Adding product data - crud of products

Step 01: Adding product add button just above of table element in list of products

<h2 class="float-start">All Products</h2>
<div class="float-end">
	<a class="btn btn-sm btn-primary" href="{{ route('products.create') }}"> Add Product</a>
</div>  

Step 02: In ProductController, adding create() method

public function create( ) {
	$meta_title = 'Add Product';
	return view( 'products.create', compact( 'meta_title' ) );
} 

Step 03: Adding create.blade.php under resources/view/products folder and putting following snippet inside blade section directive extending app layout

<div class="container">
<div class="row justify-content-center">
    <div class="col-md-8">
    <h2 class="float-start">Add Product</h2>
    <div class="float-end">
        <a class="btn btn-sm btn-primary" href="{{ route('products.index') }}"> Back to products</a>
    </div>
    <div class="clearfix"></div>
    <div class="card ">
        <div class="card-body">
        <form method="post" action="{{ route('products.store') }}" id="updatefrm" method="post"> @csrf <div class="form-group mb-2">
            <label for="title">Name</label>
            <br>
            <input name="name" class="form-control" placeholder="product name" title="Product Name" type="text" id="ProductName" value="{{ old('name') }}" /> 
            @if ($errors->has('name')) 
                <span class="text-danger">{{ $errors->first('name') }}</span> 
            @endif
            </div>
            <div class="form-group mb-2">
            <label for="title">Cost ($)</label>
            <br>
            <input name="cost" class="form-control" placeholder="Cost" title="Cost" type="text" id="cost" value="{{ old('cost') }}" /> 
            @if ($errors->has('email')) 
                <span class="text-danger">{{ $errors->first('email') }}</span> 
            @endif
            </div>
            <input class="btn btn-sm btn-primary" class="form-control" type="submit" name="action" value="Add">
        </form>
        </div>
    </div>
    </div>
</div>
</div>
</div> 

Step 04: Creating ProductRequest.php using artisan command for validation of form fields

php artisan make:request ProductRequest

Step 05: Adding validation rules like below in ProductRequest.php making sure authorize function returns true

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class ProductRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [                         
            'name' => 'required',             
            'cost' => 'required',                  
        ];
    }
}

Step 06: Changing Product.php model like below adding fillable with saving fields and mutator for saving slug with name

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

class Product extends Model
{
    use HasFactory;

    protected $fillable = [
        'name', 'user_id', 'description', 'slug', 'cost', 'status', 'sequence'
    ]; 
    
    function setNameAttribute($value) { 
        $this->attributes['name'] = $value; 
        $this->attributes['slug'] = Str::slug($value); 
    }

}

Step 07: Back in ProductController adding store() method like below and redirecting to products list page after addition

//at the top 
use App\Http\Requests\ProductRequest;
use App\Models\Product;

public function store( ProductRequest $request ) {
	Product::create([
		'name' => $request->name,
		'user_id' => auth()->user()->id,
		'description' => $request->description ?? '',
		'cost' => $request->cost,
		'status' => !empty($request->status) ? 1 : 0,
		'sequence' => ( Product::latest('sequence')->first()->id + 1 ) // fetching last sequence value from products table and adding one to it
	]);     
	
	return redirect()->route('products.index');
}

Now if we fillup the create form and submit it, product information with all its fields will be saved to products table in the database.
