Feature: #79121 - Implement hook in typolink for modification of page params

Description

A new hook has been implemented in ContentObjectRenderer::typoLink for links to pages. With this hook you can modify the link configuration, for example enriching it with additional parameters or meta data from the page row.

Impact

You can now register a hook via:

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typolinkProcessing']['typolinkModifyParameterForPageLinks'][] = \Your\Namespace\Hooks\MyBeautifulHook::class;

Your hook has to implement TypolinkModifyLinkConfigForPageLinksHookInterface with its method modifyPageLinkConfiguration(array $linkConfiguration, array $linkDetails, array $pageRow). In $linkConfiguration you get the configuration array for the link - this is what your hook can modify and has to return. $linkDetails contains additional information for your link and $pageRow is the full database row of the page.

For more information as to which configuration options may be changed, see TSRef.

public function modifyPageLinkConfiguration(array $linkConfiguration, array $linkDetails, array $pageRow) : array
{
    $linkConfiguration['additionalParams'] .= $pageRow['myAdditionalParamsField'];
    return $linkConfiguration;
}
