Product matrix extension


This extension provides a product matrix for Simple Invoices. This means that in invoice creation you can select a product and then a list of attributes and values will be display that are relevant to that product for you to choose from.

ie. - Product = T-Shirt - Product Attributes = Size, Colour - Product Values = Size (Small, Medium, Large), Colour (Red, White, Blue)

In the Manage Product Values screen you can add new values and assign them to certain attributes, and in edit/add products you can assign attributes to a certain product.


This extension is currently work in progress



There are modifications required to the Simple Invoices database for this extension to work

They are detailed in ./extensions/product_matrix/install/matrix.sql

You can just import this .sql file into phpMyAdmin for the db changes to be applied


You need to edit ./config/config.php and enable the product matrix extension, refer how_to_enable_an_extension for how to do this

Hi, I'have installed the last version of simpleInvoices and then try to install product_matrix extension and import the matrix.sql, but I don't find the config.php in the /config directory but only config.ini that have a different syntax. I read the tutorial about installing extension but probably I dont' understand very well.

Hello, I have been trying to do the same, and finally I did it.

Probably the documentation is not updated, what I did was activated this extension with the “extension screen”. The activation extensions values is in the database, the file “config.php” doesn't exists I think is the old method.

In other hand, this extensions have many errors or… I didn't make a correct installation.
