Adding $product.minimal_quantity to quantity field by Up or Down button

[RiesjardVV]

Dear Prestashop developers,

 

Moving over to PS 1.7 i have one requirement to implement in my new 1.7 implementation.

 

The wanted quantity is default set with value $product.minimal_quantity

 

I need to add/substract $product.minimal_quantity to wanted quantity field in product page by Up or Down button next to input field.

 

I already made the input field disabled so values can only be changed by Up or Down button.

 

We had this working in 1.6 by doing some Javascript adjustments, since architecture in 1.7 is totally different I can not find the place where to do changes in 1.7.

 

Hope someone has solution for my issue.

 

Grtz Richard
