How to use ext2type filter in WordPress

So you’re diving into the world of WordPress hooks? Awesome choice! Today, we are going to chat about the ext2type filter. It’s a super handy tool for those of us who love tweaking and customizing WordPress. You’ll want to start by registering this filter using add_filter. You can place this code in your theme’s functions.php file or, to keep things neat and safe from theme updates, in a custom WordPress plugin. At WePlugins, we definitely recommend the plugin route to keep things smooth!

Example 1: Modify Default File Extensions

This example demonstrates how to modify the default file extensions in WordPress using the ext2type filter.

    function weplugins_modify_ext2type_defaults($ext2type) { 
        // Update the $ext2type variable according to your website requirements and return this variable.
        return $ext2type; 
    }
    // Add the filter
    add_filter( "ext2type", "weplugins_modify_ext2type_defaults", 10, 1 );
    

Example 2: Conditional Modification of File Extensions

In this example, we modify the file extensions conditionally based on some criteria.

    function weplugins_conditional_ext2type($ext2type) { 
        // Check some condition and modify $ext2type accordingly
        if (some_condition()) {
            // Change $ext2type
        }
        return $ext2type; 
    }
    // Add the filter
    add_filter( "ext2type", "weplugins_conditional_ext2type", 10, 1 );
    

Example 3: Removing a Filter Hook

Here’s how you can remove a filter hook when it’s no longer needed.

    // Remove the filter
    remove_filter( "ext2type", "weplugins_modify_ext2type_defaults", 10, 1 );
    

Make sure to provide the same callback function name, priority, and number of arguments when removing the hook callback.
