We want to add a new option in the product page of opencart - just like it says \Add to wishlist/Add to Compare, we want a link that will call a function.
Function code will be provided.
The cat/product details will be passed to the function.
We may also want to use this in Aceshop which is the Joomla 3 version of Opencart.
In both cases, the function will also need to pass user name so cart session information is available.
Has to be coded to permit upgrades of opencart/aceshop.
Please do not bother applying if you cannot demonstrate you have done this sort of work before.
