dedecms删除文章同时也删除附件的修改方法

dedecms删除文章同时也删除附件的修改方法,使用dedecms的朋友可以参考下。

首先添加两个函数 

代码如下:

/* 
根据文档id获取文档的body部分 
*/ 
function getArcBody($arcid) 
{ 
global $dsql; 
if(empty($arcid)) return ; 
$body = ''; 
$query = "select arc.*,ch.addtable,ch.fieldset from `dede_arctiny` as arc left join `dede_channeltype` as ch on arc.channel=ch.id where arc.id=$arcid"; 
$row = $dsql->GetOne($query); 
if(empty($row)) return ; 
$addtable = $row['addtable']; 
$fieldset = $row['fieldset']; 
include_once(DEDEINC.'./dedetag.class.php'); 
$dtp = new DedeTagParse(); 
$dtp->SetNameSpace(&#39;field&#39;,&#39;<&#39;,&#39;>&#39;); 
$dtp->LoadSource($fieldset); 
if(is_array($dtp->CTags)) 
{ 
foreach($dtp->CTags as $tid=>$tag) 
{ 
if($tag->GetAtt(&#39;type&#39;)==&#39;htmltext&#39;) 
{ 
$body = $tag->GetName(); 
break; 
} 
} 
} 
if(!empty($body)) 
{ 
$query = "select $body from `$addtable` where aid=$arcid"; 
$row = $dsql->GetOne($query); 
$body = $row[$body]; 
return $body; 
} 
return ; 
} 
/* 
解析文档内容的本地图片图片 
*/ 
function get_img_from_body($body) 
{ 
$result = array(); 
if(empty($body)) 
return $result; 
preg_match_all(&#39;/\ssrc=([\"|\&#39;])([^\1]*?)\.(gif|jpg|jpeg|png)\1/&#39;,$body,$res); 
if(!empty($res[2])) 
{ 
foreach($res[2] as $k=>$v) 
{ 
$result[] = $v.&#39;.&#39;.$res[3][$k]; 
} 
} 
return $result; 
}

把这段代码贴到include/common.func.php后面, 

接着打开后台(假设使用默认的dede作为后台)dede/inc/inc_batchup.php文件, 

在第22行添加代码如下: 

$body = getArcBody($aid);

接在在第139行,就是在 

return true;

上面一行加上下面的代码 

代码如下:

if($body) 
{ 
$img_arr = get_img_from_body($body); 
if(!empty($img_arr)) 
{ 
foreach($img_arr as $v) 
{ 
$img_file = GetTruePath().str_replace($GLOBALS[&#39;cfg_basehost&#39;],&#39;&#39;,$v); 
if(file_exists($img_file) && !is_dir($img_file)) 
@unlink($img_file); 
} 
} 
}

这样就可以实现删除文档的时候删除字段为“htmltext”类型的中的本地图片了。
