Category not being assigned properly

Hi ForestNation,

I am having the exact same issue with a custom taxonomy on a custom post type. I can include the custom taxonomy successfully on the form, but then when it save it converts all terms to a #number.

The problem happens when the taxonomy is not hierarchical, so making it hierarchical will solve the problem.

Thanks Tareq, this worked.

I want my custom taxonomy to act like tags, though, not hierarchical…

Take a look here.

Thanks for the reply, Tareq.

That is similar to what I’m looking for but not exactly the same. I want to have a non-hierarchical custom taxonomy and have them in checkboxes on the form, not text inputs. That way the customer has to check off which custom taxonomy terms apply.

I can add this to the form, no problem. But the problem arises when the terms are saved and get converted into numbers.

For now I have changed the custom taxonomy to be hierarchical as a way around this, but not sure if that will cause problems down the line.

So open up /class/frontend-form.php line 270, you’ll see this code wp_set_post_terms( $post_id, $_POST[$taxonomy['name']], $taxonomy['name'] );, replace this with the code below and should be working:
[php]
if ( is_taxonomy_hierarchical( $taxonomy[‘name’] ) ) {
wp_set_post_terms( $post_id, $_POST[$taxonomy[‘name’]], $taxonomy[‘name’] );
} else {
if ( $tax ) {
$non_hierarchical = array();

foreach ($tax as $value) {
$term = get_term_by( ‘id’, $value, $taxonomy[‘name’] );
if ( $term && !is_wp_error( $term ) ) {
$non_hierarchical[] = $term->name;
}
}

wp_set_post_terms( $post_id, $non_hierarchical, $taxonomy[‘name’] );
}
} // hierarchical
[/php]

that seems to be working! thank you very much Tareq. we could mark this as resolved.

(for anyone else, the filename in question is /class/frontend-form-post.php…)
