Warning: Supplied argument is not a vali

[Anon]

I seem to be getting the following error;

Warning: Supplied argument is not a valid MySQL result.

On this line of code;

$attend = mysql_fetch_array($attended);

The data is in the database but is not recognised.

I have used a debugger on but does not seem to work.

$attend = mysql_fetch_array($attended);

debugger_on ("cis-m1-4.sund.ac.uk")
or die ('The debugger could not be enabled');

I have been told to debug my code but I do not know how to do this? Is there anybody out there who can help.

That error message means that you are not giving the function a valid mysql resoure as the argument. This could mean a few things:
1. Your mysql_connect line is failing.
2. You're losing your mysql session somewhere
3. Your query did not return any results
4. You mis-typed the variable you are passing.

There are probably more I'm forgetting but amybe that will help...

Try the following:

$attend = mysql_fetch_array($attended);
echo mysql_errno().": ".mysql_error()."<BR>";

hope that helps
