I am having an issue in which, sometimes, mostly in Firefox, that a user needs to login twice for the actual php session data to work. IE8 usually works without issues, but I can't say 100% error free.

 

Validating the User

<?php
session_start();  // Start Session

include 'db.php';

// Convert variables
$pilotid = $_POST['pilotid'];
$password = $_POST['password'];
$encryptpassword = md5($_POST['password']);

if((!$_POST['pilotid']) || (!$_POST['password'])){
echo "Please enter ALL of the information! <br />";
exit();
}

// check if the user info validates the db
$sql = mysql_query("SELECT * FROM users WHERE pilotid='$pilotid' AND password='$encryptpassword'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
while($row = mysql_fetch_array($sql)){
foreach( $row AS $key => $val ){
	$$key = stripslashes( $val );
}

   if($row['admin'] == 'Y'){
                

	// Register some session variables!
	session_register('pilotid');
	session_register('admin');

	$_SESSION['pilotid'] = $pilotid;
	$_SESSION['admin'] = 'true';

	header("Location: crewroom.php");
}
else if($row['admin'] == 'N'){
session_register('pilotid');

$_SESSION['pilotid'] = $pilotid;

header("Location: crewroom.php");
}
} 
}else{
echo "You could not be logged in! Either the username and password do not match or you are not registered!<br />
Please try again!<br />";
}
mysql_close($connection);
?>

 

The page where the session seems to work after only logging in twice.

<?php
session_start();
include "db.php";

$flight = $_GET['number'];
$section = $_GET['section'];
$pilotnum = $_GET['pilotnum'];

echo $pilotid;
?>

<?php
if(isset($pilotid)){

?>
<center>
<input type="submit" name="Submit" value="Submit Bid">
</center>




<?
}
?>

 

The issue is that Submit Button doesn't always show up. Any ideas?

You cannot just put a submit button/form element on a page unless it is inside of a valid form, though some forgiving browsers might ignore that error and allow it to function and submit back to the same page.

 

Your code is also using session_register(), which was depreciated long ago (7 years ago in fact) and cannot actually be used at the same time that you use $_SESSION variables. Since you are using the correct $_SESSION variables, remove all the code using session_register().

The submit button is in a valid form, I just didn't put all of the html code in the code snippet on here.

Cannot really help you with your code when you do things like that and you don't mention that the code has been altered for the post. It just wastes everyone's time.

Ok. Here's the whole code for that page, to clear up any misunderstandings.

 

<?php
session_start();
include "db.php";

$flight = $_GET['number'];
$section = $_GET['section'];
$pilotnum = $_GET['pilotnum'];

echo $pilotid;
?>
