[SOLVED] How to check if current page has any children

[Sphinx]

Hi

I can't figure out how I determine if the current page has any childrens.
I am trying to make a conditional that shows a submenu only if there are childrens.

conceptually something like this in my page template:

Code: Select all

{if $haschildren == true}
<ul><li>{menu template='simple_navigation' start_level='2' collapse='1'}</li></ul>
{else}
some other content here
{/if}

but I can't figure out where I get a variable like the fictive $haschildren from.

I can't simply handle this in the menu template as this is not called at all in cases where there are not children..

Any help appreciated!

Check this post... It might help...

IIRC is there some logic in CGExtensions as well, to get some add.info on pages...

Thanks..

Ok, it seems I can't avoid switching to inline PHP in my template code then. Here's a short test and it works:

Code: Select all

{php}

global $gCms;
$manager =& $gCms->GetHierarchyManager();
$thisPage = $gCms->variables['page_name'];
$currentNode = &$manager->sureGetNodeByAlias($thisPage);

$nodes = $currentNode->getChildren();

if ($currentNode->hasChildren()) {echo "SUBMENU";}else{echo "NO SUBMENU";}

{/php}

I had hoped for a solution via already assigned variables, but this is fine. Thanks!

You could check CGExtensions.... IIRC is it having such variables....

After several trials of my own, I stumbled upon your code. Thank you for this solution.

Since I don't think an inline php is good either, I took your code and made it into a User Defined Tag called get_page_haschildren

Code: Select all

global $gCms;
$manager =& $gCms->GetHierarchyManager();
$thisPage = $gCms->variables['page_name'];
$currentNode = &$manager->sureGetNodeByAlias($thisPage);

$nodes = $currentNode->getChildren();
$ph = 0;
if ($currentNode->hasChildren()) {$ph = 1;}

$var = 'page_haschildren';
$smarty->assign($var,$ph);

I used a trick I learned previously -> how to assign a value to a smarty variable inside a UDT.

In my template I use the following code:

Code: Select all

{get_page_haschildren}
{if $page_haschildren}
  <div id="page-menu">{menu start_page=$page_alias number_of_levels="2" template="pagemenu"}</div>
{/if}

The call to get_page_haschildren can be done anywhere as long as it is done before the use of the $page_haschildren smarty variable.

The call to the menu module is just what I want to display if the page has children but one can do anything else instead.

Thanks again.
