document.write as a variable

[dreamwest]

How can i store document.write as a variable

 

This outputs the country code "AU"

<script language="JavaScript">document.write(geoip_country_code());</script>

 

Now i need to use it in a php script

 

<?
$code =   ;//document.write output here

?>

so, since JavaScript is run client side, and PHP is server side, you can't directly use it. You need to send it back to the server, and for that you have a couple of options.

 

1) Do an AJAX call. If you are going to do this, I would suggest checking out jQuery...it will make your life way easier. Basically, you can submit data in the background.

 

2) If this is the only value you care about though, it's probably easier to just pass it in a resource call. The resource could be a CSS file, JS file, or an image. For example:

<script language="JavaScript">
  var img = new Image();
  img.src = 'geo_track.php?geo='+geoip_country_code();
</script>

The browser will request an image at that url, where you can have a PHP script to process the info, then sends back a 1 pixel blank image or just nothing at all
