選擇框中的父子樹

我正嘗試在無限數量的父項和子項的選擇框中創建一棵樹。和我的選擇框（html部分）應該是Access，我已經給出了下圖。選擇框中的父子樹

我有一個「categories」數組，它有兩個主節點數量不限的節點（父 - 子）。兩個主陣列名稱是[scope] => selectboxFirst和[scope] => selectboxsecond。有一個parentid以4000開頭。我不能在代碼中硬編碼parentid。數組來自解碼的json字符串。

我不知道如何循環這個數組，並在一個單獨的選擇框中顯示兩個數組。

在我發佈的示例數組中，一個數組內有兩個主數組，但它們也可以在其他數組中。我不知道如何在兩個選擇框中顯示父母孩子。

所有[scope] => selectboxFirst類別將顯示在第一個選擇框中，並在第二個選擇框中顯示[scope] => selectboxsecond類別。

輸出shoiuld是這樣的。例如：相對應的ID來選擇框裏面有選項訪問

Electronics 
--Keyboards 
--Phones 
----HTC DESIRE Z 
----HTC ONE X 
-------Camera 
-------Battety 
Food 
--Fruits 
----Apple 
----Watermelon 
--Vegetables 
----Carrot 
----Onion 

**inside select box . for eg: <select><option value='4001'>Access</option></select>**

沿着我至今這麼多，但它顯示的一切.Still沒有得到

$json = json_decode($string,TRUE); 


//echo "<pre>"; 
//print_r($json); 

recursive($json,$level=1); 
function recursive($array, $level = 1){ 
    foreach($array as $value){ 
     //If $value is an array. 
     if(is_array($value)){ 
      //We need to loop through it. 
      recursive($value, $level + 1); 
     } else{ 
      //It is not an array, so print it out. 
      echo str_repeat("-", $level), $value, '<br>'; 
     } 
    } 
}

看看遞歸。 – msfoster 2014-10-16 16:48:33

我不知道我的父母id.It可以是2或3任何數字。我很困惑如何找到沒有指定parent_id深度。 – aniltc 2014-10-16 17:08:20

這個數據結構應該是什麼結構？選擇框只能是平面列表。 – 2014-10-16 18:39:18

以下代碼將遞歸遍歷您的數據結構並創建選項列表。由於它非常簡單，我將爲您創建select標籤。我已使用PHP_EOL在每個選項之後添加換行符，以使HTML代碼更易於閱讀。

foreach ($data['categories'] as $c) { 
    # scope is $c['scope'] 
    echo "Starting " . $c['scope'] . PHP_EOL; 
    # calling the function on the categories data  
    recurse($c['categories']); 
    echo "Finished " . $c['scope'] . PHP_EOL; 
} 

function recurse($arr, $level = 0){ 
    # we have a numerically-indexed array. go through each item: 
    foreach ($arr as $n) { 
     # print out the item ID and the item name 
     echo '<option value="' . $n['id'] . '">' 
     . str_repeat("-", $level) 
     . $n['name'] 
     . '</option>' 
     . PHP_EOL; 
     # if item['children'] is set, we have a nested data structure, so 
     # call recurse on it. 
     if (isset($n['children'])) { 
      # we have children: RECURSE!! 
      recurse($n['children'], $level+1); 
     } 
    } 
}

輸出：

Starting selectboxFirst 
<option value="4001">Access</option> 
<option value="4010">-mine</option> 
<option value="4011">-yours</option> 
<option value="4002">Communication</option> 
<option value="4015">-Physician</option> 
<option value="4016">--Helps blsys Understand</option> 
<option value="4017">--Listens</option> 
<option value="4021">-Clinical ps</option> 
<option value="4022">--yours ps/datasssss</option> 
<option value="4024">-etc</option> 
<option value="4003">Office</option> 
<option value="4026">-Facilities/Environment</option> 
<option value="4027">--Noise</option>

（等）

您可以用適當的代碼爲「啓動selectboxFirst/selectboxSecond」。

它仍然顯示爲一個列表，而不是在選擇框中.ID可以顯示在頁面中。只有顯示的名稱和ID應該附加在選項內作爲值，例如： – aniltc 2014-10-16 21:05:40

編輯您的問題以添加此信息，並且您還應該指定您也需要幫助生成HTML。 – 2014-10-16 21:06:59

謝謝我添加了我試圖顯示這種方式，但沒有得到 – aniltc 2014-10-16 21:15:03
