Sessions

[corruption]

I'm trying to finish creating my members only area on my fraternity website. I need to check on each page if the person is logged in. The code i currently have doesn't seem to be working.

<?php
//phonelist for brothers

include '../connect.php';
//check for session start.
if((isset( $_SESSION['fname'] )) || (isset($_SESSION['lname'])))
{
  echo 'Welcome $first_name." ".$last_name';
  header('location: brothers.php');
  }
  else
  {
  echo 'This is a brothers only area please login first.';
  }

I want it to check for both the registered sessions of first_name and last_name. They are registered on the login form processing page.

try using http://www.php.net/array_key_exists

[corruption]

<?php
$session_array = array("first" => 1, "second" => 4);
if (array_key_exists("first", $search_array)) {
   echo "The 'first' element is in the array";
}
?> 

i guess i don't really understand it.

i figure i should be able to use sessions

but i'll try this..

<?php
$session_array = array("first" => fname, "second" => lname, "third" => id);

if (array_key_exists ("first", $session_array)); {
echo 'welcome $fname." ".$lname';
}

?>

that's what i think i should do. but i'm not realy sure, kinda new to something that in depth.

$_SESSION is an array so try this

<?php
//phonelist for brothers

include '../connect.php';
//check for session start.
if(array_key_exists('fname', $_SESSION) && (array_key_exists('lname',$_SESSION)) {
   //this makes no sense you cannot echo and then send 
  //headers so I'll comment out the echo and see if that helps.
  //echo 'Welcome $first_name." ".$last_name';
    header('location: brothers.php');
} else {
    echo 'This is a brothers only area please login first.';
} //end if

that last set of code didn't function. Also with the sessions that i was using, i have some pages that do deny the visitor if not logged in and some that don't.

current edition

include '../connect.php';
session_start();

if(( isset( $_SESSION['fname'] )) || ( isset( $_SESSION['lname'])))
{
  echo 'Welcome'." ".$_SESSION['fname'];
  }
  else
  {
  header('location: index.html');
  }

I don't really know why the other pages don't work the same.

Also i'm not sure how the array_key_exists works

first try print_r($_SESSION) to see that you have. Then change logic. Do small script to redirect user away if user is not logged and pass it if logged. And use this script on every page of private area:

require_once 'pass.inc.php';
// Welcome user...

[corruption]

when i try the print_r($_SESSION)
i get a blank page...

here's the code...
<?php
// check the session
session_start());
print_r($_SESSION);
?>

I'm not sure why it doesn't recognize the session. Here's where the session is started...

$sql = mysql_query("SELECT * FROM brothers WHERE number='$number' AND password='$password'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
	while($row = mysql_fetch_array($sql)){
	foreach( $row AS $key => $val ){
		$$key = stripslashes( $val );
	}
		// Register some session variables!
		session_register('fname');
		$_SESSION['fname'] = $fname;
		session_register('lname');
		$_SESSION['lname'] = $lname;
		session_register('id');
		$_SESSION['id'] = $id;
