Hmm, I havn't seen or used any rand() function.
But I think http://www.ez.no/community/contribs/template_plugins/random_sort_array_or_fetch_shuffle_operator
could work. But I haven't used it.
There is a nice thread about it to here: http://ez.no/community/forum/setup_design/struggling_with_shuffle_operator

There are no confirmation that the extension is activated.

But you can see if it has been started. It should be checked at the "Extension"-page.

oh i see... so it means it already started??
hmm.. think is my code again.. bcos, my banner dont come out, it is not being display

can check for mi whether my codes are correct

{let randomised_array=fetch('content','list', hash('parent_node_id', '76',
class_filter_type, "include", class_filter_array, array(2)))|shuffle}

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

{node_view_gui view=element content_node=$random:item}

{/section}
{/let}

thanks a lot

Try and check randomised_array to see if you get some (and expected) output.

I would use: {$randomised_array|attribute(show)}

is it like this??

{let randomised_array=fetch('content','tree', hash('parent_node_id', '76',
class_filter_type, "include", class_filter_array, array(2)))|shuffle}

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

{$randomised_array|attribute(show)}

{/section}
{/let}

it doesn't display anything..
just want to ask, the arrary(2), means what?? the 'tree' refers to what??

thankz :)

I meant like this:

{let randomised_array=fetch('content','tree', hash('parent_node_id', '76',
class_filter_type, "include", class_filter_array, array(2)))|shuffle}

{$randomised_array|attribute(show)}

{/let}

Seems like you need to check out the docs for fetch function ;-) Here are some explanation in my own words:

The 'array(2)' is combined with the class_filter_array that stands infront of it. (ie class_filter_array=array(2)). In all it means that the fetch will just include content that has the class id = 2 . You need to check what class the object you want to loop has.

The 'tree' is the type of fetch you want to do. The tree-type-fetch grabs all content below parent_node_id including content in sub-folders.

Check out the docs for fetch and you will find more alot more info (and probably better explained ;-) )

oh okie.. think im still nt clear with the syntax..

i try the above codes, and i only got the following output

Attribute Type Value

what does it show?? no items being call??

thanks..

oki, try without the shuffle function first:

{let randomised_array=fetch('content','tree', hash('parent_node_id', '76',
class_filter_type, "include", class_filter_array, array(2)))}

{$randomised_array|attribute(show)}

{/let}

And make sure that the parent_node and that the class of the objects you want to get is correct. If you use the above code the parent node should be 76 and class = 2

If those are correct you should get all objects printed.

Can you get it working?

erm.. found the id.. it is wrking.. my class id is wrong..
thanks alot :)

how can i display the image??

Tobias Persson

The parent_node should be: 'Node ID' of the folder where you have your objects. (in ezpublish 3.4 you find the number in top of the preview of every object.) (in 3.5 you find it in 'Details' of every object)

The class ID (or ID)can you find in Configuration/Classes (thats for ez 3.4).
In 3.5 you find the ID in Setup/Classes.

Edit: Saw that you got it working while I wrote this. Great :-) Now can you add the shuffle function.

I need to loop the object for six times and show its name at the same time
meaning that:

{section name=Loop Loop=5}

-- anything in here is repeated 6 times successfully--

{/section}

The problem is that i need to display the name of some specific children for 6 times [looping over a variable]

{section name=Child loop=fetch('content','list', hash('parent_node_id', 58))} }

{$:item.name}

{/section}

So how could i merge both cases in the Loop parameter

Hope you can help me

Thanks in advance

Hi,

You can use "max" attribute

{section name=Child loop=fetch('content','list', 
                           hash('parent_node_id', 58))} max=6}

{$:item.name}

{/section}

Hi,

Thanks a lot for answering, but using the max attribute needs at least 6 objects to be entered through the content while i need to fix 6 cells [to keep the design look ] even if there's only one object entered and that's what the { loop=6} does , So unfortunately this is not what i want

Please do infrom me with any solution u may reach

Thanks in advance

Hi,

Fetching 6 nodes, so it loops 6 times or i don`t understand what you want to do ...

fetch('content','list', hash('parent_node_id', 58, limit, 6))
