WordPress实现用户注册审核功能

如何通过WordPress过滤器来说实现相关功能？

如图所示：

用户列表界面设置

WordPress用户页面，点击顶部用户类型，通过URL中status参数来过滤，那么添加一个参数为：unapproved 网址参数为：网址/wp-admin/users.php?status=unapproved

添加界面过滤器

add_filter(‘views_users’, ‘corepress_views_users’);

function corepress_views_users($views)
{
global $wpdb;
if (!current_user_can(‘edit_users’)) return $views;

$current = ”;
if (isset($_REQUEST[‘status’]) & $_REQUEST[‘status’] == ‘unapproved’) $current = ‘class=”current”‘;

$meta_key = ‘corepress_approve’;
$users = get_users(array(
‘meta_query’ => array(
array(
‘key’ => $meta_key,
‘value’ => ‘1’,
‘compare’ => ‘=’
)
)
));
$count = count($users);
$views[‘unapproved’] = ” . ‘待审核’ . ‘ （’ . $count . ‘）’;
return $views;
}

这个时候，已经能显示待审核的用户列表了

实现用户查询

通过user_meta，来查询，并返回给前台

add_filter(‘pre_get_users’, ‘filter_users’);

function corepress_filter_users($query)
{
global $pagenow;
if (is_admin() & ‘users.php’ == $pagenow) {
global $wpdb;
if (!isset($_GET[‘orderby’])) {
$query->set(‘orderby’, ‘registered’);
$query->set(‘order’, ‘desc’);
}
if (isset($_REQUEST[‘status’]) && $_REQUEST[‘status’] == ‘unapproved’) {
$query->set(‘meta_query’, array(
array(
‘key’ => ‘corepress_approve’,
‘value’ => ‘1’,
‘compare’ => ‘=’
)
));
}
}
return $query;
}

实现批量修改用户审核状态

添加批量操作表项

add_filter(‘bulk_actions-users’, ‘corepress_add_userlist_approve’);
function corepress_add_userlist_approve($actions)
{
if (current_user_can(‘edit_users’)) {
$actions[‘approve’] = ‘审核用户’;
$actions[‘disapprove’] = ‘设置为未审核’;
}
return $actions;
}

接管批量操作

add_filter(‘handle_bulk_actions-users’, ‘corepress_handle_users’, 10, 3);
function corepress_handle_users($redirect_to, $doaction, $ids)
{
if (!$ids || !current_user_can(‘edit_users’)) return $redirect_to;
if ($doaction == ‘approve’) {
foreach ($ids as $id) {
update_user_meta($id, ‘corepress_approve’, 0);
}
} else if ($doaction == ‘disapprove’) {
foreach ($ids as $id) {
update_user_meta($id, ‘corepress_approve’, 1);
}
}
return $redirect_to;
}

这个时候，一套体系已经完成了，在注册用户的时候，为用户添加额外字段，就能实现审核的功能了。
