Ok code:

 

Its suppose to query for data on the members.php page, store them as varaible using the extract() function, then echo them out later in the page into a table

 

Problem is i keep ending up with a blank HTML table with no data being echoed in it

 

 

checklogin.php

 

<?php
//Includes
include 'Libary/opendb.php';

//Get user posted info
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$encrypted_mypassword=md5($mypassword);

// To protect MySQL injection
$myusername = stripslashes($myusername);
$myusername = mysql_real_escape_string($myusername);

$sql="SELECT * FROM usersinfo WHERE Username='$myusername' AND Password='$mypassword'";
$result=mysql_query($sql) or die(mysql_error());

// Mysql_num_row is counting rows returned
$count=mysql_num_rows($result) or die(mysql_error());  ;

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "members.php"
session_start();
session_register("myusername");
session_register("mypassword");
$_SESSION['Username']=$myusername;
header("location:members.php");
}
else {
echo "Wrong Username or Password";
}
include 'Libary/closedb.php';
?>

 

members.php

 

<?php
error_reporting(E_ALL);  
//session name grab and page auth
session_start();
$usernamesession = $_SESSION['Username'];
if(!session_is_registered(myusername)){
header("location:index.html");
}

?>

//Main query for user info
$query  = "SELECT Username, Age, Sex, Location, Picture FROM usersinfo WHERE Username ='$usernamesession'";
$result = mysql_query($query) or die(mysql_error());  
//Place query data into variables
$row = mysql_fetch_array($result) or die(mysql_error());
extract($row, EXTR_PREFIX_SAME, "prefix123");  
?>

    <td><?php echo $Location; ?> </td>
  </tr>
</table>
<?php
include 'Libary/closedb.php';
?>
<p> </p>
</body>
</html>

 

opendb.php

 

<?php
$conn = mysql_connect("localhost", "testdatabase", "test") or die(mysql_error());
echo "Connected to MySQL<br />";
mysql_select_db("testdatabase") or die(mysql_error());
echo "Connected to Database<br />";
?>

 

closedb.php

 

<?php
mysql_close($conn) or die(mysql_error());
echo "<p><b>Database Closed</b>";
?>

I think you should change this

<?php
error_reporting(E_ALL);  
//session name grab and page auth
session_start();
$usernamesession = $_SESSION['Username'];
if(!session_is_registered(myusername)){
header("location:index.html");
}

?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Members Page</title>
<style type="text/css">
<!--

background-color: #666666;
}

</style></head>

<body>
<p>
<?php
//Includes
include 'Libary/opendb.php';


//Main query for user info
$query  = "SELECT Username, Age, Sex, Location, Picture FROM usersinfo WHERE Username ='$usernamesession'";
$result = mysql_query($query) or die(mysql_error());  
//Place query data into variables
$row = mysql_fetch_assoc($result) or die(mysql_error()); //changed//
extract($row, EXTR_PREFIX_SAME, "prefix123");  
?>
</p>
<table width="257" border="1">
  <tr>
    <td colspan="2"><img src="<?php echo $Picture; ?>"/></td>
  </tr>
  <tr>
    <td width="133">Username</td>
    <td width="108"><?php echo $row['Username']; ?> </td><!-- This should echo out like this, and not a variable like before as the variable wasn't set-->
  </tr>
  <tr>
    <td>Age:</td>
    <td><?php echo $Age; ?> </td>
  </tr>
  <tr>
    <td>Sex:</td>
    <td><?php echo $Sex; ?> </td>
  </tr>
  <tr>
    <td>Location:</td>
    <td><?php echo $Location; ?> </td>
  </tr>
</table>
<?php
include 'Libary/closedb.php';
?>
