在 SMARTY 模板中引用数组中的索引

Question

我有一个 Smarty 中的数组变量，我正在尝试找出如何检索该信息。该变量称为 $COMMENTS，我执行了 $COMMENTS|@print_r ，这就是我得到的：

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

            [17] => 6731
        ) 
    )
)

我正在尝试从中检索 11686 数字。有什么帮助吗？我尝试过 $COMMENTS[0][data:private][0] 但没有成功。

非常感谢任何帮助:)

首先，将 print_r() 输出放入

 标记中，以便其可读。

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

您正在尝试访问数组中的第一个对象 $COMMENTS[0]。由于它是对象，并且您的 data 属性是私有的，因此您无法在 Smarty 中访问它。您必须编辑 ModComments_CommentsModel 类才能访问该属性的 data 属性或 crmid 键。

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()}
