[SOLVED] error integrating mibbit

[M-4]

Greetings humans.

This unit is configuring a new phpBB3 board with mibbit.php: http://wiki.mibbit.com/index.php/PhpBB_integration#mibbit.php and in tests it throws this error:

Code: Select all

[phpBB Debug] PHP Notice: in file [ROOT]/mibbit.php on line 37: Undefined index: ircnick

A custom profile field was created via ACP for the IRC nickname (called ircnick, obviously).

Scanning functions_user.php (a mibbit.php include) and functions_profile_fields.php caused this unit's pseudo engrams to experience "a mass of conflicting impulses", as the unit Nomad would say (after that unit's unfortunate encounter with the unit Tan Ru, that is).
This unit cannot locate where 'ircnick' is or should be defined.

Mibbit loads error-free with the registered forum name in the login nick field if $userdata['username'] is used instead of $userdata['ircnick'].

Also, strangely, despite ACP settings to allow it, the IRC nick is not displayed in the post mini-profile block, but it is displayed in the main profile page. This unit's scans of HTML show no errors.

The db appears good.

This unit requires assistance and has contacted mibbit support, who were as clueless as M units 1-3.

This unit has reasoned it out.
A check of the db revealed that phpBB prepends "pf_" to the custom profile name specified in the ACP when it inserts it into the phpbb_profile_fields_data table as a new column.

Once this unit got the syntax correct in the $sql variable and replaced wiki's is_valid_nickname($userdata['irc_nickname']) ? $userdata['irc_nickname'] as shown below, it worked:

Code: Select all

// Begin mibbit      
// Grab IRC nick
   $sql = 'SELECT pf_mibbit FROM ' . PROFILE_FIELDS_DATA_TABLE . ' WHERE user_id = ' . $user->data['user_id'] . '';
   $result = $db->sql_query($sql);
   $nick = $db->sql_fetchfield('pf_mibbit');
   $db->sql_freeresult($result);
      
function is_valid_nick($nick)
{
   if($nick != '')
   {
      for($i = 0, $maxi = strlen($nick); $i < $maxi; $i++)
      {
         $code = ord($nick[$i]);
         if( !(($i > 0 && ( $code == 45 || ($code >= 48 && $code <= 57) )) || ($code >= 65 && $code <= 125)) ) break;
      }
      return ($i == $maxi);
   }
}

if($user->data['user_id'] != ANONYMOUS)
{
   $nick = is_valid_nick($nick) ? $nick : $user->data['username'];
}

else
{
   $nick = '';
}

if( !is_valid_nick($nick) )
{
   $nick = 'WebGuest_??';
}

$mibbit = 'http://widget.mibbit.com/?nick='.$nick
      .'&server=irc.anynet.org%3A6667'
      .'&noServerTab=false'
      .'&channel=%23anychan';

//Assign iframe src var
$template->assign_vars(array(
   'MIBBIT' => $mibbit,)
);
//End mibbit

The code above is in this unit's index.php because this unit has the mibbit iframe load automatically on initial site visit -- it is persistent, with the forum beneath it.
Ergo, in index.html:

Code: Select all

<div>
<iframe id="mibbit" class="mibbit" frameborder="0" width="95%" height="400" src="{MIBBIT}"></iframe>
</div>

Hope this proves useful...

Since mibbit loads automatically, a cookie will need to be created to fill the mibbit login field with a registered user's profiled IRC nick (or their forum name if the profile field is null). Guests get the default random treatment.
