multiple redirects based on login

Alright, I need some help on this. It's a bit more complicated than what I've done before and what I tried got me nowhere close (as in the process quit working....put the trash bin to good use!).

Anyways, what I need to do:

The system I has there are 4 different types of users. Referees, Assessors, Assignors, and Administrators. I have a login deal set up where users enter a user name and password and it opens their account. Currently I have 4 separate login areas for each type. However, I want to set it up so that there is one login screen, and it will automatically redirect to the proper area.

In my database I am storing, along with the users personal info, there are 3 columns 'assessor' 'assignor' and 'administrator. (There is no 'referee' column because that is the default and 95% of the people using the system are such). Those with "special" priviledges in the 3 classes above have a "yes" entered into the column for which they are granted access.

So basically I need to do something where, when they log in, it will match their user name and password to their user id (done), it will then look to see if a "yes" appears in the admin,assessor,or assignor columns. If so it will redirect to the corresponding page:

assignor: /assignor_login.php
admin: /admin_login.php
assessor: /assessor_login.php

If none of those apply, then it goes to the default referee area /referee_login.php

I assume its just a matter of several "if then else" type statements, but I'm unsure of how to do it.

Thanks for any help.

Use a switch not a series of if-elseif s. Faster, more flexible and easier to modify.

Instead of 3 columns just have 1 with user class.


switch (true) {
 case ($class == 'admin'):
     include 'admin.php';
     break;
 case ($class=='assessor'):
     include 'assessor.php';
     break;
  case ($class=='assignorr'):
     include 'assignor.php';
     break;
  default:
     include 'referee.php';
}

PS the way php implements a case select differs from other languages like C,Java, or VB, and is not as good or as fast when processing. It is one of the things that php falls down on, in my opinion. That said, it is a very powerfull construct in any language and always preferable to a series of if-elseif s.

'S alright. I wrote it the way I did so you could follow what was happening. Infact one would normally code it this way (but I have found problems with the followinf form)

switch ($class) {
 case 'admin':
     include 'admin.php';
     break;
 case 'assessor':
     include 'assessor.php';
     break;
 case 'assignor':
     include 'assignor.php';
     break;
 default:
     include 'referee.php';
}

Pay atention to the need for a BREAK; where you want processing to end for a particular case. PHP tumbles on down through the cases untill it encounters one. In VB it would stop at the next Case statement.

Thanks a lot Roger. It makes a lot of sense now that I know what the process is. I guess I was thinking of other programming languages with the if then stuff....but that works much nicer! 🙂

Thanks again!
