Situation:

You have a folder with just one article. If someone goes into this folder, you want to show the article directly. If there are more articles than one, you want to show the user a list of these articles.

To apply below solutions you will have to put the code into an override template for the folder class full view. I.e. this means you create a template which consists of the code from below, put it into /design/yourdesign/override/templates and in your override.ini.append point to this new template for class id 2 (folder). See what exactly to put in the override.ini.append.

Solution 1:

Use this code:

{* Get the articles (ClassID: "2"! Might be different for you!) *}

{let articles=fetch('content','list',hash(parent_node_id,$node.node_id,class_filter_type,"include",class_filter_array,array(2)))}

 

{* Get a count of the articles (ClassID: "2"! Might be different for you!) in this folder. *}

{let articles_count=fetch('content','list_count',hash(parent_node_id,$node.node_id,class_filter_type,"include",class_filter_array,array(2)))}

 

{* Now decide what to do *}

{switch name=decision match=$articles_count}

{case match=1}

       {* Show this if there is only one article! E.g. include the "full article view" page. *}

       {section name=Article loop=$articles}

               {node_view_gui view=full content_node=$decision:Article:item}

       {/section}

{/case}

{case}

       {* Show this for more than one article. *}

       {section name=Article loop=$articles}

               <h3>{$decision:Article:item.name}</h3>

               {$decision:Article:item.data_map.intro.data_text}<br /><br />

               {section name=read_link show=$decision:Article:item.contentobject_version_object.data_map.body}

                       <a href={concat("/content/view/full/",$decision:Article:item.node_id)|ezurl}>Read more...</a>

               {/section}

               <hr />

       {/section}

{/case}

{/switch}

Solution 2:

Another solution that may be better in terms of speed, depending upon your site design. The difference here is the use of the keyword 'limit' which will limit the number of articles to be returned. For example, the code given below will only return a single article and display it. (Difference to solution 1: this solution will always show just 1 article. Solution 1 will show all articles if there are more than 1.)

{let articles=fetch(content,

                   list,

                   hash(parent_node_id, $node.node_id,

                        limit, 1,

                        class_filter_type, "include",

                        class_filter_array, array(2)))

}

 

{section name=Article loop=$articles}

       {node_view_gui view=full content_node=$Article:item}

{/section}

 

{/let}

Solution 3 for 3.4:

You need two steps:
For 3.4 and the new demo folder full view use:
design/news/override/templates/full/folder.tpl

{* Folder - Full view *}

<div class="content-view-full">

   <div class="class-folder">

 

       {section show=is_unset( $versionview_mode )} {*start 1*}

       {section show=$node.object.data_map.show_children.content}

           {let page_limit=10

                list_items=array()

                list_count=0}

 

           {section show=or( $view_parameters.day, $view_parameters.month, $view_parameters.year )}

               {let time_filter=array( and,

                                       array( 'published', '>=',

                                              maketime( 0, 0, 0,

                                                        $view_parameters.month, cond( $view_parameters.day, $view_parameters.day, 1 ), $view_parameters.year ) ),

                                       array( 'published', '<=',

                                              maketime( 23, 59, 59,

                                                        cond( $view_parameters.day, $view_parameters.month, $view_parameters.month|inc ), cond( $view_parameters.day, $view_parameters.day, 0 ), $view_parameters.year ) ) )}

               {set list_items=fetch_alias( folder_children, hash( parent_node_id, $node.node_id,

                                                            offset, $view_parameters.offset,

                                                            attribute_filter, $time_filter,

                                                            sort_by, $node.sort_array,

                                                            limit, $page_limit

                                                           ) )

                    list_count=fetch_alias( folder_children_count, hash( parent_node_id, $node.node_id ) )}

               {/let}

           {section-else}

               {set list_items=fetch_alias( folder_children, hash( parent_node_id, $node.node_id,

                                                            offset, $view_parameters.offset,

                                                            sort_by, $node.sort_array,

                                                            limit, $page_limit  ))}

               {set list_count=fetch_alias( folder_children_count, hash( parent_node_id, $node.node_id ) )}

           {/section}

             <div class="content-view-children">

             {switch match=$list_count}

                            {* If only one article in folder: display this in full article view *}

                            {case match=1}

 

                            {/case}

                            {* If more than one article in folder: display list of articles in line view *}

                            {case}

                              <h1>{$node.object.data_map.name.content|wash()}</h1>

       {/section}

 

                            {/case}

                            {/switch}

                   {section var=child loop=$list_items sequence=array(bglight,bgdark)}

                            {switch match=$list_count}

                            {* If only one article in folder: display this in full article view *}

                            {case match=1}

                               {node_view_gui view=full content_node=$child}

                            {/case}

                            {* If more than one article in folder: display list of articles in line view *}

                            {case}

 

                            {node_view_gui view=line content_node=$child}

                            {/case}

                            {/switch}

                  {/section}

           {include name=navigator

                    uri='design:navigator/google.tpl'

                    page_uri=$node.url_alias

           </div>

       {/section}

          {/section}{*end 1 *}

 

   </div>

</div>

and because auf the fetch_alias you need to add these lines to your
settings/siteaccess/news/fetchalias.ini.append.php

[folder_children]

Constant[sort_by]=priority;0

Parameter[parent_node_id]=parent_node_id

Parameter[offset]=offset
