Hello!

I'm using PHP and Smarty to try to build an array of arrays using the
results from nested queries. I am just learning about nested arrays,
and I'm not sure what I'm doing wrong.

I am hoping someone can give me a hint as to what I am doing wrong.

If I remove the PHP foreach loop, it works fine, except, of course, no
sub projects show up. :) The error must be in there, but I'm just not
seeing it.

I get the following error with the code below:

Warning: Smarty error: unable to read resource: "welcome/Object.tpl" in
/usr/local/lib/php/Smarty/Smarty.class.php on line 1088

PHP STUFF
$query ="SELECT * FROM projects WHERE parent_project_id is NULL OR
parent_project_id = ''";

$projects = $db->getAssoc($query, DB_FETCHMODE_ASSOC);

foreach ($projects as $key => $project) {
$query ="SELECT * FROM projects WHERE parent_project_id =
$projects[$key]['project_id']";
$sub = $db->getAssoc($query, DB_FETCHMODE_ASSOC);
$projects[$key]['subs'] = $sub;
}
$tpl->assign('projects', $projects);

SMARTY STUFF
{foreach from=$projects item='entry'}
<b>{$entry.short_name}</b><br />
<ul>
{foreach from=$entry.subs item='sub'}
<li>{$sub.short_name}</li>
{foreachelse}
<li>No subs for this project</li>
{/foreach}
</ul>
{foreachelse}
<b>No projects found</b>
{/foreach}

Can anyone point me in the right direction?

Thanks,
Amanda
