include('$file');

Hi
Can I do this:
$file="articledetails.php";
include('$file');
I really need it or something similar to make my pages more dynamic

 

variables won't be parsed between single quotes.

include($file);

PHP:

 

solved! thanks

 

You can also use like this: include("$file");

 

now i'm using this code as the next step:

function membersOnly() {
        error_reporting(E_ALL);
        ini_set('display_errors', true);
       
        if (!$_SESSION['logged']) {
                $_SESSION['log_to'] = $_SERVER['REQUEST_URI'];
                session_write_close();
            {   $file="login.php";
                 header('Location: message.php'); }
                die();
        }
}

PHP:

and message.php has the following code on line 67:

<?  include "$file"; ?>

PHP:

now it is redircted to message.php but the login form is not shown in it. instead it prompts:
Notice: Undefined variable: file in g:\programs(2)\easyphp1-8\www\ha\previous\new folder\htdocs\message.php on line 67

Warning: main(): Failed opening '' for inclusion (include_path='.;G:/Programs(2)/EasyPHP1-8\php\pear\') in g:\programs(2)\easyphp1-8\www\ha\previous\new folder\htdocs\message.php on line 67

 

Once you have moved page $file will have not be defined.

store the value of $file in a session variable or include it at the end of your message. You might need to call session_start depending upon your setup e.g.

in function membersOnly() add

session_start(); 
$_SESSION['file'] = "login.php"; 

PHP:

and in message.php

<?  include "$_SESSION['file']"; ?>

PHP:

although I'm not sure if you can include a session variable you might need to put it into a local variable first e.g.

<? 
$file=$_SESSION['file']
include "$file";
?>

PHP:

 

You can include files in session variables. But your example would throw a parse error. Just remove the double quotes or put the variable between curly brackets.

 

thanks for your reply
I tried it now but it seem it's not working. it prompts:
Notice: Undefined variable: _SESSION in g:\programs(2)\easyphp1-8\www\ha\previous\new folder\htdocs\message.php on line 67

Warning: main(): Failed opening '' for inclusion (include_path='.;G:/Programs(2)/EasyPHP1-8\php\pear\') in g:\programs(2)\easyphp1-8\www\ha\previous\new folder\htdocs\message.php on line 67

 

that threw a parse error too. someone suggested I use include instead of redirect. i'm gonna try it

 

You need to add session_start() at the top of your page to access $_SESSION variables.

And both ways I said would work.

include "{$_SESSION['file']}";
// Or
include $_SESSION['file'];

Hi
this code solved it:

function membersOnly() {
        error_reporting(E_ALL);
        ini_set('display_errors', true);
       
        if (!$_SESSION['logged']) {
                $_SESSION['log_to'] = $_SERVER['REQUEST_URI'];
                session_write_close();
            session_start(); 
                $_SESSION['file'] = "login.php";
                include 'message.php';
                            die();
        }
}

PHP:

and in message.php:

<?  include $_SESSION['file']; ?>

PHP:

it shows the login form now. but it prompts another error upon login:
Fatal error: Call to a member function on a non-object in g:\programs(2)\easyphp1-8\www\ha\previous\new folder\htdocs\login.php on line 36
this error does not occur when I use login.php alone for logging in.
line 36 begins as:

	if ($user->_checkLogin($processed['username'], $processed['password'], $remember)) {
			if (isset($_SESSION['log_to'])) {
				redirect($_SESSION['log_to']);
			} else {
				redirect('account.php/');
			}
		} else {
			failed($form);
		}

PHP:

 

by the way,
here:

$db = db_connect();
$user = new User($db);

PHP:

User is a class with over 260 lines. there, the function checklogin:

function _checkLogin($username, $password, $remember) {
		$md5pass = "'" . md5(substr($password, 1, -1)) . "'";
		$sql = "SELECT * FROM member WHERE " .
			"(username = $username) AND " .
			"(password = $md5pass) AND " .
			"(permission != '00-deny')";

		$result = $this->db->getRow($sql);

		if (is_object($result)) {
			$this->_setSession($result, $remember);
			return true;
		} else {
			$_SESSION['login']--;
			$this->_logout();
			return false;
		}
	}

Avoid using double quotes where you can.. They take longer to parse because everything is looked at, with single it is what it is.. nothing else needs to be done.
