查询前台页面(enword.php)
<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8"></head><body><img src="1.png"/ alt="小词典(php)" ><h1>英汉词典</h1><form action="enw.php" method="post">请输入英文:<input type="text" name="enword" /><input type="submit" value="查询" name="serch" /></form></body></html>
2.编写数据库操作类(ewTool.class.php)
<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8"></head><body><?phpclass enwTool{ protected $conn; private $host="127.0.0.1"; private $user="root"; private $password=""; protected $bd="php_dic"; //构造函数声明变量 public function __construct() { $this->conn=mysql_connect($this->host,$this->user,$this->password) or die("链接失败"); mysql_select_db($this->bd); mysql_query("set names utf8"); } //查询数据库语句 public function dql($sql) { //$res为资源型 $res=mysql_query($sql,$this->conn) or die(mysql_error()); return $res; } //添加数据库语句 public function dml($sql) { $b=mysql_query($sql,$this->conn); if(!$b) { return 0; } else { if(mysql_affected_rows($this->conn)) { return 1; } else { return 2; } } }}?></body></html>
3.编写添加前台页面(add.php)
<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8"></head><body><h1>请添加英汉</h1><form action="dml.php" method="post">请输入英文:<input type="text" name="eng"/>请输入中文:<input type="text" name="chi"><input type="submit" value="添加"></form></body></html>
4.便面dml语句代码。
<html><head><meta http-equiv="Content-Type" content="text/html;charset=utf-8"></head><body><?phprequire_once "enwTool.class.php";$eng=$_REQUEST['eng'];$chi=$_REQUEST['chi'];if(isset($eng)||isset($chi)){ $sql="insert into dic (enword,chword) values ('$eng','$chi')"; $p=new enwTool(); $res=$p->dml($sql); if($res==0) { echo "老兄没有你没有写东西吧!"; } else if($res==1) { echo "恭喜添加成功!"; echo "<a href='enword.php'>返回</a>"; } else if($res==2) { echo "你添加有误!"; }}else{ echo"请输入"; echo"<a herf='add.php'>返回</a>"; }?></body></html>
以上就是php代码啦。
mysql操作也是至关重要的哦!
创建数据库
create database php_dic;
2.创建一张表
create table dic(
dic_id int primary key auto_increment,
enword varchar(20) not null default'',
chword varchar(200) not ull default''
)set character utf8;
3.设置字符集
set names utf8;
4.设置数据库表编码和表编码
alter database php_dic character set utf8;
alter table dic character set utf8;
然后就可以查询和添加啦~~
