一、新建數據庫(db_movie1-t_movie)
二.連接數據庫
目錄(protected-config-main.php)
//本地的數據庫
'db'=>array(
'connectionString' => 'mysql:host=localhost;dbname=db_movie1', //mysql:host=125.222.222.73 本地數據庫
'emulatePrepare' => true,
'username' => 'root',
'password' => 'mysql',
'charset' => 'utf8',
'tablePrefix' =>'t_',
),
記得修改本地數據庫代碼-（數據庫名+用戶名+密碼）
三、定義 AR 類(創建model)
Active Record (AR) 是一種面向對象風格的,用於抽象數據庫訪問的設計模式.
要訪問一個數據表，我們首先需要通過集成 CActiveRecord 定義一個 AR 類。
每個 AR 類代表一個單獨的數據表，一個 AR 實例則代表那個表中的一行。
在models下新建Movie.php並繼承CActiveRecord
<?php
/**
* Created by PhpStorm.
* User: DELL
* Date: 2018/8/1
* Time: 18:00
*/
class Movie extends CActiveRecord
{
public static function model($className=__CLASS__)
{
return parent::model($className);
}
public function tableName()
{
return 't_movie'; //return '{{movie}}'
}
}
tableName的方法記得要重寫，有兩種寫法
四、控制器（Controller）
新建Movie的文件夾，在裏面新建MovieController.php的文件
class NewsController extends Controller{
}
五、增刪改查方法
列出所有信息
public function actionGetMovie(){
$list = Movie::model()->findAll(); //將t_movie表中全部信息存到 $list中
$this->smarty->assign('list',$list);
$this->smarty->display('movie/listAll.html');//跳到對應的html頁面，內容展示
}
對應的HTML文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table border="1" style="margin-top: 10px;font-size: x-large">
<thead> <tr> <th>電影</th>
<th>內容</th> </tr>
<tr>
</thead> <tbody> <{foreach from=$list item=movie}>
<td><{$movie.name}></td><td><{$movie.director}></td> <td>
<a href="/movie/Movie/GetDeleteMovie?id=<{$movie.id}>">刪除</a>
<a href="/movie/Movie/GetMovieById?id=<{$movie.id}>">查看詳情</a>
<a href="/movie/movie/ToUpdateMovie?id=<{$movie.id}>">修改</a>
<a href="/movie/Movie/ToAddMovie">添加</a>
</td> </tr> <{/foreach}> <tr> <td colspan="2" style="text-align: center" > </td> </tr> </tbody>
</table>
<form name="form" action="/movie/Movie/search" method="post">
<input type="text"style="width: 300px;height: 40px;border-radius:5px;border:1px;" name="keywords" placeholder="請輸入您想查找的內容" autocomplete="off">
<input type="submit" value="搜索">
</form>
</body>
</html>
頁面展示如下
增加
/**
* 跳轉到增加電影頁面
*/
public function actionToAddMovie(){
$this->smarty->display('movie/add.html');
}
/**
* 增加電影
*/
public function actionAddMovie2(){
$movie=new Movie;
$content=$_POST['content'];
$name=$_POST['name'];
$director=$_POST['director'];
$movie->name=$name;
$movie->content=$content;
$movie->director=$director;
$movie->save();
$this->redirect(array(getMovie));
}
HTML增加頁面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/movie/Movie/addMovie2" method="post">
<table style="margin-top: 10px;font-size: x-large" >
<tr>
<td>電影：</td>
<td><input type="text" name="name" style="width: 500px;height: 30px"></td>
</tr>
<tr>
<td>導演：</td>
<td><input type="text" name="director" style="width: 500px;height: 30px"></td>
</tr>
<tr>
<td>內容：</td>
<td><textarea name="content" cols="30" rows="10" style="width: 500px;"></textarea></td>
</tr>
<tr content="center">
<td colspan="2" style="text-align: center"><input type="submit" value="提交"></td>
</tr>
</table>
</form>
</body>
</html>
刪除
/**
* 刪除電影
*/
public function actionGetDeleteMovie()
{
$id=$_GET['id'];
$movie=Movie::model()->findByPk($id);
$movie->delete(); // 從數據表中刪除此行
$this->redirect(array(getMovie));
}
修改
/**
* 跳轉到更新電影
*/
public function actionToUpdateMovie(){
$id=$_GET['id'];
$movie=Movie::model()->find('id=:id',array(':id'=>$id));
$this->smarty->assign('movie',$movie);
$this->smarty->display('movie/update.html');
}
/**
* 修改電影
*/
public function actionGetUpdateMovie(){
$id=$_POST['id'];
$movie=Movie::model()->find('id=:id',array(':id'=>$id));
$movie->name=$_POST['name'];
$movie->content=$_POST['content'];
$movie->director=$_POST['director'];
$movie->save(); // 將更改保存到數據庫
$this->redirect(array(getMovie));
}
HTMl
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="/movie/Movie/getUpdateMovie" method="post">
<table border="1" style="margin-top: 100px;margin-left: 100px">

</tr>
<tr>
<td>電影</td>
<td>

</td>
</tr>
<tr>
<td> <input type="submit" name="submit" value="提交">
</td>
</tr>
</table>
</form>
</body>
</html>
修改頁面
模糊查詢
需要寫SQL語句
/**
* 模糊查詢電影
*/
public function actionSearch(){
$keywords=$_POST['keywords'];
$sql = "select *
from t_movie
where t_movie.name like '%".$keywords."%'
or t_movie.director like '%".$keywords."%'
or t_movie.content like '%".$keywords."%'
";
$list = Yii::app()->db->createCommand($sql)->queryAll();
$this->smarty->assign('list',$list);
$this->smarty->display('movie/select.html');
}
HTML
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<table border="1" style="margin-top: 10px;font-size: x-large">
<thead> <tr> <th>電影</th>
<th>導演</th>
<th>內容</th> </tr>
<tr>
</thead> <tbody> <{foreach from=$list item=movie}>
<td><{$movie.name}></td><td><{$movie.director}></td><td><{$movie.content}></td> <td>
</td> </tr> <{/foreach}> <tr> <td colspan="2" style="text-align: center" > </td> </tr> </tbody>
</table>
</body>
</html>
跳轉
$this->redirect(array(getMovie)); //跳轉到同一controller的方法
$this->redirect($this->createUrl('/movie/movie/GetMovie/')); //跳轉到任意controller的方法。可傳參
$this->redirect($this->createUrl('/movie/movie/GetMovie/Id/'.$Id));
