企业想要扩大本人的电商业务，开发一款好的电商零碎必不可少。电商商城网站就是不错的抉择，上面就来分享一下网站的代码。

代码局部

namespace app\home\controller; use think\Page;use think\Verify;use think\Db;use think\Image;class Index extends Base{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) {// 将变量输入到页面
$val['block_info'] = unserialize($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();}

布告详情页

public function notice()    {return $this->fetch();
}
public function qr_code_raw()    {ob_end_clean();
