Validate Menu Item Stock Qty & Cart Item Qty while adding to cart

yoursantu

Hi,
I want to validate the Cart item quantity should equal or less than Menu item stock quantity while adding items to cart.
Currently it is validated when Checkout button is clicked. but i want to validate while adding items to the cart.

Please help.

Thank you.

Use this as a starting point:
https://github.com/ryanmitchell/ti-ext-choosetime

You could get the data you need from $cartItem, or if not there Menus_model::find($cartItem->id).

Dear Ryan,
Thank you very much for the great hint.
and i have created custom extension to validate $cartItem->qty.
in boot() method

Event::listen('cart.adding', function($cartItem){
            $cartItem = Cart::content()->each(function($cartItem) {
                if ($menuItem = Menus_model::find($cartItem->id)) {

                   if($cartItem->qty >= $menuItem->stock_qty)
                   throw new ApplicationException(sprintf(
                    lang('igniter.cart::default.alert_low_on_stock'),
                    $menuItem->menu_name,
                    $menuItem->stock_qty
                ));
                }
            });
            return [$cartItem];

But having issue, once the exception throw, the same continued on whole cart items, this is not allowing to add any items, till remove or update quantity in cart

I don’t think you should be looping over the cart items but rather validating the cart item that is being added. It should simplify your code down a lot (the loop isn’t needed)

ryanmitchell
Yeah, but i had checked without looping the $cartItem

Event::listen('cart.adding', function($cartItem) {
    if ($menuItem = Menus_model::find($cartItem->id)) {
                if($cartItem->qty >= $menuItem->stock_qty)
                   throw new ApplicationException(sprintf(
                    lang('igniter.cart::default.alert_low_on_stock'),
                    $menuItem->menu_name,
                    $menuItem->stock_qty
                ));
            }
});

That throwing exception “Undefined property: Igniter\Flame\Cart\Cart::$id” because the $cartItem does`t contain property id!!
What is the fix for that!?

ryanmitchell

dd($cartItem) to see what is available 🙂

ryanmitchell

You can use $cartItem->getModel() I believe

yoursantu

ryanmitchell
already checked dd($cartItem) there is no any required instance!

$cartItem->getModel()

“Undefined property: Igniter\Flame\Cart\Cart::$getModel()”

And i have checked vendor/tastyigniter/flame/src/Cart/Cart.php
available available method content() to retrieve cart items
but i can`t get id without looping it!! 🙁

ryanmitchell

Event::listen('cart.adding', function($cartItem) {
    if ($menuItem = $cartItem->getModel()) {
                if($cartItem->qty >= $menuItem->stock_qty)
                   throw new ApplicationException(sprintf(
                    lang('igniter.cart::default.alert_low_on_stock'),
                    $menuItem->menu_name,
                    $menuItem->stock_qty
                ));
            }
});

"Call to undefined method Igniter\Flame\Cart\Cart::getModel()"

ryanmitchell

Event::listen('cart.adding', function($cart, $cartItem) {
    if ($menuItem = $cartItem->getModel()) {
                if($cartItem->qty >= $menuItem->stock_qty)
                   throw new ApplicationException(sprintf(
                    lang('igniter.cart::default.alert_low_on_stock'),
                    $menuItem->menu_name,
                    $menuItem->stock_qty
                ));
            }
});
