I have created a code that will send an e-mail to someone and will embed a hidden 1x1px graphic. It records the email id into a database using MYSQL. When someone reads the email, it calls the bug.php file and adds a count to the database and displays the 1x1 image. In theory, if the count is greater than 0, the e-mail has been read (or at least displayed).
My question is this: is there any other method in which to do this? Currently, many e-mail apps by default do not open images in e-mails. therefore, the tracker only works if the image is automatically opened or is manually opened by the person if it is not opened by default.
I am new to PHP and am still trying to learn stuff. I am just trying to come up with my own little projects to learn the language and methods of design.
Any help?
