Question

yii中如何创建一个表单接受数据,并存到数据库中？

Answer 1

1. 确保数据是用户输入安全的（safe）
使用rules方法批量设置Model属性为输入安全的

[php] view plaincopy
public function rules() {
return array(
array('username, password, gender,
email, tel', 'safe'),
);
}

2. 如果设置了场景（Scenario），确保该场景匹配输入安全的规则

[php] view plaincopy
public function rules() {
......
array('gender, email, tel', 'safe', 'on'=> 'create,update'),
......
}
在属性设置前设置一下场景（Scenario），

[php] view plaincopy
...
$model->setScenario('create');
$model->attributes = $_POST['user'];
...

Answer 2

controller方法

public function actionToAddTalk(){
$this->redirect('talk/index');
}

public function actionAddTalk2(){
$talk=new Talk;
$username=$_POST['username'];
$subject=$_POST['subject'];
$content=$_POST['content'];
$talk->subject=$subject;
$talk->username=$username;
$talk->content=$content;
$talk->save();
return $this->actionGetTalk();
}
执行完AddTalk将数据保存在数据库后跳转GetTalk方法
public function actionGetTalk(){//查找所有数据
$talk = Talk::model()->findAll(); //将数据表中全部信息存到 $talk
$this->renderPartial('admin',array('talk'=>$talk));
}
GetTalk将数据库保存的数据传给变量talk，将talk传给admin视图，在视图遍历输出我们提交的数据
