[htmltmpl] New Template Object based on Existing one

[Chris F. <cf...@do...>]

Hey All,

I haven't seen a message posted since the 21st, so I wanted to make sure =
everything was still working :)

Seriously, this may be a silly or even stupid question - but is there =
some way to create a new template object and simply assign it all the =
params as a existing template object?

Something like
****
my $content =3D new HTML::Template(filename =3D> "template1.tmpl");

Go through and set all kinds of params

my $content2 =3D new HTML::Template(filename =3D> "template2.tmpl");

$content2->param(%$content);

$content2 now contains all the params and values that were/are in =
$content.
****

I know that wouldn't work, just hoping it would help explain.

Thanks
-Chris

I haven't tried this, but my first reaction is to use the usual syntax
for interrogating a template:

$content2->param($content->param);

Thanks Roger, I'll give that a try and see what happens.

It's even simpler: simply associate the first object with the second.

#!/usr/bin/perl
use HTML::Template;

my $tmpl =3D new HTML::Template filehandle =3D> \*DATA;
$tmpl->param(foo =3D> "bar");
print $tmpl->output;

my $str =3D "Second template: foo =3D <TMPL_VAR NAME=3Dfoo>\n";
my $copy =3D new HTML::Template scalarref =3D> \$str, associate =3D> =
$tmpl;
print $copy->output;

__END__
First Template: foo =3D <TMPL_VAR NAME=3Dfoo>
=3Dcut

will print:

$ perl associate.pl
First Template: foo =3D bar
Second template: foo =3D bar

Thanks for the suggestions guys, I tried both ways and I got different
results with each.

That "associate" seemed like the way to go, when I tried that I get the H:T
error
"attempt to set parameter 'items_loop' with a scalar - parameter is not a
TMPL_VAR!"

When I tried the "$content2->param($content->param);" method - I'm not
really sure what happened, it failed when trying to set a tmpl_var that was
the "else" in $content, but $content already contained the flag to mark that
value true, plus it seemed to process forever, it took about 2 mins..

I'm going to keep experimenting and see if I can get something to work, if
you have any other idea, I'd love to hear them.

Thanks

Hello Chris,

I think that this can be done more simply:

my $copy = new HTML::Template associate => $tmpl;

but if I'm not mistaken, when you will call $tmpl->param(foo => 'bar')
later, you'll get this param also in $copy

Interesting.  I've never tried to associate one template with another
one, but I would expect it to work.  Can you put together a small test
script that generates this error?

> When I tried the "$content2->param($content->param);" method

That won't work because param() without any args returns a list of
parameter names, no values.  Try something like this:

  $content2->param(map { ($_, $content->param($_)) } $content->param());

That takes a list of param names and uses map{} to build a list of
(name,value) pairs to pass to param().

Doh!! I appear to be all set Sam..

I couldn't easily take my existing code out as an example as its spread
across 2 modules so I spent a few mins creating a test script. When I
finished, it worked just fine..

To make a long story short, the loop wasn't being properly defined due to a
earlier change, the "associate" had nothing to do with it - I just had a
brain lapse between making a change and trying to get something new to work.

Sorry about that, but hey... Its working now :)..

I'm using Sebastien's suggestion of:
my $t2 = new HTML::Template(filename  => "email_purchase_results.tmpl",
                                                   associate  => $t1,
           );

I have a bunch of places where (like a shopping cart) the user is selecting
multiple things through multiple form pages, once its done and everything is
displayed to the user for conformation/receipt, I have to email it to
multiple parties (again like a shopping cart).

Using the above I can now have multiple email templates which I can assign
all the values of what was just displayed, add some params if needed etc..
and just send it off as a HTML email...
No more logic and nothing more then a couple of extra lines of code to do
emails!!

Maybe nothing special to some, or should have been obvious to me - but I
wish I figured this out about a year ago as I would have saved hours upon
hours of specialized email creation code, never mind about 5000 db hits a
day that I will just go away!!

Sam, you're the man.. H::T is awesome!!

Thanks
-Chris
