I see your question has already been answered, but I'll add a tip that works
well for me. Whenever I want to perform an SQL query that involves PHP
variables I will write the query string to its own variable instead of
directly into the function. Then use that variable in the query
function...
$query = "SELECT * FROM my_table WHERE column1 = '$mydata' && column2 =
'$mydata2' ORDER BY $order_col $asc_desc";
$result = mysql_query("$query", $db);
