Minimum quantity

[zhihsam]

Hello!

 

I need to add to products minimum quantity BUT for example if minimum quantity is equal to 50, users shouldn't be allowed to buy 51 product, they should be able to buy only 50, 100, 150 etc.

 

And it's should be made without using product pack.

 

Thank you.

Same problem on our shop - did you find the solution meanwhile? If so, how did you solve it? Thank you for your help!

In the root_folder/themes/mytheme/product.tpl i added data attribute to quantity input:

 

<input type="text" data-quantity="{$product->minimal_quantity}" name="qty" id="quantity_wanted" class="text" value="1" size="2" maxlength="4">

 

data-quantity="{$product.minimal_quantity}" is what you actualy need.

 

When users click on "add to cart" button they invoke function in root_folder/themes/mytheme/js/modules/blockcart/ajax-cart.js file (if not exists you should copy original file from root_folder/modules/blockcart/ajax-cart.js to path given above).

Function is called overrideButtonsInThePage. I made some changes to parse data-quantity from input for multiplying it to minimal quantity

i.e.

....

overrideButtonsInThePage : function(){

    ...

    //for product page 'add' button...

    $('#add_to_cart input').unbind('click').click(function(){

      var input = $('#quantity_wanted'),                                                  // input

          quantity = input.val() * input.data('quantity');                              // parsing our quantity from data-attribute and multiplying by it

      ajaxCart.add( $('#product_page_product_id').val(), $('#idCombination').val(), true, null, quantity, null);

      return false;

    })

    ...

 

Also you shoudn't forget to add similar code changes (i mean to add data-quantity attribute) to other parts of your shop (shopping-cart page, order page e.t.c)

 

After all changes done, when you set minimal quantity to your product (e.g. 50) users will be able to buy only 50 or 100 or 150 as it was needed.
