README
Overview
Provides an ErrorPage page type for the Silverstripe CMS, allowing CMS authors to set custom content for error page responses by error code. Error page responses are fully themed.
Installation
$ composer require silverstripe/errorpage
You'll also need to run dev/build
, which will generate a 500 and 404 error page.
Limitations
The functionally in this module was separated out from the Silverstripe CMS module and retains some existing issues. An issue of note is that static error pages are generated but are rarely served up, and rarely re-generated. This can lead to website visitors seeing a stale or broken page in the event of a 500 server error. Contributions are welcome, please open a pull request if you want to add a feature or fix a problem.
Upgrading from Silverstripe 3.x
API changes
ErrorPage.static_filepath
config has been removed.ErrorPage::get_filepath_for_errorcode
has been removedErrorPage::alternateFilepathForErrorcode
extension point has been removed
Upgrade code that modifies the behaviour of ErrorPage
ErrorPage has been updated to use a configurable asset backend, similar to the AssetStore
described above.
This replaces the ErrorPage.static_filepath
config that was used to write local files.
As a result, error pages may be cached either to a local filesystem, or an external Flysystem store (which is configured via setting a new Flysystem backend with YAML).
ErrorPage::get_filepath_for_errorcode()
has been removed, because the local path for a specific code is
no longer assumed. Instead you should use ErrorPage::get_content_for_errorcode
which retrieves the
appropriate content for that error using one of the methods above.
In order to retrieve the actual filename (which is used to identify an error page regardless of base
path), you can use ErrorPage::get_error_filename()
instead. Unlike the old get_filepath_for_errorcode
method, there is no $locale parameter.
In case that user code must customise this filename, such as for extensions which provide a locale value
for any error page, the extension point updateErrorFilename
can be used. This extension point should
also be used to replace any alternateFilepathForErrorcode
used.
class MyErrorPageExtension extends SiteTreeExtension { public function updateErrorFilename(&$name, &$statuscode) { if ($this->owner->exists()) { $locale = $this->Locale; } else { $locale = Translatable::get_current_locale(); } $name = "error-{$statusCode}-{$locale}.html"; } }

To Do
Theming
To apply a custom template for the error page you will need to create a ErrorPage.ss file in either templates/SilverStripe/ErrorPage/ErrorPage.ss
or templates/SilverStripe/ErrorPage/Layout/ErrorPage.ss
Detailed error messages
If you're using $this->httpError($code, $message)
in your codebase and want to include the message that is passed into that method, you can add the $ResponseErrorMessage
to your ErrorPage template. Use caution when including this information, as these messages are often intended for developers rather than end-users.
For example, one of your controllers may throw a 401 status code for some specific reason. Very broadly, a 401 means the request is Unauthorised; if your controller throws a 401, it can add also add a specific reason:
return $this->httpError(401, 'This is only accessible on Sunday before 10AM.');``` ```YourErrorPage.ss <h1>$Title</h1> <% if ResponseErrorMessage %> <p class="lead"> $ResponseErrorMessage </p> <% end_if %> </div>
These messages are appended to the ErrorPage template automatically when the site is in dev mode. You can disable this using the Config API. Setting this to false will also remove the $ResponseErrorMessage variable from your template.
