[SOLVED] Values for up and downquantity (in cart...) based on the min QTY for each click!

[AndreasAnemyr]

I use 1.4.0.17

 

Problem:

 

When the user clicks on upQuantity or the downQuantity

the used value should be based on the minal Qty (you can set this value in general info or on the combinations if used...

 

Example

Min qty = 3pcs

When you click Up, it counts up 3,6,9,12 .....

 

Not 3,4,5,6...

 

order-opc.php

 

Would be great if somene have a great solution for this (

maybe in the js cart_summary.

 

Best regards!

And solution is.... ( I use prestashop 1.4.0.17)

 

yourtheme/shopping-cart-product-line.tpl:

Change the inputfield to readonly="readonly".

Customer would not be able to change it to custom value

 

Put a new hidden field in yourtheme/shopping-cart-product-line.tpl

<input id="min_{$product.id}_{$productAttributeId}" type="hidden" value"$product.minimal.quantity"

 

With Jquery you can use this new hidden field to change the "default" qty.

for eht functions downQuantity( ) & upQuantity( )

This is done in the cart-summary.js

 

This is the simple code how it´s made...

qty = $('#min_'+ productID+'_'+productAttributeId).val( );

 

 

Do you need more information. Reply here and i will explain more in details....

Hi

 

I did the same as you said but the default quantity in the cart_summary.js still is 1. It cannot change to the quantity from the input in the shopping-cart-product-line.tpl ---- presta 1.5.4 ---

for prestashop 1.5.4

add this line in yourtheme/shopping-cart-product-line.tpl

 

<input id="min_{$product.id_product}_{$product.id_product_attribute}" type="hidden" value="{$product.minimal_quantity}"/>

 

add this line in cart_summary.js

var qty=$('#min_'+ productId+'_'+productAttributeId).val();

 

line 432 for upQuantity( )

line 513 for downQuantity( )
