Code to post new thread

[squishi]

I've copied the part of newthread php in a plugin, but it is not working.
What am I missing?
The code is run in the hook "private_start".

PHP Code:

if ($_POST['sent'] == '1') {

//##################
//post a new thread!

//require_once('./global.php');
require_once(DIR . '/includes/functions_newpost.php');
//require_once(DIR . '/includes/functions_editor.php');
//require_once(DIR . '/includes/functions_bigthree.php');

    $checked = array();
    $newpost = array();
    $postattach = array();

    // Variables reused in templates

    $foruminfo = array();
    $foruminfo['forumid'] = 78; // The new thread should be posted in forum no. 78.

    $posthash = $vbulletin->input->clean_gpc('p', 'posthash', TYPE_NOHTML);
    $poststarttime = $vbulletin->input->clean_gpc('p', 'poststarttime', TYPE_UINT);

    $vbulletin->input->clean_array_gpc('p', array(
        'wysiwyg'         => TYPE_BOOL,
        'preview'         => TYPE_STR,
        'message'         => TYPE_STR,
        'subject'         => TYPE_STR,
        'iconid'          => TYPE_UINT,

        'signature'       => TYPE_BOOL,
        'disablesmilies'  => TYPE_BOOL,
        'parseurl'        => TYPE_BOOL,

        'username'        => TYPE_STR,
        'loggedinuser'    => TYPE_INT,
    ));

    if ($vbulletin->GPC['loggedinuser'] != 0 AND $vbulletin->userinfo['userid'] == 0)
    {
        // User was logged in when writing post but isn't now. If we got this
        // Force them to log back in.
        standard_error(fetch_error('session_timed_out_login'), '', false, 'STANDARD_ERROR_LOGIN');
    }

    if ($vbulletin->GPC['wysiwyg'])
    {
        require_once(DIR . '/includes/functions_wysiwyg.php');
        $newpost['message'] = convert_wysiwyg_html_to_bbcode($vbulletin->GPC['message'], $foruminfo['allowhtml']);
    }
    else
    {
        $newpost['message'] =& $vbulletin->GPC['message'];
    }

    $vbulletin->GPC['postpoll'] = false;

    $newpost['title'] =& $vbulletin->GPC['subject'];
    $newpost['iconid'] =& $vbulletin->GPC['iconid'];

    $newpost['parseurl']        = (($vbulletin->options['allowedbbcodes'] & ALLOW_BBCODE_URL) AND $foruminfo['allowbbcode'] AND $vbulletin->GPC['parseurl']);
    $newpost['signature']       =& $vbulletin->GPC['signature'];
    $newpost['preview']         =& $vbulletin->GPC['preview'];
    $newpost['disablesmilies']  =& $vbulletin->GPC['disablesmilies'];
    $newpost['username']        =& $vbulletin->GPC['username'];
    $newpost['folderid']        =& $vbulletin->GPC['folderid'];
    $newpost['humanverify']     =& $vbulletin->GPC['humanverify'];
    $newpost['poststarttime']   = $poststarttime;
    $newpost['posthash']        = $posthash;

    $newpost['emailupdate'] = 0;

    build_new_post('thread', $foruminfo, array(), array(), $newpost, $errors);

    if (sizeof($errors) > 0)
    {
        // ### POST HAS ERRORS ###
        $postpreview = construct_errors($errors); // this will take the preview's place
        construct_checkboxes($newpost);
        $newpost['message'] = htmlspecialchars_uni($newpost['message']);
    }
    else
    {
        // ### NOT PREVIEW - ACTUAL POST ###
        $threadinfo = fetch_threadinfo($newpost['threadid']); // need the forumread variable from this
        mark_thread_read($threadinfo, $foruminfo, $vbulletin->userinfo['userid'], TIMENOW);

    } // end if

$vbulletin->url = 'forumdisplay.php?' . $vbulletin->session->vars['sessionurl'] . "f=$foruminfo[forumid]";
            eval(print_standard_redirect('redirect_accountdeletion_message', true, true));

//####################

$_POST['sent'] is '1'. I set this in a custom form. The new private message is sent, but no thread is created.

I know there's probably a lot of useless code in there. But I would like to first get it to work before I weed out the unnecessary stuff.

I also have a problem with the redirect message. See here: https://vborg.vbsupport.ru/showthread.php?t=213457
