Page title API¶
In order to keep setting the page titles in control, you can use the PageTitle API. The API uses page title providers to define the page title based on page record and the content on the page.
Based on the priority of the providers, the
\TYPO3\
will check the
providers if a title is given by the provider. It will start with the highest
priority and will end with the lowest priority.
By default, the Core ships two providers. If you have installed the system
extension SEO, the provider with the (by default) highest
priority will be the \TYPO3\
.
When an editor has set a value for the SEO title in the page properties of the
page, this provider will provide that title to the
Page
. If you have not installed the SEO system
extension, the field and provider are not available.
The fallback provider with the lowest priority is the
\TYPO3\
. When no other title is
set by a provider, this provider will return the title of the page.
Besides the providers shipped by the Core, you can add own providers. An integrator can define the priority of the providers for his project.
Create your own page title provider¶
Extension developers may want to have an own provider for page titles. For example, if you have an extension with records and a detail view, the title of the page record will not be the correct title. To make sure to display the correct page title, you have to create your own page title provider. It is quite easy to create one.
First, create a PHP class in your extension that implements the
\TYPO3\
, for example by
extending \TYPO3\
. This will
force you to have at least the get
method in your class. Within
this method you can create your own logic to define the correct title.
namespace Vendor\Extension\PageTitle;
use TYPO3\CMS\Core\PageTitle\AbstractPageTitleProvider;
class MyOwnPageTitleProvider extends AbstractPageTitleProvider
{
public function setTitle(string $title)
{
$this->title = $title;
}
}
Usage example, for example, in an Extbase controller:
$titleProvider = GeneralUtility::makeInstance(MyOwnPageTitleProvider::class);
$titleProvider->setTitle('Title from controller action');
Define priority of PageTitleProviders¶
The priority of the providers is set by the TypoScript property
config.
. This way an integrator is able to set
the priorities for his project and can even have conditions in place.
By default, the Core has the following setup:
config.pageTitleProviders {
record {
provider = TYPO3\CMS\Core\PageTitle\RecordPageTitleProvider
}
}
The sorting of the providers is based on the before
and
after
parameters. If you want a provider to be handled before a
specific other provider, just set that provider in the before
,
do the same with after
.
If you have installed the system extension SEO, you will also get a second provider. The configuration will be:
config.pageTitleProviders {
record {
provider = TYPO3\CMS\Core\PageTitle\RecordPageTitleProvider
}
seo {
provider = TYPO3\CMS\Seo\PageTitle\SeoTitlePageTitleProvider
before = record
}
}
First the Seo
(because it will be handled before
record
) and, if this providers did not provide a title, the
Record
will be checked.
You can override these settings within your own installation. You can add as many providers as you want. Be aware that if a provider returns a non-empty value, all provider with a lower priority will not be checked.
