How to use post_column_taxonomy_links filter in WordPress

post_column_taxonomy_links filter

Filters the links in the $taxonomy column of edit.php.

To use the post_column_taxonomy_links 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.

We at WePlugins 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_post_column_taxonomy_links_defaults which takes 3 parameters and we registered using add_filter. The first parameter post_column_taxonomy_links is the name of the hook, the second parameter weplugins_modify_post_column_taxonomy_links_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 post_column_taxonomy_links filter.

Parameters

Below are the 3 parameters required to use this hook.

• $term_links : (string[]) Array of term editing links.
• $taxonomy : (string) Taxonomy name.
• $terms : (WP_Term[]) Array of term objects appearing in the post row.

Live Example

Example 1: Basic Usage

This example shows how to use the post_column_taxonomy_links filter to modify term links.

    function weplugins_modify_post_column_taxonomy_links_defaults($term_links, $taxonomy, $terms) { 
        // Update the $term_links variable according to your website requirements and return this variable.
        // You can modify the $term_links variable conditionally too if you want.
        return $term_links; 
    }
    // add the filter
    add_filter("post_column_taxonomy_links", "weplugins_modify_post_column_taxonomy_links_defaults", 10, 3);
    

Example 2: Conditional Modification

Here, the term links are modified conditionally based on the taxonomy.

    function weplugins_modify_post_column_taxonomy_links_conditionally($term_links, $taxonomy, $terms) { 
        if ($taxonomy == 'category') {
            // Modify $term_links for categories
        } elseif ($taxonomy == 'post_tag') {
            // Modify $term_links for tags
        }
        return $term_links; 
    }
    // add the filter
    add_filter("post_column_taxonomy_links", "weplugins_modify_post_column_taxonomy_links_conditionally", 10, 3);
    

Example 3: Removing a Hook

To remove a hook callback, use the example below.

    // remove the filter
    remove_filter("post_column_taxonomy_links", "weplugins_modify_post_column_taxonomy_links_defaults", 10, 3);
    

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