Overview

Step 1: Create Routes
Step 2: Create a Model and Controller
Step 3: Create Blade Files
Step 4: Run Our Laravel Application

Step 1: Create Routes
Add the following route code in the “routes/web.php” file.

use App\Http\Controllers\StudentController;

Route::get('student',[StudentController::class, 'create']);
Route::post('student',[StudentController::class, 'store']);

use App\Http\Controllers\StudentController;

Route::get('student',[StudentController::class, 'create']);

Route::post('student',[StudentController::class, 'store']);

Step 2: Create a Model and Controller
Here below command help to create the controller and model.

php artisan make:controller StudentController --resource --model=Student

1	php artisan make:controller StudentController --resource --model=Student

Student.php

<?php

namespace App/Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;



class Student extends Model
{
    use HasFactory;
    protected $fillable = [
        'first_name','last_name', 'address'
    ];
}

?>

<?php

namespace App/Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Student extends Model

{

use HasFactory;

protected $fillable = [

'first_name','last_name', 'address'

];

}

StudentController.php

<?php

namespace App\Http\Controllers;

use App\Models\Student;
use Illuminate\Http\Request;

class StudentController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //
        $students = Student::all();
        return view('student.list', compact('students','students'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
        return view('student.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
        $request->validate([
            'txtFirstName'=>'required',
            'txtLastName'=> 'required',
            'txtAddress' => 'required'
        ], [
                'txtFirstName.required' => 'FirstName is required',
                'txtLastName.required' => 'LastName is required',
                'txtAddress.required' => 'Address is required'
            ]);

        $student = new Student([
            'first_name' => $request->get('txtFirstName'),
            'last_name'=> $request->get('txtLastName'),
            'address'=> $request->get('txtAddress')
        ]);

        $student->save();
        return redirect('/student')->with('success', 'Student has been added');
    }
}
?>

<?php

namespace App\Http\Controllers;

use App\Models\Student;

use Illuminate\Http\Request;

class StudentController extends Controller

{

/**

* Display a listing of the resource.

* @return \Illuminate\Http\Response

public function index()

{

$students = Student::all();

return view('student.list', compact('students','students'));

}

/**

* Show the form for creating a new resource.

* @return \Illuminate\Http\Response

public function create()

{

return view('student.create');

}

/**

* Store a newly created resource in storage.

* @param \Illuminate\Http\Request $request

* @return \Illuminate\Http\Response

public function store(Request $request)

{

$request->validate([

'txtFirstName'=>'required',

'txtLastName'=> 'required',

'txtAddress' => 'required'

], [

'txtFirstName.required' => 'FirstName is required',

'txtLastName.required' => 'LastName is required',

'txtAddress.required' => 'Address is required'

]);

$student = new Student([

'first_name' => $request->get('txtFirstName'),

'last_name'=> $request->get('txtLastName'),

'address'=> $request->get('txtAddress')

]);

$student->save();

return redirect('/student')->with('success', 'Student has been added');

}

Step 3: Create Blade Files
So finally, first we will create the new directory “resources/views/student/layouts” and that directory in creating a “resources/views/student/layouts/app.blade.php” file. and the second time we will create a list.blade.php in the “resources/ views/student/” directory.
layout.blade.php

Step 4: Run Our Laravel Application
We can start the server and run this example using the below command.

php artisan serve

1	php artisan serve

Now we will run our example using the below Url in the browser.

http://127.0.0.1:8000/student

1	http://127.0.0.1:8000/student
