How to Display Articles in a Specific Order Using Laravel 8 Pagination

If you're working with Laravel 8 and need to display articles based on their publication_date, you might run into challenges when trying to paginate results without using the built-in paginate method. This guide will walk you through the process step-by-step, ensuring you can effectively show 8 articles per page while dynamically incorporating your custom conditions.

The Problem

Your goal is to show a list of articles from your MySQL database, ordered by their publication date, and only display 8 articles per page. You also want to remove the desc_id column from your model's calculations but require it to paginate your results effectively.

A sample query modification was attempted, but it resulted in an empty $articles array. Let’s delve into that code and understand how to tweak it.

The Solution

Step 1: Modify Your Query

The first adjustment you need to make is to your Query Builder in the controller. You have the right structure in mind but forgot a key method at the end of your query. To retrieve the records as an array, you need to include a .get() method. Here’s how to do it:

Step 2: Understanding Pagination Logic

Setting Up Pagination Variables:

Define the current page using Request::segment(2), defaulting to 1 if null.

Calculate the maximum and minimum desc_id based on the current page.

Fetching Articles:

Use the get() method to execute the query and retrieve the actual articles. This was the missing piece in your initial implementation.

Filtering Articles:

Filter $articles_show based on their desc_id to include only those articles that fall within the specified range.

Step 3: Updating the View

In your Blade template, you are correctly iterating over the $articles array. Ensure you have proper checks in place, such as checking if $articles is not empty before the loop starts, to prevent any potential errors.

Conclusion

By following these adjustments, you will be able to paginate your articles based on their publication date effectively while controlling the output in Laravel 8. This method allows you to manage how the articles are presented without relying solely on the paginate() method, improving flexibility in your application.

Now that you have a solid understanding of the changes needed, apply these adjustments, and you'll see the articles display correctly as intended! Happy coding!
