passing php/javascript variable to a popup window

jshowe

<FORM name="TheForm" method="post">
<input type="text" name="test" value="85">
<a href="javascript😛opUp('display.php?itemnum=document.TheForm.test.value')">Make Popup</a>

This doesn't work at all.... Is there a way that I can pass a value like this?

If you have variables in a PHP page, you should be able to pass them through the URL and use $_GET[] to access them in the popup.
<a href="javascript😛opUp('display.php?itemnum=<? echo $var; ?>')">Make Popup</a>

Then in display.php, use $_GET['itemnum']

Thank you very much! I will do just that!

One more thing - I haven't sat down to try it yet but do you think it will make problems if the variable is a form element like a select box?

I've passed an argument from a select-box to a popup-window(for map/directions to different discount-stores), and this worked out just fine.

When I load the page I think the php has already run and it is just a blank after ?itemnum= . What am I doing wrong?

function PopUp(url) { window.open(url,"MyPopup",'height=200,width=300'); }
</SCRIPT>
</HEAD>
<BODY>
<FORM name=TheForm method="GET">

<SELECT name=Product01>
<OPTION value=145>145</OPTION>
<OPTION value=125>125</OPTION>
</SELECT>
</FORM>
<a href="java script😛opUp('display.php?itemnum=<? echo $Product01; ?>')">Make Popup</a>
</BODY>
</HTML>
