How can I add a zip folder to an asset field in craft cms

Question

I'm quite new to the cms and would like to know how to programmatically add a zip folder to an asset field in craft cms using a plugin. So like listening to ENTRY_AFTER_EVENT and processing a zip folder and afterwards do something like $event->sender->assetField = zippedFolder

Any assistance is highly appreciated.

Thanks!

Thanks for assistance. I was able to solve the problem by creating an asset, got the asset id and added the asset field to the id: $event->sender->assetField = [newassetid];
