How to use image_sideload_extensions filter in WordPress

You know, as a WordPress developer, hooks are like magic spells that can transform your website. Today, let’s dive into the image_sideload_extensions filter. This filter is perfect when you want to control the image file extensions allowed for sideloading. Trust me, you’ll want to keep this one in your toolbox!

Example 1: Basic Usage of image_sideload_extensions

Here’s a simple way to use the image_sideload_extensions filter. This function modifies the allowed extensions according to your needs.

    function weplugins_modify_image_sideload_extensions_defaults($allowed_extensions, $file) { 
        // Update the $allowed_extensions variable as required
        return $allowed_extensions; 
    }
    // add the filter
    add_filter("image_sideload_extensions", "weplugins_modify_image_sideload_extensions_defaults", 10, 2);
    

Example 2: Conditional Extension Modification

Sometimes, you might want to change the extensions only for specific conditions. Here’s how you can do that.

    function weplugins_conditional_image_extensions($allowed_extensions, $file) {
        if (strpos($file, 'example.com') !== false) {
            // Add custom logic here
        }
        return $allowed_extensions;
    }
    add_filter("image_sideload_extensions", "weplugins_conditional_image_extensions", 10, 2);
    

Example 3: Removing the Filter

If you ever need to remove your hook, no worries! You can easily do that with remove_filter.

    remove_filter("image_sideload_extensions", "weplugins_modify_image_sideload_extensions_defaults", 10, 2);
    

Remember, always use the same callback function name, priority, and number of arguments when removing a hook.
