在 Wordpress 中循环遍历数组

Question

我创建了一个带有图片库上传的自定义帖子类型。现在我正在尝试在前端显示画廊。到目前为止，这就是我可以显示 1 张图片的内容，但是如果上传了多张图片，所有 url 都会卡在 src 标签中。所以我猜我应该遍历那个数组并分别吐出每个数组？那会是要走的路吗？如果是这样，我该怎么做？任何帮助表示赞赏。

<?php if (have_posts()) :  while (have_posts()) : the_post(); ?>

<?php
echo '<img src="'.get_post_meta($post->ID, 'gallery-upload', true).'">';    
?>

<?php endwhile; else: ?>
    <p><?php _e('No posts were found. Sorry!'); ?></p>
<?php endif; ?>

编辑：

这是返回的内容：

<img src="http%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F800x400-volbeat-mock1.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F1574_2_1.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F1576_2_1.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F1576_4_1.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F2244_2_1.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F300789_2349086884438_1168050047_32154880_1451576942_n.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F373795_278881222158106_278880528824842_834930_1454244548_n.jpeg%2Chttp%3A%2F%2Flocalhost%3A8888%2Fandreasmoulis%2Fwp-content%2Fuploads%2F2012%2F10%2F20110909-121141.jpeg">

查看function reference，get_post_meta 通常返回一个数组，除非第三个参数设置为true。这样的事情应该或多或少起作用。

<?php
foreach(get_post_meta($post->ID, 'gallery-upload') as $meta) {
  foreach(explode(',', $meta) as $src) {
    echo '<img src="'.htmlentities($src).'">';
  }
}
?>

编辑：显然画廊上传存储为逗号分隔值。将我上面的 sn-p 更新为 希望 帐户。
