Hello fellas

 

I have been working on this piece of php for over a week now and I have got a few questions.

 

1. Where is the $selected_date is being read from ? given that this is a unixtime stamp format , should it not get converted with date function ? The code however is working fine with Gregorian calendar but with persian calendar time conversion , the $selected_date returns as year 1970 instead of 2014.

 

 

2. by clicking <a href='calendar.php?month=" . $this->month . "&year=" .  $this->year . "&day=" . sprintf("%02s", $daynumber) . "'>

 

what function is being called ?

 

 

 

** the make_time and mds_date are actually from a separated php class which is responsible for the date year and day conversion
