Hidden category and visible category

  1. I have a form that lets visitors create a post. I want them to be able to choose what categories the post is in, but each post also needs to go into two additional categories. So have a Post Category field where people can check boxes for the category they want. I also have an admin-only field that should add the post to the two non-optional categories, but that field doesn't seem to be working - the post doesn't get saved in that category. I assume this is because I can't have two post category fields. So is there any way I can let users choose from a bunch of categories, but also force the post to have a few other categories?

    You would have to write some PHP to grab the currently selected categories, and edit the post category to append your own using the following hook: http://www.gravityhelp.com/documentation/page/Gform_post_data

  3. Can you provide a code example for you I would append categories? (Actually, it's a custom taxonomy.) The code examples make it clear how to change fields, but appending a category is more complicated.

  4. You can use the gform_after_submission hook http://www.gravityhelp.com/documentation/page/Gform_after_submission to update the post immediately after it's created. Your function would call the WordPress function wp_update_post http://codex.wordpress.org/Function_Reference/wp_update_post#Categories and you would pass in an array of category IDs.

  5. When I do this, it erases all of the form data except for the category. Here's my code:

    Any idea what I'm doing wrong?

    Thanks for your help!

  6. I fixed it. I needed to use wp_set_post_terms instead.
