gleez 下分页功能优化
当一个控制器里的方法只调用了一次分页功能，且在index的方法里，则无需进行以下优化，否则可以根据建议内容优化；
找到/modules/gleez/classes/gleez/pagination.php文件下的url方法；修改内容见红色字体
public function url($page = 1)
{
// Clean the page number
$page = max(1, (int) $page);
// gleez cms pagination
$pager = '/p'. $page;
// No page number in URLs to first page
if ($page === 1 AND ! $this->config['first_page_in_url'])
{
$page = NULL;
$pager = NULL;
}
switch ($this->config['current_page']['source'])
{
case 'query_string':
//return URL::site($this->_route->uri($this->_route_params).
// $this->query(array($this->config['current_page']['key'] => $page)));
//当调用分页功能时，带uri传值时，则在url链接直接增加查询页数；否则显示的url默认指向该控制器的index的方法，后增加查询页数（且url省略index方法名显示）
if($this->_uri){
return URL::site($this->_uri.
$this->query(array($this->config['current_page']['key'] => $page)));
}else{
return URL::site($this->_route->uri($this->_route_params).
$this->query(array($this->config['current_page']['key'] => $page)));
}
case 'route':
return URL::site($this->_route->uri(
array_merge(
$this->_route_params,
array($this->config['current_page']['key'] => $page)
)
). $this->query());
case 'cms':
return URL::site($this->_uri . $pager . $this->query());
}
return '#';
}
在控制器方法里调用分页功能的方法，写法如下：
public function action_select()
{
$this->title = __(‘分页测试’);
$sql_p = “SELECT * FROM products”;
$p_values = DB::query(Database::SELECT,$sql_p)
->execute()
->as_array();
//计算总的查询记录
$count = count($p_values );
//分页
$pagination = Pagination::factory(array(
'items_per_page' =>20,
'total_items' => $count,
'uri' => $this->request->uri(),//优化分页功能后，新增的
));
$current_page = isset($_GET['page'])?$_GET['page']:1;
$sql_p .=" LIMIT ".(($current_page-1)*20).",20";
$p_values = DB::query(Database::SELECT,$sql_p )
->execute()
->as_array();
//加载试图
$view = View::factory('fenye')
->bind("pagination",$pagination)
->bind(“p_values”,$values);
$this->response->body($view);
}
视图文件中，增加分页的显示，如下
<table>
<thead>
<tr>
<th>model</th>
<th>属性</th>
</tr>
</thead>
<tbody>
<?php foreach($values as $key => $value){?>
<tr>
<td></td>
<td></td>
<?php } ?>
</tbody>
</table>
<?php echo $pagination;?>//分页显示
