17 May 2019: This article and the code were updated for PHP7 compatibility.
In my tutorial Build a CMS in an Afternoon with PHP and MySQL, I showed how to build a simple but useful content management system with PHP and MySQL. I also showed how to extend the CMS to allow article categories.
In this tutorial, you’ll look at another way to extend the CMS. You’ll take the original CMS code, and modify it so that the administrator can upload an image for each article. Then, when a visitor views an article page, the CMS will display the image at the start of the article. In addition, our CMS will generate a smaller thumbnail version of each article image, and display this thumbnail next to each article headline in the homepage and article archive pages.
You can see the finished result by clicking the View Demo link above. Notice the thumbnail images next to each article headline. Click a headline or thumbnail to view the corresponding article, along with the full-size article image.
