dede织梦后台增加导出内容到excel功能方法 不会乱码

dede织梦系统怎样导出后台的文章或自定义模型中的数据到excel,并且不出现乱码

在后台目录创建一个php文件toexcel.php,在最上面加入代码;

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');       } } 

代码解释:

1.输出列名数组,并转码

public function addHeader($arr){          foreach($arr as $headVal){            $headVal = $this->charset($headVal);             $this->head .= "{$headVal}/t ";        }         $this->head .= "/n";     } 

2.输出导出内容数组,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.调用方法;

$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代码:

找到后台目录下的templets目录,下面有个content_list.htm文件,

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

在后面加一段代码

<?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。填写完之后打开后台栏目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
