wordpress how to implement the php shortcode

Question

I have tried to implement the code which can get the user region when the user open the page but it is not working i have used this code inside the functions.php

function user_region() { 
       $ip = $_SERVER['REMOTE_ADDR'];
       $details = json_decode(file_get_contents("http://ipinfo.io/{$ip}"));
        return '<div class="user-region">'.$details->region.'</div>';  
    }  
    add_shortcode("get-user-region", "user_region"); 

this is my shortcode inside the functions.php and i have used the shortcode inside the wordpress page

<?php echo get-user-region_callback(); ?>
<?php echo do_shortcode('[get-user-region]') ?>

I have tried both ways but both are not working no results are showing from this shortcode.

Answer 1

First of all, your URL to ipinfo is incorrect. If are treating the response as JSON, but the output of https://ipinfo.io/ip is HTML. You need to specify https://ipinfo.io/ip is HTML. You need to specify /json` at the end:

https://ipinfo.io/{$ip}/json

Other than that, you need to check that file_get_content is enabled on your platform and that it allows remote url loading (setting allow_url_fopen ).
