Modify request input value before validation

Hi,

I have a form with a phone input.

This input has an input mask like this 9999-999 9999

I'm using form request validation (App\Http\Requests\UserRequest.php)

I would like to validate the phone number should have 11 digits (digits:11)

I have tried $this->replace(['phone_number' => str_replace(...)]) and $this->merge(['phone_number' => str_replace(...)])

  • I know $this->replace will replace all request inputs

But none of those seems to work. Validation rule still take the original input.

can anybody help me?

You need to override the getValidatorInstance function and do the changes there, here is an example

public function rules()
{
    return [
        'email' => 'required|email',
        'phone_number' => 'numeric',
    ];
}

public function getValidatorInstance()
{
    $this->formatPhoneNumber();
    
    parent::getValidatorInstance();
}

protected function formatPhoneNumber()
{
    $this->request->merge([
        'phone_number' => str_replace('-', '', $this->request->get('phone_number'));
    ]);
}

Something like this should do!

Thank u! It did work!

    public function getValidatorInstance()
    {
        $this->cleanPhoneNumber();
        return parent::getValidatorInstance();
    }

    protected function cleanPhoneNumber()
    {
        if($this->request->has('phone_number')){
            $this->merge([
                'phone_number' => str_replace(['-','_',''], '', $this->request->get('phone_number'))
            ]);
        }
    }

I have been trying to do something like this, but for some reason it was not working for me. Currently working with Laravel 5.6.*

    protected function overrideWithUsersDetails()
    {
        if (auth()->check()) {
            $this->merge(array_replace_recursive($this->all(), ['message' => [
                'email' =>  auth()->user()->email,
                'name' =>  auth()->user()->name,
            ]]));
        }
    }

    public function getValidatorInstance()
    {
        $this->overrideWithUsersDetails();

        return parent::getValidatorInstance();
    }

This for me was the only way to replace the users submitted data, with the data I wanted to send along. Looks similar to the above approach, but did not quite work for me in its current form. Hope this helps someone out! Did not want to necro a thread, but might be a valid addition.

@BOBBYBOUWMANN - Should return parent::getValidatorInstance(); from getValidatorInstance() method. Currently, it returns null.
