Introduction

When working with jQuery DataTables in combination with Laravel, you might encounter the task of adding extra columns to your data table. One common scenario is when you need to display actionable elements, like edit or view buttons, alongside your data entries. In this guide, we will explore a solution to add two additional columns into your DataTable while keeping things straightforward and organized.

The Problem

A developer faced an issue while trying to add two action columns to a DataTable displaying user information from a database. They were experiencing problems with rendering the second column correctly. The initial approach led to unexpected results. Here’s a brief look at the troublesome code:

Upon triggering the AJAX call, the returned data structure showed that the second column ('action2') was malformed, leading to confusion and frustration.

The Solution

After some introspection, the developer discovered that the solution was much simpler than originally anticipated. Here, we will break down the steps that led to the successful rendering of the two additional columns.

Step 1: Simplifying Data Return

The developer realized there was an opportunity to simplify the data retrieval and rendering process. Instead of adding each column with complex functions directly within the DataTable, it was best to render the action buttons straight within the JavaScript after the data was successfully fetched.

With this modification, only basic user information is returned, and action buttons will be handled on the front end.

Step 2: Define URLs for Action Buttons

Next, you need to set up the URLs that your buttons will link to. This is easily done by defining them using Laravel’s URL helper:

Step 3: Customize the Frontend DataTables Initialization

In your JavaScript code, you will now define the two Action columns in the DataTable configuration. Here’s how to do it with the colDefs for your DataTable:

Overview of the Render Function

Data Retrieval: The data parameter represents the unique identifier for each record.

Link Creation: A link is created that incorporates the edit and show URLs, appended with the unique ID for that row.

Conclusion

Adding two columns to your jQuery DataTables doesn't have to be a complex process. As illustrated, the key is to rethink the structure of your AJAX data return and effectively utilize JavaScript for rendering additional action buttons. By following these steps, you can enhance your data display swiftly and maintain the organization of your codebase.

Now you can create a more dynamic and interactive data representation with jQuery DataTables while providing user-centric actions such as edit and view directly accessible from the table rows.
