Dedecms plugin development tutorial

Introduction: This is a detailed page of dedecms plug-in development tutorial. It introduces PHP, related knowledge, skills, experience, and some PHP source code.

Class = 'pingjiaf' frameborder = '0' src = 'HTTP: // biancheng.dnbc?info/pingjia.php? Id = 325726 'rolling = 'no'>

This is a simple plug-in instance. With this plug-in, you can know how to develop a plug-in, how to set its structure, database, background, and so on.
File structure:
The enroll. php file is in the plus file.
The enroll.htm file is in the templets/plus folder.
The adenroll. php file is in the Dede folder.
Under the Dede/templet folder of the adenroll.html File
SQL file:

 
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', 'write', 'isshow ', 'filelist') values (30, 'register online ',' <m: item name = ''register online ''' link ='' adenroll. PHP ''rank = ''plus _ register online ''' target = ''main''/> ', '', 'g1000', 1 ,'');
 

For convenience, I have set two fields, name and email tag, to indicate whether admission 1 is admission.
The first insert statement is added to the background management.
The second insert statement is added to the foreground navigation bar.
