I'm no expert, but I believe it's because you didn't pack the hash with
an array. For instance;
$tmplvar->{hashkey} = "aa" is wrong
$tmplvar->[0]->{hashkey} = "aa" is right
So for a hash of hashes your string would be
$tmplvar->[0]->{hashkey}->[0]->{hashkey} = "aa"

Subject: [htmltmpl] html template loops (hash of a hash)
I'm a bit new to html templates, so I apologize in advance if I ask some
obvious questions.
I'm working on an HTML::Template loop issue that I can't quite seem to
get
working just right. Instead of an array of hashes, I'm using a hash of
hashes.
When I try and run it, it gives me this error:
-----------------------
Not an ARRAY reference at ./index2.cgi line 85.
-----------------------
Don't think this is a Perl error, so I'm thinking it's an HTML::Template
error, maybe.
Here's an example of the data set I'm using:
The Perl I'm using to pack the hash of hash into something I thing HTML
template will understand is below.
If anyone can think of what would cause this, let me know. I think I
may be
trying to push the limits of HTML::Template farther than it supposed to.

=====================================================
80 my @loop; # the loop data will be put in here
81
82 # fill in the loop, sorted by fruit name
83 foreach my $vendor (sort keys %vendor_hoh) {
84 # get the files from the data hash
85 my ($rif, $rif_out, $graph, $raw, $percent1, $percent2,
$percent3)
= @{$vendor_hoh{$vendor}};

names

89 my %row = (
90 rif => $rif,
91 rif_out => $rif_out,
92 graph => $graph,
93 raw => $raw,
94 percent1 => $percent1,

Template(s)
======================================
I have two templates. The first is called index.tmpl.template. It's a
template for the real template. I couldn't figure out how to replace
the top
layer of hashes, so I'm using the perl script to auto-create the real
index.tmpl from index.tmpl.template based on the first layer. Perl that
does
this is here:
=======================================
if ( /TMPL_LOOP_PLACE_HOLDER/ ) {
foreach $rif_file (sort @files) {
my @rif_fields = split(/\./,$rif_file);
$APP = (@rif_fields)[0];
$MONTH = (@rif_fields)[1];
$vendor_hoh{$APP}->{'rif'} = "${APP}.${MONTH}.rif";
$vendor_hoh{$APP}->{'rif_out'} = "${APP}.${MONTH}.rif.out";
$vendor_hoh{$APP}->{'graph'} = "${APP}.${MONTH}.graph_toc.htm";
$vendor_hoh{$APP}->{'raw'} = "${APP}.${MONTH}.raw.gz";
$vendor_hoh{$APP}->{'percent1'} =
"${APP}.${MONTH}.country_percentages.txt";
$vendor_hoh{$APP}->{'percent2'} =
"${APP}Software_Usage${MONTH}.txt";
$vendor_hoh{$APP}->{'percent3'} =
"${APP}Software_percent_Usage${MONTH}.txt";
print OF "\n<TMPL_LOOP NAME=\"$APP\">\n";
print OF "<TMPL_IF NAME=\"rif\"><TMPL_VAR rif></TMPL_IF>\n";
print OF "<TMPL_IF NAME=\"raw\"><TMPL_VAR raw></TMPL_IF>\n";
print OF "</TMPL_LOOP>\n\n";
}
}
=======================================
Example of what the template "template" looks like:
=-=-=-=-=-=-=-=-=-=-=-=
<TMPL_LOOP NAME="TMPL_LOOP">
<!- TMPL_LOOP_PLACE_HOLDER ->
</TMPL_LOOP>
=-=-=-=-=-=-=-=-=-=-=-=
When my index.cgi script runs, it reads this index.tmpl.template and
replaces
<!- TMPL_LOOP_PLACE_HOLDER -> with the real data of:
<TMPL_LOOP NAME="$APP">
<TMPL_IF NAME="rif"><TMPL_VAR rif></TMPL_IF>
<TMPL_IF NAME="raw"><TMPL_VAR raw></TMPL_IF>
</TMPL_LOOP>
Where $APP is the main key of my hash of hash.
Example of the finished index.tmpl is below:
=-=-=-=-=-=-=-=-=-=-=-=
<TMPL_LOOP NAME="TMPL_LOOP">
<TMPL_LOOP NAME="application_1">
<TMPL_IF NAME="rif"><TMPL_VAR rif></TMPL_IF>
<TMPL_IF NAME="raw"><TMPL_VAR raw></TMPL_IF>
</TMPL_LOOP>
<TMPL_LOOP NAME="application_2">
<TMPL_IF NAME="rif"><TMPL_VAR rif></TMPL_IF>
<TMPL_IF NAME="raw"><TMPL_VAR raw></TMPL_IF>
</TMPL_LOOP>
<TMPL_LOOP NAME="application_3">
<TMPL_IF NAME="rif"><TMPL_VAR rif></TMPL_IF>
<TMPL_IF NAME="raw"><TMPL_VAR raw></TMPL_IF>
</TMPL_LOOP>
<TMPL_LOOP NAME="application_4">
<TMPL_IF NAME="rif"><TMPL_VAR rif></TMPL_IF>
<TMPL_IF NAME="raw"><TMPL_VAR raw></TMPL_IF>
</TMPL_LOOP>
<!- TMPL_LOOP_PLACE_HOLDER ->
</TMPL_LOOP>
