Add custom options programmatically to associated products

by Vivek Shahi   Last Updated July 11, 2018 23:09 PM

I have been working on showing custom options of simple product for grouped product. I am done with initial phase of allowing required custom option product and then showing it on frontend. I have modified checkout/cart/add to add products with custom option to cart. This is also working fine. But I see products are being added twice to cart. Once with custom option and another one without custom option. I have debugged app/code/core/Mage/Catalog/Model/Product/Type/Grouped.php . Here, protected function _prepareProduct(Varien_Object $buyRequest, $product, $processMode) is responsible for adding product to cart. I tried adding custom option values of products from here. But couldn't succeed.

Note:- Here I am not trying to create new custom options. I just want to set the values of custom option.

Any help will be appreciated. Thanks in advance.
