Resolving Call to undefined method App\User::id() Error in Laravel

Have you ever encountered the frustrating error message saying "Call to undefined method App\User::id()" when working with Laravel? If you’re receiving this error, you're not alone. This common issue can arise when you're developing functionalities that rely on user authentication and you're chaining methods incorrectly in your helper classes. In this post, we will dive deeper into understanding why this error occurs and, more importantly, how to fix it.

Understanding the Problem

When using Laravel's authentication system, accessing the authenticated user's ID should be straightforward. However, if you attempt to call the id() method on the user object, you might run into this error. The root of the issue is in how you access the user ID from the Auth facade in your custom helper function. In your current implementation, you are mistakenly trying to use a method called id() instead of accessing the property directly.

The Code Snippet That Causes the Issue

Correcting the User ID Access

To resolve this error, you simply need to change the way you access the user ID. You have two options:

Remember, using $user_id = Auth::user()->id; or $user_id = Auth::id(); will help you fetch the authenticated user's ID without any hiccups.
