decrementing existence of product

[ngomezleal]

Hi all, 

 

Could you please tell me where this prestashop php in the file, which makes the reduction of a product when a purchase is made using the method of payment by check? 

 

waiting for your valuable responses.

You mean which snippet is responsible of decreasing product quantities?

OrderHistory.php

OrderHistory::changeIdOrderState()

 

Look for StockAvailable::updateQuantity($product['product_id'], $product['product_attribute_id'], -(int)$product['product_quantity'], $order->id_shop);

 

And other occurrences of that method

Nemo1 Hi thank you very much for your answer. 

 

Nemo1, just let me know the resposable of declining product by any method. 

 

Nemo1, based on your answer, I found the file in: 

classes / order / => OrderHistory.php 

 

Nemo1 would do the following: 

 

Instead of reducing the product, the product increases. 

The code to which you refer is me: 

 

StockAvailable :: updateQuantity ($ product ['product_id'], $ product ['product_attribute_id'], - (int) $ product ['product_quantity'], $ Order-> id_shop); 

 

I note that this - (int) $ product ['product_quantity'] 

Changing it to + (int) $ product ['product_quantity'] 

 

It can run?

[NemoPS]

It should increment instead of decrementing (again, I didn't test it)

[ngomezleal]

Very good Nemo1 thanks for your answer.

 

Nemo1, In prestashop there is an option to cancel or accept orders placed by buyers, specifically php level, where I can find the code where the user (administrator) cancels the purchase they have made?

 

I hope you understand me

[NemoPS]

You mean setting an order status to canceled?

[ngomezleal]

Exactly 

 

I mean, when a customer makes a purchase, the administrator has the option of:

 

* cancel 

* approve 

* among others ... 

 

If for example the customer bought an article available there 20, when it is performed in the 19. 

 

When the administrator cancel the purchase, return again to 20. 

 

I wonder php code level, where it performs that action, that is, that php file I find that? 

 

Muchs thanks for your valuable answers Nemo1. They have been of great benefit.

[NemoPS]

It should be the same one I mentioned before actually, as it creates a new order state

 

($old_os->id == Configuration::get('PS_OS_ERROR') || $old_os->id == Configuration::get('PS_OS_CANCELED')) &&

!StockAvailable::dependsOnStock($product['id_product'], (int)$order->id_shop))

StockAvailable::updateQuantity($product['product_id'], $product['product_attribute_id'], -(int)$product['product_quantity'], $order->id_shop);

Hi Nemo1, thanks so much for your answers.

 

 

This code works when you have your prestashop site but the option of multi-shop.

 

1.- ***********************************

 

OrderDetail.php

 

** Original State

 

if (!StockAvailable::dependsOnStock($product['id_product']))

$update_quantity = StockAvailable::updateQuantity($product['id_product'], $product['id_product_attribute'], -(int)$product['cart_quantity']);

 

** Changed State.

 

/**

 * Check the order status

 * @param array $product

 * @param int $id_order_state

 */

protected function checkProductStock($product, $id_order_state)

{

if ($id_order_state != Configuration::get('PS_OS_CANCELED') && $id_order_state != Configuration::get('PS_OS_ERROR'))

{

$update_quantity = true;

if (!StockAvailable::dependsOnStock($product['id_product']))

$update_quantity = StockAvailable::updateQuantity($product['id_product'], $product['id_product_attribute'], +(int)$product['cart_quantity']);

 

if ($update_quantity)

$product['stock_quantity'] -= $product['cart_quantity'];

 

if ($product['stock_quantity'] < 0 && Configuration::get('PS_STOCK_MANAGEMENT'))

$this->outOfStock = true;

Product::updateDefaultAttribute($product['id_product']);

}

}

 

2.- *********************************** State Error/Canceled.

 

OrderHistory.php

 

** Original State:

 

StockAvailable::updateQuantity($product['product_id'], $product['product_attribute_id'], (int)$product['product_quantity'], $order->id_shop);

 

** Changed State.

 

// if waiting for payment => payment error/canceled elseif (!$new_os->logable && !$old_os->logable && in_array($new_os->id, $errorOrCanceledStatuses) && !in_array($old_os->id, $errorOrCanceledStatuses) && !StockAvailable::dependsOnStock($product['id_product'])) StockAvailable::updateQuantity($product['product_id'], $product['product_attribute_id'], -(int)$product['product_quantity'], $order->id_shop);

 

 

 

**********************************************************

 

With this code (adapted to my needs), do the following: 

 

1.-When an order is being performed, rather than decrease existence, increases. 

 

2.-When you want to cancel an order, rather than increasing, decreases.

Nemo1, the code written above, does not work when I have the option of department stores. 

 

Where is the code to decrease when the product option multistore and advanced stock used ???

[ngomezleal]

Hi Nemo1,

 

You can guide me please, where is php code level to decrease when the product option and stock multistorey used advanced ??? 

 

That is, where the product remains when an order is made.
