织梦cms GB5.5删除文章时同时删除大图和缩略图？

Answer 1

DEDE系统删除文章同时删除缩略图和大图导读：
打开dede/inc/inc_batchup.php找到"//删除数据库的内容"前面加 //删除缩略图if($arcRow['litpic']!=""){$dsql->ExecuteNoneQuery("Delete From dede_uploads where url='$arcRow[li 打开dede/inc/inc_batchup.php
找到"//删除数据库的内容"
前面加
//删除缩略图
if($arcRow['litpic']!=""){
$dsql->ExecuteNoneQuery("Delete From dede_uploads where url='$arcRow[litpic]'");
$truedir = GetTruePath($arcRow['siterefer'],$arcRow['sitepath']);
$litpicfile = $truedir.$arcRow['litpic'];
@unlink($litpicfile);
}

//删除大图
$arcbodyQuery = "Select * from ".$arcRow['addtable']." where aid='$aid'";
$arcbodyRow = $dsql->GetOne($arcbodyQuery);
$imgsrcarray=GetImageSrc($arcbodyRow['body']);
foreach ($imgsrcarray as $v) {
if((trim($v)!="")&&(!eregi("^http://",$v))){
$dsql->ExecuteNoneQuery("Delete From dede_uploads where url='$v'");
$truedir = GetTruePath($arcRow['siterefer'],$arcRow['sitepath']);
$picfile = $truedir.$v;
@unlink($picfile);
}
}
找到Select a.ID,a.title,a.typeid,改成Select a.ID,a.title,a.typeid,a.litpic,
在页面最后加入函数
//删除文章同时删除大图函数function GetImageSrc($body){
if( !isset($body)) return;
else{
preg_match_all("/<(img|IMG)(.*)(src|SRC)=[\"|'|]{0,}([h|\/].*(jpg|JPG|gif|GIF))[\"|'|\s]{0,}/isU",$body,$out);
return $out[4];
}
}
