variable from php page to php page via javascript

ktpmm5

I'm trying to pass a variable from one php file to a second one. The second php file is called via a javascript popup like this:

The PopUp code is as follows:

function popUp(){
if (wi) wi.close();
var level= $level;

wi=window.open('adddata.php?'+level,"","width=800,height=400,left=50,top=400,location=no,scrollbars=no,status=no");
}

Iwant to use the level variable in the second popup php page to get data from a db. Here is how I am calling the $level variable in the second php page:

<?php $level = $_GET['level'];
echo "level is $level"; ?>

This is not working, so I'm obviously not doing something right. Does anyone have any suggestions?

Oh, the level variable itself is passed from another php page - this is being passed correctly, so I'm sure it's my javascript (ok, not so sure....:-)

You didn't specify the level variable in the URL

Try:

function popUp(){
if (wi) wi.close();
var level= <? php echo $level;?>;

wi=window.open('adddata.php?level='+level,"","width=800,height=400,left=50,top=400,location=no,scrollbars=no,status=no");
}

I have tried that before and the popup will not even come up....

Have you tried:

url = 'adddata.php?level='+level;
wi=window.open(url,"","width=800,height=400,left=50,top=400,location=no,scrollbars=no,status=no");

ok, that seems to work (ie loads the window) - how do I retrieve the variable in the adddata.php window? I've tried:

$level=$_GET['level'];
echo "variable level is $level"

and this does not print out the correct value. Thanks for all ur help!

do you have the correct value in the query string

e.g. if level =2 do you have adddata.php?level=2 in the URL???

ok, I think that is the problem.

I know $level is set correctly in my php file, because I use it to select the proper table to get data from.

The problem is passing the $level variable to the popup window via javascript. This code:

url = 'adddata.php?level='+level;

wi=window.open(url,"","width=800,height=400,left=50,top=400,location=no,scrollbars=no,status=no");

will not even open a window. If I hardcode the line
var level = "varsity";
it will work, but obviously this is not what I want.
