Pace, are you testing this on your localhost, or on the server itself?

You might have a much more successful time testing it on your localhost... it will show you the errors.
Watch out! I might do a code wheelie!

Until I last posted, it was only on the localhost, and that's where I got the blank page. So I decided to try on the server, and that's where I got error messages. Finally Tongue

But now I'm stuck with the error message I posted, the one concerning functions.php

Yes, post then entire function? it has to be added to the global for it to work.

Yeah, that is what I meant.
Very odd, $user is in the globals and it's giving you that error.
Though I guess you said you got past that? at least I hope.

Re: Karma.php problem?

Postby Pace » 15 Feb 2007, 12:45

Okay, Handyman inspired me, and after a few more hours of trying out new stuff, getting past one error and then past the next, I finally have a working karma.php
I now have one remaining problem: I can't get karma to show when someone looks at a user's profile.

I've been modifying memberlist.php, but it never seems to work.
What I need to put in there are the following bits of code:

Spoiler:
Code: Select all
        // Advanced KARMA Mod
        $sql = 'SELECT karma FROM ' . USERS_TABLE . " WHERE user_id= '$user_id' ";
        $result = $db->sql_query($sql);
        $karma = $db-> sql_fetchfield('karma');
        $db->sql_freeresult($result);
        $applaud_img = '';
        $applaud_alt = '';
        $applaud_url = '';
        $smite_img = '';
        $smite_alt = '';
        $smite_url = '';
        $user_karma = '';

        switch ($karma)
        {
            case -8:
            $karma_text = "Banned";
            break;
            case -7:
            $karma_text = "Galactic Scourge";
            break;
            case -6:
            $karma_text = "Public Enemy";
            break;
            case -5:
            $karma_text = "Most Wanted";
            break;
            case -4:
            $karma_text = "Fugitive";
            break;
            case -3:
            $karma_text = "Felon";
            break;
            case -2:
            $karma_text = "Criminal";
            break;
            case -1:
            $karma_text = "Offender";
            break;
            case 0:
            $karma_text = "Clean";
            break;
            case 1:
            $karma_text = "Decent Individual";
            break;
            case 2:
            $karma_text = "Good Egg";
            break;
            case 3:
            $karma_text = "Upstanding Citizen";
            break;
            case 4:
            $karma_text = "Role Model";
            break;
            case 5:
            $karma_text = "Pillar of Society";
            break;
            case 6:
            case 7:
            $karma_text = "Honoured Leader";
            break;
            case 8:
            $karma_text = "Divine";
            break;
        }

        if ($user_id == 2)
        {
            $user_karma = $user->lang['KARMA'] . ': Divine (n<sup>n</sup>)';
        }
        else
        {
            if(!$auth->acl_gets('a_', 'm_') && !$auth->acl_getf_global('m_'))
            {
                $user_karma = $user->lang['KARMA'] . ': ' . $karma_text . " ($karma)";
            }
            else
            {
            $applaud_alt = $user->lang['APPLAUD'];
            $applaud_url = append_sid("{$phpbb_root_path}karma.$phpEx?" . "&amp;u=$user_id&x=applaud");
            $applaud_img = '<img src="styles/Galarpian/imageset/icon_applaud.gif" width="11" height="11" border="0" />';
            
            $user_karma = $user->lang['KARMA'] . ': ' . $karma_text . " ($karma)";

            $smite_alt = $user->lang['SMITE'];
            $smite_url = append_sid("{$phpbb_root_path}karma.$phpEx?" . "&amp;u=$user_id&x=smite");
            $smite_img = '<img src="styles/Galarpian/imageset/icon_smite.gif" width="11" height="11" border="0" />';
            }
        }
        
        // Advanced KARMA Mod

When posted in the function "show_profile($data)
{" area, this gives me an error: "undefined variable: db".
Now, why does it do that? The "$db->" is used in plenty of other places.
If, on the other hand, I post it in the "case 'viewprofile':" section, well, it doesn't work either, because the page then tells me the "$user_karma" variable is not defined.

After that, I have to put the following:
Code: Select all
'USER_KARMA' => $user_karma,

Now, it seems I'm supposed to put that in the
Code: Select all
    // Dump it out to the template
    return array(

part, but I'm not sure, due to all the errors I get?

So, what's the problem now?

Re: Karma.php problem?

Postby Highway of Life » 15 Feb 2007, 14:49

OH boy... lots of changes here...
Let me see if I can quickly address the biggest issues...
  1. first NEVER hardcode language into your php public file.
    Hmm... I shall repeat that...

    NEVER put language variables outside of your language directory.
  2. Second, all the data from the users table is already being called, so we don?t need ANOTHER query...
  3. Third, you would probably want to control the karma levels from the language file, see code opimization below.
  4. Fourth, Empty defined variables can be defined in one line of code, i.e.
    Code: Select all
    $variable = $another_var = $yet_another = $still_more = $im_empty_too = '';
  5. Fifth, you?ll want to include this code in a seperate file, then call it through a function, see code optimization below.
  6. Sixth, allow for greater values than -8 to +8, as it?s currently only a span of 16 clicks, so it would only take a handful of posts to reach those numbers.
    Idealy, you would want to manage this from the ACP, but for a very simple, generic karma system such as this, you can control it through the language.
  7. Seventh, Don?t use a static User ID for the founder, use a user type instead... see code optimization below.
  8. Eighth, See example of how to return the variables for use in the template, again, if it?s more than a small handful of lines of code, you?ll want to include a karma template file into the memberlist_view and memberlist_body files.
I?ll stop there since that is quite a lot, give this a shot, and go from here.

First, to the memberlist.php file...
Code: Select all
*** /phpBB3/memberlist.php   Wed Feb  7 20:47:30 2007
--- /phpBB3/memberlist_new.php      Thu Feb 15 14:37:03 2007
***************
*** 488,493 ****
--- 488,496 ----
                        unset($module);
                }
  
+               include_once($phpbb_root_path . 'includes/functions_karma.' . $phpEx);
+               grab_karma_rank($member['user_karma'], $member['user_type']);
+ 
                $template->assign_vars(array(
                        'POSTS_DAY'                     => sprintf($user->lang['POST_DAY'], $posts_per_day),
                        'POSTS_PCT'                     => sprintf($user->lang['POST_PCT'], $percentage),

Then, in the functions_karma.php file...

Code: Select all
<?php
function grab_karma_rank($user_karma, $user_level)
{
    global $user, $template;
    // when we expand this mod for ACP and database control,
    // we would probably use regular expressions to determine the values,
    // but for now, we can be somewhat static.
    $i = $user_karma;
    switch ($i)
    {
        case ($i <= 0):
            $karma = $user->lang['karma_negative'][0]; // this would be clean.
        break;
        case ($i <= -1):
            $karma = $user->lang['karma_negative'][1];
        break;
        case ($i <= -3):
            $karma = $user->lang['karma_negative'][2];
        break;
        // ... repeat until you reach something close to like -20
        // which would be "banned"
        // then start on the positive case...
        case ($i => 1):
            $karma = $user->lang['karma_positive'][0];
        break;
        case ($i => 5):
            $karma = $user->lang['karma_positive'][1];
        break;
        case ($i => 12):
            $karma = $user->lang['karma_positive'][2];
        break;
        // etc... and repeat until you reach something like oh... 100 or so
        // which would be Supreme Ruler, or some such thing
    }
    
    if ($user_level == USER_FOUNDER)
    {
        $karma = $user->lang['karma_positive'][20]; // assuming 20 is "Divine"
    }
    
    $template->assign_vars(array(
        'KARMA_LEVEL'    => $karma,
    ));
    
    return;
}

?>


Your language file would contain something like:
Code: Select all
<?php
// ... header info
$lang = array_merge($lang, array(
    'karma_negative' => array(
        'Clean',
        'Offender',
        'Criminal',
        'Felon', // etc...
    ),
    
    'karma_positive' => array(
        'Decent Individual',
        'Good Egg',
        'Upstanding Citizen',
        'Role Model', // etc...
    ),
?>


Remember, these are just examples... change to fit..
And I?m thinking there must be a better way to handle the level switch...

Scratch

Ah, like the Ranks, but those are database controlled, still might glean an idea off of that system.

Re: Simple Karma Challenge

Heh? Okay, I'll look at that tomorrow. Thanks for explaining that. I was really only porting the old karma hack.

Anyway, once I've got everything working, I'll put that together as a MOD, and post the code of my karma.php file here as well.

Thanks again!
