Auto-assign custom taxonomy?

May be you should check this reply. If it was a category taxonomy, the post settings has this option already. As you are trying with custom taxonomy, applying the action hook is the solution right now.

Thanks Tareq, worked perfectly!

Hi Tareq,

Thanks again, Although I have realised that it would be better if I could auto assign a tax based on the user (so I’m not creating a new forms for each user) so I tried the following but it doesn’t work (works when I substitute $user_id for $form_id)

function wpufe_set_default_cat( $post_id, $user_id ) {
  
    if ( 3 == $user_id ) { // change the number to your user ID
        wp_set_post_terms( $post_id, array( 49 ), 'ctax_instution' );  // the number is category ID
    }

    if ( 2 == $form_id ) { // change the number to your form ID
        wp_set_post_terms( $post_id, array( 39 ), 'ctax_instution' ); // the number is category ID
    }
}
  
add_action( 'wpuf_add_post_after_insert', 'wpufe_set_default_cat', 10, 2 );

Again, realise this is beyond the normal level of support, so understand if you don’t reply, but if it’s a quick fix then any advice would be appreciated. Thanks!

The second parameter in the function is $form_id, not $user_id. You can get the current users id by this: $user_id = get_current_user_id();. Now you can compare and set the taxonomy.
