Download Links

The Link checker module extracts links from your content when saved and
periodically tries to detect broken hypertext links by checking the remote
sites and evaluating the HTTP response codes. It shows all broken links in the
reports/logs section and on the content edit page, if a link check has been failed.
An author specific broken links report is also available in "My Account".

Installation

  1. Install linkchecker via Modules page.
  2. Go to Modules and enable the "Link checker" module.
  3. Go to Configuration -> Content authoring -> Link checker and enable the
    content types to scan.
  4. Under "Link extraction" check all HTML tags that should be scanned.
  5. Adjust the other settings if the defaults don't suit your needs.
  6. Save configuration
  7. Wait for cron to check all your links... this may take some time! :-)

If links are broken they appear under Reports -> Broken links.

If not, make sure cron is configured and running properly on your Backdrop
installation. The Link checker module also logs somewhat useful info about it's
activity under Reports -> Recent log messages.

Required

  1. For internal URL extraction you need to make sure that Cron always get called
    with your real public site URL (for e.g. https://example.com/cron.php). Make
    sure it's never executed with https://localhost/cron.php or any other
    hostnames or ports, not available from public. Otherwise all links may be
    reported as broken and cannot verified as they should be.

    To make sure it always works - it's required to configure the $base_url in
    the settings.php with your public sites URL. Better safe than sorry!

Known issues:

There are a lot of known issues in backdrop_http_request(). These have been solved
in HTTPRL. As a workaround it's recommended to use HTTPRL in linkchecker.
