How to add required if validation rule if a file has been uploaded

Question

I'm working with Laravel 5.8 and here is my validation request form:

public function rules()
    {
        return [
            'art_audio_file' => ['nullable', 'file', 'mimes:audio/mpeg,mpga,mp3,wav,aac'],
            'art_audio_file_title' => ['required_if: IF USER HAS UPLOADED FILE']
        ];
    }

I wonder, how can I make art_audio_file_title required if art_audio_file is not empty.

So how can I do that?

Hasn't this been asked already today? – brombeer Jul 26 '22 at 11:00 — brombeer, Jul 26 '22 at 11:00

You can add your logic like below:

return [
      'art_audio_file' => ['nullable', 'file', 'mimes:audio/mpeg,mpga,mp3,wav,aac'],
      'art_audio_file_title' => [
          Rule::requiredIf(function() {
              return !empty($this->request->get('art_audio_file'));
          })
      ]
    ];

or in your case simply:

'art_audio_file_title'=>'required_with:art_audio_file'

Call to undefined method Illuminate\Contracts\Validation\Rule::requiredIf() – Pouya Jul 26 '22 at 11:11
And the second one also not working – Pouya Jul 26 '22 at 11:12
You must use it before call. `use Illuminate\Validation\Rule;` – Pooya Sabramooz Jul 26 '22 at 11:17
I have included it now, I tried choosing a file to upload, I left the `art_audio_file_title` empty to check if it shows the required message, but it adds the data to the DB without showing require message! – Pouya Jul 26 '22 at 11:21
Both required_with helper function and requiredIf Rule is available in your laravel version, you can see this: https://laravel.com/docs/5.8/validation – Pooya Sabramooz Jul 26 '22 at 11:21
Its weird, please add your request parameters bag sample and your HTML snippet to the question. – Pooya Sabramooz Jul 26 '22 at 11:23
