钩入registered_post_type 并存储来自debug_backtrace(). 第三个条目应该是调用插件。

示例代码

add_action( \'registered_post_type\', \'track_post_types\', 10, 2);

function track_post_types( $post_type = NULL, $args = array() )
{
    static $tracked = array();

    if ( \'shutdown\' === current_filter() )
    {
        print \'<pre>$tracked = \' . esc_html( var_export( $tracked, TRUE ) ) . \'</pre>\';
        return;
    }

    if ( $args->_builtin )
        return;

    $backtrace = debug_backtrace();
    $tracked[ $post_type ] = $backtrace[3];

    add_action( \'shutdown\', __FUNCTION__ );
}
