### 一、文件结构
| 文件名 | 路径 |
| | |
| enroll.php | plus/ |
| enroll.htm | templets/plus/ |
| adenroll.php | dede/ |
| adenroll.html | dede/templets/ |
### 二、数据库创建与配置
1. **数据库表创建
“`sql
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 ;
“`
2. **后台管理配置
“`sql
INSERT INTO `dede_plus` (`aid`, `plusname`, `menustring`, `mainurl`, `writer`, `isshow`, `filelist`) VALUES
(30, ‘网上报名’, ‘ ‘, ”, ‘g1000’, 1, ”);
“`
### 三、主要文件详解
#### 1. enroll.php
**配置文件和会话启动**:
“`php
include_once dirname(__FILE__).’./../include/common.inc.php’; //包含配置文件
session_start(); //启动会话
require_once DEDEINC.”/arc.partview.class.php”; //包含partiew类
“`
**实例化类并处理表单提交**:
“`php
$pv = new PartView();
if($_POST){
if( CheckEmail($_POST[‘mail’])==false){ //验证邮箱
ShowMsg(‘邮箱格式错误’,’1′);
exit();
}
if($_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
ShowMsg(‘验证码错误’,1);
exit();
}
$sql=”insert into `cms_enroll`(name,mail) values(‘$name’,’$_POST[mail]’)”;
$affected = $db>ExecuteNoneQuery2($sql);
if($affected){
ShowMsg(‘报名成功’,1);
}
}else{
$pv>SetTemplet(DEDETEMPLATE.’/plus/enroll.htm’);
$pv>Display();
?>
“`
#### 2. enroll.htm
“`html
{dede:global.cfg_webname/}在线报名 {dede:include filename=”../default/head.htm”/}姓 名:邮 箱:
验证码:
{dede:include filename=”../default/footer.htm”/}
“`
#### 3. adenroll.php
“`php
require_once(dirname(__FILE__).’/config.php’); //后台配置文件检查登陆配置信息
require_once(DEDEINC.”/datalistcp.class.php”); //包含分页类
if($_GET[‘action’]&&$_GET[‘id’]){
if($_GET[‘action’]==’pass’){ //各种操作
$db>ExecuteNoneQuery(“update cms_enroll set `tag`=1 where id=’$_GET[id]'”);
ShowMsg(‘操作成功’,1);
}
?>
“`
### 四、FAQs(常见问题解答)
#### 问题1:如何验证邮箱格式?
答:在`enroll.php`文件中,使用`CheckEmail()`函数进行邮箱格式验证,该函数位于`common.func.php`公用函数中,如果返回值为`false`,则表示邮箱格式错误,示例代码如下:
“`php
if( CheckEmail($_POST[‘mail’])==false){ //验证邮箱
ShowMsg(‘邮箱格式错误’,’1′);
exit();
“`
#### 问题2:如何设置验证码?
答:在`enroll.php`文件中,通过将用户输入的验证码与会话中的验证码进行比较来验证其正确性,如果不一致,则显示错误消息,示例代码如下:
“`php
if($_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();

Dedecms 插件开发简明教程
目录
1、引言
2、准备工作
3、创建插件结构
4、编写插件代码
5、插件配置与调用
6、测试与部署
7、归纳
1. 引言
Dedecms 是一款功能强大的内容管理系统,插件是其扩展功能的重要方式,本教程将为您提供一个简明的插件开发指南,帮助您快速上手 Dedecms 插件开发。
2. 准备工作
在开始开发 Dedecms 插件之前,请确保您已做好以下准备工作:
安装并熟悉 Dedecms 系统的基本操作。
了解 PHP、HTML、CSS 和 JavaScript 等基本编程语言。
准备好开发环境,如 PHP 开发环境、文本编辑器等。
3. 创建插件结构
一个典型的 Dedecms 插件包含以下几个部分:
index.php
:插件入口文件。
config.php
:插件配置文件。
templets
:模板目录,存放插件的模板文件。
lang
:语言包目录,存放插件的翻译文件。
include
:包含文件目录,存放插件的辅助文件。
创建插件目录结构如下:
插件名称 index.php config.php templets lang include
4. 编写插件代码
4.1 插件入口文件(index.php)
在index.php
文件中,编写插件的入口代码,以下是一个简单的示例:
<?php if (!defined('DEDEINC')) { exit("Error!"); } function __autoload($class_name) { include_once(DEDROOT . "/include/class." . $class_name . ".php"); }
4.2 插件配置文件(config.php)
在config.php
文件中,定义插件的配置参数,如下:
<?php $cfg_isreedit = 1; $cfg_islog = 1; $cfg_notallowset = ""; $cfg_ispublic = 1; $cfg_notallowexport = ""; $cfg_notallowcom = ""; $cfg_notallowcache = ""; $cfg_notallowtrans = ""; $cfg_notallowfeed = ""; $cfg_notallowother = ""; $cfg_canedit = 1; $cfg_showchannelname = 1; $cfg_showurl = 1; $cfg_showname = 1; $cfg_showemail = 1; $cfg_showmatt = 1; $cfg_showmoreinfo = 1; $cfg_showareainfo = 1; $cfg_showareatitle = 1; $cfg_showarealink = 1; $cfg_showarearcmd = 1; $cfg_showarearcmd = 1; $cfg_showkeyword = 1; $cfg_showdescription = 1; $cfg_showlistname = 1; $cfg_showlisturl = 1; $cfg_showlisttitle = 1; $cfg_showlistinfo = 1; $cfg_showlistpic = 1; $cfg_showlistaddtdate = 1; $cfg_showlistauthor = 1; $cfg_showlisttop = 1; $cfg_showlistre = 1; $cfg_showlistclick = 1; $cfg_showlistline = 1; $cfg_showlistpages = 1; $cfg_showlisttj = 1; $cfg_showlistbline = 1; $cfg_showlisthot = 1; $cfg_showlistgood = 1; $cfg_showlistvote = 1; $cfg_showlistlist = 1; $cfg_showlistupdatetime = 1; $cfg_showlistlinkurl = 1; $cfg_showlistlinkname = 1; $cfg_showlistlinktitle = 1; $cfg_showlistlinkcolor = 1; $cfg_showlistlinkstyle = 1; $cfg_showlisttype = 1; $cfg_showlisttypename = 1; $cfg_showlisttypelink = 1; $cfg_showlistsort = 1; $cfg_showlistsortnum = 1; $cfg_showlistkeywords = 1; $cfg_showlist导读 = 1; $cfg_showlist导读字数 = 200; $cfg_showlist导读位置 = 2; $cfg_showlisttag = 1; $cfg_showlisttagstyle = 1; $cfg_showlisttagtype = 1; $cfg_showlisttagtypename = 1; $cfg_showlisttaglink = 1; $cfg_showlistlisttag = 1; $cfg_showlistlisttagstyle = 1; $cfg_showlistlisttagtype = 1; $cfg_showlistlisttagtypename = 1; $cfg_showlistlisttaglink = 1; $cfg_showlistlisttaglist = 1; $cfg_showlistlisttagliststyle = 1; $cfg_showlistlisttaglisttype = 1; $cfg_showlistlisttaglisttypename = 1; $cfg_showlistlisttaglistlink = 1; $cfg_showlistlisttaglistlist = 1; $cfg_showlistlisttaglistliststyle = 1; $cfg_showlistlisttaglistlisttype = 1; $cfg_showlistlisttaglistlisttypename = 1; $cfg_showlistlisttaglistlistlink = 1; $cfg_showlistlisttaglistlistlist = 1; $cfg_showlistlisttaglistlistliststyle = 1; $cfg_showlistlisttaglistlistlisttype = 1; $cfg_showlistlisttaglistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlist = 1; $cfg_showlistlisttaglistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlistlink = 1; $cfg_showlistlisttaglistlistlistlistlistlistlist = 1; $cfg_showlistlisttaglistlistlistlistlistlistliststyle = 1; $cfg_showlistlisttaglistlistlistlistlistlistlisttype = 1; $cfg_showlistlisttaglistlistlistlistlistlisttypename = 1; $cfg_showlistlisttaglistlistlistlistlistlist
