杜鹃啼血染花红,山后山前一画中。旅行的意义不在于浏览风景,而是到一个完全陌生的环境,放空自己,感受享受孤独!
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 = $dsql->GetOne("SELECT title FROM dede_archives where id=$id"); //替换图片Alt为文档标题 $newurl=str_ireplace(array('alt=""",'alt=/'/''),'',$newurl); $newurl=preg_replace("@ [/s]{0,}alt[/s]{0,}=[/"'/s]{0,}[/s/S]{0,}[/"'/s] @isU"," ",$newurl); $newurl=str_ireplace("<img " ,"<img alt=/"".$row['title']."/"",$newurl); //去掉结尾空格 $newurl=str_ireplace(" /","/",$newurl); $newurl=str_ireplace(" />","/>",$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); $newurl=preg_replace("@ [/s]{0,}alt[/s]{0,}=[/"'/s]{0,}[/s/S]{0,}[/"'/s] @isU"," ",$newurl); $newurl=str_ireplace("<img " ,"<img alt=/"".$row['title']."/"",$newurl); //去掉结尾空格 $newurl=str_ireplace(" /","/",$newurl); $newurl=str_ireplace(" />","/>",$newurl); return $newurl; }
本文织梦怎么让文章中图片自动添加ALT属性到此结束。一生中你唯一需要回头的时候,是为了看自己到底走了多远。小编再次感谢大家对我们的支持!
