Very good idea, Keith. I bundeled this into a separate class that I can easily use in the plugin boilerplate. Assuming you have the ACF files in a folder “acf” in a directory “lib”:
<?php
// Exit if accessed directly
if ( !defined( 'ABSPATH' ) )exit;
/**

*

*/
class ss_acf_integrate {
/**

*

* @access protected
* @var string $plugin_name The string used to uniquely identify this plugin.
*/
protected $plugin_name = '';
/**
* The current version of the plugin.
*

*/
protected $version = '1.0.0';
/**

Call this class in the function load_dependencies() like this:
/**
* The class for integrating ACF
*/
if ( !class_exists( 'ss_acf_integrate ' ) ) {
require_once plugin_dir_path( dirname( __FILE__ ) ) . 'includes/class-ss_acf_integrate.php';
new ss_acf_integrate( $this->get_plugin_name(), $this->get_version() );
}
I decided to have a little switch to enable/disable the ACF admin. In your wp-config.php add
// ACF Admin
define ('ACF_SHOW_ADMIN', true);
where obviously true means show the ACF admin and false means hide it.
Thanks again for your fantastic starting point.
