Hi everyone,
I'm a bit confused as to why $id is used as an argument within the get_item_html() function in this part. It's not being used in the body of the function and so I don't really understand the use of it.
I've removed it from my code and therefore also removed what we pass as parameter for the $id argument, and my example site works just like the teacher's.
Is there a specific reason to use the $id as an argument here? Am I missing something? Would appreciate any help in understanding this.
Thanks in advance!

12,836 PointsIt appears that we indeed use the $id in a later video :)

12,836 PointsThanks a lot for responding Jack. I'll disregard it for now as well unless I see it pop up again in a future vid.
Cheers!
