How to use author_link filter in WordPress

author_link filter

Filters the URL to the author’s page. To use author_link 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 modify_author_link_defaults which takes 3 parameters and we registered using add_filter. The first parameter author_link is the name of the hook, The second parameter modify_author_link_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 author_link filter.

Parameters

• $link: (string) The URL to the author’s page.
• $author_id: (int) The author’s ID.
• $author_nicename: (string) The author’s nice name.

Live Example 1: Basic Usage

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

    add_filter( 'author_link', 'weplugins_modify_author_link', 10, 1 );        
    function weplugins_modify_author_link( $link ) {       
        $link = 'http://example.com/';
        return $link;
    }
    

Live Example 2: Modifying Author Link

Here’s another example to modify the author link with specific parameters.

    function weplugins_modify_author_link_defaults($link, $author_id, $author_nicename) { 
        // Update the $link variable according to your website requirements and return this variable. You can modify the $link variable conditionally too if you want.
        return $link; 
    }
    // add the filter
    add_filter("author_link", "weplugins_modify_author_link_defaults", 10, 3 );
    

Live Example 3: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_filter("author_link", "weplugins_modify_author_link_defaults", 10, 3 );
    

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