randomizing images

it seems that my code will randomize if i run the the script through the browser but it doesnt randomize if i put it in an image page

HTML Code:

<img src="$vboptions[bburl]/banners.php" />

and

the code is:

PHP Code:


		
			
<?php 

$img= array();

$img[] = "banner1.gif"; 

$img[] = "banner2.gif"; 

$img[] = "banner3.gif";

$img[] = "banner4.gif";

$img[] = "banner5.gif";

$img[] = "banner6.gif";

$img[] = "banner7.gif";

$img[] = "banner8.gif";

$img[] = "banner9.gif";

$dir = "http://dev.animationation.net/images/banners/";

$rand = rand(0, count($img) - 1); 

$img = $img["$rand"]; 

header("Location: $dir$img");

?>

Why not do this :

in your code :

PHP Code:


		
			
<?php

$img= array();

$img[] = "banner1.gif";

$img[] = "banner2.gif";

$img[] = "banner3.gif";

$img[] = "banner4.gif";

$img[] = "banner5.gif";

$img[] = "banner6.gif";

$img[] = "banner7.gif";

$img[] = "banner8.gif";

$img[] = "banner9.gif";

$dir = "http://dev.animationation.net/images/banners/";

$rand = rand(0, count($img) - 1);

$img = $img["$rand"];

$path = "<img src=\"".$dir.$img."\">";

?>

The above is the banner.php file.

Then use an include in your main page you want to show the banner in :

PHP Code:


		
			
include('./banner.php');

and place :

PHP Code:


		
			
echo $path;

whereever u want it to show.

That's the wrong way to do it. You need to read the file data, set some header information and then echo it out. Look at attachment.php for an example.

if you had

HTML Code:

<img src="$vboptions[bburl]/banners.php" />

then why would you need

HTML Code:

$dir = "http://dev.animationation.net/images/banners/";

in the random script ? I mean the url for the images' location.

and if you use it in vb3 why don't we use a template ?

and (yes, and T_T) why not mt_rand ?

it outputs the image but it doesnt change the image unless i visit the script directly.

my current code is:

PHP Code:


		
			
<?php 

$img= array();

$img[] = "banner1.gif"; 

$img[] = "banner2.gif"; 

$img[] = "banner3.gif";

$img[] = "banner4.gif";

$img[] = "banner5.gif";

$img[] = "banner6.gif";

$img[] = "banner7.gif";

$img[] = "banner8.gif";

$img[] = "banner9.gif";

$img[] = "banner10.gif";

$dir = "http://dev.animationation.net/images/banners/";

$rand = mt_rand(0, count($img));

$randimg = $dir;

$randimg .= $img["$rand"]; 

header('Content-type: image/gif');

header('Location: '.$randimg.'');

?>
