对于任何正在寻找解决方案的人。我男朋友和我用下面的剧本解决了这个问题。只需粘贴到函数中即可。任何woocommerce设置的php文件。

/** Log in redirect to previous page by portalpacific.net **/
// start global session for saving the referer url
function start_session() {
    if(!session_id()) {
        session_start();
    }
}
add_action(\'init\', \'start_session\', 1);

// get the referer url and save it to the session
function redirect_url() {
    if (! is_user_logged_in()) {
        $_SESSION[\'referer_url\'] = wp_get_referer();
    } else {
        session_destroy();
    }
}
add_action( \'template_redirect\', \'redirect_url\' );

//login redirect to referer url
function login_redirect() {
    if (isset($_SESSION[\'referer_url\'])) {
        wp_redirect($_SESSION[\'referer_url\']);
    } else {
        wp_redirect(home_url());
    }
}
add_filter(\'woocommerce_login_redirect\', \'login_redirect\', 1100, 2);

/** end here */
