Shortest random image method

Seen lots of debate over random image methods, here's one for the pot

If your on x-cart 3.3.8 or over use

Code:

[img]yoursitepath/image{[/img]

hows this work? Notice the

image{"1"|mt_rand:5}.gif

Generating a random number between 1 and 5 using smarty so in the html it's

image5.gif or image3.gif etc etc

Simply name your images image1.gif, image2.gif, image3.gif etc and set the mtrand:X to the amount you have in the folder.

If your running on an older x-cart then the smarty that is installed doesnt support the random function.

...And if are running an older version of X-cart less than version 3.3.8:

Save the following code to Smarty-2.1.1/plugins/function.random.php.

:!: Note your Smarty-2.1.1 directory may differ.

Code:

<?

        /*

         * Smarty plugin

         * -------------------------------------------------------------

         * File:     function.random.php

         * Type:     function

         * Name:     random

         * Author:   Ben Godfrey <ben@hypothetical.co.uk>

         * Purpose:  outputs a random number in the range specified 

by min and max attribs or 0 and mt_randmax

         * Usage:    {random min=0 max=10}, {random min=-10}, 

{random max=20} or just {random}

         * -------------------------------------------------------------

         */



        function smarty_function_random($params, &$smarty) {

                extract($params);



                if (empty($min)) $min = 0;

                if (empty($max)) $max = mt_getrandmax();



                // complain about erroneous args

                if (!is_numeric($min)) {

                        $smarty->trigger_error("random: parameter 'min' must be a number");

                        return;

                }

                if (!is_numeric($max)) {

                        $smarty->trigger_error("random: parameter 'max' must be a number");

                        return;

                }



                print(mt_rand(floor($min), ceil($max)));

        }



        // initialise random number sequence

        mt_srand(time());

?>

How to use it in .tpls?

Code:

{random min=0 max=10}, {random min=-10}, {random max=20} or just {random}

Kudos!

Quiet a old post but the random image method given by
groovico still works great for me. Because I want to have
different images than the product or detailed images
random loaded.

But I also would like it to load several images at the same time
and on the same page, and in a way there are no duplicate
images loaded. Would that be possibe?

Furthermore, is there a way to make the random loaded
images clickable, so that clicking on them will open the
corresponding product page?

I hope that somebody can help or knows another way to
load clickable images other than the product or detailed images.
Thanks in advance!

Wow, this is so easy to do its amazing. I was researching how to add a bunch of javascript to do this for the last couple hours until I found this post.

Excellent, fantastic, amazing, easy.

thank you thank you thank you

Remember the literal statement.

You don't need it for my example above, it's not javascript, it's done in smarty.

Sorry, is for the link that I post, it use Java
