Where are author avatars supposed to appear

[wacnstac]

I see code in the vbbridge.php file that is supposed to do something with avatars, but I don't see any on any of the WP pages or in the comments. Am I missing something?

Do your templates use the get_avatar() function at all?

[wacnstac]

Yes, I have called it from a template. It is also called somewhere in the commenting engine but I can't figure out where (I know it is being called for every comment posted because of my debug logs). I used Firephp to do some debugging on it. The code is expecting an integer for $u->user_id in your code but never getting one so if (!is_numeric($u->user_id)) { return; } is always returning.

Also it would help out a ton if I new what the function get_avatar was expecting in the $u parameter.

[Jeff]

$u is the user object. You pass that along to it..

I ended up modifying the get_avatar function with the following so I could pass in a user's vb id and get it to work correctly:

PHP Code:

function get_post_avatar($u, $size = '96', $default = '', $alt = false )
{
    global $vb;
    global $firephp;
    
    
/*    if (!is_numeric($u->user_id)) { return; }  */ 
    if (!is_numeric($u['userid'])) { return; }    

/*    $user = fetch_userinfo($u->user_id);  */ 
    $user = fetch_userinfo($u['userid']);

    if ($avatar = $vb->db->query_first("SELECT dateline, width, height FROM " . TABLE_PREFIX . "customavatar WHERE userid=" . intval($user['userid'])))
    {
        $safe_alt = esc_attr($user['username']);

        // using a custom avatar
        if ($vb->options['usefileavatar'])
        {
            $user['avatarurl'] = $vb->options['avatarurl'] . '/avatar' . $user['userid'] . '_' . $user['avatarrevision'] . '.gif';
        }

        else
        {
            $user['avatarurl'] = $vb->options['bburl'] . '/image.php?' . $vb->session->vars['sessionurl'] . 'u=' . $user['userid'] . "&dateline=$avatar[dateline]";
        }

        $default = $user['avatarurl'];

        $user['avatarurl'] = "<a class='vbridge_avatar_link' href='" . $vb->options['bburl'] . "/member.php?u={$user['userid']}'><img alt='{$safe_alt}' src='{$user[avatarurl]}' class='avatar avatar-{$size} photo avatar-default' width='{$size}' height='{$size}' border='0'/></a>";
    }


    
/*    return apply_filters('get_avatar', $user['geturl'], $u, $size, $default, $user['username']);   */
    return ($user['avatarurl']);
} 


I found out later that this caused an error in the word press backend when editing comments. I restored the get_avatar function to the old code to fix this, and renamed by new function. Two questions.

1. It sounds like I should be able to use the same function for both if I can figure out how to create a user object. Can you give me a little tutorial on how to do that?

2. How is the get_avatar function called in the WP commenting backend? I don't really see it in the code and avatars are not being associated with the comments in the backend.

3. I lied, one more.... I would also like to display the avatar of each user who comments on a post as in this page:

But I don't know what to pass from this template function to make that happen. You can see my attempts at trying to get a comment author which have failed.

PHP Code:

class thesis_comment_meta extends thesis_comment {
    function build($comment) {
        global $thesis_design;
        $this->meta = $thesis_design->comments['comments']['options']['meta'];

        if (is_array($this->meta)) {
            foreach ($this->meta as $element_name => $element)
                if ($element['show']) $output .= call_user_func(array($this, $element_name), $comment) . "\n";
        }

        thesis_hook_before_comment_meta();
        if ($output) echo $output;
        thesis_hook_after_comment_meta();
    }

    function author($comment) {
        return "<span class=\"comment_author\">" . get_comment_author_link() . "</span>";
    }

    function avatar($comment) {
        global $vb;
        global $firephp;
        
    

        $username = $comment['comment_author'];
        
        $firephp->log($comment,'Comment');
        
        
        if (is_object($vb)) 
        { 
            $vb_user_record = $vb->db->query_first("SELECT * from " . TABLE_PREFIX . "user where username = '" . $vb->db->escape_string($username) . "'");        
        }
        $vb_userid = $vb_user_record["userid"];
        

        $avatar = get_post_avatar($vb_user_record);
        
        
//        $avatar = get_avatar(get_comment_author_email(), $this->meta['avatar']['options']['size'], '');
        $author_url = get_comment_author_url();
        $avatar_output = (empty($author_url) || $author_url == 'http://') ? $avatar : "<a href=\"$author_url\" rel=\"nofollow\">$avatar</a>";
        return '<span class="avatar">' . apply_filters('thesis_avatar', $avatar_output) . '</span>'; #filter
    }

    function date($comment) {
        $timestamp = ($this->meta['date']['options']['time']) ? sprintf(__('%1$s at %2$s'), get_comment_date(stripslashes($this->meta['date']['options']['date_format'])), get_comment_time()) : get_comment_date(stripslashes($this->meta['date']['options']['date_format']));
        $text = ($this->meta['number']['show']) ? $timestamp : '<a href="#comment-' . get_comment_ID() . '" title="Permalink to this comment" rel="nofollow">' . $timestamp . '</a>';
        return '<span class="comment_time">' . apply_filters('thesis_comment_date', $text) . '</span>'; #filter
    }

    function number($comment) {
        if (!$GLOBALS['comment_vars']) return; else $c = $GLOBALS['comment_vars'];
        $number = ($c['current'] - 1) * $c['per_page'] + did_action('thesis_hook_before_comment_meta') + 1;
        return '<span class="comment_num"><a href="#comment-' . get_comment_ID() . "\" title=\"Permalink to this comment\" rel=\"nofollow\">$number</a></span>";
    }

    function edit($comment) {
        if (get_edit_comment_link()) return '<span class="edit_comment">' . apply_filters('thesis_edit_comment_link', '<a href="' . get_edit_comment_link() . '" rel="nofollow">' . __('edit', 'thesis') . '</a>') . '</span>'; #filter
    }
