I need to make an error message appear if a user inputs an invalid username/password but the error message now displays whenever I open the program, even before I type anything in?
Here’s my code
[php]<?php
session_start();
ob_start(); // begin buffering the output
?>
<?php $un = $_POST['username']; $pw = $_POST['password']; // Server Connection variables $host = 'localhost'; $user = 'root'; $passwd = ''; $database = 'program3'; $table_name = 'user_passwords'; $qry1 = "Select * from $table_name where username = '$un' AND password = '$pw'"; $connect = mysql_connect($host, $user, $passwd); if (!$connect) { die ("Cannot connect to the $server using $user"); } else { // Select the database mysql_select_db($database, $connect); } if (session_id() == $_SESSION["sid"]) { $result = mysql_query($qry1, $connect) or die(mysql_error()); $row = mysql_fetch_array($result); if ($un = $row['username'] && $pw = $row['password']) {print "Welcome, you have successfully made it to the Julian Date Calculator";} else { $_SESSION["form2error"]= "Invalid Username and/or Password"; header('location: sessions_input.php'); } } else { $_SESSION["form2error"]= "Please enter a valid username and password before proceeding to screen 2"; header('location: sessions_input.php'); } ob_end_flush(); // output the data in the buffer ?>
