This may be a dumb question, but did you actually fetch the db query's results
and put them in $row before trying to use $row? In MySQL you could do
something like:
$query = "select * from my_table";
$result = mysql_query($query);
$row = mysql_fetch_array($result); //this statement would need to be inside of
a loop if there is more than one result
Thanks, Mari. That was it: I usually declare the variables first, then
on with the rest of the code. I had inserted the $row conditional values
right after the vars, before the rest of the query...just plain dumb.

flash remoting: you could use amf instead; its faster and easier to use.
on the php side just use http://amfphp.org/ or suchlike

Hi, thanks for reading, I hope you can help:
In my main file for an orders page I have the following code:
if (isset($_GET['filterby']))
{
$resultOrders = adminFilterQuery();
$numberOfOrders = mysql_num_rows($resultOrders);
}
else
{
$resultOrders = mysql_query("SELECT * FROM afy_order;") or
die(mysql_error("Could not query the database!"));
$numberOfOrders = mysql_num_rows($resultOrders);
}
adminFilterQuery() is a custom function that is supposed to return a
mysql_query, here are the last few lines of this function:
$query = "SELECT * FROM afy_order WHERE school_id = '{$school}' ORDER BY
{$order_by_param};";
$result = mysql_query($query);
return $result;
l am getting this error when I try to filter my query using a form in tandem
with the quey building function:
*Warning*: mysql_num_rows(): supplied argument is not a valid MySQL result
resource
where the line is the one where I use the mysql_num_rows function.
What am I missing here?
Thanks!

Likely your query failed due to an error.
Try adding an or die(mysql_error()) to the end of your mysql_query
statement to see what that error maybe

Hello,
I have a mySQL database server in Florida USA (EST) and I want to do a
query on a record in California, USA (PST) 3 hours earlier using PST
instead of EST.
I would like to add to my CORE page that offset of the timezone so I
can use it in a query like:
Select * FROM aTable WHERE ServerOffsetTimeStap >= Row_Start_TimeStamp
AND ServerOffsetTimeStap <= Row_End_TimeStamp
How would I do this?
Appreciate any help you can offer. Thanks!

There seems to be a misunderstanding. I am not eager to promote my code.
I just look forward to have my classes tested by as many people as
possible, so I get as many bug reports and feature improvements as possible.
The fact is that I developed this and many other packages for my own
purposes. Nowadays I could not live without them because they make me
several orders of magnitude more productive than if I had to do it edit
HTML code mannually as you said you did.
Anyway, maybe this surprises you, but I like criticism. Especially
constructive criticisms from people that are able to give specific
examples of what they do not like, instead of making vague claims as you
did.
I like constructive criticism because it helps me making my code better,
more useful to others and ultimately to myself. That is why I publish my
work as Open Source.
Unfortunately you did make any constructive criticism. There seems to be
no way to improve my work because you were not specific to what exactly
you find cumbersome, even less what you would different to make it less
cumbersome.
I never claimed it would be perfect for everybody. What is good and
productive for some, maybe hard and difficult for others, especially if
you try to learn all by yourself and never ask for help.
The class has a support forum where you can ask questions and always get
a response so you never get stuck.
http://www.phpclasses.org/discuss/package/1/
Anyway, I don't know if you ever asked for help because you are using an
anonymous identity here. Actually, I wonder why you bother to write a
special message anonymously just campaign against the forms class. It
makes me wonder if you have other reasons to do it that you may not be
revealing unrelated with the class.
Anyway, I am not upset. I am just sorry that you made many criticisms
without giving real examples to demonstrate your points. That way it
will not be helpful to anybody.
