有时候我们删除文章的时候,文章的图片还是会留存在你的图片文件夹上面,这样很占服务器的内存,程序也会变得很大,所以我们需要删除文章的同时把文章里的图片、缩略图也对应的删掉。
但织梦本身是不支持的,需要经过二次开发才可以,互联网上有很多方法,本人测过有些虽然能删除文章内的图片,但是并不能删除缩略图;有些虽然可以达到效果,但修改处太多,影响网站的一些功能失效。一、首先在修改前把需要修改的php文件备份好!
二、找到 织梦/include/extend.func.php
复制以下的全部代码直接覆盖到 extend.func.php 里最后
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($fp, "\r\n{$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 $row; else return false; }
三、找到\dede\inc\inc_batchup.php
复制以下的全部代码直接覆盖 到 inc_batchup.php 文件,\dede\为默认的后台目录,如路径已修改,根据自己网站路径找对应的路径。
<?php function DelArc($aid, $type = 'ON', $onlyfile = false) { global $dsql, $cfg_cookie_encode, $cfg_multi_site, $cfg_medias_dir; global $cuserLogin, $cfg_upload_switch, $cfg_delete, $cfg_basedir; global $admin_catalogs, $cfg_admin_channel; if ($cfg_delete == 'N') $type = 'OK'; if (empty($aid)) return; $aid = ereg_replace("[^0-9]", '', $aid); $arctitle = $arcurl = ''; //查询表信息 $query = "Select ch.maintable,ch.addtable,ch.nid,ch.issystem From `dede_arctiny` arc left join `dede_arctype` tp on tp.id=arc.typeid left join `dede_channeltype` ch on ch.id=arc.channel where arc.id='$aid' "; $row = $dsql->GetOne($query); $nid = $row['nid']; $maintable = (trim($row['maintable']) == '' ?
