wp_logout_url($redirect)不会注销和重定向()

Question

即使我从wp文档那里得到了代码

<a href="<?php echo wp_logout_url( get_permalink() ); ?>" title="Logout">Logout</a>

这是用户单击它时的输出：

作为URL，类似于：

http://website.com/pedidos/wp-login.php?action=logout&redirect_to=http%3A%2F%2Fwebsite.com%2Fpedidos%2F&_wpnonce=db999bfbcb

-编辑-

function remove_admin_bar() {
    global $wp_admin_bar;
    if (is_user_logged_in()) {
        if (!current_user_can('administrator') && !is_admin()) {
          show_admin_bar(false);
/* LINE 226*/         echo '<style>#background{top:-28px}</style>';
        }

    }
}

Answer 1

你不应该直接从你的functions.php中回传任何东西。这样做将防止重定向。

删除第226行，你就可以走了。您可能希望用更好的编码(甚至插件)替换整个remove_admin_bar。
