drayarms Posted May 31, 2011 Share Posted May 31, 2011 I have tried the following variations but non works if($row['relation'] = "" ){ if($row['relation'] = '' ){ if($row['relation'] = NULL ){ if($row['relation'] IS NULL ){ if(strlen($row['relation']) = 0 ){ So how would one refer to a cell that is empty?

Fadion Posted May 31, 2011 Share Posted May 31, 2011 You'll have to use the comparison operator: == //string datatype if ($row['relation'] == '') {} //numeric datatype if ($row['relation'] == 0) {} Quote Link to comment Share on other sites More sharing options...
