# Solving the Mystery: Undefined Variable Errors in Laravel 5.2 Validation
Welcome to the world of Laravel! As you are diving into building robust applications, you will inevitably encounter tricky little errors, especially when dealing with form validation and presentation logic. The issue you are facing—getting an "Undefined variable: \$errors" in your Blade template—is extremely common for newcomers. It doesn't signal a bug in the code itself, but rather a misunderstanding of how Laravel passes data and error states between the Controller and the View.
As a senior developer, I can assure you that this is a classic scenario rooted in data flow. Let’s break down exactly why this happens with your setup using Laravel 5.2, and more importantly, show you the correct, idiomatic way to handle validation errors gracefully.
## The Root Cause: Where Do Validation Errors Live?
When you use Form Requests (like your `CreateArticleRequest`) in conjunction with a Controller method, Laravel handles the validation automatically. If the request fails validation (e.g., a field is missing or doesn't meet the `min:3` rule for the title), the validation process stops execution and populates an `$errors` collection on the Request object.
The problem arises when you try to access this error data in your view (`add.blade.php`) without explicitly ensuring that the necessary context is passed along. Simply referencing `$errors` directly in the view doesn't automatically make it available unless it was explicitly made available in the controller or via the request object itself.
## The Correct Approach: Passing Errors to the View
The key to solving this is understanding that the validation errors are attached to the request instance. You need to ensure that when you render the view, you pass the request object (or its error state) to the view.
In your specific case, since you are handling a form submission, the errors should be accessible within the context of where you display the form.
### 1. Reviewing Your Controller Logic
Your controller logic is mostly correct for saving data:
```php
// ArticlesController.php
public function create_article_row(CreateArticleRequest $request){
// If validation fails, execution stops here, and the error object exists within $request.
Article::create($request->validated()); // Use validated() for cleaner access
return redirect('articles/');
}
```
While this handles saving, it doesn't inherently solve displaying errors on a *failed* submission because the view is being rendered outside of that specific failure context.
### 2. Displaying Errors in the Blade View
To correctly display validation errors, you should access the `$errors` property directly from the request object you are using to handle the input. If you are rendering a form that failed validation, you must ensure the request object is available.
If you are displaying an error message *after* a submission attempt, you typically use Blade's `@error` directive, which is specifically designed for this purpose and works beautifully with Form Requests.
Here is how you should structure your `add.blade.php` file to display errors correctly:
```blade
{{-- add.blade.php --}}
