实现dedecms自动给文章图片加alt标签

不废话，直接开始：第一步：打开 include/ arc.archives.class.php , 找到如下代码：

@SetSysEnv($this->Fields[ ypeid],$this->Fields[ ypename],$this->Fields[id],$this->Fields[ itle],archives);

替换为：

$this->Fields[ody] = str_ireplace(array(altalt="",alt=\\\),\,$this->Fields[ody]); $this->Fields[ody] = preg_replace("@ [\s]{0,}alt[\s]{0,}=[\"\s]{0,}[\s\S]{0,}[\"\s] @isU"," ",$this->Fields[ody]); $this->Fields[ody] = str_ireplace("Fields[ itle]."\" ",$this->Fields[ody]); $this->Fields[imgurls] = str_ireplace(array(altalt="",alt=\\\),\,$this->Fields[imgurls]); $this->Fields[imgurls] = preg_replace("@ [\s]{0,}alt[\s]{0,}=[\"\s]{0,}[\s\S]{0,}[\"\s] @isU"," ",$this->Fields[imgurls]); $this->Fields[imgurls] = str_ireplace("Fields[ itle]."\" ",$this->Fields[imgurls]);

第二步骤：没有了！搞定，收工！注意，这个功能是对于生成html页面时起作用,也就是实现一个在生成时的替换功能。
