Product > Quantity: 0 - category / by default

Hi guys,
we can enable the Catalogue by setting "Configuration > Features > Catalogue mode: Yes" for the entire site.
But, also we can leave it as "No" and choose to enable the Catalogue mode by setting "Product > Quantity: 0" for each products we want. Now:

1 - Is there a way to enable the Catalogue mode by Category (for all the Products included into a specific Category) ?

2 - From a HikaMarket Multi Vendor point of view, as Super User we can always display:none; / pointer-events: none; fields to limit HikaShop features(depending on Vendors User Groups levels), but not the reverse. So, by default it would be better to have "Product > Quantity: 0" and not unlimited.
Do you agree ?

line 1772 - $product->product_quantity = $config->get('default_stock_for_new_products', -1); >>> 0

Hi Nicolas,

2 - hidden option
PHPMyAdmin > hikashop_config table > namekey: default_stock_for_new_products - value 0
It works perfectly, many thanks !
Please, Is there any documentation where can I read more about HikaShop hidden options and HikaShop namekeys ?
(I'm not able to find nothing)

1 - You could do it with a few custom fields and mass actions:
- a custom "category" field with two values "yes" and "no" and the name "catalogue_mode".
- a custom "product" field with the name "saved_quantity".
- a mass action with a trigger "after a category is updated", a filter on the column "catalogue_mode" equal to "yes", and an action "run MySQL query" with the MySQL query: ...
- a mass action with a trigger "after a category is updated", a filter on the column "catalogue_mode" equal to "no", and an action "run MySQL query" with the MySQL query: ...

1A - a custom "product" field with the name "saved_quantity":
Due to "point 2" above, we are working with "product_quantity = 0" by default.
Please, Why it is necessary the creation of the "saved_quantity" custom field and it is not possible to write "0" directly into the "product_quantity" field ?

1B - "Updated" includes also "Created" (the first time a new Category is created) ?

1C - And, as far as I understand, the same also for Products:
- a mass action with a trigger after a product is updated" (and created), when the product is added to a categorie with "catalogue_mode" = "Yes", then the "product_quantity = 0"
- a mass action with a trigger after a product is updated" (and created), when the product is added to a categorie with "catalogue_mode" = "No", if the "product_quantity = 0" (inherit from coming from a Category catalogue mode=Yes), then the "product_quantity = -1" (I suppose "unlimited" is better then "1")
Do you agree ?

Hi Nicolas,
thanks!

1A - Very Good

1B - You are right

1C - Got it, it makes sense

2 - Okay

Question to Nicolas,

2. This is a hidden option. You don't need to change the code for that. Go in your PHPMyAdmin, add a new entry to the hikashop_config table with the namekey default_stock_for_new_products and the value 0 and it will do it. And no worries with updates. The hidden option was made specifically for such cases.

Thanks, Nicolas.

Ik had to go over every category to set whether or not is was a catalog view. But then it worked like a charm.
