Window.open With Form

[sungpeng]

<script>
function open_win() 
{
window.open ("chats.php","mywindow","menubar=1,resizable=1,width=350,height=500");
}
</script>
<form name="form" method="post" onsubmit="return open_win();">
<select name="cpid">
<option value="2">2</option>
</select>
<input type="submit" name="talk" value="Chat">
</form>

 

Please help. I can't get the value $_POST[cpid] from chats.php.

You coulds pass the value of the select into the js function and append it on the URL and dectect the value on the pop-up using $_GET

function open_win(val) {
window.open ("chats.php?id="+val,"mywindow","menubar=1,resizable=1,width=350,height=500");
}

var val = "<?php Print $_REQUEST[cpid]; ?>";

The first attempt I clicked submit button the value passed to the function open_win.

To my surprise the first time "val" return as 0 in value.

The second attempt I clicked submit button the value of the first attempt is reflected out from "val"

Please help..

I think when the form called out open_win(), the $_REQUEST[cpid]; is empty so it reflect the empty value first instead of the value that passed from the form which is 2. Anyway to solve it ?
