Wasn't sure whether to put this in java or php, so I'm putting it here. I have a bit of java that opens a php page in a popup window, using this code:
So that code opens up "my_form.php" in a pop-up window. But I need to pass a value to that php page. Like with PHP, I could simply say <a href="my_form.php?value=25">Click Here</a>
But is there a way I can pass a variable through that link with the java script I've got?

Try adding ?value=25 on to the window.open function.
I have done something like this previously and it has worked.

Great idea. I tried that, and for some reason, it didn't work.
//this will set $value to the $_GET variable 'value' if it is there else set it to default of 'NOTHING POSTED'
$value = (isset($_GET[value])) ? $_GET[value] ? 'NOTHING POSTED'; //do something with $value
echo "Your age is ". $value; Last edited by peter_budo; Apr 5th, 2008 at 1:32 pm. Reason: Keep It Organized - please use [code] tags
