CFS – Campo Contact Form 7

Tihs plugin creates a new type of field into Custom Field Suite: the user can select any form generated with Contact Form 7.

You can get the form HTML using CFS()->get( 'form_field_id' ) or the form ID using CFS()->get( 'form_field_id', get_the_ID(), array( 'format' => 'raw' ) ).

Note: Obviously, this plugin requires both Custom Field Suite and Contact Form 7 to work.
