what does shutdown_query do?

PHP Code:


		
			
$DB_site->shutdown_query("

just wondering what this does as opposed to ->query_first and ->query

PHP Code:


		
			
    function shutdown_query($query_string, $arraykey = 0)

    {

        global $shutdownqueries;



        if (NOSHUTDOWNFUNC AND !$arraykey)

        {

            return $this->query($query_string);

        }

        elseif ($arraykey)

        {

            $shutdownqueries["$arraykey"] = $query_string;

        }

        else

        {

            $shutdownqueries[] = $query_string;

        }

    }

that went right over my head.

let's simplify

->query( // you'd use for a loop
->query_first( // standard query
->shutdown_query( // ???

You know what, I have absolutely no idea. It appears that it's a feature designed to run queries after the page has rendered. All the queries in shutdown queries are not run at that particular part of the script I can tell you that. If you look at exec_shut_down() in functions.php you'll see what happens. However, I can't find any reference to that function being run anywhere in any of the vB files :)

Who knows... maybe I'm overlooking something

Lol, you should read the how-to's :D

With great thanks to Bruce.Lee :D :D

I just checked again, and that function is not being called anywhere according to ultraedit!

And I thought UltraEdit was a good software ^.^

admincp/global.php

PHP Code:


		
			
    if (!empty($cpsession))

    {

        $DB_site->shutdown_query("

            UPDATE LOW_PRIORITY " . TABLE_PREFIX . "cpsession

            SET dateline = " . TIMENOW . "

            WHERE userid = $bbuserinfo[userid]

                AND hash = '" . addslashes($_COOKIE[COOKIE_PREFIX . 'cpsession']) . "'

        ");

announcement.php

PHP Code:


		
			
if ($anncids)

{

    $DB_site->shutdown_query("

        UPDATE " . TABLE_PREFIX . "announcement

        SET views = views + 1

        WHERE announcementid IN ($anncids)

    ");

}

attachment.php

PHP Code:


		
			
        // doing it as they happen

        $DB_site->shutdown_query("

            UPDATE " . TABLE_PREFIX . "attachment

            SET counter = counter + 1

            WHERE attachmentid = $attachmentinfo[attachmentid]

        ");

and so on.

Or did you mean exec_shut_down?

functions.php

PHP Code:


		
			
if (!NOSHUTDOWNFUNC)

{

    register_shutdown_function('exec_shut_down');

}

PHP Code:


		
			
    if (NOSHUTDOWNFUNC)

    {

        exec_shut_down();

    }

No no no no.... ;)

Ok those queries are passed to the method with db_mysql.php, and either ran at that exact time or stored in an array. This array is then released by the method with a global call and acn be used anywhere else in the script. There is then no reference to where-else these queries are ran. So they must be run at that exact point in the script. Do a search for $shutdownqueries and you tell me where they are run, in exec_shut_down. Ok then tell me where this function is ran ;)

Follow?

Revised my last post to include the references for exec_shut_down

Weird I don't have those lines in my functions.php?
