{random_cat_image} how can I have another one
« on: December 24, 2008, 12:31:26 PM »
ok here what i want: I need to have 2 random images in the details page.  A good workaround to this is to include another {random_cat_image}

But

when i have {random_cat_image}{random_cat_image}, it shows the same image.

Now

I thought of having {random_cat_image2} which calls random_cat_image2.html

where can I do this?

Since random images is the smallest bottleneck of the script (aka it has most impact on the site's performance), 4images caches random images for each category that improves performance if more then one random image needed, that's why it doesn't matter how many times you tried get a random image for the same category (on same page) it will be the same. Other words, any changes to this will degrease your site performance.

In details.php (and/or in categories.php) find:
$random_cat_image = (defined("SHOW_RANDOM_IMAGE") && SHOW_RANDOM_IMAGE == 0) ? "" get_random_image($cat_id);

Insert below:if (!defined("SHOW_RANDOM_IMAGE") || SHOW_RANDOM_IMAGE != 0)
{
  
$random_image_cache get_random_image_cache();
  
$random_cat_image2 get_random_image($cat_id);
  
$site_template->register_vars("random_cat_image2"$random_cat_image2);
}


Use {random_cat_image2} tag

I did it this way

$random_cat_image = (defined("SHOW_RANDOM_IMAGE") && SHOW_RANDOM_IMAGE == 0) ? "" : get_random_image($cat_id);
$random_cat_image2 = (defined("SHOW_RANDOM_IMAGE") && SHOW_RANDOM_IMAGE == 0) ? "" : get_random_image($cat_id);
$site_template->register_vars("random_cat_image2", $random_cat_image2);
$site_template->register_vars("random_cat_image", $random_cat_image);
unset($random_cat_image);
unset($random_cat_image2);


it works now but both show the same pic  :oops:

What to do now? or is there any other way to use 2 random pics inside details page with less performance impact?

Sorry, my mistake, I've updated my post above. Should work now.
