dedecms插件开发简明教程

最心动的相遇 發表於 2024-1-14 00:00:00

本文简单讲述了dedecms插件开发的方法。分享给大家供大家参考。具体如下：

这里举的是一个很简单插件实例，通过此插件，你可以知道怎么样开发一个插件，它结构是怎么设置的，数据库，后台等。

文件结构如下：

enroll.php 文件在 plus文件下 
enroll.htm文件在templets/plus 文件夹下 
adenroll.php 文件在dede文件夹下 
adenroll.html 文件dede/templet文件夹下

sql文件如下：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode5" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
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, '');</div>



这里说明下为了方便我简单的设置了两个字段姓名和邮箱 tag字段是标示是否录取 1为录取 
第一个insert语句是添加到后台管理 
第二个insert语句是添加到前台导航栏

enroll.php文件如下：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode6" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<?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','$_POST')"; 
//********$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 
} 
?></div>



enroll.htm文件如下：
