Conclusion

Step 1 : Download Laravel

After installing composer in your environment just run below command to download laravel.

composer create-project --prefer-dist laravel/laravel blog

Step 2: Connect Database

In this we have to connect database. Cause without database we can't save our data. So connect it like below.

.env


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

Step 3: Create Model and Migration

Now we need to create our model and migration to get table to create laravel 7 crud app. run below command to create model and migration file.

php artisan make:model Contact -m

database/migrations/create_contacts_table.php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateContactsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('contacts', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamps();
        });
    }

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

Now run this below command to migrate this table.

php artisan migrate

Now open contact model and paste this below code.

app/Contact.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Contact extends Model
{
    protected $guarded = [];
}

Step 4: Create Routes

Now time to create our routes to make laravel crud. Now open "routes/web.php" and paste below code.

routes/web.php

Route::get('user', 'UserController@index')->name('user.index');;
Route::get('user/create', 'UserController@create')->name('user.create');
Route::post('user/store', 'UserController@store')->name('user.store');
Route::get('user/edit/{id}', 'UserController@edit')->name('user.edit');
Route::patch('user/update/{id}', 'UserController@update')->name('user.update');
Route::delete('user/delete/{id}', 'UserController@destroy')->name('user.destroy');

Step 5: Create Controller

In this step we need to create our UserController to create all the method. So run below command to create UserController

php artisan make:controller UserController

now open UserController and paste this below code in it.

app/Http/Controllers/UserController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests\UserRequest;

class UserController extends Controller
{
    public function index()
    {
       if(\View::exists('user.index')){
           $user = \App\Contact::latest()->get();
           return view('user.index',compact('user'));
       }
    }

    public function create()
    {
        if(\View::exists('user.index')){
            return view('user.create');
        }
    }

    public function store(UserRequest $request)
    {
        \App\Contact::create($request->all());
        $this->message('message','User created successfully');
        return redirect()->back();
    }

    public function edit($id)
    {
        if(\View::exists('user.edit')){
            $user = \App\Contact::findOrFail($id);
            return view('user.edit',compact('user'));
        }
    }

    public function update(UserRequest $request, $id)
    {
        $user = \App\Contact::findOrFail($id);
        $user->name = $request->name;
        $user->email = $request->email;
        $user->save();
        $this->message('message','User updated successfully');
        return redirect()->route('user.index');
    }

    public function destroy($id)
    {
        $user = \App\Contact::findOrFail($id);
        $user->delete();
        $this->message('message','User deleted successfully');
        return redirect()->back();
    }

    public function message(string $name = null, string $message = null)
    {
        return session()->flash($name,$message);
    }
}

Step 6: Create Blade File

We are in the final step to complete this laravel 7 crud tutorial example. Just we need to create some blade file to see our data and html form to submit data.

resources/views/layouts/app.blade.php

resources/views/user/create.blade.php

resources/views/user/edit.blade.php

resources/views/user/index.blade.php

resources/views/user/message.blade.php

Now you can open bellow URL on your browser:

http://localhost:8000/user
