In this example we will discuss about server side custom search in datatable. Datatable provides default searching functionality but there you can search on only visible values searching. like in your debatable you show only "user_name" and "email" then you only able to search on those two fields values.
So, Here we will see how to custom search in datatable in laravel, if you want to filter hidden data from database then you need to add datatable custom search or laravel datatable custom filter.
Step 1 : Create Route for Server Side Custom Search in Datatable
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\UserController;
Route::resource('users', UserController::class);
Route::get('getusers', [UserController::class, 'getUsers'])->name('getusers');Read Also : Laravel 8 Export Buttons In Datatables Example
Step 2 : Add Code in Controller
Now, we need to add below code in UserController.
public function getUsers(Request $request, User $user)
{
$input = \Arr::except($request->all(),array('_token', '_method'));
$data = User::where('is_active', '1');
if(isset($input['username'])) {
$data = $data->where('username', 'like', '%'.$input['username'].'%');
}
if(isset($input['country'])) {
$data = $data->where('country', $input['country']);
}
$data = $data->get();
return \DataTables::of($data)
->addColumn('Actions', function($data) {
return '<button type="button" data-id="'.$data->id.'" data-toggle="modal" data-
target="#DeleteUserModal" class="btn btn-danger btn-sm"
id="getDeleteId">Delete</button>';
})
->rawColumns(['Actions'])
->make(true);
}
