cakephp pagination

当我激活管理路由时，我很难想出如何在cakePHP中分页

我有
localhost/myapp
这是主页 和localhost/myapp/admin，这是管理区域。所以我想在前端分页，在localhost/myapp索引页面中

所以作为主索引页的是类型学模型的索引。 在我的app/Config/routes.php中，我有一个主页的路由：

Router::connect(
  '/', 
     array(
       'admin'=>false,
       'controller' => 'typologies', 
       'action' => 'index', 'index'
    )
);
PS：我也使用slug来查找帖子

在我的应用程序/控制器/类型控制器中，我有以下内容：

$this->Paginator->settings =  array(
    'joins' => array(
        array(
            'table' => 'items',

            'type' => 'LEFT',
            'conditions' => array('Item.id = Typology.item_id')

    ),
        'conditions' => array(
            'Item.published' => 1,

如您所见，首先，我将所有数据存储到一个变量中，然后使用paginator助手像这样回显它：

<?php 
    if (isset($result)) {
         echo $result;
    }    
?>
<p>
<?php
    echo $this->Paginator->counter(array(
    'format' => __('Page{:page} di {:pages}, Showing {:current} records of {:count} in total, starting at {:start}, and finishing at {:end}')
    ));
?>  
</p>
<div class="paging">
<?php
    echo $this->Paginator->prev('< ' . __('Preview'), array(), null, array('class' => 'prev disabled'));
    echo $this->Paginator->numbers(array('separator' => ''));
    echo $this->Paginator->next(__('Next') . ' >', array(), null, array('class' => 'next disabled'));
?>
</div>
所以我第一次加载页面时，URL是这样的
http://localhost/mycakephpApp/
它显示一个日期，就像它假设的那样：

当我单击next（下一步）或数字2时，URL如下所示：
http://localhost/mycakephpApp/typologies/index/index/page:2
，它应该显示下一个。是的，但现在是这样的空白。

我不知道我错过了什么或者我做错了什么。有人知道如何解决这个问题吗？ 我非常感谢您的帮助。

相对URL有问题 该视图包含以下内容：

$result .= "<div class=\"item\" style=\"background-image:url({$typologyThumbnails});\">";
这意味着对于url
http://localhost/mycakephpApp/
请求以下图像url：

http://localhost/mycakephpApp/img/uploads/typology/thumbnails/whatever.jpg

http://localhost/mycakephpApp/typologies/index/index/img/uploads/typology/thumbnails/whatever.jpg
但是，对于url
http://localhost/mycakephpApp/typologies/index/index/page:2
请求以下图像url：

http://localhost/mycakephpApp/img/uploads/typology/thumbnails/whatever.jpg

http://localhost/mycakephpApp/typologies/index/index/img/uploads/typology/thumbnails/whatever.jpg
这是不存在的

有一个非常简单的解决方案：

  • 始终使用绝对URL，即
    /img/uploads/typology/thumbnails/where.jpg
  • 使用助手函数和路由器类，或者至少识别它们的功能
在使用变量之前，可以按要求通过执行以下操作来解决问题：

$typologyThumbnails = Router::url('/' . $typologyThumbnails);
这将输出：

/mycakephpApp/img/uploads/typology/thumbnails/whatever.jpg
使用帮助程序和元素 查看表单的文件：

img/uploads/typology/thumbnails/whatever.jpg

echo "large chunk of html"
很难阅读/维护。相反，视图代码应为，例如：

<?php
foreach ($typologies as $typology) {
    echo $this->element('typology', array('row' => $typology));
}

// pagination links

在路由选项中设置索引参数
'action'=>'index'，'index'
，尝试不使用它，例如：
路由器：：连接（'/'，数组（admin'=>false，'controller'=>'类型'，'action'=>'index'）比很多，这真的很有帮助。
