Hi, I have a script which I plan on selling. I do not wish to encode or use anything like zend or php licensing script etc but I want to protect let's say 1 page like admin section etc. I need to place some code in admin area let's say header or login.php file which code should send me an email first time it is launched so I know what domain the script was installed at. I can then add that domain to my database if I know I sold this script to this guy. The script works behind the scene so user should not know that we have knowledge of the installation location. it should work 2 times and if 3rd time there's no license domain in our database, it takes them to our page where we can ask them to provide payment details to get license. This is what I'm thinking but you might have a better and easier solution for me...or maybe you have already developed something similar. If you can do this, please let me know how much will this cost me. Looking forward to hearing from someone soon.
it's hard to make something like this, and you need to garantee that your license server will be always up!!! better way is to work with keys based on there IP adres and hostname or something
