網站用標簽實現圖片自動Alt功能

第一步，在織夢dedecms網站的根目錄下，打開源代碼文件：Include/ arc.archives.class.php

第二步，在這個文件中查找下面的代碼：     

1. @SetSysEnv($this->Fields['typeid'],$this->Fields['typename'],$this->Fields['id'],$this->Fields['title'],'archives'); 

第三步：把上面這段代碼修改為下面代碼：

1. $this->Fields['body'] = str_ireplace(array('altalt=""','alt=/'/''),'',$this->Fields['body']); 
2. $this->Fields['body'] = preg_replace("@ [/s]{0,}alt[/s]{0,}=[/"'/s]{0,}[/s/S]{0,}[/"'/s] @isU"," ",$this->Fields['body']); 
3. $this->Fields['body'] = str_ireplace("<img " ,"<img alt=/"".$this->Fields['title']."/" ",$this->Fields['body']); 
4. $this->Fields['imgurls'] = str_ireplace(array('altalt=""','alt=/'/''),'',$this->Fields['imgurls']); 
5. $this->Fields['imgurls'] = preg_replace("@ [/s]{0,}alt[/s]{0,}=[/"'/s]{0,}[/s/S]{0,}[/"'/s] @isU"," ",$this->Fields['imgurls']); 
6. $this->Fields['imgurls'] = str_ireplace("<img " ,"<img alt=/"".$this->Fields['title']."/" ",$this->Fields['imgurls']); 

第四步，保存文件刷新
