First, thanks for the excellent plugin. I have been looking for exactly this for a long time. I can't tell you how happy I was to finally find just what I was looking for and to notice that it works so well. The only thing I'm really missing at the moment is the support for Custom Post Types and Custom Fields.
I have Custom Post Types with Custom Fields and am experiencing difficulties in letting users properly add those types of posts through WP User Frontend.
For example using Events Manager I have Events and Locations. Using the shortcode
[wpuf_addpost post_type="location"] it's possible to add a new Location, but that Location will be missing its mandatory custom fields like the address. I couldn't find a way to add these fields to the WPUF form.
The same is true for Custom Post Types with Custom Fields created by Types, for example. Types has its own settings to for example change the ordering of the custom fields, so you can choose whether you want for example Skype Login field to be displayed before or after Home Page URL.
Could WPUF be updated to either read the available Custom Fields and their order from the same settings, and/or to support manual entering of the fields to fill? For example like this:
[wpuf_addpost post_type="location" mandatoryfield="address" mandatoryfield="city" field="excerpt"]
Here two mandatory and one non-mandatory field would be added, in that order, in the end of the WPUF-generated submission form.
