Change sentinel value inside a switch - possible scope issue

James Ward	Tuesday 30 September 2003 2:20:59 pm Hi all. I would like to create a section that does something different on the first iteration than for all subsequent iterations. I am attempting to fetch related objects for my example. I placed the following code in an article with 3 related objects: {let runcheck=0} {section show=count($node.object.related_contentobject_array)\|gt(0)} {section name=Rel loop=$node.object.related_contentobject_array} {switch name=FirstRun match=$runcheck} {case match=0} First Run runcheck = {$runcheck}<br /> {set $runcheck=1} {/case} {case} Sebsequent Run runcheck = {$runcheck}<br /> {/case} {/switch} {/section} {/section} {/let} This returns: First Run runcheck = 0 First Run runcheck = 0 First Run runcheck = 0 Hardly the desired result. I tried using $#runcheck=1 but it made no difference. I read the documentation on let and set and namespaces. Is it even possible for me to change the value of $runcheck inside my switch or do I need to come at this another way? Thanks in advance. working at www.wardnet.com blogging at www.jamesward.ca
James Ward	Friday 03 October 2003 10:14:57 am O.K. I'm a little closer to a solution. Instead of using a sentinel value inside the switch I check the index of the section to see which itteration I'm on. The problem now is how to close my table. Currently the </table> appears regardless of the <table> tag. This can create some dandy layout problems. Is there a way to check if I am on the last itteration of a section, or a way to set a sentinel variable inside a section so I can tell if its code was run? Here is the code I am currently using. If someone else has a better way of listing related objects I'd love to hear it. {Related Objects List} {section name=total show=count($node.object.related_contentobject_array)\|gt(0)} {section name=Rel loop=$node.object.related_contentobject_array} {section-exclude match=$:item.contentclass_id\|eq(5)} {switch match=$:index} {case match=0} <table width="150" border=0 cellpadding=3 cellspacing=0 class="related-information-table"> <tr> <td class="related-information-title">Related Information</td> </tr> <tr> <td><ul> <li><a class="related-information-link" href={concat("/content/view/full/",$:item.main_node.node_id)\|ezurl}>{$:item.name}</a></li> {/case} {case} <li><a class="related-information-link" href={concat("/content/view/full/",$:item.main_node.node_id)\|ezurl}>{$:item.name}</a></li> {/case} {/switch} {/section} </ul></td> </tr> </table> {/section} {End Related Objects List} working at www.wardnet.com blogging at www.jamesward.ca

Hi all.
I would like to create a section that does something different on the first iteration than for all subsequent iterations.

I am attempting to fetch related objects for my example. I placed the following code in an article with 3 related objects:

{let runcheck=0}
{section show=count($node.object.related_contentobject_array)|gt(0)}
{section name=Rel loop=$node.object.related_contentobject_array}
{switch name=FirstRun match=$runcheck}
{case match=0}
First Run runcheck = {$runcheck}<br />
{set $runcheck=1}
{/case}
{case}
Sebsequent Run runcheck = {$runcheck}<br />
{/case}
{/switch}
{/section}
{/section}
{/let}

This returns:
First Run runcheck = 0
First Run runcheck = 0
First Run runcheck = 0

Hardly the desired result. I tried using $#runcheck=1 but it made no difference. I read the documentation on let and set and namespaces. Is it even possible for me to change the value of $runcheck inside my switch or do I need to come at this another way?

Thanks in advance.

O.K. I'm a little closer to a solution.
Instead of using a sentinel value inside the switch I check the index of the section to see which itteration I'm on. The problem now is how to close my table. Currently the </table> appears regardless of the <table> tag. This can create some dandy layout problems.
Is there a way to check if I am on the last itteration of a section, or a way to set a sentinel variable inside a section so I can tell if its code was run?

Here is the code I am currently using. If someone else has a better way of listing related objects I'd love to hear it.

{*Related Objects List*}
{section name=total show=count($node.object.related_contentobject_array)|gt(0)}
{section name=Rel loop=$node.object.related_contentobject_array}
{section-exclude match=$:item.contentclass_id|eq(5)}
{switch match=$:index}
{case match=0}
<table width="150" border=0 cellpadding=3 cellspacing=0 class="related-information-table">

<td class="related-information-title">Related Information</td>
