I'm trying to combine all NotBlank error messages into one.
If the error array contains at least 1 error that is a NotBlank type, I want it to display only one message like "Please fill in all fields."
How can I do this?
Here's my twig code
{{form_start(form, {'attr': {'novalidate': 'novalidate'}})}}
<div>
{{form_widget(form.firstName)}}
{{form_widget(form.lastName)}}
</div>
<div>
{{form_widget(form.username)}}
{{form_widget(form.email)}}
</div>
<div>
{{form_widget(form.password.first, {'attr' : { 'placeholder' : 'Password' } })}}
{{form_widget(form.password.second, {'attr' : { 'placeholder' : 'Confirm Password' } })}}
</div>
<div>
{{form_label(form.birthday)}}
</div>
<div>
{{form_widget(form.birthday)}}
</div>
<div>
{{form_widget(form.gender)}}
</div>
<div>
{{form_widget(form.save)}}
</div>
{{ form_errors(form.firstName) }}
{{ form_errors(form.lastName) }}
{{ form_errors(form.username) }}
{{ form_errors(form.email) }}
{{ form_errors(form.password.first) }}
{{form_end(form)}}
You can create a CallbackValidator
http://symfony.com/doc/current/reference/constraints/Callback.html
and in the validate method, check if at least one of the desired fields is blank, and if true, call
/**
* #Assert\Callback
*/
public function validate(ExecutionContextInterface $context)
{
if(empty($this->field1) || empty($this->field2)) {
$context->addViolation($message);
}
}
This way you will receive a global form error.

What I have
I have a form with 3 inputs and I want to check the following conditions:
All inputs are integers and they are required.
We do a math operation with all the numbers and we get if the operation was successfull or not.
Success: we redirect the user to a success page.
No success: we show a error message to the user with a message explaining him that the numbers aren't valid.
I resolved this with the following lines.
Controller:
function formAction(Request $request) {
$this->validate($request, [
'number1' => 'integer|required',
'number2' => 'integer|required',
'number3' => 'integer|required',
]);
$numbers = $request->all();
$isValid = MyOwnClass::checkMathOperation($numbers);
if($isValid) {
return redirect()->route('success');
} else {
$request->session()->flash('error', 'The numbers are not valid.');
return back();
}
}
View (using Bootstrap):
<form method="POST" action="{{ route('form-action') }}">
#csrf
<div class="form-group">
<label for="number1">number1</label>
<input id="number1" name="number1" class="form-control {{ $errors->has('number1') ? ' is-invalid' : '' }}" />
</div>
<div class="form-group">
<label for="number2">number2</label>
<input id="number2" name="number2" class="form-control {{ $errors->has('number2') ? ' is-invalid' : '' }}" />
</div>
<div class="form-group">
<label for="number3">number3</label>
<input id="number3" name="number3" class="form-control {{ $errors->has('number3') ? ' is-invalid' : '' }}" />
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
#if ($errors->any())
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
What I looking for
When MyOwnClass::checkMathOperation($numbers) is false:
To highlight number1, number2 and number3 inputs.
To show an unique custom error message
To hide the number1, number2 and number3 input error messages.
How can I do that with validators?
Solution
Create a Form Request Validation called, for example, NumbersForm using:
php artisan make:request NumbersForm
The previous command creates a App/Http/Requests/NumbersForm.php file. Make authorize() returns true, put the validation rules into rules() and create a withValidatior() function.
class NumbersForm extends FormRequest
{
public function authorize() {
return true;
}
public function rules() {
return [
'number1' => 'integer|required',
'number2' => 'integer|required',
'number3' => 'integer|required',
];
}
public function withValidator($validator) {
$validator->after(function ($validator) {
$numbers = $this->except('_token'); // Get all inputs except '_token'
$isValid = MyOwnClass::checkMathOperation($numbers);
if(!$isValid) {
$validator->errors()->add('number1', ' ');
$validator->errors()->add('number2', ' ');
$validator->errors()->add('number3', ' ');
$validator->errors()->add('globalError', 'The numbers are not valid.');
}
});
}
}
Note: It's not important the text in the second param of $validator->errors()->add('number1', ' ');, but it can't be empty. If it is an empty string, $errors->has('number1') returns false, and the field won't be hightlighted.
Set the controller like this:
use App\Http\Requests\NumbersForm;
function formAction(NumbersForm $request) {
$this->validated();
return redirect()->route('success');
}
And, finally, if we want to print an unique error message, we must remove the following lines from view:
#if ($errors->any())
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
and replace them with:
#if ($errors->has('globalError'))
<div class="alert alert-danger">
{{ $errors->first('globalError') }}
</div>
#else
#if ($errors->any())
<div class="alert alert-danger">
<ul>
#foreach ($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
#endif
I haven't tested this but I think it can get you going in the right direction.
1 // Highlight the inputs
You can do this by accessing the error object within your view. This object is an instance of the MessageBag object.
Here is the docs: https://laravel.com/docs/5.7/validation#working-with-error-messages
Example:
// if the error exists for the input the class will be added
<input class=" {{ $error->has('number1') ? 'highlight' : '' }}" name="number1">
<input class=" {{ $error->has('number2') ? 'highlight' : '' }}" name="number2">
<input class=" {{ $error->has('number3') ? 'highlight' : '' }}" name="number3">
2 & 3 // Show a unique custom error message and hide the default messages
See the validator docs: https://laravel.com/docs/5.8/validation#custom-error-messages && https://laravel.com/docs/5.7/validation#working-with-error-messages -- this should solve both of these.
There is a validator callback and I think you can pass your second validation into that. If these numbers aren't valid then you can add your custom error messages and access them the same way as I did above.
function formAction(Request $request) {
$validator = $this->validate($request, [
'number1' => 'integer|required',
'number2' => 'integer|required',
'number3' => 'integer|required',
]);
$validator->after(function ($validator) {
$numbers = $request->all();
$isValid = MyOwnClass::checkMathOperation($numbers);
if(!$isValid) {
$validator->errors()->add('number1', 'Unique message');
$validator->errors()->add('number2', 'Unique message');
$validator->errors()->add('number3', 'Unique message');
}
});
}
Custom Validation Rules:
To add custom messages and validation you can also write a custom validation rule
Example:
class Uppercase implements Rule
{
/**
* Determine if the validation rule passes.
*
* #param string $attribute
* #param mixed $value
* #return bool
*/
public function passes($attribute, $value)
{
return strtoupper($value) === $value;
}
/**
* Get the validation error message.
*
* #return string
*/
public function message()
{
return 'The :attribute must be uppercase.';
}
}
Custom Error Messages:
You could also add custom error messages for rules within a Request:
public function messages()
{
return [
'number1.required' => 'My custom message telling the user he needs to fill in the number1 field.',
'number1.integer' => 'My custom message telling the user he needs to use an integer.',
];
}
I want to send array of additional_feature that they are exist to flash message. Now i only send one additional_feature. Any suggestion how can i do that?
if(!empty($additional_features)){
foreach($additional_features as $additional_feature){
$data = [
'name' => $additional_feature,
];
if (!Feature::where('name', '=', $additional_feature)->exists()) {
$additional = Feature::firstOrCreate($data);
$additional_ids[] = $additional->id;
}
else{
return redirect()->back()->withFlashMessage($additional_feature . ' exists!');
}
}
}
You can use session() instead of with():
session->flash('someVar', $someArray);
Another thing you could try is to seriallize array and pass it as string. Then unserilize it and use.
Also, you could save an array using simple session:
session(['someVar' => $someArray]);
Then get it and delete manually:
session('somevar');
session()->forget('someVar');
We had the same problem and forked the package. you can find it here:
Forked at first from Laracasts/Flash to use multiple message
#if (Session::has('flash_notification.message'))
#if (Session::has('flash_notification.overlay'))
#include('flash::modal', ['modalClass' => 'flash-modal', 'title' => Session::get('flash_notification.title'), 'body' => Session::get('flash_notification.message')])
#else
<div class="alert alert-{{ Session::get('flash_notification.level') }}">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
{!! Session::get('flash_notification.message') !!}
</div>
#endif
#endif
And the content of the include flash::modal
#if (Session::has('flash_notification.messages'))
#foreach (Session::get('flash_notification.messages') as $flashMessage)
#foreach($flashMessage as $type => $message)
<script>
$(function() {
var message = ('{{ $message }}<br>').replace(/'/g, "’");
customFlashMessage({
type: "{{ $type }}",
message: message
});
});
</script>
#endforeach
#endforeach
#endif
return redirect()->back()->with(['session1' => $value, 'session2' => $value]);
In the blade template:
{{ Session::get('session1') }}
{{ Session::get('session2') }}
In the blade view file, I have something like this:
{{ Form::text('contact_name', null, ['class' => 'form-control']) }}
#if ($errors->has('contact_name'))
<div class="error-block">{{ $errors->first('contact_name') }}</div>
#endif
{{ Form::text('contact_email', null, ['class' => 'form-control']) }}
#if ($errors->has('contact_email'))
<div class="error-block">{{ $errors->first('contact_email') }}</div>
#endif
When user press submit, it will check inputs validation in the controller. However, if there is an error with the validation, it will then redirect back to a form and populate it with error messages {{ $errors->first() }}
Is there a way to exclude {{ $errors->first() }} in the view file and still show error messages if validation failed? So combine Form::text and $errors->hasinto one function or something like that?
Use a Form Macro to do this
Form::macro('myText', function($field)
{
$string = Form::text($field, null, ['class' => 'form-control']);
if ($errors->has($field)) {
$string .= $errors->first($field);
}
return $string;
});
Then in your view
{{ Form::myText('contact_email') }}
One of the coolest Laravel feature is, Laravel pre-filled the form fields if validation error occurred. However, if a page contain more than one form, and form fields have same name, Laravel pre-filling all forms fields.
For example:
I have a page where i have two forms to create new users or whatever.
<h1>Create user1</h2>
{{ Form::open(array('url' => 'foo/bar')) }}
{{ Form::text('name', null) }}
{{ Form::email('email', null) }}
{{ Form::close() }}
</h1>Create user2</h1>
{{ Form::open(array('url' => 'foo/bar')) }}
{{ Form::text('name', null) }}
{{ Form::email('email', null) }}
{{ Form::close() }}
Controller
class UsersController extends BaseController
{
public function store()
{
$rules = [
'name' => 'required',
'email' => 'required'
];
$validation = Validator::make(Input::all(), $rules);
if ($validation->fails()) {
return Redirect::back()->withInput()->withErrors($validation);
}
}
}
As i didn't fill up the email, Laravel will throw validation error and pre-filling the forms as following:
How to tell Laravel that do not fill-up the second form?
There's no Laravel way of doing this, but you can use HTML basic form arrays to make it work. You need to understand that you have to identify your forms and fields so Laravel knows exactly where the data came from and where to send it back to. If all your fields have the same name how could it possibly know?
This is a proof of concept that will work straight from your routes.php file.
As I did it all and tested here before posting the answer I used Route::get() and Route::post(), to not have to create a controller and a view just to test something I will not use. While developing this you will have to put this logic in a controller and in a view, where I think they are alredy in.
To test it the way it is, you just have to point your browser to the following routes:
http://yourserver/form
and when you push a button it will automatically POST tho the route:
http://yourserver/post
I'm basically giving all forms a number and giving the buttons the number that we will usin in Laravel to get the form data and validate it.
Route::get('form', function()
{
return Form::open(array('url' => URL::to('post'))).
Form::text('form[1][name]', null).
Form::email('form[1][email]', null).
'<button type="submit" name="button" value="1">submit</button>'.
Form::close().
Form::open(array('url' => URL::to('post'))).
Form::text('form[2][name]', null).
Form::email('form[2][email]', null).
'<button type="submit" name="button" value="2">submit</button>'.
Form::close();
});
And here we get the data, select the form and pass all of it to the validator:
Route::post('post', function()
{
$input = Input::all();
$rules = [
'name' => 'required',
'email' => 'required'
];
$validation = Validator::make($input['form'][$input['button']], $rules);
return Redirect::back()->withInput();
});
This is how you use it in a Blade view, now using 3 forms instead of 2 and you can have as many forms as you need:
<h1>Create user1</h2>
{{ Form::open(array('url' => URL::to('post'))) }}
{{ Form::text('form[1][name]', null) }}
{{ Form::email('form[1][email]', null) }}
<button type="submit" name="button" value="1">submit</button>
{{ Form::close() }}
</h1>Create user2</h1>
{{ Form::open(array('url' => URL::to('post'))) }}
{{ Form::text('form[2][name]', null) }}
{{ Form::email('form[2][email]', null) }}
<button type="submit" name="button" value="2">submit</button>
{{ Form::close() }}
</h1>Create user3</h1>
{{ Form::open(array('url' => URL::to('post'))) }}
{{ Form::text('form[3][name]', null) }}
{{ Form::email('form[3][email]', null) }}
<button type="submit" name="button" value="3">submit</button>
{{ Form::close() }}
And you can even use a loop to create 100 forms in blade:
#for ($i=1; $i <= 100; $i++)
User {{$i}}
{{ Form::open(array('url' => URL::to('post'))) }}
{{ Form::text("form[$i][name]", null) }}
{{ Form::email("form[$i][email]", null) }}
<button type="submit" name="button" value="{{$i}}">submit</button>
{{ Form::close() }}
#endfor
Use old input with $request->flash().
https://laravel.com/docs/5.2/requests#old-input
I can't find a way to get Laravel to highlight the correct field when a _confirmation field is incorrect.
Using a Bootstrap layout I've got an email and email_confirmation field in my form like this:
<div class="control-group {{$errors->has('email') ? 'error' : ''}}">
{{ Form::label('email', 'Email', array('class' => 'control-label'))}}
<div class="controls">
{{ Form::email('email', Input::old('email'));}}
{{ $errors->first('email', Form::block_help(':message')) }}
</div>
</div>
<div class="control-group {{$errors->has('email_confirmation') ? 'error' : ''}}">
{{ Form::label('email_confirmation', 'Confirm Email', array('class' => 'control-label'))}}
<div class="controls">
{{ Form::email('email_confirmation', Input::old('email_confirmation'));}}
{{ $errors->first('email_confirmation', Form::block_help(':message')) }}
</div>
</div>
So if the user puts in an invalid email address then the 'email' field will have an error attached to it and the correct label/field will be highlighted.
But if the user has entered a valid/correct email address in the first field but gets the confirmation wrong - the error returned is still for the 'email' field, not the email_confirmed field.
To me it looks weird when the email field is highlighted when the error is actually with the email_confirmation field.
As far as I can understand from this stackoverflow question, I could probably do something like
{{$errors->first('email', ':message') == 'Please confirm your email address correctly.' ? 'error' : ''}}
This will work, but the problem is that I'm running a multi-lingual site so the :message that gets returned is going to be one of many possibilities.
I guess I could write a function to compare the :message against an array of messages for each language but I thought I'd check if there was an easier way to go about it.
Cheers!
This is how I show an inline error if the title field is empty:
<div class="form-group #if ($errors->has('title')) has-error #endif">
{{ Form::label('title', 'Title') }}
{{ Form::text('title', null, array('class' => 'form-control')) }}
#if ($errors->has('title')) <p class="help-block">{{ $errors->first('title') }}</p> #endif
</div>
And my validation rule:
public static $rules = array(
'title' => 'required',
);
Using Laravel 4 and Bootstrap 3.
Or you could just print all the Error messages somewhere
$messages = $validator->messages();
echo '<ul>';
foreach ($messages->all() as $message)
{
echo '<li>'.$message.'</li>';
}
echo '</ul>';
