I'm trying to get the scripts to work well with updates. Basically, when a person checks for updates on his site just in case there's new updated scritps available, it modifies the $_POST['update'] to a yes or no so it returns to the site and tells it instead of showing my site ever coming up.

I want it just like a program that checks for updates and if there's a new updates, it doesn't go straight to the site, it tells you on the program.

Do you know how to modify a $_POST?
omg. y'all are dumb. I'm trying to make it so there is a form on their site that they bought scripts from me. When they click on a button, to sends information to a page on my site and modifies the $_POST function while transferring back to their site and not showing mine and the $_POST function will be renamed so the update page on their site would tell the scripts what to say.

it's a simple check for updates.
