I'm having a little problem getting PHP and Javascript to work together on a little project i'm working on. Here's my problem,

I have a form that has to be sent to one file and it contains the fields i want to appear on a preview popup.
I did use a script (Below) that wrote a tempary file, but it did not work for me as it could not load a template into the file.

Can only help?

The Javascript i was using that wrote tempary files looks like this

<script language="JavaScript">

function preview() { 

temp = document.reply.message.value; 

preWindow = open("", 

"preWindow"," menubar=yes, scrollbars=yes"); 

preWindow.document.open(); 

preWindow.document.write(temp); 

preWindow.document.close(); 
}; 

</script>

Then i done a onclick (Form Button) to send it to preview().

What i really need is a javascript that will either set a cookie or see what is in the field and post it to another page.

Im confused.. are you doing PHP? just Get/Post th evariable from one page to another you can swing them as many times you want

Do you want a Preview windows to showup all the data Entered in a HTML form?

If you want your popup window to show all the entered values in form of parent window, then you don't have to pass them to child windows. Instead you can use
"opener.document.getElementById('element').val ue'
