my questions is actually pretty basic since I am a PHP newbie. I am referring to this line of code:
unset( $column_headers['coupon_items'] );
Behind ‘coupon_items’ I would like to add more parameters, so I tried this:
unset( $column_headers['coupon_items', 'date', 'something'] );
Unfortunately, this leads to a php error. How can I place parameter behind each other in this case.
Any ideas are appreciated, thanks!
