simple variable problem

Wednesday 21 April 2004 3:31:47 am

I have a variable problem that is bugging me

I have a general .tpl that I use only for my homepage. It loops through alle related objects of the homepage (articles) and displays an introduction and link to each article. This is working fine.

However. The articles can have an object relation (defined with in the article class), which point to an image. If so, it should be displayed. I cannot properly instantiate this image object! please help, this should be easy. I keep getting a namespace error.

I want to fetch the object, assign is to a variable and use the variable to access the object and it's attributes

{section name=Related loop=$current_node.object.related_contentobject_array}
{* loop through all related objects *}
{* first get the parent to define placement on the page*}
{set-block name=homepageContent scope=global variable=parentID}
{$Related:item.parent_nodes.0}
{/set-block}
{switch match=$homepageContent:parentID}
{case match=49} {* categorie 1 *}
{set-block name=homepageContent scope=global variable=content}
{$Related:item.data_map.introductie.content}
{/set-block}
{set-block name=homepageContent scope=global variable=contentlink}
<a href={$Related:item.main_node.url_alias|ezurl} title=" ">more...</a>
{/set-block}
{* ************ *}
{* and now I need to fetch the image and put it in an object variable*}


{let name=homePageContent object=fetch( 'content', 'object', hash( 'object_id', $Related:item.data_map.thumbnail.content.id ))}
{/let}
{/case}
{/switch}

..can't figure it out

Hi alex, thanx for the reply

I will try your code suggestion and change the variable scope to root.
however, the part about the parentid per se is not causing the problem ( i think)
homePageContent.parentid used in the case if functional (although the code might not be ideal. Using the homePageContent namespace makes it simple to access the variables in the rest of the pages code.
the real problem lies in the part

{* ************ *}
{* and now I need to fetch the image and put it in an object variable*}

{let name=homePageContent object=fetch( 'content', 'object', hash( 'object_id', $Related:item.data_map.thumbnail.content.id ))}

the let defined here is not working. If I use the fetch in a set-block, like I do with the other two attributes, it actually returns something like "(ezContentobject) ... "
Can't remember exact, but it looks like it does fetch the object i want. The problem is that a set-block only returns strings, preventing me from actually using the attributes within the object. So I need a working alternative for

set-block name=homepageContent scope=global variable=myobject>
{fetch( 'content', 'object', hash( 'object_id', $Related:item.data_map.thumbnail.content.id ))}
{/set-block}

because this returns the string and I want to place the object in a variable, in my homepageContent namespace.

a let to init (all) the variable(s) and a set to fetch the real content.

{let name=data var=false}
{set var=fetch(...)}
{$data:var}
{/let}

hi guys,

this solved my problem indeed. i knew it was supposed to be easy! I also implemented some code to check whether an image has been added. If so, fetch it! First I added the 'let' to my section

{section name=Related loop=$current_node.object.related_contentobject_array}
{let myobject=false}

then I added the following logic

{* get the object relation. *}
{* from the related object, extract the image and the alternative text and create an image tag (if exists*}
  {* check if homepage picture is available, if so proces it *}
  {section show=ne($Related:item.data_map.thumbnail.content.id,'')}
  {set myobject=fetch( 'content', 'object', hash( 'object_id', $Related:item.data_map.thumbnail.content.id ))}
  {set-block name=homepageContent scope=global variable=mythumbnail}
  {* check if the object has been set, if so: create the image tag*}
  {section show=ne($Related:myobject,'')}
	<img src="{$Related:myobject.main_node.data_map.image.content.small.url}" alt="{$Related:myobject.main_node.data_map.caption.content.output.output_text}">
  {section-else}
  {/section}
  {/set-block}
  {section-else}
{/section}

then I added
<i>{$homepageContent:mythumbnail}</i> where I want to show the thumbnail.

I guess the conditional part needs some improvement. suggestions are welcome!

thanx again for the help!
