making code run when something pressed

[Anon]

How do I make php go to a certain place in code, go to a function etc when something is pressed... I will use this for a login system. I have the login script done, but I need it to run when a button is pressed. Either a link or a form button, etc...

create a form and put the php script you want to process it in the action tag:
<form action="form.php">
