I want to set the category of a post using a custom field.
I tried the following code, but it doesn't work. I suspect that '' wpv-post-category "is wrong.

"wpcf-beitrag_typ" is the custom field in the form

<?php
/**
* New custom code snippet (replace this with snippet description).
*/

toolset_snippet_security_check() or die( 'Direct access is not allowed' );

// Put the code of your snippet below this comment.

add_action('cred_save_data','func_update_kategorie',10,2);
function func_update_kategorie($post_id,$form_data) {

if ($form_data['id']==751) {

$kategorie = get_post_meta($post_id, 'wpcf-beitrag_typ', true);

update_post_meta($post_id, 'wpv-post-category', $kategorie);
}
}

Hello, if you want to add a taxonomy term to the post, you should use the function wp_set_object_terms: https://developer.wordpress.org/reference/functions/wp_set_object_terms/

The update_post_meta function is used to set a custom field value. Taxonomies are not the same as custom fields, so the wp_set_object_term function is better. Example:

wp_set_object_terms($post_id, 'term-slug', 'category', false);

Instead of term-slug you can use:
A single term slug, single term id, or array of either term slugs or ids. Will replace all existing related terms in this taxonomy. Passing an empty value will remove all related terms.

The last parameter false will delete all the other category terms from this post. If you use true instead of false, the existing category terms will not be deleted.

Let me know if you have questions about this.
