Hierarchy

Khael

Hey,

Alright, here's the deal folks, I'm new to PHP so I don't know exactly how the hierarchy works with this language, but what I'd like to know is whether or not (and how) it were possible for a child file (since I'm not talking about classes here...) to access variables in it's mother file. Ok, yes, I'm aware that this probably makes no sense sine my terminology is class based (for Java and stuff).

So now that I've confused you, I'll try to explain what I'm trying to do:

/*Inside login.php*/
//The user has to log in putting in a username and password every time the file is run, but here I have just made the username equal to a string with my name.
$usrName="Khael";

/*Inside index.php*/
import 'login.php';
import 'stuff.php';

$pageContent=$stuff;
echo pageContent;

/*Inside stuff.php*/
$stuff = "
<html>
<head></head>
<body>

<table>
 <tr>
  <td>Blahahahaha posted by $usrName<td>
 </tr>
</table>

</body>
</html>";
//I need to get $usrName into this file without importing login.php, because I don't want to have to log in again.

If anybody has an idea, I'm all ears 😛

Thanks in advance,

Yeah,

PhP is pretty sloppy with vars. Only in functions and classes I think you lose the vars.

The import would be include(), require(), include_once() and require_once() .

Khael

It seems that if I were to use include() or require() the script would run me through the login process again.

I've been thinking, perhaps there is a way for me to send the login information to the login as well as another file. That way I can use include() on the other file without having to worry about logging in again.

Problem is, I have yet to find a way to submit a form to multiple locations. sigh If there only was a way....

Thx for all the help,

Hm..

OK. I am at a loss here.
- What does the import do?
- What is the login logic you are using?

Khael

The login works like this:

session_start(); 

$errorMessage = '';
if (isset($_POST['name']) && isset($_POST['pass'])) { 

$usrName=$_POST['name'];
$usrPass=$_POST['pass'];

include 'config.php';
include 'opendb.php';

// check if the user id and password combination exist in database 
$query = "SELECT user_id 
         FROM userTable 
         WHERE user_id = '$usrName' AND user_password = PASSWORD('$usrPass')"; 
$result = mysql_query($query) or die('Query failed. ' . mysql_error());
mysql_close();  

if (mysql_num_rows($result) == 1) { 
    // the user id and password match, 
    // set the session as logged in
    $_SESSION['db_is_logged_in'] = true;        
} else { 
	// or else display error message.
    $errorMessage = 'Sorry, wrong user id / password';
}
}

//if the user clicks on logout
if (isset($_POST['logout'])) { 
//unset the session to logged out.
   unset($_SESSION['db_is_logged_in']);
}

It is pretty much me using what I have learned in a bunch of login tutorials.

What I need is basically a way to temporarily store the username upon login, for flexible use by using the include() function in other files where I want the name displayed.

As it is, the username is only stored within the file with this login script, and any file that includes it. This means you would need to log in everywhere that this file is included, so it couldn't possibly be used for the purpose giving me the username wherever I want.

I hope that makes things a little more clear...=/

Thx,

You could set a session variable with the username?
(I'd seperate username and screen name though).

I usually set a user_id encrypted in a session, with my own decrypt. Very basic function, but enough to fool the casual observer.

Khael

Ok i think i understand what you are saying but im not sure how to go about doing that could you maybe post an example that i could take a look at, sorry to bother you like this its just i am new to php and im trying to work my way thru it =/

Thanks again

Eaxctly the way you do this:

$_SESSION['db_is_logged_in'] = true;

You could do, upon login:
$_SESSION['userid'] = $id ;

Currently, in your database, do you have an oauto_increment colum, which stores user numbers? You could store this number, maybe modified a bit if you are worried about hacking of the session (Which is at least tr\icky, I used the ASCII value of each indiivdual number, and seperate them with a seperatore, and transformed them by adding a certain string to to the ascii number. )

You can then when you need the username get this from the database,. based on id stored in the session.
