Great! That worked! At least, it didn't get any errors. :)
Now, I am trying to loop through both arrays on the HTML/Smarty side,
but nothing is showing up. The name of the project does not show up,
but for each iteration of the loop, it prints out "- id ()" and "No subs
for this project", even for projects that have sub projects. I've never
used a Smarty "foreach" before - I normally use Smarty "sections", and
I'm not getting any errors, so I'm not sure what I'm doing wrong.
{foreach from=$projects item='entry'}
<b>{$entry.short_name}</b> - id ({$entry.project_id})<br />
<ul>
{foreach from=$entry.subs item='sub'}
<li>{$sub.short_name} - {$sub.project_id}</li>
{foreachelse}
<li>No subs for this project</li>
{/foreach}
</ul>
{foreachelse}
<b>No projects found</b>
{/foreach}
