I am using this code in Function.php in my wordpress theme , I want to set a member who access by password can access password protected page for 3 time . by using this a member can visit 1 time a page ,
add_action( 'wp', 'post_pw_sess_expire' );
function post_pw_sess_expire() {
if ( isset( $_COOKIE['wp-postpass_' . COOKIEHASH] ) )
// Setting a time of 0 in setcookie() forces the cookie to expire with the session
setcookie('wp-postpass_' . COOKIEHASH, '', 0, COOKIEPATH);
}
