  1. Hi Larry, Hope you are well. If I am on the 'checkout.php' page, and then I go directly to the 'login.inc.php' page from the 'checkout.php' page, after I successfully log in, I want to go straight back to the 'checkout.php' page. I want to go directly back to the checkout.php from the 'login.inc.php' page, only after initially coming from the 'checkout.php page', and not from any other page. So whatever page I am on, and I go directly to the 'login.inc.php' from that page, I want to be redirected straight back to the previous page. I have tried to implement this, but I am not having much luck. PS: I am trying to include the login feature from exercise 1. Thank you. regards
  2. Hi Larry, I copied your code line to line, and the only reference is in the billing.js file on line 16 var cc_number = $('#cc_number').val(), Also, it's in the billing_stripe.html form <div class="field"><label for="cc_number"><strong>Card Number</strong></label><br /><input type="text" id="cc_number" autocomplete="off" /></div> Other than that, I can't see it defined anywhere else. QU: Do I need to define the variable 'cc_number' again somewhere else, because I literally copied your entire code and assumed everything is fine, so I am reluctant to change anything. I have run out of ideas regards
  3. Hi Larry, I am having a few problems regarding the 'billing_stripe.php' file. I wrote the code below that's in my 'billing_stripe.php' file. When I get to the line: $cc_last_four = substr($cc_number, -4); An error is thrown up and it says: 'Undefined variable: cc_number'. I have tried everything but I can't seem to find out why it's saying that the cc_number variable is undefined. Qu 1: Do you have any suggestions as to what might be the problem? Qu 2: Is the code in the billing_stripe.php file below correct, or do I need to take out some sections? Code for 'billing_stripe.php' file <?php // This file is the second step in the checkout process. // It takes and validates the billing information. // This updated versions uses Stripe. // This script is created in Chapter 15. // Require the configuration before any PHP code: require('./includes/config.inc.php'); // Start the session: session_start(); // The session ID is the user's cart ID: $uid = session_id(); // Check that this is valid: if (!isset($_SESSION['customer_id'])) { // Redirect the user. $location = 'https://' .

  4. Hi Larry, I sorted the problem. Please ignore the previous posts. Thank you!
  5. Note: For some reason, the lines are getting spaced out Hi Larry, I made a slight adjustment in the checkout.php file. I simply moved the session_id($uid) and session_start() lines to the top of the page, and it works. I can now go straight to the checkout.php page without it giving me the error 'session_id(): Cannot change session id when headers already sent' For example on the checkout.php page I commented out the session_id($uid) and session_start() lines, and just put them right at the start of the checkout.php page on page 297 as follows: <?php session_id($uid); session_start(); require('./includes/config.inc.php'); // Check for the user's session ID, to retrieve the cart contents: if ($_SERVER['REQUEST_METHOD'] === 'GET') { if (isset($_COOKIE['SESSION']) && (strlen($_COOKIE['SESSION']) === 32)) { $uid = $_COOKIE['SESSION']; // Use the existing user ID: //session_id($uid); // Start the session: //session_start(); } else { // Redirect the user. $location = 'http://' . BASE_URL . 'cart.php'; header("Location: $location"); exit(); } } else { // POST request. session_start(); $uid = session_id(); } Qu 1: Can I leave it like this, or won't this work? Qu 2: Based on what I just did, what do you think could be the problem? It seems the problem starts after the require('./includes/config.inc.php') line. If I could just simply put the code at the top of the page, this would solve the problem, but I don't know if this is allowed. Also, I would like to find out why the original code in the checkout.php page stops working and throws out the error message: session_id(): Cannot change session id when headers already sent' regards
  6. I will try out your suggestions and let you know how far I have got to. Appreciate that Larry! Thank you!
  7. Hi Larry, I put the website online on a hosting server with a few html design alterations. It works fine up until when I try and get onto the checkout.php page. It gives me the following error: 'checkout.php' on line 10: session_id(): Cannot change session id when headers already sent' I removed all the ?> tags from the all .php files. I have spent two whole days trying to find out what the problem is, but nothing. The problem occurs when I get to the line session_id($uid); on the 'checkout.php' page on page 297. If I remove the lines: session_id($uid); session_start(); in the checkout.php on page 297, I then get access to the 'checkout.php' page. For some reason, the session_id($uid); and session_start() lines are the problematic lines. Can you suggest what it could be, and what I could do to fix the problem. Thank you regards
  8. Hi Larry, Hope you are well. Qu 1: wanted to know, how would I change the price of a product based on the different sizes? So if a customer goes to the product details page for a product, it would have all the different size options. The product would have a default option with a default size. If the customer clicked on the small size the price would change according to that size. Similarly a price change for sizes medium and large. I could then add that size and price to the shopping cart. Qu 2: And lastly how would I allow the user to select different colors for the product, and be able to add that color product to the database? I could then add that color for that product to the shopping cart Thanks in advance
  9. Qu 1: What I mean, is zend mail secure and efficient enough to be used as a professional email sender in a fully functional ecommerce website? Qu 2: if zend mail is not meant for a professional environment or not secure enough, what professional email sender would you recommend? regards
  10. Ok, that's fine. So would I be able to use the zend mail in a production environment? Meaning, if I upload the whole application to my hosting provider, will i be able to use their smtp/email settings along with the zend mail code you wrote, to implement sending emails using zend mail?
  11. Hi Larry, Happy New Year! I'm having problems sending and receiving emails via the zend-mail procedure. The code on page 434 runs fine without any errors, but I am just not receiving any emails. I used the exact code on page 434, but that wasn't working, so I tried to configure smtp settings, thinking that may be the missing solution, which is: // Create a new mail: use Zend\Mail; use Zend\Mime\Message as MimeMessage; use Zend\Mime\Part as MimePart; use Zend\Mail\Transport\Smtp as SmtpTransport; use Zend\Mail\Transport\SmtpOptions; // Create the parts: $html = new MimePart($body_html); $html->type = "text/html"; $plain = new MimePart($body_plain); $plain->type = "text/plain"; // Create the message: $body = new MimeMessage(); $body->setParts(array($plain, $html)); // Establish the email parameters: $mail = new Mail\Message(); $mail->setFrom('myemaill@aol.com', 'Dmx'); $mail->addTo($_SESSION['email'], 'Tom'); $mail->setSubject("Order #{$_SESSION['order_id']} at the Coffee Site"); $mail->setEncoding("UTF-8"); $mail->setBody($body); $mail->getHeaders()->get('content-type')->setType('multipart/alternative'); // Setup SMTP transport using LOGIN authentication $transport = new SmtpTransport(); $options = new SmtpOptions(array( 'name' => 'localhost', 'host' => 'localhost', 'connection_class' => 'login', 'connection_config' => array( 'username' => 'myusername', 'password' => 'mypassword', ), )); $transport->setOptions($options); $transport->send($mail); The above code then gave me the following error: 'An error occurred in script '/Applications/MAMP/htdocs/vendor/zendframework/zend-mail/src/Protocol/AbstractProtocol.php' on line 223: stream_socket_client(): unable to connect to tcp://localhost:25 (Connection refused)' So I'm at a loss as to what to do now. I know the zend-mail code has changed a lot since you wrote the book, but I just can't seem to find any success in finding the correct code needed to send and receive emails. Qu: Please could you help, by giving me the correct code needed to send emails using zend-email. I'm using a mac and mamp. Thank you regards
  12. Hi Larry, On page 344, in the 'tip' section, you wrote that in the forum there is a way on how to add general coffee and goodie types. I searched the forum, but cannot find the solution. Qu 1: Could you possibly send me the scripts for both solutions or direct me exactly to where I can the solution please. Thank you. regards
  13. Hi Larry, Seasons greetings to you. Hope you had a good one. Problem 1 Regarding the site administration section with the following url: localhost/admin/ When I click on the 'customers' link on the horizontal menu in the admin section, the 'customers.php' page doesn't exist. It just goes to the following url: localhost/admin/# I have looked and I can't find the 'customers.php' page. Qu 1: Can you let me know where I can find the 'customers.php' and script, in order to make the above link work and produce the correct results. Problem 2 When I click on the 'orders' link in the horizontal menu, in the admin section, in order to view the orders, and then click on the 'customer name' link to view the customer who made the order, I am sent to the following link, and then presented with the following error message: localhost/admin/view_customer.php?cid=58 'Not found. The requested URL was not found on this server.' Again, there is no 'view_customer.php' in any of the folders. Qu 2: Can you let me know where I can find the 'views_customers.php' in order to make the above link work, and produce the correct results. Thank you. regards
