HI people,

After abit of help with a website i need to create for assignment, not very good on php but getting there, any help would be welcome.

One of my tasks is that a user who logs in can swicth database from MySQL to SQLite, here is my code, just wondering where im going wrong as getting the following error

Fatal error: Call to a member function getProperty() on a non-object in C:\xampp\htdocs\Brookxml\switchdb.php on line 32

Here is the code i currently have for that page -

<?php
// Start login Session
session_start();
?>

<?php
require ('includes/header.php');
?>

<?php
$page_title = 'Change Database';
?>
<strong><h1>Welcome to BrookXML</h1></strong>
<br />
<h2><?php echo "$page_title"?></h2>

<form action="" method="post" value="change">
	<p>Please select which Database you would like to use:</p>
	<p>MySQL:<input type="radio" name="dbtype" value="MySQL" /></p>
	<p>SQLite:<input type="radio" name="dbtype" value="SQLite" /></p>
	<p><input type="submit" name="change" value="Change DB" /></p>
</form>

<?php

 //code for switching

if (ISSET($_POST[change])){
	$session->setProperty('dbType',$_POST[radio]);//change the database type to that selected
}
else{//if change was not selected, get the dbType from sessions
	$db = $session->getProperty('dbType');//retrieve the database type
if ($db == ""){//if no DB has been selected yet, assume MySQL and store in sessions
	$db = "mysql";
	$session->setProperty('dbType',$db);
	return "";
}
}
?>

<?php
require ('includes/footer.html');
?>

Nowhere in the supplied code do you instantiate $session, so unless it's instantiated in the include file, that's what I'd expect to happen. Without knowing for sure what is intended and what session class you meant to use (if any), I'm not sure what else to tell you.

As NogDog said, you need to show the PHP code you have in the header.php file, as that is where the $session object variable should be created as it isn't in your above code.
