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);
$excel->downLoad();
后天添加导出到excel代码：
找到后台目录下的templets目录，下面有个content_list.htm文件，
找到<a rel="nofollow noopener noreferrer" href="javascript：;" onClick="cAtts('attsDel',event,this)" class="coolbg"> 删除属性 </a>
在后面加一段代码
<?php if($channelid==1) echo " <a rel="nofollow noopener noreferrer" 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
以上就是dede织梦后台增加php导出到excel功能不出现乱码。有时候，我们必须闭上嘴，放下自己的骄傲，承认是自己错了。这不是认输，而是成长。更多关于dede织梦后台增加php导出到excel功能不出现乱码请关注haodaima.com其它相关文章！
