Question

我有分页代码。它工作正常。但我添加了搜索功能。所以问题是，当我按下提交按钮时，它显示搜索结果与分页。当我点击页码页面获得刷新并且网格具有所有默认值时，它将丢失搜索名称。

那么如何在整个页面安装过程中阻止搜索名称？如果我使用会话，那么我什么时候可以进入会话以及何时删除会话？

我获取所有产品的代码如下：

     $data = $this->paginate('Product');
     $this->set("Products",$data);

并且条件如下：

   $productname = $this->data['User']['search'];
   $productname = trim($productname);

   $cond = array('Product.productname LIKE' => "%$productname%"); 
   $this->set('Products', $this->paginate("Product", $cond));

我可以解决我的问题吗？感谢

您可以将搜索请求添加到此类

这样的参数中

$this->params['named']['search'] = urlencode(json_encode($productname));

在浏览页面时，产品名称将可用（检查URL，您将看到您的请求）。然后，您可以通过查看params数组来检索所请求的产品。

if (isset($this->params['named']['search'])) {
  $productname = json_decode(urldecode($this->params['named']['search']));
  // ...
}

编辑：示例

// inside the index action

if (isset($this->data['User']['search'])) {
    $productname = $this->data['User']['search'];
    $productname = trim($productname);
    $this->params['named']['search'] = urlencode(json_encode($productname));
}

$cond = array();

if (isset($this->params['named']['search'])) {
    $productname = json_decode(urldecode($this->params['named']['search']));
    $cond = array('Product.productname LIKE' => "%$productname%");
}

$this->set('Products', $this->paginate("Product", $cond));

您可以使用搜索名称添加分页

在您的控制器中

<?php

$separator = array();
$urlSeparator = array();
$search_keyword = '';
$cond = array();

/* if user enter search keyword then  */
if (!empty($this->request->data)) {
 if (isset($this->request->data['User']['Search']) && ($this->request->data['User']['Search'] != '')) {
    $search_keyword = $this->request->data['User']['Search'];
}
}
/*if search keyword is not enter then look for pagination condition params*/
elseif (!empty($this->request->params['named']['cond'])) {

$this->request->params['named']['cond'] = strtr($this->request->params['named']['cond'], '-_, ', '+/=');

$this->request->params['named']['cond'] = json_decode(base64_decode($this->request->params['named']['cond']), true);
    if (isset($this->request->params['named']['cond']['search_keyword']) &&   $this->request->params['named']['cond']['gender'] != '') {
    $search_keyword = trim($this->request->params['named']['cond']['search_keyword']);
 }
}

if(!empty($search_keyword)){
 $cond[] = "Product.productname LIKE '%" . $search_keyword . "'";
 $separator['search_keyword'] = $search_keyword;
}


if (!empty($this->request->params)) {
   if (isset($this->request->params["named"]["page"])) {
    $urlSeparator[] = 'page:' . $this->request->params["named"]["page"];
   }
   if (isset($this->request->params["named"]["sort"])) {
    $urlSeparator[] = 'sort:' . $this->request->params["named"]["sort"];
   }
   if (isset($this->request->params["named"]["direction"])) {
    $urlSeparator[] = 'direction:' . $this->request->params["named"]["direction"];
  }
}

$urlSeparator = implode("/", $urlSeparator);
$this->set('separator', $separator);
$this->set('urlSeparator', $urlSeparator);

$this->set('Products', $this->paginate("Product", $cond));

?>

并在视图文件中添加以下代码。

<?php
$this->Paginator->options(array('update' => '#div_id_for_update',
    'url' => array('controller' => 'controller_name', 'action' => 'index', "cond" => strtr(base64_encode(json_encode($separator)), '+/=', '-_,')),
));
?>

请根据您的控制器名称修改上述代码。
