How to tell if Jetpack’s Photon is active?

2 comments

1. We just committed a new function to Jetpack Trunk, and it should be enabled in the next release, Jetpack::is_module_active() —

   http://plugins.trac.wordpress.org/changeset/716884

   Then you can just call:

   if( class_exists( 'Jetpack' ) && Jetpack::is_module_active( 'contact-form' ) ) {}
   

   Or at least, you will once the next version releases, and the user has their Jetpack updated. 🙂 If you’d like to preserve the backward compatability, you can just do:

   if( class_exists( 'Jetpack' ) && in_array( 'contact-form', Jetpack::get_active_modules() ) {}
   

   It’s a slightly tidier way than querying the option directly.

2. Checking for the option value jetpack_active_modules.

   

   ^{Searching for photon in wp_options is how I found the option_name.}

   The following prints the option as an admin notice:

   add_action( 'admin_notices', 'wpse_75103_active_jetpack_modules' );
   
   function wpse_75103_active_jetpack_modules() 
   {
       if( !current_user_can( 'delete_users' ) )
           return;
   
       $jetp = get_option( 'jetpack_active_modules' );
   
       $photon_active = ( in_array( 'photon', $jetp ) ) ? 'is' : 'is not';
       echo '<h1>Photon ' . $photon_active . ' active</h1>';
   
       echo '<h2>All JetPack Options</h2>';
       echo '<pre>' . print_r( $jetp, true ) . '</pre>';
   }

   The following is the result with all modules activate.
   The key numbers are in the order by which the modules were activated and should not be used as reference.
