User's Browser

[adam87]

Hey I'm currently working on a project an have been asked to store which browser the user is using. I was wondering if any one can point me in the way of a tutorial. I have searched but came back with nothing

You could use the variable, $_SERVER['HTTP_USER_AGENT'] . Which returns the webbrowsers version and OS the client is using.

[Maq]

An example straight from the manual:

 

function get_user_browser()
{
    $u_agent = $_SERVER['HTTP_USER_AGENT'];
    $ub = '';
    if(preg_match('/MSIE/i',$u_agent))
    {
        $ub = "ie";
    }
    elseif(preg_match('/Firefox/i',$u_agent))
    {
        $ub = "firefox";
    }
    elseif(preg_match('/Safari/i',$u_agent))
    {
        $ub = "safari";
    }
    elseif(preg_match('/Chrome/i',$u_agent))
    {
        $ub = "chrome";
    }
    elseif(preg_match('/Flock/i',$u_agent))
    {
        $ub = "flock";
    }
    elseif(preg_match('/Opera/i',$u_agent))
    {
        $ub = "opera";
    }
   
    return $ub;
}
?>

Instead of starting a new topic, basically I had this working and storing it to mysql satabase, but working on it today and some how managed to stuff it up!

 

 

<?
include 'dbc.php';


	$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);

        // Identify the browser. Check Opera and Safari first in case of spoof. Let Google Chrome be identified as Safari.
        if (preg_match('/opera/', $userAgent)) {
            $name = 'opera';
        }
        elseif (preg_match('/webkit/', $userAgent)) {
            $name = 'safari';
        }
        elseif (preg_match('/msie/', $userAgent)) {
            $name = 'ie';
        }
        elseif (preg_match('/mozilla/', $userAgent) && !preg_match('/compatible/', $userAgent)) {
            $name = 'firefox';
        }
        else {
            $name = 'unrecognized';
        } 

$query = "INSERT INTO browser (browser) VALUES ('$name')";
mysql_query ($query, $linkme)
or die ("Could not add the data to table");
	   
	   
        ?>

 

It saying "Could not add the data to table", but I had it previously working and cannot remember what I changed!

[Maq]

Change this line to (it will give a more descriptive error message) :

 

   mysql_query ($query, $linkme) or die (mysql_error());

Right got it to work, basically was a problem with mysql table, but now I have run in to another error, basically I've got a a session which is started when the user as logged in, this get the users_id. bascially i want to get that user Id and store it to my database, below is the code im trying:

 

<?
include 'dbc.php';


$user_id = $_REQUEST['uid'];
$page = strtolower($_SERVER['PHP_SELF']);
	$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);

        // Identify the browser. Check Opera and Safari first in case of spoof. Let Google Chrome be identified as Safari.
        if (preg_match('/opera/', $userAgent)) {
            $name = 'opera';
        }
        elseif (preg_match('/webkit/', $userAgent)) {
            $name = 'safari';
        }
        elseif (preg_match('/msie/', $userAgent)) {
            $name = 'ie';
        }
        elseif (preg_match('/mozilla/', $userAgent) && !preg_match('/compatible/', $userAgent)) {
            $name = 'firefox';
        }
        else {
            $name = 'unrecognized';
        } 

	  	$query = "INSERT INTO browser  (browser, page_visted, user_id) VALUES ('$name', '$page', '$user_id')";
		mysql_query ($query, $linkme) or die (mysql_error());
	   
	   
        ?>

 

uid is the name of my session that get the user’s ID, I’m using the following code to do this  $_SESSION['uid'] = $assoc['id'];

[Maq]

Where?  I don't see any trace of sessions in your code.

 

Couple things I noticed:

  1) Don't use short tags () always use <?php

  2) Make sure you put "session_start();" at the top of your page before you assign the id from the session.

[adam87]

Right made the adjustments (cant believe i forgot the session tags) I am now not getting any error message but its not adding to the database. Below is the current code I have.

 

<?php 
session_start();

include 'dbc.php';


$user_id = $_REQUEST['uid'];
$page = strtolower($_SERVER['PHP_SELF']);
	$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);

        // Identify the browser. Check Opera and Safari first in case of spoof. Let Google Chrome be identified as Safari.
        if (preg_match('/opera/', $userAgent)) {
            $name = 'opera';
        }
        elseif (preg_match('/webkit/', $userAgent)) {
            $name = 'safari';
        }
        elseif (preg_match('/msie/', $userAgent)) {
            $name = 'ie';
        }
        elseif (preg_match('/mozilla/', $userAgent) && !preg_match('/compatible/', $userAgent)) {
            $name = 'firefox';
        }
        else {
            $name = 'unrecognized';
        } 

	  	$query = "INSERT INTO browser  (browser, page_visted, user_id) VALUES ('$name', '$page', '$user_id')";
		mysql_query ($query, $linkme) or die (mysql_error());
	   
	   
        ?>

What does the error message say?

 

uid is the name of my session that get the user’s ID, I’m using the following code to do this  $_SESSION['uid'] = $assoc['id'];

 

I'm confused...  In the statement above you claimed you were using sessions, but in your code you don't use them.  If you're referring to this line, that's not using sessions.

 

   $user_id = $_REQUEST['uid'];

There isn't one. Just dont add to the database

I've declared the session when the user logs in this is on the home page. I will post my homepage hopefully that'll clear up what I'm tryna explain

 

Loginpage/hompage

 

<?php 
session_start();

include 'dbc.php';
include 'browser.php';


$user_name = mysql_real_escape_string($_POST['uname']);

if ($_POST['Submit']=='Login')
{
$md5pass = md5($_POST['pwd']);
$sql = "SELECT id,user_name FROM users WHERE 
            user_name = '$user_name' AND 
            user_pwd = '$pwd' AND user_activated='1'"; 
         
$result = mysql_query($sql) or die (mysql_error()); 
$num = mysql_num_rows($result);
$assoc = mysql_fetch_assoc($result);

    if ( $num != 0 ) { 

   $_SESSION['user']= $user_name;
   $_SESSION['uid'] = $assoc['id'];
      
      list($user_id,$user_name) = mysql_fetch_row($result);

      
         
      if (isset($_GET['ret']) && !empty($_GET['ret']))
      {
      header("Location: $_GET[ret]");
      } else
      {
      header("Location: index.php");
      }
      //echo "Logged in...";
      exit();
    } 

header("Location: index.php?msg=Invalid Login");
//echo "Error:";
exit();      
}

?>
