Introduction

When working with web applications in Laravel, proper validation is essential to ensure that users provide the correct information. However, sometimes you may want to streamline the error messages returned to users, displaying only the messages without their corresponding field names or codes. If you're struggling with this in your Laravel application, you've come to the right place!

In this guide, we'll explore how to configure Laravel's validation system to show only the error messages, providing users with a cleaner and more straightforward experience. Let's dive in!

Understanding the Problem

When using Laravel's built-in validation system, the default behavior when validation fails is to return an error response that includes both the error messages and the associated field names. For instance, if a user's name exceeds a specified length, the error message might look something like this:

This format may not always be user-friendly. A cleaner approach would simply show the message as:

Solution Overview

To achieve this, we'll modify the default behavior in the controller and enhance the view where the error messages are displayed. Below is a step-by-step breakdown of the solution.

Step 1: Using withErrors Instead of with

In your controller, instead of using the with method to pass your error messages to the session, use withErrors. This method is specifically designed for handling validation error messages. Here's how to implement it:

In this code snippet, when the validation fails, we redirect back with the error messages that will be stored in the session.

Step 2: Modifying the View to Display Only Error Messages

Next, we need to adjust the view file where the errors are displayed. Instead of outputting the field name associated with the errors, we'll loop through the errors array and display each message in a more user-friendly way. Use the following code in your view file:

Explanation of the View Code

Check for Errors: The @ if($errors->any()) directive checks if there are any errors present in the session.

Display Errors: If errors are found, we create a div with a class of alert alert-danger (for styling) and iterate over each error in the $errors object. Each error is displayed as an item in an unordered list.

Conclusion

By following the steps outlined above, you can easily modify your Laravel application to display only the error messages without the field names or codes. This not only enhances the user experience but also helps maintain a clean interface.

Implementing withErrors and customizing the error display logic makes your application more user-friendly, allowing users to understand the issues with their input without confusion.

Feel free to implement these changes in your Laravel projects and enjoy a more streamlined error handling experience!
