I've created a form which adds a category of product in a Categories table (for example Sugar Products or Beer), and each user has their own category names.
The Categories table has the columns id
, category_name
, userId
, created_At
, updated_At
.
I've made the validation and every thing is okay. But now I want every user to have a unique category_name. I've created this in phpMyAdmin and made a unique index on (category_name
and userId
).
So my question is this: when completing the form and let us say that you forgot and enter a category twice... this category exist in the database, and eloquent throws me an error. I want just like in the validation when there is error to redirect me to in my case /dash/warehouse and says dude you are trying to enter one category twice ... please consider it again ... or whatever. I am new in laravel and php, sorry for my language but is important to me to know why is this happens and how i solve this. Look at my controller if you need something more i will give it to you.
class ErpController extends Controller{
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
return view('pages.erp.dash');
}
public function getWarehouse()
{
$welcome = Auth::user()->fName . ' ' . Auth::user()->lName;
$groups = Group::where('userId',Auth::user()->id)->get();
return view('pages.erp.warehouse', compact('welcome','groups'));
}
public function postWarehouse(Request $request)
{
$input = \Input::all();
$rules = array(
'masterCategory' => 'required|min:3|max:80'
);
$v = \Validator::make($input, $rules);
if ($v->passes()) {
$group = new Group;
$group->group = $input['masterCategory'];
$group->userId = Auth::user()->id;
$group->save();
return redirect('dash/warehouse');
} else {
return redirect('dash/warehouse')->withInput()->withErrors($v);
}
}
}
