Validator Does Not Show Errors At Blade - php

Question

I have a Controller method like this:
use Validator;
public function insert(Request $request)
{
$data = Validator::make(request()->all(),[
'title' => 'required',
'name' => 'required|alpha_num',
'activation' => 'nullable',
'cachable' => 'nullable'
])->validated();
$wallet = new Wallet();
$wallet->title = $data['title'];
$wallet->name = $data['name'];
if (!empty($data['activation'])) {
$wallet->is_active = 1;
} else {
$wallet->is_active = 0;
}
if (!empty($data['cachable'])) {
$wallet->is_cachable = 1;
} else {
$wallet->is_cachable = 0;
}
$wallet->save();
return redirect(url('admin/wallets/index'));
}
And then I tried showing errors like this:
#error("name")
<div class="alert alert-danger">{{$message}}</div>
#enderror
But the problem is, it does not print any error when I fill the form incorrectly.
So how to fix this and show errors properly?
Here is the form itself, however it submits data to the DB correctly:
<form action="{{ route('insertWallet') }}" method="POST" enctype="multipart/form-data">
#csrf
<label for="title" class="control-label">Title</label>
<br>
<input type="text" id="title-shop" name="title" class="form-control" value="" autofocus>
#error("title")
<div class="alert alert-danger">{{$message}}</div>
#enderror
<label for="title" class="control-label">Name</label>
<br>
<input type="text" id="title-shop" name="name" class="form-control" value="" autofocus>
#error("name")
<div class="alert alert-danger">{{$message}}</div>
#enderror
<input class="form-check-input" type="checkbox" name="cachable" value="cashable" id="cacheStatus">
<label class="form-check-label" for="cacheStatus">
With Cash
</label>
<input class="form-check-input" type="checkbox" name="activaton" value="active" id="activationStatus">
<label class="form-check-label" for="activationStatus">
Be Active
</label>
<button class="btn btn-success">Submit</button>
</form>

Answer 1

check the official documentation here
add the following code
if($data->fails()){
return redirect(url('admin/wallets/index'))->withErrors($data)->withInput();
}
And after that save your data in your database

Answer 2

You are not returning any errors, you are just redirecting back to the view without any data.
Your fix would be to have your validator as this:
$data = Validator::validate(request()->all(),[
'title' => 'required',
'name' => 'required|alpha_num',
'activation' => 'nullable',
'cachable' => 'nullable'
]);
See that I have changed Validator::make to Validator::validate. As the documentation states:
If the validation rules pass, your code will keep executing normally; however, if validation fails, an exception will be thrown and the proper error response will automatically be sent back to the user.
If validation fails during a traditional HTTP request, a redirect response to the previous URL will be generated. If the incoming request is an XHR request, a JSON response containing the validation error messages will be returned.
So, if your validation passes, it will save all the validated data into $data, as you did with ->validated() (but you don't have to write it here), and if it fails, it will automatically throw an Exception, in this case ValidationException, so Laravel will automatically handle it and redirect back with to the same URL and with the errors. So it now should work...
This is the Validator::validate source code and this is the validate source code for the validator validate method.
