Laravel validation difference between 2 dates - php

Question

I need to check some special validation in my action store
public function store(Request $request) {
$this->validate($request, [
'practice'=>'required|max:100',
'project'=>'required',
'work_place'=>'required',
'telephone_1'=>'required',
'date_recurring_for_beginning' => 'required|date',
'date_recurring_for_end' => 'required|date|after_or_equal:date_recurring_for_beginning',
]);
RequestCollaborator::create($request->all());
return redirect()->route('requestsCollaborator.index')
->with('flash_message',
trans('request.request_created'));
}
I have to validate if the difference between date_recurring_for_beginning and date_recurring_for_end is 3 months?
there is any solution for doing this or I have to create a custom validation?

Answer 1

You can use Validator::extend() and can create your custom validation rule. Like
Validator::extend('valid_date_range', function ($attribute, $value, $parameters, $validator) {
$dateBeginning = \Carbon::createFromFormat('Y-m-d', $parameters[0]); // do confirm the date format.
$dateEnd = \Carbon::createFromFormat('Y-m-d', $value);
return $dateBeginning->diffInMonths($dateEnd) == $parameters[1];
});
You can use this like:
'date_recurring_for_end' => 'required|date|valid_date_range:date_recurring_for_beginning,3'
For more details about the custom validation. Please follow the documentation.

Answer 2

Create a custom validation rule within your app/Providers/AppServiceProvider:
public function boot()
{
Validator::extend('date_difference', function ($attribute, $value, $parameters, $validator) {
$firstDate = Carbon::parse($parameters[0]);
$secondDate = Carbon::parse($parameters[1]);
$minDifference = (int)$parameters[2];
if($firstDate->diffInMonths($secondDate) < $minDifference)
return false;
return true;
});
}
To use this rule:
$this->validate([
'some_field' => 'date_difference:date_one,date_two,3',
]);
Hope it helps.
