The default current_user_can() and user_can() functions are adequate for checking if a user belongs to a role, but I find the function names confusing.\u00a0 Also, those functions check both roles and capabilities, which seems inefficient if one only needs to check the role.<\/p>\n
This function does one thing only: check if a user belongs to a role.<\/p>\n
function myprefix_user_has_role($user, $rolename) {\r\n if ( !is_a($user, 'WP_User') ) {\r\n $user = get_userdata( $user );\r\n }\r\n if ( !$user ) {\r\n return false;\r\n }\r\n\r\n foreach($user->roles as $role) {\r\n if (strtolower($rolename) === strtolower($role) ) {\r\n return true;\r\n }\r\n }\r\n \r\n return false;\r\n}<\/pre>\nA common usage is to check if a user an administrator, so this function works along with the above function to do just that:<\/p>\n
function myprefix_is_admin($user = null) {\r\n if ($user == null) {\r\n $user = get_current_user_id();\r\n }\r\n return myprefix_user_has_role($user, 'administrator');\r\n}<\/pre>\n <\/p>\n","protected":false},"excerpt":{"rendered":"
