In Laravel 5.4, it appears that the withValidator() method gets executed even if the validation rules fail. Example:
class ClientAttachBusinessRequest extends FormRequest
{
public function rules()
{
return [
'businessName' => 'required',
'fromDate' => 'sometimes|nullable|date',
'toDate' => 'sometimes|nullable|date|greater_than_field:fromDate',
];
}
/**
* Configure the validator instance.
*
* @param \Illuminate\Validation\Validator $validator
*
* @return void
*/
public function withValidator( $validator )
{
$validator->after(
function ( $validator ) {
// Extract the business id from the string.
$businessString = $this->request->get( 'businessName' ); // Start with "Murazik-Swaniawski (ID: 30)"
$businessString = explode( "ID:", $businessString ); // Now have "30)"
$businessId = rtrim( $businessString[ 1 ], ")" ); // Now have "30"
// Find the business Record
$this->business = Business::where( 'id', $businessId )->get()->first();
if ( $this->business ) {
$businessName = $this->business->businessName;
$client = Client::find( $this->client_id );
if ( $client->businesses->contains( $this->business->id ) ) {
$validator->errors()->add(
'businessName',
"The business: <strong>$businessName</strong> is already attached to this Client (See above ⬆ ). Please select another." )
;
}
}
$validator->errors()->add( 'businessName', 'Invalid business.' );
}
);
}
}
The documentation indicates that the withValidator() method is used as an "AFTER hook to a form request".
Now, if the businessName submitted is empty (""), then withValidator() will fail with this code because it can't extract the businessId from the submitted string.
Sure, I could check for a valid businessName string before I do that, but I'm curious to know how I could check for any validation rules that have already failed upon entering withValidator()?
Ah, never mind. I found this nifty little method:
public function withValidator( $validator )
{
if ( $validator->fails() ) {
// Handle errors
}
...
}
...that I can use at the beginning of the withValidator() method.
Too late but this is the other way you can do it:
public function withValidator(Validator $validator)
{
$validator->after(function (Validator $validator) {
$validatedData = $validator->safe()->all();
...
});
}
