Array Help

[Skepsis]

Okay, so let me explain what i'm trying to do.

I'm creating a permission system for my cms

 

I have the permissions defined inside my config.php folder.

The defined permissions looks like this:

 

<?php
$permissions = array(
    'faq' => array(
        1 => 'f_view',
        2 => 'f_manage',
        4 => 'f_ask',
    ),
    'page' => array(
        1 => 'p_view',
        2 => 'p_manage_cat',
        4 => 'p_manage_comment',
        8 => 'p_post_page',
        16 => 'p_post_comment',
    ),
    'bug' => array(
        1 => 'b_view',
        2 => 'b_manage_cat',
        4 => 'b_manage_comment',
        8 => 'b_post_issue',
        16 => 'b_post_comment',
    )
)
?>

 

When creating a user group, these permission groups(faq,page,bug) have bitfields, such as(b_manage_cat,b_manage_comment).

 

When you check a box, it sets the bitfields value as true, unchecked, its false.

It then serializes the array, and puts it inside the perms field inside the groups table.

 

I have a screen shot attached to this post of what my $_SESSION global contains, below it, is the unserialized content of the perms group contains.

 

What I want to do, is add the unserialized array into the perms session data.

 

But what I am having trouble with, is that itself.

 

This is the code I use, to set the set the perm groups into the session(which is currently not working).

 

<?php
    // for all the permission groups
    foreach( $permissions as $permgroup => $perms )
    {
        // for each item in the bitfield
        foreach( $perms as $bit => $name )
        {
            // if the bit is set for this permission in their usergroup
            if( $user_group[$ugid]['perms'][$permgroup] & $bit )
            {
                // set this permission to true
                $_SESSION["$security_session"]['perms'][$permgroup][$name] = true;
            }
        }
    }
?>

 

What I want, if the permission name is in the unserialized array, and it has the bitfield, you set it to TRUE, but I can't even get to perms to go inside my array.

 

Thanks for any help in advance.

1.) Do you have session_start at the top of your page?

 

2.) Do you have all errors turned on and display errors on? If you're not sure, add these to the top of your script:

 

ini_set('display_errors','On');
error_reporting(E_ALL);

[Skepsis]

Yes,session_start has been initiated.

Error reporting is on E_ALL, there are no errors.

 

let me post the actual function i'm using:

<?php
function fetch_perms($ugid)
{
  global $user_group,$permissions,$security_session;
  
    // for all the permission groups
    foreach( $permissions as $permgroup => $perms )
    {
        // for each item in the bitfield
        foreach( $perms as $bit => $name )
        {
            // if the bit is set for this permission in their usergroup
            if( $user_group[$ugid]['perms'][$permgroup] & $bit )
            {
                // set this permission to true
                $_SESSION["$security_session"]['perms'][$permgroup][$name] = true;
            }
        }
    }
}
?>

        )

)

okay, so what im trying to do, is be able to do this,

if ($_SESSION['perms']['forums'][f_can_view] == TRUE)

{ do this }

 

but i might first assign the perms to the session properly

which is what im stuck doing

can i have a bump since my topic got knocked down to the end of the list?
