Using action hook to add custom taxonomy to form.

Hi Everyone,

I’m using the latest version of WPUF PRO to create my front-end forms using action hooks.

I’ve been able to hook in a custom taxonomy multi-select dropdown based on the method outlined here by @j-grandin .

The taxonomy dropdown shows up and saves properly, but on the “Edit Post” page the selected taxonomy terms do not show up as selected. It just shows the “Nothing selected” title, even though terms *are* selected.

Could someone please take a look at my code below and check out the place where selected terms are supposed to get echoed as ‘selected=”selected”‘?

Thanks,
Alex
