Dynamic Field Widget Overview
In this tutorial, you’ll have a glance at the functionality of the Dynamic Field widget from the JetEngine WordPress plugin.
The Dynamic Field widget of the JetEngine plugin helps you to display the content from meta fields. This widget pulls the data from the specified source and displays it using the set style and content settings. Here are the types of meta fields that the Dynamic Field widget can display:
And now let’s go through the widget’s features.
Dynamic Field Content Section Settings
Drag and drop the Dynamic Field widget on the page and let’s look through the content settings.
- Source. In the dropdown, you can see a list of available sources from where the data will be pulled out. If you choose Post/Term/User/Object Data, the content will be pulled from the default meta fields of the post, term, user, or object. The field can be specified in the Object Field select. The Meta Data option will take the content from one of the meta fields created by you using the JetEngine plugin’s functionality. You can select a concrete field in the Meta Field drop-down menu or define it by typing in the Custom meta field/repeater key. The Options variant allows you to choose meta fields created for the Options Page. And if you choose the Relation Hierarchy option, the data will be taken from the fields of the posts related to the current one. You can choose what type of post to Get and select the type from the From Post Type drop-down list. The Relation Meta Data option takes the data from the meta fields created for relations. We also have a dedicated tutorial about the relations dynamic output;
- Field Icon. If you want to add an icon to the field, here you can choose it from the library or download it as an SVG file;
- HTML Tag. This drop-down menu allows you to choose the HTML tags in which the field will be wrapped. DIV is a tag that is used to define containers, H1-H6 turns the field into a headline, P defines the field as a paragraph, and SPAN marks it as an inline part of the document;
- Hide if value is empty. Turn this option on if you want to hide the field if it’s not filled;
- Fallback. If you don’t want to hide the field if it’s empty, in this text area, you can define what text to show to the user instead;
- Filter field output. This one needs extra attention, so we’ll describe it lower;
- Customize field output. Turn this toggle on to add the text before and after the value pulled from the meta field; %s stands for the value that is pulled; just add some content before and after it to add some text before and after the value;
- Context. This field helps specify the field’s source and collaborates with the Source option. According to your settings, there can be such options:
- Default Object. Shows data for the current page or listing template;
- Current User (global). Shows data according to the user for whom the page was created;
- Current User (for current scope). Shows data according to the user, which is currently proceeding. For example, there is a listing of users that shows the posts written by the user after clicking on them. In this case, if you choose the Current User (for current scope) context, it will display the meta field value of the user you have just clicked on, not the logged-in user;
- Queried User. Shows data for the currently logged-in user or the user mentioned in the URL (the user ID is in the URL);
- Current Post Author. It will show the meta field value of the user that is the author of the currently opened post;
- Default WordPress Object (for current page). It always shows the data of a current global object for the current page defined by WordPress. For instance, on a single page/single post, it will always be the current post, even if you go to the listing added to this page;
- Current CCT item author. Shows the data in the meta field of the user that is the author of the currently opened CCT item. It can be used in the Listing Template for CCT to show the information about the CCT item author. To learn more about CCT, proceed to the How to Create a Custom Content Type tutorial;
- Related Items From… Shows the data for the created relation. To learn more, navigate to the Relations Dynamic Output tutorial.
Filter Field Output Overview
This feature needs a detailed description. Enabling the Filter field output option allows you to display different data types. Dynamic Field widget can be used to show the data from, for example, Сheckbox meta field. To display it correctly, you need to use this filter.
Showcase Date, Time, and Datetime meta fields value as preferred
- Use the Format date callback to show the date pulled from the database using Date, Time, or Datetime meta fields. In the Format field, you can set the date’s format;
- Format date (localized) is the same as the previous one but shows the date that is already localized to the language of the website;
- Human readable time difference. This callback works with the Date and Datetime meta fields. It shows the difference between the date you put into the meta field and the current date. The difference is displayed in days. In the Additional meta key field, you can enter another meta field name, and this callback will show the difference between dates in these two meta fields. For instance, you can display the difference between the start and end date.

In the Divisor field, you can enter the number by which the field value will be divided; in the Multiplier, enter the number by which the field value will be multiplied, and the callback will show the final result. You can also identify in the Result precision field how many decimals can be shown in the result after the separator.
