Hi, I have a php function that changes the html output of a wp-gallery. However I want to output the gallery-caption aswell, which my current output doesnt. Could anyone check my code and see how I could to this, if it is possible?
remove_shortcode('gallery');
add_shortcode('gallery', 'custom_size_gallery');
function custom_size_gallery($attr) {
$attr['size'] = 'full';
return gallery_shortcode($attr);
}
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
$output .= "<ul class='slides'>\n";
// Now you loop through each attachment
foreach ($attachments as $id => $attachment) {
// Fetch the thumbnail (or full image, it's up to you)
// $img = wp_get_attachment_image_src($id, 'medium');
// $img = wp_get_attachment_image_src($id, 'my-custom-image-size');
$img = wp_get_attachment_image_src($id, 'full');
$output .= "<li>\n";
$output .= "<img src=\"{$img[0]}\" width=\"{$img[1]}\" height=\"{$img[2]}\" alt=\"\" />\n";
$output .= "</li>\n";
}
$output .= "</ul>\n";
return $output;
}
