How to show a random image from a album

http://modxcms.com/forums/index.php/topic,29764.0.html

Create this snippet and edit it. Set path and image sizes. Call it uncached. [[!RandomImage]]
Works like a charm.

Hi,

I also wanted to display a random image with GalleryItem snippet (from any album).
So I changed few lines in GalleryItem snippet as I didn’t want to wait until the next update

.....

/* get ID of item */
if($id !=’random’) { $id = (int)$modx->getOption(’id’,$scriptProperties,false); }
if ($modx->getOption(’checkForRequestVar’,$scriptProperties,true)) {
$getParam = $modx->getOption(’getParam’,$scriptProperties,’galItem’);
if (!empty($_REQUEST[$getParam])) { $id = (int)$_REQUEST[$getParam]; }
}
if (empty($id)) return ’’;

/* setup default properties */
$tpl = $modx->getOption(’tpl’,$scriptProperties,’galItem’);
$toPlaceholders = $modx->getOption(’toPlaceholders’,$scriptProperties,true);
$toPlaceholdersPrefix = $modx->getOption(’toPlaceholdersPrefix’,$scriptProperties,’galitem’);
$albumTpl = $modx->getOption(’albumTpl’,$scriptProperties,’galItemAlbum’);
$albumSeparator = $modx->getOption(’albumSeparator’,$scriptProperties,’, ’);
$albumRequestVar = $modx->getOption(’albumRequestVar’,$scriptProperties,’galAlbum’);
$tagTpl = $modx->getOption(’tagTpl’,$scriptProperties,’galItemTag’);
$tagSeparator = $modx->getOption(’tagSeparator’,$scriptProperties,’, ’);
$tagSortDir = $modx->getOption(’tagSortDir’,$scriptProperties,’DESC’);
$tagRequestVar = $modx->getOption(’tagRequestVar’,$scriptProperties,’galTag’);
/* get item */
$c = $modx->newQuery(’galItem’);
$c->select($modx->getSelectColumns(’galItem’,’galItem’));
if($id != ’random’) {
$c->where(array(’id’ => $id)); }
else {
$c->sortby(’RAND()’,’ASC’);
$c->limit(1); }

$item = $modx->getObject(’galItem’,$c);
if (empty($item)) return ’’;

....



And it works with :
[[!GalleryItem? &id=`random` ]]

(tested with Revo 2.1.1 with Gallery 1.2.1)

Hi!
I’ ve tested mediaandco code with MODX Revolution 2.1.1-pl and gallery 1.2.1 too, and it didn’t work for me. It’s look like on word ’random’ snippet making something wrong ?

feature request filed:
https://github.com/splittingred/Gallery/issues/142

For anyone that just wants to grab a random thumbnail, I created a chunk called "myRandomThumb" with the below code:

and called from my template:

Simple and easily expanded upon. Hope this helps whoever else comes along.

hello,
is there some working solution to display random image from any album?

On my previous post I had stated that I had it working. Now, not so much. I am in the process of moving several websites to a new server and decided to upgrade revo to a newer version while I was at it. It took some time to even realize that it stopped rotating the image.

Old setup:
Revo 2.1.3
Gallery 1.4.0

New setup:
Revo 2.2.5
Gallery 1.5.2

I don't know what changed...

come on guys give some solution on this problem, please!

If this helps, my code posted a year ago does work, it will grab a random image. I believe the issue I am having is a caching issue. If I clear the website cache, the code will grab a completely different image on the next page load. I have still not found what is causing revo2.2.5 to hold onto the generated image instead of grabbing a different one on every page load.

do you have this snippet-call directly on your template, or do you have it in another chunk?

Not sure, if it can be an issue, if you have your snippet wrapped in a cached chunk.
I think, I had lastly an issue like that.
