[htmltmpl] TMPL_LOOP limit or count

[David A. Bandel]

Folks,

Been using HTML::Template in a few projects. Really nice not to have
HTML tangled in the Perl code.

Got a largish hash I am sorting. Want to output only about 15 lines
of the table. Is there a way to tell the loop to stop?

Here's what I'm doing:

my @calloutdata;
foreach $callskey ( sort {$callnum{$b} <=> $callnum{$a}} keys %callnum){
my %outbound;
$outbound{EXTENNUMCALLED} = $callskey;
$outbound{TIMESCALLED} = $callnum{$callskey};
push( @calloutdata, \%outbound );
}

$template->param( OUTBOUNDS => \@calloutdata );

The calloutdata array winds up to be about 200 lines long. Any way to
have the TMPL_LOOP stop output after 15 or so table lines?

Nothing in the docs suggests a way to do this (or am I missing something?).

TIA,

David A. Bandel

}

Well, the first thing I'd do is suggest that if possible you just don't
put all 200 things into the loop. That would save on your processing if
you didn't have to create the big loop to begin with.

But if you needed them in the loop in some places but didn't want to
display them in others, you can use the __counter__ loop context var
combined with HTML::Template::Expr.

<tmpl_loop outbounds>
<tmpl_if expr="__counter__ <= 15">
...
</tmpl_if>
</tmpl_loop>

Nothing in the docs suggests a way to do this (or am I missing something?).

It's not possible with just HTML::Template, but HTML::Template::Expr
should help you get there.

Unfortunately, in order to do what I'm doing (you haven't seen the
code that comes before), I need all the values all at once or the sort
on the value of the key/value pair doesn't work.

But if you needed them in the loop in some places but didn't want to display
them in others, you can use the __counter__ loop context var combined with
HTML::Template::Expr.

It's an idea. But hoping to keep it simple.

<tmpl_loop outbounds>
 <tmpl_if expr="__counter__ <= 15">
   ...
 </tmpl_if>
</tmpl_loop>

Will keep this in mind.

Just a different way of thinking about it, but you could always output all the rows and use html/css to hide the ones after #15 or whatever. That way you're a bit more in keeping with data/presentation split that HTML::Template enforces...

Knew I was missing something. Michael suggested in another post
HTML::Template::Expr, but I like the CSS method a little better.

Thanx.
