How to use load_image_to_edit filter in WordPress

WordPress hooks are a fantastic way to modify or extend WordPress without altering the core code. If you’re diving into WordPress development, understanding hooks is crucial. One such hook is the load_image_to_edit filter, which allows you to filter the current image being loaded for editing. Let’s explore how you can use this hook effectively in your projects.

To use the load_image_to_edit filter, first, you need to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin. At WePlugins, we always recommend creating a custom WordPress Plugin while using hooks to ensure nothing breaks when you update your WordPress Theme in the future.

In the example below, we’ve defined a function modify_load_image_to_edit_defaults that takes three parameters, and we’ve registered it using add_filter. The parameters are the name of the hook, the name of the function to be called, the priority of the hook, and the number of arguments to be passed to the registered function. Sometimes, you might need to remove a registered hook, and you can do so using remove_filter to remove the load_image_to_edit filter.

Parameters

Below are the 3 parameters required to use this hook:

• $image: (resource|GdImage) Current image.
• $attachment_id: (int) Attachment ID.
• $size: (string|int[]) Requested image size. Can be any registered image size name or an array of width and height values in pixels (in that order).

Example 1: Basic Usage

This example shows how to apply the load_image_to_edit filter.

    apply_filters( 'load_image_to_edit', resource|GdImage $image, int $attachment_id, string|int[] $size );
    

Example 2: Modify Image on Load

Below is an example of how you can use this hook to modify the image.

    function weplugins_modify_load_image_to_edit_defaults($image, $attachment_id, $size) { 
        // Update the $image variable according to your website requirements and return this variable.
        return $image; 
    }
    // add the filter
    add_filter( "load_image_to_edit", "weplugins_modify_load_image_to_edit_defaults", 10, 3 );
    

Example 3: Removing a Hook

To remove a hook callback, use the example below.

    remove_filter( "load_image_to_edit", "weplugins_modify_load_image_to_edit_defaults", 10, 3 );
    

Please ensure you provide the same callback function name, priority, and number of arguments when removing the hook callback.
