[RESOLVED] switch case and operations within pages

ashley98860615

I'm making (well trying) to create a profile page for my user area. I have code to check whether the user is logged in, if they are they can proceed, if not they are chucked off...

That works fine but i am trying to use a switch statement to display different functions within the page (for example, password change-email-other details etc). The page loads fine but when i try to click my link to change the displayed content it does nothing. Here's my code:

check user logged in code....

function updatedetails () {
  //a html form
}

function start() {
  //welcome message
}

switch ($op) {
case "updatedetails":
updatedetails();
break;

default:
start();
break;

}

my link points to ./index.php?page=profile&op=updatedetails

Whats wrong with it?

Have you tried using $_GET['op'] instead of $op? Remember to check with isset() or empty() before use.

ah thanks it works now using the get function. not sure what you mean by the isset or empty though?

Well, they are used to check that particular incoming variables actually exist.
[man]isset/man
[man]empty/man

oh i see - so use them inside the function to make sure it's actually being called correctly. thanks
