PHP数据处理困难

Question

我有以下问题。

我有一个jQuery手风琴，用于保存里程碑，并在每个里程碑内有一个按钮，用于将事件添加到里程碑。这工作正常。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... 

所以后来当我添加事件milestone_0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，所以我用这个办法知道属于什么事件专家到一定的里程碑。问题是我用来确定有多少变量形成里程碑（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); 

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_0_description] => abcdefg 
    [milestone_0_events_event_0_event_name] => asdg 
    [milestone_0_events_event_0_event_start_date] => ff 
    [milestone_0_events_event_1_event_name] => fghjk 
    [milestone_0_events_event_1_event_start_date] => ff 
    [milestone_0_events_event_2_event_name] => zxcv 
    [milestone_0_events_event_2_event_start_date] => ff 
    [milestone_0_events_event_3_event_name] => bnm, 
    [milestone_0_events_event_3_event_start_date] => zz 
    [milestone_0_events_event_4_event_name] => qwerty 
    [milestone_0_events_event_4_event_start_date] => zz 
    [milestone_0_events_event_5_event_name] => uiop 
    [milestone_0_events_event_5_event_start_date] => zz 
    [milestone_1_name] => Milestone 2 
    [milestone_1_start_date] => 12-4-26 
    [milestone_1_end_date] => 12-4-27 
    [milestone_1_description] => sadg ads asdgasdg adsga sgdsa gsad adsg asdg 
    [milestone_1_events_event_0_event_name] => 1234 
    [milestone_1_events_event_0_event_start_date] => ff 
    [milestone_1_events_event_1_event_name] => 4321 
    [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_0.milestone_0_start_date 
milestone_0.milestone_0_end_date 
milestone_0.milestone_0_description 
milestone_0.milestone_0_events_event_0_event_name 
milestone_0.milestone_0_events_event_0_event_start_date 
milestone_0.milestone_0_events_event_1_event_name 
milestone_0.milestone_0_events_event_1_event_start_date 
milestone_0.milestone_0_events_event_2_event_name 
milestone_0.milestone_0_events_event_2_event_start_date 
milestone_0.milestone_0_events_event_3_event_name 
milestone_0.milestone_0_events_event_3_event_start_date 
milestone_0.milestone_0_events_event_4_event_name 
milestone_0.milestone_0_events_event_4_event_start_date 
milestone_0.milestone_0_events_event_5_event_name 
milestone_0.milestone_0_events_event_5_event_start_date 
**milestone_0.milestone_1_name** 
milestone_1.milestone_1_start_date 
milestone_1.milestone_1_end_date 
milestone_1.milestone_1_description 
milestone_1.milestone_1_events_event_0_event_name 
milestone_1.milestone_1_events_event_0_event_start_date 
milestone_1.milestone_1_events_event_1_event_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) 

中标记为粗体或** **（不知道是否预览作品线路出现问题右），里程碑_0应该是里程碑_1。而这个问题会毁掉整个计数过程:)。

无论如何，如果这不是一个好的方式来存储来自$_POST的数据，我愿意提出改进我的数据存储的建议。

根据你的要求，这里的我会怎样结构形式：

<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> 

这将产生像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", 
), 
)
