Re: Making a Copy of a template object

Thanks Sébastien, Damien and Michael.
 
I'm really trying to split the current template object into 2 different objects after I've assigned a bunch of things to it (one ends up being for display and the other gets emailed), so I guess I should check out that storable module as if I just invoked the "new" method again I would have to reassign everything again to the new object, right?
 
Thanks!
-Chris

Hi Chris,

Where you have the statement:

$template2 = $template ;

Essentially what you are doing here is creating a variable $template2 that points to the same object as referenced by $template.  An object in perl is a blessed reference and so you have just made a copy of a reference.  So $template2 and $template point to the same object.  

If you wish to make a true copy of the object, you will need to look at things like Data::Dumper or better still the Storage module which has freeze and thaw subroutines.  Hopefully this will achieve what you want.

All the best.

Regards,
Damien.

	Folks,
	
	I'm trying to create 2 different vars from the same template object and it appears once I do so that whatever I set in one gets set in the other. What am I missing? Is it because I'm creating a reference? (I didn't think that was the case).
	
	Here is an example of what I mean
	
	my $template_object = qq|<TMPL_IF NAME="Var1"> Var 1 is set</TMPL_IF><TMPL_IF NAME="Var2"> Var 2 is set</TMPL_IF>|;
	
	my $template = HTML::Template->new(scalarref    => \$template_object);
	 
	$template->param(Var1   =>      1);
	
	my $template2 = $template;
	
	$template2->param(Var2  =>      1);
	 
	print $template->output();
	 
	The output I get is: "Var 1 is set Var 2 is set" even though I set "Var2" only in $template2 only
	 
	 
	TIA!
	-Chris
