PHP question about global variables and form requests
- by user220201
Hi,
This is probably a stupid question but will ask anyway sine I have no idea.
I have written basic php code which serve forms. Say I have a login page and I serve it using the login.php page and it will be called in the login.html page like this -
<form action="login.php" method="post">
By this it is also implied that every POST needs its own php file, doesn't it? This kind of feels weird. Is there a way to have a single file, say code.php, and just have each of the forms as functions instead?
EDIT: Specifically, say I have 5 forms that are used one after the other in my application. Say after login the user does A, B, C and D tasks each of which are sent to the server as a POST request. So instead of having A.php, B.php, C.php and D.php I would like to have a single code.php and have A(), B(), C() and D() as functions. Is there a way to do this?
Also on the same note, how do I deal with say a global array (e.g. an array of currently logged in users) across multiple forms? I want to do this without writing to a DB. I know its probably better to write to a DB and query but is it even possible to do it with a global array? The reason I was thinking about having all the form functions in one file is to use a global array.
Thanks,
