我需要使用Knp Pagination Bundle直接解决每页动态设置的记录数。
我阅读了这个页面records per page allow user to choose - codeigniter pagination关于动态设置的每页限制，我知道我需要在每个项目中添加一个下拉列表，向服务器发送请求，并在此请求上使用服务器使用参数来设置每页限制在knp分页包上。但我不确切知道如何在服务器上处理这些操作，而且更难以告诉我如何在下拉列表中创建与查询总数相关的项目。
我的控制员：
public function indexAction()
{
$page_title = Util::getFormattedPageTitle("Customers");
$em = $this->get('doctrine.orm.entity_manager');
$dql = "SELECT a FROM CustomersBundle:Customer a WHERE a.enable = 1 ORDER BY a.id";
//$query = $em->createQuery($dql);
//$customers = $query->execute();
$query = $em->createQuery($dql);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$query,
$this->get('request')->query->get('page', 1)/*page number*/,
3/*limit per page*/
);
// parameters to template
return $this->render('CustomersBundle:Default:index.html.twig', array(
'page_title' => $page_title,
'pagination' => $pagination,
'image_path' => CustomersConstants::$customers_image_thumb_path
));
}
我的观看代码是：
{% extends '::base.html.twig' %}
{% block title %}
{{ page_title }}
{% endblock %}
{% block body %}
<h1>
{{ "customers" }}
</h1>
<br />
{% for customer in pagination %}
<a href="{{ customer.url }}" target="_blank">
<div dir="rtl" class="st_simple_box" id="customer{{customer.id}}" >
<table cellpadding="0" cellspacing="0" width="100%">
<tr>
<td style="vertical-align: top; width: 115px;">
{% if customer.imageName is not empty %}
<img class="newsimage" src="{{asset(image_path) ~ customer.imageName}}" alt="No Image/>
{% else %}
<img class="newsimage" src="{{asset('images/vakil_default_small.png') ~ customer.imageName}}" alt="No Image"/>
{% endif %}
</td>
<td style="text-align: center;">
<p><span style="font-family: Tahoma;">{{customer.titleFa}}</span></p>
</td>
<td style="text-align: justify;">
<p><span style="font-family: Tahoma;">{{customer.descriptionFa}}</span></p>
</td>
</tr>
</table>
</div>
</a>
{% endfor %}
<div class="navigation">
<span>
{{ knp_pagination_render(pagination) }}
</span>
<!--Here is my drop down html code-->
</div>
<br />
{% endblock %}

有没有办法在cookie上设置MaxItemPerPage以获得一个集成变量并使用此变量或更改它，同时在twig文件中显示Knp Pagination。
答案是正确的，但是由于我在许多包中使用分页来在我的实体之间进行分页，所以我需要一个整合变量来更改所有这些。我使用你的答案并在Knp Pagination上自定义sliding.html.twig以获得“customized_sliding.html.twig”的代码
<div class="ui small pagination menu">
<div style="clear: both;">
{% if pageCount > 1 %}
<div class="pagination" style="float: right;">
{% if first is defined and current != first %}
<a href="{{ path(route, query|merge({(pageParameterName): first})) }}" class="small icon item">
<i class="small double angle right icon"></i>
</a>
{% endif %}
{% if previous is defined %}
<a href="{{ path(route, query|merge({(pageParameterName): previous})) }}" class="small icon item">
<i class="small angle right icon"></i>
</a>
{% endif %}
{% for page in pagesInRange %}
{% if page != current %}
<a href="{{ path(route, query|merge({(pageParameterName): page})) }}" class="small item">
{{ page }}
</a>
{% else %}
<a class="small active item">
{{ page }}
</a>
{% endif %}
{% endfor %}
{% if next is defined %}
<a href="{{ path(route, query|merge({(pageParameterName): next})) }}" class="small icon item">
<i class="small angle left icon"></i>
</a>
{% endif %}
{% if last is defined and current != last %}
<a href="{{ path(route, query|merge({(pageParameterName): last})) }}" class="small icon item">
<i class="small double angle left icon"></i>
</a>
{% endif %}
</div>
{% endif %}
<div style="float: left;">
<select name="maxItemPerPage" id="maxItemPerPage">
<option selected="true" style="display:none;">Number Per Page</option>
<option id="10">5</option>
<option id="20">10</option>
<option id="30">20</option>
</select>
</div>
</div>
<script type="text/javascript">
//on select change, you navigate to indexAction and send the parameter maxItemPerPage
$('#maxItemPerPage').change(function(){
{% set currentPath = path(app.request.attributes.get('_route')) %}
var url = "{{path(app.request.attributes.get('_route'),{'maxItemPerPage': '_itemNum'})}}";
var item = $('#maxItemPerPage').find(":selected").text();
jQuery(location).attr('href', url.replace('_itemNum',item ));
});
</script>
</div>
我想从cookie中获取并存储MaxItemPerPage，因此无需更改所有包代码。 例如，在我的控制器中，我不知道必须从cookie
获取$ maxItemPerPage$pagination = $paginator->paginate(
$query,
$this->get('request')->query->get('page', 1)/*page number*/,
$maxItemPerPage/*limit per page*/
);
我需要通过javascript更改html标记的值来更改cookie上maxItemPerPage的值，并将页面重定向到同一个控制器，而不需要将maxItemPerPage发送到控制器。
答案 0 :(得分：2)
这可以轻松完成（如果我理解的话）
public function indexAction($maxItemPerPage=20)
{
$page_title = Util::getFormattedPageTitle("Customers");
$em = $this->get('doctrine.orm.entity_manager');
$dql = "SELECT a FROM CustomersBundle:Customer a WHERE a.enable = 1 ORDER BY a.id";
//$query = $em->createQuery($dql);
//$customers = $query->execute();
$query = $em->createQuery($dql);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$query,
$this->get('request')->query->get('page', 1)/*page number*/,
$maxItemPerPage /*limit per page*/
);
// parameters to template
return $this->render('CustomersBundle:Default:index.html.twig', array(
'page_title' => $page_title,
'pagination' => $pagination,
'image_path' => CustomersConstants::$customers_image_thumb_path
));
}
{% extends '::base.html.twig' %}
{% block title %}
{{ page_title }}
{% endblock %}
{% block javascript%}
<script type="text/javascript">
//on select change, you navigate to indexAction and send the parameter maxItemPerPage
$('#maxItemPerPage').change(function(){
var url = '{{path('controller_index_route','maxItemPerPage':_itemNum)}}';
var item = $('#maxItemPerPage').find(":selected").text();
window.location.href = url.replace('_itemNum',item );
})
</script>
