How i can compare Two input values at the time of validation

Question

when I submit the form, I want to compare two input values at the time of validation in Controller store function

array(
'name' => 'required',
'password' => 'required|min:8',
'email' => 'required|email|unique:users',
'rule'=>'input1'<'input2',
)

Answer 1

I assume your rule property is not really an input field on the form or data. Because if rule is a property, like email, then I don't know what you want to validate it against. (rule is only valid if input1 is smaller than input2?)

Maybe you actually want to validate the input1 attribute like this:

array(
    'name' => 'required',
    'password' => 'required|min:8',
    'email' => 'required|email|unique:users',
    'input1'=> 'lt:input2',
)

Do mind that input1 and input2 must be of the same type. See: https://laravel.com/docs/5.8/validation#rule-lt
