[SOLVED] Array problems

[Skepsis]

I'm having problems with my permissions system. What I'm trying to add is a feature to add a user group.

 

When adding the group, we have checkboxes with certain fields that come from information that is stored in the $perms array.

 

First off, I'm trying to make it so when a checkbox is checked by the permission value, it is 1, if its not checked, the value is 0, that is already done.

 

When I post my form, the error I receive is:

 

Fatal error: Unsupported operand types in C:Program Filesxampphtdocslenixmodules  est.php on line 50

 

I have never even had that error before.

 

The $perms array looks like this:

<?php
$perms = array(    'forum' => array(
        1 => 'f_view',
        2 => 'f_post_topic',
        3 => 'f_post_reply',
        4 => 'f_attach',
        5 => 'f_manage_comment',
        6 => 'f_manage_cat',
        7 => 'f_moderator',
        8 => 'f_bypass_flood',
    ),    
    'users' => array(
        1 => 'u_view_users',
        2 => 'u_view_online',
        3 => 'u_view_profile',
        4 => 'u_manage_users',
        5 => 'u_manage_groups',
    ),
)    

// So how I display these is like this:

foreach($GLOBALS['perms'] as $permgroup => $perms )
{
    echo $permgroup.'<br>';

    foreach( $perms as $bit => $name )
    {
        echo '--'.$name.'<br>';
    }
}
?>

 

Notice this isn't the full html, I have certain code for the check boxes, but that's not important right now.

 

All that displays all fine and everything, the html is perfectly fine, getting the post data shouldn't be a problem.

 

This is where my code goes wrong:

 

<?php
// if any permissions were checked
if( $_POST['perms'] )
{
    // for all of the groups that had any checked boxes
    foreach($_POST['perms'] as $permgroup => $p)
    {
        // for each item checked in the bitfield
        foreach($p as $bit)
        {
            // add the bit to the permission group
            $perms[$permgroup] += $bit;
        }
    }
}

// the error is on this line of code:

// add the bit to the permission group
$perms[$permgroup] += $bit;
?>

 

Does anybody see anything out of the ordinary? I sure don't. This is why I'm asking for help, lol.

 

If anybody can point me in the right, or a better direction, that would be completely awesome, and I would be very thankful.

 

Thanks in advance.

show us the whole source of: C:Program Filesxampphtdocslenixmodules  est.php on line 50 but don't show us passwords etc, then we can better help you

When I post my form, the error I receive is:

 

Fatal error: Unsupported operand types in C:Program Filesxampphtdocslenixmodules  est.php on line 50

 

I have never even had that error before.

This is most probably because you're using double quotes for your include paths.

 

Either use single quotes

include 'C:\program files\xampp\htodcs\leniz\modules\test.php';

 

or use backslashes (/) instead of forward slashes (\) as the path seperater.

include "C:/program files/xampp/htodcs/leniz/modules/test.php";

[Skepsis]

The file being included is not a problem, I have a certain function that includes files in the modules/ folder, i've never had a problem with including the file.

 

Plus the error states that the error occurrs on line 50, which is:

<?php  $perms[$permgroup] += $bit; ?>

 

 

Here is a link of what the code is producing, you can do whatever you can try to add a group yourself.

And here is the source code:

            if(!$_POST['name']) $i = 1;

try this, otherwise I see nothing wrong >.>

You are awesome, this worked, thank you so much.

I didn't figure I'd have to define $perms as an array since it was already set.

 

Thanks again.
