lightboxのグループ化について
-
WordPress初心者です。
function.php内でギャラリーを追加した際にlightboxがグループになるように
タグを入れたいと思っています。そこで、function内に以下のように、画像に<a>が追加されるように投稿IDを取得する記述をしてみたのですが、うまく取得できません。
$link=str_replace('<a ','<a rel="lightbox[global $post_ID;]" ',
function内で投稿IDを取得し、リンク内に取り込む記述を教えてください。
なお、function内のフォトギャラリー制御箇所は以下の通りです。
function my_gallery_shortcode($attr) { global $post; static $instance = 0; $instance++; // Allow plugins/themes to override the default gallery template. $output = apply_filters('post_gallery', '', $attr); if ( $output != '' ) return $output; // We're trusting author input, so let's at least make sure it looks like a valid orderby statement 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' => 'li', 'icontag' => 'p', 'captiontag' => 'p', '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]; } } elseif ( !empty($exclude) ) { $exclude = preg_replace( '/[^0-9,]+/', '', $exclude ); $attachments = get_children( array('post_parent' => $id, 'exclude' => $exclude, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) ); } else { $attachments = get_children( array('post_parent' => $id, 'post_status' => 'inherit', 'post_type' => 'attachment', 'post_mime_type' => 'image', 'order' => $order, 'orderby' => $orderby) ); } if ( empty($attachments) ) return ''; if ( is_feed() ) { $output = "\n"; foreach ( $attachments as $att_id => $attachment ) $output .= wp_get_attachment_link($att_id, $size, true) . "\n"; return $output; } $itemtag = tag_escape($itemtag); $captiontag = tag_escape($captiontag); $columns = intval($columns); $itemwidth = $columns > 0 ? floor(100/$columns) : 100; $float = is_rtl() ? 'right' : 'left'; $selector = "gallery-{$instance}"; $gallery_style = $gallery_div = ''; if ( apply_filters( 'use_default_gallery_style', true ) ) $gallery_style = " <style type='text/css'> #{$selector} { /* style */ } #{$selector} ul{ /* style */ } #{$selector} .gallery-item { /* style */ } #{$selector} .gallery-icon{ /* style */ } #{$selector} img { /* style */ } </style> <!-- see gallery_shortcode() in wp-includes/media.php -->"; $size_class = sanitize_html_class( $size ); $gallery_div = "<div id='$selector' class='gallery galleryid-{$id} gallery-columns-{$columns} gallery-size-{$size_class}'><ul class='clearfix'>"; $output = apply_filters( 'gallery_style', $gallery_style . "\n\t\t" . $gallery_div ); $i = 0; foreach ( $attachments as $id => $attachment ) { $link = isset($attr['link']) && 'file' == $attr['link'] ? wp_get_attachment_link($id, $size, false, false) : wp_get_attachment_link($id, $size, false, false); $link=str_replace('<a ','<a rel="lightbox[global $post_ID;]" ', $link); $output .= "<{$itemtag} class='gallery-item'>"; $output .= " <{$icontag} class='gallery-icon'> $link </{$icontag}>";
よろしくお願いします。
