Detailed explanation of adding and deleting WordPress backend admin menu separators

The following tutorial column of WordPress will introduce to you how to add and delete the separator in the WordPress backend management menu. I hope it will be helpful to friends in need!

Add and delete the WordPress backend management menu separator

I don’t know if you have noticed the WordPress backend dashboard and comment menu. There is an empty separator, but there is no one under other menus, as shown below:

The delimiter code is located in the menu.php file in the wp-admin directory.

Line 62:

$menu[4] = array( '', 'read', 'separator1', '', 'wp-menu-separator' );

Line 184:

$menu[59] = array( '', 'read', 'separator2', '', 'wp-menu-separator' );

Many years ago, users gave feedback to WP officials to recommend deleting the separator. The official said that the separator is used to distinguish separation. Different management modules are not pre-adopted, but the separator has no style and only a height, so there is really no point in retaining it.

Delete the separator

If you are like me and find this abrupt space distasteful, then here is a tutorial on how to delete this separator. The simplest way is to delete the menu directly. Those two lines of code in the php file will need to be deleted again next time the program is updated, which is quite troublesome. A once-and-for-all method:

Add the following code to the theme function template functions.php.

function zm_remove_menu() {
global $menu;
unset($menu[4]);
unset($menu[59]);
}
add_action('admin_head', 'zm_remove_menu');

If you want to delete other menu items, you can open the menu.php file to view the position number of the corresponding menu item. For example, the media is $menu[10], and add a sentence to the above code like a cat and a tiger:

unset($menu[10]);

Introduced like this.

Attached are other ways to delete the menu and expand it

Add separator

As a theme designer, if you want to add a separator in the theme custom menu part, it will be used as a prompt This is unique to the user's theme. For example, if you add it under the media menu No. 10, you can write:

add_action('admin_menu', function () {
global $menu;
$menu[11] = ['', 'read', '', '', 'wp-menu-separator'];
});

Define the separator style

Want to define this separator style You can write

function zm_separator_style(){
echo&#39;<style type="text/css">.separator {border-bottom: 1px solid #2271b1;}</style>&#39;;
}
add_action(&#39;admin_head&#39;, &#39;zm_separator_style&#39;);

and add it to the theme function template functions.php.

Move the menu position

If you want to customize the menu position, for example, move the article menu below the media menu, you can write:

function zm_move_menu () {
global $menu;
$menu[11] = $menu[5]; // 将编号5的文章菜单移动到编号10的媒体菜单下
unset($menu[5]); // 移除原文章菜单
}
add_action('admin_menu', 'zm_move_menu');

Others can be deduced by analogy.
