If your select looks like this for example:
<div class="form-group row">
<label for="skills" class="col-md-4 col-form-label text-md-right">Skills</label>
<div class="col-md-6">
<select multiple name="skills[]" id="skills" class="form-control{{ $errors->has('skills') ? ' is-invalid' : '' }}" required>
<option value="ios">iOS</option>
<option value="php">PHP</option>
<option value="laravel">Laravel</option>
</select>
#if($errors->has('skills'))
<span class="invalid-feedback" role="alert">
<strong>{{ $errors->first('skills') }}</strong>
</span>
#endif
</div>
</div>
Create a custom request:
$ php artisan make:request ExampleRequest
ExampleRequest validation would look like this:
public function authorize()
{
return true;
}
public function rules()
{
return [
'skills' => 'required|array',
];
}
Then just grab the validated data from your $request directly
public function submitForm(ExampleRequest $request)
{
// at this point, validation already passed
// if validation failed, you would be back at form with errors
$skills = request('skills');
// or
$skills = $request->skills;
dd($skills);
}
Custom requests are being validated first before even hitting your controller method.
