TinyMCE and WordPress: Adding User Input

August 6, 2015 / Tom / 0 Comments

In the previous post in this series, I showed how to add content to the post editor using a custom TinyMCE button. The problem with the approach, as we’ve covered thus far, is that the content that we’re adding to the editor is hard-coded.

We’re rarely going to want to be doing this, right? I mean, wouldn’t we rather grab input from the user and then add that to the editor?

My very own copy TinyMCE Editor. Show spectacular.

For some, this may be creating a shortcode based on some input, for others it may be grabbing input, making an Ajax call, and then putting the result of the request into the editor, or it may be something as simple as taking whatever input the user has provided in a prompt and then adding it to the editor.

Though the latter case is not likely something that is a realistic use case (after all, if they just wanted to put something into the editor, why not just, you know, enter it into the editor?), it’s something that will make rounding out this series a bit more complete because it will show how to connect displaying a prompt to the user, grabbing the input, then using the TinyMCE API to drop the input into the editor.

So that’s what we’ll do.

Get The Post Type of the Current Post with JavaScript

August 5, 2015 / Tom / 0 Comments

Whenever you need to get the post type for a given post, there are a couple of ways to do this:

If you’re in the dashboard, then you can use `get_current_screen()` and then access the `id` property of the object that’s returned. You can read more about this in the Codex.
If you’re on the front-end (or even in the dashboard, really), you can use `get_post_type`. This is also covered in the Codex.

But what if you want to grab the post type of the post that’s currently being edited on the client-side (read: via JavaScript)?

How To Save WordPress Submenu Page Options

August 4, 2015 / Tom / 0 Comments

If you’re using functions such as add_menu_page or add_submenu_page to create pages in the WordPress dashboard, it’s pretty easy to get something up and going, but what if you’re looking to actually save WordPress submenu page options?

Submenu Page Options

That is, let’s say you’re creating a page in the dashboard that’s tied to a new menu item – perhaps something that’s being added to the Tools menu – and you want to display some options among some other text or some other element or set of elements that you’re displaying.

It’s completely possible to use the Settings API to do exactly that, but it may also be a little heavy-handed for saving a couple a small set of options.

Luckily, WordPress has a hook that’s available that makes it pretty easy to save information like this that’s completely usable outside of the Settings API.

How To Remove WordPress Meta Boxes

August 3, 2015 / Tom / 0 Comments

Out-of-the-box, the meta boxes that WordPress displays on the dashboard aren’t exactly overkill. I mean, if you’re a blogger, then I think the chances are strong that you’ll need:

Publish
Categories
Tags
Comments
And maybe the Excerpt feature (depending on your theme)

But if you’re building a solution for someone else where that information is irrelevant, wouldn’t it be worth removing the WordPress meta boxes to make the dashboard a little bit cleaner with less irrelevant options?

jQuery is Undefined

July 31, 2015 / Tom

For those who have been in web development for sometime – especially those who have seen the rise (and stuck with) jQuery – then you’re likely all too familiar with some of the potential errors messages that you may see when working with the library.

But if you’re someone who is just starting out and perhaps you’re learning JavaScript and/or jQuery and you’re getting familiar with the developer tools that ship with your browser of choice, you’ve got your plate full of things that you’re having to debug.

jQuery

And sure, Google is your friend and being able to ask questions on sites such as Stack Overflow and other similar sites is nice (though the community may not always be such), but it’s not always fruitful.

In those cases, I think those of us who have gone down the same road that you’re traveling have some obligation to help educate what the problem is, why it’s happening, and how to resolve it.

And that’s what I’ve tried to to do in my most recent article for Envato.
