dedecms plug-in development tutorial, dedecms plug-in tutorial

This is a very simple plug-in example. Through this plug-in, you can know how to develop a plug-in and how its structure is set up. , database, backend, etc.
File structure:
enroll.php file is under the plus file
enroll.htm file is under the templates/plus folder
adenroll.php file is under the dede folder
adenroll.html file
sql file in dede/templet folder:

CREATE TABLE IF NOT EXISTS `dede_enroll` (
`id` int(4) NOT NULL auto_increment,
`name` varchar(20) NOT NULL,
`mail` varchar(30) NOT NULL,
`tag` tinyint(1) NOT NULL default '0',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

INSERT INTO `dede_plus` (`aid`, `plusname`, `menustring`, `mainurl`, `writer`, `isshow`, `filelist`) VALUES
(30, '网上报名', '<m:item name=''网上报名'' link=''adenroll.php'' rank=''plus_网上报名'' target=''main'' />', '', 'g1000', 1, '');

For convenience, I have simply set up two fields: name and email tag. The fields indicate whether to admit or not. 1 is admission.
The first insert statement is added to the background management.
The second insert statement is Add to front navigation bar

enroll.php

<?php 
//*******要先包含common.inc.php 然后 session_start(); 否则取不到session的值 
//*******因为common.inc.php 有关于session路径的配置 
include_once dirname(__FILE__).'./../include/common.inc.php';//包含配置文件 
session_start(); 
require_once DEDEINC."/arc.partview.class.php";//包含partiew类 
//*****实例化 这个类的作用是得到头部导航栏和尾部信息 若不需要可以使用dedetemplate.class.php 这个类 
$pv = new PartView(); 
if($_POST){ 
if( CheckEmail($_POST['mail'])==false){//验证邮箱 方法在common.func.php 公用函数 
ShowMsg('邮箱格式错误','-1'); 
exit(); 
} 
if($_POST['name']==""){ 
ShowMsg('用户名不能为空','-1'); 
exit(); 
}else{ 
$name=htmlspecialchars($_POST['name']); 
} 
if($_SESSION['dd_ckstr']!=strtolower($_POST['validation'])){//验证 验证码 必须转换成小写 
ShowMsg('验证码错误',-1); 
exit(); 
} 
$sql="insert into `cms_enroll`(name,mail) values('$name','$_POST[mail]')"; 
//********$db可直接使用 系统自动实例化了dedesql.class.php 
$affected = $db->ExecuteNoneQuery2($sql);//执行一条语句 返回影响值 
if($affected){ 
ShowMsg('报名成功',-1); 
} 
}else{ 
$pv->SetTemplet(DEDETEMPLATE.'/plus/enroll.htm');//设置模板 
$pv->Display();//显示页面

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
