Array validation is slightly different from other column validation in the laravel application. We can validate normal array keys and also nested array keys in Laravel. There are a bunch of validation functions in Laravel.

In this tutorial, I will show you how to validate array keys in laravel and how to validate nested array keys in Laravel. We will see examples one by one and I will try to clarify your doubts about Laravel array validation.

Let's see the first example of laravel associative array validation:


$input = [
    'country' => [
        'name' => 'Bangladesh',
        'area' => '147000',
        'is_ashian' => true,
$validator = Validator::make($input, [
    'country' => 'array:name,area',

if (!$validator->valid()) {
    return $validator->errors();


Look at that, the above validation was without using validation rules. Now we will see how to validate arrays in Laravel using validation rules.


$data = $request->validate([
    'facilities' => 'required|array|min:2',
    'facilities.*' => 'string|in:wifi,fridge,sports_room,prayer_room'


Now let's see the example of how to validate nested array in Laravel:


$data = $request->validate([
    'country.*.name' => 'required',
    'country.*.area' => 'required|email',


For this above validation, HTML input will look like this:

<div class="card">
    <input type="text" name="country[{{ $i }}][name]" placeholder="Name">
    <input type="text" name="country[{{ $i }}][area]" placeholder="Area">
