Google Conversion Tracking

[amain]

How do I set-up the subscription form so it works with the Conversion Tracking feature from Google Adwords

You will need to create an image that you're going to use in the newsletter. Most often a 1x1 pixel image will do the job.  Don't use a background image though as this won't always get through.

You'll need to change or create an .htaccess file. in the directory where the image is. I use something like this

Code:

RewriteEngine On
RewriteRule ^(.*).jpg image.php?$0 [L]

Now for image.php

Code:

<?php

$var_utmac='UA-XXXXXXXX-1'; //enter the new urchin code
$var_utmhn='yourdomain.com'; //enter your domain
$var_utmn=rand(1000000000,9999999999); //random request number
$var_cookie=rand(10000000,99999999); //random cookie number
$var_random=rand(1000000000,2147483647); //number under 2147483647
$var_today=time(); //today
$var_referer=$_SERVER['HTTP_REFERER']; //referer url

$var_utmcsr='ContactManager';  // the campaign source
$var_utmcmd='email';  // the campaign medium
$var_utmccn=$_SERVER['argv'][0];  // the campaign name

$var_uservar='-'; //enter your own user defined variable
$var_utmp='tracker/'.$_GET['url'].'.'.$_GET['filetype']; //this example adds a fake file request to the (fake) tracker directory (the image/pdf filename).

$urchinUrl='http://www.google-analytics.com/__utm.gif?utmwv=1&utmn='.$var_utmn.'&utmsr=-&utmsc=-&utmul=-&utmje=0&utmfl=-&utmdt=-&utmhn='.$var_utmhn.'&utmr='.$var_referer.'&utmp='.$var_utmp.'&utmac='.$var_utmac.'&utmcc=__utma%3D'.$var_cookie.'.'.$var_random.'.'.$var_today.'.'.$var_today.'.'.$var_today.'.2%3B%2B__utmb%3D'.$var_cookie.'%3B%2B__utmc%3D'.$var_cookie.'%3B%2B__utmz%3D'.$var_cookie.'.'.$var_today.'.2.2.utmccn%3D('.$var_utmccn.')%7Cutmcsr%3D('.$var_utmcsr.')%7Cutmcmd%3D('.$var_utmcmd.')%3B%2B__utmv%3D'.$var_cookie.'.'.$var_uservar.'%3B';

$handle = fopen ($urchinUrl, "r");
$test = fgets($handle);
fclose($handle);

$showit = $_GET['url'].'.'.$_GET['filetype']; //this is where the real file should be located

$filename = $_SERVER['argv'][0];
header('Content-Type: image/jpeg');

$imageurl = fopen($filename, "r"); //this is where the real file should be located

while (!feof ($imageurl)) 
{
$image = fgets($imageurl, 4096);
echo $image;
}
fclose($imageurl);

?>

Post Merge: March 12, 2010, 09:35:54 PMSome servers, and one of my providers does this, don't allow you to fopen a URL, in which case the work around is to create a function at the top of the code as follows:

Code:

function get_content($url)
{
    $ch = curl_init();

    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_HEADER, 0);

    ob_start();

    curl_exec ($ch);
    curl_close ($ch);
    $string = ob_get_contents();

    ob_end_clean();
   
    return $string;   
}

and replace

Code:

$handle = fopen ($urchinUrl, "r");
$test = fgets($handle);
fclose($handle);

with 

Code:

$test = get_content($urchinUrl);
