What is the best way to clear a value in a table? Scenario: If user choose to delete article image, the filename in the table should be cleared. I have used $old_image = ""; to clear the name and then update table, but that doesn't seem to clear the value completely, as when I do a check afterwards if filename was deleted by using statement if($filename), it always return True, as in, there is a value present for $filename even when name has been cleared. Have a got this correct or is there something else I am missing, In advance, thanks!
