Little code confusion

May 15th, 2008

After logging in, main.php is loaded and instead of displaying the correct included page, it displays Main Page.

So what is wrong w/ my code?

Thanks in advance for any and all help...

this is placed inside the "main.php"

<?php 
    require('core/db.php');
    require('core/check.php');
?>
  
This is placed inside the check.php

<?php
    if (level == "1")  { include('page_1.php'); } 
     else 
    if (level == "2") { include('page_2.php'); }
     else 
    if (level == "3") { include('page_3.php'); }
?>   
Inside the pages I have 
<?php 
   echo "Page_Name";
?>

else
if (level == "3") { include('page_3.php'); }

Shouldn't level be $level ?

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

nav33n,
Yea, I changed level to $level, but it still didn't change anything. I am unsure what else needs to be changed as far as the login form is concerned.

Here is the code for everything I have:

Also, in check.php, don't forget to assign $_SESSION['level'] value to $level.

Now it works, it just displays page_1.php for all users logging in.

$_SESSION["level"] = 1; 
$_SESSION["level"] = 2;
$_SESSION["level"] = 3;


check.php source:

  if ($level = "1") { 
   include('page_1.php');  } 
   else 
  if ($level = "2") { include('page_2.php'); }

   else 
  if ($level = "3") { include('page_3.php'); }
?>

Its $level == "1" and so on.. And why not use just if conditions ? ie.,

$level = $_SESSION['level'];
if ($level == "1") {
  include "page_1.php";
}
if($level == "2") {

} 
//and so on.. 
$level = $_SESSION['level'];
if ($level == "1") {
  include "page_1.php";
}
if($level == "2") {
  include "Page_2.php";
} 
//and so on..

Nav33n,
I have tried to the code in every which way possible. Nothing I do works correctly.
All I get is page_1.php to load no matter what.

Here is the code that I have now...

index.php

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
$level = $_SESSION['level'];
$_SESSION["level"] = 1;
$_SESSION["level"] = 2;
$_SESSION["level"] = 3;
$level = $_SESSION['level'];
$_SESSION["level"] = 1;
$_SESSION["level"] = 2;
$_SESSION["level"] = 3;

check.php

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
$level = $_SESSION['level'];
if ($level == "1") {  include "page_1.php"; }
else
if ($level == "2") {  include "page_2.php"; }
else
if ($level == "3") {  include "page_3.php"; }
?>
<?php
$level = $_SESSION['level'];
if ($level == "1") {  include "page_1.php"; }
else
if ($level == "2") {  include "page_2.php"; }
else
if ($level == "3") {  include "page_3.php"; }
?>

This displays nothing.
When I change it to:

 Help with Code Tags 
 php Syntax (Toggle Plain Text) 
<?php
if ($level = "1") {  include "page_1.php"; }
else
if ($level = "2") {  include "page_2.php"; }
else
if ($level = "3") {  include "page_3.php"; }
?>
<?php
if ($level = "1") {  include "page_1.php"; }
else
if ($level = "2") {  include "page_2.php"; }
else
if ($level = "3") {  include "page_3.php"; }
?>

This will display page_1 no matter what the level is...
Please excuse my ignorance. Thanks for any and all help.

$level = 1 isn't correct. Since you are comparing the value of $level, you need to use comparison operator. http://nl.php.net/operators.comparison
Secondly, where are you assigning the value to $_SESSION['level'] ? I think the value is being overwritten or something. Btw, there is no session_start() in check.php. When you assign the value to the session variable, check whats in it. In check.php, check print out the session variable value and cross check !
