I'm trying to use the shuffle-operator found here :

http://www.ez.no/community/contributions/template_plugins/random_sort_array_or_fetch_shuffle_operator

The extension is installed, my directory is called extensions, is put on the EZ root, and configured in site.ini.append.php. I can't get it to work though...

{let randomised_array=fetch('content','tree', hash('parent_node_id', '77'))|shuffle}
{section name=random loop=$randomised_array}
{$:item.name}  -- testing</br>
{/section}
{/let}

This is in my pagelayout, the fetch works, but it comes with the same list on every reload. I'm clearing the caches, so I don't think that's the problem. Any suggestions? Is there a place where I can check whether the extension is properly installed=

Well, in 3.3 at least you can check to ensure an extension is enabled by going to yoru Admin area, choosing the <i>Setup</i> tab, clicking on <i>Advanced</i> and then choosing <i>Extension Setup</i>. The box next to the shuffle operator needs to be checked.

Yeah, your template code looks fine, so I'd guess it's something to do with the way the extension is installed. I have shuffle working and looked at my override/site.ini.append.php, it has two entries for shuffle:

[ExtensionSettings]
ActiveExtensions[]=shuffle

and

[TemplateSettings]
ExtensionAutoloadPath[]=shuffle

Try including both if you haven't already.

James

Thanks guys, but still no success.

The shuffle operator is activated within the admin interface.
I have the correct lines in my site.ini.append.php.

James, could you please compare your extension folder to mine?

site/extensions/shuffle/ ->contains readme.txt and shuffleoperator.php
site/extensions/shuffle/autoloads/ ->contains eztemplateautloload.php

Might the problem be that my extension directory is named extensions instead of extension?
I have altered that in the site.ini.append.php, so that would be strange...

The directory name may very well be the problem as <i>eztemplateautoload.php</i> contains the path extension/shuffle/shuffleoperator.php

Bjørn, I hope your file in:
site/extensions/shuffle/autoloads/ is called eztemplateautoload.php and not eztemplateautloload.php as you have written.

Got it!

That loload was just a typo :)

Thx Alex, it was just extensions instead of extension directory which caused the problem.
Now I'll get around to some shuffling!

Well, so far so good, I've got a random list...

{let randomised_array=fetch('content','tree', hash('parent_node_id', '77',
						class_filter_type, "include", class_filter_array, array(17)))|shuffle}

{section name=random loop=$randomised_array}

{node_view_gui view=element content_node=$random:item} </br>

{/section}
{/let}

This shows every object fetched in a random order, and works just fine, but I only want to show ONE result. Any ideas on how to do that? It would be pointless to set a limit on the fetch, because then I wan't have anything to shuffle... It should be an easy thing to achieve I guess, but I can't seem to figure it out at the moment...

Maybe this will work ;)

{let randomised_array=fetch('content','tree', hash('parent_node_id', '77',
						class_filter_type, "include", class_filter_array, array(17)))|shuffle}

{section name=random loop=$randomised_array max=1}

{node_view_gui view=element content_node=$random:item} </br>

{/section}
{/let}

Thanks a million.

I knew it had to be simple. Even though I've broken my leg, I didn't think it would affect my brain in such an ugly manner. Must be side-effects from medication during surgery :)

Nice bit of code Zinistry. I've somehow missed the <i>max</i> attribute of <i>{section}</i> causing me to solve the issue (pulling a single random object) in a different way. Instead of looping through the objects a single time, I pull the first item in the generated array. It is good to see a different way to achieve the same goal. I may well change my templates after playing with <i>max</i>. :) The code I've written looks like:

{let KID=fetch(content,tree,hash(parent_node_id,186,class_filter_type,include,class_filter_array, array(14)))|shuffle}
  <a href={$KID.0.url_alias|ezurl}>{attribute_view_gui attribute=$KID.0.data_map.image image_class=ce_main}</a><br />
  <a href={$KID.0.url_alias|ezurl}>{$KID.0.data_map.type_model.content|wash}
{/let}

Thanks!
