数据的CURD
C 控制器
先来看看数据的增加过程，在student控制器中增加一个add()方法
class student extends CI_Controller{
//student controller
public function __construct(){
parent::__construct();
}
//new add function
public function add(){
$this->load->helper('form');
//display information for the view
$data['title']='Classroom:Add Page';
$data['headline']='Add data';
$data['include']='student_add';
//upload view
$this->load->view('template',$data);
}
//create function
public function create(){
$this->load->helper('url');
$this->load->model('MStudent','',TRUE);
$this->MStudent->addData($_POST);
redirect('student/add','reflesh');
}
//update function
public function update(){
//upload codeigniter library
$this->load->library('table');
$this->load->model('MStudent','',TRUE);
$student_query=$this->MStudent->updateData();
$update_table=$this->table->generate($student_query);
//display information for the view
$data['title']='Classroom:Update Page';
$data['headline']='Update Page';
$data['include']='update_student';
$data['updatetable']=$update_table;
$this->load->view('template',$data);
}
//index function
public function index(){
$data['title']='Classroom:Home page';
$data['headline']='welcome to classroom Mangement System';
$data['include']='student_index';
$this->load->view('template',$this->arraydata);
}
}
V 视图
template .php
<html>
<head>
<title><?php echo $title;?></title>
</head>
<body>
<h1><?php echo $headline ?></h1>
<?php $this->load->view($include)?>

student_add.php
<?php
echo form_open('student/create');
$field_name=array('s_name','p_name','address','city','state','zip','phone','email');
foreach($field_name as $value){
echo "<p>".$value.":"
echo form_input(array('name'=>$value));
echo "</p>"
}
form_submit('','Add');
form_close();
?>
update_student.php
<?php echo $updatetable; ?>
M 模型
class MStudent extends CI_Model{
public function addData($data){
$this->db->insert('student',$data);
}
public function updateData(){
$this->db->get('student');
}
}
