How to Display a User’s IP Address in WordPress

Today i am going to share with you a sweet WordPress tutorial that will enable your WordPress blog to display visitor's IP(Internet Protocol) address using a ShortCode.

Add IP detection to your Wordpress Blog:

Only Thing you need to do is copy and paste below code snippet in your functions.php file 

// Display User IP in WordPress Blog
function get_the_user_ip() {
if ( ! empty( $_SERVER['HTTP_CLIENT_IP'] ) ) {
//check ip from share internet
$ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif ( ! empty( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
//to check ip is pass from proxy
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
return apply_filters( 'wpb_get_ip', $ip );
}
add_shortcode('show_his_ip', 'get_the_user_ip');

Next thing you need to do is add the following shortcode in your post, page, or in a sidebar widget.

[show_his_ip]

Now your visitors will see the IP address from where they are visiting on your WordPress Blog.
