This simple JavaScript code demonstrates how to use JavaScript in conjunction with SSI to display the user's IP address.

I found this interesting JavaScript code that can be used to reliably display the user's IP, whether in a form box or elsewhere on the page, by saving the IP in a variable. It requires that the page be Server Side Includes (SSI) enabled for the actual IP detection portion to work

<script language="JavaScript">
//IP address display: By http://www.Host
//     route.com
//Script featured on JavaScript Kit (htt
//     p://www.javascriptkit.com)
var ip = '<!--#echo var="REMOTE_ADDR"-->'
    function ipval() {
    document.myform.ipaddr.value=ip;
}

window.onload=ipval
</script>
<form method="post" action="" name="myform">
<input type="text" name="ipaddr" readonly>
</form>

Here's a demo of the script:

This is not javascript, it's SSI You can do the same with PHP instead of SSI: var ip = '<? echo $REMOTE_ADDR; ?>'
