How to Populate Two Columns in a Table with Different Iterations in PHP/Laravel

When working with databases and displaying data in web applications, it’s common to encounter challenges related to how data is presented. In this guide, we aim to address a specific query from a developer who wants to display two arrays of teams (rosterWhite and rosterBlack) in a table format. Instead of showing all names in a single cell, the goal is to display each name in its own row under the respective columns: "White" and "Black".

The Problem

The developer provided the following current implementation. The teams are queried in the controller using Laravel's Eloquent:

In the view, they are currently trying to iterate through both arrays but are facing the issue of populating them in a single table cell. The result looks like this:

However, the desired format is to have the names appear vertically, each in its own row:

The Solution

To achieve this table layout, we can make a few modifications in both the controller and the view.

Step 1: Modify Your Controller

First, in the controller, ensure you retrieve the two rosters as before, but now also determine the maximum count of players in either team:

Step 2: Update Your View

Now, in the view, we’ll use a for loop to create rows based on maxCount. This allows us to display each player’s nickname vertically, with a conditional check for each team:

Tips for Optimization

Using Null Coalescing Operator: You might want to simplify the existence checks. Instead of using @if, you can use the null coalescing operator (??) which provides a default value if the index does not exist:

Conclusion

By following these steps, you can efficiently populate your table with two different arrays, ensuring that each name appears in its own row under the correct column. This approach not only organizes your display better but also enhances readability for your users. Don't hesitate to explore more about Laravel and its capabilities to improve your web applications.
