Purchase Quantity Steps

[jccompagnon]

VM 3.0.2
Joomla 3.3

Hi,

I created a product with a "Purchase Quantity Steps" of 50 but in the product page the buyer is able to click the + and - and select for example 42 then that does add a weird 72 items to cart.

Something is wrong

you can replicate here:

The template does not use any overides

I have the same issue... The steps are not being inforced when you use the arrows (should be +50, -50) in your case but it doesn't work.

[rickkh]

FIXED in VM3.0.2:
1- Open /components/com_virtuemart/assets/js/vmprices.js
2- Locate Virtuemart.product = function(carts) {
3- Replace:
                step=cart.find('input[name="quantity"]'),
WITH:

                step=cart.find('input[name="quantity[]"]'),

thanks.
I however have VM 3.0.2 and it is not fixed in that version.
I made your changes and it fixed it but is not fixed in 3.0.2

thanks for the fix

[Milbo]

I meant, fix for vm3.0.2.

Thanks for the fix, I will directly add it. I will upload soon a vm3.0.3 for further testing.

[rickkh]

Sure. I want to add that despite this fixing the quantity step order level for +/- quantity, users can still use the keyboard to enter quantities that are different from the step order level.
This is not being enforced in VM3.

What I did is have a small javascript function that fires onblur and onchange to automatically change the value back depending on what the user entered. Please reply to this thread so that I can see it as new replies and I'll post the function later tonight.

For those who need to prevent users from entering an amount that is different from the step level /minimum level using the keyboard, please do this:

1- Locate the following code in your category's default.php. If you are using a template, this should be under template/TEMPLATE_NAME/html/category/default.php

Code Select Expand

<span class="quantity-box">
        <input id="test" type="text" class="quantity-input js-recalculate" name="quantity[]" value="<?php if (isset($product->min_order_level) && $product->min_order_level > 0.0) {
            echo $product->min_order_level;
        } else {
            echo '1';
        } ?>"
        />
        </span>


Add the following at the end of the above, BEFORE </span>

Code Select Expand


onblur="<?php echo "checkValue(this, $product->min_order_level)" 
        ?>"
        onchange="<?php echo "checkValue(this, $product->min_order_level)"
        ?>"


2- Add the following javascript function somewhere where it will only be loaded one in the same file (outside any foreach loop)

Code Select Expand

function checkValue(sender, step)
{
                                   var value = parseInt(sender.value);
                                    if (step == '') { step=1; } //if min_order quantity is not specified, make it one
                                    if (value == '' || isNaN(value)) {
                                                  sender.value = step;
                                     } else if (value < step) { sender.value = step; }
                                      else if (value%step != 0 && value > step) {
                                            sender.value = (value - (value%step));
                                     } else {
                                             return sender.value;
                                       }
                      }

It is also not being enforced on the modules like "latest product", .....

[cimran]

FIXED in VM3.0.2:
1- Open /components/com_virtuemart/assets/js/vmprices.js
2- Locate Virtuemart.product = function(carts) {
3- Replace:
                step=cart.find('input[name="quantity"]'),
WITH:

                step=cart.find('input[name="quantity[]"]'),

I'm unable to locate this file; can you please guide

Just use VM3.0.4

Im using VM 2.6.14, and im having similar issue:
Everytime i hit + or - que quantity increase/decrease by 2.
This happens only with products that has stockable variant childs.
You can check here: http://ideaalab.com/shop/radiofrecuencia/mandos
Almost all products in that page has stockable variant childs.

Im guessing that is a conflict of javascript?

YOu have a module or something addding the

Virtuemart.product($("form.product"));

in the html body.

But virtuemart have already this function

Virtuemart.product($("form.product"));

in the virtuemart javascript file :
components/com_virtuemart/assets/js/vmprices.js?vmver=8609
This mean you have 2 clicks,events ...  for all your form and button in form.

the bad function in your code is this

function recalculate_7913(stockableBlockIndex, Opt){

[Marttyn]

I tried to check with firebug, but im not sure how to use the script functionality of it
How did you found out that?
I will try to disable my template override, and every module secuencially until i find the problem

[Studio 42]

It's not a overide problem,
This come from the child variant customfield product plugin.
You have to search for function recalculate_
& remove Virtuemart.product($("form.product")); from here

[Marttyn]

Thanks for your reply!
Are you saying its a VM problem? Or some customization ive made that cause the problem?
