Allow HTTP_USER_AGENT to collect data from users.

WP doesn’t block things like HTTP_USER_AGENT. Are you grabbing the value using $_SERVER[‘HTTP_USER_AGENT’]?

I found a very useful function for detecting user os and browser ,
it works very well , but when i put it inside wordpress
it doenst work .

`<?php
$user_agent = $_SERVER[‘HTTP_USER_AGENT’];
function getOS() {
global $user_agent;
$os_platform = “Unknown OS Platform”;
$os_array = array(
‘/windows nt 10/i’ => ‘Windows 10’,
‘/windows nt 6.3/i’ => ‘Windows 8.1’,
‘/windows nt 6.2/i’ => ‘Windows 8’,
‘/windows nt 6.1/i’ => ‘Windows 7’,
‘/windows nt 6.0/i’ => ‘Windows Vista’,
‘/windows nt 5.2/i’ => ‘Windows Server 2003/XP x64’,
‘/windows nt 5.1/i’ => ‘Windows XP’,
‘/windows xp/i’ => ‘Windows XP’,
‘/windows nt 5.0/i’ => ‘Windows 2000’,
‘/windows me/i’ => ‘Windows ME’,
‘/win98/i’ => ‘Windows 98’,
‘/win95/i’ => ‘Windows 95’,
‘/win16/i’ => ‘Windows 3.11’,
‘/macintosh|mac os x/i’ => ‘Mac OS X’,
‘/mac_powerpc/i’ => ‘Mac OS 9’,
‘/linux/i’ => ‘Linux’,
‘/ubuntu/i’ => ‘Ubuntu’,
‘/iphone/i’ => ‘iPhone’,
‘/ipod/i’ => ‘iPod’,
‘/ipad/i’ => ‘iPad’,
‘/android/i’ => ‘Android’,
‘/blackberry/i’ => ‘BlackBerry’,
‘/webos/i’ => ‘Mobile’
);foreach ($os_array as $regex => $value) {
if (preg_match($regex, $user_agent)) {
$os_platform = $value;
}
}
return $os_platform;}
function getBrowser() {
global $user_agent;
$browser = “Unknown Browser”;
$browser_array = array(
‘/msie/i’ => ‘Internet Explorer’,
‘/firefox/i’ => ‘Firefox’,
‘/safari/i’ => ‘Safari’,
‘/chrome/i’ => ‘Chrome’,
‘/opera/i’ => ‘Opera’,
‘/netscape/i’ => ‘Netscape’,
‘/maxthon/i’ => ‘Maxthon’,
‘/konqueror/i’ => ‘Konqueror’,
‘/mobile/i’ => ‘Handheld Browser’
);
foreach ($browser_array as $regex => $value) {
if (preg_match($regex, $user_agent)) {
$browser = $value;
}
}
return $browser;}
$user_os = getOS();
$user_browser= getBrowser();
$device_details = “<strong>Browser: </strong>”.$user_browser.”
<strong>Operating System: </strong>”.$user_os.””;
print_r($device_details);
?>`

Can someone help me please ? It is very important.

Thank you!

You just need another global $user_agent; line outside of function declarations. Put it as 1st line in your code above, right after <?php

@bcworkz thank you so much my friend .
It worked ?? !
