View

The View in Model-View-Controller (MVC)

The View is the presentation layer in the MVC architecture. It is responsible for displaying data from the Model in a user-friendly format.

Main Responsibilities of the View

✅ Displaying Data: Shows information from the Model (e.g., a list of blog posts).
✅ Reacting to User Interactions: Accepts user input and sends it to the Controller.
✅ Formatting & Layout: Structures content using HTML, CSS, or templating engines (e.g., Laravel Blade or Twig).
✅ Avoiding Business Logic: Contains only presentation logic, not data processing.

How Does the View Work in MVC?

1. The user sends a request (e.g., "Show all blog posts").
2. The Controller calls the Model to retrieve the data.
3. The Model returns the required data.
4. The View receives the data from the Controller and displays it.

Example: Blog System (View in Laravel Blade)

<!-- resources/views/blog/index.blade.php -->
@extends('layouts.app')

@section('content')
    <h1>Blog Posts</h1>
    @foreach ($posts as $post)
        <div>
            <h2>{{ $post->title }}</h2>
            <p>{{ $post->content }}</p>
        </div>
    @endforeach
@endsection

🔹 @foreach: Loops through the list of blog posts and displays them.
🔹 {{ $post->title }}: Outputs the title of the blog post.

Conclusion

✔ The View is responsible for presentation but does not process data.
✔ It ensures a clear separation between logic and display.
✔ Using templates or frontend technologies (e.g., Vue.js, React), the View can be dynamically rendered.
