Hey, Zac: Thank you very much for teaching us all the wordpress knowledge. It would be a lot harder to learn wordpress without your videos. I am learning woocommerce recently, and find it is very different to other open source platforms. We use add_action and remove_action to modify small layout changes. And we use add_filter to modify the functions. I just couldn't get my head around this add_filter. I am not sure if it is just me. If possible, can we have a class for this add_filter?
Many thanks

Courses Plus Student 46,022 PointsFilters still elude me to some extent. I have actions down, but filters are a little harder to grasp. I found a great article on them, though. Maybe that will help you some.

Treehouse Guest TeacherHey Luke!
Have you watched the plugin course yet? We get into a good bit of detail on this.
Also, in the Ecommerce course up on the roadmap we have a whole stage dedicated to all the actions and filters built into WooCommerce so you should walk away from that with a real solid understanding :)

7,577 PointsHi Zac:
I have gone through these tutorial.
Still a bit confusing. For example.
function custom_excerpt_more ($more){
return '';
}
add_filter('');
What is $more? I understand it is an object, but where do I get the object name? Sometimes, I see 2 objects in the brakets, what are they?
