Validate favicon on controller from form

Question

i want to validate my file, only .ico files. Laravel dont include x-icon mime I think, how can i validate it?

  $logo = $request->file('logo');
  $favicon = $request->file('favicon');

  $request->validate([
    'logo'=>'image|mimes:png',
    'favicon'=>'',
     ]);

Answer 1

Make a custom validation rule as explained here.

In short:

First do:

php artisan make:rule CheckIfFavicon

Then:

Create the validation code in the created Rules-file.

Try something like:

  public function passes($attribute, $value)
        {
            return $value->getClientOriginalExtension() == 'ico';
        }

Then ad it to the validation. Note, that if you make a custom validation class you will have to change the syntax in the $request->validate([...]) from pipe-ing to array.

$request->validate([
    'favicon' => [new CheckIfFavicon], 
]);
