下面图片是今天做的前台和后台,前台是套用上星期五的模板.后台是随手写的.

 

今天学习到了

css的 overflow设置内容超过范围就可以给滚动条或者隐藏滚动条

overflow:hidden 就是隐藏咯

php方面又写了一次mysql类.超级简单的


[php]
    /**
    * 用于mysql操作的类
    */ 
    class db_mysql 
    { 
        var $conn; 
 
        function __construct($localhost,$userName,$password,$dbName) 
        { 
            $this->conn=mysql_connect($localhost,$userName,$password); 
 
            mysql_select_db($dbName,$this->conn); 
            mysql_query("set names utf8",$this->conn); 
 
        } 
 
        function __destruct() 
        { 
            mysql_close($this->conn); 
        } 
 
 
        function query($sql) 
        { 
            //echo $sql;  
            return mysql_query($sql,$this->conn); 
 
        } 
 
 
    } 
 ?> 

 /**
 * 用于mysql操作的类
 */
 class db_mysql
 {
  var $conn;

  function __construct($localhost,$userName,$password,$dbName)
  {
   $this->conn=mysql_connect($localhost,$userName,$password);

   mysql_select_db($dbName,$this->conn);
   mysql_query("set names utf8",$this->conn);

  }

  function __destruct()
  {
   mysql_close($this->conn);
  }


  function query($sql)
  {
   //echo $sql;
    return mysql_query($sql,$this->conn);

  }


 }
 ?>

今天遇到纠结的问题,交互动作..本身是想写mvc的单一入口形式,但是这样写代码速度不就慢了,然后我就采取了一直似乎不错的解决方案

1.建立action文件夹,建立 type.php 用于文章栏目操作

2.建立 article.php 用于文章操作,

这样的话 我用ajax发送请求只需"/action/type.php?action=list"搞定.然后做判断什么的执行对应代码.用了 switch语句.


[php]
?php    
    require '../inc.php'; 
 
    switch ($_GET['action']) { 
 
        case 'submit': 
            if(!empty($_POST['typeName'])){ 
             
                $json['state']="no"; 
 
                $bool=$db->query("insert into typename (`name`) value('{$_POST['typeName']}')"); 
                if($bool){ 
                    $json['state']="ok"; 
                }else{ 
                    $json['error']='栏目插入失败'; 
                } 
                echo json_encode($json); 
            } 
 
            break; 
        case 'list': 
                $result = $db->query('select * from typename'); 
                $arr=array(); 
                while($row = mysql_fetch_assoc($result)){ 
                    $arr[]=$row; 
                } 
                echo json_encode($arr); 
            break; 
 
        default: 
            # code... 
            break; 
    } 
 
 
?> 

 require '../inc.php';

 switch ($_GET['action']) {

  case 'submit':
   if(!empty($_POST['typeName'])){
   
    $json['state']="no";

    $bool=$db->query("insert into typename (`name`) value('{$_POST['typeName']}')");
    if($bool){
     $json['state']="ok";
    }else{
     $json['error']='栏目插入失败';
    }
    echo json_encode($json);
   }

   break;
  case 'list':
    $result = $db->query('select * from typename');
    $arr=array();
    while($row = mysql_fetch_assoc($result)){
     $arr[]=$row;
    }
    echo json_encode($arr);
   break;

  default:
   # code...
   break;
 }


?>
