SilverStripe Inheritage by SiteTree

Allows you to inherit any property from parent pages (any level). Check out the usage example to see how it works.

Features

• Loading information from direct or indirect parent page.

• This is only tested for db-fields. Has_one or has_many hasn't be confirmed.*

Usage

The following example shows a possible use case of two page types which have a fixed position in the information architecture and using inheritage to get the "color" field to the sublanding page.

<?php
/**
 * In the SiteTree this page will be directly under the homepage.
 *
 * URL structure /landing
 */
class LandingPage extends Page
{
    /**
     * @var array
     */
    $db = [
        'Color' => 'Varchar',
    ];
}
class LandingPage_Controller extends Page_Controller
{
    /* ... */
}

<?php
/**
 * In the SiteTree this page will be directly under the landing page.
 *
 * URL structure /landing/sublanding
 */
class SubLandingPage extends Page
{
    /* ... */
}
class SubLandingPage_Controller extends Page_Controller
{
    /* ... */
}

in SubLandingPage.ss you can do this now:

<div>
<% cached 'color', $Top.ID, $Top.LastEdited %>
$GetFromParentPage(Color)
<% end_cached %>
</div>

to retrieve the Color value set on the parent. Please ensure you apply suitable caching to any calls.

Requirements and installation

Requirements

• SilverStripe Framework and CMS ^3.0

Installation

1. Run the following command to install the package:

   # install the package
   composer require bringyourownideas/inheritage-by-sitetree;
   git add composer.json composer.lock;
   git commit -m 'MINOR: adding inheritage-by-sitetree';
   

2. Set up your Extension

   This can be done either via a yml configuration file (e.g. mysite/_config/config.yml):

   Page:
     extensions:
       InheritageBySiteTreeExtension

   or by checking the InheritageBySiteTreeExtension.php and adding the "non-extension" version of the module to your Page.php-file. The second option is more performant.

3. Run dev/build to load extension

   # run dev/build to load extension
   php ./framework/cli-script.php dev/build
