  1. Hi everyone. I've done everything I could think of to get Script 11.8 to work, but I keep getting the error message 'The username and password you entered do not match those on file'. The users.txt is where it should be (because it worked fine for register.php) and the script is almost exactly how it is in the book. I'm using the same user names and passwords as well. Is this happening because I'm on a Mac? Oh, I'm on PHP 5.3.6 and use XAMPP. <?php // Script 11.8 - login.php $file = '../users/users.txt'; if ($_SERVER['REQUEST_METHOD'] == 'POST') { // Handle the form. $loggedin = FALSE; // Not currently signed in. // Enable auto_detect_line settings: ini_set('auto_detect_line_endings', 1); // Open the file: $fp = fopen($file, 'rb'); // Loop through the file: while ( $line = fgetcsv($fp, 200, "\t") ) { // Check the file data against the submitted data: if ( ($line[0] == $_POST['username']) AND ($line[1] == md5(trim($_POST['password']))) ) { $loggedin = TRUE; // Correct username/password combination. // Stop looping through the file: break; } // End of IF. } // End of WHILE. fclose ($fp); // Close the file. // Print a message: if ($loggedin) { print '<p>You are now logged in.</p>'; } else { print '<p style="color: red;">The username and password you entered do not match those on file.</p>'; } } else { // Display the form. // Leave PHP and display the form: ?> <form action="login.php" method="post"> <p>Username: <input type="text" name="username" size="20" /></p> <p>Password: <input type="password" name="password" size="20" /></p> <input type="submit" name="submit" value="Login" /></form> <?php } // End of submission IF. ?> </body> </html>
  2. Hi everyone, I am really enjoying your book Larry, thanks. My problem is I am on the page where you use the header function and javascript to display the images from the uploads folder. I have one picture and for some reason when I click it, it does nothing. Would anyone care to look at my code or give me some hints as to why it is not working? I have tried the following: Compare my code to Larry's code Used Larry's code Enabled pop-ups Moved the javascript folder to a different location (a folder above and then changing the a href to ../javascript) images.php <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Images</title> <script type="text/javascript" charset="utf-8" src="js/function.js"></script> </head> <body> <p>Click on an image to view it in a separate window.</p> <ul> <?php # Script 11.4 - images.php // This script lists the images in the uploads directory. $dir = '../uploads'; // Define the directory to view. $files = scandir($dir); // Read all the images into an array. // Display each image caption as a link to the JavaScript function: foreach ($files as $image) { if (substr($image, 0, 1) != '.') { // Ignore anything starting with a period. // Get the image's size in pixels: $image_size = getimagesize ("$dir/$image"); // Make the image's name URL-safe: $image_name = urlencode($image); // Print the information: echo "<li><a href=\"javascript:create_window('$image_name',$image_size[0],$image_size[1])\">$image</a></li>\n"; } // End of the IF. } // End of the foreach loop. ?> </ul> </body> </html> function.js //Script 11.3 - function.js function create_window (image, width, height) { //Add some pixels to the width and height: width = width + 10; height = height + 10; //If the window is already open resize it ot the new dimensions if (window.popup && !window.popup.closed) { window.popup.resizeTo(width, height); } //Set the window properties: var specs = "location=no, scrollbars=no, menubars=no, toolbars=no, resizable=yes, left=0, top=0, width=" + width + ", height=" + height; //Set the URL: var url = "show_image.php?image=" + image; //Create the pop-up window: popup = window.open(url, "ImageWindow", specs); popup.focus(); } //End of function show_image.php <?php # Script 11.5 - show_image.php // This page displays an image. $name = FALSE; // Flag variable: // Check for an image name in the URL: if (isset($_GET['image'])) { // Make sure it has an image's extension: $ext = strtolower ( substr ($_GET['image'], -4)); if (($ext == '.jpg') OR ($ext == 'jpeg') OR ($ext == '.png')) { // Full image path: $image = "../uploads/{$_GET['image']}"; // Check that the image exists and is a file: if (file_exists ($image) && (is_file($image))) { // Set the name as this image: $name = $_GET['image']; } // End of file_exists() IF. } // End of $ext IF. } // End of isset($_GET['image']) IF. // If there was a problem, use the default image: if (!$name) { $image = 'images/unavailable.png'; $name = 'unavailable.png'; } // Get the image information: $info = getimagesize($image); $fs = filesize($image); // Send the content information: header ("Content-Type: {$info['mime']}\n"); header ("Content-Disposition: inline; filename=\"$name\"\n"); header ("Content-Length: $fs\n"); // Send the file: readfile ($image); here are how to folders are set up: xamp-->htdocs-->Learning-->(all php files) xamp-->htdocs-->Learning-->javascript-->function.js xamp-->htdocs-->uploads I also created an xampp-->uploads folder, but the files do not upload there and the scripts do not see the pictures in that folder. Thanks for everyone's help.......
