Question

我正在使用此页面http://loudev.com/中的jQuery MultiSelect - 在视觉上它一切正常，但我需要按照选择的顺序输出数据。

本文中jquery multiselect selected data order发布了一个解决方法，但我是初学者，需要一些帮助来实施解决方案。

理想情况下，我想在文本字段中输出所选项目。非常感谢任何帮助。

值存储在Keeporder数组中，因此您需要在PHP代码中获取keeporder数组

$hidden=array();
$hidden = $_POST['keeporder']; //get the values from the keeporder
print_r($hidden);
