[TEMPLATE SYNTAX] vb:each from piece of an array

[rossco_2005]

I have an array:

PHP Code:

$binaries = array(
    0 => array(
        'subject'    => 'Subject 1',
        'binaryid'    => 1,
        'groups'    => array('alt.binaries.teevee', 'alt.binaries.multimedia')
    ),
    1 => array(
        'subject'    => 'Subject 2',
        'binaryid'    => 2,
        'groups'    => array('alt.binaries.xvid')
    ),
); 


I then render a template:

PHP Code:

$templater = vB_Template::create('ng_managebinaries');
    $templater->register_page_templates();
    $templater->register('navbar', $navbar);
    $templater->register('binaries', $binaries);
print_output($templater->render()); 


In my template I can use this code fine:

<vb:each from="binaries" value="binary">
	{vb:raw binary.subject}
	{vb:raw binary.binaryid}
</vb:each>

But this template code would give me an error:

<vb:each from="binaries" value="binary">
	{vb:raw binary.subject}
	{vb:raw binary.binaryid}
	<vb:each from="binary.groups" value="group">
		{vb:raw group}
	</vb:each>
</vb:each>

The error that I get is:

Warning: Invalid argument supplied for foreach() in D:\Sites\vbdev\includes\class_core.php(3917) : eval()'d code on line 142

Does anybody know what would be the correct syntax to use for this (from="binary.groups" is probably incorrect)? Or have I found a vBulletin bug?

I figured this out.
I must use this:

<vb:each from="binaries" value="binary">
	{vb:raw binary.subject}
	{vb:raw binary.binaryid}
	<vb:each from="binary['groups']" value="group">
		{vb:raw group}
	</vb:each>
</vb:each>

(from="binary['groups']" instead of from="binary.groups")
Just incase anyone is wondering, or searching for the same answer.

Thanks to whoever looked.

That info also comes in handy if you're trying to use any arrays inside of a curly bracket.
For example:

{vb:rawphrase {vb:raw item['phrase']}}
