My PHP Script to see WordPress Posts and Views ordered by Views

This article shows the code for my PHP program posts_and_views.php that you can see at the bottom of in the Quick Selection bar.

Page rendered of all my Published Posts sorted by Views

So I wrote this small PHP Code to display the number of Post Views recorded in my WordPress Database, sorted by Views in descending order.

In other words, sorted from Most Viewed.

Please note: In order to track the post views I use the excellent plugin WP-PostViews by Lester ‘GaMerZ’ Chan

Here is the code for posts_and_views.php

As you can see I use wp-config.php file to get the Database Settings (username, password, database) but I don’t use the WordPress Engine, it is just a stand alone PHP. So I wrote my own function to get the slug based on the category name. I believe the slug for it is in the Database and I could have added this as a SubQuery with JOINs, which would be better, but I wanted to keep the Database workload lightweight and especially, I did not want to invest more time investigating how the get the slug.

As I tested my function I didn’t find any Category failing but I saw that I had the Category Storage repeated in two different structure tree in Categories, and I will only always link to just the first one (So I was not linkin to the slug storage-2). I fixed that Category that I found repeated but to be honest if this script was a commercial solution or an Open Source solution properly maintained rather than just a sample, I would update it to have Categories and Tags’ slugs coming from the Database.

I would probably make it work with a Cron that would generate a cached page, updated every hour or every ten minutes. I did this in other projects I worked or in my PHP Framework Catalonia Framerwork.

But honestly, the load of the page does not justify a major effort in optimizing here, in this case.
