Randomize your background every refresh!
 
1 Attachment(s)
this is a simple .php file, and small "Style Vars" edit to make it so your background changes on your forum every time you refresh the page, using the popular extensions, such as .jpg, and .png.


rotate.php

PHP Code:
<?PHP 
$dir = 'images/blood/backgrounds/'; //change this to the directory where your background images are from the root directory!
$images = array(); 
$extensions = array('png', 'jpg', 'gif'); 
 
if (!file_exists($dir)) 
 die('directory not found'); 
 
$fp = @opendir($dir); 
 
while ($file = @readdir($fp)) 
{ 
 $info = pathinfo($file); 
 if (in_array($info['extension'], $extensions)) 
  $images[] = $file; 
} 
 
@closedir($fp); 
 
$bg = mt_rand(0, count($images) - 1); 
header('Location: ' . $dir . $images[$bg]); 
?>
put this file into your root directory.

Make sure to change the directory to the background images you want!


Changing the Style Var via doc_background
  1. Go to your admincp, click "Style Manager"
  2. select your favorite skin on the drop down menu select "Style Vars"
  3. in the Style Vars menu, search for "doc_background"
  4. Once there replace the Background Image field with url(location of your rotate.php) ex: url(phpfiles/rotate.php) then hit save.

And your finished!

I did not create this, but tested it, and had the idea for it, had permission to share this.

LGKeiz 05-09-2010 11:47 PM
No. you don't touch vbulletin.css; you can do it from the Style Vars Editor...

I cannot get this to work and I have no idea why. I can get any of my 50ish backgrounds to show on their own but once I add the script how I should it just shows no background. Anyone willing to check it out for me and see if I am doing something wrong? I am using the warrior theme.

paramegsoft 05-15-2010 12:40 PM
wow that is cool

but i think it make some load in the server

SamDelgado 05-16-2010 09:55 PM
Still looking for an answer to this...

SamDelgado 05-17-2010 10:41 AM
I am getting this error with the script when I go directly to the script url

Warning: Cannot modify header information - headers already sent by (output started at /home/content/05/5148505/html/toplolclips/images/warrior/backgrounds/rotate.php:1) in /home/content/05/5148505/html/toplolclips/images/warrior/backgrounds/rotate.php on line 21

What am I doing wrong?

NNJJ 05-17-2010 07:59 PM

This file was created from scratch... compare sources before posting idiotic posts like this, Thank you.


And for those who are still having issues, I will get my developer to answer your questions asap.

EDIT: tbh I forgot I released this.

Make sure rotate.php is in your ROOT directory, not your images directory.

Try placing rotate.php in your root vBulletin folder if it isn't already there.

Please provide the following information:
  • Location of rotate.php (full URL if possible)
  • Location of background images you wish to use (full URL if possible)
  • The second line of rotate.php. ($dir = ...)
  • The Background Image field of doc_background in Style Vars.

Also, the script has been slightly modified. I uploaded and pasted the wrong code but it shouldn't have caused any errors either way.

I attempted to use this, thought it would be a fun update for the website, however I only get a black background when I try.

Location of rotate.php: Root directory
- www.distortedguild.com/rotate.php

Location of background images: /images/backgrounds/
- http://www.distortedguild.com/images.../Cataclysm.jpg

Second line of rotate.php: $dir = 'images/backgrounds/';
(attempted using $dir = '/images/backgrounds/'; also, but still was not successful.

The background image field of doc_background in Style Vars: url(rotate.php)


Hope that info helps.

LGKeiz 06-01-2010 11:17 AM
rotate.php is detecting that the directory isn't found.

try another directory..

"directory not found"

I will get my developer to help you out as soon as I can.

davidmoon 06-24-2010 02:15 AM
This is working awesome for me ... though I'm only rotating 5 backgrounds. :)

Bouncer222 06-25-2010 01:24 AM
I installed this, but it's not working for me. Can anyone help me? You can only see it while the page is changing. But once its finished loading, its the same background on it, the one that's set by the style.

My guess is the style is custom coded differently or something? IDK.
Would appreciate any help. I set the stylevar image url to: url(images/backgrounds)

JasonReynolds 06-25-2010 02:23 PM
Great mod thanks :D

Did you already have a pre-set background with CSS built on with your layout? If so you got to clear the CSS off that...

does this work for vb 4.1.3?

thank u

HagbardCeline 04-14-2011 07:13 PM
I've seen this php code to get randomized images from a folder. The idea is really good, but we can do it better. I don't like the solution, to send headers with the randomized image, but first step, a little code cleanUp.

Works with php 5.3+

PHP Code:
<?php

$images = array();

try {
    foreach (new FilesystemIterator(dirname('images/YOURFOLDER/*')) as $file) {
        
        if (!preg_match('#^(.*)\.(gif|png|jpg)$#i', $file)) {
            continue;
        }
        
        $images[] = $file->getPathname();
    }
}
catch (Exception $e) {
    // do something like -> header('Location: images/background/alternativeImage.jpg'); 
}

$image = mt_rand(0, count($images) - 1); 
header('Location: ' . $images[$image]);
Don't use

PHP Code:
?> 
to close the php code! We don't need it...

Cheers

Lemonwater 04-22-2011 06:40 PM
screenshot please...

socialteenz 07-20-2011 06:32 PM
Any one got this working?

temsamane 10-10-2011 05:16 PM
is this working on vb 4.1.5

hivitro 11-02-2011 10:37 AM
@HagbardCeline: Nice clean up. Thank

@Lemonwater: Why you need an Screenshot? simple. you can change the background or any css variable and random it.

@temsamane: its an external php code, to ramdom images, if the php server run, it will run..

@ALL: If you put too many big pictures to the background, your server will have a serveral load tranfering images.

Ex. If you have: 10 diferents images, of 100kb. 200 users, read 5 diferent post, you will tranfer: 200x5x100= +-100 mb only to show a diferent background?

temsamane 12-06-2011 08:05 PM
is there any update/same mod for this one?
