iv been lookin for some time for a scrpt that will display an image from any dir under a image/ dir and i just wanted to know if anyone knows how to get a random file form any dir under a certin dir.
maybe some one could sugest a random image script too.
<?php
$dir = 'images';
function scan_directory($dir)
{
global $list;
$dirlist = opendir($dir);
while (false !== ($file = readdir($dirlist)))
{
if ($file != '.' && $file != '..')
{
$newpath = $dir.'/'.$file;
if (is_dir($newpath)){
scan_directory($newpath);
} else {
array_push($list,$newpath);
}
}
}
closedir($dirlist);
}
$list = array();
scan_directory($dir);
$key = array_rand($list);
header("Location: http://" . $_SERVER['HTTP_HOST'] . "/{$list[$key]}");
exit;
?>Put that in a file pic.php outside the images directory, and you can use it in an img tag <img src="pic.php"> from any page.
Thanx alot nibbler
Thanks for the code, how's the CPG integration going?
im havein proglems with the script, i put it in the img tag and it wont load any image, i look at the image props and its lookin for the image pic.php
its finding the file in the dir but the redirect isnt goin to the right folder... its goin down to the root dir and than /images/...
oh i got it, i changed the header location, the img tag is workin now, thanx
