[RESOLVED] Tracing URL

[sisira]

Hello,

I am a new personfor web development.

I am building a php used site supported by MySql.

I have given a ID (ex- http://www.aaaaa.com/1.php?recordID=1400) for people registered in the web site, where they can use that ID to promote my web.

ID is generated in MySql. I get the ID to MySQL using the codes
<?php echo $SERVER[HTTP_REFERER]; ?> and
<?php echo $SERVER[REQUEST_URI]; ?>
those codes work perfectly

But i am having a problem in tracking the ID. i want to pass the client ID from one page to another untill the ID is passed to the form where it (the ID) is submited to the Mysql data base
example

I know there are brainy ones who knows this is a very simple problem.
please can some body help me

Look into using sessions. This way the information stored in the session is kept accessible until the user closes the browser or until a defined expiry time is met.

[laserlight]

sisira, kindly do not cross post. I have deleted your duplicate posts and merged rsmith's reply to your thread in this Newbies forum.

[sisira]

thanks i am checking on session savings now.
sorry for the duplicate posts. want that happen again.
thanks

[sisira]

as you said i checked on geting the session on my web site. yes it works perfectly.

But again i cannot pass the Session variable through the login page, which is been given for my site visitors to login

can you please help me on this

thanks very much

sisira

Well my first thought is you wouldn't be able to set the session variable for the user ID until after they login. That being said the user would submit their username and password, your script would then compare the username and password submitted to the one stored in the db. The id would also be retrieved and if the user is successful at logging in you would set the session variable to the value of their id.

     //Get the submitted data.
           $username = mysql_real_escape_string($_POST['username']);
           $password= mysql_real_escape_string($_POST['password']);

 //Query the db.
       $query = "SELECT `id`, `username`, `password` from `users` WHERE `username` = '".$username."' AND `password` = '".$password."'";
       $result = mysql_query($query);

 //Check the result
      if(mysql_num_rows($result) <= 0){
           echo "Invalid username/password.";
      }else{
           $info = mysql_fetch_assoc($result); 
           $_SESSION['userID'] = $info['id'];

           header("Location: /redirect/to/wherever.php");
       }

Hope this helps. The id will now be available to all future scripts by calling $_SESSION['userID'] where necessary until the browser closes or an expiry time is reached.

[bpat1434]

Please note that [man]session_start/man MUST be called on all pages wishing to access (write or read) from the $_SESSION array. Otherwise you'll get an error or nothing 🙁 So at the beginning of all scripts dealing with session(s) you need session_start();, the one thing missing for rsmith's post.

[rsmith]

Ah yes. I always just put that into a header include file that gets included on every page so I don't have to type it. 😉

[bpat1434]

Ah, yes, I do that too; however, when posting on here, some users see the code and expect it to work as is, so it's best to either say they need to include it, or actually include it in the posted code 😉

[sisira]

thank both of you. i think i went wrong previously in trying to create a session ID before login. Now i will tink differenly.😉

thanks guys i will try again and tell you. it seems to go ok

[sisira]

sorry guys, still i am in trouble.

What i am actually trying to do is to give a URL parameter to (ex; ID=1250) to my site registered persons. so they can use that ID at the end of My home page URL and place it in their promotional campaigns. (ex- http://www.aaaaa.com/1.php?ID=1250) so if a sale is done from a person linking from that URL, i can identify it as a sale done by ID=1250.

All goes ok. i passed URL parameters to pages using ?ID=<?php echo $_POST['id1250']; ?> coding at the end of a link

(ex; <a href="../Login.php?id1250=<?php echo $_POST['id1250']; ?>">

Further I can take the URL to a data base too using <?php echo $SERVER[REQUEST_URI]; ?> and <?php echo $SERVER[HTTP_REFERER]; ?>

But i cant pass the URL parameter through a Login page .i use dreamweaver MX2004. In that the login form action re directs using
$MM_redirectLoginSuccess = "forms/Login all successfull.php";
$MM_redirectLoginFailed = "forms/Login all again.php";

to get the URL parameter to the end of the redirects i used
$MM_redirectLoginSuccess = "forms/Login all successfull.php?id1250=<?php echo $POST['id1250']; ?>";
$MM_redirectLoginFailed = "forms/Login all again.php?id1250=<?php echo $POST['id1250']; ?>";
those 2 dynamic redirect will not work. an eror message appers in the login page as,
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/content/b/a/t/battipanchi/html/another/Login.php on line 15

What can i do about this. still i am trying. sorry if i am bothering you too much

thanks guy

Bellow is the full coding of my Login page

<?php require_once('Connections/utf8_general_ci.php'); ?><?php
// *** Validate request to login to this site.
session_start();

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($accesscheck)) {
  $GLOBALS['PrevUrl'] = $accesscheck;
  session_register('PrevUrl');
}

if (isset($_POST['Username'])) {
  $loginUsername=$_POST['Username'];
  $password=$_POST['Password'];
  $MM_fldUserAuthorization = "accesslevel";
  $MM_redirectLoginSuccess = "forms/Login all successfull.php?id1250=<?php echo $_POST['id1250']; ?>";
  $MM_redirectLoginFailed = "forms/Login all again.php?id1250=<?php echo $_POST['id1250']; ?>";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_utf8_general_ci, $utf8_general_ci);

  $LoginRS__query=sprintf("SELECT Username, Password, accesslevel FROM Register WHERE Username='%s' AND Password='%s'",
  get_magic_quotes_gpc() ? $loginUsername : addslashes($loginUsername), get_magic_quotes_gpc() ? $password : addslashes($password)); 

  $LoginRS = mysql_query($LoginRS__query, $utf8_general_ci) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {

$loginStrGroup  = mysql_result($LoginRS,0,'accesslevel');

//declare two session variables and assign them
$GLOBALS['MM_Username'] = $loginUsername;
$GLOBALS['MM_UserGroup'] = $loginStrGroup;	      

//register the session variables
session_register("MM_Username");
session_register("MM_UserGroup");

if (isset($_SESSION['PrevUrl']) && false) {
  $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];	
}
header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}

Why would you put PHP in PHP? Just concatenate the string 😉

So your:

  $MM_redirectLoginSuccess = "forms/Login all successfull.php?id1250=<?php echo $_POST['id1250']; ?>";
  $MM_redirectLoginFailed = "forms/Login all again.php?id1250=<?php echo $_POST['id1250']; ?>";

becomes

  $MM_redirectLoginSuccess = "forms/Login all successfull.php?id1250=" . $_POST['id1250'];
  $MM_redirectLoginFailed = "forms/Login all again.php?id1250=" . $_POST['id1250'];

🙂 ya i was wrong in putting 2 php in the coding line. But i didnt know it was wrong since i have no knoledge in codings.

thank you very very very much

Now ID (URL Parameter) passes The login page.
So now the login page URL comes as
http://www.aaaa.com/Login.php?id1250=1500

And The page appers with no errors and lets a member pass the login page.

But now the problem is, the page redirected when the login is successful or wrong does not display the URL Parameter.
the redirect page apperes as,

http://www.directorylanka.com/forms/Login%20all%20successfull.php?id1250= or
http://www.directorylanka.com/forms/Login%20all%20again.php?id1250=

the Parameter (1500in my example) does not pass to the next page from the login page. what might be wrong now.

I know it could be a very simple matter, but i am unable to detect it.

Thank you very much
sisira

[bpat1434]

$POST is used with forms. Every page redirect, are you using forms to go through there? $GET is used to access items sent via the URL (like $GET['id1250'])... My guess is you want $GET['id1250'] when constructing URLs.

At this point, I'm going to ask, perhaps it would be better to look into sessions?

[sisira]

thanks you very much for the reply.

Yes, i changed from POST method to GET method (as you have told me). But still the URL parameter does not transfer from Login page to the redirect page. So i also think i will have to stop using URL Parameter and Will have to think about SESSION.

Does the SESSION work in the same way as URL parameter method. Can you please help me about how to start with SESSION and How to pass a ID given to a client through the SESSION.

thanks again
sisira

[bpat1434]

Sessions all start the same way: a call to [man]session_start/man at the top of the file(s) that will use sessions.

*Note: Not every file will need to call session_start. For example, if you include "config.php" inside of every file, you could either put session_start(); at the top of every file except config.php, in which case the session is available in config.php; or, you can put session_start() at top of config.php so that every page has access to the session. If you put session_start in config.php, you must make sure that nothing outputs to the browser before you include config.php.

So, if the user is supplying the "id" variable to only one place (your homepage url) and you don't expect it anywhere else (i.e. they can't use http://www.yourdomain.com/someotherpage.php?id=12345), then you'll do the assigning in your homepage url. I'd do something like this:

<?php
session_start();

if(isset($_GET['id']))
{
    $_SESSION['referrer'] = intval($_GET['id']);
}

Then, on every page after that that calls session_start() at the top, the $_SESSION['referrer'] will be available. So later on in say "order.php" if you wanted to let them know who they were referred by:

<?php
session_start();

echo 'You were referred by user id: ' . $_SESSION['referrer'];

Hope that helps.

[sisira]

i submited the following codes in a page and tested. but anerror saying Parse error: parse error, unexpected '<' in /aaaaa/test/page1.php on line 5. I think some basic coding in my page is wrong. Therefore the pages inserted with the coding you have given does not display. Sory for bothering you all the time. But please help me.

thanks
sisira

<?php
session_start();

if(isset($GET['hhh']))
{$SESSION['referrer'] = intval($_GET['hhh']);}

[bpat1434]

When you're mixing PHP and HTML, you either have to drop out of PHP entirely (with a closing "?>") or you need to echo / print the HTML.

So your code would best be:

<?php
session_start();

if(isset($_GET['hhh']))
{$_SESSION['referrer'] = intval($_GET['hhh']);}

?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</head>

<body>
<p>&nbsp;</p>
<p><a href="page1.php">1</a></p>

When PHP parses your file currently, it sees the first "<" of the Doctype declaration and doesn't know what it is, or why it's there. It's a comparison character, yet there's no left-handed comparison. So that's why it throws the syntax error.

[sisira]

🙂 hi,

How can i thnak you for all the help given. Finally it seems my problem with ID passing is over. I tested with the ID passing the login page. It worked well

Thank you so much. If it wasnt for you all i couldnt have solved my matter.

Thanks again and again.

I will tell my freinds also about PHPBuilder.com.

If any thing goes wrong again i will come contact again

SISIRA🙂
