JetEngine: How to Create a Custom Meta Box. Meta Field Types Overview

This tutorial reveals the process of working with custom fields made with JetEngine plugin, one of the plugins from a huge Jet family.

We’ll explore how to create a custom meta field with JetEngine plugin and take a closer look at types of these fields.

Custom meta fields display additional information about your custom or default post. You can select the preferable type and add content to it. Let’s dive deeper into the topic.

Adding Meta Fields to the Post

1 Step — Add Meta Box

Once you’ve created a custom post type with JetEngine, you can also create some additional custom meta fields for it. Go to the JetEngine > Meta Boxes block in the WP Dashboard, click the “Add New” button to add a new meta box to the post type you’ve created previously.

You will see a settings window, where you should specify the meta box title, select the Post option in the Meta Box for the field.

There are also available Taxonomy and User options in the Meta Box for the field.

  • If you choose the Taxonomy, you are able to select the taxonomies where this meta box should be shown.
  • In case you want to restrict access for different users, select the Meta Box for: User and set the visibility of meta fields. If you select the “Edit User” option from the dropdown, that meta box will be visible only for website administrator on the Edit User page. And if you pick the “Edit User & Profile” option – the meta box is visible at the User Profile page and the user will be able to edit it.

When you choose the “Post” type, you can define for what post types it will be enabled in the Enable For Post Types bar. Besides that, you can choose what Specific Posts this meta box will be shown on, and the Excluded Posts where it won’t be visible.

If you turn the `Edit meta box` link toggle on, it will add a cog-shaped editing button to the post customization page in the dashboard. Clicking on that button will open the meta box editing page.

2 Step — Add Meta fields

Now let’s proceed to add and customize meta fields included in this meta box. For that, you should open the Meta fields tab and click the “New Meta Field” button. You need to fill in three fields:

  • Label – type in the title of the field here. This is how it will be shown to you and other users furtherly. 
  • Name/ID – this value is generated automatically, according to the text you put into the Label bar. If you want to change it, keep in mind that the ID shouldn’t include spaces and make sure it consists only of the letters and numbers. The auto-fill will also add a random number to the name if it is not unique. The fields with similar IDs could confuse you and cause some trouble if you’d like to use them somewhere else. That’s why the auto-fill prevents the usage of similar IDs. By the way, if you’ll choose to fill the Label bar with Cyrillic letters – the auto-fill will transliterate it to English.
  • Object type: Field – here you can choose the type of the object. The Field option means that you will be able to add values there. Tab, Accordion, and Endpoint will create a specific layout.
