Displaying Selected Categories Post Titles and Thumbnails in Elementor Using SELECT2 Control

When developing custom features in WordPress using Elementor, one common requirement is to display a curated list of posts from specific categories. If you've recently created an Elementor SELECT2 control that allows users to select categories, you might be wondering how to fetch and display the titles and thumbnails of the posts from those selected categories. In this guide, we'll walk through the process of achieving exactly that. Let's dive in!

Understanding the Problem

You have set up a custom post type named 'video' and associated it with a taxonomy called 'video_categories'. Users can select multiple categories via the SELECT2 control you've created. The core goal now is to display the titles and thumbnails of the posts belonging to the selected categories in the Elementor interface.

Step-by-Step Solution

Step 1: Modify the Control

To start displaying the selected categories, you need to change the key used in your render() function. Originally, the selected categories were being fetched using $settings['show_elements']. However, we need to access the selected video categories instead.

Step 2: Getting the Category Names

The direct output from $settings['video_categories'] will only retrieve the IDs of selected categories. To display the actual names, you can use the get_cat_name() function. Here's how you can implement it in your render function:

Step 3: Fetching Posts from Selected Categories

To retrieve the posts associated with the selected categories, you will need to use a custom query. Here's how you can implement a basic WordPress loop that fetches and displays post titles and thumbnails from the chosen categories:

Step 4: Implementing in Content Template

To reflect these changes in the Elementor's live editor, you need to adjust the _content_template function accordingly. For now, assume that we will show the category names you fetched earlier in a similar manner as the render method.

Overall, your _content_template() should hold functionality similar to the following:

Conclusion

By following the steps outlined above, you can successfully display the titles and thumbnails of posts from selected categories in Elementor using the SELECT2 control. This not only enhances the user interface but also provides users with quick access to relevant content based on their selections. Now that you have a clearer idea of how to implement this feature, you can take your Elementor customization to the next level!

Now go ahead and try this out on your WordPress site. Happy coding!
