How to use load_image_to_edit_filesystempath filter in WordPress

load_image_to_edit_filesystempath filter

The filter is evaluated for all image sizes except ‘full’.

To use load_image_to_edit_filesystempath 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_load_image_to_edit_filesystempath_defaults which takes 3 parameters and we registered using add_filter. The first parameter load_image_to_edit_filesystempath is the name of the hook, The second parameter weplugins_modify_load_image_to_edit_filesystempath_defaults is the name of the function that 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 load_image_to_edit_filesystempath filter.

Parameters

Below are the 3 parameters required to use this hook.

• $path : (string) Path to the 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).

Live Example

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

Example 1: Basic Usage

This example demonstrates a simple use case where we modify the $path variable conditionally.

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

Example 2: Conditional Path Modification

In this example, we modify the $path variable only if the attachment ID matches a specific value.

        function weplugins_modify_load_image_to_edit_filesystempath_conditionally($path, $attachment_id, $size) { 
            if ($attachment_id === 123) {
                $path = '/new/path/to/image.jpg';
            }
            return $path; 
        }
        // add the filter
        add_filter( "load_image_to_edit_filesystempath", "weplugins_modify_load_image_to_edit_filesystempath_conditionally", 10, 3 );
    

Example 3: Removing a Hook

To remove a hook callback, use the example below.

        // remove the filter
        remove_filter( "load_image_to_edit_filesystempath", "weplugins_modify_load_image_to_edit_filesystempath_defaults", 10, 3 );
    

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