How to search by columns union in datatable?

i need to search by user firstname and lastname where are merge to one. Im working with laravel 5.1 and http://datatables.yajrabox.com/.

Here is me code of backend query:

$orders = Order::select([
'orders.created_at',
'users.firstname AS user_firstname',
'users.lastname AS user_lastname'
])
->join('users', 'users.id', '=', 'orders.user_id')
->where('orders.client_id', \Auth::user()->client_id)
->where('orders.status', 'finished');


And return:

return Datatables::of($orders)
->addColumn('user', function ($user) {
return $user->user_firstname.' '.$user->auser_lastname;
})
->addColumn('action', function ($order) {
return '<div class="btn-group" style="min-width: 76px;">
<a href="'.url('history/order/edit/'.$order->id).'" class="btn btn-default"><i class="fa fa-edit"></i></a>
<a href="'.url('history/order/delete/'.$order->id).'" class="btn btn-default" onClick="return confirm(\'Are you sure?\');"><i class="fa fa-times"></i></a>
</div>';
})
->removeColumn('user_firstname')
->removeColumn('user_lastname')
->make(true);


I merge user column to one with user_firstname and user_lastname.

When im searchng in datatable i need to search by this column - USER. Query to to be like this:

SELECT
`orders`.`created_at`,
`users`.`firstname` AS `agent_firstname`,
`users`.`lastname` AS `agent_lastname`,
FROM
`orders`
INNER JOIN `users` ON `users`.`id` = `orders`.`user_id`
WHERE
`orders`.`client_id` = '3'
AND `orders`.`status` = 'finished'
AND (
LOWER(`orders`.`created_at`) LIKE '%search_word%'
OR LOWER(`users`.`firstname`) LIKE '%search_word%'
OR LOWER(`users`.`lastname`) LIKE '%search_word%'
)
ORDER BY
`orders`.`created_at` DESC
LIMIT 10 OFFSET 0


Here is my datatable JS:

// Data tables
var oTable = $('#orders-data').dataTable({
"processing": true,
"serverSide": true,
"ajax": '/history/orders',
"columns": [
{ data: 'created_at', name: 'orders.created_at' },
{ data: 'user', name: 'user' },
{ data: 'action', name: 'action', orderable: false, searchable: false }
],
});


If I change line { data: 'user', name: 'user' } in JS to { data: 'user', name: 'users.firstaname' } than searching only in users.firstname column, But i need search in users.lastname too.

How to do that?

Answer

problem is solved! Here is my code:

$orders = Order::select([
            'orders.created_at',
            \DB::raw("CONCAT(users.firstname,' ',users.lastname) as user")
        ])
        ->join('users', 'users.id', '=', 'orders.user_id')
        ->where('orders.client_id', \Auth::user()->client_id)
        ->where('orders.status', 'finished');

function return:

return Datatables::of($orders)
            ->filterColumn('user', function($query, $keyword) {
                $query->whereRaw("CONCAT(users.firstname,' ',users.lastname) like ?", ["%{$keyword}%"]);
            })
            ->addColumn('action', function ($order) {
                return '<div class="btn-group" style="min-width: 76px;">
                            <a href="'.url('history/order/edit/'.$order->id).'" class="btn btn-default"><i class="fa fa-edit"></i></a>
                            <a href="'.url('history/order/delete/'.$order->id).'" class="btn btn-default" onClick="return confirm(\'Are you sure?\');"><i class="fa fa-times"></i></a>
                        </div>';
            })
            ->removeColumn('user_firstname')
            ->removeColumn('user_lastname')
            ->make(true);

Maybe it helps for others!
