How to use link_title filter in WordPress

link_title filter

Filters the OPML outline link title text.

To use the link_title 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_link_title_defaults which takes 1 parameter and we registered it using add_filter. The first parameter link_title is the name of the hook, the second parameter weplugins_modify_link_title_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 the link_title filter.

Parameters

Below the 1 parameter is required to use this hook.

• $title : (string) The OPML outline title text.

Live Examples

Example 1: Basic Usage

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

    function weplugins_modify_link_title_defaults($title) { 
        // Update the $title variable according to your website requirements and return this variable. 
        // You can modify the $title variable conditionally too if you want.
        return $title; 
    }
    // add the filter
    add_filter("link_title", "weplugins_modify_link_title_defaults", 10, 1);
    

Example 2: Removing the Hook Callback

To remove a hook callback, use the example below.

    remove_filter("link_title", "weplugins_modify_link_title_defaults", 10, 1);
    

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

Example 3: Conditional Title Modification

Here’s how to conditionally modify the title based on certain criteria.

    function weplugins_modify_link_title_conditionally($title) {
        if (strpos($title, 'WordPress') !== false) {
            $title .= " - The Best CMS";
        }
        return $title;
    }
    // add the filter
    add_filter("link_title", "weplugins_modify_link_title_conditionally", 10, 1);
