如何在codeigniter中生成类别树？`

你好我想生成类似n级别的wordpress类别树。这是我的例子数组。如何在codeigniter中生成类别树？`

     [39] => stdClass Object 
      (

       [ParentCat] => 98 
       [Auto] => 142 
       [flgActive] => 1 
      )

现在父类别和子类别关系在ParentCat字段和自动字段之间。

现在我不得不尝试此代码

foreach($tree as $el){ 
      $thisref = &$refs->{$el->Auto}; 
       foreach($el as $k => $v){ 
       @$thisref->{$k} = $v; 
      } 
      if($el->ParentCat == 0){ 
       $reportTree->{$el->Auto} = &$thisref; 
      } 
      else{ 
       $refs->{$el->ParentCat}->children->{$el->Auto} = &$thisref; 
      } 
      $reportTree; 
     }

我有一个阵列中的元素800，并尝试以产生具有上面的代码树。但单个一些元素插入数组100次。但它应该只插入一次。

父子关系例如这里我从数组中取2个元素。

[1] => stdClass Object 
      (
       [Id] => 12878 
       [CoaName] => Income 
       [CompId] => 1 
       [ParentCat] => 0 
       [Auto] => 1 
       [flgActive] => 1 
      ) 

     [2] => stdClass Object 
      (
       [CoaName] => I · ROOM REVENUE 
       [ParentCat] => 1 
       [Auto] => 23 
       [flgActive] => 1 
      )

现在第二元件具有ParentCat值1和第一元件具有自动1个所以第一个元素是第二元件的母体。所以，你可以请建议我如何做到这一点。感谢

如果我理解正确的话 - 下面应该工作：

首先由你的ID密钥分配阵列（根据你的php比如有不总是一个id - 但我认为这是复制错误）

$arrTreeById = array(); 
$arrTree = array(); 

foreach($arrTree AS $objItem) 
{ 
    $arrTreeById[$objItem->Id] = $objItem; 
    $objItem->arrChilds = array(); 
}

和分配后您只需孩子的添加到父母

foreach($arrTreeById AS $objItem) 
{ 
    if (isset($arrTree[$objItem->ParentCat])) $arrTree[$objItem->ParentCat]->arrChilds[] = $objItem; 
    if ($objItem->ParentCat == 0) $intStartingKey = $objItem->Id; 
} 

print_r($arrTree[$intStartingKey]);

还是我失去了一些东西这里？

我开发这个功能只是传递数组这个功能

function buildArrayTree($items){ 
     $ref = array(); // track references 
     $Childrens = array(); // new array 

     // menu reference since can't push directly later 
     foreach($original = &$items as $item) 
     { 
      if($item->ParentCat == 0) 
      { 
       // add item 
       $Childrens[$item->Auto] = array($item); 

       // track item reference 
       $ref[$item->Auto] = &$Childrens[$item->Auto]; 
      } 
      else 
      { 
       // index of Childrens array 
       $count = isset($ref[$item->ParentCat]['Childrens']) 
        ? count($ref[$item->ParentCat]['Childrens']) : 0; 

       // parent already there? else move to back 
       if(isset($ref[$item->ParentCat])) 
       { 
        // set item under proper Childrens array item 
        $ref[$item->ParentCat]['Childrens'][] = array($item); 

        // track reference to new item 
        $ref[$item->Auto] = &$ref[$item->ParentCat]['Childrens'][$count]; 
       } 
       else 
       { 
        // if parent isn't there, add to end of array and we'll get to it later 
        array_push($original, $item); 
       } 
      } 
     } 
     return $Childrens; 
    }
