Limit number of files that can be uploaded

Question

How can I limit the number of files that can be uploaded?

The max validation seems to apply to the size of the image (in kilobytes). How can I make a va

Answer 1

In laravel, there is no built-in validation rule for that. But you can create custom-validation rule to handle this.

Here is a simple custom-validation rule for it.

Create customValidator.php in app/ directory.

Validator::extend('upload_count', function($attribute, $value, $parameters)
{   
    $files = Input::file($parameters[0]);

    return (count($files) <= $parameters[1]) ? true : false;
});

Don't forget to add it to app/start/global.php

require app_path().'/customValidator.php';

In your validation setting,

$messages = array(
    'upload_count' => 'The :attribute field cannot be more than 3.',
);

$validator = Validator::make(
    Input::all(),
    array('file' => array('upload_count:file,3')), // first param is field name and second is max count
    $messages
);

if ($validator->fails()) {
     // show validation error
}

Hope it will be useful for you.

How I did in laravel 7.x

Create a new form request class with the following command

php artisan make:request UploadImageRequest

use Illuminate\Foundation\Http\FormRequest;
use App\Http\Requests\BaseFormRequest;

class UploadImageRequest extends BaseFormRequest
{
public function authorize()
{
  return true;
}

public function rules()
{
  return [
    'coverImage.*' => 'image|mimes:png,jpg,jpeg,gif,svg|max:2048',
    'coverImage' => 'max:5',
  ];
} 

public function messages() {
  return [
    'coverImage.*.max' => 'Image size should be less than 2mb',
    'coverImage.*.mimes' => 'Only jpeg, png, bmp,tiff files are allowed.',
    'coverImage.max' => 'Only 5 images are allowed'
  ];
}

in View.blade.php

<input type="file" id="coverImage" name="coverImage[]"
                        class="form-control-file @error('coverImage') is-invalid @enderror" multiple>                        
@error('coverImage')
 <span class="text-danger">{{ $message }}</span>
@enderror

in controller

public function store(UploadImageRequest $request)
{
  //code
}
