I have created a custom post type with an image gallery upload. Now I am trying to display the gallery on the front end. This is what I have so far that works to display 1 image, but if multiple images are uploaded all the urls get stuck in the src tag. So I'm guessing I should loop through that array and spit out each one separately? Would that be the route to go and if so how can I accomplish this? Any help is appreciated.

<?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; ?>

EDIT:

This is what is being returned:

<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">

查看函数引用，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).'">';
  }
}
?>
