ThinkPHP user login registration related code cases
1. Modify the module configuration, Application/current module name/Conf/config.php
<?phpreturn array( //数据库配置信息 'DB_TYPE' => 'mysql', // 数据库类型 'DB_HOST' => 'localhost', // 服务器地址 'DB_NAME' => 'thinkphp', // 数据库名 'DB_USER' => 'root', // 用户名 'DB_PWD' => '', // 密码 'DB_PORT' => '', // 端口 'DB_PREFIX' => 'think_', // 数据库表前缀 'DB_CHARSET'=> 'utf8', // 字符集 'DB_DEBUG' => TRUE, // 数据库调试模式 开启后可以记录SQL日志 3.2.3新增);
2. Open Home/Controller/IndexController.class.php and modify the index function.
public function index(){
$this->display();
}3. Open /Home/View/index/index.html, define the login url, and add Form.
<?php $actUrl="\"".U('index/Login',"")."\""; //ThinkPHP内置的U方法，用于URL的动态生成 ?> <form action=<?php echo $actUrl?> method="post"> <p>UserName: <input type="text" name="username" /></p> <p>Password: <input type="text" name="password" /></p> <input type="submit" value="Submit" /> </form>
4. Open Home/Controller/IndexController.class.php and add the login function.
public function Login()
{ $inputname=I('post.username'); //获取Form数据
$inputpwd=I('post.password'); //I方法是ThinkPHP用于更加方便和安全的获取系统输入变量
$User = M('User'); //使用M方法实例化的话，由于不需要加载具体的模型类，所以性能会更高
$condition['username'] = $inputname;
$userinfo=$User->where($condition)->select(); //使用数组作为查询条件
if(0==count($userinfo[0]))
echo "登陆失败，不存在此用户名";
else{
if($inputpwd!=$userinfo[0]['password'])
echo "登陆失败，密码错误！".$userinfo[0]['password'];
else
{
echo "用户名：".I('post.username')."密码：".$userinfo[0]['password'];
}
}
}5. Registering a user means getting the data submitted by the form and adding it to the database table.
public function RegisterInfo()
{
$username=I('post.username');
$password=I('post.password');
$User = M('User');
$data['username'] = $username;
$data['password'] = $password;
$User->add($data);
//ThinkPHP的数据写入操作使用add方法
echo "注册成功";
