PHP數據處理困難

Question

我有以下問題。

我有一個jQuery手風琴，用於保存里程碑，並在每個里程碑內有一個按鈕，用於將事件添加到里程碑。這工作正常。我爲每個輸入分配名稱的方式如下。

<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... 

所以後來當我添加事件milestone_0例如生成的標記如下：

<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數據處理，所以我用這個辦法知道屬於什麼事件專家到一定的里程碑。問題是我用來確定有多少變量形成里程碑（里程碑的信息和每個事件信息）的函數有一個我似乎無法找到的問題。

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); 

測試數據，輸出爲：

[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) 

中標記爲粗體或** **（不知道是否預覽作品線路出現問題右），里程碑_0應該是里程碑_1。而這個問題會毀掉整個計數過程:)。

無論如何，如果這不是一個好的方式來存儲來自$_POST的數據，我願意提出改進我的數據存儲的建議。

Answer 1

根據你的要求，這裏的我會怎樣結構形式：

<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> 

這將產生像POST數據：

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", 
), 
)
