How to Make orderBy Ignore Value 0 in Eloquent Laravel

Sorting data is a fundamental requirement in web development, especially when dealing with collections in frameworks like Laravel. However, you might encounter a situation where you need to sort your items based on a field that can have values of 0, null, or actual indices. If you do not want the 0 or null values to affect your sorting order, you may wonder: How can I make Eloquent's orderBy ignore these values?

In this guide, we will explore a straightforward solution to this problem using Eloquent’s querying capabilities.

The Problem with Sorting

When you try to sort a collection by a field that includes 0 or null, you might notice that these values are considered smaller than any non-zero indices. This can lead to unexpected ordering in your application's display.

For example, given the following collection structure:

Position: 0

Position: 1

Position: null

Position: 2

By default, sorting would result in:

Position: 0

Position: null

Position: 1

Position: 2

This is not an ideal sorting order for many use cases. Thus, the need arises to effectively ignore these values in your sorting logic.

The Solution: Using CASE in orderBy

Implementing a Workaround

One effective way to handle this is to use a CASE statement within the orderBy clause. A CASE statement allows us to define custom sorting behavior. The idea is simple: specify that 0 should be treated as a larger number, thus pushing it to the end of the ordered list. Here's how you can do this:

In this code snippet:

The CASE statement checks if the order field equals 0. If it does, it evaluates that as 0 for sorting (which will be placed at the end because of DESC).

Otherwise, it evaluates to 1, allowing those values to appear first when sorted in ascending order.

Alternative Approaches

If you prefer to separate the logic for clarity, you can also split the sorting lines:

Or, you can combine it in a slightly different way using orderByDesc:

Conclusion

Sorting collections in Laravel Eloquent can be tricky when dealing with 0 and null values. However, with the help of the CASE statement, you can easily customize the behavior of your orderBy to ignore these undesired values effectively. By following the methods outlined above, you can ensure that your collections are sorted in a manner that makes sense for your application's needs.

No more unexpected ordering – just clean, structured, and predictable results! Happy coding!
