Laravel validations

Question

I want to validate my backend code with the following data.I passed date as $request->get('date_from'),$request->get('date_to') and time as $request->get('time_from'), $request->get('time_to') from my angular frontend and I convert date time as follows.

$dateTime_from=date('Y-m-d',strtotime($request->get('date_from'))).' '.$request->get('time_from');
$dateTime_to=date('Y-m-d',strtotime($request->get('date_to'))).' '.$request->get('time_to');

Now I want to validate DateTime with laravel backend validations. dateTime_from should be less than dateTime_to.How can write down that code inside validator?

$this->validate($request, [
            'vehicle_id'=>'required',
            'time_to'=>'required',
            'event_id'=>'required',

        ]);

You can use the after validation rule.

$this->validate($request, [
  'vehicle_id' => 'required',
  'date_to'    => 'required|after:date_from',
  'event_id'   => 'required'
]);

@GayalSeneviratne Isn't that what he has posted?

@Cerlin not only date_from should be less than $date_to. For instance, let's say if frontend passed same $date_from and $date_to. I want to clarify with the time too. for example $dateTime_from=2019-1-5 08:30:00 $dateTime_to=2019-1-5 07:00:00 then this instance $dateTime_from greater tha the $dateTime_to. this is the issue I want to handle

Laravel uses php's strtotime method. So time will also be considered while validating. So please try the solution mentioned above

https://laravel.com/docs/5.8/validation#rule-after

you can use the after rule like follows

'date_to' => 'required|date|after:date_from'

Instead of passing a date string to be evaluated by strtotime, you may specify another field to compare against the date:

Also, you have rule-before as well

EDIT I think after rule takes the time into consideration as well, but not sure.

And you have really complex validation to do, better write a custom rule class or a closure to handle it for you

'date_to' => [ 'required', 
               'date',
               function ($attribute, $value, $fail) {
                  if (strtotime($value) <= strtotime($request->date_from) {
                  $fail(':attribute needs to be higher than date_from!'); // or whatever mesage ou need to send
               }
             ]
