You can do this with the raw html...
-
In your browser, call up the product info screen of the product you want to feature.
-
After the page has loaded, view the page source (html).
You will see that the page html elements are neatly sectioned by COMMENT TAGS, for example:
<!--bof Form start-->
<form name="cart_quantity" action="http://www.YOUR-SITE.com/index.php?main_page=product_info&cPath=168_178&products_id=1865&action=add_product" method="post" enctype="multipart/form-data">
<!--eof Form start-->
and (towards the bottom of the file)...
<!--bof Form close-->
</form>
<!--eof Form close-->
The ones above you WILL ABSOLUTELY NEED, as they drive the submission of the add to cart form.
There are some that you won't need - such as the "previous-next" buttons, but you may need to add the attributes / quantity discounts / (if there are any).
Naturally, you may want the images and the price, and you WILL NEED the "Add to Cart" element as well.
Enclose everything between the OPENING FORM tag and the CLOSING FORM tag, and then - in your EZPages Editor - toggle to HTML mode (the <> menu icon) and PASTE the html where you want it.
Because EZPages data is stored in the database, it's not possible to include php commands in these pages, because the core code has already assembled the page by the time the EZPages data is called in...
