Tackling the Prestashop 1.7 Module Front Controller 404 Error

Are you experiencing frustrating 404 errors when trying to access your new Prestashop 1.7 module front controller? You’re not alone, as many developers face this issue during their module development journey. In this guide, we will help you understand the common causes of this problem and provide a clear, practical solution to get your module up and running.

Understanding the Problem

While developing a module for Prestashop 1.7, it is common to encounter a 404 error when attempting to access a front controller. This typically indicates that the requested page cannot be found, meaning the server was unable to locate the URL you provided. In the scenario outlined, the developer calls the following URLs:

http://localhost/modules/cbd_calculator/display

http://localhost/index.php?fc=module&module=cbd_calculator&controller=display

Both links result in a 404 error, indicating the path to the front controller is likely incorrect.

Analyzing the Solution

When examining the code provided, the issue stems from the file path of the front controller class. Below is a breakdown of the solution that corrects the path to the display.php file.

Identifying the Error in the Path

In the original code, the path to the front controller was incorrectly designated as:

However, in Prestashop, the correct structure should be:

Steps to Fix the Error

To resolve the 404 error, follow these steps:

Rename the Directory: Ensure that the directory for the front controller is named controllers, not controller. This involves changing:

From: controller/front/display.php

To: controllers/front/display.php

Verify File Structure: After correcting the directory name, double-check the overall structure of your module to ensure that all files are in their correct locations.

Clear Cache (if necessary): Sometimes, issues can arise from cached information. Clear the cache in your Prestashop environment to ensure the changes take effect. You can do this by navigating to Advanced Parameters Performance in the admin dashboard and clearing the cache.

Testing the Changes

After making the necessary changes to the directory structure, you can now test the URLs again:

Visit: http://localhost/modules/cbd_calculator/display

Or alternatively: http://localhost/index.php?fc=module&module=cbd_calculator&controller=display

If everything is implemented correctly, you should now see the content intended for display without encountering a 404 error.

Conclusion

In summary, encountering a 404 error when working with a Prestashop 1.7 module front controller often comes down to an incorrect directory structure. By ensuring the front controller is placed within the correctly named controllers folder, most developers can resolve this issue with ease.

If you're still facing challenges, don't hesitate to revisit the entire module setup and ensure each part is in the proper order. Happy coding, and may your Prestashop experience be smooth and enjoyable!
