Custom Macro in JetEngine, um CCT Data über die ID des verknüpften CPTs abzurufen.php

#region Macro for JetEngine that looks up CCT values
/* This macro allows you to look up a CCT value from the connected CPT. Every custom content type that's connected to a CPT in JetEngine has a data column "cct_single_post_id" in which it saves the ID of the corresponding custom post type. Knowing that, you can access all the CCT keys with a custom lookup function and create a macro that wraps it and makes it relatively easy to use
 *
 * @param $prop_key - the CCT key you want to look up - defaults to "zmmt_email"
 * @param $lookup_column - the column in the CCT table that contains the ID of the corresponding CPT - defaults to "cct_single_post_id"
 * @param $table - the CCT table name - defaults to "zmmt_contacts"
 * 
 * If you want to look up the field "zmmt_email" for a custom post type "contact", all you need to use is %get_cct_value% thanks to the defaults
 * If you wanted to look up the field "zmmt_phone" for a custom post type "contact", you'd use %get_cct_value|zmmt_phone|cct_single_post_id|zmmt_contacts% or in short: %get_cct_value|zmmt_phone%
 *
 * Note! 
 * Register macros on jet-engine/register-macros action only, 
 * as the base macro class \Jet_Engine_Base_Macros is not available before that action; 
 * after it - all macros are registered already
