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 );

Usage

$bool = user_can( $user, $capability, $args );

Parameters

$user

( int|WP_User ) required – User ID or object.

$capability

( string ) required – Capability name.

$args

( mixed ) optional –

Returns

bool Whether the user has the given capability.
