Dear Smarty Smarties,

This is a bit long. But, it's long because it's tough (I think so, anyway).

I am having a problem finding a combination of {foreach} and {section}
that will do what I want it to do. This may be due to the fact that I
have never fully grasped {section}, unfortunately. Anyway...

I have an array of projects. Each value in this array is an
associative array containing data regarding that project. The final
key is 'dirs', whose value is an array of associated filesystem
directories for the project's files. In this array, the directories
are the keys and the values are an array of files. Each file is an
associative array of the file's information (filename, date created,
description, etc.). The array I'm working with is below.

I have the ability to alter the array structure if needed. The array
is as it is because using this structure got me the closest to what I
wanted. Part of the problem is that the keys of one of the arrays (the
directories) are actually data I want. I'm not sure how to fix that.

Here's the array:

Array (4)
0 => Array (6)
project_id => 4
companyname => Signal US Communications
projectname => Project 4
description => blah blah
datecreated => Jun 27th
dirs => Array (0)
1 => Array (6)
project_id => 2
companyname => Matt's Huge Company
projectname => Project 2
description => blah blah
datecreated => Jun 27th
dirs => Array (0)
2 => Array (6)
project_id => 3
companyname => Google, Inc.
projectname => Project 3
description => blah blah
datecreated => Jun 27th
dirs => Array (0)
3 => Array (6)
project_id => 1
companyname => Matt's Huge Company
projectname => Project 1
description => blah blah
datecreated => Jun 27th
dirs => Array (2)
test => Array (2)
0 => Array (4)
file_id => 99
filename => foo.txt
description => blah blah blah
datecreated => 1119914453
1 => Array (4)
file_id => 99
filename => bar.txt
description => blah blah blah
datecreated => 1119914453
test2 => Array (0)

Here's the code I am using (very abbreviated):

{foreach from=$projects item=project name=project}
{$project.projectname}
{foreach from=$project.dirs|@array_keys item=dir name=dir}
{$dir}
{foreach item=dirfiles from=$project.dirs}
{foreach from=$dirfiles item=file name=file}
{$file.filename}
{/foreach}
{foreachelse}
dffasdfasdfasdfasdfasdf
{/foreach}
{foreachelse}
This project has no directories.
{/foreach}
{foreachelse}
There are no projects in the database.
{/foreach}

And here is the output. You'll notice that it works except that if you
click on 'View Directories' on Project 1, and then click on the two
'View Files' links, the two files (foo.txt and bar.txt) show up in
both the 'test' and 'test2' directories, whereas in the array they
exist only in the 'test' directory. I think that's happening is that
the dirs array is being looped through and all files are bring printed
twice, but i'm not sure.

Can anyone help me? I'm kind of stuck here, and I don't want to have
to compromise separation of presentation just to get around me not
being able to wield Smarty appropriately. Again, feel free to offer
simpler constructions of the array. I just need to output what is
shown.

Thanks a million, in advance.
