WORDPRESS ADMIN CODE

That said, feel free to do that in your code though if you prefer! Creating our admin page classĪlright, so we have a pretty good idea of what makes up an admin page now! The next step is to create a class that can handle these different elements of an admin page. But we’re not going to design a class to do generate HTML like we did in it. This article is just going to reuse some of the ideas seen in that article. (That’s some pretty horrible self-promotion right?) It’s just there for reference. Now, there’s no need to read this article.

WORDPRESS ADMIN HOW TO

Lucky for us, we’ve covered how to generate HTML with object-oriented programming before. (And that’s one of the reasons why it’s so unpopular.) It’s that it doesn’t help generate the HTML of the admin page. There’s one big problem with the settings API. That’s why we’ll use the settings API to do this. (That’s why everyone has a different way of doing it!) That said, we want to use as many WordPress systems as we can for this. There are advantages and disadvantages to each of these methods.

And some do something even more extreme and build a single-page application for their admin page! While others choose to render it all themselves using PHP. But it’s true that WordPress developers use a lot of different methods for rending the HTML of an admin page. This means that there are almost as many ways to do this as there are WordPress developers! Ok, this might be a slight exaggeration. There’s no consensus among WordPress developers on the best way to do this. It’s how to render the HTML of the admin page. The function parameter is a good way to bring up the most problematic element of an admin page. (And who doesn’t want that!?) Rendering the admin page The parameter is optional, but, in practice, you need to use it if you want to display your admin page. It’s a callable that WordPress will use to display the content of the admin page. You need this slug to be unique otherwise you’ll run into weird display bugs. This is the slug that the admin page will use. The last mandatory parameter is menu_slug. For example, a plugin that deals with comments might want to use the moderate_comments. Outside that common scenario, it varies on the context of the admin page. In general, a lot of plugins use the manage_options capability to only display an admin page to administrators. This can be a bit overwhelming when you’re trying to find the right one to use. That said, there are a lot of possible capabilities to choose from. That’s the WordPress capability that the user must have to see the menu in the WordPress admin. Next, you have to give the function a capability. The other is the title of the admin page will have in the parent menu that we defined in the first parameter. The first is the title tag when you go to the admin page.

You then need to give the function a page_title and a menu_title. That’s the slug of the parent menu that the admin page will show up on.

If you’re not using a shortcut function like the add_options_page function, you first need to give it a parent_slug. The add_submenu_page function itself has a lot of parameters and it requires that you use all but one of them. That said, behind the scenes, all these functions call the add_submenu_page function.

There are also shortcut functions such as add_options_page that let you add a submenu page to a specific WordPress menu. With WordPress, you register an admin page using the add_submenu_page function. We’re going to start with registering an admin page. These are registering the admin page and rendering it. All of them fall into two broad categories. With this in mind, let’s go ahead and look at the different elements of an admin page. We’ll do that by analyzing what makes up an admin page in the first place. The key to achieving this is to understand the role of these different moving pieces in the larger picture of an admin page. There are a lot of different moving pieces that you have to take in consideration in your design.Ī well-designed admin page class will combine these different moving pieces into a cohesive class. (Or they might even need more than one!) That said, designing an admin page using object-oriented programming isn’t that straightforward. While others might need to create custom post types.īut one component that almost every plugin needs is an admin page. For example, some might need to use shortcodes to achieve their purpose. A WordPress plugin can have a lot of different components.
