Question

我有以下问题。

我有一个jQuery手风琴，用于保存里程碑，在每个里程碑内，我有一个按钮，可以将事件添加到里程碑。这很好。我为每个输入分配名称的方式如下。

<input type="text" name="milestone_0_name">
<input type="text" name="milestone_0_start_date">
<input type="text" name="milestone_0_end_date">
<input type="text" name="milestone_0_description">
<input type="text" name="milestone_1_name">
<input type="text" name="milestone_1_start_date">
<input type="text" name="milestone_1_end_date">
<input type="text" name="milestone_1_description">
<input type="text" name="milestone_2_name">
<input type="text" name="milestone_2_start_date">
<input type="text" name="milestone_2_end_date">
<input type="text" name="milestone_2_description">
and so on...

所以之后当我向milestone_0添加事件时，例如生成的标记如下：

<input type="text" name="milestone_0_events_event_0_event_name">
<input type="text" name="milestone_0_events_event_0_event_start_date">
<input type="text" name="milestone_0_events_event_1_event_name">
<input type="text" name="milestone_0_events_event_1_event_start_date">

我不是$_POST数据处理的专家，因此我使用这种方式来了解哪些事件属于某个里程碑。问题是我用来识别形成里程碑的变量（里程碑的信息和每个事件信息）的函数有一个我似乎无法找到的问题。

功能是：

// Assign all $_POST data to $milestones
$milestones = $_POST;
print_r($milestones);


$milestoneNames = array();
$milestoneSize = array();

$default = "milestone_";
$indexOfMilestone=0;
$ind=0;
$text=$default.$indexOfMilestone;
$indexOfIteration=0;
$actualSize=0;
$change=false;

foreach($milestones as $ms)
{
    $currKey = KeyName($milestones,$indexOfIteration);
    echo $text.'.'.$currKey.'<br />';
    $pos = strripos($currKey, $text);
    if ($pos === false) 
    {
        $milestoneSize[$indexOfMilestone] = $indexOfIteration;
        $indexOfMilestone++;
        $text=$default.$indexOfMilestone;
    }
$indexOfIteration++;
}

print_r($milestoneSize);

对于测试数据，输出为：

    [milestone_0_name] => Milestone 1
    [milestone_0_start_date] => 12-4-25
    [milestone_0_end_date] => 12-4-26

    [milestone_1_events_event_1_event_start_date] => ff
    [milestone_1_events_event_2_event_name] => 6542
    [milestone_1_events_event_2_event_start_date] => ff
)

milestone_0.milestone_0_name

milestone_1.milestone_1_events_event_1_event_start_date
milestone_1.milestone_1_events_event_2_event_name
milestone_1.milestone_1_events_event_2_event_start_date

Array ( [0] => 16 )

问题出现在以粗体或** **标记的行中（不确定预览是否正常），milestone_0应为milestone_1。这个问题破坏了整个计数过程：）。

无论如何，如果这不是存储$_POST数据的好方法，我愿意接受改善数据存储的建议。

根据您的要求，以下是我将如何构建表单：

<ul class="milestones">

 <li>
  <label>
   Name
   <input type="text" name="milestones[0][name]">
  </label>
  <label>
   Start date
   <input type="text" name="milestones[0][start_date]">
  </label>
  <label>
   End date
   <input type="text" name="milestones[0][end_date]">
  </label>
  <label>
   Description
   <input type="text" name="milestones[0][description]">
  </label>
 <ul class="events">
  <li>
   <label>
    Name
    <input type="text" name="milestones[0][events][0][name]">
   </label>
   <label>
    Start date
    <input type="text" name="milestones[0][events][0][start_date]">
   </label> 
  </li>
  <li>
   <label>
    Name
    <input type="text" name="milestones[0][events][1][name]">
   </label>
   <label>
    Start date
    <input type="text" name="milestones[0][events][1][start_date]">
   </label> 
  </li>
 </ul>
</li>

 <li>
  <label>
   Name
   <input type="text" name="milestones[1][name]">
  </label>
  <label>
   Start date
   <input type="text" name="milestones[1][start_date]">
  </label>
  <label>
   End date
   <input type="text" name="milestones[1][end_date]">
  </label>
  <label>
   Description
   <input type="text" name="milestones[1][description]">
  </label>
 </li>

</ul>

这将产生如下的POST数据：

milestones => array(
 0 => array(
  name => "name",
  start_date => "2012-04-25",
  end_date => "2012-04-28",
  description => "desc",
  events => array(
   0 => array(
    name => "name0",
    start_date => "date0",
   ),
   1 => array(
    name => "name1",
    start_date => "date1",
   ),
  ),
 ),
 1 => array(
  name => "name",
  start_date => "2012-05-01",
  end_date => "2012-05-14",
  description => "desc",
 ),
)
