Hello awesome Laravel community!!!

This is my events table in DB

			$table->increments('id');
			$table->string('title');
			$table->text('description');
			$table->string('categorie');
			$table->dateTime('datetimefrom');
			$table->dateTime('datetimeto');
			$table->time('timefrom');
			$table->time('timeto');
			$table->string('location');
			$table->string('image');
			$table->integer('user_id');
			$table->timestamps();

This is my Events controller!

//if validated makeing database insert!
    	$dateandtime = Input::get('datetimefrom');
    	$procedure = new Procedure;
    	$procedure->title = Input::get('title');
    	$procedure->description = Input::get('description');
    	$procedure->categorie = Input::get('categorie');
    	$procedure->datetimefrom = Input::get('datetimefrom');
    	$procedure->datetimeto = Input::get('datetimefrom');    
    	$procedure->location = 'Rīga, Lāčplēša iela 41/2';
    	$procedure->image = Input::get('image');
    	$procedure->user_id = Auth::user()->id;    	
    	$procedure->save();

The thing is with datetimefrom, datetimeto, timefrom, timeto,

These columns are, so I would be able to filter events by dateTime and by time! But I do not like to have so much fields in form!

So the question is can I use just one field "datetimefrom" and based on that field calculate other fields, take time from "datetimefrom" using $date->format('time') and post it in "timefrom"

Take "datetimefrom" field and add using this --> $date = new Date('+4 hour'); and pass it to "datetimeto"

and after that take this new date and format $date->format('time') and pass this to timeto.

I am using this package --> http://jenssegers.be/projects/laravel-date

I am wondering is it possible, and what could be solution to make it happen!

Thanks you all in advance!
