thinkphp写的登录注册的⼩demo
和asp类似，⼀个FormAction对应Form⽂件夹
demo结构：
‘
login.html
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<meta charset="UTF-8">
<FORM method="post" action="__URL__/logFind">//注意action
⽤户名：<INPUT type="text" name="username"><br/>
密码：<INPUT type="password" name="password"><br/>
<INPUT type="submit" value="登录">
</FORM>
</body>
</html>
regist.html
<!DOCTYPE html>
<html lang="en">thinkphp3
<head></head>
<body>
<meta charset="UTF-8">
<FORM method="post" action="__URL__/RegInsert">
⽤户名：<INPUT type="text" name="username"><br/>
密码：<INPUT type="password" name="password"><br/>
<INPUT type="submit" value="注册">
</FORM>
</body>
</html>
FormAction.class.php
class FormAction extends Action{
public function logFind(){
$Form  =  D('Form');
if($Form->create()) {
$username=$this->_post("username");
$password=$this->_post("password");
$User = M("User");
$map['username&password'] =array($username,$password,'_multi'=>true);//多条件查⼀定要加上_multi=>true
$data=$User->where($map)->find();
if($data)
{
echo "登录成功";
}
else
{
$user['username']=$username;
$pasw['password']=$password;
$data=$User->where($user)->find();//⽤username查该⽤户的所有信息
if($data==null)
{
redirect(U("Form/regist"),1,"⽤户名不存在，即将跳转注册");
}
else
{
redirect(U("Form/login"),1,"密码出错，跳转登录");
}
}
}
}
public function RegInsert()
{
$user = D('user');//user->add()时才会添加到user那张表，如果是$form=D('form')，就会添加到form这张表
if($user->create()) {
$result = $user->add();//判断插⼊是否成功
if($result) {
$this->success('操作成功！');            }else{
$this->error('写⼊错误！');
}
}else{
$this->error($Form->getError());        }
}
}
