這篇文章主要介紹了基於Codeigniter框架實現的student資訊系統網站動態發布功能,詳細分析了動態網站相關的資料庫sql語句、MVC各個模組功能與實作技巧,需要的朋友可以參考下
本文實例講述了基於Codeigniter框架實現的student資訊系統站點動態發布功能。表:
CREATE TABLE IF NOT EXISTS `student`( //主键id `id` int(11) NOT NULL AUTO_INCREMENT, //学生姓名 `s_name` varchar(64) NOT NULL, //学生家长的姓名 `p_name` varchar(64) NOT NULL, //学生的家庭住址 `address` varchar(100) NOT NULL, //所在城市 `city` varchar(30) NOT NULL, //所在国家 `state` varchar(30) NOT NULL, //所在地区的邮政编码 `zip` varchar(20) NOT NULL, //电话 `phone` varchar(15) NOT NULL, //邮件 `email` varchar(20) NOT NULL, //主键设置 PRIMARY KEY(`id`) )ENGINE=INNODB DEFAULT CHARSET=UTF8 AUTO_INCREMENT=1;
*註:在此我有兩個地方需要解釋一下:
1."IF NOT EXISTS":如果資料在建立表格的時候,前面加上了"IF NOT EXISTS",那就表示即使此表已經存在,也會執行成功;
2."ENGINE=INNODB":這個是資料庫的引擎設置,常用
mysql資料庫#引擎有ISAM,MYISAM,HEAP等;在建立完資料表之後,我們再來看一下資料庫的連線。 .\application\config\config.php檔案內設定基本的URL,對於我的基本url是:localhost/codeigniter/
下面我們來看看mvc思想
的設計首先開啟.application\controllers\檔案目錄,在裡面建立一個student.php
控制器#在此我們先來透過student這個控制器來測試一下,列印出helloworld,記住存取路徑是:localhost/codeigniter/index.php/student/index
class student extends CI_Controller{ //student controller construct public function construct(){ parent::construct(); } //index test function public function index(){ echo "helloworld"; } }
it output: helloworld
#下面我們來換一下,看看下面這段code:
class student extends CI_Controller{ //student controller public function construct(){ parent::construct(); } //define a array,name is arraydata, it have three parameters protected $arraydata=array( 'title'=>'Classroom:Home page', 'headline'=>'welcome to the classroom Mangement System', 'include'=>'student_index' ); //index function public function index(){ $this->load->view('template',$this->arraydata); } }
這段程式碼需要一個
檢視<!DOCTYPE html PUBLIC '-//W3C//DTD HTML 4.01 Strict//EN' 'http://www.w3.org/TR/html4/strict.dtd'> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=utf-8'> <title><?php echo $title; ?></title> </head> <body> <h1><?php echo $headline; ?></h1> <?php $this->load->view($include)?> </body> </html>
其中:
this−>load−>view(include);
包含的是另外一個檢視檔案studen_index.php檔案
student_index.php:
<p>Congratulations. Your initial setup is complete!</p>
共同輸出:
welcome to the classroom Mangement System Congratulations. Your initial setup is complete!資料的CURD
C 控制器
#先來看看資料增加的過程,在student控制器中增加一個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 視圖
template .php
<html> <head> <title><?php echo $title;?></title> </head> <body> <h1><?php echo $headline ?></h1> <?php $this->load->view($include)?> </body> </html>
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');
}
}
