Logging links resulting in a 404-error.

[formmailer]

Hi!

I would like to get an notification/overview of links that result in a 404 error on my site. This includes links on external sites and internal links.

Would it be possible to save the $HTTP_REFERERs resulting in a 404, somewhere in the database?

I think that your best bet for this is your apache log:

grep ' 404 ' /path/to/access_log

Though that's assuming you are logging referrers in your access log. I also like Google Webmaster tools for finding 404s.

You could always create a http404.php template file for ProcessWire, and then have it log the info somewhere:

$log = new FileLog($config->paths->logs . '404.txt'); 
$log->save($sanitizer->text($_SERVER['HTTP_REFERER']) . ' => ' . $sanitizer->text($_SERVER['REQUEST_URI'])); 

But the above may be overkill since info about 404s is already be tracked in apache logs and web analytics.

Thank you Ryan. I was looking for a way to make the 404's easily available for editors, so that they could react on these.

But I guess you are right, probably it would be overkill to do this. They can get the data from the webstats and the webmaster tools.
