+ Easily map your forms that create a post to a custom post type. Also map dropdown fields to custom taxonomies.

+ == Description ==
12
+
13
+ > This plugin is an add-on for the [Gravity Forms Plugin](http://bit.ly/getgravityforms "visit the Gravity Forms website").
14
+ > If you don't yet own a license of the best forms plugin for WordPress, go and [buy one now!](http://bit.ly/getgravityforms "purchase Gravity Forms!")
15
+
16
+ Gravity forms allows you to create posts from a form using post fields. The problem I found was that you cannot get the form to save to a custom post type without writing some php code. I wanted a way to easily map a form to a custom post type so that it would automatically save to the chosen custom post type. All you need to do is add a CSS Class Name of **"posttype-YOUR_POST_TYPE"** to the form and your work is done.
17
+
18
+ Eg. adding a CSS class name of "posttype-movies" will save the post to the custom post type of "movies".
19
+
20
+ I also wanted to link a dropdown to a custom taxonomy, so when the form is displayed, the dropwdown is populated with the terms from that custom taxonomy. And then when the post (or custom post type) is saved, it automatically links the post to the selected taxonomy term. All you need to do is add a CSS class of **"taxonomy-YOUR_TAXONOMY"** to the field.
21
+
22
+ Eg. adding a CSS class name of "taxonomy-actors" will link the dropdown to the "actors" custom taxonomy.
23
+
24
+ In summary, the plugin has the following features:
25
+
26
+ * Map a form to a custom post type
27
+ * Map a form dropdown field to a custom taxonomy
