尝试以下操作：
$value = get_post_custom_values( \'banda_postmeta\', $post->ID );
$value = unserialize("$value");
print_r($value);
echo $value[\'social_networks_url\'][\'twitter_url\'];
您的
social_networks_url 为空，请尝试回显这些值，它将回显该值。
echo $value[\'page_builder_settings\']."<br />";
echo $value[\'date_of_birth\']."<br />";
echo $value[\'location\']."<br />";
输出：
