我的函数中有一个函数。php文件我需要稍微修改一下，但在正确执行时遇到了问题。此函数更改Wordpress的图库标记，使其更加html5友好。它工作得很好，只是我想将整个库包装在一个div中，例如<div id="sort">. （我想包装图片库，而不是整个帖子。）
我很难理解如何将其添加到此函数中：
//Gallery Code Filter
add_filter( \'post_gallery\', \'my_post_gallery\', 10, 2 );
function my_post_gallery( $output, $attr) {
global $post, $wp_locale;
static $instance = 0;
$instance++;
// 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\' => \'figure\',
\'icontag\' => \'dt\',
\'captiontag\' => \'figcaption\',
\'columns\' => 3,
\'size\' => \'thumbnail\',
\'attachment\' => \'large\',
\'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}";
$output = apply_filters(\'gallery_style\', "");
$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, true, false);
$output .= "<{$itemtag} class=\'item\'>";
$output .= "
$link
";
if ( $captiontag && trim($attachment->post_excerpt) ) {
$output .= "
<{$captiontag}>
" . wptexturize($attachment->post_excerpt) . "
</{$captiontag}>";
}
$output .= "</{$itemtag}>";
if ( $columns > 0 && ++$i % $columns == 0 )
$output .= \'\';
}
$output .= "
<br>\\n";
return $output;
}

我刚刚在函数中添加了一个div，请参见代码中的注释：
<?php
add_filter( \'post_gallery\', \'my_post_gallery\', 10, 2 );
function my_post_gallery( $output, $attr )
{
global $post, $wp_locale;
static $instance = 0;
$instance ++;
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\' => \'figure\',
\'icontag\' => \'dt\',
\'captiontag\' => \'figcaption\',
\'columns\' => 3,
\'size\' => \'thumbnail\',
\'attachment\' => \'large\',
\'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,

else

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}";
$output = apply_filters( \'gallery_style\', \'\' );
$i = 0;
// The div
$output .= \'<div id="sort">\';
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, true, false );
$output .= "<{$itemtag} class=\'item\'>";
$output .= "$link";
