Indeed...I think that's sort of the same thing I said, only clearer. I was
writing a response to Doc's original post earlier and I think I thought that
some of the wording I used in that message was included in the one I ended
up sending, which might have been a bit confusing.
:)
Ah, here, found it. This is the more generic version of what I did...
Doc's using DBI to get his data, so I'll put up the DBI-specific part of my
code as well...Even though he's using fetchrow_hashref with a while loop and
I'm using selectall_arrayref, we end up with the same data structure.
# Get the data...
$arrayref = $dbh->selectall_arrayref( $query, { Columns => {} } );
# arrayref now contains a reference to an array of hashrefs...ie, a loop.
# or, if no data was returned, arrayref is undefined.
$arrayref = [ {} ] if !$arrayref;
# This sets up arrayref as an EMPTY loop, which wont display any data, but
# will keep H:T from throwing an error.
Hope this helps.

Subject: RE: [htmltmpl] Error code.
| Hey Brian,
|
| I believe the error is prompted by ref( $data->{'rows'} ) not being
"ARRAY",
| most likely rows is undef() or something along those lines. I could
totally
| be wrong though, this is just my experience.
|
| To fix it, I usually use something along the lines of
|
| $data->{'rows'} = get_my_rows() || [] ;
|
| Although, I would never actually name the variable 'rows'.
