Destoon is the preferred solution for open source B2B (e-commerce) industry portal based on PHP+MySQL. This article briefly describes the secondary development of Destoon as follows:

1. Initialization system

Include common.inc.php in the system root directory to initialize the system.

For example, create a hello.php in the root directory of the site, the code is as follows:

<&#63;php
require 'common.inc.php';
echo 'Hello World';
&#63;>

Copy after login

2. Writing logic

After the system is initialized, you can write logic code in the php file, and you can also call the system's built-in variables, functions and classes.

The sample code is as follows:

<&#63;php
require 'common.inc.php';
echo DT_ROOT;//输出站点的物理路径
echo '<br/>';
echo DT_PATH;//输出站点的首页地址
echo '<br/>';
$r = $db->get_one("SELECT * FROM {$DT_PRE}category");//从分类表里查询一条数据
print_r($r);//打印读取的数据
$A = cache_read('area.php');//读取系统的地区缓存
print_r($A);//打印读取的数据
print_r($MODULE);//打印系统模块数据
message('Hello World');//输出一段提示信息
&#63;>

Copy after login

3. Application Template

All HTML output to the browser is displayed through the rules in the template.

How to use:

include template('a', 'b');

Copy after login

Parameter a represents the template name
Parameter b represents the directory where the template is stored. This parameter does not need to be set

If the template directory is default, then:

template('a', 'b'); represents template/default/b/a.htm template file
template('a'); represents template/default/a.htm template file

The sample code is as follows:

<&#63;php
require 'common.inc.php';
template('hello');
&#63;>

Copy after login

In addition, the template/default/hello.htm template file needs to be created in advance

in the system root directory
