如何确定Wordpress何时关闭并重定向到另一个站点

Question

I've been reading Stackoverflow for many years but this is the first time I ask a question.

I want to determine when a Wordpress site (www.first-domain.ro) is down (by Wordpress itself or Wordpress plugin problem) and then to redirect the user to a new site (www.second-domain.ro). I whant this to happen only is a problem with the site, otherwise user should stay on first site.

By "down" I mean that the site is not working because wordpress or a plugin generates an error preventing wordpress to load properly.

I have been reading on google and find nothing. Also on stackoverflow I find this Redirect to another site page if site one is down but I can't figure out how can be implemented on wordpress.

Thanks for you all!

Without knowing the exact steps involved, here's what I would do:

1. I assume 'down' means no database so the site cannot be used, so search the core WP files for the script that generates the error Error Establishing A Database Connection
2. Replace the generation of that error with header('Location: http://yourothersite.com'):

There are pre-existing plugins that allow you to modify the error message on the White Screen of Death . I assume you could modify one of those plugins to redirect instead of changing the message.

Here is the WordPress redirect function ...

wp_redirect( $url );
exit;
