我正在尝试将砌体实现到 wordpress 默认画廊。我修改了gallery_shrotcode()以调整图像大小并将砌体类和属性添加到画廊 div。我也改变<style>了一点

这是更新的代码：

function rf_gallery($output, $attr) {
$post = get_post();

static $instance = 0;
$instance++;

if ( ! empty( $attr['ids'] ) ) {
    // 'ids' is explicitly ordered, unless you specify otherwise.
    if ( empty( $attr['orderby'] ) )
        $attr['orderby'] = 'post__in';
    $attr['include'] = $attr['ids'];
}

// 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 ? $post->ID : 0,
    'itemtag'    => 'dl',
    'icontag'    => 'dt',
    'captiontag' => 'dd',
    'columns'    => 3,
    'size'       => 'thumbnail',
    'include'    => '',
    'exclude'    => ''
), $attr, 'gallery'));

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

if ( !empty($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) ) {
    $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);
$icontag = tag_escape($icontag);
$valid_tags = wp_kses_allowed_html( 'post' );
if ( ! isset( $valid_tags[ $itemtag ] ) )
    $itemtag = 'dl';
if ( ! isset( $valid_tags[ $captiontag ] ) )
    $captiontag = 'dd';
if ( ! isset( $valid_tags[ $icontag ] ) )
    $icontag = 'dt';

$columns = intval($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} {
            margin: auto;
        }
        #{$selector} .gallery-item {
            float: {$float};
            text-align: center;

        }
        #{$selector} img {

        }
        #{$selector} .gallery-caption {

            margin-right: 0;
        }
        /* see gallery_shortcode() in wp-includes/media.php */
    </style>";
$size_class = sanitize_html_class( $size );
$gallery_div = "<div id='$selector' class='gallery galleryid-{$id} gallery-columns-{$columns} js-masonry' data-masonry-options='{ \"columnWidth\": 200, \"itemSelector\": \".gallery-item\" }'>";
$output = apply_filters( 'gallery_style', $gallery_style . "\n\t\t" . $gallery_div );

$i = 0;
foreach ( $attachments as $id => $attachment ) {
    if ( ! empty( $attr['link'] ) && 'file' === $attr['link'] )
        $image_output = wp_get_attachment_link( $id, array(300,600), false, false );

    else
        $image_output = wp_get_attachment_link( $id, array(300,600), true, false );

    $image_meta  = wp_get_attachment_metadata( $id );

    $orientation = '';
    if ( isset( $image_meta['height'], $image_meta['width'] ) )
        $orientation = ( $image_meta['height'] > $image_meta['width'] ) ? 'portrait' : 'landscape';

    $output .= "<{$itemtag} class='gallery-item'>";
    $output .= "

            $image_output
        </{$icontag}>";
    //if ( $captiontag && trim($attachment->post_excerpt) ) {
    //    $output .= "
    //        <{$captiontag} class='wp-caption-text gallery-caption'>
    //        " . wptexturize($attachment->post_excerpt) . "
    //        </{$captiontag}>";
    //}
    $output .= "</{$itemtag}>";
    if ( $columns > 0 && ++$i % $columns == 0 )
        $output .= '<br style="clear: both" />';
}

$output .= "
        <br style='clear: both;' />
    </div>\n";

return $output;
}
add_filter("post_gallery", "rf_gallery",10,2);

这段代码使布局完全混乱，而且很奇怪，当浏览器重新加载时它会改变。更准确地说，内联样式中的顶部位置随着每次加载而变化，以产生三种不同的布局。

以下是出现的两种布局的图像： 1号

2号

3号

最后一张图片是正确的布局。

请让我知道我做错了什么。

谢谢！

问题是调用脚本的顺序，html 是在脚本之前加载的，这个线程中的答案为我解决了这个问题。

根本不需要编辑画廊短代码，那真的很乱，为什么不简单地使用现有的类呢？

var container = document.querySelector('.gallery');
var msnry = new Masonry( container, {
  // options
  columnWidth: 200,
  itemSelector: '.gallery-item'
});
