Browse (or product listing) templates can be found in /html/templates/browse/.
They are loaded and filled with content in the file /html/shop.browse.php.
The concept is to define placeholders in the template and replaced them by the real contents on load. This is
done using the PHP function str_replace.
The following placeholders are used:
./.
4.2.3. Order Confirmation Email Templates
Order Confirmaton Email Templates define the layout of the confirmation email that is sent out to a user after
having placed an order.
These Email templates can be found in /html/templates/order_emails/.
They are loaded and filled with content in the file /classes/ps_checkout.php, function
email_receipt().
The concept is to define placeholders in the template and replaced them by the real contents on load. This is
done using the PHP function str_replace.
The following placeholders are used:
./.
4.2.4. Basket Templates
Basket templates control the layout of the basket.
The templates can be found in the directory /html/templates/basket/.
The special about the basket is that there are four different templates: Two for displaying the Cart content in-
cluding Tax (basket_b2c.html.php and ro_basket_b2c.html.php) and two for displaying the Cart
content without tax (adding it afterwards) - basket_b2b.html.php and ro_basket_b2b.html.php.
b2c = Business to Customer (prices include tax)
b2b = Business to Business (prices don't include tax)
The basket_ files are included in /html/shop.cart.php, /html/basket.php & /
html/ro_basket.php and in the /html/checkout.index.php except that the ro_basket_ file is dis-
played on the last step of the checkout (when the cart contents can't be modified any more - ro_basket = read
only basket).
The concept in the basket templates is another one than in the other template files, because loops are used. So
we have a minimum number of PHP statements, which can be easily understood by designers without much
PHP knowledge.
The variables which have been prefilled in /html/basket.php and /html/ro_basket.php are just
printed out in the templates.
5. Creating or modifying Extensions
Besides core modules, you can also add shipping and payment modules into VM. The concept of both - shipping
and payment modules is to provide an API with a defined specification (similar to an interface), where the mod-
ules can plug themselves in. The modules implement the required functions and thus can communicate with the
Shop and give their services.
