 Posted: Mon Jan 21, 2008 2:05 pm Post subject: Randomizing script |
 |
|
I'm looking for a randomizing script that'll allow me to display an image on a page, and when the page is refreshed display a new random image.
I'm having trouble finding a user friendly script, I'm not the world's greatest at coding, so something a code newb like me could use with little trouble (or even something not so easy if it came with detailed instructions) would be a big help.
Thanks! |

You leave open too much questions.
Random image as if, you enter the url and it displays a random image from a directory. Or a random image on a page?

I would say he is looking for something that displays on a page with other content (such as a random header rotator, like imusion.net has)
Do you want the script to load the images from a directory, or a list that you specify in the script? And have you checked hotscripts.com? They would likely have the most user friendly scripts.

| Yeah, sorry, I mean random images from a directory. And I totally forgot to check hotscripts, I used to have a bookmark for the site but I didn't think to check there. Thanks! |

I've got a random image script (slightly modified to not always change) in my signature, actually.
| Code: | // array of image URLs
$imgs = array('...');
// random image
$value = array_rand($imgs);
// send it out
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Location: $imgs[$value]"); |

| Ok, thanks, that may be just what I need. Um, I feel silly asking, but could you explain how to implement it? |

I'll see if I can get it right. I've added additional comments:
| Code: |
// array of image URLs
$imgs = array('...');
/* In the line above, you want to list all of your images where the '...' is. This works fine if you have a small number of images. I think it should be in the format: array(0 => "path/to/img1.jpg" "path/to/img2.jpg" "path/to/img3.jpg" "path/to/img4.jpg"); *\
// random image
$value = array_rand($imgs);
// send it out
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Location: $imgs[$value]"); |
Another option if you want the entire directory:
| Code: | if ($handle = opendir('.')) { // Here replace the '.' with '/path/to/directory/'
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$arrayimages = $arrayimages . $file . ",";
}
}
closedir($handle);
}
// array of image URLs
$imgs = array($arrayimages);
//This does the same as above, except it lists the URLS automatically based on the dir you specified.
// random image
$value = array_rand($imgs);
// send it out
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Location: $imgs[$value]");
|
Its been a while since I last coded PHP, so somebody would have to check up on what I wrote for accuracy (or you can test it and let me know what happens and I might be able to fix it).
