PHP Code:

if ($vbulletin->userinfo['field8']) 
{ 
    if ($vbulletin->options['globalignore']) 
    { 
        $vbulletin->options['globalignore'] = $vbulletin->options['globalignore'] . " " . $vbulletin->userinfo['field8']; 
    } 
    else 
    { 
        $vbulletin->options['globalignore'] = $vbulletin->userinfo['field8']; 
    } 
} 


Hi the above code was taken from a 3.5.4 hack but no longer works for 3.7.1, as you can see above its a very simple short code which presumably needs a few tweaks for it to work on a 3.7.1.

Field 8 you are seeing above is refering to a custom field which was created under each users profile.

I would really appreciate it if somebody could fix the above snippet for a 3.7.1,

Many thanks in advance!
