How to use editable_extensions filter in WordPress

Alright, let’s dive into the world of WordPress hooks! If you’re like me, always tinkering with WordPress to make it just right, you’re in the right place. Today, we’re talking about the editable_extensions filter. It’s all about filtering the list of file types you can edit in the plugin file editor. Pretty handy, right?

Example 1: Basic Usage of editable_extensions

Here’s a straightforward example of how you can use the editable_extensions hook. The function weplugins_modify_editable_extensions_defaults is created to modify the default types based on your specific needs.

    function weplugins_modify_editable_extensions_defaults($default_types, $plugin) {
        // Update the $default_types variable according to your website requirements and return this variable. 
        return $default_types; 
    }
    // Add the filter
    add_filter("editable_extensions", "weplugins_modify_editable_extensions_defaults", 10, 2);
    

Example 2: Conditional Modification

Sometimes, you might need to conditionally modify the editable file extensions. Here’s how you can do that.

    function weplugins_modify_editable_extensions_conditionally($default_types, $plugin) {
        // Check some condition, for example, a specific plugin
        if ($plugin === 'specific-plugin/specific-file.php') {
            $default_types[] = 'json'; // Add json extension
        }
        return $default_types;
    }
    // Add the filter
    add_filter("editable_extensions", "weplugins_modify_editable_extensions_conditionally", 10, 2);
    

Example 3: Removing the Hook

If you ever find the need to remove a previously registered hook, here’s a quick guide on how to do it. Just make sure you use the same callback function, priority, and number of arguments.

    // Remove the filter
    remove_filter("editable_extensions", "weplugins_modify_editable_extensions_defaults", 10, 2);
