我已经非常简化了,但这是它的基本想法.我有一个表中嵌有可排序的列表.该表通过PHP foreach生成,涉及包含在另一个文件(config.PHP)中的多维数组.

config.PHP文件：

<?PHP
$config     = array(
    "mno" => array('item 5'),"abc" => array('item 1'),"ghi" => array('item 3'),"pqr" => array('item 6'),"jkl" => array('item 4'),"vwx" => array('item 8'),"def" => array('item 2'),"stu" => array('item 7'),);
?>

table(index.html)：

<table cellpadding="2" cellspacing="0" align="center" id="mytable">
    <tbody>

<?PHP
    $i = 0;
    include 'config.PHP';
    foreach($config AS $name => $value){
        $item = $value[0];
        echo '
        <tr id="'.$name.'-'.$i++.'">
            <td>'.$item.'</td>
        </tr>';
    }
?>

</tbody>
</table>

scripts(index.html)：

<!-- Add jQuery library -->
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<!-- Add jQuery UI library -->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<script type="text/javascript">
    $(document).ready(function() {
        var fixHelper = function(e,ui) {
            ui.children().each(function() {
                $(this).width($(this).width());
            });
            return ui;
        };
 
        $("#mytable tbody").sortable({
            helper: fixHelper,opacity: 0.5,scroll: false,update: function () {
                var data = $('#mytable tbody').sortable('serialize');
                $.post("edit.PHP",{'neworder': data});
            }
        }).disableSelection();
    });
</script>

排序工作正常,但我不知道如何将新的顺序值($_POST [‘neworder’])保存到数组中是什么在config.PHP中.

我想我必须用file_put_contents的组合使用uasort()(或uksort(),uksort())的PHP函数来保存config.PHP中的新命令.

所以这样的事情

<?PHP
if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['neworder'])) {
    /* 
    Here file_put_contents in config.PHP the new order. So:
    $config     = array(
        "mno" => array('item 5'),);
 
    Becomes:
    $config     = array(
        "abc" => array('item 1'),"mno" => array('item 5'),);
 
    After this is send by Jquery UI:
    neworder:abc[]=1&def[]=6&ghi[]=2&jkl[]=4&mno[]=0&pqr[]=3&stu[]=7&vwx[]=5
 
    I've tried this:
        $filename = 'config.PHP';
 
        $lines = file( $filename,FILE_IGNORE_NEW_LINES );
        $linenumber = 2;
        foreach( $_POST['neworder'] AS $name => $val){
            $phost = $val[0];
 
            $lines[$linenumber] = ' "'.$name.'" => array(\'' . $phost . '\'),';
            $linenumber++;
        }
 
        file_put_contents( $filename,implode( "\n",$lines ) );
 
    But the '$val' is not send with Jquery only the order.
 
    */  
}
