我没有什么小问题。如果我提交了用于登录的用户凭据，无论登录详细信息是否正确，页面都会转到“提交时禁止”按钮。我如何解决这个问题

提交后此处为禁止页面。

public function loginForm(){
    if(!session_id()){
        @session_start();
    }
    global $post;
    $redirect_page = get_option(\'redirect_page\');
    $redirect_page_url = get_option(\'redirect_page_url\');
    $logout_redirect_page = get_option(\'logout_redirect_page\');
    $link_in_username = get_option(\'link_in_username\');
    $default_login_form_hooks = get_option(\'default_login_form_hooks\');

    if($redirect_page_url){
        $redirect = $redirect_page_url;
    } else {
        if($redirect_page){
            $redirect = get_permalink($redirect_page);
        } else {
            $redirect = $this->curPageURL();
        }
    }

    if($logout_redirect_page){
        $logout_redirect_page = get_permalink($logout_redirect_page);
    } else {
        $logout_redirect_page = $this->curPageURL();
    }
    $this->load_script();
    $this->error_message();
    if(!is_user_logged_in()){
    ?>
