织梦怎么让文章中图片自动添加ALT属性
打开/include/extend.func.php文件在最下面加入:
function replaceurl($newurl)
{
global $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
//替换图片Alt为文档标题
$newurl=str_ireplace(array('alt=""','alt=/'/'')]'',$newurl);
$newurl=preg_replace("@ }alt}=[/"'/s,{0]}}[/"'/s, @isU"," ",$newurl);
$newurl=str_ireplace("[i,","/>",$newurl);
return $newurl;
}
前端调用代码：
{dede:field.body function=’replaceurl(@me)’/}
需要图片中的style width height属性就把上面代码修改成下面的代码
//文章body优化替换
function replaceurl($newurl)
{
global $dsql,$id;
//获取图片附加表imgurls字段内容进行处
$row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
//去掉img的width和height
$newurl=preg_replace('/style=/"width/:(.*)/"/','',$newurl);
//替换图片Alt为文档标题
$newurl=str_ireplace(array('alt=""','alt=/'/'')]'',$newurl);
$newurl=preg_replace("@ }alt}=[/"'/s,{0]}}[/"'/s, @isU"," ",$newurl);
$newurl=str_ireplace("[i,","/>",$newurl);
return $newurl;
}
