Custom error messages for array input

Question

Consider the following <input> array in my form:

 <input type="text" name="title[1]" value="">
 <input type="text" name="title[2]" value="">
 <input type="text" name="title[3]" value="">

The numbers (1,2,3) refer to different languages. 1 = English, 2 = German, etc.

How can I add custom error messages for an input array?

---

I have tried the following without success in my app/lang/en/validation.php:

<?php   
    return [
        'custom' => [
            'title.1' => [
                'required' => 'The english title is required.',
            ],
            'title.2' => [
                'required' => 'The german title is required.',
            ],
            'title.3' => [
                'required' => 'The italian title is required.',
            ],                                                                
        ],
    ];
?>

Laravel throws the default error messages instead of using my custom messages:

The title.1 field is required.
The title.2 field is required.
The title.3 field is required.

Thank you for any help you can provide!

EDIT: It works if I pass the message to my validator like this:

$messages = array(
    'title.1.required' => 'The english title is required',
);
$validator = Validator::make($data = Input::all(), $rules, $messages);

But I can't get it to work in the app/lang/en/validation.php file.

By using below way i got solution

In Controller

        $input=array (
          'name' => 'pro 1',
          'barcode' => '2222',
          'vendors' => 
          array (
            0 => 
            array (
              'id' => 51,
              'name' => 'v1',
              'item_code' => 'khgjhgjhkhjgjhgjhkhjgjhgjhkhjgjhgjhvv',
            ),
            1 => 
            array (
              'id' => 43,
              'name' => 'v3',
              'item_code' => 'aerfaf132aw1d32aw1d32wad',
            ),
          ),
        ) 
        $validation = Product::validate($input);
          if ($validation != null && $validation != "" && $validation->fails()) {
            $breakline = $validation->messages()->all();
            $message = implode("<br> ", $breakline);
            Log::warning('Admin::ProductsController::store::' . $message);
            return Response()->json('', $message));
          }  

In Model

public static function validate($data) {
  $rule = array(
    'name' => 'required|max:255',
    'barcode' => 'required|max:255',
    'vendors'=>'present|array|size:1,5',
    'vendors.*.item_code' => 'max:6'
  );
  $messages = array(
    'required' => ':attribute field is required.',
    'name.max' => ':attribute may not be greater than :max characters.',
    'barcode.max'=>':attribute may not be greater than :max characters.'
    'size'=>'only allowed one to five vendor.',
  );
  $data = Validator::make($data, $rule, $messages);
  $data->setAttributeNames(array(
    'name' => ucfirst('name'),
    'barcode' => ucfirst('barcode'),
    'vendors.*.item_code' => ucfirst('item code'),
  ));
  return $data;
}

It will show

Item code may not be greater than 6.
Item code may not be greater than 6.

The dot notation is used to access nested array items, but you're using it for an array key. It expects title and 1 to be two distinct array keys nested in one another. That is probably why there's no match for your custom error messages. Instead try this:

return [
    'custom' => [
        'title' => [
            [ 1 => ['required' => 'The english title is required.']],
            [ 2 => ['required' => 'The german title is required.' ]],
            [ 3 => ['required' => 'The italian title is required.']],
        ],
    ],
];
