How to Dynamically Update Total Orders in Laravel with jQuery

In Laravel applications, displaying dynamic data is essential for an interactive user experience. One common requirement is to show real-time updates based on user input, such as the total number of orders filtered by date. This guide will guide you through the process of dynamically displaying the total orders in a Laravel Blade view using jQuery and AJAX.

Problem Overview

In a typical Laravel application, you might find yourself wanting to update the number of total orders displayed on the screen as the user selects different dates. In this case, you have a controller that fetches the total number of daily orders from an API and displays it on your Blade template. However, after implementing a date picker, the total orders do not update correctly when the selected date changes. Let’s explore how to fix this issue.

Setting Up Your Blade View

Initially, here’s how your Blade template might look:

Implementing the AJAX Call

To update the total orders count based on the selected date, you will need to make an AJAX call when the date changes. Here’s how you can do that using jQuery:

JavaScript Code for AJAX Request

Explanation of Each Section

Event Listener: The code listens for a change event on the date input.

AJAX Setup: Sets the CSRF token for security, required for Laravel applications.

AJAX Call:

Type: Defines the method as GET.

URL: Specifies the endpoint to receive the request.

Data: Sends the selected date from the date picker.

Success Function:

Receives the response from the server.

Updates the -tot_o span with the total orders count received in the response using the text() method.

Updating the Controller

In your controller method, ensure you return the data correctly as JSON:

This ensures that when the AJAX call is successful, it correctly retrieves the total number of orders from the JSON response and updates the display on the page.

Conclusion

With this setup, you can now easily update the total number of orders dynamically based on the date selected by the user. This integration of Laravel with jQuery and AJAX not only enhances the user experience but also provides a modern approach to data handling within web applications.

By following these steps, you are now equipped to implement dynamic updating of UI elements in Laravel, making your application more interactive and user-friendly.
