how would you assign NULL to a variable if its original value is ""? otherwise leave
it with its value...
the form im working on has a date field called "date" on the form itself. that "date"
will get turned into $_SESSION[add][date] on the next page...
i want it so if the person filling out the form didnt leave a date (left date field
blank) then it should be NULL so the mysql table will insert the current date...
so far i have this code:
if(empty($_SESSION['add']['date'])){
$_SESSION['add']['date']=NULL//or should it = FALSE??
}
//if its already filled do nothing else to it
is there a better way to do this than this way?
