public function index()
{
$web_list = S('web_index_data');
if(!$web_list){
$web_list = M('web')->where(array('web_show'=>1))->order('web_sort')->select();
if($web_list){
foreach ($web_list as $kb=>$vb){	
$block_list =  M('web_block')->where(array('web_id'=>$vb['web_id']))->order('web_id')->select();
if(is_array($block_list) && !empty($block_list)) {		
foreach ($block_list as $key => $val) {//将变量输出到页面
$val['block_info'] = unserialize($val['block_info']);
$web_list[$kb][$val['var_name']] = $val['block_info'];
}
}
}
S('web_index_data',$web_list);
}
}
$this->assign('web_list', $web_list);
return $this->fetch();
}
