We’re done with our plugin, but we do have an opportunity for optimization as well as housekeeping. It’s a good practice to walk through your code when you’re done to: re-evaluate look for optimization opportunities do some housekeeping like commenting, formatting, and cleanup and ensuring everything in a file supports the intent of that file. Let’s walk through our Metadata Module together.
WooHoo! You did it! I’m so proud of you. Whew that was a long, long lab. But it was more than just building a reusable meta box module. My intent was to help you learn about: the Reusable Mindset – developing how you think about software, quality, and costs Architecture – developing how you layout your code Advanced programming concepts for filtering, merging, recursively merging and replacing, and remapping of arrays, as well as assigning a callable to a variable and then invoking it. Tell me what you think Now I want to hear from you. What do you think? […]
We’re nearly done with our save functionality. Let’s walk through it and talk about how it works. We’ll also manually test each piece of it to ensure it’s performing as expected (i.e. expected behavior). We’ll fix a problem too. We’ll also talk about and explore how to assign a callable to a variable and then invoke it like this: Here’s the link to Callable in Docx for you.
In the last episode, we saw the ‘meta_key’ configuration in our custom fields. That is coming from our default configuration model. Since there’s nothing to overwrite it during the recursive merge in the configuration store, it is added into our configuration. How can we remove it? Let’s talk about that in this episode. We’ll talk about protecting your module’s code when selecting the strategy to implement.
To make our save functionality reusable, we need to remap our custom fields’ configurations to rearrange and group them into defaults, delete state, and sanitizer function. Although you could do it in the configuration model itself, that requires you to be redundant, repeating the meta key over and over. Don’t do that. Instead, let’s build a function that programmatically remaps (rearranges) what we need for our save by grouping the keys together.
We abstracted the code that checks all of the various states to determine if it’s okay to save the custom fields into the database, i.e. continue processing the meta box. In this episode, you’ll add new checks for autosave, ajax, and cron (future posting).
We have a problem with our architecture. Do you know what it is? We have no way to differentiate and fetch only the keys for a specific component or module. In your work, you’ll likely have multiple modules using the ConfigStore. For example, you may have shortcodes, widgets, meta boxes, and custom post types all loading configurations into the store. How can you get only the configurations for the meta boxes? Right now, you can’t. In this episode, we’ll walk through a refactoring process to provide the means of fetching keys for just that component or module level. You’ll add […]
We have a structural error in our configuration models. Oh bummer. Did you notice it? In this episode, let’s fix all 3 files before we move onto the Configuration Store.
We’ve completed our meta box configuration model. Now, let’s take that model and load up our 2 custom implementations. You’ll want to store each configuration file into the config folder. If the plugin was doing more than a meta box, then you’d put the configs into config/meta-box folder. Resources intval sanitize_text_field
In the last episode, I challenged you to complete the render parameters yourself. In this episode, we’ll walk through how I solved it. We’ll fill out the custom fields in our Configuration Model. Plus, we’ll refactor our render function for our new generic, configuration business logic.
