Hi all, long time no post but I'm back and expect to here more from me over the next few weeks... I've been searching ez forums for the answer to a question I'm sure I asked in the past but I can't find it anywhere, I'm sure when I ask it it'll hit me like a wet brick in the face, but here goes. How can I count the child nodes of a parent to find the last node? Situation: this is the same problem I have faced a number of times but I'm not sure how I overcame it in the past.
I have a (you guessed it) list... e.g.
<ul>
<li>item</li>
...
</ul> I need to apply a class="last" attribute to the (you guessed it again... are you all psychic?) last list item. Can someone please refresh my memory how to do this? I know how to fetch using the list_count etc. I'm just lost at the bit where I do the if else thing... I knew you'd understand, what a great bunch of people you are ;) Cheers!
Pardon me while I burst into flames...

I should just elaborate on that a little... If I was to use a fetch like:
{def $count=fetch('content', 'list_count', hash('parent_node_id', $m_menu.node_id) )
$sub_menu=fetch( 'content', 'list', hash( 'parent_node_id', $m_menu.node_id,
'sort_by', array( array( 'priority' ) ),
'class_filter_type', include,
'class_filter_array', array('folder') ) ) }
Where $m_menu.node_id is the id of the parent which I have already fetched. How can I take $count and find the last child? I know there must be a simple way to do this but as I have been away from the ez template code for a few months I'm finding it quite hard to get back into the groove! Any ideas are most welcome. Cheers!

Hy, You can perhaps try :
{fetch( 'content', 'list',
hash( 'parent_node_id', X,
'offset', 1,
'limit', 1 )} Patrice

Hi Patrice, Thanks for the input,I'm not sure that will find the last child node? But then again I'm a little rusty so I'll poke around the docs a bit to see if offsets and limits will help! Cheers! PS: All other input still welcome!

Ok I've made some progress here but I'm one step off the solution and I can't figure it out. For my navigation I'm running a request to find my top level nodes, and foreach of these top nodes I'm running a sub request for any children they may contain. Additionaly I'm counting the children with list_count. My $count returns the number of children (at the moment this is 9).
I'm using:
{foreach $sub_menu as $index => $s_menu} $index naturally returns 0 - 8. My problem is that although 8 is the last child, the total number of children is 9 and I can't use offset on list_count, so I can't do something like {if $count|eq($index)}do something{/if} Which is the sort of thing I need to be able to do, does anyone have any Ideas at all how I might do this? Is there any way to reduce the count by 1, this would work because the total count will always be returned 1 bigger than the index? Any help really welcome. Cheers!

I got it, ignore my last post... The answer for anyone interested:
<ul id="main-menu">
{def $home=fetch('content', 'node', hash('node_id', $topnode_id) )
$main_menu=fetch('content', 'list', hash('parent_node_id', 2,
'sort_by', array( array( 'priority' ) ),
'class_filter_type', include,
'class_filter_array', array('folder') ) ) }
{def $m_count=$main_menu|count|dec()}
{foreach $main_menu as $m_index => $m_menu}
<li{if $m_index|eq($m_count)} id="last"{/if}><a{if eq($module_result.path[1].node_id,$m_menu.node_id)} class="current"{/if} href={$m_menu.url_alias|ezurl}><span><span>{$m_menu.name}</span></span></a>
{def $sub_menu=fetch( 'content', 'list', hash( 'parent_node_id', $m_menu.node_id,
'sort_by', array( array( 'priority' ) ),
'class_filter_type', include,
'class_filter_array', array('folder') ) ) }
{def $s_count=$sub_menu|count|dec()}
{if $sub_menu|count|gt(0)}
<ul class="sub-menu">
{foreach $sub_menu as $s_index => $s_menu}
<li{if $s_index|eq($s_count)} class="last"{/if}><a href={$s_menu.url_alias|ezurl}>{$s_menu.name}</a></li>
{/foreach}
</ul>
{/if}
</li>
{/foreach}
{undef}
</ul>
I was able to use the dec operator to deincrement the total count by one, now the count equals the last value of the indexed loop. Hope this helps others. Cheers!
