The RecordLinkHandler

New in version 8.6: The RecordLinkHandler has been included in the Core with 8.6. Before, it had only been available as the third party extension “linkhandler”.

The RecordLinkHandler enables editors to link to single records, for example a single news record.

It is implemented in class \TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler of the system extension recordlist. The class is marked as @internal and contains neither hooks nor events.

In order to use the RecordLinkHandler it can be configured as following:

  1. Page TSconfig is used to create a new tab in the LinkBrowser to be able to select records.

    TCEMAIN.linkHandler.anIdentifier {
        handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
        label = LLL:EXT:extension/Resources/Private/Language/locallang.xlf:link.customTab
        configuration {
            table = tx_example_domain_model_item
        }
        scanAfter = page
    }
    

    You can position your own handlers in order as defined in the LinkBrowser API.

    The links are now stored in the database with the syntax <a href="t3://record?identifier=anIdentifier&amp;uid=456">A link</a>.

  2. TypoScript configures how the link will be displayed in the frontend.

    config.recordLinks.anIdentifier {
        // Do not force link generation when the record is hidden
        forceLink = 0
        typolink {
            parameter = 123
            additionalParams.data = field:uid
            additionalParams.wrap = &tx_example_pi1[item]=|&tx_example_pi1[controller]=Item&tx_example_pi1[action]=show
        }
    }
    

    Important

    Do not change the identifier after links have been created using the RecordLinkHandler. The identifier will be stored as part of the link in the database.

RecordLinkHandler page TSconfig options

The minimal page TSconfig configuration is:

TCEMAIN.linkHandler.anIdentifier {
    handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
    label = LLL:EXT:extension/Resources/Private/Language/locallang.xlf:link.customTab
    configuration {
        table = tx_example_domain_model_item
    }
}

The following optional configuration is available:

configuration.hidePageTree = 1
Hide the page tree in the link browser
configuration.storagePid = 84
The link browser starts with the given page
configuration.pageTreeMountPoints = 123,456
Only records on these pages and their children will be displayed

Furthermore the following options are available from the LinkBrowser Api:

configuration.scanAfter = page or configuration.scanBefore = page
Define the order in which handlers are queried when determining the responsible tab for an existing link
configuration.displayBefore = page or configuration.displayAfter = page
Define the order of how the various tabs are displayed in the link browser.

Example: news records from one storage pid

The following configuration hides the page tree and shows news records only from the defined storage page:

TCEMAIN.linkHandler.news {
    handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
    label = News
    configuration {
        table = tx_news_domain_model_news
        storagePid = 123
        hidePageTree = 1
    }
    displayAfter = mail
}

It is possible to have another configuration using another storagePid which also contains news records.

This configuration shows a reduced page tree starting at page with uid 42:

TCEMAIN.linkHandler.bookreports {
    handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
    label = Book Reports
    configuration {
        table = tx_news_domain_model_news
        storagePid = 42
        pageTreeMountPoints = 42
        hidePageTree = 0
    }
}

LinkHandler TypoScript options

A configuration could look like this:

config.recordLinks.anIdentifier {
    forceLink = 0

    typolink {
        parameter = 123
        additionalParams.data = field:uid
        additionalParams.wrap = &tx_example_pi1[item]=|
    }
}

The TypoScript Configuration of the LinkHandler is being used in sysext frontend in class TYPO3\CMS\Frontend\Typolink\DatabaseRecordLinkBuilder.

Example: news records displayed on fixed detail page

The following displays the link to the news on a detail page:

config.recordLinks.news {
   typolink {
      parameter = 123
      additionalParams.data = field:uid
      additionalParams.wrap = &tx_news_pi1[controller]=News&tx_news_pi1[action]=detail&tx_news_pi1[news]=|
   }
}

Once more if the book reports that are also saved as tx_news_domain_model_news record should be displayed on their own detail page you can do it like this:

config.recordLinks.news {
   typolink {
      parameter = 123
      additionalParams.data = field:uid
      additionalParams.wrap = &tx_news_pi1[controller]=News&tx_news_pi1[action]=detail&tx_news_pi1[news]=|
   }
}
