what is the update method in laravel 5.4 crud?

Title: Understanding the Update Method in Laravel 5.4 CRUD Introduction: In your quest for developing a robust web application using Laravel Framework, you must know how to handle create, read, update, and delete (CRUD) operations efficiently. The update method is an important component of handling this process. Let's delve into the concept. Update Method in Detail: The update operation is necessary when a user wants to modify existing data in your database. It can be done through HTTP PUT or PATCH methods, depending on the Laravel version you are working with. In Laravel 5.4, only the PUT method is supported for updating records. For other versions, you might need to handle both PUT and PATCH requests separately. The update method generally involves retrieving the data, processing user input from the request body, updating the database with the updated values, and then redirecting the user back to a related page. Let's look at a sample code for updating data:

public function update(Request $request, $id) {
    // Retrieve the article using the given ID from the database
    $article = Article::find($id);

    // Process request input and assign updated values to variables
    $content = $request->input('content');
    $live = (boolean)$request->input('live');
    $post_on = $request->input('post_on');

    // Update the article's data in the database
    $article->update([
        'user_id' => auth()->id(),
        'content' => $content,
        'live' => $live,
        'post_on' => $post_on
    ]);

    // Return a relevant response or redirect to the appropriate page
    return redirect('/articles');
}

In this code: - The update action is called using Laravel's route model binding with the `find()` method. - User input from the request body (content, live status and post_on) is processed and assigned to variables. - To ensure only authenticated users can update articles, you can use Laravel's `auth()->id()` function in the code. - The updated article is saved into the database using the `update()` method, taking an array of new attribute values as arguments. - Finally, a redirect is issued to redirect back to the same page or any other relevant location upon successful execution. Conclusion: As you can see from this blog post, the update method in Laravel's CRUD system is crucial for efficiently modifying existing records within your database. To grasp it fully, you need both knowledge of Laravel framework and expertise in writing robust application logic.
