PHP - Php Only Works When I’m Logged Into Wordpress.

Hi guys,

Have a wierd scenario where my brain is simply refusing to think. 

I have small script which let's a user log in through a login screen. Thats ok.
I can check whether the user is already logged in the same machine through sessions.

My requirement is :
I need to restrict the same username logging in from multiple computers at any one given time.
In other words, a user can not use two machines to login at the same time.

Can someone please suggest a method to solve this scenario.
Your help is very much appreciated.

Cheers

Hello all,

This has probably been asked before but I couldn't find through search.

And I'm pretty sure is not possible, but...

Is there a way of displaying the windows logged on user?
or
get the name of the compter? as I know I can get the ip address.

The reason I ask.
Each user has their own network account but on occasion we need to log on a user as a generic account we have. And I want to check if it's this user accessing the page so different options etc can be displayed.
I could use the computer name to check this as we log all activity. I could then query the log using the comp name to find logged on user.
Unfortunately the log does not hold ip, which would seem obvious but it doesn't 

Many Thanks

Hi, I want have this code (below), how would I check if a user is logged in?  I want to make it so they can only see 500 chars, or the full thing if they're logged in.  Thanks! 
Code: [Select]
  public function __construct( $data=array() ) {
    if ( isset( $data['id'] ) ) $this->id = (int) $data['id'];
    if ( isset( $data['publicationDate'] ) ) $this->publicationDate = (int) $data['publicationDate'];
    if ( isset( $data['title'] ) ) $this->title = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['title'] );
    if ( isset( $data['summary'] ) ) $this->summary = preg_replace ( "/[^\.\,\-\_\'\"\@\?\!\:\$ a-zA-Z0-9()]/", "", $data['summary'] );
    if ( isset( $data['content'] ) ) $this->content = $data['content'];
if ( isset( $data['tags'] ) ) $this->tags = $data['tags'];
  }

Hi. I'm new to php. I created a register, log in, welcome, and log out page for my site. They are all working accordingly. I'm having one problem that I can't seem to fix. I would like to stay logged in as I navigate other pages of my site. Everytime i click on a link to another page within my site I get logged out. I know this issue might pertain to using session but thats all I was able to find using google search. Can anyone help? Much appreciated.

In the site I am making, the client wants one account for everyone (don't ask me why, it's a long, silly reason)  And I'm wondering how I would configure mySQL to deal with that (I asked this in the mySQL area) and in PHP (For you guys ) what would I need to put in order for this to work.  I'm very new with PHP and mySQL, so please forgive the nooby question. 

*EDIT* the admins have their own username and psw for adding, deleting, and editing articles.  and that works.  But all users that register will have this set user and psw displayed to them.  I want to make it so they have to log in to see an article.

Hi there,   I've been searching the internet for the best way to check if the user has been logged in. Some codes have security breaches. So I'm not sure where to start.   Here's what I've come up with:   The user logs in and is checked whether he/she is a valid user, if not return false and if true carry on and create session, I read the post that Jacques1 made about session feedback and implemented what he said. After that the session variables are assigned and then the user id, session_id and a unique identifier to check against on each page load are inserted into a database and then the user is logged in.   Here's my code: (please note this is in a class and only shows the login function)

function Login($username, $password)
	{
		try
		{
			$db = new PDO("mysql:host=".DB_HOST.";dbname=".DB_NAME.";charset=utf8", DB_USERNAME, DB_PASSWORD);
			$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
			$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
		}
		catch(PDOException $ex)
		{
			echo "Unable to connect to DB";
			error_log($ex->getMessage());
		}
		
		try
		{
			$User_Info = $db->prepare("SELECT * FROM users WHERE username=:username");
			$User_Info->bindValue(":username", $username, PDO::PARAM_STR);
			$User_Info->execute();
			$Info = $User_Info->fetchAll(PDO::FETCH_ASSOC);
			
			$salt = $Info['salt'];
			
			$password = $salt . $password;
			$password = $this->CreateHash($password);
			
			$unique_key = $this->GenerateRandom();
			$unique_key = $this->CreateHash($unique_key);		
			
			$Check_User = $db->prepare("SELECT * FROM users WHERE username=:username AND password=:password");
			$Check_User->bindValue(":username", $username, PDO::PARAM_STR);
			$Check_User->bindValue(":password", $password, PDO::PARAM_STR);
			$Check_User->execute();	
			
			if($Check_User->rowCount() > 0)
			{
				while($row = $Check_User->fetchAll(PDO::FETCH_ASSOC))
				{
					session_destroy();
					session_start();
					
					$_SESSION = array();
					
					session_regenerate_id(true);
					
					$_SESSION['username'] = $row['username'];
					$session_id = session_id();
					$user_id = $row['id'];
					
					$Check_Logged_In = $db->prepare("DELETE FROM logged_in_users WHERE user_id=:userid");
					$Check_Logged_In->bindValue(":user_id", $user_id, PDO::PARAM_STR);
					$Check_Logged_In->execute();
					$has_changed = $Check_Logged_In->rowCount();
					
					if($has_changed > 0)
					{
						$Logged_In = $db->prepare("INSERT INTO logged_in_users (id, user_id, session_id, unique_key) VALUES (NULL, :user_id, :session_id, :unique_key)");
						$Logged_In->bindValue(":user_id", $user_id, PDO::PARAM_STR);
						$Logged_In->bindValue(":session_id", $session_id, PDO::PARAM_STR);
						$Logged_In->bindValue(":unique_key", $unique_key, PDO::PARAM_STR);
						$Logged_In->execute();
						$affected_rows = $Logged_In->rowCount();
						
						if($affected_rows > 0)
						{
							return true;
						}
					}
					return false;
				}
			}

			return false;
		}
		catch(PDOException $ex)
		{
			echo "Unable to complete query";
			error_log($ex->getMessage());
		}
	}

Thanks

hello i am stuck and hoping you can help, i have created this function and its not working correctly, what i am trying to do is
when someone is logged in they get this line of code echo "<a href=\"update-content.php?id=5\">Edit</a> | <a href=\"delete-content.php?id=5\">Delete</a>"; which is ok as i dont want that to work yet and if your not logged in you dont get it.
i have added //show when logged in and show not logged in so you know which code i want it to load when
at the moment its only loading the not logged in one even if you are.
i have looked on google read up on php sites but cant figure out how to do it, so hoping you guys will tell me were i gone wrong and how to correct it, thanks again

heres the code.

function get_left() {

        if (isset($_GET['page']))
 {

$page = $_GET['page'];

 

//Show Page not logged in
                $sql = "SELECT title,body FROM content WHERE page = '$page' AND location = 'left' AND disabled = 'no' ORDER BY id";
                $res = mysql_query($sql) or die (mysql_error());
                while($row = mysql_fetch_assoc($res)){

echo '<h1>' . $row['title'] . '</h1>';
                    echo '<p>' . $row['body'] . '</p>'; 

}

 }
//show when logged in
 elseif ($_SESSION['username']&&(isset($_GET['page']))){

$sql = "SELECT title,body FROM content WHERE page = '$page' AND location = 'left' AND disabled = 'no' ORDER BY id";
                $res = mysql_query($sql) or die (mysql_error());
                while($row = mysql_fetch_assoc($res)){

echo '<h1>' . $row['title'] . '</h1>';

                    echo '<p>' . $row['body'] . '</p>';

echo "<a href=\"update-content.php?id=5\">Edit</a> | <a href=\"delete-content.php?id=5\">Delete</a>"; 

}
 }
 }

What are the different ways you can keep a User "logged in"?

From what I *vaguely* recall from a year or two ago when I read a whole hoard of PHP books, you commonly use cookies and sessions.

But I'm asking this more from an OOP standpoint than a PHP standpoint.

Let's say I have a User record in my database, and a User comes along and attempts to log in.

In OOP terms, I would think you'd call some class to help log them in, and upon successfully logging in, you would "load" the User object into memory and set the "LoggedIn" field to "True". Then as long as that field was set in their object, they could surf all over the place and do things like change their account and buy things.

Is that how you would do it in OOP?

Sites such as this one often show the logged on users and guests.     I have no reason to need to do so, but am curious on how this is accomplished.   For users, yes, you've authenticated them and logged them on regardless of IP address, but how do you know they didn't just close their browser?   For guests, are they just using IP address?  And still, how do you know when they leave?   PS.  How should I include an image in a post like I did?  What I did was first attach a file, and then edit the post to include that file as an image.  Couldn't seem to include an image off my local PC.  Not a better way?

Hi all,

Does anyone know of an effective way of find out whether a user is still logged in and they haven't left?

Please help with my register page: http://www.retroandvintage.co.uk/register.php

after someone has registered they are stuck on reg_script.php and don't get redirected back to main.php being already logged in?!

'password' fields are checked to ensure they are of the correct format and length.
If there are any problems here an error is added to the $messages array and
then the script executes the 'doIndex()' function - this function basically
outputs the main 'index' page for this script - ie the login form.

If there are no problems with the previous step, the 'login' and 'password'
field data is passed to the 'checkPass' function to check that an entry
exists in the 'users' table for that login/password pair.
If nothing is returned from the 'checkPass()' function, an error is
added to the $messages array and the 'doIndex()' function is called as above.

If a row of data is returned from the 'users' table, the data is passed to
the 'cleanMemberSession()' function - which initializes session variables and
logs the user in.  The user is then forwarded to the members page.

If the form hasn't yet been submitted, then the 'doIndex()' function is called
and the login page is displayed.

I have an issue I am not sure how to solve.  What I want to do is to make sure authentication has already occurred .  Or that my $currentMember is set and it if is set for an IF statement to do nothing..  However it it is not set for a redirect to the home page with no echo statements or anything to that nature just a redirect. Am I even close?

Code: [Select]
<?php


include( ABSOLUTE_PATH . 'class/database.class.php' );
include( ABSOLUTE_PATH . 'class/person.class.php' );

//Start Session
session_start();

$currentMember = unserialize($_SESSION['currentMember']);

$db = new Database;
$person = new Person($currentMember->memberid);


if ( $auth_satus == 0 ) {
header('Location:' . APP_ROOT . 'index.php');
}

exit();

?>

             

 i need to display the  fullname and email of the logged in user.

<?php
session_start();
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("db_register") or die(mysql_error());
$query = "SELECT` fullname`, `email` FROM `members` WHERE `username`='".$_SESSION['user']."' LIMIT 1";
if($doQuery = mysql_query($query)) {
    if(mysql_num_rows($doQuery)) {
      $user = mysql_fetch_assoc($doQuery);
      print_r($user);
    } else {
      echo 'No result returned for the query: '.$query;
    }
  } else {
    echo 'The following query failed: '.$query;
  }
$id = $user['id'];
$fullname = $user['fullname'];
$email = $user['email'];
}
?>
<br>
Fullname : <?php echo $fullname; ?>
<br>
Email : <? echo $email; ?>
?>


HELP please .

This will be a little difficult to explain, but keep with me.
On the profile.php page. It starts a new session.
Code: [Select]
// Connect to MySQL...
$conn = mysql_connect($hostname, $username, $password)      or die("Connecting to MySQL failed"); 
mysql_select_db($database, $conn)     or die("Selecting MySQL database failed");

// Run our query, see if session username exists in session field...
$sql="select username,email from user where username='{$_SESSION['user']}' limit 1";
$result=mysql_query($sql,$conn);
// Parse our results into $data (as an associative array)...
$data=mysql_fetch_assoc($result);

// If one row was found in the result set, username exists...
if (mysql_num_rows($result)==1) {
$_SESSION['sellername'] = $data['username'];
So what I am hoping that is doing, is the session named "sellername" is stored with the variable of the logged in user. In this example "testuser".
Now the page updates.php will have an id attached to like so: updates.php?id=13. Which will have info only available for testuser's eyes. On the page it does this.
Code: [Select]
// Connect to MySQL...
$conn = mysql_connect($hostname, $username, $password)      or die("Connecting to MySQL failed"); 
mysql_select_db($database, $conn)     or die("Selecting MySQL database failed");
// Run our query, see if session username exists in session field...
$sql="select username from user where username='{$_SESSION['user']}' limit 1";
$result=mysql_query($sql,$conn);
// Parse our results into $data (as an associative array)...
$data=mysql_fetch_assoc($result);

// If one row was found in the result set, username exists...
if (mysql_num_rows($result)==1) {
$query='select seller from listings where seller = "'.$data['username'].'"';
$queryresult=mysql_query($query,$conn);
while($info = mysql_fetch_assoc($queryresult)){
if ( $_SESSION['sellername'] == $info['seller'] ){
The if statement should process: "If the session variable for 'sellername' equals the database entry 'seller' then display the rest of the page."
However, no matter what user is logged, it will display the page. Any ideas?
