+ * https://gravitywiz.com/
+ *
+ * By default, the Advanced Post Creation add-on does not allow you to map multiple fields to a taxonomy nor does it
+ * allow you to set terms by ID.
+ * 
+ * This snippet allows to specify multiple fields on a form that have been populated with term IDs (we recommend 
+ * [Populate Anything][1] for this) and to set the taxonomy/terms based on those IDs for the generated post.
