[Resolved] Banner Image Rotater

mrphish0812

I am a php newbie, confused about how to start this script ...

what do I replace 'pwd' with? Tried the images folder and everything else??? Thanks for Your Help!

$dir = exec('pwd');

$open_dir = opendir("$dir");

$image_ext_array = array(

    "jpg",  
    "gif",          
    "JPG", 
    "GIF",

);

$image_files = array();

if(!$open_dir){
die("can not open!$dir");
}
else{

$show_img = array_rand($image_files);

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header ("Cache-Control: no-cache, no-store, must-revalidate, private, max-age=0, proxy-revalidate, no-transform");
header ("Pragma: no-cache");
header ("Vary: User-Agents");

$image_alt = "New at Michael Gordon Innovations!";

$image_location = $dir . "/" . $image_files[$show_img];

$image_width = getimagesize($image_location);
$image_height = getimagesize($image_location);

echo "<img src=\"$image_files[$show_img]\" width=\"$image_width[0]\" height=\"$image_height[1]\" alt=\"$image_alt\">";

header ("location: http://mglcorp.com/site/whatsnew/$image_files[$show_img]");

}

exec is a shell execution command, which is executing a command called pwd in this instance...

I am not sure what that command is. I don't think it is a Windoze application, and I don't know what it would be if it were a *nix command.

Instead, maybe, just do something like:

$dir = "path/containing/files";

Hi Robb, TheDefender's answered your main question but I'd done this already (had a bad connection last night ... might as well have it anyway).

Here's a template for displaying a random image from a given directory.

Notice that you can give absolute paths like ...

http://www.etc.com
http://www.etc.com/images

... or relative paths like ...

.
..
./images

<html>
<head>
<title>Images</title>
</head>
<body>
<?php
/* 	Can be relative or absolute path */
$dir = '.';

if(!$dh = opendir($dir)){
	// Shut the program down
	die('Cannot open '.$dir); 
}

// Just list in lowercase ... see below
$image_ext_array = array("jpg", "gif", "png"); 
$image_files = array(); 
while (false !== ($file = readdir($dh))){
    // readdir only returns the filename, not the full path name
	$full_path = $dir.'/'.$file;

// check it is a file (not a folder, etc)
if(is_file($full_path)){
	// Want to extract the extension
	$path_info = pathinfo($full_path);
	$extension = strtolower($path_info["extension"]);
	// Check the extension (make lowercase to simplify)
	if(in_array($extension, $image_ext_array)){
		$image_files[] = $full_path;
	}
}
}
closedir($dh);

// Get a random index
$rand_image_index = array_rand($image_files); 
$image_alt = "New at Michael Gordon Innovations!"; 

// Get the full path
$image_full_path = $image_files[$rand_image_index]; 

// Get the size array
$image_size = getimagesize($image_full_path); 
$image_width = $image_size[0];
$image_height = $image_size[1];

$image_html = '<img src="'.$image_full_path.'" width="'.$image_width.'" height="'.$image_height.'" alt="'.$image_alt.'">'; 
echo 'Random image HTML: <pre>'.htmlspecialchars($image_html).'</pre><hr>';
echo 'Random image:<br>'.$image_html.'<hr>';
?> 
</body> 
</html>
