Here we provided Laravel Insert, Update, View Source Code. Laravel is a PHP web framework that can be used to create powerful and efficient web applications. This step-by-step explanation assumes you’re starting from scratch and includes setting up Laravel, creating a model, controller, routes and views.

Prerequisites

PHP (>= 8.1 recommended)
Composer installed
MySQL or another database
Basic understanding of PHP and MVC concepts

Laravel Insert, Update, View Source Code

Here is some sample source code for performing CRUD (Create, Read, Update, and Delete) operations in Laravel:

Insert:

    //View all tasks
    public function index()
    {
        $tasks = Task::all();
        return view('tasks.index', compact('tasks'));
    }

    //Create a new task
    public function create()
    {
        return view('tasks.create');
    }

    //Store a new task
    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required|string|max:255',
            'description' => 'nullable|string',
        ]);

        Task::create([
            'title' => $request->title,
            'description' => $request->description,
            'is_completed' => $request->has('is_completed'),
        ]);

        return redirect()->route('tasks.index')->with('success', 'Task created successfully.');
    }

    //Show form to edit a task
    public function edit(Task $task)
    {
        return view('tasks.edit', compact('task'));
    }
    
    //Update a task
    public function update(Request $request, Task $task)
    {
        $request->validate([
            'title' => 'required|string|max:255',
            'description' => 'nullable|string',
        ]);

        $task->update([
            'title' => $request->title,
            'description' => $request->description,
            'is_completed' => $request->has('is_completed'),
        ]);

        return redirect()->route('tasks.index')->with('success', 'Task updated successfully.');
    }

It is worth noting that this code uses Eloquent, which is Laravel’s ORM (Object-Relational Mapping) that allows you to interact with your database using an object-oriented syntax. The User model represents the users table in the database, and the create, find, all and save methods are provided by Eloquent.

It is also important to note that the above code is just a sample and it should be used only as a reference. It’s not complete and it’s missing some important parts such as validation, exception handling, and security.

Software Requirements

Framework: Laravel
Programming Language : PHP
Database: MySQL

Functionality

Insert: The create method shows a form, and the store method validates and saves a new task to the database.
Update: The edit method displays a form pre-filled with the task’s data, and the update method validates and updates the task.
View: The index method retrieves all tasks and displays them in a table.

Notes

Validation: The controller uses Laravel’s validation to ensure the title is provided and meets length requirements.
CSRF Protection: The @csrf directive in forms protects against cross-site request forgery.
Method Spoofing: The @method(‘PUT’) directive allows the update form to send a PUT request.
Bootstrap: Used for basic styling. You can customize the views further with CSS or other frameworks.
