Hi!

There are many ways of sorting nodes in eZ Publish. I have the following question I have not found an anwer to:

I have a folder with nodes of the same class contain data. I can use the following code to sort them:

{fetch( 'content', 'list', hash( 'parent_node_id', 42,

                                 'sort_by',        array( 'attribute', 

                                                          false(), 

                                                          'data_name' ) ) )}

My first question is: in whcih file should I put this code? In the folder.tpl-file?

My second questions is: is it possible to make the above code into a hyperlink so that users can choose how to sort by clicking on a link on my page?

Thank you,
Jens

Hello!

I'm still a newbie in ez but I think that it will works like that

To classify the nodes you can put variables into the url and get them thanks to the $view_parameters function.

// template code

{def $var=false()}
{def $sorting='DESC'}

{if $view_parameters.sorting|eq('DESC')}
{set $var=true()}
{set $sorting='ASC'}
{else}
{set $var=false()}
{set $sorting='DESC'}
{/if}

{fetch( 'content', 'list', hash( 'parent_node_id', 42,
                                    'sort_by',
				     array( 'attribute', $var, 'data_name' )
			             ) )} 

// Link
<a href={concat($node.url_alias,"/(sorting)/",$sorting)|ezurl}>DESC</a>
