BO - change default product quantity

[Byte Webdesign]

Hello!

Is it possible to change the default product quantity when adding a new product?
My client buys most products in bulk so it would save alot of time. 
The shop is using PS: 1.6.1.13
Thanks in advance!
Regards,
Frank

Your link doesn't work. I get a "you don't have permission for this" error.

Was a link to another post on this forum: https://www.prestashop.com/forums/topic/518476-default-quantity-1-when-adding-new-product/
I tried that solution but it doesn't work for me, some help would be appreciated!

I haven't tested it but I think that something like the following should work:

 

In the add() function in Product.php near the end you have the following code:

foreach ($id_shop_list as $value)
	StockAvailable::setProductOutOfStock((int)$this->id, 2, $value);

That should become something like

foreach ($id_shop_list as $value) {
	StockAvailable::setProductOutOfStock((int)$this->id, 2, $value);
        StockAvailable::updateQuantity((int)$this->id, 0, $quantity, $value);
}

Note that the zero stands for id_product_attribute. If your products have attributes you will need to do something with that.

Hello Musicmaster,
First of all thanks for the quick reply!  

I have added the mentioned code but sadly it still adds new product with a quantity of 0

 

 

public function add($autodate = true, $null_values = false)

{
if (!parent::add($autodate, $null_values)) {
return false;
}

$id_shop_list = Shop::getContextListShopID();
if ($this->getType() == Product::PTYPE_VIRTUAL) {
foreach ($id_shop_list as $value) {
StockAvailable::setProductOutOfStock((int)$this->id, 1, $value);
}

if ($this->active && !Configuration::get('PS_VIRTUAL_PROD_FEATURE_ACTIVE')) {
Configuration::updateGlobalValue('PS_VIRTUAL_PROD_FEATURE_ACTIVE', '1');
}
} else {
foreach ($id_shop_list as $value) {
StockAvailable::setProductOutOfStock((int)$this->id, 2, $value);
StockAvailable::updateQuantity((int)$this->id, 0, $quantity, $value);
}
}

$this->setGroupReduction();
Hook::exec('actionProductSave', array('id_product' => (int)$this->id, 'product' => $this));
return true;
}

And where did you add your quantity? It was meant that you replaced "$quantity"  with your number.

 

BTW: do you have development mode enabled? You should have gotten an error message for an undefined variable.

I do have dev mode enabled indeed and didn't get an error message.
I tried to define $quantity and did get an error message then. 

But just changing $quantity with a number did the trick! Problem solved, thanks Musicmaster

I am glad you solved this. 

 

Note that a missing value is a warning, not an error. So it generates a message but then the rest of the page will be generated. At most you will see that the header of your webpage is a bit misformed. However, if you select to see the page source in your browser you will see the message (search for words like error and warning).
