Hello!

I added the code and now it shows the image in FB but now I receive and error while trying to see all the images of an author.

Here the code i applied to theme.php


--- Code: ---/******************************************************************************
** Section <<<pageheader>>> - START
******************************************************************************/
function pageheader($section, $meta = '')
{
    global $CONFIG, $THEME_DIR;
    global $template_header, $lang_charset, $lang_text_dir;

global $CPG_PHP_SELF, $LINEBREAK, $CURRENT_PIC_DATA, $CURRENT_ALBUM_DATA;
    if ($CPG_PHP_SELF == 'displayimage.php') {
        $meta .= '<meta property="og:url" content="' . $CONFIG['ecards_more_pic_target'] . 'displayimage.php?pid=' . $CURRENT_PIC_DATA['pid'] . '" />' . $LINEBREAK;
        $meta .= '<meta property="og:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $CURRENT_PIC_DATA['filepath'] . $CURRENT_PIC_DATA['filename'] . '" />';
    } elseif ($CPG_PHP_SELF == 'thumbnails.php') {
        $thumb = mysql_fetch_assoc(cpg_db_query("SELECT filepath, filename FROM {$CONFIG['TABLE_PICTURES']} WHERE aid = {$CURRENT_ALBUM_DATA['aid']} ORDER BY pid DESC LIMIT 1"));
        $meta .= '<meta property="og:url" content="' . $CONFIG['ecards_more_pic_target'] . 'thumbnails.php?album=' . $CURRENT_ALBUM_DATA['aid'] . '" />' . $LINEBREAK;
        $meta .= '<meta property="og:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $thumb['filepath'] . $thumb['filename'] . '" />';
    }

    $custom_header = cpg_get_custom_include($CONFIG['custom_header_path']);

    $charset = ($CONFIG['charset'] == 'language file') ? $lang_charset : $CONFIG['charset'];

    header('P3P: CP="CAO DSP COR CURa ADMa DEVa OUR IND PHY ONL UNI COM NAV INT DEM PRE"');
    header("Content-Type: text/html; charset=$charset");
    user_save_profile();

    $template_vars = array(
        '{LANG_DIR}' => $lang_text_dir,
        '{TITLE}' => theme_page_title($section),
        '{CHARSET}' => $charset,
        '{META}' => $meta,
        '{GAL_NAME}' => $CONFIG['gallery_name'],
        '{GAL_DESCRIPTION}' => $CONFIG['gallery_description'],
        '{SYS_MENU}' => theme_main_menu('sys_menu'),
        '{SUB_MENU}' => theme_main_menu('sub_menu'),
        '{ADMIN_MENU}' => theme_admin_mode_menu(),
        '{CUSTOM_HEADER}' => $custom_header,
        '{JAVASCRIPT}' => theme_javascript_head(),
        '{MESSAGE_BLOCK}' => theme_display_message_block(),
    );

    $template_vars = CPGPluginAPI::filter('theme_pageheader_params', $template_vars);
    echo template_eval($template_header, $template_vars);

    // Show various admin messages
    adminmessages();
}

/******************************************************************************
** Section <<<pageheader>>> - END
******************************************************************************/
--- End code ---

Here the error I receive:


--- Quote ---Template error

                    <div class="{CSS_CLASS}">

What do I wrong?
Thx in advance

Αndré:
Cannot confirm. Please post a link to your gallery and a link where we can see the error "in action". I assume it'll look like http://planepix.nl/thumbnails.php?album=lastupby&uid=4 (i.e. the "lastupby" meta album). That's at least what I tested and as you can see, the mod works as expected in that gallery.

Hi @André, I'm using your code but it seems like the SQL query isn't working ($thumb = mysql_fetch_assoc(cpg_db_query($sql));)

This is what I have on my theme.php file:

--- Code: ---global $CPG_PHP_SELF, $LINEBREAK, $CURRENT_PIC_DATA, $CURRENT_ALBUM_DATA;
    if ($CPG_PHP_SELF == 'displayimage.php') {
        $meta .= $LINEBREAK . '<meta property="og:url" content="' . $CONFIG['ecards_more_pic_target'] . 'displayimage.php?pid=' . $CURRENT_PIC_DATA['pid'] . '" />';
        $meta .= $LINEBREAK . '<meta property="og:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $CURRENT_PIC_DATA['filepath'] . $CURRENT_PIC_DATA['filename'] . '" />';
        $meta .= $LINEBREAK . '<meta property="twitter:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $CURRENT_PIC_DATA['filepath'] . $CURRENT_PIC_DATA['filename'] . '" />';
    } elseif ($CPG_PHP_SELF == 'thumbnails.php') {
        if ($CURRENT_ALBUM_DATA['aid']) {
            $album = $CURRENT_ALBUM_DATA['aid'];
            $sql = "SELECT filepath, filename FROM {$CONFIG['TABLE_PICTURES']} WHERE approved = 'YES' AND aid = '{$CURRENT_ALBUM_DATA['aid']}' ORDER BY pid DESC LIMIT 1";
        } else {
            $superCage = Inspekt::makeSuperCage();
            $album = $superCage->get->getAlpha('album');
            $sql = "SELECT filepath, filename FROM {$CONFIG['TABLE_PICTURES']} WHERE approved = 'YES' ORDER BY RAND() LIMIT 1";
        }
        $thumb = mysql_fetch_assoc(cpg_db_query($sql));
        $meta .= $LINEBREAK . '<meta property="og:url" content="' . $CONFIG['ecards_more_pic_target'] . 'thumbnails.php?album=' . $album . '" />';
        $meta .= $LINEBREAK . '<meta property="og:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $thumb['filepath'] . $thumb['filename'] . '" />';
        $meta .= $LINEBREAK . '<meta property="twitter:image" content="' . $CONFIG['ecards_more_pic_target'] . $CONFIG['fullpath'] . $thumb['filepath'] . $thumb['filename'] . '" />';
    }
