Re: [PHP] Banner rotation with links
On my home page i have all my banners in a MySQL database which includes the image path, the link, and the description as separate fields. The then do a MySQL query with a query that will look something like this: $query = select * FROM banner ORDER BY RAND() LIMIT 1; Seems to work just fine. -- Kevin Murphy Webmaster: Information and Marketing Services Western Nevada Community College www.wncc.edu 775-445-3326 On Feb 14, 2007, at 8:29 AM, Chris Carter wrote: How can I rotate a banner as well as the link in it within a page using PHP.

just wait till you have 10 items in that table :-)
in practice that may never happen and maybe MySQL can optimize a
SELECT that does ORDER BY RAND() LIMIT 1
(can anyone confirm what MySQL does with ORDER BY RAND() LIMIT 1 exactly in
terms
of scanning the table? - the MySQL docs don't mention whether this is scalable
at all)
*but* if that is not the case then using a field (call it 'randomized' or
something like that)
and indexing on that and then updating that field periodically with random
integers using a cronjob script would make the resulting query alot more robust
..
the compromise being that you don't get a different banner each request:
$query = select * FROM banner ORDER BY randomized LIMIT 1;
the compromise can be mitigated some what by doing something like this
(assuming you use sessions):
// BRC = Banner Random Count
if (!isset($_SESSION['BRC']))
$_SESSION['BRC'] = 0;
$query = select * FROM banner ORDER BY randomized LIMIT {$_SESSION['BRC']},1;
$_SESSION['BRC']++;

Hi depends on what moment you are changing the banner if you are doing it on a page change you can do this with PHP by querying a DB for a random banner (or non random thats up to you to decide) entry to display, each time you load the page. If you are wanting to do the banner change based on a time interval you would have to setup some javascript to do this for you, maybe generate it using php that formerly queried a database of banner entries. Google: banners +javascript first before posting, there's always an answer ;) Regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
