@laura, that sounds frustrating. I just sort of picked this stuff up, and I think I’ve wrapped my head around “hooks”.

From what I understand, a “hook” is a way of attaching a code function into a given framework (in this case, the WooCommerce framework), without needing to edit their code base.

It’s like saying, “Hey WooCommerce, I want you to do this extra thing for me, but I don’t want you to change anything about yourself.”

In general, this is a good practice because as WooCommerce grows and updates, they won’t overwrite your changes, and if something breaks, it’s a bit easier to debug.

Before you get into writing any code, read the template structure article that IgniteWoo posted above. As I was trying to figure out how to make WooCommerce do what I wanted it to, I used these documents:
Learn how to add custom form fields to checkout – https://docs.woothemes.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/

Reference of all the hooks and filters you can glom onto –
https://docs.woothemes.com/document/hooks/

I know this is a lot of information to throw at you, but hopefully this can get you going in the right direction.

Since updating, I’m running into an issue where new pages are being redirected to a /wpgforms/ page.

Full disclosure, I’m using a heavily customized theme that I didn’t build that’s being used for my work. As a result, it’s difficult for me to provide a lot of information, since I can’t say with 100% certainty how this plugin is interacting with the theme.

In any case, it was working, but stopped working after I upgraded the plugin.

Let me know if you have any ideas, and I’d be happy to try and get more info for you.

Alright, in speaking with our sys admin, there wasn’t a whole lot more information, but here goes.

So as I said our website is using a varnish cache, which was causing the POST to be cached. Our sys admin added POST methods as an exception to varnish. This way every time a post is sent, it goes directly to our web server as opposed to the cache.

Hope this helps.

Hi all,

We were experiencing a similar problem. We were using a varnish cache, and discovered that the POST was being sent to the cache as opposed to where it was supposed to go.

Our sys admin altered a setting (probably a redirect, but I don’t really know because my knowledge in this aspect is woefully limited), that made posts post to where they are supposed to.

I hope this isn’t too vague, but if so I can probably get a better description from our sys admin if the need arises.

Good luck!

UPDATE: My mistake, this is all user types, not just subscribers.

Huh. Cool.

I’ll give it a shot and see how it turns out.

Thank you again!

Hi David,

Thank you so much for looking over my stuff. I’ve checked all of my category slugs, and everything appears to have been matched up (the teacher/teachers discrepancy was only in my first post). Even so, I’m still terrified that I’ve done something really dumb, like having a typo.

In any case I looked at the debug, but my ability to understand it is limited. Right off the bat I see that the beginning statement for the “not working” gallery is “mla_debug empty gallery”, while the working one does not include it (which makes sense).

In any case, here’s the debug for the working gallery call:
[mla_gallery post_parent="all" post_mime_type=application/pdf attachment_category=teachers,getting-started tax_operator=AND link=file orderby=title order=desc mla_debug=true]

There aren’t a whole lot of people I can turn to for guidance, so I appreciate your time quite thoroughly.

Thanks again.
