/macros/subdepartments.html

{% macro displayChildren(departments, parent_id, deep, prefix) %}
    {% import _self as macros %}
    {% for dept in departments %}
        {% if dept.parent_id == parent_id %}
            {% set href = dept.seo_title ~ '/' ~ prefix %}
            <li><a href="/{{ href }}/{{ dept.id }}/dept" class="black" style="margin-left: {{ deep * 10 }}px;">{{ dept.title }}</a></li>
            {{ macros.displayChildren(departments, dept.id, deep + 1, href) }}
        {% endif %}
    {% endfor %}
{% endmacro %}

common.html

<div class="departments">       
                <ul class="nav">
                    <div class="clearfix">                              
                        {% import '/macros/subdepartments.html' as macros %}    
                        {% for dept in common.departments %}
                            {% if dept.parent_id == 0 %}
                                <li><a href="/{{ dept.seo_title }}/{{ dept.id }}/dept" class="black">{{ dept.title }}</a><div class="dropdown-menu"><ol class="nav">{{ macros.displayChildren(common.departments, dept.id, 0, dept.seo_title) }}</ol></div></li>
                            {% endif %}
                        {% endfor %}
                    </div>                  
                </ul>
            </div>

department.html（由Twig的common.html扩展）

<ol class="nav" style="margin-left: 10px;">
        {% for dept in common.departments %}
            {% if dept.id == selected_dept.parent_id %}
                <li><a href="/{{ dept.seo_title }}/{{ dept.id }}/dept" class="black">← {{ dept.title }}</a></li>
            {% endif %}
            {% if dept.parent_id != 0 or dept.id == selected_dept.id %}
                {% if dept.parent_id == selected_dept.parent_id %}
                    <li><a href="/{{ dept.seo_title }}/{{ dept.id }}/dept" class="black{% if dept.id == selected_dept.id %} selected{% endif %}">{{ dept.title }}</a></li>
                    {{ macros.displayChildren(common.departments, dept.id, 1) }}    
                {% endif %}
            {% endif %}
        {% endfor %}</ol>

common.departments数组

在common.html一切都好。在deparment.html中，我需要在{{dept.seo_title}}中获得相同的href。如果我从department.html的common.html转到/tir/ oils / oils / 13 / dept，我会看到错误的部门网址。

← Трансмиссионные масла (href: /transmission-oils/2/dept right!)
для МКПП (механика) (href: mt/11/dept wrong!, need to be /mt/transmission-oils/11/dept)
для АКПП (автомат) (href: at/12/dept wrong!, need to be /at/transmission-oils/12/dept)
Test (href: /test//13/dept wrong!, need to be /test/at/transmission-oils/13/dept)

那么，如何更改department.html中的代码以打印子部门的完整路径？也许递归函数将获得所有父部门。

Answer 1

据我了解，你错过了hrefs中的父路径。

我认为你说的时候会出现问题：

Subdept1_2_1 (link: subdept1_2_1-subdept1_2-subdept1-dept1)

难道你不是指上升顺序的树，例如：

Subdept1_2_1 (link: dept1-subdept1-subdept1_2-subdept1_2_1)

无论如何，你可以试试这样的代码：

main.twig

{% import 'macros.twig' as macros %}    
{% for dept in departments %}
  {% if dept.parent_id == 0 %}
  <li><a href="/{{ dept.seo_title }}/{{ dept.id }}/dept" class="black">{{ dept.title }}</a>
    <div class="dropdown-menu">
      <ol class="nav">{{ macros.displayChildren(departments, dept.id, 0, dept.title) }}</ol>
    </div>
  </li>
  {% endif %}
{% endfor %}

macros.twig

{% macro displayChildren(departments, parent_id, deep, prefix) %}
    {% for dept in departments %}
        {% if dept.parent_id == parent_id %}
            {% set href = prefix ~ '-' ~ dept.seo_title %}
            <li><a href="/{{ href }}/{{ dept.id }}/dept" class="black" style="margin-left: {{ deep * 10 }}px;">{{ dept.title }}</a></li>
            {{ _self.displayChildren(departments, dept.id, deep + 1, href) }}
        {% endif %}
    {% endfor %}
{% endmacro %}

注意：要使用节点的反向路径，请使用：

{% set href = dept.seo_title ~ '-' ~ prefix %}

而不是：

{% set href = prefix ~ '-' ~ dept.seo_title %}

注意：我更改了文件名以获得更好的重现性。

在Twig模板引擎上的菜单中保存完整的URL路径
