Hello, $this only calls variables inside of a method. In your function, you are calling a variable that was defined inside of your function called $columnName. You should past the whole class. Not just the methods. "The pseudo-variable $this is available when a method is called from within an object context. $this is a reference to the calling object (usually the object to which the method belongs, but possibly another object, if the method is called statically from the context of a secondary object). " taken from http://www.php.net/manual/en/language.oop5.basic.php The parent keyword indicates that this is an extended class. You are referring back to the master class. Ravi.
