How to use gte rule in laravel in case of optional fields?

Question

Laravel

Hello.

I have something like this in my form request

public function rules()
{
    return [
        'min_price' => 'nullable|numeric|min:0',
        'max_price' => 'nullable|numeric|min:0|gte:max_price',
    ];
}

Both fields are optional.
But if I only specify max_price, I get an error that the value must be greater than or equal to min_price.

I don't need to make any of the fields required.
The idea is as follows.

• The user can only specify min_price and not max_price.
  
• The user can only specify max_price and not specify min_price.
  
• The user can fill in both fields.
  
• The user can leave both fields blank.
  

And only in the case when both fields are filled, I want to additionally check that the value of max_price is greater than or equal to min_price.
It's just that if min_price is not specified, then this check loses all meaning.

Is there really no way to bypass this and have to write a custom rule?
This is a fairly common case. Doesn't laravel know how to take field optionality into account in such cases?

Thank you.
