Magento

20 I want to validate in the add to cart quantity when someone enter negative or zero value in the quantity. I know that magento by default take 1 value if someone entry negative or zero value. Anyone have any idea about this one.

There is no one that can solve this problem in magento forum?????????

Maybe too late, but you just have to add a validate-greater-than-zero class to the field. All validation classes are available here: http://www.magentocommerce.com/wiki/5_-_modules_and_development/admin/xml_structure_for_admin_configurations

Hi,
In Product details page we are having the quantity field, by default it accepts strings and negative numbers. we can fix this issue very easily just by adding class names.

app->design->frontend->default-> <your theme> ->template->catalog->product->view->addtocart.phtml
in line 33 you can see the text filed with id="qty", just add the following classes for that field
validate-greater-than-zero validate-number

You can see all the validation classes in
