Laravel: Validate min and max value based on input fields

Question

I am trying to add validation for the min and max values. Both these values are coming from input fields.

I want to validate that max value (max_price) should always be greater than min value (min_price).

I am working on the Laravel 5.7

$validator = validator($request->all(),[
  'min_price' => 'required|min:1"',
  'max_price' => 'required|numeric|min:min_price',
]);

Solution 1

You can use the code below

$validator=validator($request->all(),[
    'min_price'=>'required|min:1',
    'max_price' => 'required|gt:min_price'
]);

• https://laravel.com/docs/5.7/validation#rule-min

Solution 2

You can use the rule gt (Greather than) that expect the number of another field as first argument:

'min_price'=>'required|numeric|min:30',
'max_price'=>'required|numeric|gt:min_price'
