Create Thread from an external page

[rey maximo]

Hi everyone, I'm currently trying to find a workaround to be able to create threads from an external website. The website is on the same server but it has another domain name. I've found a code in this forum (I cannot find the url) for creating a thread from an external form in VB3. This server has VB4 installed, so I took it as a base to do some testing.

Here is the code for the test page (which is the code provided in the thread I mentioned adapted to my needs):

<?php

// ####################### SET PHP ENVIRONMENT ########################### 
error_reporting(E_ALL & ~E_NOTICE & ~8192); 

// Include vBulletin runtime files 
chdir("../../foro/foro");

require_once('./global.php'); 
require_once('./includes/functions_databuild.php'); 

/*
TEST - handle a new session
$newsession = new vB_Session($vbulletin, '', 0, '', $vbulletin->session->vars['styleid']);
$newsession->set('userid', 292);
$newsession->set('loggedin', 1);
$newsession->set_session_visibility(($vbulletin->superglobal_size['_COOKIE'] > 0));
$vbulletin->session =& $newsession;
*/



// Create a new datamanager for posting 
$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost'); 

// Set some variable and information 
$forumid = 81;                                                                  // The id of the forum we are posting to 
$userid = 292;                                                                  // The user id of the person posting 
$title = addslashes($_POST["titulo"]);                                           // The title of the thread 
$pagetext = addslashes($_POST["contenido"]);                                      // The content of the thread 
$allowsmilie = '1';                                                             // Are we allowing smilies in our post 
$visible = '1';                                                                 // If the post visible (ie, moderated or not) 

// Parse, retrieve and process the information we need to post 
$foruminfo = fetch_foruminfo($forumid); 
$threadinfo = array(); 
$user = htmlspecialchars_uni( fetch_userinfo($userid) ); 

$threaddm->set_info('forum', $foruminfo); 
$threaddm->set_info('thread', $threadinfo); 
$threaddm->setr('forumid', $forumid); 
$threaddm->setr('userid', $userid); 
$threaddm->setr('pagetext', $pagetext); 
$threaddm->setr('title', $title); 
$threaddm->set('allowsmilie', $allowsmilie); 
$threaddm->set('visible', $visible); 

// Lets see what happens if we save the page 
$threaddm->pre_save(); 
if(count($threaddm->errors) < 1) { 
    // Basically if the page will save without errors then let do it for real this time 
    $threadid = $threaddm->save(); 
    unset($threaddm); 
	echo "Posteado correctamente";
} else { 
    // There was errors in the practice run, so lets display them 
    var_dump ($threaddm->errors); 
	echo "Error";
} 
}
?>

This code takes the information from a form through POST method. When I run this script I get the following error:

Fatal error: Call to undefined method stdClass::set() in <route here>/includes/functions.php on line 7344.

The line which throws an error is the following in functions.php:

$vbulletin->session->set('inforum', (!empty($foruminfo['forumid']) ? $foruminfo['forumid'] : 0));

Now this error is because somehow the vB_Session class is not initialized or defined so PHP take it as an stdClass method (which is not), so I looked for a class definition file which was supposed to be called by global.php through its own required files and I found class_core.php which has the definition of the session class and its methods.

class_core.php is called before functions.php, which makes sense, but somehow it is not working, so I have no way to know if this code works or not.

Any ideas/suggestions?

Thanks in advance!

EDIT: Ok, after reading more threads and docs around there as I am outside of Vbulletin backend I need to define some constants first in order to make this work:

define('VB_AREA', 'External'); 
define('SKIP_SESSIONCREATE', 1); 
define('SKIP_USERINFO', 1);

It's not working yet but the class error doesn't appear anymore. (Now I get a "Unable to add cookies, header already sent." error), I'll keep trying until I can make this work. If anyone has an idea, please let me know. Thanks!.

Ok, I've managed to do it, here is the right code:

 

// Include vBulletin runtime files 
chdir("../../foro/foro"); // Move to where the forum is stored
require_once('./global.php');
require_once('./includes/functions_databuild.php'); 

//=============SET ENVIRONMENT======================
error_reporting(E_ALL & ~E_NOTICE & ~8192); 
define('VB_AREA', 'External'); 
define('SKIP_SESSIONCREATE', 1); 
define('SKIP_USERINFO', 1);

// Create a new datamanager for posting 
$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost'); 

// Set some variable and information 
$forumid = 81;                                                                  // The id of the forum we are posting to 
$userid = 292;                                                                  // The user id of the person posting 
$title = addslashes($_POST["titulo"]);                                           // The title of the thread 
$pagetext = addslashes($_POST["contenido"]);                                      // The content of the thread 
$allowsmilie = '1';                                                             // Are we allowing smilies in our post 
$visible = '1';                                                                 // If the post visible (ie, moderated or not) 

// Parse, retrieve and process the information we need to post 
$foruminfo = fetch_foruminfo($forumid); 
$threadinfo = array(); 
$user = htmlspecialchars_uni( fetch_userinfo($userid) ); 

$threaddm->set_info('forum', $foruminfo); 
$threaddm->set_info('thread', $threadinfo); 
$threaddm->set('forumid', $forumid); 
$threaddm->set('userid', $userid); 
$threaddm->set('pagetext', $pagetext); 
$threaddm->set('title', $title); 
$threaddm->set('allowsmilie', $allowsmilie); 
$threaddm->set('visible', $visible); 

// Lets see what happens if we save the page 
$threaddm->pre_save(); 
if(count($threaddm->errors) < 1) { 
    // Basically if the page will save without errors then let do it for real this time 
    $threadid = $threaddm->save(); 
    unset($threaddm); 
    echo "The thread was created succesfully";
} else { 
    // There was errors in the practice run, so lets display them 
    var_dump ($threaddm->errors); 
    echo "Error! The thread couldn't be created";
}

So basically the thing I was missing was to define the constants VB_AREA, SKIP_SESSIONCREATE and SKIP_USERINFO so I could bypass some VB checks. Now it's working great!

I leave this workaround for those who are interested. Hope it helps someone.

This was the thread I got the code from: https://vborg.vbsupport.ru/showthread.php?t=229654. Thanks megamoose for creating it! It probed to be really helpful.
