it would be nice to add a function that checks product quantity when adding product to cart... opencart 1.5.1.3 does not have this function... you can easily add ie.100 units of a product into cart regardless of product availibility in stock... to be specific: there's 5 units of a product in stock but it doesn't prevetn user to insert greater value than that in quantity field on product page... i think you see my point here...

The validation is done at the checkout step instead. If you have allow checkout set to NO.. it will not allow you to purchase 100 of an item you only have 5 of

i know that,but wouldn't it be better to have a function that validates that on product's page? i think it would... because a customer always likes a good usability... do you agree with me?

(1.5.x)
1. EDIT: catalog/controller/checkout/cart.php
2. FIND:
Code: Select all
if ($product_info['minimum'] > ($product_total + $quantity)) {
3. BEFORE, ADD:
Code: Select all
if ($product_info['quantity'] < $quantity) {
$json['error']['warning'] = sprintf($this->language->get('error_understock'), $product_info['quantity']);
}
4. EDIT: catalog/language/english/checkout/cart.php
5. FIND:
Code: Select all
$_['error_minimum'] = 'Minimum order amount for %s is %s!';
6. AFTER, ADD:
Code: Select all
$_['error_understock'] = 'Requested quantity greater than stock quantity: %s!';

Hi ,
Just realised that I had a problem with this code. When I have options in products, I need to check for the quantity from the options.
How do I modify the code to check the quantity from options when I have at least one option for a product.
Tried few variations, based on my measly knowledge of OC and php...but nothing is working.
Please help.
Regards,
FM

This is exactly what I am looking for, however, the code above does not work for me.
in catalog/controller/checkout/cart.php
I do not have the line:
if ($product_info['minimum'] > ($product_total + $quantity)) {
instead, I have:
if ($product['minimum'] > $product_total) {
when I place the edited code above by Qphoria, nothing happens. I'm sure it is just a simple fix and I just need to change a couple of words. If anyone could help, that would be great.
Thanks

Hi Guys,
anybody found a workaround for 1.5.4.1 for this? Would greatly appreciate it.

Can someone please help me to add an alert message on the product page.
If the product quantity entered is 0, an error message "Quantity entered is 0, no products have been added to the cart!"
At the moment, when the product quantity is 0, nothing is added to the cart but there is no notification.
Thank you for you any assistance.
(OC v1.5.5.1)

Hi,
I also tried to use the code but i guess that is not working with OC v1.5.5.1 . If anyone has found the solution and can share here would be much helpful.
Thanks in advance.
Andy

I have already dealt with this by way of a new extension that builds on top of my max quantity one.
Currently, the new extension deals with preventing adding to cart of too few products, too many products or more products than are in stock by way of the following:
- - Minimum order quantity validation / warning message on product page and cart;
- Maximum order quantity validation / warning message on product page and cart;
- Stock quantity validation / warning message on product page;
- Options Stock validation / warning message (displays warning for option with lowest available stock) on product page;
Example warnings shown below.
Not released yet, still testing and tweaking but should be ready this week sometime.

It's nearly done, some more testing to do yet but very close.
I have it working at the moment on a test site, have a play with the following products:
