Randomly rotate logo

Posted: Sat Apr 12, 2003 1:03 pm

I have 5 images that I want to randomly rotate as the logo and they are all the same size. The code as to go in the theme.php file. Does anybody know how to do this?

Code:

<?php

//Edit this line to the url of your image folder to randomize
//Must be a relative URL in your server, do not put in a forward
//or trailing slash for it to work.
$url='images/logos';
//Stop editing, that is all. Call the image with <img src=url/filename.php> That's all, enjoy. :D

$files=array();
if ($handle=opendir("$url")) {
while(false !== ($file = readdir($handle))) {
   if ($file != "." && $file != "..") {
   if(substr($file,-3)=='gif' || substr($file,-3)=='jpg' || substr($file,-3)=='png' || substr($file,-3)=='bmp') $files[count($files)] = $file;
   }
}
}
closedir($handle);

$random=rand(0,count($files)-1);
if(substr($files[$random],-3)=='gif') header("Content-type: image/gif");
elseif(substr($files[$random],-3)=='jpg') header("Content-type: image/jpeg");
elseif(substr($files[$random],-3)=='png') header("Content-type: image/png");
elseif(substr($files[$random],-3)=='bmp') header("Content-type: image/bmp");
readfile("$url/$files[$random]");

?>

I can't figure out exactly where to put this code and how to make it work.

Put your file in the includes directory then use the code as you posted. Replace the logo.gif with filename.php see if that works.
//Stop editing, that is all. Call the image with <img src=url/filename.php> That's all, enjoy. Very Happy

That didn't work, does anybody have any original code or code that they made work?

I want to be able to call a random image function from anywhere on the site, I would need to send the function the absolute URL of the images so it can choose the images from that directory.

ex: I call the function with the parameter of an absolute URL

the function then randomly chooses an image from that directory and sends back the file name and extension

Anybody know how to make an include file that will do this?

P.S. can this be called from inside an echo command?
