I have the CZUserinfo block with a few small tweaks to accommodate our subscription model on our site (It does a single query to find the database to get subscription status for each user)

Now I am no SQL Expert so not sure if our extra query line is the issue or whether it is the way the block operates but..

I just noticed our front page had almost 300 queries to produce, we had about 150 members online at the time, i temporarily disabled the cz user info block and the queries dropped down to 140 !!!

would the number of queries increase so high due to the number of members online (I note that the number of queries to produce the front page increases vs the number of members online at the time)

So for each user online it does a query for the status of thier subscription?

Then 150 people online equals an extra 150 queries.

Best bet is to write a JOIN statement for the subscription table and the online table so it runs as one query.

Post the query for the online users and the query your using to get the subscription.

thx for the offer of help

your query is as follows:-

SELECT w.uname, u.user_id, u.user_level, u.user_rank, u.user_allow_viewonline FROM ".$prefix."_session AS w LEFT JOIN ".$prefix."_users AS u ON u.username = w.uname WHERE guest = '0' ORDER by u.username ASC


my query is:-

$isnr = $db->sql_numrows($db->sql_query("SELECT * FROM ".$user_prefix."_premium_members_zone WHERE user_id='$session[user_id]'"));

Give this a shot...


SELECT w.uname, u.user_id, u.user_level, u.user_rank, u.user_allow_viewonline, p.user_id AS premium FROM ".$prefix."_session AS w LEFT JOIN ".$prefix."_users AS u ON (u.username = w.uname) LEFT JOIN ".$user_prefix."_premium_members_zone AS p ON (p.user_id = u.user_id) WHERE w.guest = '0' ORDER by u.username ASC


If they are premium then 'premium' will have the user_id variable.


if ($session['premium']) {
     //do something
}
