Php Smarty嵌套foreach循环问题

我无法在smarty模板文件中正确显示以下数组。如果有人能帮我指出正确的方向，我将非常感激

            )

        [172] => Array
            (
                [id] => 172
                [title] => Accessories
                [productCount] => 1
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 1
                    )

            )

    )

[72] => Array
    (
        [title] => Men
        [id] => 72
        [productCount] => 2
        [171] => Array
            (
                [id] => 171
                [title] => Footwear
                [productCount] => 2
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 2
                    )

            )

    )

我的模板代码如下所示：

          {foreach from=$trackingGroups item=gender key=k item=v}
          {assign var=tc value="`$v.id`"}    
          {$v.title} ({$v.productCount})<br />

          Women (3)<br />
           W<br />
                    7<br />
                    3<br />
                    Footwear<br />
                    Accessories<br />

          Men (2)<br />
           M<br />
                    7<br />
                    2<br />
                    Footwear<br />




Array

            )

        [172] => Array
            (
                [id] => 172
                [title] => Accessories
                [productCount] => 1
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 1
                    )

            )

    )

[72] => Array
    (
        [title] => Men
        [id] => 72
        [productCount] => 2
        [171] => Array
            (
                [id] => 171
                [title] => Footwear
                [productCount] => 2
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 2
                    )

            )

    )

)当你在第二个foreach中循环时，你是在循环所有元素，而不仅仅是

标题

键。例如：

            )

        [172] => Array
            (
                [id] => 172
                [title] => Accessories
                [productCount] => 1
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 1
                    )

            )

    )

[72] => Array
    (
        [title] => Men
        [id] => 72
        [productCount] => 2
        [171] => Array
            (
                [id] => 171
                [title] => Footwear
                [productCount] => 2
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 2
                    )

            )

    )

{foreach item=department from=$trackingGroups.72 item=v2} 
   {$v2.title}
{/foreach}

在这种情况下，$v2将采用以下值：

            )

        [172] => Array
            (
                [id] => 172
                [title] => Accessories
                [productCount] => 1
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 1
                    )

            )

    )

[72] => Array
    (
        [title] => Men
        [id] => 72
        [productCount] => 2
        [171] => Array
            (
                [id] => 171
                [title] => Footwear
                [productCount] => 2
                [74] => Array
                    (
                        [id] => 74
                        [title] => Boots
                        [productCount] => 2
                    )

            )

    )

[title] => Men
[id] => 72 
[productCount] => 2 
[171] => Array 
 ( 
                [id] => 171 
                [title] => Footwear 
                [productCount] => 2 
                [74] => Array 
                    ( 
                        [id] => 74 
                        [title] => Boots 
                        [productCount] => 2 
                    ) 

 ) 

第一个、第二个和第三个值将只是一个字符串。由于它不是数组，$v2.title将返回“title”的第四个元素（第一个元素），返回第一个字符：M，7,2

---

第四个元素是一个带有“title”键的数组，它被正确返回：shoots。

能否正确标记第一个代码块。目前很难跟上。
