How to Create an Entity in Symfony 5 Database with AJAX and Without a Form

When working with Symfony 5, one common scenario developers encounter is the requirement to add or modify database records without the overhead of web forms. If you're looking for a way to create an entity in your database using AJAX without displaying a form, this guide is just for you! In this guide, we'll walk you through the process step by step. Let's dive right in!

Understanding the Problem

You might have a scenario where you have all necessary data to create a new entity, but you do not want to display a form. This can lead to confusion, especially if you're used to the more traditional methods of handling forms with Symfony. The good news is that you can indeed achieve this using AJAX!

The Solution: Creating an Entity Using AJAX in Symfony

Step 1: Update LivreController.php

The first step is to set up your controller to handle the AJAX request. Instead of utilizing a form, we'll directly handle the incoming JSON data. Here's how you can accomplish this:

Step 3: Testing the Implementation

Open your web application and click the button associated with the livreCreatorButton.

Check the console for the success message confirming that your new entity has been added!

Conclusion

Creating a database entity in Symfony 5 using AJAX without a form is not only achievable but can streamline your application's user experience. Following the steps outlined in this guide, you'll be able to add entities directly with the click of a button, simplifying your workflow. If you run into any issues or have any questions, feel free to reach out or explore further in the Symfony documentation. Happy coding!
