    Script 11.4 - Error 404 Upon Opening New Window

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    The root folder is this:

     

    C:\xampp\htdocs

     

    Originally, I had my temporary files stored in the default folder; but, like I said, I set two temp file folders up inside my directory.  The first one is:

     

    C:\xampp\htdocs\phpmysql\php-work\uploads

     

    The second one is the one I have listed in the previous post:

     

    C:\xampp\htdocs\phpmysql\php-work\ch11\uploads

     

    I keep going back and forth between folders and, for some reason, I'm still not getting the picture to display.

     

    Does this help?

    Script 11.4 - Error 404 Upon Opening New Window

    in PHP and MySQL for Dynamic Web Sites: Visual QuickPro Guide (4th Edition)

    Posted

    Good Afternoon!

     

    I'm having trouble executing Script 11.4 in Chapter 11.  The code for Script 11.2 reads:

    <?php  #  Script 11.2 - upload-image.php
     
    // Check if the form has been submitted:
    if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Check for an uploaded file:
    if (isset($_FILES['upload'])) {
    // Validate the type.  Should be JPEG or PNG.
    $allowed = array ('image/pjpeg', 'image/jpeg', 'image/JPG','image/X-PNG', 'image/PNG', 'image/png', 'image/x-png');
    if (in_array($_FILES['upload']['type'], $allowed)) {
    // Move the file over.
    if(move_uploaded_file($_FILES['upload']['tmp_name'], "../uploads/{$_FILES['upload']['name']}")) {
    echo '<p><em>The file has been uploaded!</em></p>';
    } // End of move IF.
    else {
    // Invalid type
    echo '<p class="error">Please upload a JPEG or PNG image.</p>';
    }
    } // End of isset($_FILES['upload'] IF.
     
    // Check for an error:
    if ($_FILES['upload']['error'] > 0) {
    echo '<p class="error">The file could not be uploaded because: <strong>';
     
    // Print a message based upon the error.
    switch($_FILES['upload']['error']) {
    case 1:
    print 'The file exceeds the upload_max_file size setting in php.ini.';
    break;
    case 2:
    print 'The file exceeds the MAX_FILE_SIZE setting in the HTML form.';
    break;
    case 3:
    print 'The file was only partially uploaded.';
    break;
    case 4:
    print 'No file was uploaded.';
    break;
    case 6:
    print 'No temporary folder was available.';
    break;
    case 7:
    print 'Unable to write to the disk.';
    break;
    case 8:
    print 'File upload stopped.';
    break;
    default:
    print 'A system error occured.';
    break;
    } // End of error IF.
     
    // Delete the file as if it still exists:
    if (file_exists($_FILES['upload']['tmp_name']) && is_file($_FILES['upload']['tmp_name']) )
    {
    uplink($_FILES['upload']['tmp_name']);
    }
     
    } // End of the submitted conditional
    }
    }
     
    ?>
     
    This is my Script 11.3:
     
    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 to 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 popup window:
    popup = window.open(url, "ImageWindow", specs);
    popup.focus();
    }
     
    Finally, this is Script 11.4:
     
    <?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.
    ?>
     
    The problem is, when I click on any of the image links in Script 11.4, it shows a "Error 404 - File Not Found" message instead of the picture itself.  It also says something about the directory being "wrong or outdated".  I have not been able to fix this error, regardless of what I do.
     
    Could you give me any pointers as to what might be wrong?  Thanks!
