WordPress Image Gallerys的自定义HTML只输出一半的功能

I took the following code from an example and adjusted it so a standard gallery in wordpress would output as a Flexslider and Carousel. I can output one of them just fine, but I added additional *outputs for a Carousel as well, and now only the Carousel prints out. Any help on how I can get the whole thing to output would be appreciated

add_filter('post_gallery', 'my_post_gallery', 10, 2);
function my_post_gallery($output, $attr) {
global $post;

if (isset($attr['orderby'])) {
    $attr['orderby'] = sanitize_sql_orderby($attr['orderby']);
    if (!$attr['orderby'])
        unset($attr['orderby']);
}

extract(shortcode_atts(array(
    'order' => 'ASC',
    'orderby' => 'menu_order ID',
    'id' => $post->ID,
    'itemtag' => 'dl',
    'icontag' => 'dt',
    'captiontag' => 'dd',
    'columns' => 3,
    'size' => 'thumbnail',
    'include' => '',
    'exclude' => ''
), $attr));

$id = intval($id);
if ('RAND' == $order) $orderby = 'none';

if (!empty($include)) {
    $include = preg_replace('/[^0-9,]+/', '', $include);
    $_attachments = get_posts(array('include' => $include, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby));

    $attachments = array();
    foreach ($_attachments as $key => $val) {
        $attachments[$val->ID] = $_attachments[$key];
    }
}

if (empty($attachments)) return '';

// Here's your actual output, you may customize it to your need
$output = "<div class=\"wordpress-gallery\">
";
$output = "<div id=\"sliding\" class=\"flexslider flexslider--post-content\">
";
//$output .= "<div class=\"preloader\"></div>
";
$output .= "<ul class=\"slides flexslider__slides\">
";

// Now you loop through each attachment
foreach ($attachments as $id => $attachment) {
    // Fetch the thumbnail (or full image, it's up to you)
//      $img = wp_get_attachment_image_src($id, 'medium');
//        $imgThumbnail = wp_get_attachment_image_src($id, 'thumbnail');
        $img = wp_get_attachment_image_src($id, 'full');

    $output .= "<li class=\"slide flexslider__slide cover\">
";
    $output .= "<img src=\"{$img[0]}\" width=\"{$img[1]}\" height=\"{$img[2]}\" alt=\"\" />
";
    $output .= "</li>
";
}
$output .= "</ul>
";
$output .= "</div>
";
$output = "<div id=\"carousel\" class=\"flexslider flexslider--post-content-carousel\">
";
$output .= "<ul class=\"slides flexslider__slides\">
";
foreach ($attachments as $id => $attachment) {
    $imgThumbnail = wp_get_attachment_image_src($id, 'thumbnail');

    $output .= "<li >
";
    $output .= "<img src=\"{$imgThumbnail[0]}\" alt=\"\" />
";
    $output .= "</li>
";
}
$output .= "</ul>
";
$output .= "</div>
";
$output .= "</div>
";



return $output;

}

the html that gets outputed so far (it doesn't output the #sliding div, only the #carousel):

<div id="carousel" class="flexslider flexslider--post-content-carousel">
    <div class="flex-viewport" style="overflow: hidden; position: relative;">
        <ul class="slides flexslider__slides" style="width: 1400%; transition-duration: 0s; transform: translate3d(0px, 0px, 0px);">
