2. Problem

How to restrict Imagify plugin access to a single user (by id).

3. Solution

We will use a simple function to restrict Imagify access to a single user, in this case, the user will have the ID of 1. You will need to have a basic understanding of PHP to use this function and you will also need to know the ID of the user you want to grant access to.

The Function

 * Filter the user capacity used to operate Imagify.
 * @since  1.0
 * @author Grégory Viguier
 * @param  string $capacity  The user capacity.
 * @param  string $describer Capacity describer. Possible values are 'manage', 'bulk-optimize', 'manual-optimize', and 'auto-optimize'.
 * @return string
add_filter( 'imagify_capacity', 'private_imagify', 10, 2 );
function private_imagify( $capacity, $describer ) {
	if ( 'manage' !== $describer || 'bulk-optimize' !== $describer ) {
		return $capacity;

	$user_id = get_current_user_id();

	if ( 1 !== $user_id ) { // Put your user ID here.
		return 'nope';

	return $capacity;

Simply place this function in your theme functions, create a plugin, or use Code Snippets.


With the help of this plugin, we can restrict users to use a plugin from the admin area.
