More Information
wp_get_attachment_url() doesn’t distinguish whether a page request arrives via HTTP or HTTPS.
Using wp_get_attachment_url filter, we can fix this to avoid the dreaded mixed content browser warning:
add_filter('wp_get_attachment_url', 'honor_ssl_for_attachments'); function honor_ssl_for_attachments($url) { $http = site_url(FALSE, 'http'); $https = site_url(FALSE, 'https'); return ( $_SERVER['HTTPS'] == 'on' ) ? str_replace($http, $https, $url) : $url; }
