Re: [PHP] Not a valid MySQL resource?
I set it up so that I check the query for errors, and there are none. It is pretty random - sometimes the page works, and sometimes it doesn't, for no apparent reason. I haven't changed anything on the database side. Thanks.

Re: [PHP] Not a valid MySQL resource?
My page works fine from other computers - it just doesn't work from mine. I think it could be that the page is caching and IE6 isn't getting a new copy. How can I prevent it frlom caching? I've tried clearing my history, but I still get the error. Thanks.

Re: [PHP] Not a valid MySQL resource?
Always always always check your queries for errors before trying to use the result set. ie. $result = mysql_query($sql) or die(mysql_error()); (assuming you want a query failure to be a fatal error) -Rasmus On Sat, 30 Mar 2002, Brian Waskiewicz wrote: > Can anyone tell me what is causing the following error: > > Warning: Supplied argument is not a valid MySQL result resource in > /ip/sums/www/test/admin/mailing_list.phtml on line 123 > > The page will work fine one time, then I'll come back later and get the > error.

[PHP] Not a valid MySQL resource?
Can anyone tell me what is causing the following error: Warning: Supplied argument is not a valid MySQL result resource in /ip/sums/www/test/admin/mailing_list.phtml on line 123 The page will work fine one time, then I'll come back later and get the error. I won't change anything, but the page will work later on anyway. I know there's nothing wrong with the database server, and the query should return results.
