  1. Thank you for the update Larry. I could only imagine how resource consuming, writing programming books can be. Your books are the best for my learning style, so whenever you drop another book, I'll be buying, without hesitation.
  2. Hello Larry, Has there been any new developments in regards to a new edition of this book? I hope you have been well during these trying times.
  3. Silly me it only needed the PASSWORD_DEFAULT constant as it's second parameter. All is well that ends well, lol. Hopefully anyone having issues with this little problem will find this helpful
  4. So I have everything up and running and I have modified the login app to my personal needs. That being said, it seems that the conditional that requires the password_hash() function only has a solution created from the variable that creates a random string, leaving the password_hash() function with only one parameter, the $p variable: if ($uid) { // If everything's OK. // Create a new, random password: $p = substr(md5(uniqid(rand(), true)), 3, 15); $ph = password_hash($p); // Update the database: $q = "UPDATE users SET pass='$ph' WHERE user_id=$uid LIMIT 1"; $r = mysqli_query($dbc, $q) or trigger_error("Query: $q\n<br>MySQL Error: " . mysqli_error($dbc)); if (mysqli_affected_rows($dbc) == 1) { // If it ran OK. // Send an email: $body = "Your password to log into <whatever site> has been temporarily changed to '$p'. Please log in using this password and this email address. Then you may change your password to something more familiar."; mail($_POST['email'], 'Your temporary password.', $body, 'From: admin@sitename.com'); // Print a message and wrap up: echo '<h3>Your password has been changed. You will receive the new, temporary password at the email address with which you registered. Once you have logged in with this password, you may change it by clicking on the "Change Password" link.</h3>'; mysqli_close($dbc); include('../../../PHP and MySQL - For Dynamic Sites - 5th/ch18/html/includes/footer.html'); exit(); // Stop the script. } else { // If it did not run OK. echo '<p class="error">Your password could not be changed due to a system error. We apologize for any inconvenience.</p>'; } } else { // Failed the validation test. echo '<p class="error">Please try again.</p>'; } mysqli_close($dbc); } // End of the main Submit conditional. This created the following email error message to be delivered: An error occured in script 'C:\xampp\htdocs\LocalServer\larry_ullman_php\login_ex\forgot_password.php' on line 45: password_hash() expects at least 2 parameters, 1 given Date/Time:9-4-18 09:29:14 The temporary password email is mailed as is should, the problem being that because the password_hash() function created an error the random string isn't stored in the database and the password column is wiped clean, leaving no further option for logging in with the new password. I have begun searching for a solution using multiple queries and the list() function but the code example is apparently flawed and as is will never function properly.
  5. I want to start off by saying I've learned more from your series of books than any other source on the market to date. That being said I am stumped with the user activation email using script 18.7. The user is registered just fine and the email it sends to the proper email, but when I click the link all I get is Object not found: error. I have no clue what to do from here I've gone over the code countless times and I have absolutely no answer. this is my activate.php: <?php require('includes/config.inc.php'); $page_title = 'Activate Account'; include('includes/header.php'); ?> <?php if(isset($_GET['x'], $_GET['y']) && filter_var($_GET['x'], FILTER_VALIDATE_EMAIL) && (strlen($_GET['y']) == 32)){ require(MYSQL); $q = "update users set active=null where (email='".mysqli_real_escape_string($dbc, $_GET['x']). "' and active='" . mysqli_real_escape_string($dbc, $_GET['y']) . "') limit 1"; $r = mysqli_query($dbc, $q) or trigger_error("Query $q\n<br>MySQL Error: " . mysqli_error($dbc)); if(mysqli_affected_rows($dbc) == 1){ echo "<h3>Your account is now active. You may now log in.</h3>"; }else{ echo '<p class="text-danger">You acount could not be activated. Please re-check the link or contact the system administrator.</p>'; } mysqli_close($dbc); }else{ $url = BASE_URL .'index.php'; ob_end_clean(); header("Location: $url"); exit(); } ?> <?php include('includes/footer.php')?>
