returning a clicked variable??

wpfn

I have a function that draws a calendar.....each day is a clickable link, how would I return the value of the day that was clicked? The dates are displayed with the following code if that help....thanks in advance :-)

echo "<td width='100' align='right' valign='top' bgcolor=\"#FFFFFF\"><a href='daydraw.php'>" . $dayNumber ."</a></td>\n";

By using a name/value pair in the query string, e.g.

daydraw.php?dayNumber=$dayNumber

wpfn

Thanks for the tip, I still must be too new....I've seen this used in other code but didnt understand it exactly. I've searched for it in the manual to no avail. I'll try and find other code and study that, but if you could point me in the right direction in terms of the manual or other examples I'd appreciate it. Thanks

wpfn

Ok I worked on that and got it. What if I also wanted to return the month and year with that? Is it done the same way with '&" signs between the variables?

One other quick question, these returned variables are strings, how would i convert them to integers so that calculations could be made with them? Thanks in advance.

To pass the day/month/year off to the next page you can use a link that would look like:

daydraw.php?day=$dayNumber&month=$monthNumber&year=$yearNumber

As for the calculations, you can do a quick

if(is_numeric($_GET['day'])) { [calculations] }

to see if your variable is actually a number then do the calculations with it.

As long as your string doesn't have any non-numeric characters PHP will allow you to manipulate it as an interger/float variable.

thanks so much for your help, I had a hell of a time trying to find this stuff in the manual or the books that I have for that matter.
