打开/include/extend.func.php文件

在最下面加入:

//文章body优化替换

function replaceurl($newurl)
{
global $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOG b Q + i E X H %ne("SELECT title FROM dede_archives where id=$y @ 6 A * .id")k Z S _ A Z;
//替换图片Alt为文档d @ I \ a Q { t ^标题
$newurl=str_ireplace(array('alt=""','{ q t e C ? f q nalt=/'/''),'',$newurl);
$newurl=preg_replace("@ [/s]{0,}alt[/s]{0,}=[/"'/s]{0,$ B | V \ *}[/s/S]{0,}[/"'/s] @isU"," ",$newurl);
$6 ^ M _newurl=str_ir! b 7 \ ] , a K 6eplace("<img "w _ t n ,"<img  alt=/"".$row['title']."/"",$newurl);
//去掉结$ ^ - w = c R 5 ,尾空格
$newurl=str_ireplac, j 0 Q ? | Ue(" /","/",$n2 z ~ j &ewurl);
$newurl=str_ireplace(" />","/>",$newurl);
retu= s E Prn $newurl;
}

前端调用代码：

{dede:field.body fuE v H E b V ` ! Cnction=’replaceurl(@me)’/}

需要图片中的style width heiU * ( L * i ^ 8 Bght属性就把上面代码修改{ V a h M \ A成下面的代码

/& q I Z & y E ^/文章body优化替换
function replaceurl($newK L 3url)
{
glL i v /obal $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOne("SE% & P )LECT title FROM dede_archives where id=$id");
//去掉img的width和heP I = u qight
$newurl=preg_replaceJ 8 N z @ 4 V('/style=/"width/:(.*)/"r 2 [ u +/','',X ( O o$ned h 5 \ - D e T \wurl);
