I do an insert using phpadmin, and i get back the error message (or maybe it's a warning?) The insert is of a duplicate on a unique field. I expected an error, but when I do mysql_error() or mysql_errno(), nothing comes back(and I do it the next line in the script). the 'mysql_query($sql, $link)' function DOES return false, but I'd like to inform the user what the error was. PHP Admin can get the 'error' why can't I?
