I have an invalid foreach on my multidimentional array...please help! :)

[Jade Elizabeth]

I'm trying to work with my multidimentional array to create a menu but I am stumped on how to make this work. I would really appreciate some pointers because everything I've looked at online is either stupid and doesn't apply or doesn't work when I try it.

All I want in the end is category link printed, then the type links printed, and then when I work that out I will print the subtypes links.


WorkIndex.php

// Retrieve the categories and boards.
require_once($sourcedir . '/Subs-WorkIndex.php');
$workIndexOptions = array(
'base_level' => 0,
'parent_id' => 0,
'include_categories' => true,
'countChildStats' => true,
);
$context['work_categories'] = getCategoriesTypes($workIndexOptions);
}

WorkIndex.template.php - Problem HERE

Code Select Expand

function template_main()
{
global $context, $txt, $scripturl;

echo '<pre>';
//print_r($context['work_categories']);
echo '</pre>';
works_menu();

}

function works_menu()
{
foreach ($context['work_categories'] as $id_cat => $category)
{
print_r($category['link']);

foreach ($category['types'] as $id_type => $type)
{
print_r($type['link']);
}
}

}

$context['work_categories'] prints this:

$context is not in scope in works_menu.

Crap so I forgot to global it. Far out so much to remember XD.

I will give that a go later when I load it back up. Thank you!!
