For the purpose of this quote assume a standard site
exist ( complete ) with Virtuemart 2.0.4 and Joomla 2.5 -
for as far as the standard functionality allow.
Changes are required within the Virtuemart Sources. This
project has several phases and this document serves as a
summary of phases 1a and 1b.
We can make the location of the site known, but first want
a quotation for budgetary purposes. ( Phase 1a and 1b )
By basically adding a "stock" field to the "product_categories"
table and a "type" field to the
"Categories" table in Virtuemart the application is to
"buy" stock from a specific "location" ( a category type )
and alter the corresponding "stock" field.
Phase 1a ( Basic stock changes )
( Create a SQL file for all database changes - so it can be
applied & managed easier )
The solution must be able to handle a traffic flow of 360
Change the "Product_Category" table in Viruemart to have a "Stock"
field ( Integer )
Change the Category table in Viruemart to have a field ( Integer ) for
A Type "0" will be "standard" and "1" will be a "location" &
a field for an email address.
( Hard Coded at this stage )
All "location" categories will also be "hidden" ( standard
virtuemart ). ( Location fields will be edited manually )
There is a page that "shows" all the products of a particular
"non hidden" category. On the particular page add a control
( Combobox Selector ) which lists all the "location" type
categories ( including "All" ) and on selection will sort
the "product" further & display the subset of product belonging
to the particular category. Provide another Combobox selector
containing the items ( "All", "In stock" and "Not In Stock" ) -
On selection will filter the displayed product even further
based on the "Stock" field in the "category" table. ( This
selection should only be available if the "category" is
not selected as "All" )
By clicking on a product the "product details" page appears.
On this page the "Add to cart" button also apprears. Now:
( To add ) Add a Combobox selector for all "Location"
categories. Only allow "Add to cart" if a particular
"location" has been selected, bear in mind that ( the default )
selection of the "location" Combobox should be either "All" or the
specific "location" depending if this is known at time of
loading the page.
Add a "column" to the cart which will show the "location" field
( as per the Combobox selector at the time of "Adding to cart".
When finally clicking "Check Out Now" do a check whether stock
exist ( final check ) before creating an order - else warn
user. ( against appropriate field in the categories table )
When an order is placed it should also indicate the "location"
( This will also involve making a change to the database to
store the corresponding field )
The email which is sent to the "store" ( on placement of
order ) must be sent to the "email address" as per the
corresponding field in the "category" table for the particular
Phase 1b ( GUI minor )
Write an application in C# using Microsoft Visual Studio to
illustrate making a connection to a Virtuemart ( MySQL )
database & changing a sample field over a secure
connection, where database "connection details" are also
transmitted in a secure manner.
Other Phases: ( major )
Involves consultancy with respect to the following:
(b) Strategy to keep this "in line" with Virtuemart & Joomla
(d) Query Optimizations
