在SMARTY模板

Question

數組引用索引我有一個變量是Smarty的一個數組，我試圖找出如何獲取這些信息。該變量稱爲$意見，我做了$COMMENTS|@print_r，這是我得到了什麼：

Array ( 
    [0] => ModComments_CommentsModel Object ( 
     [data:private] => Array ( 
      [0] => 11686

      [parent_comments] => 
      [17] => 6731 
     ) 
    ) 
) 

我正在嘗試從該號。任何幫助？我試過$COMMENTS[0][data:private][0]，但沒有奏效。

任何幫助，不勝感激:)

首先，把print_r()輸出到<pre>標記，以便它是可讀的。

Array ( 
    [0] => ModComments_CommentsModel Object ( 
     [data:private] => Array ( 
      [0] => 11686 
      [crmid] => 11686 
      [1] => 1679 
      [smcreatorid] => 1679 
      [2] => 1679 
      ... 
     ) 
    ) 
    ... 
) 

您正試圖訪問陣列中的第一個對象$COMMENTS[0]。既然這是對象，而你的data屬性是私人的，你不能在Smarty中訪問它。您必須編輯ModComments_CommentsModel類，才能訪問屬性的data屬性或crmid鍵。

例子：

class ModComments_CommentsModel { 

    // ... 

    public function CrmId(){ 
     return $this->data['crmid']; 
    } 

    // ... 

} 

---

{* template *} 
{$COMMENTS[0]->CrmId()} 

{* might have to assign before using method call *} 
{assign var='comment' value=$COMMENTS[0]} 
{$comment->CrmId()}
