從樹枝模板中的表格顯示分層數據

我正在使用Symfony2和樹枝：我有一個設置爲使用Doctrine處理分層數據的表格。這是一個類別列表與父 - >兒童 - > sub_children-> sub_sub_children等...許多變化。從樹枝模板中的表格顯示分層數據

我能夠在網頁上顯示它們像這樣，但問題是沒有「缺口」，以顯示其元素屬於哪個父母或子女或子女的孩子等等等等

<table class="table" id="tableList"> 
      <thead> 
      <tr> 
       <th>Category Name</th> 
      </tr> 
      </thead> 
      <tbody> 
      {% for productCategory in productCategories %} 
       <tr> 
        <td>{{ productCategory.name }}</td> 
       </tr> 
      {% endfor %} 
      </tbody> 
     </table>

我倒是像列表看起來是這樣的：

Parent 
     Child 
      Child 
Parent 
     Child 
Parent 
     Child 
      Child 
       Child

，而不是像這樣：

Parent 
Child 
Child 
Child 
Parent 
Child 
Parent 
etc. 
etc.

任何人都知道如何做到這一點？

非常感謝！

你可以發佈'productCategory'的實體結構嗎？需要知道您的父類和子類是如何關聯和訪問的，以幫助代碼遍歷它們。 –

編輯原帖以反映，謝謝。 – LargeTuna

使用無序列表，縮進將更容易，因爲它們會自動由瀏覽器的默認用戶代理樣式表縮進。這應做到：

此方法添加到您的產品分類實體：

public function getChildren() { 
    return $this->children; 
}

，這在樹枝模板

{% for productCategory in productCategories %} 
    {{ _self.display_tree(productCategory) }} 
{% endfor %} 

{% macro display_tree(level) %} 
    <ul> 
     <li>{{ level.name }} 
     {% if level.children|default() %} 
      {% for child in level.children %} 
       {{ _self.display_tree(child) }} 
      {% endfor %} 
     {% endif %} 
     </li> 
    </ul> 
{% endmacro %}

謝謝肯給我一個答案，但我有點問題。我在安裝代碼後收到此錯誤：對象「WIC \ ProductCategoryBundle \ Entity \ ProductCategory」的方法「children」在/ Applications/XAMPP/xamppfiles/htdocs/symfonydev/src/WIC/ProductCategoryBundle/Resources中不存在/views/ProductCategory/list.html.twig第58行 – LargeTuna

哦，我只是看着你的實體，你需要添加一個'getChildren（）'方法。更新我的答案。 –

哦，您可能還需要在'ProductCategory'實體的'__construct（）'中將'children'設置爲'ArrayCollection'，就像您製作產品一樣。 –

只是一點點升級到前面的回答。

<ul> 
{% for productCategory in productCategories %} 
    {{ _self.display_tree(productCategory) }} 
{% endfor %} 
</ul> 

{% macro display_tree(level) %} 
    <li>{{ level.name }} 
    {% if level.children|default() %} 
     <ul> 
     {% for child in level.children %} 
      {{ _self.display_tree(child) }} 
     {% endfor %} 
     </ul> 
    {% endif %} 
    </li> 
{% endmacro %}

這將構建更好看的HTML。
