嗨,当我正在搜索订单时,我无法将订单分页(每页5个订单)..

我还记录了自己,以向您展示我目前遇到的问题:

这是我正在使用的代码:

OrdersController.php:

public function post_search()
{
    $keyword=Input::get('keyword');

    if(empty($keyword))
        return Redirect::route('user.orders.index')->with('error_search', 'Er was geen zoekterm ingevuld, probeer het nog eens.');

    //$orders = Order::with('client')->get(); 
    //$orders= new stdClass;
    //$orders->foo=Order::search($keyword)->paginate(5);
    $orders=Order::search($keyword);
    $msg="";

    if (!count($orders)) {
        $msg="There were no orders found.";
    }else{
        $msg="There were orders found";
    }

    $orders = Paginator::make($orders, count($orders), 5);

    foreach( $orders as &$order){

        //we initialize ordertask
        $order->ordertask = Ordertask::where('id_order', '=', $order->id)->get();

    }

    return View::make('user.orders.index', compact('orders', 'msg'));

}

Order.php:

public static function search($keyword){

DB::connection()->getPdo()->quote($keyword);

    $result = DB::Select(DB::raw('SELECT orders.*, tasks_x.task_all
        FROM orders LEFT JOIN (SELECT GROUP_CONCAT(tasks.task_name SEPARATOR ",")
         AS task_all, ordertasks.id_order 
            FROM tasks JOIN ordertasks 
            on ordertasks.id_task = tasks.id GROUP BY ordertasks.id_order) as tasks_x
            ON tasks_x.id_order = orders.id WHERE orders.order_name 
            LIKE "%'.$keyword.'%" OR tasks_x.task_all LIKE "%'.$keyword.'%"'));

    return $result;           
}

我尝试了什么:

我已将表单操作更改为GET和POST,但这不起作用。

有人可以帮助我吗?

您无法使用laravel paginator对原始查询进行分页。您只能对使用查询构建器或Eloquent模型进行的查询进行分页。

您必须手动对查询进行分页(在查询中使用LIMIT),然后使用Paginator :: Make()来显示分页器视图。此外,您必须检索具有不同查询的项目数,因为在结果数组上使用count()将为您提供该页面中的结果数(通常,页面大小,最后一页除外)

其他选项是从原始查询更改为使用查询构建器进行的查询,但是laravel并不建议您使用" Group By"官方文件说:

  

注意:目前,Laravel无法有效执行使用groupBy语句的分页操作。如果您需要将groupBy与分页结果集一起使用,建议您手动查询数据库并使用Paginator :: make。

这是我在每个分页搜索中所做的事情:
控制器

$query = new Product();

//dynamic search term
if (Input::has('code')){
    $term = Input::get('code');
    $term = trim($term);
    $term = str_replace(" ", "|", $term);
    $query = $query->whereRaw("itemcode regexp '".$term."'");
if (Input::has('description')){
    $term = Input::get('description');
    $term = trim($term);
    $term = str_replace(" ", "|", $term);
    $query = $query->whereRaw("itemcode regexp '".$term."'");
}
//if there are more search terms, just copy statements above

$products = $query->paginate(50); //get 50 data per page
$products->setPath(''); //in case the page generate '/?' link.
$pagination = $products->appends(array('code' => Input::get('code'),
    'description' => Input::get('description')
    //add more element if you have more search terms
));
//this will append the url with your search terms

return redirect('product')->with('products', $products)->with('pagination', $pagination);
