Quantity limit of each product in one OpenCart order
The extension allows you to limit the maximum amount of each product that can be added to the cart on OpenCart. That is, for each product, you can set your own quantity limit value or you can not set it, then such a product can be bought in unlimited quantities.
Next to the "Minimum quantity" field, the "Maximum quantity" field is added, which will work similarly, but will already set the upper limit of the quantity of goods for one order. So, with the help of this module, you can limit the amount of goods in one hand, for one order. But if you do not fill in the "Maximum quantity" field in the product form, then this product can be purchased without restrictions.
The OpenCart product maximum quantity module can be useful if you are selling a single product, unique products in one instance or organizing a promotion for certain products and you need to set a limit on its purchase in one hand. In this way, the buyer will not be able to order more than the quantity of goods specified by you, for example, more than 1 piece or more than 3 pieces. When adding a specific product to the basket in an amount exceeding the established norm, only the maximum allowed amount will be added, and when the buyer tries to increase the amount of the product in the basket, he will see a warning that this product is limited for purchase.
Module installation instructions:
Upload the module in the admin panel in the "Extensions" : "Install".
