Script 10.4 Images.php

Paul_Blackpool · April 7, 2015

I am having a problem when I click on the link that this script creates. My structure is D://xampp/uploads (This is where the images have been uploaded to) My main files are in D://xampp/htdocs/tuition.

When I publish the script in the browser it sees the images in the table I.E.:

Image Name - Image Size

basketball.jpg 154kb

penguins.jpg 89kb

I have checked and double checked the code. I have also tried replacing line 46 from $dir = '../../uploads'; // Define the directory to view. to $dir = 'D://xampp/uploads'; // Define the directory to view. But i still get the same error:

The page code is:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>
	<meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
	<title>Images</title>
	<script language="JavaScript">
	<!-- // Hide from old browsers.
	
	// Make a pop-up window function:
	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 pop-up window:
		popup = window.open(url, "ImageWindow", specs);
		popup.focus();
		
	} // End of function.
	//--></script>
</head>
<body>
<p>Click on an image to view it in a separate window.</p>
<table align="center" cellspacing="5" cellpadding="5" border="1">
	<tr>
		<td align="center"><b>Image Name</b></td>
		<td align="center"><b>Image Size</b></td>
	</tr>
<?php # Script 10.4 - 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");
		
		// Calculate the image's size in kilobytes:
		$file_size = round ( (filesize ("$dir/$image")) / 1024) . "kb";
		
		// Make the image's name URL-safe:
		$image = urlencode($image);
		
		// Print the information:
		echo "\t<tr>
\t\t<td><a href=\"javascript:create_window('$image',$image_size[0],$image_size[1])\">$image</a></td>
\t\t<td>$file_size</td>
\t</tr>\n";
	
	} // End of the IF.
    
} // End of the foreach loop.
?>
</table>
</body>
</html>

However when I click in the link to show the image in a popup window I get the error:

Object not found!
