hi,
I am having trouble with some data i am retrieving from a mysql
database.
after a query i am using mysql_fetch_array in a while loop to retrieve
data. ie;-
$row = mysql_fetch_array($result);
once i have a $row i am getting relevant data i want using;-
$data = $myrow["field_name"];
where "field_name" actually exists but may not be used (null).
the problem is that if it is not used then warnings are generated,
even if i do;-
if($myrow["field_name"] != null){
$data = $myrow["field_name"];
}
it still generates warnings. can any one help?
thanks in advance
scott
