The plugin will create a custom post type, taxonomies and hopefully import the form upon activation. The sample you have based on gform_pre_render_## presents a challenge in that with the import I won't necessarily know the form #.</p> <p>Can gform_field_value_dropdownfieldname accept array responses to populate the dropdowns? I'm using the Custom Post Types plugin which makes this selection dead simple for the standard dropdown type, but doesn't appear to support custom field dropdowns (<a href="http://wordpress.org/support/topic/plugin-gravity-forms-custom-post-types-cant-get-taxonomies-to-list-out?replies=5" rel="nofollow">http://wordpress.org/support/topic/plugin-gravity-forms-custom-post-types-cant-get-taxonomies-to-list-out?replies=5</a>) </p> https://legacy.forums.gravityhelp.com/topic/using-custom-taxonomies-in-dropdown-field#post-17714 Fri, 04 Feb 2011 18:30:17 +0000 David Smith 17714@https://legacy.forums.gravityhelp.com/ <p>I updated the code to correct this error: <a href="http://pastie.org/1529752" rel="nofollow">http://pastie.org/1529752</a> </p> https://legacy.forums.gravityhelp.com/topic/using-custom-taxonomies-in-dropdown-field#post-17646 Fri, 04 Feb 2011 10:11:55 +0000 jacquesbez 17646@https://legacy.forums.gravityhelp.com/ <p>David </p> <p>I tried the script you suggested but get an error.

Not post meta/custom field data. However, you could certainly modify this code to pull in custom field values. In either event the code would go in your themes functions.php file. </p> https://legacy.forums.gravityhelp.com/topic/using-custom-taxonomies-in-dropdown-field#post-17600 Thu, 03 Feb 2011 18:57:40 +0000 shshshea 17600@https://legacy.forums.gravityhelp.com/ <p>I am trying to do something similar (I think). I have a site where each blog post represents a different location. Each location offers different programs. I was hoping to create one "Get More Info" Gform to place within a widget section. I need the Program Drop Down menu to be populated by the content found in the Programs Custom Field box of each blog post. Hopefully that makes sense. </p> <p>Is that what the code linked to above is written to do? And if so, are we supposed to place it in the functions.php file?</p> <p>Thanks for your help. </p> https://legacy.forums.gravityhelp.com/topic/using-custom-taxonomies-in-dropdown-field#post-17587 Thu, 03 Feb 2011 16:48:51 +0000 shshshea 17587@https://legacy.forums.gravityhelp.com/ <p>+2 </p> https://legacy.forums.gravityhelp.com/topic/using-custom-taxonomies-in-dropdown-field#post-17307 Mon, 31 Jan 2011 13:19:36 +0000 David Smith 17307@https://legacy.forums.gravityhelp.com/ <p>Hi Jacques, I have not had an opportunity to looks at this but in the mean time here is some old code where I've done something like this before. I put some notes in here on what you will need to update to make this work with you form.
