For performance reasons, we insist on disabling the "Command-Scheduler" in Settings (enable tl_settings.disableCron) and run the cron jobs by a dedicated cronjob within your servers crontab.

Contao 3:

* * * * * wget -O /dev/null -q https://[DOMAIN-NAME]/system/cron/cron.php --no-check-certificate


The module adds a checkbox to news archive to activate (or deactivate) newsalert for archives. It also add a checkbox to the news articles form to set (or unset) an article sent (by setting unsent newsalert will be triggered again for said article).

The overview about sent messages is placed within the news archive section (News -> Newsalert). The management of the receivers is found withing the newsalert section (News -> Newsalert -> Newsalert receivers)


Add topic source

To add a topic source, your topics class needs to implement the NewsTopicInterface and has to be registered within $GLOBALS['HUH_NEWSALERT']['TOPIC_SOURCE'].


$GLOBALS['HUH_NEWSALERT']['TOPIC_SOURCE']['newsarchives'] = \HeimrichHannot\ContaoNewsAlertBundle\Components\NewsArchiveTopics::class;

Notification center tokens

ContaoNewsalert uses Notification Center for e-mail sending. Following tokens are added to news_posted type (in addition to the default ones):


Frontend autocompletion

We recommend Chosen to add a search field to the topic select element. It's already used by Contao in the backend.
