How to use manage_taxonomies_for_post_type_columns filter in WordPress

manage_taxonomies_for_post_type_columns filter

The dynamic portion of the hook name, $post_type, refers to the post type slug.

To use manage_taxonomies_for_post_type_columns filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

At WePlugins, we always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_modify_manage_taxonomies_for_post_type_columns_defaults which takes 2 parameters and we registered using add_filter. The first parameter manage_taxonomies_for_post_type_columns is the name of the hook, the second parameter weplugins_modify_manage_taxonomies_for_post_type_columns_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove manage_taxonomies_for_post_type_columns filter.

Parameters

Below are the 2 parameters required to use this hook.

• $taxonomies : (string[]) Array of taxonomy names to show columns for.
• $post_type : (string) The post type.

Live Example

apply_filters( "manage_taxonomies_for_{$post_type}_columns", string[] $taxonomies, string $post_type )

Below is an example of how you can use this hook.

Example 1: Modifying Taxonomies for a Custom Post Type

This example shows how you can modify the taxonomies for a custom post type.

function weplugins_modify_manage_taxonomies_for_post_type_columns_defaults($taxonomies, $post_type) { 
    // Update the $taxonomies variable according to your website requirements and return this variable. You can modify the $taxonomies variable conditionally too if you want.
    return $taxonomies; 
}
// add the filter
add_filter( "manage_taxonomies_for_post_type_columns", "weplugins_modify_manage_taxonomies_for_post_type_columns_defaults", 10, 2 );

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

remove_filter( "manage_taxonomies_for_post_type_columns", "weplugins_modify_manage_taxonomies_for_post_type_columns_defaults", 10, 2 );

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Adding Conditional Logic

This example adds conditional logic to the weplugins_modify_manage_taxonomies_for_post_type_columns_defaults function.

function weplugins_modify_manage_taxonomies_for_post_type_columns_defaults($taxonomies, $post_type) { 
    if ($post_type == 'custom_post_type') {
        // Modify the $taxonomies variable only for a specific post type
    }
    return $taxonomies; 
}
// add the filter
add_filter( "manage_taxonomies_for_post_type_columns", "weplugins_modify_manage_taxonomies_for_post_type_columns_defaults", 10, 2 );
