For optimized developer stack, I have installed my Laravel application on a Cloudways: Managed Cloud Hosting Platform managed server. You can also sign up for a free Cloudways: Managed Cloud Hosting Platform Web Hosting for PHP easily and can set up your application within a few minutes.

Step 1: Laravel CRUD Database Configuration

Using Cloudways: Managed Cloud Hosting Platform, the MySQL database configuration variables are already set up in .env File and database.php file. But if you want to use another MySQL database then you could do so by updating its default configuration in both files.

CRUD Operations in Laravel PHP Framework

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=
DB_USERNAME=root
DB_PASSWORD=

Step 2: Create Employee Table

And then successfully configuring the MySQL database, now we will move towards creating a employee table. But before creating a employee table, first create the migration for a Database table by executing the below command:

php artisan make:migration create_employees_table

And then update the below source code into created migration file.

public function up()
{
Schema::create('employees', function (Blueprint $table)
{
$table->increments('id');
$table->string('title');
$table->text('description');
$table->timestamps();
});
}

/**
* Reverse the migrations.
* @return void
*/
public function down()
{
Schema::dropIfExists('employees');
}

And then run the php artisan migrate command to setup table into the MySQL database.

Step 3: Migration with Create model or controller

And then create the migration with model and controller of a specific table by just entering the below given command in SSH terminal.

php artisan make:model Employee -mcr

Step 4: Setup Model

And then open the employee model and copy & paste the below array in employee.php file.

protected $fillable = [ 'title', 'description'];

Step 5: Controller

After successfully setting up model, now open the employeeController.php file and change all the functions according to their function names like update store, edit or destroy functions.

Employee Controller index()

Simple Copy and Paste the below source code into index() function.

public function index()
{
$employees = Employee::all();
return view('employees.index',compact('employees',$employees));
}

Employee Controller create()

After that copy the below code and paste into create() function.

public function create()
{
return view('employees.create');
}

Employee Controller store()

To insert Store data into the MySQL database, copy paste the below source code into store function.

public function store(Request $request)
{
// Validate
$request->validate([
'title' => 'required|min:3',
'description' => 'required',
]);
$employee = Employee::create(['title' => $request->title,'description' => $request->description]);
return redirect('/employees/'.$employee->id);
}

Employee show()

public function show(Employee $employee)
{
return view('employees.show',compact('employee',$employee));
}

Employee Edit ()

public function edit(Employee $employee)
{
return view('employees.edit',compact('employee',$employee));
}

Employee Destroy()

public function destroy(Request $request, Employee $employee)
{
$employee->delete();
$request->session()->flash('message', 'Successfully deleted the employee!');
return redirect('employees');
}

Step 6: Create View Laravel – CRUD

To complete the layout view of CRUD(insert update delete), create the view files with the name create.blade.php, edit.blade.php, index.blade.php, and show.blade.php. Also Use Twitter Bootstrap v4 for creating a user friendly layout views consistent.

Create.blade.php

@extends('layout.layout')
@section('content')
<h1>Add New Employee</h1>

<hr />

<form action="/employees" method="post">{{ csrf_field() }}
<div class="form-group"><label for="title">Employee Title</label>
<input id="employeeTitle" class="form-control" name="title" type="text" /></div>
<div class="form-group"><label for="description">Employee Description</label>
<input id="employeeDescription" class="form-control" name="description" type="text" /></div>
@if ($errors->any())
<div class="alert alert-danger">
<ul>
 	<li style="list-style-type: none;">
<ul>@foreach ($errors->all() as $error)
 	<li>{{ $error }}</li>
</ul>
</li>
</ul>
@endforeach

</div>
@endif
<button class="btn btn-primary" type="submit">Submit</button>

</form>@endsection

Step 7: Show View

@extends('layout.layout')
@section('content')
<h1>Showing Employee {{ $employee->title }}</h1>
<div class="jumbotron text-center">

<strong>Employee Title:</strong> {{ $employee->title }}
<strong>Description:</strong> {{ $employee->description }}

</div>
@endsection

Step 8: Edit View

@extends('layout.layout')
@section('content')
<h1>Edit Employee</h1>

<hr />

<form action="{{url('employees', [$employee->id])}}" method="POST"><input name="_method" type="hidden" value="PUT" />
{{ csrf_field() }}
<div class="form-group"><label for="title">Employee Title</label>
<input id="employeeTitle" class="form-control" name="title" type="text" value="{{$employee->title}}" /></div>
<div class="form-group"><label for="description">Employee Description</label>
<input id="employeeDescription" class="form-control" name="description" type="text" value="{{$employee->description}}" /></div>
@if ($errors->any())
<div class="alert alert-danger">
<ul>
 	<li style="list-style-type: none;">
<ul>@foreach ($errors->all() as $error)
 	<li>{{ $error }}</li>
</ul>
</li>
</ul>
@endforeach

</div>
@endif

<button class="btn btn-primary" type="submit">Submit</button>

</form>@endsection

Step 9: Delete

<form action="{{url('employees', [$employee->id])}}" method="POST"><input name="_method" type="hidden" value="DELETE" />
<input name="_token" type="hidden" value="{{ csrf_token() }}" />
<input class="btn btn-danger" type="submit" value="Delete" /></form>

Step 10: Routes

Here, I need to add All the required route for Employee crud application. so open your “routes/web.php” file and add below route.

Route::get('/', function () {
return view('welcome');
});
Auth::routes();
Route::get('/home', '[email protected]')->name('home');
Route::get('/create','[email protected]');
Route::get('/employee', '[email protected]');
Route::get('/edit/employee/{id}','[email protected]');
Route::post('/edit/employee/{id}','[email protected]');
Route::delete('/delete/employee/{id}','[email protected]');
