WooCommerce 教程：隐藏非管理员的 WP-admin

redmaomail 2024-07-24 17:22 阅读数 86 #WooCommerce

我今天正在玩自己的结帐设计和 UX，而在测试时，我意识到新客户可以在购买后访问 WP 管理黑色条。所以 – 我说 – 容易的任务！

但是经过 20 分钟的现实（以为是需要 1 分钟），我终于找到了这个问题。和往常一样，这个博客自带的解决方案 – 随意使用这个修复在您自己的 WooSite

1. 隐藏 WP 管理员：理论

WordPress 为我们提供了一个名为 “ show_admin_bar ” 的过滤器。容易的愚蠢 – 将其设置为 false，管理员栏已经消失：


// 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. 隐藏 WP 管理员：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.

3. 隐藏非管理员的 WP 管理栏：WooCommerce PHP Snippet

function bbloomer_hide_admin_bar_if_non_admin( $show ) {
	if ( ! current_user_can( 'administrator' ) ) $show = false;
	return $show;
}

add_filter( 'show_admin_bar', 'bbloomer_hide_admin_bar_if_non_admin', 20, 1 );

// please note the priority = '20' to make sure we run the filter after Woo's one
