The Magic Behind Your WordPress Post: A Beginner’s Guide to Databases

Whether you’re a new blogger or a small business owner looking to establish an online presence, WordPress is an excellent tool to share your content and ideas. In this blog post, we’re going to peel back the curtain on WordPress and explain what happens when you publish a post. We’ll also explore how WordPress stores your data in a database, and how it retrieves this information when someone visits your site.

Understanding WordPress Publishing

The heart of WordPress lies in its user-friendly dashboard. From here, you can create and manage your content with ease. Let’s say you want to create a new blog post. You’d navigate to “Posts” on the left-hand side and click “Add New.”

Here, you can input your title, write your content, add images, and more. Once you’re satisfied with your post, you hit that enticing “Publish” button. But what happens when you do?

When you click “Publish,” WordPress takes your post and breaks it down into pieces, such as the title, the content, the author, and the publication date. It then sends this data to a database.

Diving into WordPress Databases

Imagine a database like a giant, ultra-organized filing cabinet. It holds all the essential information for your website, neatly organized for easy access.

WordPress uses a type of database called MySQL. Within this database, information is stored in tables, kind of like spreadsheets with rows and columns.

When you publish a post, WordPress stores the data in these tables. For instance, the title, content, and author are stored in a table called ‘wp_posts,’ while the categories you’ve assigned to the post are stored in another table called ‘wp_terms.’

The Journey of a Post: From Database to Viewer

So, how does this information get from the database to your visitor’s screen when they click on your post? Here’s where the magic happens.

When someone visits your site, WordPress uses a scripting language called PHP to ask the MySQL database for the information it needs. It’s kind of like a librarian asking for a specific book in the library.

Once the database provides the information, PHP takes that data and uses it to build a webpage. It transforms the raw data into HTML, the language that web browsers can interpret and display.

So, when a visitor clicks on your post, WordPress quickly retrieves the relevant data from the database, constructs an HTML page, and serves this to the visitor’s browser. All of this happens in a fraction of a second, creating a seamless experience for your readers.

Styling Your Post with the WordPress Template System

When it comes to displaying your content, WordPress isn’t just about retrieving it from the database. It also cares deeply about how that content looks to your visitors. This is where the WordPress template system comes into play.

In simple terms, a template in WordPress is a file that dictates how a certain part of your website looks. WordPress has many different templates, each controlling a different section of your site. For example, there’s a template for your homepage, another for your blog posts, and even one for your category pages.

When you choose a WordPress theme for your website, you’re essentially choosing a package of templates that have been designed to work well together. These templates are filled with HTML and CSS, the coding languages that define the structure and style of web pages.

So, when a visitor lands on one of your posts, here’s what happens:

  1. WordPress retrieves the content of the post from the database, as we’ve discussed before.
  2. It then looks at the template file for single posts (usually called single.php or single.html).
  3. This template file contains placeholders where your content should go (like the title, the content, and the author).
  4. WordPress takes the retrieved content and inserts it into these placeholders.
  5. The HTML and CSS in the template file then style this content, defining things like font, color, layout, and more.

The result? Your raw content is not only retrieved but also beautifully styled, providing a visually pleasing experience for your readers.

This combination of powerful content retrieval and flexible styling is part of what makes WordPress such a popular choice for websites of all kinds.


Congratulations! You now understand the basics of what happens when you publish a post in WordPress, how that data is stored, and how it’s retrieved when someone visits your site. It’s quite a journey, isn’t it?

We encourage you to keep exploring WordPress and its powerful database system. The more you understand, the more effectively you can use this platform to share your content with the world.
