Magento – How to create advanced custom product options in general

custom-optionsextensions

It should be created a shop for eyeglasses. Therfore I want to create a product for each glasses frame and need to ask the customer for special details depending on his prescriptions.

The following dropdowns are required for each glasses frame:

The Sphere for the right eye (float values between -14.00 and +9.00 in steps of 0.25)
The Sphere for the left eye
The Cylinder for the right eye
The Cylinder for the left eye
The Axis for the left eye
The Axis for the right eye
Maybe some more…

I think advanced products will not do the trick because it makes no sense to create the glasses like i would do it with t-shirt colors for example. I have no stock of glasses, every glass will be created on request by the store owner.

I don't want to create the options for every new product manually in admin section.
It should be something like a product type glasses which implements these options.

I did some experiments with custom Input types based on this tutorial: http://magento.ikantam.com/qa/custom-input-types-custom-options

The questions are:

Is it the right way to use custom option types for that?
If not, what is the right way?
Is it possible in general to create one custom option type which results in 6 dropdowns with 6 possible values (maybe store it as serialized array in db) or do i have to create 6 custom option types?
Do you have further ideas or experience in extending magento like this?

I know the question is maybe too general and very basic. I am new to magento and cannot find anything about advanced options in the docs. Hope it is the right place here to ask this.

Thank you very much.

In order to create options with unlimited possibilities I would use mageworx extension advanced custom options

You can read what it does here.

I was amazed with results, conditional options (hide/show). You can create templates for glasses. You can use templates for each shape or for each grade. You can create 1 template and use to assign it as many products as you want, no need to recreate it for each product.

Yes, it cost money but it worth every penny!

Event1:checkout_cart_product_add_after

This event is fire when first time a product is cart for current session of current input values from frontend

Event2:checkout_cart_product_update_after

This event is fire when a current exiting cart item edited from edit link of cart item.

Event3:checkout_cart_update_items_after

This event is fire whenever cart items update from cart page.

As per as magento system, a cart item price change using setter functions setCustomPrice(), setOriginalCustomPrice of cart item Object.

Just like:

$EachCartitem->setCustomPrice($price);
$EachCartitem->setOriginalCustomPrice($price);
// Enable super mode on the product.
$EachCartitem->getProduct()->setIsSuperMode(true);

And using events fire an observer which is calculate price basic of your input fields.

Suppose: The radio button field name is My Checkbox and Text Box field Name is MyTestext.
