varibles within a web form being reused.

weaponx71

I have a web form that lets users input data. My particular question is about the dates. I am using a drop down date system the lets them choose month, day, and year, at the end of the form they hit submit and it brings up a confirmation page, after that it gets sent to the database. Everything works great, but now I want a new function.
The dates are save within there own varible such as $useryear, $usermonth, $userday. Within the HTML of the form a function is called to produce the dropdown lists for the date.
I want to add a certain number of years to the $useryear varible and save it under a new varible name.
I have tried making it into a new function but am unsure how to call the function within the form as the user doesnt see this addition happening, I can call the function, but now I am stuck on getting the varibles sent into the new function, manipulating them, and sending them back out as a new varible name.
No matter what I do, nothing of the new varibles gets sent on, and are never saved to the database.
As I said, the form works as it is, but I dont know how to take a value of a session varible and add to it, then have a new varible created with the new value.
Thanks for any help...

I want to add a certain number of years to the $useryear varible and save it under a new varible name.

$newvar = $useryear+3;

$newvar won't be passed on unless you stick it into a hidden field in the form

But it'd be easier to just alter the variable as wanted after they submit the form.

I don't know why your talking about session variables, if you have a pull down field in the form called useryear, then when the person clicks submit their choice can be accessed from the $useryear variable.

Or, $_POST['useryear'] if register globals is off.

I don't think you really need a function to add 3 to a year, imho.

you could also set up a calculation fucntion in your database.
add a new column and perform the caluclation there.

this will be performed every time a new record is entered.

I want to thank you both for your ideas, I was putting the code within the wrong section.
Everything works as it should now.
Thanks again for the ideas.
