dede织梦程序系统怎样导出网站的后台的文章或自定义模型中的数据到excel,并且不出现乱码

在网站的后台目录创建一个php网站文件toexcel.php,在最上面加入相关具体代码如下;

require_once(dirname(__FILE__).'/config.php');

require_once(DEDEINC.'/typelink.class.php');

require_once(DEDEINC.'/datalistcp.class.php');

require_once(DEDEADMIN.'/inc/inc_list_functions.php');

加入导出到excel类;

class Excel

{    

  private $head;     

private $body; 

  public function addheader($arr){        

  foreach($arr as $headVal){            

$headVal = $this->charset($headVal);             

$this->head .= "{$headVal}\t ";        

}         

$this->head .= "\n";     

} 

  public function addBody($arr){         

  foreach($arr as $arrBody){             

foreach($arrBody as $bodyVal){                 

$bodyVal = $this->charset($bodyVal);                 

$this->body .= "{$bodyVal}\t ";             

}             

$this->body .= "\n";        

}     

} 

  public function downLoad($filename=''){         

  if(!$filename)             

  $filename = date('Ymdhis',time()).'.xls';         

  header("Content-type:application/vnd.ms-excel");         

  header("Content-Disposition:attachment;filename=$filename");          

  header("Content-Type:charset=gb2312");         

  if($this->head)            

  echo $this->head;         

    echo $this->body;     

} 

   public function charset($string){         

return mb_convert_encoding($string,'GBK','auto');    

   } 

}

相关具体代码如下解释:

public function addheader($arr){        

  foreach($arr as $headVal){            

$headVal = $this->charset($headVal);             

$this->head .= "{$headVal}\t ";        

}         

$this->head .= "\n";     

}

2.输出导出网站内容数组,并转码

public function addBody($arr){         

  foreach($arr as $arrBody){             

foreach($arrBody as $bodyVal){                 

$bodyVal = $this->charset($bodyVal);                 

$this->body .= "{$bodyVal}\t ";             

}             

$this->body .= "\n";        

}     

}

3.设置header头部信息和导出到excel网站内容,并输出到浏览器

public function downLoad($filename=''){         

  if(!$filename)             

  $filename = date('Ymdhis',time()).'.xls';         

  header("Content-type:application/vnd.ms-excel");         

  header("Content-Disposition:attachment;filename=$filename");          

  header("Content-Type:charset=gb2312");         

  if($this->head)            

  echo $this->head;         

    echo $this->body;     

}

4.转码,这里不用iconv系统数据库函数,有可能会与gd冲突导致输出空白。用

public function charset($string){         

return mb_convert_encoding($string,'GBK','auto');    

   }

7.具体调用相关具体操作方法;

$excel = new Excel();  

$excel->addheader(array('列一','列二','列三','列四')); 

global $dsql; 

$sql="select 列一字段,列二字段,列三字段,列四字段 from 表名"; 

$dsql->SetQuery($sql);

$dsql->Execute();

while($row = $dsql->GetArray()){

$list[]=$row;

}

unset($row);

$excel->addBody($list);  

$excel->downLoad();

后天添加导出到excel相关具体代码如下:

找到网站的后台目录下的templets目录,下面有个content_list.htm网站文件,

找到<a href="javascript:;" onClick="cAtts('attsDel',event,this)" class="coolbg"> 删除属性 </a>

在后面加一段相关具体代码如下

<?php if($channelid==1) echo " <a href=\"toexcel.php\" class=\"coolbg\" target=\"_blank\">导出到excel</a>\r\n"; ?>

$channelid就是你的模型id,根据你导出的表填写。填写完之后打开网站的后台栏目站点列表就出现导出按钮

注意事项

转码问题,根据自己的实际情况

导出字段,多表或自定义模型的表可以通过left join
