LARAVEL CRUD | MYSQL DATABASE APPLICATION
OBJECTIVE: To create a simple web application that will connect to mysql database and will perform
basic CRUD operation.
OUTPUT:
TASKS:
1. CREATE THE NEW LARAVEL PROJECT WITH FILENAME: lastname-crud
composer create-project laravel/laravel lastname-crud
2. DATABASE SET-UP
a. Create a database on phpMyadmin named student_crud
b. Configure the database on the laravel folder > .env file
c.
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=student_crud
DB_USERNAME=root
DB_PASSWORD=
3. CREATE TABLE AS MIGRATION IN LARAVEL_
php artisan make:migration create_students_table
* From phpMyadmin, check if the database students is successfully created after the
migrations . You should be able to see the students table.
* From the laravel file, check if create_students_table.php exists.
4. IN LARAVEL FILE, database>migrations> OPEN create_students_table.php file, THEN CREATE THE
FOLLOWING FIELDS:
$table->string(‘name’);
$table->string(‘address’);
$table->string(‘mobile’);
⮚ CODE SHOULD BE THE CODES BELOW:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

{
public function up(): void
{
Schema::create('students', function (Blueprint $table) {
$table->id();
$table->string("name");
$table->string("address");
$table->string("mobile");
$table->timestamps();
});
}
public function down(): void
{
Schema::dropIfExists('students');
}
};
⮚ SAVE THE CHANGES MADE

public function store(Request $request): RedirectResponse
{
$input = $request->all();
Student::create($input);
return redirect('student')->with('flash_message',

public function show(string $id): View
{
$student = Student::find($id);
return view('students.show')->with('students',

}
public function edit(string $id): View
{
$student = Student::find($id);
return view('students.edit')->with('students',
$student);
}
public function update(Request $request, string $id):
RedirectResponse
{
$student = Student::find($id);
$input = $request->all();
$student->update($input);
return redirect('student')->with('flash_message',
'student Updated!');
}
public function destroy(string $id): RedirectResponse
{
Student::destroy($id);
return redirect('student')->with('flash_message',
'Student deleted!');

}
8. CREATE A MODEL

class Student extends Model
{
protected $table = 'students';
protected $primaryKey = 'id';
protected $fillable = ['name', 'address', 'mobile'];
use HasFactory;
}
9. CREATE VIEWS (Creating Pages)
⮚ Inside views create a new folder named students, then inside the folder, create the following
pages:
● COPY THE FOLLOWING CODES AND PASTE IT TO THEIR RESPECTIVE FILENAMES:

10. ROUTES
●
Pages are Manage through routes.
●
You have to add the ControllerNameSpace.
●
use App\Http\Controllers\StudentController;
⮚ EDIT routes>web.php file
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\StudentController;
Route::get('/', function () {
return view('welcome');
});
Route::resource("/student", StudentController::class);
11. RUN THE PROJECT
php artisan serve
The application should be able to Add New Student, View, Edit
and Delete the data in the database.
