Validation rules with dynamic file inputs

Question

My form allows users to add fields to upload a file dynamically.

<input type="file" name="your_file_{{ $i }}" id="your_file_{{ $i }}">

So it generates input names like: your_file_1, your_file_2, ...

Now I want to make these fields mandatory through validation rules, but I can't find a way to do that. I tried with a wildcard but it doesn't work.

$rules['your_file_*'] = 'required|mimes:pdf,doc,docx,png,jpg,jpeg|max:10000';

Any idea?

Answer 1

for($i = 1; $i <= count($request->all()) - 1; $i++) {
    $validate_array['var'. $i] = 'required';
}

$this->validate($request, $validate_array );
