dedecms 5.6 删除文章同时删除图片的方法
最新dedecms5.6删除文章对应删除图片
本代码没改dede代码!只加了删除方法到里面!覆盖就可以了!覆盖时备份好文件!
您也可以看着对应修改!学习一下!
在dede5.6gbk版测试成功!utf8大家自己测试 !覆盖前备份好文件
/include/extend.func.php

代码如下:
<?php
function GetPicsTruePath($body,$litpic) //解析body数据,获得所有图片的绝对地址
{
$delfiles = array();//存储图片地址数据
if(!empty($litpic))
{
$litpicpath = GetTruePath();
$litpicpath .= $litpic;
$delfiles[] = $litpicpath;//缩略图地址
}
preg_match_all("/src=[\"|'|\S|\s]([^ |\/|>]*){0,}(([^>]*)\.(gif|jpg|png))/isU",$body,$tmpdata);
$picspath = array_unique($tmpdata[2]);//body中所有图片的地址
foreach($picspath as $tmppath)
{
$path = GetTruePath();//获得绝对路径
$picpath = preg_replace("/[a-zA-z]+:\/\/[^ |\/|\s]*/",'',$tmppath);//去掉网址部分
$path .=$picpath;
$delfiles[] = $path;//保存处理后的数据
}
return $delfiles;
}
function WriteToDelFiles($msg)//删除文章的时候会通过此函数记录日志
{
if(empty($msg)) $savemsg="未获得消息";
else $savemsg = $msg;
$errorFile = dirname(__FILE__).'/../data/del_body_file.txt';//删除记录文件
$fp = @fopen($errorFile, 'a');
@fwrite($fp,"\r {$savemsg}");
@fclose($fp);
}
//获得文章Body数据
function GetArcBody($aid)
{
global $dsql;
$query = "SELECT dede_addonarticle.body FROM dede_addonarticle WHERE dede_addonarticle.aid = '$aid'";
$row = $dsql->GetOne($query);
if(is_array($row)) return $row;
else return false;
}
function litimgurls($imgid=0){
global $lit_imglist;
$dsql = new DedeSql(false);
//获取附加表
$row = $dsql->GetOne("SELECT c.addtable FROM dede_archives AS a LEFT JOIN dede_channeltype AS c ON a.channel=c.id where a.id='$imgid'");
$addtable = trim($row['addtable']);
//获取图片附加表imgurls字段内容进行处理
$row = $dsql->GetOne("Select imgurls From `$addtable` where aid='$imgid'");
//调用inc_channel_unit.php中ChannelUnit类
$ChannelUnit = new ChannelUnit(2,$imgid);
//调用ChannelUnit类中GetlitImgLinks方法处理缩略图
$lit_imglist = $ChannelUnit->GetlitImgLinks($row['imgurls']);
//返回结果
