is_null

[Joan Garnet]

It appears to be a normal function...

Why don't you post a little piece of code just in case...
bye!

Well, the variable is empyt, but it actually exists as soon as the column was created.
Better use this:

Code: Select all

if ($row_listContract['address_line_1'] = "") { 
  echo "It is null."; 
} else { 
  echo "It is not null." 
}

bye!
