Php 变量“沙龙”不存在-（细枝错误）-获取沙龙id

在我的布局中，我想获得由id salon编辑的salon_视图。 以下是symfony2错误变量salon在lign 61上不存在->

你能帮我吗

这是这根树枝的那部分

<ul class="nav navbar-nav navbar-right">
                        <li>
                            {% if is_granted('ROLE_SALON') %}
                                <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
                            {% elseif is_granted('ROLE_USER') %}
                                <a href=# class="link_pink">Mon compte</a>
                            {% endif %}
                        </li>
                    {% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}
                        <li>
                            <a href="{{ path('fos_user_security_logout') }}" class="link_rouge">Se déconnecter</a>
                        </li>
                    {% else %}
                        <li>
                            <a class="link_pink" href="{{ path('user_inscription') }}">S'inscrire</a>
                        </li>
                    {% endif %}
                </ul>

你经过一系列的沙龙，叫做沙龙。如果你想进入，你必须穿过一根树枝做一个循环。因此，在你的报告中：

{% if is_granted('ROLE_SALON') %}
    <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
{% elseif is_granted('ROLE_USER') %}
    <a href=# class="link_pink">Mon compte</a>
{% endif %}

您必须修改为：

{% if is_granted('ROLE_SALON') %}
    {% for salon in salons %}
        <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
    {%endfor%}
{% elseif is_granted('ROLE_USER') %}
    <a href=# class="link_pink">Mon compte</a>
{% endif %}

编辑1：您能否在探查器中提供请求属性部分的内容？如果您试图访问父模板的变量，请尝试此操作，也许可以

{%set salonParentVar=salon%}

你们为沙龙提供了价值吗？类似于控制器中的返回数组“salon”=>$salon。编辑：我的意思是在show controller中不是Edit，因为您显然在Edit中提供了它。是的，在这个lign中，我想从我的SalonBundle\controller\SalonController调用editAction。我以为我是在呼吁采取行动。如何修复它？非常感谢@mikdev。是的，我已经在我的showAction公共函数showActionSalon$salon{$deleteForm=$this->createDeleteForm$salon；return$this->render'@salon/salon/show.html.twig'，array'salon'=>$salon'，delete_form=>$deleteForm->createView，；}您能否更新您的问题并提供showAction？这是我的showAction/***查找并显示沙龙实体。**@Route/{id}，name=salon\u show*@MethodGET*/公共函数showActionSalon$salon{$deleteForm=$this->createDeleteForm$salon；return$this->render'@salon/salon/show.html.twig'，array'salon=>$salon，'delete\u form=>$deleteForm->createView，；}thx发送给@mickdev，他一直在贬低我的优点，而不是搜索回答问题。很抱歉，我不理解您关于“请求属性”部分内容的问题profiler@PierrickMartelli我没有投你的反对票。与其指责，不如先查看我的个人资料。不管怎样，你收到了其他成员的反对票，因为你没有回答问题，而是在发垃圾邮件。我是来帮忙的，得分是我最不担心的事。现在我们能支持帮助别人吗？谢谢。@mickdev不用担心，我告诉他我做到了，主持人在我们升起旗帜后过来了。现在一切都好了：我请求这个来看看他在问什么路线，因为他似乎融合了一些概念

{% if is_granted('ROLE_SALON') %}
    {% for salon in salons %}
        <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
    {%endfor%}
{% elseif is_granted('ROLE_USER') %}
    <a href=# class="link_pink">Mon compte</a>
{% endif %}
