includes question

[adavis]

I am working on a script that displays a number of forms, and performs differing tasks depending on who is logging in:

• 1 - Login form
• 2 - Validate Login Form by reading mysql db
• 3 - Check password and if password is set to default value, make user change password
• 4 - Check db to see which pages the user can update and display appropriate links (includes
      • a - Display appropriate table for page update
      • b - View updates
      • c - If okay, write to database

Okay, so I'm using a case statement to control all of this. In #5, where I call an include of the appropriate page, I want to use another case statement to loop throug a number of pages in there.

My question: Will I stay inside the 2nd include case structure (a-c) until I tell it to return and how do I tell it to return???

Thanks,
Alisa

case structure?
Do you mean a switch statement?
Are you trying to loop using a switch?

include() is almost exactly the same as a function call.
When it reaches the end of the file, it returns to the calling page and continues executing.

You can stop execution in the current page and return to the calling page by calling return(); You can also pass a value using return(), so that in the calling page you can tell if it worked.

If you are still a bit confused, I suggest devising a simple test that gets at the concept of what you are doing.

the second include will just finish executing after its finished

include is like pulling a pieces of code into the namespace of your scripts. just be carefull not to overided variables that have the same name as in the calling script

for example

//action is submmitted as hidden
$action;
switch($form)
{ 
 .. . ..  .. . ..
    case '5':
        include('process.inc');
       //it would finish here after pulling the above code in

in process.inc

//make sure that you are not using the same or you will clobber the value
process_action = $action;
switch($process_action)
{
   . . . .  .. .. .
    case 'update':
    // do db , etc
}

if you were to use $action in process.inc and initialise it to null, things will obviously break

I'm sorry, yes, switch.

The two files--

index.php

switch($login) {
  case '1': include "login.inc";
  case '2': ...read database...;
  case '3': include $fileIN;   //(ex. menu.inc)
  case '4': make them change their password if it is set to defaultvalue;

}

[b]menu.inc[/b]
switch($menu) {
  case '1': display form;
  case '2': verify form;
  case '3': write to database;
}

I want to stay in menu.inc until I've forced an exit or it completes naturally.

I'm writing this in steps and have 1,2, & 4 working. I probably need to swap 3 & 4 though.

Thanks,
