Question

I want to remove the Login or register to post comments text from the page where I created a webform; is there any suggestion as to how can i use hook_link_alter() with this?

Answer 1

This code resides in comment.module file under the theme_comment_post_forbidden() function.

If you are using Drupal 7, you may use hook_node_view_alter or hook_entity_view_alter to modify the displayed content.

function foo_node_view_alter (&$build) {

  if ($build['#node']->type == 'webform') {
    // remove login or register to post comments
    unset($build['links']['comment']['#links']['comment_forbidden']);
    // remove add comments
    unset($build['links']['comment']['#links']['comment_add']);
  }

}

In case you want to use hook_link_alter in Drupal 6, use this code in your custom module

function comment_link_alter (&$links, $node) {

  if ($node->type == 'webform') {
    // remove register or login to post comments
    unset($links['comment_forbidden']);
    // remove add a comment
    unset($links['comment_add']);
  }

}
