Need to Chose a Threadid at start of file.

[Michael Morris]

I'm working on a hack and I trying to add a feature that will allow users to call up threads from a certain thread by their name. To do this I need to recall the threadid.

Now, the $featsname variable by this point in the code has been ran through the globalize function lest hackers get any ideas. Here's de code..

// Determine our thread id by feat name.

PHP Code:

// Determine our thread id by feat name.
if (!empty($featname))
{
    // We are searching by name rather than thread id.  We'll check permissions later,
    // for now just query up the first occurance of the featname.
    $threadcache = query_first("
            SELECT threadid
            FROM " . TABLE_PREFIX . "feats
            LEFT JOIN " . TABLE_PREFIX . "thread AS thread ON(thread.threadid = feats.threadid)
            WHERE thread.title = '" . addslashes($featname) . "'
            ");
    
    $threadid = $threadcache['threadid'];
} 

But this doesn't fetch the thread. What do I need to do?

EDIT: Just to be clear, my feats table has threadid as a foreign key so that it can be joined to the thread table. I presume that joining the thread table to it will drop the rows that don't occur on both tables.

Nevermind, found my problem - needed to call the function fetch_threadinfo. For the curious, final code:

PHP Code:

// Determine our thread id by feat name.
if (!empty($featname))
{
    // We are searching by name rather than thread id.  We'll check permissions later,
    // for now just query up the first occurance of the featname.
    $featthread = $DB_site->query_first("
            SELECT feats.threadid AS threadid
            FROM " . TABLE_PREFIX . "feats
            LEFT JOIN " . TABLE_PREFIX . "thread AS thread ON(thread.threadid = feats.threadid)
            WHERE thread.title = '" . addslashes($featname) . "'
            ");
    $threadid = $featthread['threadid'];
    
    // Fetch it
    fetch_threadinfo(&$threadid);
}
