Form action occur in controller for the section. What page or section are you looking at?

[rookiecoder]

actually I planned to do some custom work in shipping page. i would like to make a drop down menu to offer some sub-locations options for customer to choose. so I decided to use the "comment section" column instead of creating a new column in the database table. I would like to know how to pass the information from the drop down menu to the comment section. e.g example of desired forms like in this link: http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_radio_checked4

when the customer hits "send order" then it will be submitted to the "comment" section.
I know the form action for shipping occurs in shipping.php in controller and shipping.tpl(for layout). I am confused on how these two components links to each other.

thanks.

Each shipping method is an extension and has own model and controller. These are located in the extension/[default_----] directory.
What shipping do you edit?

I want to edit the "default store pick up" shipping method. so, that's mean I have to alter the shipping file in model and controller? I am still confused, but at least you guys shed some light on this.

Thanks.

There is no controller for storefront in "default store pick up". There is only model.
If you need to hook to shipping selection page, you need to look into checkout/shipping template and controller.
