@jonathanbossenger I would like to work on creating lessons for Module 3: An introduction to developing WordPress themes

[jonathanbossenger]

Thanks @cynthianorman, I have assigned you to this ticket. Feel free to unassign yourself once you have completed those lessons.

[jonathanbossenger]

As of 2023-12-11 I have removed the module on the Common APIs, for two reasons:

a) this list only includes PHP based APIS
b) I'm still not convinced this needs an entire module, and perhaps it would make more sense just to link to relevant APIS when they are used inside lessons.

I am adding the list here for reference.

Module xx: An introduction to Common WordPress APIs

Objective: Introduce the most common WordPress APIs, and how to use them.

Lessons

• Responsive Images

• Transients

Hi @cynthianorman

When you have a moment, I wanted to touch base with you regarding Module 4: An introduction to developing WordPress themes.

I want to make sure that contributors can set their own deadlines, but also be mindful of the fact that we're aiming to launch the new Learn redesign with learning pathways by July 2024.

So I wanted to get an idea from you when you feel like you'll be able to complete the first iteration of that module.

Thanks

[cynthianorman]

Hi @jonathanbossenger . I feel confident that this will change into Feb. I would expect to have the Beginner Developer Module 4 lessons done by end of Feb.

[jonathanbossenger]

Thanks @cynthianorman

Today I was reviewing the learning pathway outline, and I discovered that the lesson on the Create Block Theme plugin was added to the Block Development module, and not the Theme Development module. The objective of this lesson would just be to introduce the learning to the plugin, and it's basic functionality.

I've moved it to the right place, but I wanted to check if you would prefer me to handle this lesson, or if would you be able to squeeze it into your February plans.

I completely understand if you don't have time to add another lesson, and I am happy to create this specific one.

[cynthianorman]

Hi @jonathanbossenger

Thank you for the offer but I'm more than happy to add that lesson. I think cohesiveness within a given module was a great idea you had during our previous talks.

[jonathanbossenger]

Ok, thanks @cynthianorman.

[jonathanbossenger]

Note to contributors, while working on the plugin module today, I realized that we need to cover the concept of hooks earlier on because most plugin and theme development requires an understanding of hooks.

I have therefore moved the hooks module to module 3, and tomorrow I will work on the introductory lesson of that module, as well as reworking the original tutorials on action and filter hooks for the learning pathways.

You can find the original tutorials linked in action and filter hook issues, if you want to get an idea of what will be covered.

[jonathanbossenger]

Noting that #2088 and #2089 have been moved to #2045.

[jonathanbossenger]

Update, moved the Roles and Capabilities module to the Plugin developer pathway.

Added the lesson on enqueuing CSS and JS to the Introduction to plugin development module.

[jonathanbossenger]

@cynthianorman all your introduction to developing WordPress themes videos have been published on YouTube. I've left a comment on each issue, asking for the YouTube chapter markers, so I can add them. (Let me know if you have any questions about that).

You should also have the required access to add the lessons to learn.wordpress.org, so feel free to go ahead and update/publish those lessons, and close the issue once the lesson is published.

[cynthianorman]

@jonathanbossenger sounds good - thank you!

[jonathanbossenger]

@cynthianorman I just wanted to check in to see how it's going with getting the lessons for the An introduction to developing WordPress themes module published on Learn.WordPress.org?

[cynthianorman]

@jonathanbossenger that shouldn't be a problem for me to fit into this month.

[jonathanbossenger]

@cynthianorman I've closed all the issues in module 4 An introduction to developing WordPress themes that are published on Learn.WordPress.org. Once you publish the final two, please go ahead and close those issues as well. Thanks
