Add support for ajax comments module

same problem here!

I've tried the 'patch' on http://drupal.org/node/455708, but no luck!

Somebody any ideas?

Looking into this for the D7 version and want to leave some notes here...

Adding support for ajax comments requires #comment-wrapper:

photos.image.inc
_photos_comment ...

<?php
    // Add support for ajax comments on image page.
    $output['comments']['#prefix'] = '<div id="comment-wrapper-nid-' . $node->nid . '">';
    $output['comments']['#suffix'] = '</div>';
?>

After posting one comment the form is reloaded by ajax comments and the fid is no longer available, so the second comment and any following comments will post to the album node and appear under the image temporarily, but will not be there if the page is reloaded because the fid was not available to link that comment with the image.

Example image url:
photos/image/86

Ajax comments url:
system/ajax

Code in photos.module to add image fid to comment form:
photos_form_alter ...

<?php
    if (isset($form_state['input']['photos_fid'])) {
      $fid = $form_state['input']['photos_fid'];
    }
    elseif (arg(0) == 'photos' && is_numeric(arg(2))) {
      $fid = arg(2);
    }
    elseif (arg(1) == 'reply' && is_numeric(arg(3))) {
      $fid = db_query('SELECT fid FROM {photos_vote} WHERE cid = :cid',
        array(':cid' => arg(3)))->fetchField();
    }
    if (isset($fid)) {
      $form['comment']['photos_fid'] = array(
        '#type' => 'hidden',
        '#value' => $fid,
      );
    }
?>

So, we need some way to pass the fid (86 in this example) to the comment form after it is reloaded by the ajax comments module.

Adding the following code to the ajax_comments.module ajax_coments_submit_js function solves the problem by passing the photos_fid to the new form.

<?php
      if (isset($form_state['input']['photos_fid'])) {
        $new_form_state['input']['photos_fid'] = $form_state['input']['photos_fid'];
      }
?>
