user_can( int|WP_User $user, string $capability, mixed $args ): bool

Returns whether a particular user has the specified capability.


This function also accepts an ID of an object to check against if the capability is a meta capability. Meta capabilities such as edit_post and edit_user are capabilities used by the map_meta_cap() function to map to primitive capabilities that a user or role has, such as edit_posts and edit_others_posts.

Example usage:

user_can( $user->ID, 'edit_posts' );
user_can( $user->ID, 'edit_post', $post->ID );
user_can( $user->ID, 'edit_post_meta', $post->ID, $meta_key );


User ID or object.
Capability name.
Optional further parameters, typically starting with an object ID.


bool Whether the user has the given capability.


function user_can( $user, $capability, ...$args ) {
	if ( ! is_object( $user ) ) {
		$user = get_userdata( $user );

	if ( empty( $user ) ) {
		// User is logged out, create anonymous user object.
		$user = new WP_User( 0 );
		$user->init( new stdClass() );

	return $user->has_cap( $capability, ...$args );


5.3.0Formalized the existing and already documented ...$args parameter by adding it to the function signature.
