thinkphp学习之路（二）
数据的CURD操作：
1.创建一个表：
CREATE TABLE IF NOT EXISTS `think_form` ( `id` smallint(4) unsigned NOT NULL AUTO_INCREMENT, `title` varchar(255) NOT NULL, `content` varchar(255) NOT NULL, `create_time` int(11) unsigned NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ;
2.创建FormAction.class.php
<?php
class FormAction extends Action {
public function insert(){
$form = D('Form');
if($form->create()){
$result = $form->add();
if($result){
$this->success('操作成功！');
}else{
$this->error('写入错误！');
}
}else{
$this->error($form->getError());
}
}
public function read($id=0){
$Form = M('Form');
// 读取数据
$data = $Form->find($id);
if($data) {
$this->data = $data;// 模板变量赋值
}else{
$this->error('数据错误');
}
$this->display();
}
public function edit($id=0){
$Form = M('Form');
$this->vo = $Form->find($id);
$this->display();
}
public function update(){
$Form = D('Form');
if($Form->create()) {
$result = $Form->save();
if($result) {
$this->success('操作成功！');
}else{
$this->error('写入错误！');
}
}else{
$this->error($Form->getError());
}
}
public function delete($id=0){
$Form = M('Form');
$Form->delete($id);
}
}
4.FormModel.class.php
class FormModel extends Model {
//定义自动验证
protected $_validate = array(
array('title','require','标题必须'),
);
//定义自动完成
protected $_auto = array(
array('create_time','time',1,'function'),
);
}
5.add.edit.read三个模板
<html> <head> <title>CURD</title> </head> <body> <FORM method="post" action="insert"> 标题：<INPUT type="text" name="title"><br/> 内容：<TEXTAREA name="content" rows="5" cols="45"></TEXTAREA><br/> <INPUT type="submit" value="提交"> </FORM> </body> </html>
<html>
<head>
<title>CURD</title>
</head>
<body>
<table>
<tr>
<td>id:</td>
<td>{$data.id}</td>
</tr>
<tr>
<td>标题：</td>
<td>{$data.title}</td>
</tr>
<tr>
<td>内容：</td>
<td>{$data.content}</td>
</tr>
</table>
</body>
</html>
<html>
<head>
<title>CURD</title>
</head>
<body>
<FORM method="post" action="/update">

内容：<TEXTAREA name="content" rows="5" cols="45">{$vo.content}</TEXTAREA><br/>
<INPUT type="hidden" name="id" value="{$vo.id}">
<INPUT type="submit" value="提交">

</body>
