magento custom form on product page

Question

I'm new to Magento, and i need some conceptual guide and/or references. I need to create custom form that will be a part of product-info page (at it's bottom) and that will collect user input (email, size, color). Only some product will have this feature/form (it's up to admin). So, goal of this form will be to email store-admin about a product that is available in stock but not in wished size and/or color. Should i customize existing Contact us form or should i create fresh custom form in new module?
Form should submit data to admin via email along with name of the product.

Answer 1

Ok, so first create a .phtml file under app/design/frontend/[namespace]/[theme]/template/catalog/product/send_request.phtml

then, add this .phtml file reference in catalog.xml in /app/design/frontend/[namespace]/[theme]/layout/catalog.xml

<block type="core/template" name="customer_request" template="catalog/product/send_request.phtml"/>

below the : <label>Catalog Product View (Any)</label>

section but you should find to right section where to place ( you will find after a few try )

Finally, add your php logic into send_request.phtml file. The form contain that you implemented in send_request.phtml will available under product view page.
