Latest Stable Version TYPO3 12 TYPO3 11 Total Downloads Monthly Downloads PHPSTAN:Level 9 build:passing

This TYPO3 extension will automatically update the $GLOBALS['TYPO3_CONF_VARS']['SYS']['trustedHostsPattern'] variable when changes to the Site Configurations are made, reflecting the used domains in the system.

This is achieved with the Extension EXT:siteconfigurationevents which provides PSR-14 events when changing the Site config in the backend.

Additionally a command for CLI is available to update the trusted host pattern from the shell or during CI/CD or as a scheduler task via cron.

./vendor/bin/typo3 code711:updatetrustedhostfromsites -h        ✔  10118  16:52:23
  update SYS/trustedHostsPattern based on the site configuration


  -h, --help            Display help for the given command. When no command is given display help for the list command
  -q, --quiet           Do not output any message
  -V, --version         Display this application version
      --ansi|--no-ansi  Force (or disable --no-ansi) ANSI output
  -n, --no-interaction  Do not ask any interactive question
  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Calling the command with -v or --verbose will print the new value to the console additionaly to setting it in the config.

This extension WILL yield to the TYPO3_CONTEXT (or other similar) Environment Variable if Variations in the Site Configs are set.

A . will not be escaped (as it should be). This is a limitation as the escape character \ would be escaped again by the exporter somehow.
