我正在尝试将带有 jQuery UI(可排序)的表的顺序保存到 PHP 数组中。
我已经大大简化了它,但这是它的基本思想。我有一个嵌入了可排序列表的表格。该表是通过 PHP 生成的,涉及包含在另一个文件 ( )foreach
中的多维数组。config.php
config.php
:
<?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'),
);
?>
表(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>
脚本(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 neworder 值 ( $_POST['neworder']
) 保存到数组中config.php
。
我想我必须使用 PHP 函数uasort()
(或uksort()
, uksort()
)与 . 的组合file_put_contents
来保存新的订单config.php
。
所以是这样的:
<?php
if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['neworder'])) {
/*
Here file_put_contents in config.php the new order. So:
$config = array(
"mno" => array('item 5'),
"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'),
);
Becomes:
$config = array(
"abc" => array('item 1'),
"def" => array('item 2'),
"ghi" => array('item 3'),
"jkl" => array('item 4'),
"mno" => array('item 5'),
"pqr" => array('item 6'),
"stu" => array('item 7'),
"vwx" => array('item 8'),
);
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.
