There is no need for the 'gform_after_submission' hook. Copy this: <a href="http://pastebin.com/tcvfg9L9" rel="nofollow">http://pastebin.com/tcvfg9L9</a> If you're using default posts try hooking to the action 'save_post', 'publish_post' or 'edit_post', etc. If you're using a custom post type, instead do 'save_my-post-type', where my-post-type is your post type's slug. cabaj on "Add Parent post category with hook/filter" https://legacy.forums.gravityhelp.com/topic/add-parent-post-category-with-hookfilter#post-60186 Thu, 24 May 2012 03:09:07 +0000 cabaj 60186@https://legacy.forums.gravityhelp.com/ I'm a PHP rookie so let me know if I'm out to lunch. I want to do something similar to Sascha and have implemented <a href="http://wordpress.org/support/topic/automatically-select-ancestor-terms-for-all-selected-terms?replies=2" rel="nofollow"> this function </a> that automatically sets the ancestor taxonomy term with the descendent is selected. It works great when publishing/editing a post from the backend - but not when a post is created with gravity forms. Any ideas on how this function can be hooked in with 'gform_after_submission'? Also trying to make this work with <a href="http://wordpress.org/search/front-end+editor" rel="nofollow">front-end editor</a> but don't know how to hook it in. <a href="http://pastebin.com/raw.php?i=P3fACKYq" rel="nofollow">http://pastebin.com/raw.php?i=P3fACKYq</a> sascha on "Add Parent post category with hook/filter" https://legacy.forums.gravityhelp.com/topic/add-parent-post-category-with-hookfilter#post-43031 Sat, 03 Dec 2011 09:59:58 +0000 sascha 43031@https://legacy.forums.gravityhelp.com/ Hi Dave, I used the following code and it works great! Thanks for your help/pointers!!! <pre><code>// select parent term automatically for the 'project_type' taxonomy in form #1 add_action('gform_after_submission_1', 'gform_parent_category'); function gform_parent_category($entry) { $created_post = $entry['post_id']; $child_ID = $entry["7"]; $term_object = get_term_by('id', $child_ID, 'project_type'); // replace project_type by chosen taxonomy $parent_ID = $term_object -> parent; wp_set_post_terms( $created_post, $parent_ID, 'project_type', true ); //replace project_type by chosen taxonomy }</code></pre> But instead of copying the code for each form, I wanted a flexible solution: I tried to use wp_get_post_terms instead. The only problem is that function returns an empty string! No idea why?!? Quite messy code as I tried different options: <pre><code>add_action('gform_after_submission', 'gform_parent_category'); function gform_parent_category($entry) { $created_post = $entry['post_id']; $post = get_post($entry["post_id"]); //$child_ID = $entry["7"]; //$term_object = get_term_by('id', $child_ID, 'project_type'); // replace project_type by chosen taxonomy $query_taxonomy = 'project_type'; $term_object = wp_get_post_terms($created_post, $query_taxonomy, array("fields" => "all")); // replace project_type by chosen taxonomy $product_terms = wp_get_object_terms($created_post, 'project_type', array("fields" => "all")); $parent_ID = $term_object -> parent; print_r($term_object); var_dump($term_object); var_dump($product_terms); var_dump($post); //$parent_ID = $term_object[parent]; echo $parent_ID; wp_set_post_terms( $created_post, $parent_ID, 'project_type', true ); //replace project_type by chosen taxonomy }</code></pre> Have you got any clues?

This function will return a category object which includes the "parent" property. This will be the ID of the parent category. Per my code example above, the $post_id is available in the $entry object as well. sascha on "Add Parent post category with hook/filter" https://legacy.forums.gravityhelp.com/topic/add-parent-post-category-with-hookfilter#post-42276 Mon, 28 Nov 2011 11:19:25 +0000 sascha 42276@https://legacy.forums.gravityhelp.com/ Hi there, I am using the "post category" field to populate the category of a post. This works well. What I would like to do though is: if a child is chosen on the form, then the parent (or even parents) are added automatically with the help of a hook/filter. Which would be the best filter to use and how would I go about adding that parent to the post category? In logic I would: 1. get the field value of the post category field into $child_category 2. use get_category_parent ($child_category) to save parent in $parent 3. wp_set_post_terms ($post_ID, $parent, $category, true) Do not know if that is right though. If it is the questions I have: what do I use for $post_ID and what do I use for $category? As always, any help is appreciated!
