Handling values between browser windows

[Anon]

I'm trying to make an online form, but I can't figure out how to do this:
The user must be able to click a link that will open a new window, where he/she will choose a value, then, I need the value TO BE TAKEN BACK TO THE CALLING FIELD IN THE FORM.

Has anyone accomplished something like this?

I was reading some javascript examples..you should check them out..
you can pass the values back and forth using that..and when u are done..then u can use php to process it....

otherwise..you can you use:

a link to open a new window and pass the variables, then when they are done..

<a href="../newWindow.php?var1=<?echo $var1?>&var2=<?echo $var2?>">Open New window</a>

here is a link to the javascript site..(scroll down...)

...or the use of cookies could be implented...

<?
setcookie("somename","somevalue","expiredate")
?>

then use
if isset($somename)) {
do whatever with $somename here;
}
