Laravel Validating Arrays - pass 2 parameters?

Question

I need to extend laravel validator creating a new validator but the problem is that I need to pass 2 parameters, one for days and one for slots. How to solve this?

Example dd($request->all) dump:

array:2 [
  "days" => array:2 [
    0 => "1" // Mon
    1 => "2" // Tue
  ]
  "slots" => array:2 [
    1 => array:2 [
      "open" => "09:00"
      "close" => "11:30"
    ]
    2 => array:2 [
      "open" => "16:00"
      "close" => "21:00"
    ]
  ]
]

It need to loop through days and check with slots.

Pseudo code, example:

foreach($days as $day) {
  foreach($slots as $slot) 
   {
      // Validation Logic for $day and $slot (open and close)
   }
}

This is the correct method of making a custom Laravel Validation

Create your own Validation Service Provider using

php artisan make:provider ValidationServiceProvider

then go to config\app.php and add this to providers

App\Providers\ValidationServiceProvider::class

Now go to ValidationServiceProvider.php and add

use Validator;

to the top...

and this in the boot() function

Validator::extend('days_with_slots', function($attribute, $value, $parameters, $validator) {
  $slots = request()->get('slots');

  if(!is_array($slots)) return false;

  foreach($days as $day) {
    foreach($slots as $slot) {
      if(empty($slot[$day]) || empty($slot[$day]['open'] || empty($slot[$day]['close']))) {
        return false;
      }
    }
  }
});

Finally, use this in your rules

$rules['slots'] = 'days_with_slots'

You can also add a custom message for it, say

$message['days_with_slots'] = 'Open and Close Timings are required for the days selected'

Hope this helps :)
