Loading in extra data

Hey all, I've got a task to deal with ........ I'm integrating a XF board with a Facebook game and visa versa.

First step is that I need to get some data from the game database so I can use it in the message_user_info template (show the level & awards, give links to game profiles for admins etc).

So I need to get xf_user_external_auth.provider_key (the facebook ID) and then use that to get the player data from the game database.

Though where to load it in and how to grab the extra data ?

I'm all ears :)

Here is a quick hack to join xf_user_external_auth for posts:

library/XenForo/Model/Post.php

Add the red code:

Code:
	public function preparePostJoinOptions(array $fetchOptions)
	{
		$selectFields = '';
		$joinTables = '';

		$db = $this->_getDb();

		if (!empty($fetchOptions['join']))
		{
			if ($fetchOptions['join'] & self::FETCH_THREAD || $fetchOptions['join'] & self::FETCH_FORUM)
			{
				$selectFields .= ',
					thread.*, thread.user_id AS thread_user_id, thread.username AS thread_username,
					post.user_id, post.username, post.post_date'; // overwrite thread.post_date with post.post_date
				$joinTables .= '
					INNER JOIN xf_thread AS thread ON
						(thread.thread_id = post.thread_id)';
			}

			if ($fetchOptions['join'] & self::FETCH_FORUM)
			{
				$selectFields .= ',
					node.title AS node_title';
				$joinTables .= '
					INNER JOIN xf_node AS node ON
						(node.node_id = thread.node_id)';
			}

			if ($fetchOptions['join'] & self::FETCH_USER)
			{
				$selectFields .= ',
					user.*, IF(user.username IS NULL, post.username, user.username) AS username';
				$joinTables .= '
					LEFT JOIN xf_user AS user ON
						(user.user_id = post.user_id)';

				/* JOIN xf_user_external_auth */
				$selectFields .= ',
					user_external_auth.*';
				$joinTables .= '
					LEFT JOIN xf_user_external_auth AS user_external_auth ON
						(user_external_auth.user_id = post.user_id)';
				/* JOIN xf_user_external_auth */
			}

			if ($fetchOptions['join'] & self::FETCH_USER_PROFILE)
			{
				$selectFields .= ',
					user_profile.*';
				$joinTables .= '
					LEFT JOIN xf_user_profile AS user_profile ON
						(user_profile.user_id = post.user_id)';
			}

			if ($fetchOptions['join'] & self::FETCH_USER_OPTIONS)
			{
				$selectFields .= ',
					user_option.*';
				$joinTables .= '
					LEFT JOIN xf_user_option AS user_option ON
						(user_option.user_id = post.user_id)';
			}

			if ($fetchOptions['join'] & self::FETCH_DELETION_LOG)
			{
				$selectFields .= ',
					deletion_log.delete_date, deletion_log.delete_reason,
					deletion_log.delete_user_id, deletion_log.delete_username';
				$joinTables .= '
					LEFT JOIN xf_deletion_log AS deletion_log ON
						(deletion_log.content_type = \'post\' AND deletion_log.content_id = post.post_id)';
			}
		}

		if (!empty($fetchOptions['permissionCombinationId']))
		{
			$selectFields .= ',
				permission.cache_value AS node_permission_cache';
			$joinTables .= '
				LEFT JOIN xf_permission_cache_content AS permission
					ON (permission.permission_combination_id = ' . $db->quote($fetchOptions['permissionCombinationId']) . '
						AND permission.content_type = \'node\'
						AND permission.content_id = thread.node_id)';
		}

		if (isset($fetchOptions['likeUserId']))
		{
			if (empty($fetchOptions['likeUserId']))
			{
				$selectFields .= ',
					0 AS like_date';
			}
			else
			{
				$selectFields .= ',
					liked_content.like_date';
				$joinTables .= '
					LEFT JOIN xf_liked_content AS liked_content
						ON (liked_content.content_type = \'post\'
							AND liked_content.content_id = post.post_id
							AND liked_content.like_user_id = ' .$db->quote($fetchOptions['likeUserId']) . ')';
			}
		}

		return array(
			'selectFields' => $selectFields,
			'joinTables'   => $joinTables
		);
	}
Now this variable will work in the message_user_info template:

Code:
{$user.provider_key}
You can edit this file to use the provider_key to query your game database:

library/XenForo/ControllerPublic/Thread.php

Add the red code:

Code:
		$inlineModOptions = array();
		$maxPostDate = 0;
		$firstUnreadPostId = 0;

		$deletedPosts = 0;
		$moderatedPosts = 0;

		$pagePosition = 0;

		$permissions = $visitor->getNodePermissions($thread['node_id']);
		foreach ($posts AS &$post)
		{
			/* GET PLAYER DATA */
			if ($post['provider_key'])
			{
				// QUERY THE GAME DATABASE
			}
			/* GET PLAYER DATA */

			$post['position_on_page'] = ++$pagePosition;

			$postModOptions = $postModel->addInlineModOptionToPost(
				$post, $thread, $forum, $permissions
			);
			$inlineModOptions += $postModOptions;

			$post = $postModel->preparePost($post, $thread, $forum, $permissions);

			if ($post['post_date'] > $maxPostDate)
			{
				$maxPostDate = $post['post_date'];
			}
You probably don't want to query inside of a foreach, but you get the idea. ;)
