显示所有自定义帖子字段和值，除非为空

我希望抓取给定帖子的所有自定义帖子元字段，并将它们显示在页面上，这是我用以下代码完成的。

但是，我想检查（！empty（））是否为自定义post元数据，并且不打印任何为空的值。

除此之外，这应该是非常直接的，但我会感谢你的帮助。

<?php
$custom_fields = get_post_custom();
    foreach ( $custom_fields as $field_key => $field_values ) {
        if(!isset($field_values[0])) continue;
        if(in_array($field_key,array("hits","_wp_trash_meta_time","SKU","sub-category-2","sub-category-1","_wp_trash_meta_status","old_price","price","qty","additional_notes","buy_link","customlist1","customlist2","featured","image","images","_edit_lock","_edit_last","_thumbnail_id","_sexybookmarks_permaHash","_sexybookmarks_shortUrl"))) continue;
    foreach ( $field_values as $key => $value )                             
    echo \'<li><strong>\' . $field_key . \':</strong> \' . $value . \'</li>\';
}
?>

// Loop through all fields, grab the content and assign it to a new array foreach ( get_post_custom() as $custom ) $new_custom[] = array_shift( $custom ); // Get rid of empty fields $new_custom = array_filter( $new_custom );
