How to Use SweetAlert After a PHP Redirect: A Step-by-Step Guide

Using SweetAlert to enhance user experience by displaying alerts is a common practice in web development. However, integrating it correctly after a PHP redirect can pose a challenge, especially when handling failed login attempts. If you're struggling to achieve this in your project, you are in the right place! In this guide, we will tackle how to display a SweetAlert notification after a user fails to log in.

Understanding the Problem

After submitting a login form, you want to notify the user if their login attempt fails. This typically involves checking the user's credentials against stored data. If the credentials don’t match, you can redirect them back to the login page and display an error alert.

Here’s a snippet of code that illustrates this possible scenario:

In this example:

A successful login redirects to the store page.

A failed login redirects to the login page while passing a login=false parameter.

Implementing the Solution

To achieve the desired result, we will set up SweetAlert in index.php and check for the redirect parameter to display an alert when the user comes back to the page after a failed attempt. Here's how to do it step-by-step.

Step 1: Include Required Libraries

Make sure to include the jQuery library and SweetAlert in your document. Here’s what your <head> section should look like:

Step 2: Detect the Redirect Parameter

In the body of your index.php, you’ll check whether the login parameter is set to false. If it is, you’ll invoke the SweetAlert library to show an alert to the user.

Here is the code snippet for this:

Step 3: Customize Your Alert

You can customize your alert with different titles, messages, and icons as needed. The code above showcases a basic alert with a title indicating a failed login.

Bonus: Handling AJAX Requests
