need to add usercp content

[moonlightcheese]

i need to add an extra nav option in the usercp and add an additional page for changing user options, which i've added as a table to the database.

i'm assuming i need to change the USER_SHELL template and add some code to profile.php for the additional page... right? what's up with all the $navclass stuff and $session and $vbphrase? do i need to add the info for the new page to an include file somewhere?

i'm completely unfamiliar with vbb... but well-versed in php+mysql.

i got as far as editing a few things in the USER_SHELL template and some other stuffs. here's a post i made at vbulletin.org... they refered me here since they don't officially work with code modifications.

didn't know where else to ask these questions... i've asked a lot of questions about vbb over the last couple months and got no answers and a bunch of redirections. hope someone here can answer...

i've been working on adding a little plugin to vbb for folding stats. when i added this code to USERCP_SHELL:

<tr>
    <td class="$navclass[profile]" nowrap="nowrap"><a class="smallfont" href="profile.php?$session[sessionurl]do=editprofile">$vbphrase[edit_profile]</a></td>
</tr>
<tr>
    <td class="$navclass[folding]" nowrap="nowrap"><a class="smallfont" href="profile.php?$session[sessionurl]do=editfah">$vbphrase[edit_fah]Edit F@H Profile</a></td>
</tr>
<tr>
    <td class="$navclass[options]" nowrap="nowrap"><a class="smallfont" href="profile.php?$session[sessionurl]do=editoptions">$vbphrase[edit_options]</a></td>
</tr>

i get this:


and the pretty baby blue CSS is missing. whats up with that?

since the $vbphrase that i added doesn't populate correctly, i just added the text in next to the variable. how can i get the $vbphrase variable to work? i tried to add the $vbphrase with:

$phrase = construct_phrase($vbphrase["edit_fah"], "Edit F@H Profile");

    $cells = array(
        'usercp',

        'signature',
        'profile',
        'options',
        'password',
        'avatar',
        'profilepic',
        'folding',

        'pm_messagelist',
        'pm_newpm',
        'pm_trackpm',
        'pm_editfolders',

        'substhreads_listthreads',
        'substhreads_editfolders',

        'deletedthreads',
        'deletedposts',
        'moderatedthreads',
        'moderatedposts',

        'event_reminders',
        'paid_subscriptions',
        'usergroups',
        'buddylist',
        'attachments'
    );

how can i define the 'folding' navclass properly. apparently something is wrong.
