  1. By way of follow-up, I just moved on to 11.6 and now also get the following error message when I run Images.php: Warning: filesize(): stat failed for ../uploads/image in C:\Program Files\EasyPHP-DevServer-14.1VC11\data\localweb\scripts\Sept16\site\images.php on line 19 Agenda.png 0kb (26 October, 2016 17:16:53) I guess the two issues might be connected?
  2. OS: Windows 7 php version: 5.5.8 (running on EasyPHP Dev Server 14.1 VC11) Browser: Firefox 40.0.2 (same results in Chrome and IE) I am having problems with the show_image script in chapter 11. When I select an image from the list it opens a popup window of the appropriate size but with no image. In firefox I get the error message: 'The image ""cannot be displayed because it contains errors.' When I use the Web Developer menu to View Response Headers all is as expected except that it lists Content-Length: 0. I commented out the header calls and replaced them with echos: echo "Content-Type: {$info['mime']}</br>"; echo "Content-Disposition: inline; filename=\"$name\"</br>"; echo "Content-Length: $fs"; Which return the values you would expect: Content-Type: image/png Content-Disposition: inline; filename="Picture.png" Content-Length: 35880 I changed the Content-Disposition to attachment. The files download as normal with the appropriate file names but have a size of 0. When I try to open them I get the error message: "Windows Photo Viewer can't display this picture because the file is empty." I double checked the files in the upload folder and they are all normal .png files. My code is below. Any advice you can offer would be very gratefully received. Adam show_image.php <?php $name = FALSE; if (isset($_GET['image'])) { //echo 'Image set </br>'; $ext = strtolower(substr($_GET['image'], -4)); if (($ext == '.jpg') OR ($ext == 'jpeg') OR ($ext == '.png')) { //echo 'Correct ext </br>'; $image = "../uploads/{$_GET['image']}"; if (file_exists($image) && (is_file($image))) { //echo 'File exists </br>'; $name = $_GET['image']; } } } if (!$name) { //echo 'Unavailable'; $image = 'images/unavailable.png'; $name = 'unavailable.png'; } $info = getimagesize($image); $fs = filesize($image); header ("Content-Type: {$info['mime']}\n"); header ("Content-Disposition: inline; filename=\"$name\"\n"); header ("Content-Length: $fs"); //echo "Content-Type: {$info['mime']}</br>"; //echo "Content-Disposition: inline; filename=\"$name\"</br>"; //echo "Content-Length: $fs"; images.php <!DOCTYPE html PUBLIC "-//W3C// DTD XHTML 1.0 Transitional//EN" "http:/www.w3.org/TR/xhtml/DTD/xhtml1-transitional.dtd"> <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 $dir = '../uploads'; $files = scandir($dir); foreach ($files as $image) { if (substr($image, 0 , 1) != '.') { $image_size = getimagesize ("$dir/$image"); $image_name = urlencode($image); echo "<li><a href=\"javascript:create_window('$image_name',$image_size[0],$image_size[1])\">$image</a></li>\n"; } } ?> </ul> </body> </html> function.js // Script 11.3 - function.js function create_window (image, width, height) { width = width + 10; height = height + 10; if (window.popup && !window.popup.closed) { window.popup.resizeTo(width, height); } var specs = "location=no, scrollbars=no, menubars=no, toolbars=no, resizeable=yes, left=0, top=0, width=" + width + ", height=" + height; var url = "show_image.php?image=" + image; popup = window.open(url, "ImageWindow", specs); popup.focus(); }
