WP hooks navigation: Home/browse • Actions index • Filters index
To save our bandwidth, we show only a snippet of code around each occurence of the hook. View complete file in SVN (without highlighting).
The best way to understand what a hook does is to look at where it occurs in the source code.
do_action( "hook_name" )apply_filters( "hook_name", "what_to_filter" ).Remember, this hook may occur in more than one file. Moreover, the hook's context may change from version to version.

| 136 | // insecure content warnings. This is not attempted if the admin and frontend |
| 137 | // are on different domains to avoid the case where the frontend doesn't have |
| 138 | // ssl certs. Domain mapping plugins can allow other urls in these conditions |
