How To Make Validations With Requests In Laravel 8?

Creating user accounts is a common feature in web applications, and Laravel provides powerful tools to help manage this process efficiently. However, users often encounter issues when trying to validate inputs, especially if they are new to the framework. In this guide, we will discuss how to implement input validations for user creation in Laravel 8, using a feature called Form Requests. We'll also address a common error message regarding validation methods that many developers face.

The Problem

When implementing input validation in Laravel, you can easily run into unexpected errors if there's a typo in your code. A common occurrence is when you see an error message like this:

This indicates that your validation rules are not set up correctly, leading Laravel to look for a non-existent method called validateRequierd. But don't worry; this is a simple fix!

The Solution

Based on the code you provided for your UserCreateRequest, the issue likely stems from a typo in the validation rules. The correct validation rule is required, but it looks like it was mistakenly written as requierd. Here’s how to correct it and implement validations properly.

Step 1: Define Validation Rules

In your UserCreateRequest.php, ensure that you have the correct validation rules. Here’s the corrected code:

Step 2: Implement the Store Method

Step 3: Testing Your Implementation

Once you've made these corrections, it's crucial to thoroughly test your validation implementation by sending various requests to your endpoint. Ensure that:

Requests with missing or invalid name, email, and password fields return appropriate validation error messages.

Valid requests successfully create user accounts and return a 201 Created status.

Conclusion

By following these steps, you should no longer encounter the validateRequierd error. Typos are common in programming; they serve as good reminders to stay vigilant with our code. Laravel’s request validation system proves incredibly useful in maintaining data integrity and enhancing user experience.

If you still encounter issues or need further clarification on Laravel's input validation, feel free to ask for help. Happy coding!
