Labs

Labs are hands-on coding projects that you build along with Tonya as she explains the code, concepts, and thought processes behind it. You can use the labs to further your code knowledge or to use right in your projects. Each lab ties into the Docx to ensure you have the information you need.

Each lab is designed to further your understanding and mastery of code. You learn more about how to think about its construction, quality, maintainability, programmatic and logical thought, and problem-solving. While you may be building a specific thing, Tonya presents the why of it to make it adaptable far beyond that specific implementation, thereby giving you the means to make it your own, in any context.

After Entry Widget Area

Let’s go through the function genesis_after_entry_widget_area() in Genesis, as it is responsible for building and then rendering out the widgetized area for the “after entry widget area.” You’ll explore how the ! operator in PHP works as well as looking at the conditions which say, Yes let’s go ahead and render it out. For the customization part of this episode, you will walk through different techniques to turn off (remove) this component. Let’s say you don’t want the after entry widget area in your theme. Ok, this episode discusses how to properly disable and remove this component.

Reorder Author Box & After Entry Widget Area

Let’s do some customization by reordering the author box and after entry widgetized areas. I’ll show you two different ways to move these components such that the author box is after the widgetized area. You’ll also learn about why you need to unregister the Genesis callback by using remove_action, as you see the callbacks in the WordPress Core Plugin API’s event registry table, which is stored in the global variable $wp_filter. To learn more about the WordPress Event-Driven System and the Plugin API, see the following labs and Docx: WordPress Plugin API – Introduction & Registering Events add_action remove_action do_action

Out-of-the-box, the framework adds the following components: Author Box After Entry Widgetized Area Previous and Next Navigation (adjacent entry nav) Comments You can see the execution order within the Genesis loop here: In this episode, you’ll walk through the codebase to get an overview of the above components.

Entry Footer – Post Meta

At the bottom of each article, you are used to seeing the post meta. This is where Genesis, by default, renders out the post’s category(ies) and tag(s). This functionality occurs in the function genesis_post_meta in the file “genesis/lib/structure/post.php”. Part of this function, just like with the post info, the shortcodes are being filtered by an event, which is named genesis_post_meta, and then processed through the WordPress Core function do_shortcode(). This is the filtering event which fires to call any functions that are pre-registered to the event name genesis_post_meta: $filtered = apply_filters( ‘genesis_post_meta’, ‘ ‘ ); Within Genesis, it has registered […]

Entry Footer – Overview

After the entry content and still within the <article>, Genesis provides the ability to display additional content. This is the entry footer section. By default, Genesis will render out the post categories and post tags and the post meta. In this episode, you see each of the callbacks which are registered to build the entry footer HTML markup. The event name for this section is genesis_entry_footer.

After Entry Content

Genesis provides you with an event where you can add content between the entry-content and entry-footer HTML markup areas. To use this event, you will register your function (callback) to the event name genesis_after_entry_content. In this episode, you’ll see where to use it and where the content would occur with the HTML markup on the web page in the browser.

Entry Content – Post Permalink

What happens on an archive page when a post does not have a title? Did you know that the Genesis framework has a default registered function called genesis_do_post_permalink, which is found in genesis/lib/structure/post.php? What will happen is: Genesis adds the permalink and some HTML markup after the content and post navigation. In this episode, you’ll walk through the function to understand how it works. For the customization exercise, you’ll again use the PHP construct called str_replace() to add some prefix label to the link.

Entry Content – Post Content Navigation

In this episode, you’ll take a look at the Genesis framework function genesis_do_post_content_nav, which is found in genesis/lib/structure/post.php. This function is setting up the arguments which are passed into the WordPress Core function wp_link_pages. The intent of this function is handle in post navigation, i.e. paginated posts. Did you know that functionality even exists? I’m also introducing you to a PHP construct called str_replace() which allows you to swap out parts of a string by searching for a given pattern. As part of your customization hands-on work in this lab, you’ll be replacing the “Pages:” string, which is hardcoded in […]

Entry Content – Post Content

As part of the entry content, Genesis has a default registered callback for building the content based upon various settings (who you have it configured) and which web page is being displayed. The function is genesis_do_post_content, which is found in genesis/lib/structure/post.php. Looking at the function, you’ll see that there are four (4) different conditionals to determine what content is displayed: the web page is a single piece of content, i.e. is_singular() is true “excerpts” are set for the archive (because it’s configured that way in Genesis > Theme Settings) the archive content is being limited (because it’s configured that way […]

Real Refactoring Example

Even though I use and like Genesis doesn’t mean there aren’t areas where it doesn’t fully comply with clean, quality coding techniques. In the last episode, I showed you the code for processing the post image. Did you notice that the code within the function genesis_do_post_image() will not run (none of it) if the conditional expression is not true? Ah, this is a perfect example of when to return early. Return early pattern: when you are done processing and nothing else in the function/method is going to be processed, then so bail out and return early. Why? Why would you […]
