(in_array('Heart', get_field('icons'))) :?>
<span class="icon-heart"></span>
<?php endif;?>
<?php if(in_array('Plant', get_field('icons'))) :?>
<span class="icon-plant"></span>
<?php endif; ?>
<?php if(in_array('Cup', get_field('icons'))) :?>
<span class="icon-cup"></span>
<?php endif;?>
<?php if(in_array('Book', get_field('icons'))) :?>
<span class="icon-book"></span>
<?php endif;?>
</div>
<?php endif;?>
</div>
</div>
</a>
<?php $number_shown++;
endwhile; ?>
<?php endif;?>
</div>
<?php if($number_shown != $total_posts) :?>
<div class="loadmore smarties col xs-col-14 xs-offset-1 md-col-8 md-offset-4 center">
<h3><a href="#">LOAD MORE</a></h3>
</div>
<?php endif;?>
</div>
<div clas="clearfix"></div>
```
The second 1:
```
<div id="strategic-events" class="strategicevents col xs-col-14 xs-offset-1 md-col-12 md-offset-2" style="display:none;">
<div class="in-here-strats">
<?php
//Find out how many posts
$total_posts = wp_count_posts('strategic_events');
$total_posts = $total_posts->publish;
$number_shown = 0;
$args = array( 'post_type' => 'strategic_events', 'posts_per_page' => 10, 'offset' => $the_offset );
$the_query2 = new WP_Query( $args ); ?>
<?php if ( $the_query2->have_posts() ) :
while ( $the_query2->have_posts() ) : $the_query2->the_post(); ?>
<a href="<?php echo get_permalink(get_the_ID());?>">
<div class="single-strategicevent col xs-col-16 md-col-8">
<div class="col xs-col-8 xs-offset-4 md-col-4 md-offset-0 center">
<div class="image-element">
<img src="<?php the_field('strategic_event_image');?>" class="circle">
<div class="image-overlay circle"></div>
</div>
</div>
<div class="col xs-col-14 xs-offset-1 md-col-10 md-offset-1">
<h5 class="strategic-event-title"><?php the_title();?></h5>
<?php if(get_field('subtitle')) :?>
<p><?php the_field('subtitle');?></p>
<small><?php the_field('location_text');?></small>
<?php endif;?>
</div>
</div>
</a>
<?php $number_shown++;
endwhile;
endif; ?>
</div>
<?php if($number_shown != $total_posts) :?>
<div class="loadmore strats col xs-col-14 xs-offset-1 md-col-8 md-offset-4 center">
<h3><a href="#">LOAD MORE</a></h3>
</div>
<?php endif;?>
</div>
<div class="clearfix"></div>
```
My JS code (both also in the page-work.php for now)...
```
<script>
var ajaxurl = "<?php echo admin_url( 'admin-ajax.php' ); ?>";
var page = 2;
jQuery(function($) {
$('body').on('click', '.loadmore.strats', function(e) {
e.preventDefault();
var data = {
'action': 'load_posts_by_ajax',
'page': page,
'security': '<?php echo wp_create_nonce("load_strats_posts"); ?>',
'max_page': '<?php global $wp_query; echo $wp_query->max_num_pages;?>'
};
$.post(ajaxurl, data, function(response) {
$('.in-here-strats').append(response);
page++;
});
});
});
```
```
<script>
var ajaxurl = "<?php echo admin_url( 'admin-ajax.php' ); ?>";
var page = 2;
jQuery(function($) {
$('body').on('click', '.loadmore.smarties', function(e) {
e.preventDefault();
var data = {
'action': 'load_posts_by_ajax',
'page': page,
'security2': '<?php echo wp_create_nonce("load_smartmaps_posts"); ?>',
'max_page': '<?php global $wp_query; echo $wp_query->max_num_pages;?>'
};
$.post(ajaxurl, data, function(response) {
$('.in-here-smartmaps').append(response);
page++;
});
});
});
</script>
```
And the AJAX functions in my function.php:
```
//Load More Smart Maps
add_action('wp_ajax_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
function load_smart_maps_by_ajax_callback() {
check_ajax_referer('load_smartmaps_posts', 'security2');
$paged = $_POST['page'];
$args = array(
'post_type' => 'smart_maps',
'post_status' => 'publish',
'posts_per_page' => '10',
'paged' => $paged,
);
$my_posts = new WP_Query( $args );
if ( $my_posts->have_posts() ) :
?>
<?php
$total_posts = wp_count_posts('smart_maps');
$total_posts = $total_posts->publish;
$number_shown = $paged * 10 - 10;?>
<?php while ( $my_posts->have_posts() ) : $my_posts->the_post() ?>

I'm all up for simplifying this into a single function if possible, or if not, at least getting it to work independently. I'm guessing that it's only viewing 1 wp\_nonce's and checking it against both AJAX calls, so the first one it reads is fine, the second is coming up with a 403? | >

Yes, because both your PHP functions (or AJAX callbacks) there are hooked to the *same* AJAX action, which is `load_posts_by_ajax`:
```
// #1 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_strats_by_ajax_callback');
```
And `check_ajax_referer()` by default exits the page with a `403` ("forbidden") status, when for example the nonce is not specified or has already expired:
```
// #1 $_REQUEST['security2'] will be checked for the load_smartmaps_posts nonce action.
check_ajax_referer('load_smartmaps_posts', 'security2');
// #2 $_REQUEST['security'] will be checked for the load_strats_posts nonce action.
check_ajax_referer('load_strats_posts', 'security');
```
You can send both nonces (although nobody would do that), or you can use the same nonce and same `$_REQUEST` key (e.g. `security`), but you'd still get an unexpected results/response.
So if you want a "single function", you can use a *secondary "action"*:
1. PHP part in `functions.php`:
```
// #1 Load More Smart Maps
// No add_action( 'wp_ajax_...' ) calls here.
function load_smart_maps_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
// #2 Load More Strategic Events
// No add_action( 'wp_ajax_...' ) calls here.
function load_strats_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
add_action( 'wp_ajax_load_posts_by_ajax', 'load_posts_by_ajax' );
add_action( 'wp_ajax_nopriv_load_posts_by_ajax', 'load_posts_by_ajax' );
function load_posts_by_ajax() {
check_ajax_referer( 'load_posts_by_ajax', 'security' );
switch ( filter_input( INPUT_POST, 'action2' ) ) {
case 'load_smartmaps_posts':
load_smart_maps_by_ajax_callback();
break;
case 'load_strats_posts':
load_strats_by_ajax_callback();
break;
}
wp_die();
}
```
2. JS part — the `data` object:
```
// #1 On click of `.loadmore.smarties`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_smartmaps_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
// #2 On click of `.loadmore.strats`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_strats_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
```
But why not hook the callbacks to their own specific AJAX action:
```
// #1 AJAX action = load_smart_maps_posts_by_ajax
add_action('wp_ajax_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_strats_posts_by_ajax
add_action('wp_ajax_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');

All I'm really doing is making sure my requester is actually coming from my site. There's no point in generating 17 different nonces for that. Often I stick the nonce into a submission button as a data-attribute, then pull the nonce from that rather than from the wordpress localization scheme. It's more convenient when there are many scripts on a single page and they are accessing some of the same back end functions.</p>\n\n<pre><code>var postData = {};\n var nonce = $('#register_button').attr('data-nonce');\n postData.nonce = nonce;\n postData.action = 'this_is_the_ajax_name';\n$.post( name_the_script_will_see.ajax_url, postData, function( response_data ) { \n\n if ( response_data.success ) {\n alert (\"success\");\n } else {\n alert (\"Error\");\n }\n</code></pre>\n\n<p>Hope this helps! </p>\n"

Yes, because both your PHP functions (or AJAX callbacks) there are hooked to the *same* AJAX action, which is `load_posts_by_ajax`:
```
// #1 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_strats_by_ajax_callback');
```
And `check_ajax_referer()` by default exits the page with a `403` ("forbidden") status, when for example the nonce is not specified or has already expired:
```
// #1 $_REQUEST['security2'] will be checked for the load_smartmaps_posts nonce action.
check_ajax_referer('load_smartmaps_posts', 'security2');
// #2 $_REQUEST['security'] will be checked for the load_strats_posts nonce action.
check_ajax_referer('load_strats_posts', 'security');
```
You can send both nonces (although nobody would do that), or you can use the same nonce and same `$_REQUEST` key (e.g. `security`), but you'd still get an unexpected results/response.
So if you want a "single function", you can use a *secondary "action"*:
1. PHP part in `functions.php`:
```
// #1 Load More Smart Maps
// No add_action( 'wp_ajax_...' ) calls here.
function load_smart_maps_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
// #2 Load More Strategic Events
// No add_action( 'wp_ajax_...' ) calls here.
function load_strats_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
add_action( 'wp_ajax_load_posts_by_ajax', 'load_posts_by_ajax' );
add_action( 'wp_ajax_nopriv_load_posts_by_ajax', 'load_posts_by_ajax' );
function load_posts_by_ajax() {
check_ajax_referer( 'load_posts_by_ajax', 'security' );
switch ( filter_input( INPUT_POST, 'action2' ) ) {
case 'load_smartmaps_posts':
load_smart_maps_by_ajax_callback();
break;
case 'load_strats_posts':
load_strats_by_ajax_callback();
break;
}
wp_die();
}
```
2. JS part — the `data` object:
```
// #1 On click of `.loadmore.smarties`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_smartmaps_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
// #2 On click of `.loadmore.strats`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_strats_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
```
But why not hook the callbacks to their own specific AJAX action:
```
// #1 AJAX action = load_smart_maps_posts_by_ajax
add_action('wp_ajax_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_strats_posts_by_ajax
add_action('wp_ajax_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');

321,974 | <p>I'm developing some custom blocks in the new Gutenberg editor experience, and I'm struggle to understand how to use some build-in components, mostly the Draggable components.</p>
<p>What I would like to achieve is a list of items (let's say many <code>li</code> in a <code>ul</code>) and I want them to be orderable with a drag & drop feature.</p>
<p>Here is my code:</p>
<pre><code>import { __ } from '@wordpress/i18n';
import { registerBlockType } from '@wordpress/blocks';
import { Draggable, Dashicon } from '@wordpress/components';
import './style.scss';
import './editor.scss';
registerBlockType( 'namespace/my-custom-block',
{
title: __( 'Custom block', 'namespace'),
description: __( 'Description of the custom block', 'namespace' ),
category: 'common',
icon: 'clipboard',
keywords: [
__( 'list', 'namespace' ),
__( 'item', 'namespace' ),
__( 'order', 'namespace' )
],
supports: {
html: false,
multiple: false,
},
attributes: {
items: {
type: 'array',
default: [ 'One' ,'Two' ,'Tree' ,'Four' ,'Five' ,'Six' ,'Seven' ,'Eight' ,'Nine' ,'Ten' ]
}
},
edit: props => {
return (
<ul>
{ props.attributes.items.map( (itemLabel, id) => (
<li id={ `li_${id}` } draggable>
<Draggable
elementId={ `li_${id}` }
transferData={ {} }>
{
({ onDraggableStart, onDraggableEnd }) => (
<Dashicon
icon="move"
onDragStart={ onDraggableStart }
onDragEnd={ onDraggableEnd }
draggable

)
}
</Draggable>
{ itemLabel }
</li>
))
}
</ul>
)
},
save: () => {
// Return null to be rendered on the server
return null;
}
}
)
</code></pre>
<p>On the backend side it is correctly rendered but the items are not draggable</p>
<p><a href="https://i.stack.imgur.com/QMSVd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QMSVd.png" alt="enter image description here"></a></p>
<p>Unfortunately the gutenberg developer handbook doesn't give much info
<a href="https://wordpress.org/gutenberg/handbook/designers-developers/developers/components/draggable/" rel="nofollow noreferrer">https://wordpress.org/gutenberg/handbook/designers-developers/developers/components/draggable/</a> and I'm not seeing how should I do it.</p>

| I'm developing some custom blocks in the new Gutenberg editor experience, and I'm struggle to understand how to use some build-in components, mostly the Draggable components.
What I would like to achieve is a list of items (let's say many `li` in a `ul`) and I want them to be orderable with a drag & drop feature.
Here is my code:
```
import { __ } from '@wordpress/i18n';
import { registerBlockType } from '@wordpress/blocks';
import { Draggable, Dashicon } from '@wordpress/components';
import './style.scss';
import './editor.scss';
registerBlockType( 'namespace/my-custom-block',
{
title: __( 'Custom block', 'namespace'),
description: __( 'Description of the custom block', 'namespace' ),
category: 'common',
icon: 'clipboard',
keywords: [
__( 'list', 'namespace' ),
__( 'item', 'namespace' ),
__( 'order', 'namespace' )
],
supports: {
html: false,
multiple: false,
},
attributes: {
items: {
type: 'array',
default: [ 'One' ,'Two' ,'Tree' ,'Four' ,'Five' ,'Six' ,'Seven' ,'Eight' ,'Nine' ,'Ten' ]
}
},
edit: props => {
return (
<ul>
{ props.attributes.items.map( (itemLabel, id) => (
<li id={ `li_${id}` } draggable>
<Draggable
elementId={ `li_${id}` }
transferData={ {} }>
{
({ onDraggableStart, onDraggableEnd }) => (
<Dashicon
icon="move"
onDragStart={ onDraggableStart }
onDragEnd={ onDraggableEnd }
draggable
/>
)
}
</Draggable>
{ itemLabel }
</li>
))
}
</ul>
)
},
save: () => {
// Return null to be rendered on the server
return null;
}
}
)
```
On the backend side it is correctly rendered but the items are not draggable

Unfortunately the gutenberg developer handbook doesn't give much info
<https://wordpress.org/gutenberg/handbook/designers-developers/developers/components/draggable/> and I'm not seeing how should I do it.
Thanks and cheers | >

Yes, because both your PHP functions (or AJAX callbacks) there are hooked to the *same* AJAX action, which is `load_posts_by_ajax`:
```
// #1 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_posts_by_ajax
add_action('wp_ajax_load_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_strats_by_ajax_callback');
```
And `check_ajax_referer()` by default exits the page with a `403` ("forbidden") status, when for example the nonce is not specified or has already expired:
```
// #1 $_REQUEST['security2'] will be checked for the load_smartmaps_posts nonce action.
check_ajax_referer('load_smartmaps_posts', 'security2');
// #2 $_REQUEST['security'] will be checked for the load_strats_posts nonce action.
check_ajax_referer('load_strats_posts', 'security');
```
You can send both nonces (although nobody would do that), or you can use the same nonce and same `$_REQUEST` key (e.g. `security`), but you'd still get an unexpected results/response.
So if you want a "single function", you can use a *secondary "action"*:
1. PHP part in `functions.php`:
```
// #1 Load More Smart Maps
// No add_action( 'wp_ajax_...' ) calls here.
function load_smart_maps_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
// #2 Load More Strategic Events
// No add_action( 'wp_ajax_...' ) calls here.
function load_strats_by_ajax_callback() {
// No need to call check_ajax_referer()
...your code here...
}
add_action( 'wp_ajax_load_posts_by_ajax', 'load_posts_by_ajax' );
add_action( 'wp_ajax_nopriv_load_posts_by_ajax', 'load_posts_by_ajax' );
function load_posts_by_ajax() {
check_ajax_referer( 'load_posts_by_ajax', 'security' );
switch ( filter_input( INPUT_POST, 'action2' ) ) {
case 'load_smartmaps_posts':
load_smart_maps_by_ajax_callback();
break;
case 'load_strats_posts':
load_strats_by_ajax_callback();
break;
}
wp_die();
}
```
2. JS part — the `data` object:
```
// #1 On click of `.loadmore.smarties`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_smartmaps_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
// #2 On click of `.loadmore.strats`
var data = {
'action': 'load_posts_by_ajax',
'action2': 'load_strats_posts',
'security': '<?php echo wp_create_nonce( "load_posts_by_ajax" ); ?>', // same nonce
...other properties...
};
```
But why not hook the callbacks to their own specific AJAX action:
```
// #1 AJAX action = load_smart_maps_posts_by_ajax
add_action('wp_ajax_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
add_action('wp_ajax_nopriv_load_smart_maps_posts_by_ajax', 'load_smart_maps_by_ajax_callback');
// #2 AJAX action = load_strats_posts_by_ajax
add_action('wp_ajax_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');
add_action('wp_ajax_nopriv_load_strats_posts_by_ajax', 'load_strats_by_ajax_callback');

| I am trying to invert the order of `<li>` and `<a>` in a `wp_nav_menu`, since for a responsive mobile design I like more when the click is done in all the `<li>` and not only in the word / s of the link `<a>` because is easier for the finger.
Thank you.
PS: I must say that I am a newbie in Wordpress development.
This is the code I use:
```
<div id="header-menu-nav">
<nav>
<?php
wp_nav_menu(array(
'container'=> false,
'items_wrap' => '<ul>%3$s</ul>',
'theme_location' => 'menu'
));
?>
</nav>
</div>
```
And the answer I get is:
```
<div id="header-menu-mobile-nav">
<nav>
<ul id="header-menu-mobile-nav-ul">
<li class="menu-item menu-item-type-custom menu-item-object-custom menu-item-181">
<a href="index.php">Home</a>
</li>
</ul>
</nav>
</div>
```
What I want is:
```
<div id="header-menu-mobile-nav">
<nav>
<ul id="header-menu-mobile-nav-ul">
<a href="index.php">
<li class="menu-item menu-item-type-custom menu-item-object-custom menu-item-181">Home</li>
</a>
</ul>
</nav>
</div>
``` | ```
<ul>
<a>
<li></li>
</a>
</ul>
```

[](https://i.stack.imgur.com/v5rVQ.png) | Yes, this can easily be cleaned up with a little CSS. You can start by using the browser's inspector, hit F12 to open it, and select the element you want to style.
See if that form or something around has an ID, use that to target each element so you don't effect other pages or unwanted elements.
Here are couple example that might help.
```
#myFormID label,
#myFormID input[type="text"],
#myFormID select {
display: block;
}
```
That will put your labels and form elements on different lines.
The best thing to do is just inspect the page and start playing around with the CSS. |

| I'm writing a standalone script for Wordpress so I can display things like the username on a page outside of Wordpress.
My method so far is to try to include or require wp-load.php in my script directory. I've tried
```
chdir ( ".." );
include "wp-load.php";
```
as well as absolute paths to the web root where Wordpress is located for both the chdir and the include. I don't get any errors but wp\_get\_current\_user() always returns empty.
If I move my script up a level to the same folder with Wordpress it works fine. How can I include wp-load.php and keep all of the files in my subfolder?
EDIT: file structure
* public\_html (wordpress is installed here so wp-load.php is also here)
+ myScript (directory)
- script.php
- This is where I try to use chdir ( ".." ) or include ( "../wp-load.php" ) without success | you can try doing a manual update, so as long as you didn't make any changes to the WordPress core files(if you did I suggest you take note of them and reapply after the upgrade), just head over to WordPress.org download the latest WordPress package and copy it over to your root folder on the server make sure you overwrite only the core WordPress files, leave the wp-content folder out of this, input your details to the wp-config.php file and that should probably sort this issue out for you.
PS. remember to back up your database and original WordPress folders before continuing. |

| I'm trying to change the logo url for some categories and pages. In the Theme options there is the possibility to change the logo img for categories and pages, but can't change the logo url. I have tried this code in my child theme function.php file but it is not working:
```
function change_logo_url_animacao($html) {
$custom_logo_id = get_theme_mod( 'custom_logo' );
$url = home_url( 'pimeanimacao', 'relative' );
if(is_page( array( 6447, 7 ) )){
$html = sprintf( '<a href="%1$s">%2$s</a>',
esc_url( $url ),
wp_get_attachment_image( $custom_logo_id, 'full', false, array(
'class' => 'custom-logo',))
);
}elseif(is_category( 39 ) || cat_is_ancestor_of( 39, get_query_var( 'cat' ) )){
$html = sprintf( '<a href="%1$s">%2$s</a>',
esc_url( $url ),
wp_get_attachment_image( $custom_logo_id, 'full', false, array(
'class' => 'custom-logo',))
);

$html = sprintf( '<a href="%1$s">%2$s</a>',
esc_url( $url ),

'class' => 'custom-logo',))
);
}
return $html;
}
add_filter('get_custom_logo','change_logo_url_animacao');
```
The header I'm using have this code to load the logo:
```
<div class="contact_logo">
<?php xxx_show_logo(true, true); ?>
</div>
```
And the function called here xxx\_show\_logo in in the file core.theme.php of the framework. Here is the funcion:
```

}
}

in some categories and pages to this link "site\_domain/pimeanimacao".
How can I solve it?
Thank you in advance for helping me! | It's possible to have them share the same slug, but you need to manually resolve conflicts yourself. You have to check if the end of the requested URL is an existing term, and reset the query vars accordingly if it's not found:
```
function wpd_post_request_filter( $request ){
if( array_key_exists( 'category_name' , $request )
&& ! get_term_by( 'slug', basename( $request['category_name'] ), 'category' ) ){
$request['name'] = basename( $request['category_name'] );
$request['post_type'] = 'post';
unset( $request['category_name'] );
}
return $request;
}
add_filter( 'request', 'wpd_post_request_filter' );
```
The obvious downsides to this are an extra trip to the database for every post or category view, and the inability to have a category slug that matches a post slug. |

It works,but I don`t want to show **it** on my home page.
How can I do ? | You can check for your "home page" at the start of your function by using `is_home()` and/or `is_front_page()` and just return original content without date. See [is\_home vs is\_front\_page](https://wordpress.stackexchange.com/questions/30385/when-to-use-is-home-vs-is-front-page)
```
function wpb_last_updated_date( $content ) {
if ( is_home() || is_front_page() ) return $content; //homepage return content without date
// your original function code
}
```
Alterantively you could embes your add\_filter in an if statement |

| I have been looking around for the answer but did not find any.
I am creating an `iframe` payment gateway while the iframe is loaded inside the checkout page. My goal is once the customer clicks on a certain button, the function which validates that the customer has filled all the required input is triggered and if it returns `true` the iframe loads.
Otherwise, the notice from the validating function is triggered.
I found the function as a method called `update_checkout_action` inside the `wc_checkout_form` class.
Hope it's enough information, if needed any more, please let me know and I'll provide.
Thanks. | I ran into this a few times, I have yet to find a straight forward method of handling it. But here is what I've done in the past.
You can trigger checkout validation easily by forcing a click on the submit button.
```
$('#myButton').on('click', function(){
$('#place_order').click();
});
```
However, this isn't really useful for you because it will just submit the order if there are no errors.
There is also the checkout\_error callback, but it only fires if there is a error.
```
$(document.body).on('checkout_error', function () {
// There was a validation error
});
```
Here is what we need to do.
* Detect when the submit button is clicked
* Check for errors
* If there are errors let Woo handle them as normal
* If there are No errors, stop the order from completing
* Show your iframe
* ... Re-Validate / Re-submit Order
---
---
As soon as the submit button is clicked, we can add a hidden field and set the value to 1. We can detect the submit event by using checkout\_place\_order. This should go in your JS file.
```
var checkout_form = $('form.woocommerce-checkout');
checkout_form.on('checkout_place_order', function () {
if ($('#confirm-order-flag').length == 0) {
checkout_form.append('<input type="hidden" id="confirm-order-flag" name="confirm-order-flag" value="1">');
}
return true;
});
```
Now, add a function to functions.php that will check that hidden input and stop the order if the value == 1. It stops the order by adding an error.
```
function add_fake_error($posted) {
if ($_POST['confirm-order-flag'] == "1") {
wc_add_notice( __( "custom_notice", 'fake_error' ), 'error');
}
}
add_action('woocommerce_after_checkout_validation', 'add_fake_error');
```
Back in our JS file, we can use the checkout\_error callback, if it has 1 error we know it was the fake error we created so we can show the iframe. If it has more than 1 error it means there are other real errors on the page.
```
$(document.body).on('checkout_error', function () {
var error_count = $('.woocommerce-error li').length;
if (error_count == 1) { // Validation Passed (Just the Fake Error Exists)
// Show iFrame
}else{ // Validation Failed (Real Errors Exists, Remove the Fake One)
$('.woocommerce-error li').each(function(){
var error_text = $(this).text();
if (error_text == 'custom_notice'){
$(this).css('display', 'none');
}
});
}
});
```
In the commented out section, // Show iFrame, I would probably open in it in a lightbox. At some point you will need another submit button that triggers the form submit and set the hidden input.
```
$('#confirm-order-button').click(function () {
$('#confirm-order-flag').val('');
$('#place_order').trigger('click');
});

);
return $schedules;
}
add_filter( 'cron_schedules', 'cron_add_weekly' );

}

$value = 91;
update_user_meta($value + 1, 'from_cron', 'updated');
}
```
The user meta ought to be updated every 5 seconds after refreshing the page. But the cron runs only the first time | OK, so I've tested your code and I'm pretty sure it can't run even once... And here's why...
If you'll take a look at [`wp_schedule_event`](https://core.trac.wordpress.org/browser/tags/5.0/src/wp-includes/cron.php#L97) you'll see this check at the top of the function:
```
if ( !isset( $schedules[$recurrence] ) )
return false;
```
It means that you can't schedule event with unknown recurrence.
So let's go back to your code... What it does is:
* adds your custom recurrence (using `cron_schedules` hook),
* schedules an event with that recurrence during plugin activation.
Everything look good, right? Well, no - it does not.
Activation hook is fired during plugin activation. So that plugin is not working before the activation is run. So your custom recurrence is not registered. So... your hook is not scheduled. I've tested that and the result of `wp_schedule_event` in your activation hook is false, so the event is not scheduled.
So what to do?
--------------
Simple - don't schedule your event on activation hook, if you want to use custom recurrence.
So here's your safer code:
```
register_deactivation_hook(__FILE__, 'my_deactivation');
function my_deactivation() {
wp_clear_scheduled_hook('cron_every_5_seconds');
}
function add_every_5_seconds_cron_schedule( $schedules ) {
$schedules['every_5_seconds'] = array(
'interval' => 5,
'display' => __( 'Every 5 Seconds', 'textdomain' )
);
return $schedules;
}
add_filter( 'cron_schedules', 'add_every_5_seconds_cron_schedule' );
function schedule_my_cron_events() {
if ( ! wp_next_scheduled( 'cron_every_5_seconds') ) {
wp_schedule_event( time(), 'every_5_seconds', 'cron_every_5_seconds' );
}
}
add_action( 'init', 'schedule_my_cron_events' );
function cron_every_5_seconds_action() {
$value = 91;
update_user_meta( $value + 1, 'from_cron', 'updated' );
}
add_action( 'cron_every_5_seconds', 'cron_every_5_seconds_action' );
```

| I'm trying to load external content into an iframe, & it is working in Chrome & Firefox, but it won't load in Safari. In Safari I get the error message:
>
> Refused to display 'my\_content' in a frame because it set
> 'X-Frame-Options' to 'sameorigin'
>
>

I think the issue may be that my WordPress install is in a subdirectory:
* WordPress Address (URL): <https://example.com/wp>
* Site Address (URL): <https://example.com>
The header for my external content includes the following:
```
X-Frame-Options: sameorigin
Content-Security-Policy: frame-ancestors 'self' https://example.com
X-Content-Security-Policy: frame-ancestors 'self' https://example.com
```
This article lists a number of possible reasons for the issue with Safari & SAMEORIGIN <https://halfelf.org/2018/safari-and-sameorigin/>. I don't have any extra X-Frame-Options in my .htaccess file, so I'm wondering if the issue is related to my WordPress install being located in a subdirectory. Is there a workaround for this? Or is this caused by something else? | This is a know issue with WP Update 5.02.

| This theme I was handed from another dev company is littered with `add_action/filter( 'hook/filter', create_function( '', 'return blah('blah')' );` We will be moving this site to a server running `php 7.2`.
I am wondering what's the appropriate method to remove these actions and filters. Or can I simply just copy and paste the /path/to/file in the child directory and know that this will be overwritten?

```
if ( ! function_exists( 'ot_register_theme_options_page' ) ) {
function ot_register_theme_options_page() {

$get_settings = _ut_theme_options();

);
// Filters the options.php to add the minimum user capabilities.
add_filter( 'option_page_capability_option_tree', create_function( '$caps', "return '$caps';" ), 999 );
}
}
}
```
I'm aware the appropriate `add_filter` would come out to being `add_filter( 'option_page_capability_option_tree', function($caps) { return $caps; }, 999);` | In order to remove the hooks and filters, we need to be able to get a reference to the callable that was added, but in this case, `create_function` was used, so that's extremely difficult. It's also the reason you're getting deprecation notices. Sadly the only way to fix those deprecations is to change the parent theme to fix it.
### Fixing The Deprecations
The PHP docs say that `create_function` works like this:
>
>
> ```
> string create_function ( string $args , string $code )
>
> ```
>
> Creates an anonymous function from the parameters passed, and returns a unique name for it.
>
>
>
And of note, `create_function` is deprecated in PHP 7.2
So this:
```
create_function( '$a', 'return $a + 1;' )
```
Becomes:
```
function( $a ) {
return $a + 1;
}
```
Or even
```
function add_one( $a ) {
return $a + 1;
}
```
This should eliminate the `create_function` calls, and turn the anonymous functions into normal calls that can be removed in a child theme
### Removing The Hooks and Filters
Now that we've done that, we can now remove and replace them in the child theme.
To do this, we need 2 things:
* to run the removal code **after** they were added
* to be able to unhook the filters/actions
Putting your replacement in is easy, just use `add_filter` and `add_action`, but that adds your version, we need to remove the parent themes version.
Lets assume that this code is in the parent theme:
```
add_filter('wp_add_numbers_together' 'add_one' );
```
And that we want to replace it with a `multiply_by_two` function. First lets do this on the `init` hook:
```php
function nickm_remove_parent_hooks() {
//
}
add_action('init', 'nickm_remove_parent_hooks' );
```
Then call `remove_filter and` add\_filter`:
```php
function nickm_remove_parent_hooks() {
remove_filter( 'wp_add_numbers_together' 'add_one' );
}
add_action( 'init', 'nickm_remove_parent_hooks' );
add_action( 'wp_add_numbers_together', 'multiply_by_two' );
```
Keep in mind that child themes let you override templates, but `functions.php` is not a template, and child themes don't change how `include` or `require` work. A child themes `functions.php` is loaded first, but otherwise, they're similar to plugins.
### And Finally
You shouldn't be registering post types, roles, capabilities, and taxonomies in a theme, it's a big red flag and creates lock in, preventing data portability. These things are supposed to be in plugins, not themes |

| I want to export some specific posts from my database (csv or sql) and then replace content to these and import them back without changing the id number of the posts.I s this possible to do it and if it is, how?
Thank you in advance. | In order to remove the hooks and filters, we need to be able to get a reference to the callable that was added, but in this case, `create_function` was used, so that's extremely difficult. It's also the reason you're getting deprecation notices. Sadly the only way to fix those deprecations is to change the parent theme to fix it.
### Fixing The Deprecations
The PHP docs say that `create_function` works like this:
>
>
> ```
> string create_function ( string $args , string $code )
>
> ```
>
> Creates an anonymous function from the parameters passed, and returns a unique name for it.
>
>
>
And of note, `create_function` is deprecated in PHP 7.2
So this:
```
create_function( '$a', 'return $a + 1;' )
```
Becomes:
```
function( $a ) {
return $a + 1;
}
```
Or even
```
function add_one( $a ) {
return $a + 1;
}
```
This should eliminate the `create_function` calls, and turn the anonymous functions into normal calls that can be removed in a child theme
### Removing The Hooks and Filters
Now that we've done that, we can now remove and replace them in the child theme.
To do this, we need 2 things:
* to run the removal code **after** they were added
* to be able to unhook the filters/actions
Putting your replacement in is easy, just use `add_filter` and `add_action`, but that adds your version, we need to remove the parent themes version.
Lets assume that this code is in the parent theme:
```
add_filter('wp_add_numbers_together' 'add_one' );
```
And that we want to replace it with a `multiply_by_two` function. First lets do this on the `init` hook:
```php
function nickm_remove_parent_hooks() {
//
}
add_action('init', 'nickm_remove_parent_hooks' );
```
Then call `remove_filter and` add\_filter`:
```php
function nickm_remove_parent_hooks() {
remove_filter( 'wp_add_numbers_together' 'add_one' );
}
add_action( 'init', 'nickm_remove_parent_hooks' );
add_action( 'wp_add_numbers_together', 'multiply_by_two' );
```
Keep in mind that child themes let you override templates, but `functions.php` is not a template, and child themes don't change how `include` or `require` work. A child themes `functions.php` is loaded first, but otherwise, they're similar to plugins.
### And Finally
You shouldn't be registering post types, roles, capabilities, and taxonomies in a theme, it's a big red flag and creates lock in, preventing data portability. These things are supposed to be in plugins, not themes |

| I would like to understand the best practices regarding nonce validation in REST APIs.

(I mean validate\_callback for a arg? permission\_callback?) | You should pass the special `wp_rest` nonce as part of the request. Without it, the `global $current_user` object will not be available in your REST class. You can pass this from several ways, from $\_GET to $\_POST to headers.
The action nonce is optional. If you add it, you can't use the REST endpoint from an external server, only from requests dispatched from within WordPress itself. The user can authenticate itself using [Basic Auth](https://github.com/WP-API/Basic-Auth), [OAuth2](https://github.com/WP-API/OAuth2), or [JWT](https://github.com/WP-API/jwt-auth) from an external server even without the `wp_rest` nonce, but if you add an action nonce as well, it won't work.
So the action nonce is optional. Add it if you want the endpoint to work locally only.

wp_enqueue_script( 'main-js' );

console.log(results);
alert("Success!");
}).fail(function (xhr) {
console.log(results);
alert("Error!");
});
});

Supplying an incorrect nonce will still throw an error.</p>\n<p>The reason for this is that the <code>rest_cookie_check_errors</code> which is what does the verification will simply set the <code>current_user</code> to empty if no nonce is provided. This works fine when a user is required, but not otherwise. (see: <a href=\"https://developer.wordpress.org/reference/functions/rest_cookie_check_errors/\" rel=\"nofollow noreferrer\">https://developer.wordpress.org/reference/functions/rest_cookie_check_errors/</a>)</p>\n<p>If you want to expand on Lucas' answer to also include annonymous end points, then you can add a manual nonce check to the start of your end point, like this:</p>\n<pre><code>if ( !$_SERVER['HTTP_X_WP_NONCE'] || !wp_verify_nonce( $_SERVER['HTTP_X_WP_NONCE'], 'wp_rest' ) ) {\n header('HTTP/1.0 403 Forbidden');\n exit;\n}\n</code></pre>\n"

Can i know why? any alternative solution for this? | You should pass the special `wp_rest` nonce as part of the request. Without it, the `global $current_user` object will not be available in your REST class. You can pass this from several ways, from $\_GET to $\_POST to headers.
The action nonce is optional. If you add it, you can't use the REST endpoint from an external server, only from requests dispatched from within WordPress itself. The user can authenticate itself using [Basic Auth](https://github.com/WP-API/Basic-Auth), [OAuth2](https://github.com/WP-API/OAuth2), or [JWT](https://github.com/WP-API/jwt-auth) from an external server even without the `wp_rest` nonce, but if you add an action nonce as well, it won't work.
So the action nonce is optional. Add it if you want the endpoint to work locally only.
Example:
```
/**
* First step, registering, localizing and enqueueing the JavaScript
*/
wp_register_script( 'main-js', get_template_directory_uri() . '/js/main.js', [ 'jquery' ] );
wp_localize_script( 'main-js', 'data', [
'rest' => [
'endpoints' => [
'my_endpoint' => esc_url_raw( rest_url( 'my_plugin/v1/my_endpoint' ) ),
],
'timeout' => (int) apply_filters( "my_plugin_rest_timeout", 60 ),
'nonce' => wp_create_nonce( 'wp_rest' ),
//'action_nonce' => wp_create_nonce( 'action_nonce' ),
],
] );
wp_enqueue_script( 'main-js' );
/**
* Second step, the request on the JavaScript file
*/
jQuery(document).on('click', '#some_element', function () {
let ajax_data = {
'some_value': jQuery( ".some_value" ).val(),
//'action_nonce': data.rest.action_nonce
};
jQuery.ajax({
url: data.rest.endpoints.my_endpoint,
method: "GET",
dataType: "json",
timeout: data.rest.timeout,
data: ajax_data,
beforeSend: function (xhr) {
xhr.setRequestHeader('X-WP-Nonce', data.rest.nonce);
}
}).done(function (results) {
console.log(results);
alert("Success!");
}).fail(function (xhr) {
console.log(results);
alert("Error!");
});
});
/**
* Third step, the REST endpoint itself
*/
class My_Endpoint {
public function registerRoutes() {
register_rest_route( 'my_plugin', 'v1/my_endpoint', [
'methods' => WP_REST_Server::READABLE,
'callback' => [ $this, 'get_something' ],
'args' => [
'some_value' => [
'required' => true,
],
],
'permission_callback' => function ( WP_REST_Request $request ) {
return true;
},
] );
}
/**
* @return WP_REST_Response
*/
private function get_something( WP_REST_Request $request ) {
//if ( ! wp_verify_nonce( $request['nonce'], 'action_nonce' ) ) {
// return false;
//}
$some_value = $request['some_value'];
if ( strlen( $some_value ) < 5 ) {
return new WP_REST_Response( 'Sorry, Some Value must be at least 5 characters long.', 400 );
}
// Since we are passing the "X-WP-Nonce" header, this will work:
$user = wp_get_current_user();
if ( $user instanceof WP_User ) {
return new WP_REST_Response( 'Sorry, could not get the name.', 400 );
} else {
return new WP_REST_Response( 'Your username name is: ' . $user->display_name, 200 );
}
}
}

| I am looking for a good approach regarding the creation of custom post types in WordPress, using object orientation. How can I create CPTs in an clean, organized way?
Take into consideration these 3 scenarios:
1. Plugin for distribution (5.2 compatible)
2. Theme for distribution
3. Own project, with total control over the PHP version and dependencies | I'll answer **scenario #3**, even though it can be adapted for scenarios #1 and #2, too.
WordPress codex [recommends](https://codex.wordpress.org/Post_Types#A_word_about_custom_post_types_as_a_plugin) that we create Custom Post Types (CPTs) in a plugin. Following that recommendation, I will write my answer using modern PHP, which is not meant for a distributed plugin, but rather for own projects where you have control over the PHP version running.
In the example code bellow, I will use raw examples just to give an idea of the architecture behind the creation of CPTs in a OOP manner, but in a real project, "my-plugin" would be something like "my-project", and the creation of CPTs would be a sort of module of that plugin.
**my-plugin/my-plugin.php**
```
<?php
/**
* Plugin name: My Custom Post Types
*/
namespace MyPlugin;
use MyPlugin/CPT/Car;
// ... Composer autoload or similar here
Car::register();
```
**my-plugin/CPT/Car.php**
```
<?php
namespace MyPlugin\CPT;
/**
* Class Car
*
* Handles the creation of a "Car" custom post type
*/
class Car
{
public static function register()
{
$instance = new self;
add_action('init', [$instance, 'registerPostType']);
add_action('add_meta_boxes', [$instance, 'registerMetaboxes']);
// Do something else related to "Car" post type
}
public function registerPostType()
{
register_post_type( 'car', [
'label' => 'Cars',
]);
}
public function registerMetaBoxes()
{
// Color metabox
add_meta_box(
'car-color-metabox',
__('Color', 'my-plugin'),
[$this, 'colorMetabox'],
'car'
);
}
public function colorMetabox()
{
echo 'Foo';
}
}
```
This way we have a namespace for our CPTs, and an object where we can manage it's properties, such as registering the post type, adding or removing metaboxes, etc.
If we are accepting insertion of "Cars" from the frontend, we would use the [REST API](https://developer.wordpress.org/rest-api/) to receive the POST request and handle it in a [REST Controller Class](https://developer.wordpress.org/rest-api/extending-the-rest-api/controller-classes/), but that is out of the scope of this answer. |

WordPress codex [recommends](https://codex.wordpress.org/Post_Types#A_word_about_custom_post_types_as_a_plugin) that we create Custom Post Types (CPTs) in a plugin. Following that recommendation, I will write my answer using modern PHP, which is not meant for a distributed plugin, but rather for own projects where you have control over the PHP version running.
In the example code bellow, I will use raw examples just to give an idea of the architecture behind the creation of CPTs in a OOP manner, but in a real project, "my-plugin" would be something like "my-project", and the creation of CPTs would be a sort of module of that plugin.
**my-plugin/my-plugin.php**
```
<?php
/**
* Plugin name: My Custom Post Types
*/
namespace MyPlugin;
use MyPlugin/CPT/Car;
// ... Composer autoload or similar here
Car::register();
```
**my-plugin/CPT/Car.php**
```
<?php
namespace MyPlugin\CPT;
/**
* Class Car
*
* Handles the creation of a "Car" custom post type
*/
class Car
{
public static function register()
{
$instance = new self;
add_action('init', [$instance, 'registerPostType']);
add_action('add_meta_boxes', [$instance, 'registerMetaboxes']);
// Do something else related to "Car" post type
}
public function registerPostType()
{
register_post_type( 'car', [
'label' => 'Cars',
]);
}
public function registerMetaBoxes()
{
// Color metabox
add_meta_box(
'car-color-metabox',
__('Color', 'my-plugin'),
[$this, 'colorMetabox'],
'car'
);
}
public function colorMetabox()
{
echo 'Foo';
}
}
```
This way we have a namespace for our CPTs, and an object where we can manage it's properties, such as registering the post type, adding or removing metaboxes, etc.
If we are accepting insertion of "Cars" from the frontend, we would use the [REST API](https://developer.wordpress.org/rest-api/) to receive the POST request and handle it in a [REST Controller Class](https://developer.wordpress.org/rest-api/extending-the-rest-api/controller-classes/), but that is out of the scope of this answer. |

function my_mimes($all)
{
$all['zip'] = 'application/zip';

```
But how to assign multiple file types to 1 extension?
For example, `zip` extension might have `application/zip` mime and also `application/x-zip` (like, coming from `7zip`). This way doesn't work:
```
$all['zip'] = ['application/zip', 'application/x-zip'] ;
``` | Note the stricter mime type check since WP 5.0.1 where the file content and file extension must match. See e.g. this recent [question](https://wordpress.stackexchange.com/q/321804/26350) on the `vtt` file type.
Secondary mime type for a given file extension
----------------------------------------------
Here's a suggestion how to support a secondary mime type for a given file extension. Let's take `.vtt` as an example. The core assumes the mime type of `text/vtt` for that file extension, but the real mime type from `finfo_file()` can sometimes be `text/plain`. The `finfo_file()` seems to be somewhat [buggy](https://bugs.php.net/bug.php?id=75380). We can add a support for it as a secondary mime type with:
```
/**
* Support for 'text/plain' as the secondary mime type of .vtt files,
* in addition to the default 'text/vtt' support.
*/
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
function wpse323750_secondary_mime( $check, $file, $filename, $mimes ) {
if ( empty( $check['ext'] ) && empty( $check['type'] ) ) {
// Adjust to your needs!
$secondary_mime = [ 'vtt' => 'text/plain' ];
// Run another check, but only for our secondary mime and not on core mime types.
remove_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
$check = wp_check_filetype_and_ext( $file, $filename, $secondary_mime );
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
}
return $check;
}
```
Here we use the `wp_check_filetype_and_ext` filter to see if the check failed. In that case we run `wp_check_filetype_and_ext()` again but now only on our secondary mime type, disabling our filter callback in the meanwhile to avoid an infinite loop.
Multiple mime types for a given file extension
----------------------------------------------
If we need to support more than two mime types for the `.vtt` files, then we can expand the above snippet with:
```
/**
* Demo: Support for 'text/foo' and 'text/bar' mime types of .vtt files,
* in addition to the default 'text/vtt' support.
*/
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
function wpse323750_multi_mimes( $check, $file, $filename, $mimes ) {
if ( empty( $check['ext'] ) && empty( $check['type'] ) ) {
// Adjust to your needs!
$multi_mimes = [ [ 'vtt' => 'text/foo' ], [ 'vtt' => 'text/bar' ] ];
// Run new checks for our custom mime types and not on core mime types.
foreach( $multi_mimes as $mime ) {
remove_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
$check = wp_check_filetype_and_ext( $file, $filename, $mime );
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
if ( ! empty( $check['ext'] ) || ! empty( $check['type'] ) ) {
return $check;
}
}
}
return $check;
}
```
I hope you can test it further and adjust it to your needs. |
323,760 | <p>I am able to create a new post but I get a generic error message <code>Publishing failed</code> if I try to publish it. Same thing if I try to edit it (or any other post).
If I try to delete the post using the <code>Move to trash</code> button, I get another error: <code>The response is not a valid JSON response.</code></p>
<p>The issue only happens in the new Gutenberg interface (<code>wp-admin/post.php</code>) I am able to publish or remove the post using the "quick edit" functions on the posts list view (<code>wp-admin/edit.php</code>)
The problem occurs with all users and for all post types (I tried with posts and pages). Deactivating all plugins and visiting the permalinks page did not solve the issue.</p>

| I am able to create a new post but I get a generic error message `Publishing failed` if I try to publish it. Same thing if I try to edit it (or any other post).
If I try to delete the post using the `Move to trash` button, I get another error: `The response is not a valid JSON response.`
The issue only happens in the new Gutenberg interface (`wp-admin/post.php`) I am able to publish or remove the post using the "quick edit" functions on the posts list view (`wp-admin/edit.php`)
The problem occurs with all users and for all post types (I tried with posts and pages). Deactivating all plugins and visiting the permalinks page did not solve the issue. | Note the stricter mime type check since WP 5.0.1 where the file content and file extension must match. See e.g. this recent [question](https://wordpress.stackexchange.com/q/321804/26350) on the `vtt` file type.
Secondary mime type for a given file extension
----------------------------------------------
Here's a suggestion how to support a secondary mime type for a given file extension. Let's take `.vtt` as an example. The core assumes the mime type of `text/vtt` for that file extension, but the real mime type from `finfo_file()` can sometimes be `text/plain`. The `finfo_file()` seems to be somewhat [buggy](https://bugs.php.net/bug.php?id=75380). We can add a support for it as a secondary mime type with:
```
/**
* Support for 'text/plain' as the secondary mime type of .vtt files,
* in addition to the default 'text/vtt' support.
*/
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
function wpse323750_secondary_mime( $check, $file, $filename, $mimes ) {
if ( empty( $check['ext'] ) && empty( $check['type'] ) ) {
// Adjust to your needs!
$secondary_mime = [ 'vtt' => 'text/plain' ];
// Run another check, but only for our secondary mime and not on core mime types.
remove_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
$check = wp_check_filetype_and_ext( $file, $filename, $secondary_mime );
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_secondary_mime', 99, 4 );
}
return $check;
}
```
Here we use the `wp_check_filetype_and_ext` filter to see if the check failed. In that case we run `wp_check_filetype_and_ext()` again but now only on our secondary mime type, disabling our filter callback in the meanwhile to avoid an infinite loop.
Multiple mime types for a given file extension
----------------------------------------------
If we need to support more than two mime types for the `.vtt` files, then we can expand the above snippet with:
```
/**
* Demo: Support for 'text/foo' and 'text/bar' mime types of .vtt files,
* in addition to the default 'text/vtt' support.
*/
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
function wpse323750_multi_mimes( $check, $file, $filename, $mimes ) {
if ( empty( $check['ext'] ) && empty( $check['type'] ) ) {
// Adjust to your needs!
$multi_mimes = [ [ 'vtt' => 'text/foo' ], [ 'vtt' => 'text/bar' ] ];
// Run new checks for our custom mime types and not on core mime types.
foreach( $multi_mimes as $mime ) {
remove_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
$check = wp_check_filetype_and_ext( $file, $filename, $mime );
add_filter( 'wp_check_filetype_and_ext', 'wpse323750_multi_mimes', 99, 4 );
if ( ! empty( $check['ext'] ) || ! empty( $check['type'] ) ) {
return $check;
}
}
}
return $check;
}
```
I hope you can test it further and adjust it to your needs. |

323,932 | <p>I'm using a theme for my WordPress which uses 'Raleway' and it requests (13 requests in gtmetrix waterfall) it from Google fonts API. I want to keep using the font. However, I'm trying to reduce the number of requests and the size of my page. Can I include/integrate the fonts on my website so the browser won't have to execute any external requests?
many thanks </p>

Chrome developer tools show the same results. What could cause this problem? | You have "www.wisconsinwetlands.org" URLs redirecting to insecure "<http://wisconsinwetlands.org>".
The cases you have used these is in the images on the page. Every image that is set as "<https://www>." redirects to the insecure version.
