Keeping modal dialog open after validation error laravel - laravel

Question

So basically I have a blade.php, controller page and a form request page(validation). I'm trying to keep my modal dialog open if there is an error but I just cant figure it out, what part of code am I missing out on or needs to be changed?
blade.php
<div id="register" class="modal fade" role="dialog">
...
<script type="text/javascript">
if ({{ Input::old('autoOpenModal', 'false') }}) {
//JavaScript code that open up your modal.
$('#register').modal('show');
}
</script>
Controller.php
class ManageAccountsController extends Controller
{
public $userRepository;
public function __construct(UserRepository $userRepository)
{
$this->userRepository = $userRepository;
}
public function index()
{
$users = User::orderBy('name')->get();
$roles = Role::all();
return view('manage_accounts', compact('users', 'roles'));
}
public function register(StoreNewUserRequest $request)
{
// process the form here
$this->userRepository->upsert($request);
Session::flash('flash_message', 'User successfully added!');
//$input = Input::except('password', 'password_confirm');
//$input['autoOpenModal'] = 'true'; //Add the auto open indicator flag as an input.
return redirect()->back();
}
}
class UserRepository {
public function upsert($data)
{
// Now we can separate this upsert function here
$user = new User;
$user->name = $data['name'];
$user->email = $data['email'];
$user->password = Hash::make($data['password']);
$user->mobile = $data['mobile'];
$user->role_id = $data['role_id'];
// save our user
$user->save();
return $user;
}
}
request.php
class StoreNewUserRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
// create the validation rules ------------------------
return [
'name' => 'required', // just a normal required validation
'email' => 'required|email|unique:users', // required and must be unique in the user table
'password' => 'required|min:8|alpha_num',
'password_confirm' => 'required|same:password', // required and has to match the password field
'mobile' => 'required',
'role_id' => 'required'
];
}
}

Answer 1

Laravel automatically checks for errors in the session data and so, an $errors variable is actually always available on all your views. If you want to display a modal when there are any errors present, you can try something like this:
<script type="text/javascript">
#if (count($errors) > 0)
$('#register').modal('show');
#endif
</script>

Answer 2

Put If condition outside from script. This above is not working in my case
#if (count($errors) > 0)
<script type="text/javascript">
$( document ).ready(function() {
$('#exampleModal2').modal('show');
});
</script>
#endif

Answer 3

for possibly multiple modal windows you can expand Thomas Kim's code like following:
<script type="text/javascript">
#if ($errors->has('email_dispatcher')||$errors->has('name_dispatcher')|| ... )
$('#register_dispatcher').modal('show');
#endif
#if ($errors->has('email_driver')||$errors->has('name_driver')|| ... )
$('#register_driver').modal('show');
#endif
...
</script>
where email_dispatcher, name_dispatcher, email_driver, name_driver
are your request names being validated

Answer 4

just replace the name of your modal with "login-modal". To avoid error put it after the jquery file you linked or jquery initialized.
<?php if(count($login_errors)>0) : ?>
<script>
$( document ).ready(function() {
$('#login-modal').modal('show');
});
</script>
<?php endif ?>
