我想创造一个submenu page 在\'Users\' 与“所有用户”页面类似，但for listing users of specific roles only. 让我们调用此子菜单页\'Customer\'.
到目前为止，我设法创建了一个具有自己列的列，但仍有一些内容我没有设法修改to make the contents more relevant:
以下是我需要做的：我该怎么做change the page title 要反映子菜单名称，在本例中为“Customer”filter links above the list to show ONLY \'All\', \'Subscriber\', & \'Pending\'? （b） 还有\'Change role to..\' dropdown menu?\'All\' to direct to the \'Customer\' page （哪个是自定义用户页）\'Customer\' submenu link to hilite 是否指示当前查看的页面NOTE:
默认\'All Users\' 因此，页面应为the
opposite 本页的filter links.
以下是我创建上述页面的大致方式：
/* Create new user submenu with custom parameter in slug */
add_action(\'admin_menu\', \'my_custom_user_submenu\');
function my_custom_user_submenu() {
add_users_page(
\'Customer\',
\'Customer\',
list_users,
\'users.php?user=custom\'
);
}
/* Filter users according to the users list page */
add_action(\'pre_user_query\',\'my_user_customer_list\');
function my_user_customer_list($user_search) {
$user = $_GET[\'custom\'];
$role = $_GET[\'role\'];
if ( $user == \'custom\' OR $role == \'subscriber\' OR $role == \'pending\' ) {
global $wpdb;
/* For Customers Page:
* Get only \'Subscriber\' & \'Pending\' users
* */
$user_search->query_where =
str_replace(\'WHERE 1=1\',
"WHERE 1=1 AND {$wpdb->users}.ID IN (
SELECT {$wpdb->usermeta}.user_id FROM $wpdb->usermeta
WHERE {$wpdb->usermeta}.meta_key = \'{$wpdb->prefix}user_level\'
AND {$wpdb->usermeta}.meta_value = 0)",
$user_search->query_where
);
} else {
global $wpdb;
/* For User Admin Page:
* Get all apart from \'Subscriber\' & \'Pending\' users
* */
$user_search->query_where =
str_replace(\'WHERE 1=1\',
"WHERE 1=1 AND {$wpdb->users}.ID IN (
SELECT {$wpdb->usermeta}.user_id FROM $wpdb->usermeta
WHERE {$wpdb->usermeta}.meta_key = \'{$wpdb->prefix}user_level\'
AND {$wpdb->usermeta}.meta_value >= 1)",
$user_search->query_where
);
}
}

下面是我如何修改页面的。对于submenu highlighting, 然而，我还没有弄明白，所以我resort to jQuery.
代码如下：
/* - Set user filter links according to users pages
* - Set Role Change dropdown menu
* */
function custom_user_filter_links( $views ) {
global $wp_roles; // For Role Change dropdown menu
$amt = count_users();
$amtCustom = $amt[\'avail_roles\'][\'subscriber\'] + $amt[\'avail_roles\'][\'pending\']; // Count custom users
if ( $_GET[\'user\'] == \'custom\' || $_GET[\'role\'] == \'subscriber\' || $_GET[\'role\'] == \'pending\' ) {
/* For Customers Page: */
/* Modify url & users count for the \'All\' link */
$all = preg_replace( \'/(.*\\.php)(.*\\().*(\\).*)/\', \'$1?user=custom${2}\'.$amtCustom.\'$3\', $views[\'all\'] );
/* Show only \'Subscriber\' & \'Pending\' user links */
$arr = array();
$arr[\'all\'] = $all;
if ($views[\'subscriber\'])
$arr[\'subscriber\'] = $views[\'subscriber\'];
if ($views[\'pending\'])
$arr[\'pending\'] = $views[\'pending\'];
$views = $arr;
/* Modify Role Change dropdown menu */
$arr = array();
$arr[\'subscriber\'] = $wp_roles->roles[\'subscriber\'];
$arr[\'pending\'] = $wp_roles->roles[\'pending\'];
$wp_roles->roles = $arr;
} else {
/* For User Admin Page: */
/* Modify users count for the \'All\' link*/
$views[\'all\'] = preg_replace( \'/(.*\\().*(\\).*)/\', \'${1}\'.($amt[\'total_users\'] - $amtCustom).\'$2\', $views[\'all\'] );
/* Remove \'Subscriber\' & \'Pending\' user links */
unset($views[\'subscriber\']);
unset($views[\'pending\']);
/* Modify Role Change dropdown menu */
unset ( $wp_roles->roles[\'subscriber\'] );
unset ( $wp_roles->roles[\'pending\'] );
}
return $views;
}
add_filter( \'views_users\', \'custom_user_filter_links\' );
/* - Highlight custom submenu
* - Change titles of custom Users Manage & Edit pages
* */
function submenu_hilite_n_rename_title() {
global $current_screen;
// If not in specified pages than discontinue
if( !($current_screen->base == \'users\' || $current_screen->base == \'user-edit\') )
return;
global $title;
if ($current_screen->base == \'user-edit\') {
/* For Edit User page */
$user = get_user_by(\'id\', $_GET[\'user_id\']);
$role = $user->roles[0];
$title = \'Edit Customer\'; /* Change page title */
} else {
/* For Manage Users page */
$role = $_GET[\'role\'];
$title = \'Customers\'; /* Change page title */
}
switch (true) {
case $_GET[\'user\'] == \'custom\' :
case $role == \'subscriber\' :
case $role == \'pending\' :
?>
<script type="text/javascript">
jQuery(document).ready( function($) {
var reference = $(\'a[href$="user=custom"]\').parent();
// Highlight custom submenu
reference.addClass(\'current\');
// Remove highlight from default menu
reference.parent().find(\'li:first\').removeClass(\'current\');
});
</script>
<?php
break;
}
}
add_action(\'admin_head\', submenu_hilite_n_rename_title);
