Show comments location
Put the following functions in your functions. php
The implementation principle is to use the IP query interfaces of Sina and Taobao to return the city to which the IP belongs.
Minor repairs the code, removes the mount point, and calls the function directly when the comment is displayed.
| The code is as follows: |
Copy code |
/**
* Use the api to obtain the <a title = "View articles related to Cities" city name
* @ Param string $ ip
* @ Return string | mixed
*/
Function wpgo_get_city ($ ip = null ){
$ Ip = null? Wpgo_get_ip (): $ ip;
$ IpApi = array (
'Http: // int.dpool.sina.com.cn/iplookup/iplookup.php? Format = json & ip = ',
'Http: // ip.taobao.com/service/getIpInfo.php? Ip ='
);
Foreach ($ ipApi as $ k => $ api ){
$ Res = wp_remote_get ($ api. $ ip );
If (is_object ($ res) & $ k = 0 ){
Continue;
}
If (! Empty ($ res ['body']) {
$ Return = json_decode ($ res ['body'], true );
If (! Empty ($ return ['city']) {
Return $ return ['city'];
} Elseif ($ return ['Province '] = 'Hong Kong' | $ return ['Province '] = 'Macao '){
Return $ return ['Province '];
} Else {
Return $ return ['country'];
}
}
}
Return false;
}
/**
* Obtain the ip address of the current user.
* @ Return string
*/
Function wpgo_get_ip (){
If (getenv ("HTTP_CLIENT_IP") & strcasecmp (getenv ("HTTP_CLIENT_IP"), "unknown ")){
$ Ip = getenv ("HTTP_CLIENT_IP ");
} Elseif (getenv ("HTTP_X_FORWARDED_FOR") & strcasecmp (getenv ("HTTP_X_FORWARDED_FOR"), "unknown ")){
$ Ip = getenv ("HTTP_X_FORWARDED_FOR ");
} Elseif (getenv ("REMOTE_ADDR") & strcasecmp (getenv ("REMOTE_ADDR"), "unknown ")){
$ Ip = getenv ("REMOTE_ADDR ");
} Elseif (isset ($ _ SERVER ['remote _ ADDR ']) & $ _ SERVER ['remote _ ADDR '] & strcasecmp ($ _ SERVER ['remote _ ADDR'], "unknown ")){
$ Ip = $ _ SERVER ['remote _ ADDR '];
}
If ($ _ SERVER ['remote _ ADDR '] = '1970. 0.0.1' & $ ip = 'unknown '){
$ Ip = 'localhost ';
}
Return $ ip;

The most important section: obtain the city field before your template outputs comments. The following is a reference to the code in my template. You can only refer to the judgment method, how can I modify it based on your template?
| The code is as follows: |
Copy code |
// The administrator replies
If ($ is_admin ){
$ City = 'reply from Postmaster ';
} Else {
// Compatible with comments without city fields
$ City = get_comment_meta ($ comment-> comment_ID, 'City _ name', true );
If (! $ City ){
$ City = wpgo_get_city ($ comment-> comment_author_IP );
// If the api can normally obtain the city information, insert it to the database.
If ($ city ){
Update_comment_meta ($ comment-> comment_ID, 'City _ name', $ city );
} Else {
// If the api information cannot be obtained due to an exception, the user-defined string is returned, which is retained the next time the comments are read.
$ City = 'Mars ';
}
}
$ City = "netizens from {$ city ";

Display reviewer browser type
Put the following code into function. php.
| The code is as follows: |
Copy code |
Function getbrowser ($ Agent)
{
If ($ Agent = "")
$ Agent = $ _ SERVER ['http _ USER_AGENT '];
$ Browser = '';
$ Browserver = ''; If (ereg ('mozilla ', $ Agent) & ereg ('Chrome', $ Agent ))
{
$ Temp = explode (', $ Agent );
$ Part = $ temp [2];
$ Temp = explode ('/', $ Part );
$ Browserver = $ temp [1];
$ Temp = explode ('', $ browserver );
$ Browserver = $ temp [0];
$ Browser = 'chromi ';
}
If (ereg ('mozilla ', $ Agent) & ereg ('Firefox', $ Agent ))
{
$ Temp = explode (', $ Agent );
$ Part = $ temp [1];
$ Temp = explode ('/', $ Part );
$ Browserver = $ temp [2];
$ Temp = explode ('', $ browserver );
$ Browserver = $ temp [0];
$ Browser = 'Firefox ';
}
If (ereg ('mozilla ', $ Agent) & ereg ('Opera', $ Agent ))
{
$ Temp = explode (', $ Agent );
$ Part = $ temp [1];
$ Temp = explode (')', $ Part );
$ Browserver = $ temp [1];
$ Temp = explode ('', $ browserver );
$ Browserver = $ temp [2];
$ Browser = 'Opera ';
}
If (ereg ('mozilla ', $ Agent) & ereg ('ucbrowser', $ Agent ))
{
$ Temp = strrchr ($ Agent ,'/');
$ Browserver = substr ($ temp, 1 );
$ Browser = 'UC ';
}
If (ereg ('mozilla ', $ Agent) & ereg ('msie', $ Agent ))
{
$ Temp = explode (', $ Agent );
$ Part = $ temp [1];
$ Temp = explode (';', $ Part );
$ Part = $ temp [1];
$ Temp = explode ('', $ Part );
$ Browserver = $ temp [2];
$ Browser = 'Internet Explorer ';
}
// Add other browsers as needed
If ($ browser! = '')
{
$ Browseinfo = $ browser. ''. $ browserver;
}
Else
{
$ Browseinfo = $ Agent;
}
Return $ browseinfo;
} |
The above getbrowser () function returns the browser name + browser version. Call at the relevant location to display it. Finally, open wp-nodes des/comment-template under wordpress, find the function get_comment_author_link function, add the call function before the last return, and display the corresponding small icon function.
| The code is as follows: |
Copy code |
If ($ comment)
$ Ua = $ comment-> comment_agent;
Else
$ Ua = "";
$ Tmp = getbrowser ($ ua );
If ($ tmp! = ""){
$ Br = explode ('', $ tmp );
If (stristr ($ br [0], 'Chrome '))
$ Brimg = "/chrome.png ";
Elseif (stristr ($ br [0], 'Firefox '))
$ Brimg = "/firefox.png ";
Elseif (stristr ($ br [0], 'Opera '))
$ Brimg = "/opera.png ";
Elseif (stristr ($ br [0], 'internet '))
$ Brimg = "/ie.png ";
Elseif (stristr ($ br [0], 'Safari '))
$ Brimg = "/Safari.png ";
Elseif (stristr ($ br [0], 'UC '))
$ Brimg = "/ucweb.png ";
Else
$ Brimg = "/anonymouse.png ";
$ Return. = " ";
}

Well, it's done here. If you have time for the rest, you can complete other browsers. Currently, only simple identification of chrome, ie, firefox, and opera is supported.
