Why Pagination with custom queries in Wordpress? - Purpose & Use Cases

The Big Idea

Discover how to make your WordPress site load faster and keep visitors happy with easy pagination!

The Scenario

Imagine you have a blog with hundreds of posts and you want to show only 10 posts per page. You try to write your own code to fetch posts and split them into pages manually.

The Problem

Manually handling pagination means writing complex SQL queries, managing offsets, and keeping track of page numbers. It's easy to make mistakes, slow down your site, and confuse users with broken navigation.

The Solution

Pagination with custom queries in WordPress lets you easily fetch exactly the posts you want and split them into pages automatically. It handles all the tricky parts like counting total posts and generating page links.

Before vs After

✗ Before

$offset = ($page - 1) * 10;
$results = $wpdb->get_results("SELECT * FROM wp_posts WHERE post_status = 'publish' AND post_type = 'post' LIMIT 10 OFFSET $offset");

✓ After

$query = new WP_Query(['posts_per_page' => 10, 'paged' => $page]);
while ($query->have_posts()) { $query->the_post(); /* show post */ }

What It Enables

You can create smooth, user-friendly navigation through large sets of posts without worrying about complex database details.

Real Life Example

A news website showing 10 latest articles per page with next and previous buttons, letting readers browse easily without loading all articles at once.

Key Takeaways

Manual pagination is complex and error-prone.

WordPress custom queries simplify fetching and paginating posts.

This improves site speed and user experience.
