开发笔记:Laravel5.1与Laypage结合进行分页

Route::match(array(\'get\',\'post\'),\'/orm\',\'StuController@orm\');

php
namespace App\\Http\\Controllers;
use Illuminate\\Http\\Request;
use App\\Http\\Requests;
use App\\User; //user表的模型
use App\\Phone; //phone表的模型
class StuController extends Controller
{
/*

private $current_page; //私有属性 当前页
private $page_size = 5; //私有属性 每页条数
public function __construct(Request $request) {
$this->current_page = $request->input(\'current_page\', 1);
}
public function orm(Request $request)
{
$search_text = $request->input(\'search_text\',\'\');
$pay_type = intval($request->input(\'pay_type\',6));
if($search_text == \'\')
{
$count = User::join(\'phone\',\'phone.user_id\',\'=\',\'user.user_id\',\'left\')->count();
