Navigate through related images

Robert Malevic	Tuesday 18 November 2008 3:58:32 am Hi All, I need a template which should display related images one at the time. I use this code to fetch related images and to display the first image: {foreach $node.data_map.images.content.relation_list as $relatedImage} {def $obj=fetch('content', 'object', hash('object_id', $relatedImage.contentobject_id))} {attribute_view_gui attribute=$obj.data_map.image image_class='original'} {undef $obj} {break} {/foreach} My problem is that in the loop above I need a break else all related images will be shown. What I want to do is fetch all related images, show the first image and add navigation to navigate through the other images. I tried to access the related images separately but somehow I am only able to display all related images. Any suggestions how to navigate through each related image separately? Thanks!

I would have done this like this : {def $count=$node.data_map.images.content.relation_list\|count() $offset=0 $object='' } {if $view_parameters.offset} {set $offset=$view_parameters.offset} {/if} {def $obj=fetch('content', 'object',hash('object_id', $node.data_map.images.content.relation_list[$offset].contentobject_id))} {attribute_view_gui attribute=$obj.data_map.image image_class='original'} {undef $obj} {if $offset\|gt(0)} <a href="{$node.ul_alias\|ezurl('no')}/(offset)/{$offset\|dec()}">Previous</a> {/if} {if $offset\|lt($count)} <a href="{$node.url_alias\|ezurl('no)}/(offset)/{$offset\|inc()}">Next</a> {/if} Cheers Maxime Thomas maxime.thomas@wascou.org \| www.wascou.org \| http://twitter.com/wascou Company Blog : http://www.wascou.org/eng/Company/Blog Technical Blog : http://share.ez.no/blogs/maxime-thomas

Hi All,

I need a template which should display related images one at the time.
I use this code to fetch related images and to display the first image:

{foreach $node.data_map.images.content.relation_list as $relatedImage}
    {def $obj=fetch('content', 'object',
                        hash('object_id', $relatedImage.contentobject_id))}
                        {attribute_view_gui attribute=$obj.data_map.image image_class='original'}         
    {undef $obj}
    {break}
{/foreach}

My problem is that in the loop above I need a break else all related images will be shown. What I want to do is fetch all related images, show the first image and add navigation to navigate through the other images.
I tried to access the related images separately but somehow I am only able to display all related images.

Any suggestions how to navigate through each related image separately?

Thanks!

Hi,

I'm not sure your code is the best way to reach your aim.
I would have done this like this :

{def $count=$node.data_map.images.content.relation_list|count()
      $offset=0
      $object=''
}

{if $view_parameters.offset}
{set $offset=$view_parameters.offset}
{/if}

{def $obj=fetch('content', 'object',hash('object_id', $node.data_map.images.content.relation_list[$offset].contentobject_id))}
{attribute_view_gui attribute=$obj.data_map.image image_class='original'} 
{undef $obj}
{if $offset|gt(0)}
<a href="{$node.ul_alias|ezurl('no')}/(offset)/{$offset|dec()}">Previous</a>
{/if}

{if $offset|lt($count)}
<a href="{$node.url_alias|ezurl('no)}/(offset)/{$offset|inc()}">Next</a>
{/if}

Cheers
