Laravel Validation on storage path - laravel

Question

As an example of Laravel validation:
$validatedData = $request->validate([
'title' => ['required', 'unique:posts', 'max:255'],
'body' => ['required'],
]);
I want to add path exists or not in storage .
Storage::exists('/path/to/your/directory');
Based on this I want to do something like :
$validatedData = $request->validate([
'title' => ['required', 'unique:posts', 'max:255'],
'body' => ['required'],
'path' => ['storage_file_exists_or_not']
]);
How to achieve that. Thanks.

You can create a custom rule using
php artisan make:rule StorageFileExists
and specify your condition inside the passes function and write your message.
<?php
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
use Illuminate\Support\Facades\Storage;
class StorageFileExists implements Rule
{
/**
* Determine if the validation rule passes.
*
* #param string $attribute
* #param mixed $value
* #return bool
*/
public function passes($attribute, $value)
{
return (Storage::exists($value)) ? false : true;
}
/**
* Get the validation error message.
*
* #return string
*/
public function message()
{
return 'File is present.';
}
}
and write validation rule like this
$request->validate([
'path' => new StorageFileExists(), // your Rulename
]);
