Customising the shop module


It is most likely that you as a website developer/designer will want to customise the shop module to look and work as your client would like.

There are a number of configuration options to be set in your _config.php file. See Configuration

Also see the list of recipes and also see Development

Where to put your customisations?


It may not be clear where to put your customisations of SilverStripe, and the shop module. Here are some tips:

  • Look for the same idea already implemented in a SilverStripe module, or shop submodule. You can save time if you find the work has already been done.
  • Create extensions and decorators. This is the cleanest way of creating customisations. It may introduce slight overhead processing time however.
  • You should create themes in the themes directory, and split out into module directories, eg:

    • themes
      • mytheme
      • mytheme_shop
      • mytheme_blog
  • Site-specific code should go into mysite/code.

Overriding core code


Hopefully you don't need to override core SilverStripe, or shop module code.

but if you need to, you have a few options:

  • Rewrite the file directly. Not recommended if you aren't using a version control system like git. Git allows creating branches of code, which you can use to store your customisations.
  • Create Sub-classes. Extend the parent class, and overwrite whatever methods you need to. For example: MyCustomCategory might extend ProductCategory. Or MyCustomProduct might extend Product. You can sometimes replace the use of one class with another by adding the following to your _config.php file: Object::useCustomClass("OldObject","NewObject");

    If these are bugfixes, or additional features that the core code would benefit from, please feel free to contribute back.

Theming / Templates


There are a number of templates you can customise to create your desired look for the shop module. The Order template has been modularised using SilverStripe's <% include TemplateName %> tag to provide varying degrees of freedom to customise. The order template is used in both the Account page to display summaries of past orders, and it is also used with the email template. To make your customisations you need to create your own corresponding version of the template/partial-template with the same name in your mysite/templates folder or the themes folder.

More about developing themes here. Note: some templates are needed in multiple places to work.

Sub modules


Sub-modules provide additional functionality that remains separate from the main shop module to keep the core code as minimal as possible. If you are creating custom/different functionality for your website, and it could be used on other sites, then you should put this code into a submodule.
