You may know that I'm working on a karma MOD that will eventually be two-sided, with an aspect of mod/admin-controlled karma and with an aspect of user-given karma not unlike a "thanks" MOD.
But I've hit a wall I can't seem to avoid nor tear down: I have a "functions_karpost.php" file, and I have code changes in "viewtopic.php", but they do not seem to work together.
I'm sure it's a stupid part of the functions file that's missing, but at the same time, I've based this code on the custom profile fields code (/include/functions_profile_fields.php and viewtopic.php)? So why it doesn't work is beyond me.
Here's the code I'm talking about:
- Code: Select all
<?php
class karma
{
function generate_karma_template($mode, &$row, $user_id = 0)
{
global $db, $user;
if ($mode == 'grab')
{
error_reporting(E_ALL);
$sql = 'SELECT *
FROM ' . USERS_TABLE . "
WHERE user_id = $user_id";
$result = $db->sql_query($sql);
$karma_data = array();
while ($ka_row = $db->sql_fetchrow($result))
{
$karma_data[$ka_row['karma']] = $ka_row;
}
$db->sql_freeresult($result);
return $ka_row['karma'];
}
else if ($mode == 'show')
{
$tpl_karma = array();
$tpl_karma['row'] = $tpl_karma['blockrow'] = array();
$karma_value = $this->get_karma($ka_row);
$tpl_karma['row'] = array(
'karma' => $karma_value,
'KARMA_NAME' => $user->lang['KARMA'],
);
$tpl_karma['blockrow'] = array(
'KARMA_FIELD_VALUE' => $karma_value,
'KARMA_NAME' => $user->lang['KARMA'],
);
return $tpl_karma;
}
else
{
trigger_error('Wrong mode for karma', E_USER_ERROR);
}
}
function get_karma(&$ka_row)
{
global $user;
$karma_value = $ka_row['karma'];
$positive_karmas = array

[?]
if (isset($cp_row['row']) && sizeof($cp_row['row']))
{
$postrow = array_merge($postrow, $cp_row['row']);
}
$postrow = array_merge($postrow, $tpl_karma['row']);
// Dump vars into template
$template->assign_block_vars('postrow', $postrow);
if (!empty($cp_row['blockrow']))
{
foreach ($cp_row['blockrow'] as $field_data)
{
$template->assign_block_vars('postrow.custom_fields', $field_data);

{
$template->assign_block_vars('postrow', array(
'KARMA_VALUE' => '100') // this part was intended as a test to see if it actually worked? which it didn't
);
}
}
And the problem is that viewtopic tells me that "tpl_karma" is an undefined variable. And on top of that, when I was using code closer to the custom profile fields code, it told me the same thing for $ka_row
So what's the problem exactly? Anyone with any ideas?
Well, I might as well say that young developers are often smarter
