after login redirect to page according to user_level

after login redirect to page according to user_level

Hi

my apologies if this question has been covered previously but after trwaling cannot seem to locate the answer.

My question is: Is there an easy way to redirect a user after immediately logging in according to their user level access to their own specific page? ie a person logs in who has admin access redirects to for example admin-index.php or similarly a visitor with a visitor access level is immediately redirected to visitor-index.php ? I understand page level access but can't see the redirect anything other than the login success page.

is it something to do with parameters after clicking the folder browse button in the authenticate user login behaviour

Thanks in advance for help offered

you would need to hand code this on the login success page.

Lets say for exmple sakes that the session that contains the user level is named "UserLevel" and it contains the values "admin" or "visitor"

you could use the following code at line 1 of the login success page:

php:
<?php

if(!session_id()) session_start();
switch(
$_SESSION['UserLevel']) {
    case 
"admin":
        
header("Location: admin_index.php");
        break;
    case 
"visitor":
        
header("Location: visitor_index.php");
        break;
}
?>

That did it!

Hi Jason, thank you very much, that nailed it. I used your code and adapted:

<?php
if(!session_id()) session_start();
switch($_SESSION['user_level']) {
case "4":
header("Location: admin-index.php");
break;
case "3":
header("Location: admin-index.php");
break;
case "2":
header("Location: publishers-index.php");
break;
case "1":
header("Location: registered-index.php");
break;
}
?>

Makes me want to dive into php if I had more time!

without being presumptuous, you don't think it's something you might incorporate in a securityassist update?

will save as a snippet none the less

Thanks again

Russ

Can not modify the login PDP script

Hi Jason
I tried your login code to control different levels access, but after modifying the code as described a second "Log IN" server behavior is created and I receive a error message saying;
"The Server Behavior Panel can not determine whether "Log IN" or "Log In" is applied to your page. Please use Edit Server Behavior ... to ensure each is uniquely identifiable". But I can not edit them or delete any of the "log INs"?.
I get this message even I add a blank line in the automatically created code.
I am using CS5 Dreamweaver on vista.

I will appreciate any assistance. I took me two days continuous search to find this solution in this helpful forum

after login redirect to page according to user_level

Hi Jason
Here is my code for redirecting users to pages according to their level (userRole). I receive the following warning, when I browse:-
Notice: Undefined index: UserRole in C:\xampp\htdocs\Online_Site\Login.php on line 44

The "UserRole" is a column in users table in my mysql database.
The other code is created by dreamweaver. I just inserted your code with the modification according to my database
What can I do to make it work. I appreciate your assistance


mysql_select_db($database_MySQLonlineCoonetcion, $MySQLonlineCoonetcion);

you have a couple problems going on here.

1) At line 44 you are setting the $user variable to the value of the $_SESSION['userRole'] variable.

the error is saying that the $_SESSION['userRole'] variable does not exist. there is no where in the code that you are setting the userRole session variable.


2) The code to redirect the user based on user level needs to be applied to the login success page, not the login page.

3) you need to set the getCustomers recordset to filter the username
column on the $_SESSION['MM_Username'] value set by the login.

Then you can set the $_SESSION['userRole'] to use the value from the recordset.

Does not redirect

Thank you for response.
Since that day I was trying hard on re-direct my users after login according to their levels i.e "admin", "clerk", "client" and guest.
I checked the process by printing out before each steps and have the following result:
1a: UserName :admin01
1b: UserName :admin01
1c: UserRole :-admin
5: session statrted
7: LoginFormAction
13: isset($_POST[Username])= true
15: username: clerk01
17: Password:clerk01
18: UserRorle:clerk
Asign $MM_redirectLoginSuccess = getTheUserPage($UserRole)
19: Function getTheUserPage started
19b4switch: UserRole =clerk
19clerk: UserRole =clerk
19return UserRole:clerk
20: User LoginFounduser found
23: redirectLoginSuccess, call getUserPage

That shows my code was running but is not giving the required results as it is showing the user redirected page.
The code is as follows:
<? php

1) all of the echos before the header function will cause the header function to fail.


the header function cannot perform a redirect if there is outout to the page before the header function is called.

2) I see you are setting the $MM_redirectLoginSuccess variable in this code:
echo ('18: UserRorle:'.$UserRole.'<br> Asign $MM_redirectLoginSuccess = getTheUserPage($UserRole)'); //Result: clerk...
$MM_redirectLoginSuccess = getTheUserPage($UserRole); // User index Page


but none of your echo statements actually tell you what it is being set to by the time it hots this code:
header("Location: " . $MM_redirectLoginSuccess );


really, you only need one echo, just before the header function:
echo("redirect: ".$MM_redirectLoginSuccess);
header("Location: " . $MM_redirectLoginSuccess );

if that shows the correct URL, then delete the echo statement, and it should redirect you to the correct place.
