我想检索表单（method="get"）发送的参数并将它们添加到路由中。

这是路线：

frontend_list:
path:     /travels/{page}
defaults: { _controller: ProjectFrontendBundle:Frontend:list, page: 1 }

这是形式：

          <form action="" method="get" class="form_sort" id="myForm">
             <span class="manage_title">Sort by:</span>
                <select class="select_styled white_select" id="sort_list" name="sort" onChange="sendForm();">
                        <option value="">-------</option>
                        <option value="country:asc">Country A-Z</option>
                        <option value="country:desc">Country Z-A</option>
                        <option value="destination:asc">City A-Z</option>
                        <option value="destination:desc">City Z-A</option>
                 </select>
           </form>

这是控制器：

    public function listAction($page, Request $request)
{
    $em = $this->getDoctrine()->getManager();
    $nbByPage = $this->container->getParameter('travel.number_by_page');
    if ($request->getMethod() == 'POST')
    {
        $sort = $request->query->get('sort');
        list($orderBy, $orderWay) = explode(":", $sort); //explode 
        $listTravels = $em->getRepository('ProjectTravelBundle:Travel')->getListTravelsFrontend($nbByPage, $page, $orderBy, $orderWay);
        return $this->render('ProjectFrontendBundle:Frontend:list.html.twig',array(
            'listTravels' => $listTravels,
            'page'     => $page,
            'nb_page'  => ceil(count($listTravels) / $nbByPage) ?: 1
        ));
    }
    $orderBy = "id"; // set default orderBy
    $orderWay = "desc"; // set default orderWay
    $listTravels = $em->getRepository('ProjectTravelBundle:Travel')->getListTravelsFrontend($nbByPage, $page, $orderBy, $orderWay);
    return $this->render('ProjectFrontendBundle:Frontend:list.html.twig',array(
        'listTravels' => $listTravels,
        'page'     => $page,
        'nb_page'  => ceil(count($listTravels) / $nbByPage) ?: 1
    ));
}

所以我想有这样的网址，例如在选择选项"排序"时：

localhost/agence/web/app_dev.php/travels?orderby=country&orderway=aesc

现在，当我选择一个选项时，我得到一个这样的非功能性网址：

localhost/agence/web/app_dev.php/voyages?sort=country%3Aasc

所以我的问题是如何在路由frontend_list中添加这些参数，并将它们添加到参数页面旁边的树枝视图中的路径中，以获得带有分页的正确 URL：

                        {% if nb_page > 1 %}
                            {% if  page == 1 %}
                        <a class="link_prev">Previous</a>
                            {% else %}
                        <a href="{{ path('frontend_list', {'page': page - 1}) }}" class="link_prev">Previous</a>
                            {% endif %}
                            {% if  page == nb_page %}
                        <a class="link_next">Next</a>
                            {% else %}
                        <a href="{{ path('frontend_list', {'page': page + 1}) }}" class="link_next">Next</a>
                            {% endif %}
                        {% endif %}

这不是

创建可排序列表的好方法，而不是在symfony中。

我建议你看看KnpPaginatorBundle - SEO友好的Symfony2分页器来排序和分页。

但是，如果您需要使用上面编写的代码。我建议你做第二个选择，分开选择ASC/DESC。

我认为这是可能的，在安装捆绑包之后，您必须在第一个模板"KnpPaginatorBundle：Pagination：sortable_link.html.twig"中覆盖。由于默认模板是用于链接，因此您应该为选择选项创建一个新模板。为此，请在项目结构中创建"app/Resources/KnpPaginatorBundle/views/Pagination/sortable_option.html.twig"

<option {% for attr, value in options %} {{ attr }}="{{ value }}"{% endfor %}>{{ title }}</option>

现在，您的代码将需要进行一些小的修改：

<form action="" method="get" class="form_sort" id="myForm">
    <span class="manage_title">Sort by:</span>
        <select class="select_styled white_select" id="sort_list" name="sort" onChange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
            {{ knp_pagination_sortable(pagination, 'Country', 'object.countryProperty', {'direction': 'asc'}) }}
            {{ knp_pagination_sortable(pagination, 'Country', 'object.countryProperty', {'direction': 'desc'}) }}
            {{ knp_pagination_sortable(pagination, 'City', 'object.cityProperty', {'direction': 'asc'}) }}
            {{ knp_pagination_sortable(pagination, 'City', 'object.cityProperty', {'direction': 'desc'}) }}
        </select>
</form>

编辑：

当然，您必须更改配置文件中的路径

knp_paginator:
    page_range: 5                      # default page range used in pagination control
    default_options:
        page_name: page                # page query parameter name
        sort_field_name: sort          # sort field query parameter name
        sort_direction_name: direction # sort direction query parameter name
        distinct: true                 # ensure distinct results, useful when ORM queries are using GROUP BY statements
    template:
        pagination: KnpPaginatorBundle:Pagination:sliding.html.twig     # sliding pagination controls template
        sortable: KnpPaginatorBundle:Pagination:sortable_option.html.twig # sort option template
        #sortable: KnpPaginatorBundle:Pagination:sortable_link.html.twig # sort link template (default)

Symfony2，向表单发送的路由添加其他参数

Symfony2, add additional parameters to the route sent by the form
