如果用户(admin)在wordpress站点中处于非活动状态15分钟,我希望会话到期,

任何人都可以告诉我什么是wordpress中的默认会话到期时间？以及如何更改默认过期时间.

只需在主题的functions.php中添加此代码:

add_filter('auth_cookie_expiration', 'my_expiration_filter', 99, 3);
function my_expiration_filter($seconds, $user_id, $remember){

    //if "remember me" is checked;
    if ( $remember ) {
        //WP defaults to 2 weeks;
        $expiration = 14*24*60*60; //UPDATE HERE;
    } else {
        //WP defaults to 48 hrs/2 days;
        $expiration = 2*24*60*60; //UPDATE HERE;
    }

    //http://en.wikipedia.org/wiki/Year_2038_problem
    if ( PHP_INT_MAX - time() < $expiration ) {
        //Fix to a little bit earlier!
        $expiration =  PHP_INT_MAX - time() - 5;
    }

    return $expiration;
}
