How to Send Data Through AJAX to Another Controller in Laravel

Sending data through AJAX to another controller in Laravel can seem daunting, especially when dealing with dynamic forms. In this guide, we'll break down the entire process and explain how to successfully implement AJAX requests in your Laravel application.

Understanding the Problem

You might encounter a situation where you wish to send data from a form, but instead of a traditional form submission, you want to use AJAX for a more dynamic and smoother user experience. In our example, we have a form that includes multiple inputs for student names and roll numbers, and we need to send this data asynchronously to a specific route that's handled by a controller in Laravel.

Setting Up the Route

In your Laravel application, you first need to define a route that accepts the POST request from your AJAX call. Here’s a sample route setup:

Creating the HTML Form

Here's how your HTML form will look. It contains fields for class name, class teacher, and a dynamic table to input multiple student names and roll numbers.

Implementing the AJAX Call

To send the data through AJAX, you can create a separate button for AJAX submissions or modify your existing submit button to prevent the default form submission. Here’s how to do it with a dedicated AJAX button:

Option 1: Separate AJAX Button

Add a button to trigger the AJAX call:

Then use the following JavaScript to handle the AJAX request:

Option 2: Modify Submit Button

If you want to utilize the default submit button but still send the data through AJAX, you'll need to prevent the form's normal submission like this:

Conclusion

By following the steps outlined above, you can easily send data through AJAX to another controller in Laravel. Using AJAX not only enhances the user experience by avoiding page refreshes but also allows handling data dynamically and smoothly. Whether you decide to use a separate AJAX button or modify the submit behavior of your form, the key is to ensure your form data is serialized correctly and sent to the appropriate route.

Feel free to experiment with the code and adjust it according to your specific needs! Happy coding!
