Code:

<?php

function Get_Image_list($dir) {
if(!$dir) {
  $dir = ".";
}
$file_array = array();
$dir_handle = opendir($dir);
$a = 0;
while($file = readdir($dir_handle)) {
if((preg_match('/jpg/',$file)) || 
   (preg_match('/png/',$file)) || 
   (preg_match('/gif/',$file)) ||
   (preg_match('/jpeg/',$file)))  {

   $file_array[$a] = $file;
   $a++;
}
}

return $file_array;
}

$files = Get_Image_list($dir);

$max = count($files)-1;
srand((double)microtime()*1000000);
$index = rand(0,$max);
$image_name = $files[$index];

?>
<img border=0 alt="random image" src="<? echo "$dir/$image_name";?>">

I pulled this from evil walrus so I could study it for my random webpage stuff...then I got impatient and just decided to try to use it for my random avatar...no it will display on my page but, not on the board...

That is because this script isn't designed correctly to work. It would take a rewrite to work properly in an avatar field. To be specific, you can't put a img tag inside an image tag or a url. For instance that script is printing out <img src="url">, but message boards put the url inside of the image tag... so in other words what that script is creating is an image tag inside of an image tag like this:

Code:

which is the problem with this script, but even putting just the url will not work, you have to open and dump the contents of the image file.

Here is my script:

Code:

<? 
$absolute_path = "/home/yoursite/public_html/avatars"; 
$dir = opendir($absolute_path); 
while($avatar = readdir($dir)) { 
if (($avatar != "..") and ($avatar != ".")) { 
   $avatars[] = "$avatar"; 
} 
} 
$avatars = str_replace(chr(32),"%20",$avatars); 
$random = array_rand ($avatars, 1); 
$randomAvatarURL=$avatars[$random]; 
$avatar = fopen("$absolute_path/$randomAvatarURL", "r"); 
while (!feof ($avatar)) { 
        print fread($avatar,120); 
} 
fclose($avatar); 
?>

It took me a while, but, I got it working...eperfect kept on going down on me...Anyway, thanks for the script Chris...It's a lot easier to understand than the one I got from evil walrus. Now, using the same idea I am going to try to make a random script to grab HTML pages in the same way that does....it should be interesting.

Alright for those who are using my avatar script, I have something to say, the avatar directory must not contain anything BUT avatar images, the avatar script itself is not supposed to be in the directory either. My script doesn't check to see if the file is an image or if it is not... so your avatars will display x's if there is a file in your avatar directory that is not an image(including my script).

I noticed both juncmodule and Kon-Tiki's show x's which means that you have something in the avatar directory that isn't an image file.

That's odd...I see the x's but, I don't have anything extra in that directory...all of the images I do have in the directory display properly. I will have to wait and log on at home and see if I can find out what is causing that...

I think eperfect got mad at me...I crashed the server with that script (had the directory wrong). Opps ;D

edit: actually, if you go here http://www.juncmodule.com/avatar you can see the files in the directory...

Make sure that all 3 of them are uploaded in binary mode. Other than that... not sure why it would be messing up.

Also I built a new avatar script last night... much better than my first because this one allows me to choose which extensions are allowed, plus an option to choose your avatar that you want displayed in the url. If you would be interested in the new script just ask.

When you say choose extension...do you mean that I could use it for .HTML too? Either way, I would be interested in at least checking it out. I'm not sure when I'm going to have time to create my own scripts. I haven't even finished my scratchpad yet...all I have to do is throw in a few functions and it's done...blah, maybe this weekend.

By the way, how long have you been programming with PHP?

I will upload all of my images again in binary when I get home just to make sure.

Thanks for all the help Chris!

later,

By extension I mean it doesn't check the file type, it will load anything and everything that is in the avatar directory even if it isn't a image file.

Hey Chris, when you go to www.juncmodule.com/avatar.php and refresh enough times at one point it displays the text "Options All". That is why my avatar displays a blank from time to time. Do you know what could be causing that?

Hmmmm, well you could try looking for and censoring that text in the script.

ARGH!!! There WAS a file in there...It was hidden, couldn't see it through the URL or FTP, but, I could see it through the cpanel! It appears to be fixed...so yay!
