I have page /product/detail in my ecommerce with a submit form to cart/add
cart/add check form's field with form_validation
if there are errors (example missing color or size) redirect to product/detail
In product detail there aren't form_error('') and set_value('')
I tried another way, form_submit on product/detail and if there is a hidden variable
$_POST['action']=="add_cart"
proceed with form_validation ... but then I lose the benefits of being able to store the cached page
What is the right method to follow?
