Coupons

[ghost]

Hello!

how I can use Coupons with your package ?

[amostajo]

The coupons feature is in development.

[ghost]

Can say a date for publish it in develop ?

I'm looking for this improvement too. Any ideas when it will be ready? Meanwhile, any tips on how can I implement this myself? Thanks!

Depending how complex will your coupons be.

Locally the next push to dev will have:

Coupons with specific amount. Coupons with specific percentage discount. Coupons that only apply to certain SKUs. Coupons with expiration date. Coupons with usage limit. Coupons that only apply to certain users. On Dec 2, 2015 10:38 AM, "mbl-at" notifications@github.com wrote:

Create a new migration: php artisan make:migration add_coupon_functionality

Add the following to the migration:

public function up()
    {
        Schema::create('coupon_links', function (Blueprint $table)
        {
            $table->integer('coupon_id');
            $table->integer('coupon_link_id');
            $table->string('coupon_link_type');
        });
    }

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

In your Coupon Model:

    /**
     * Get all of the orders that are assigned this coupon.
     */
    public function orders()
    {
        return $this->morphedByMany(Config::get('shop.order'), 'coupon_link');
    }

    /**
     * Get all of the carts that are assigned this coupon.
     */
    public function carts()
    {
        return $this->morphedByMany(Config::get('shop.cart'), 'coupon_link');
    }

In your Order Model:

    /**
     * Get all of the coupons for the order.
     */
    public function coupons()
    {
        return $this->morphToMany(Config::get('shop.coupon'), 'coupon_link');
    }

In your Cart Model:

    /**
     * Get all of the coupons for the cart.
     */
    public function coupons()
    {
        return $this->morphToMany(Config::get('shop.coupon'), 'coupon_link');
    }

In ShopCalculationsTrait.php:

Add our getter @ line 86:

    public function getTotalDiscountAttribute()
    {
        if (empty($this->shopCalculations)) $this->runCalculations();

        return round($this->shopCalculations->totalDiscount, 2);
    }

Add our display getter @ line 137:

    public function getDisplayTotalDiscountAttribute()
    {
        return Shop::format($this->totalDiscount);
    }

Adjust the cart/order calculations @ line 189:

//Add total discount, edit totalPrice
        $PivotOn = $this->table == Config::get('shop . order_table') ? 'App\Order' : 'App\Cart';
        $Discounts = $this->calculateDiscounts($PivotOn, $this->attributes['id']);

        //Remove Cash Discount
        $this->shopCalculations->totalPrice -= $Discounts['cash'];

        //Remove % Discount
        $PercentageDiscount = $this->shopCalculations->totalPrice;
        $this->shopCalculations->totalPrice -= $this->shopCalculations->totalPrice * $Discounts['percent'];
        $PercentageDiscount -= $this->shopCalculations->totalPrice;

        $this->shopCalculations->CashDiscount = $Discounts['cash'];
        $this->shopCalculations->PercentDiscount = $Discounts['percent'];
        $this->shopCalculations->PercentCashDiscount = $PercentageDiscount;
        $this->shopCalculations->totalDiscount = $Discounts['cash'] + $PercentageDiscount;

Add additional function at the bottom:

    /**
     * Calculates the discount required on a class with a specified id
     * @param $PivotOn
     * @param $id
     * @return array
     */
    private function calculateDiscounts($PivotOn, $id)
    {
        $Class = new $PivotOn;
        $Coupons = $Class::find($id)->coupons;

        $Discount = [
            'cash'    => 0.00,
            'percent' => 0.00,
        ];
        foreach ($Coupons as $coupon)
        {
            if (!is_null($coupon->value))
                $Discount['cash'] += $coupon->value;
            else
                $Discount['percent'] += $coupon->discount;
        }

        return $Discount;
    }

When Using a flat cash discount (specified by value) you will see:

{#812
     +"totalPrice": 51.98,
     +"totalTax": "0.00",
     +"totalShipping": "3.00",
     +"CashDiscount": 20.0,
     +"PercentDiscount": 0.0,
     +"PercentCashDiscount": 0.0,
     +"totalDiscount": 20.0,
   }

When Using a percentage discount on the basket you will see:

{#812
     +"totalPrice": 64.782,
     +"totalTax": "0.00",
     +"totalShipping": "3.00",
     +"CashDiscount": 0.0,
     +"PercentDiscount": 0.1,
     +"PercentCashDiscount": 7.198,
     +"totalDiscount": 7.198,
   }
