WordPress后台用户列表添加用户注册时的IP地址方法

我们只需将下面代码添加到当前WordPress模板函数functions.php中即可：

function log_ip($user_id){
	$ip = $_SERVER['REMOTE_ADDR']; 
	update_user_meta($user_id, 'signup_ip', $ip); 
}
add_action('user_register', 'log_ip');
 
// 添加IP地址栏目
function signup_ip($column_headers) {
	$column_headers['signup_ip'] = __('IP地址', 'signup_ip');
	return $column_headers;
}
if ( is_multisite() ) {
	// 多站点支持
	add_filter('wpmu_users_columns', 'signup_ip');
} else {
	// 单站点支持
	add_filter('manage_users_columns', 'signup_ip');
}
 
// 格式化输出内容 
function ripms_columns($value, $column_name, $user_id) {
	if ( $column_name == 'signup_ip' ) {
		$ip = get_user_meta($user_id, 'signup_ip', true);
		if ($ip != ""){
			$ret = '<em>'.__($ip, 'signup_ip').'</em>';
			return $ret;
		} else {
			$ret = '<em>'.__('暂无数据', 'signup_ip').'</em>';
			return $ret;
		}
	}
	return $value;
}
add_action('manage_users_custom_column',  'ripms_columns', 10, 3);

WordPress后台用户列表怎么按用户注册时间排序

//添加用户注册时间列
add_filter( 'manage_users_columns', 'zhuige_manage_users_columns' );
function zhuige_manage_users_columns( $columns ){
    $columns[ 'registered' ] = '注册时间';
    return $columns;
}

//通过 manage_users_custom_column 钩子返回值排序
add_action( 'manage_users_custom_column', 'zhuige_manage_users_custom_column', 10, 3 );
function  zhuige_manage_users_custom_column( $var, $column_name, $user_id ){
    switch( $column_name ) {
        case "registered" :
            return get_user_by('id', $user_id)->data->user_registered;
    }
}

//让添加的“注册时间”可以点击
add_filter( "manage_users_sortable_columns", 'zhuige_manage_users_sortable_columns' );
function zhuige_manage_users_sortable_columns($sortable_columns){
    $sortable_columns['registered'] = 'registered';
    return $sortable_columns;
}
