php - Reload php scandir() without refresh

Question

I'm using this script:

$userdir = '../../'.$id.'/';
    $files2 = scandir($userdir);
    $ignore = array(".", "..");


    foreach ($files2 as $value) {

        if(in_array($value, $ignore)){
        }
        else {

    echo '<img class="clickableimg" id="'.$value.'" src="../../'.$id.'/'.$value.'" />';   }
    }

This is from a form when the users can choose an image and upload new images.

The problem is that I want the scandir() to fire up again when the user clicks on "refresh" without loosing form data.

Any ideas?

我也倾向于使用 AJAX（换句话说，将数据传递给外部 PHP 脚本而不重新加载页面）。

互联网上和 SO 上都有成千上万的例子。当我学习 ajax 时，这非常方便：http ://www.w3schools.com/ajax/default.asp
