How to send variables from a PHP script to another script using POST without forms?
I'm trying to write my first PHP script (hopefully). I want to send user input from a form inside an HTML page to a PHP script and validate them inside script. then, if there is any problem with input data, return to first page and highlight wrong fields. else go to another page (something like successful).

How do i send feedback from second script to first page without using forms?
