datelink module for Silverstripe
This module allows you to create dated urls, that is, links that have the year and month preceeding the url segment., (*1)
This is useful if you want your blog posts, or other date-specific sections of the website, to indicate when they
were posted. This follows the same style as wordpress, and other blog applications., (*2)
For instance, if you had a blog with urls like, (*3)
http://www.mysite.com/blog/heres-an-awesome-post, (*4)
You could turn these links into:, (*5)
http://www.mysite.com/blog/2012/2/heres-an-awesome-post, (*6)
Dated style urls can only be applied to subpages, grouped under common holder pages of a list of specified types., (*7)

Requirements
Installation Instructions
- Extract all files into the 'datelink' folder under your Silverstripe root, or install using composer
composer require "tractorcow/silverstripe-datelink": "3.1.*@dev"
- Ensure that the assets folder is properly writable. This module will save an xml file under assets/_datelink and will
need write permissions
- Configure the page options. See the Configuration section.
- Run dev/build in order to generate and cache routes.
The reason for using a cached XML file for storing routing patterns is that database access is not available before
routes are initialised. All required parent pages and years are extracted during dev/build to create distinct patterns
that silverstripe can use during routing, to prevent clashes between it and the default page routing. These routes are
then simply read from the XML file and set in the routing table each page load., (*8)
Configuration
See DateLink.yml for the basic configuration options., (*9)
Class Filter Configuration
To setup date customised links you should configure the class names of each child and parent relations. The only
mandatory property to set is the DateLink.holder_classes config property to specify the parent classes of all dated
urls., (*10)
DateLink:
holder_classes:
- 'BlogHolder'
By default all children of the specified classes will have dated urls applied to them. In order to further filter out
these classes an additional filter may be applied, the DateLink.child_classes config property., (*11)
For example, to filter only 'BlogEntry' pages:, (*12)
DateLink:
child_classes:
- 'BlogEntry'
URL Configuration
You can customise the URL layout using constants, year, month (name/number), day of the month, and even day of the
week using the configuration property DateLink.url_pattern, (*13)
DateLink:
url_pattern: '$ParentLink!/$Year!/$Month!/$URLSegment!//$Action/$ID/$OtherID'
The following pattern placeholders can be used here:
* $ParentLink! - The parent page URL (mandatory)
* $URLSegment! - The URLSegment of the current page (mandatory)
* $Year! - Year (mandatory)
* $Month! - Month number
* #$Month! - Month number (leading zeros)
* $MonthName! - Month name (full name)
* $Date! - Day of month
* #$Date! - Day of month (leading zeros)
* $Weekday! - Day of the week (full name), (*14)
All wildcards prior to the '//' must be qualified with a trailing '!', (*15)
Date Configuration
The field which holds the date for each page can be customised by one of two ways:, (*16)
- The
DateLink.default_date_field config option will set the default field. By default this is 'Created'
- Override the
getRouteDate function in your Page class to return the date value that should be used for that page.
