Check the geographical location corresponding to the user's IP in the ShopEX backend

This article can enable ShopEX to check the geographical location information corresponding to the user's registered IP in the background, obtain the information of the Innocence IP database through functions and return it to the template, without writing to the database. The function to obtain the innocent IP is modified from the source code of Discuz!. The code for obtaining IP information can be used for other types of websites with slight modifications, and supports UTF-8 and GBK encoding.

The effect before modification:

(1) Preparation:

Download the latest innocent IP database qqwry.dat

Create the file pure_get.php with the following code:

<?php
//包含ShopEX根目录下的配置文件

// 参数：$mid 即是用户id

	//连接数据库通过id获取ip
	$ip_dbconn = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD);

	if($ip_dbconn){
		$ip_dbsel = mysql_select_db(DB_NAME,$ip_dbconn);
		$ip_dbquery = 'SELECT reg_ip FROM `'.DB_PREFIX.'members` WHERE member_id='.$ip_mid;
		$ip_dbresult = mysql_query($ip_dbquery, $ip_dbconn);
		$ip_addr = mysql_result($ip_dbresult,0,0);

	//关闭数据库

(2) Upload files:

Place qqwry.dat in the ShopEX root directory and pure_get.php in the "shopex\core\admin\controller\member" directory

(3) Modify the code:

Open shopex\core\admin\controller\member\ctl.member.php and find the function function show_detail($nMId)

Inside the function add:

		// 修改：获取注册ip地址信息
		// 这里要注意函数 convertip 的参数一定要填对  不然会乱码
		include_once('pure_get.php');
		$ip_addr = convertmid($nMId); 
		$ip_location = convertip($ip_addr, 0, 1);
		$this->pagedata['ip_location'] = $ip_location;

Open the template shopex\core\admin\view\member\member_items.html and find <{$mem.reg_ip}>

Add at the end:

<label><{$ip_location}></label>

Note that $ip_location in member_items.html corresponds to pagedata[ip_location'] in the function show_detail. You can set some other values first to test the display results.

(4) Test:

Check the effect in the background

(5) Description:

The function convertmid($mid) in pure_get.php is used to obtain the registered IP address of ShopEX using the user ID. This function is actually not very safe, but I currently don’t understand the code of ShopEX well enough and I can’t find a good method for the time being. It is a security measure to call the config file instead of directly using the database account and password.

If you can directly find the IP address variable, you can use convertip($ip, $a1, $a2) to access the innocence database and obtain the address information. Remember to add parameters, otherwise it will cause two errors: the IP database cannot be accessed or garbled characters are returned.
