How to Display Author Names from the Author Category in Prestashop 1.7

Setting up an online book store using Prestashop can be exciting, especially when you want to showcase authors as an integral part of your store. In this guide, we will address a common issue many developers face: displaying author names from a category you've created in your Prestashop 1.7 store. This issue can be perplexing, but fear not—this guide will break down the steps to get it done correctly.

The Problem

You have set up an "Authors" category and included several authors as subcategories under it. Once you implemented a PHP function in the classes/product.php file to retrieve these author categories along with their names, you attempted to display them in the product.tpl template file. However, you are not seeing the author names appear on the front end of your site even after clearing the cache.

The Solution

Let’s explore how to resolve this problem step by step.

Step 1: Verify the PHP Function

The first thing we need to check is the PHP function you have added in classes/product.php. Here is the initial code provided:

Important Note

There was a small issue in the SQL query where it checked for cl.id_parent instead of the correct parameters for showing the parent category. Make sure that all references are appropriately set as in the provided query above.

Step 2: Update the Template File

Next, let's assess what you put in the product.tpl template file. The original attempt was:

Why This Works

Correct Syntax: We retained valid syntax while escaping HTML for security and usability.

No Structure Changes: The semantic structure remains, ensuring better SEO performance and compatibility.

Debugging: Utilize tools like var_dump($product) carefully to diagnose what variables are available without exposing sensitive data.

Step 3: Clear Cache Again

After applying these changes, it’s essential to clear the Prestashop cache again. Go to Performance and regenerate cache to ensure that your modifications are reflected on the front end.

Conclusion

By following these steps, you should now successfully display author names from the Author category in your Prestashop 1.7 book store. Keeping code clean and checking SQL queries for correct parameters can save you a lot of time in troubleshooting future issues. Happy coding and good luck with your online book store!
