Here is a Question I make assignment submition  page for certain collage so how can I control user not to submsit out of the time allocated to submit.  that means doesn'ta allow user submiting their assignment after the penality time.

so how can Imke this control????????

create a login system and in the user account table have a column that holds the last submitted thing and then when user tries to submit another one, check to see if that time is less than what you want it to be.

 

edit:

 

or actually, I think i misunderstood your question...i really have no idea how the rest of your site is setup, so i couldn't possibly tell you the best/easiest way to do it, but you can do something as simple as

 

$cutoff = 'sometime';

$currenttime = time();

if ($currenttime > $cutoff) {

  // no submission

} else {

  // submit

}
