Create Read Update And Delete CRUD Operation in Laravel 7

In this tutorial, I show you how to select, install, update, and delete a record from a MySQL database with Laravel 7.

Create a new table subjects using migration.

php artisan make:migration create_subjects_table

Now, navigate to database/migration/ directory from the project root.
Find a PHP file which ends with create_subjects_table and open it.
Define the table structure in the up() method.

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

Run the migration –

php artisan migrate

Create Subjects Model.

<?php

namespace App;
use IlluminateDatabaseEloquentModel;
class Subjects extends Model
{
   protected $fillable = [
      'name','description' 
   ];
}
?>

Open routes/web.php file.

## View 
Route::get('/subjects', 'SubjectsController@index')->name('subjects');

## Create
Route::get('/subjects/create', 'SubjectsController@create')->name('subjects.create');
Route::post('/subjects/store', 'SubjectsController@store')->name('subjects.store');

## Update
Route::get('/subjects/store/{id}', 'SubjectsController@edit')->name('subjects.edit');
Route::post('/subjects/update/{id}', 'SubjectsController@update')->name('subjects.update');

## Delete
Route::get('/subjects/delete/{id}', 'SubjectsController@destroy')->name('subjects.delete');

Create SubjectsController Controller.

php artisan make:controller SubjectsController

Open app/Http/Controllers/SubjectsController.php

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;

use IlluminateSupportFacadesSession;
use IlluminateSupportFacadesValidator;

use AppSubjects;

class SubjectsController extends Controller {

   public function index(){
      $subjects = Subjects::select('id','name','description')->get();
      return view('subjects.index')->with('subjects',$subjects);
   }

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

   public function store(Request $request){
      $data = $request->except('_method','_token','submit');

      $validator = Validator::make($request->all(), [
         'name' => 'required|string|min:3',
         'description' => 'required|string|min:3',
      ]);

      if ($validator->fails()) {
         return redirect()->Back()->withInput()->withErrors($validator);
      }

      if($record = Subjects::firstOrCreate($data)){
         Session::flash('message', 'Added Successfully!');
         Session::flash('alert-class', 'alert-success');
         return redirect()->route('subjects');
      }else{
         Session::flash('message', 'Data not saved!');
         Session::flash('alert-class', 'alert-danger');
      }

      return Back();
   }

   public function edit($id){
      $subject = Subjects::find($id);

      return view('subjects.edit')->with('subject',$subject);
   }

   public function update(Request $request,$id){
      $data = $request->except('_method','_token','submit');

      $validator = Validator::make($request->all(), [
         'name' => 'required|string|min:3',
         'description' => 'required|string|min:3',
      ]);

      if ($validator->fails()) {
         return redirect()->Back()->withInput()->withErrors($validator);
      }
      $subject = Subjects::find($id);

      if($subject->update($data)){

         Session::flash('message', 'Update successfully!');
         Session::flash('alert-class', 'alert-success');
         return redirect()->route('subjects');
      }else{
         Session::flash('message', 'Data not updated!');
         Session::flash('alert-class', 'alert-danger');
      }

      return Back()->withInput();
   }

   // Delete
   public function destroy($id){
      Subjects::destroy($id);

      Session::flash('message', 'Delete successfully!');
      Session::flash('alert-class', 'alert-success');
      return redirect()->route('subjects');
   }
}
?>

Create a layout and subjects folder at resources/views/.

Create the following files in the folders –

layout

app.blade.php

subject

index.blade.php
create.blade.php
edit.blade.php

layout/app.blade.php
