1.我的留言板上写上了 add方法


[php]  function add(){ 
    //添加后返回 影响条数,如果大于0就说明添加成功  
    if($this->db->data($_POST)->add()>0){ 
        echo "添加成功"; 
        //  echo "<script>location.reload()</script>";//防止刷新后的表单的重复提交  
        Header("HTTP/1.1 303 See Other"); 
        Header("Location: ");   //转向到根目录  
        exit; 
         
    }else { 
        die($this->db->error());//添加失败输出错误信息  
    }    
} 

  function add(){
   //添加后返回 影响条数,如果大于0就说明添加成功
   if($this->db->data($_POST)->add()>0){
    echo "添加成功";
    // echo "<script>location.reload()</script>";//防止刷新后的表单的重复提交
    Header("HTTP/1.1 303 See Other");
    Header("Location: ");   //转向到根目录
    exit;
    
   }else {
    die($this->db->error());//添加失败输出错误信息
   } 
  }对应提交表单
