STEP 1. View blades

We need following blades for company master

                   1) index.blade.php

                  2) create.blade.php

                  3) edit.blade.php

                  4) show.blade.php

                  

So let's just create following file and put bellow code.

1. resources/views/company/index.blade.php

                  @extends('layout')

                  @section('content')

                  <h2>Companies</h3>
                  <a href="">List All</a>   <a href="">Create New</a>

                            <th>Details</th>
                            <th width="280px">Action</th>
                        </tr>
                       
                        <tr>
                           
                            <td> Company !</td>
                            <td> Cochin</td>

                  @endsection

                

STEP 2. Controller

We should create new controller as CompanyController to show the above blades

Normally a controller should have 7 methods as bellow methods:

1)index()

2)create()

3)store()

4)show()

5)edit()

6)update()

7)destroy()

Let us create above functions and show the blades

app/Http/Controllers/CompanyController.php

  
namespace App\Http\Controllers;
   
   use App\Models\Product;
   use Illuminate\Http\Request;
     
   class ProductController extends Controller
   {
       
       public function index()
       {          
       
           return view('company.index');
       }
        
      
       public function create()
       {

           return view('company.create');
       }
       
    
       public function store(Request $request)
       {
         
        
          
       }        
      
       public function show($id)
       {
        
           return view('company.show');
       } 
        
     
       public function edit(Product $product)
       {

           return view('company.edit');
       }
       
      
       public function update(Request $request, $id)
       {
         

       }
       
     
       public function destroy($id)
       {
          

       }
   }

  

Note that the function name, parameters and return function

STEP 3. Define the routes for above functions

routes/web.php

                    use App\Http\Controllers\CompanyController;


                    Route::get('companies', [CompanyController::class, 'index']);

                    Route::get('companies/create', [CompanyController::class, 'create']);
                    Route::post('companies', [CompanyController::class, 'store']);


                    Route::get('companies/{id}', [CompanyController::class, 'show']);


                    Route::get('companies/{id}/edit', [CompanyController::class, 'edit']);
                    Route::put('companies/{id}', [CompanyController::class, 'update']);


                    Route::delete('companies/{id}', [CompanyController::class, 'destroty']);
                 



                    

STEP 4. Call the routes in the blades

1. to show listing page, use the route url('companies') in 'a href' tag
2. to show create form, use the route url('companies/create') in 'a href' tag

open resources/views/company/index.blade.php and add the url

3. to save the form data, use the route url('companies') in the action of form tag

open resources/views/company/create.blade.php

STEP 5. Table and Model

1. Create table 'companies' with fields id, name and details

2. Create model 'Company.php'

app/Models/Company.php

                namespace App\Models;
  
                use Illuminate\Database\Eloquent\Factories\HasFactory;
                use Illuminate\Database\Eloquent\Model;
                    
                class Company extends Model
                {
                    use HasFactory;
                    
                    protected $fillable = [
                        'name', 'detail'
                    ];
                }

                

STEP 6 . Save data into db

1. Open the controller app/Http/Controllers/CompanyController.php

2. include the Company model in the controller CompanyController.php

3. add the given code inside the function store()

                public function store(Request $request)
                {
                        $company= new Company;
                       
                        $company->name= $request->name;
                        $company->details= $request->details;
                        $company->save();


                }
                

STEP 7 . Get all data to show in the listing page

1. Open the controller app/Http/Controllers/CompanyController.php

2. include the Company model in the controller CompanyController.php

3. add the given code inside the function index()

                public function index(Request $request)
                {
                        $data['company']=Company::get();                       
                        return view('company.index',  $data);

                }
                

STEP 8 . Get the data to show in the view page

1. Open the controller app/Http/Controllers/CompanyController.php

2. include the Company model in the controller CompanyController.php

3. add the given code inside the function show()

                public function show(Request $request, $id)
                {
                        $data['company']=Company::find($id);                       
                        return view('company.show',  $data);

                }
