How I can track unique emails I sent using PHP and GD ?
Basically I have function where I'm saving into DB stats (file - script.php) and the using GD2 imagecreate() imagepng() I'm creating image - data collection works fine, but making situation more complicated - I want to track some part of emails, so I want to put there some unique ID - and now the question :
I have following code - <img src="script.php" alt="" /> .... now I want to add something like: <img src="script.php?id=22" alt="" /> - and question is how to get ID - it's not a POST or GET - s what is it ?
Maybe there is no solution, and you have some other ideas/ways how I can do it ? Or maybe you have some simple JS solution ?
