As I would like to allow users print their names with comments I added a new field called comment_name. To not have 2 fileds with name I used the code to unset filed "name" from comment.module

function user_add_node_form_comment_form_alter(&$form, &$form_state) {
return $form;

But after adding a comment I receive an error message

Notice: Undefined index: name in function comment_form_validate() (line 2127 in file D:\sites\theme\www\modules\comment\comment.module).
Notice: Undefined index: mail in function comment_form_validate() (line 2140 in file D:\sites\theme\www\modules\comment\comment.module).
Notice: Undefined index: homepage in function comment_form_validate() (line 2143 in file D:\sites\theme\www\modules\comment\comment.module).

I guess it because I unset a form that has to validate if user logged in or not but don't know how to solve it.

P.S. Also I use the Ajax Comments Module

You should try this if you just want to hide the comment default name field !

function user_add_node_form_comment_form_alter(&$form, &$form_state) {
  $form['author']['name']['#access'] = FALSE;
  • thank you, your variant of function works, but if user user "preview button" before posting comment drupal returns an error: "Notice: Undefined index: format in function comment_preview() (line 2057 in file D:\sites\theme\www\modules\comment\comment.module). Notice: Undefined property: stdClass::$thread in function ajax_comments_entity_prepare_view() (line 375 in file D:\sites\theme\www\sites\all\modules\ajax_comments\ajax_comments.module)."
