WooCommerce 教程：隱藏非管理員的 WP-admin

我今天正在玩自己的結帳設計和 UX，而在測試時，我意識到新客戶可以在購買後訪問 WP 管理黑色條。所以 – 我說 – 容易的任務！

但是經過 20 分鐘的現實（以為是需要 1 分鐘），我終於找到了這個問題。和往常一樣，這個部落格自帶的解決方案 – 隨意使用這個修復在您自己的 WooSite🙂

1. 隱藏 WP 管理員：理論

WordPress 為我們提供了一個名為 “ show_admin_bar ” 的過濾器。容易的愚蠢 – 將其設定為 false，管理員欄已經消失：

 // Disable admin bar for non admins (this would work on a non-Woo site...)  function bbloomer_hide_admin_bar_if( $show ) { 	if ( /* CONDITION */ ) $show = false; 	return $show; }  add_filter( 'show_admin_bar', 'bbloomer_hide_admin_bar_if' );

2. 隱藏 WP 管理員：Woo Reality

After the above snippet wouldn’t work on a Woo install, I did a lot of research. Tried other snippets but nothing. So, I said to myself… what if WooCommerce is ALREADY using that filter and I’m trying to edit the behavior of something that Woo is already modifying?

Well… here’s what I found in woocommerceincludeswc-user-functions.php:

 /**  * Prevent any user who cannot 'edit_posts' (subscribers, customers etc) from seeing the admin bar.  *  */  function wc_disable_admin_bar( $show_admin_bar ) { 	if ( apply_filters( 'woocommerce_disable_admin_bar', get_option( 'woocommerce_lock_down_admin', 'yes' ) === 'yes' ) && ! ( current_user_can( 'edit_posts' ) || current_user_can( 'manage_woocommerce' ) ) ) { 		$show_admin_bar = false; 	}  	return $show_admin_bar; } add_filter( 'show_admin_bar', 'wc_disable_admin_bar', 10, 1 );

See, something is already using the filter “show_admin_bar”, and what matters the most – the priority specified there is “10”.

Basically I was changing the behavior of the WP Admin Bar, but then WooCommerce was re-changing it after my call – in fact without specifying the priority, my filter got a default priority of “10”, too early to expect Woo NOT to re-change such functionality.

If this is not clear, and you’d rather get the fix – well, not to worry, here it is.
