[htmltmpl] bug parsing ESCAPE='URL'

[Paul B. <pb...@wh...>]

I found a bug in the latest version of HTML::Template (2.6 and at least  
also 2.5) where if you have escape='url' in a <tmpl_var> tag, HTML  
escaping is done instead.

This happens because although the main parsing regex checks for double  
and single quotes around url, later when another regex  is used to test  
if an HTML escape or URL escape was used, it only checks for ESCAPE=URL  
or ESCAPE="URL". So if you have ESCAPE='URL' it is treated as though  
the default HTML escaping was specified. I submitted a patch for this  
on SourceForge last week, but since there hasn't been any activity, I  
thought I should post to the mailing list as well.

The url for the patch tracker entry is:

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

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().

Re[2]: [htmltmpl] New Template Object based on Existing one

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

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

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";

$tmpl;
print $copy->output;

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

[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

[htmltmpl] loop iterations count

[<hat...@tu...>]

Hello html-template-users,

  I wonder if there is a possibility to get the count of iterations
  in a loop.

  <TMPL_VAR __counter__> returns the number of current iteration.

  of course, I know that I always can do param() to put this into a
  template, but may be there is an other way...

A perl script can have a "data" section, anything that follows the __DATA__ tag in the script file. The part with \*DATA is a reference filehandle to that data section.  Its a nifty little trick that I use to test out templates in the same file as a script.

Re: [htmltmpl] TMPL_VAR inside a TMPL_VAR

[LDT <per...@ya...>]

Thanks for the reply, Ron.  I'll try to answer your questions.  I ended up just using a TMPL_INCLUDE to handle it since it was taking me so long to figure it out (and the reports are due 2-1-04, and this is just the first one).  However, I really appreciate your taking the time to explain to me why it didn't work.  That helps me (and future folks searching the archives) to understand how things like TMPL_VAR work.
 
I already had global_vars set to 1 (I think I had snipped that out in my first post - my bad).  My goal was the take a scalar ($cell_fmt) and pass it to the main template.  However, the $cell_fmt scalar had a TMPL_VAR inside it, and I learned that H:T won't interpret it in "layers" (which prompted my initial post).  The "big_tmpl" stuff was something I was trying that someone else had suggested but I didn't understand him.  I ended up deleting all the "big_tmpl" stuff, and going with the TMPL_INCLUDE.
 
I had tried to add the $cell_fmt to my @loop_data (which is fed into the TMPL_LOOP on the main template), but it didn't like that either (undoubtedly it was the way I was trying to add it).  I am curious about this piece of your code:  filehandle => \*DATA.  What does this do?  The parts I understand are that you're setting up file handle, the "\" is a reference, and the "DATA" is referenced to the section below.  My guess would be that this is how you're passing the formatting stuff to the template.  Is that right?
 
I'm not trying to correlate the two arrays in the template.  The @loop_attr actually goes into one of the main template's TMPL_INCLUDEs (and then into it's own TMPL_LOOP) and really has nothing to do with @loop_data (they each have their own TMPL_LOOP).
 
The final .pl code is about 450 lines; the templates all total are about 100 lines.  If you want to see it, let me know and I'll send it.  Thanks again for taking the time to help me!

[htmltmpl] Delphi Comp?

Hi all,

I'm looking for a Delphi component similar to H::T. I found 'HTML Template'
but I don't really care for it. I'm looking for something that is flexible
in terms of where the data comes from, and of course, open source. The RAVE

this as well.

$tmpl_main only gets parameters that are visible inside $cell_fmt. Once 
those are set, you can put its output into the parameter of another 
template like this:

my $big_tmpl = HTML::Template->new( . . . );
$big_tmpl->param( some_var => $tmpl_main->output() );

$tmpl_main only gets parameters that are visible inside $cell_fmt.  Once 
those are set, you can put its output into the parameter of another 
template like this:

my $big_tmpl = HTML::Template->new( . . . );
$big_tmpl->param( some_var => $tmpl_main->output() );

I had snipped out the parameters in my original post because they were irrelevant, but now it trips over them in my actual program.  I haven't changed any of my templates, so I believe this is in response to the scalarref stuff I'm trying to do.
nc_rpt_summary.pl: HTML::Template : Attempt to set nonexistent parameter 'title_bar' - this parameter name doesn't match any declarations in the template file : (die_on_bad_params => 1) at /local/www/htdocs/scripts/campus/nc_rpt_summary.pl line 594 
And here's the complete code section I'm using (I went back to the HERE doc, but the q and qq don't work either):

my $cell_fmt = <<EOL
align="right" style="cursor:pointer;cursor:hand;" 
                      title="Click to drill down"
                      onmouseover="style.background='#CCCCFF';" 
                      onmouseout ="style.background='<TMPL_VAR NAME=bgcolor>';">
EOL
;

$tmpl_main = HTML::Template->new( scalarref => \$cell_fmt );
$tmpl_main->param(  title_bar  => "Rpt $rpt_no - $rpt_lbl",
                    hdr_asofdt => "$rpt_asofdt",
                    attr_fyr   => $attr_fyr,
                    passattrs  => \@loop_attr,
                    passdata   => \@loop_data);
print $tmpl_main->output();

I also tried changing the order of the parameters passing to the template, but that didn't make it work (I tried putting the "new" after "param").

BTW, your <TMPL_INCLUDE> suggestion will work, and I'll use that if I can't get this to work.  I wanted to try and avoid the TMPL_INCLUDE because I end up with a reference/link inside of a reference/link (and I'll have another reference/link in the future when I get the drill down set up) and I want to keep my code as maintainable (and readable) as possible.  Or, am I being too picky?

scalarref takes just that:  a reference to a scalar.  So you almost got it:

$tmpl_main = HTML::Template->new( scalarref => \$cell_fmt );

Re: [htmltmpl] TMPL_VAR inside a TMPL_VAR

[LDT <per...@ya...>]

Hi Timm,
 
Thanks for the quick response.  I looked at the H:T documentation, and I see the reference to scalarref and arrayref, but I don't understand what they mean or exactly how I might use them.  If I understand your note correctly, I would need add the scalarref like this:
 
my $cell_fmt = qq (align="right" style="cursor:pointer;cursor:hand;" 
                      title="Click to drill down"
                      onmouseover="style.background='#CCCCFF';" 
                      onmouseout ="style.background='<TMPL_VAR NAME=bgcolor>';">
                  );

$tmpl_main = HTML::Template->new( scalarref => $cell_fmt );

 
However, I get the following error:  "nc_rpt_summary.pl: Can't use string ("align="right" style="cursor:poin") as a SCALAR ref while "strict refs" in use at /usr/local/lib/perl5.8.0/site_perl/HTML/Template.pm line 1597."
 
I've also tried using just a "q", using a HERE doc, and I get pretty much the same error each time.  So, obviously, I'm using it incorrectly but I don't understand why.  Any ideas?  If you're willing, would you give me a dumbed down version?  ;-)
 
Thanks!

HTML::Template won't expand entries that were placed into 
another . What you probably want is a 
. Alternatively, you can create another HTML::Template 
object out of the data inlined in your program now via the scalarref 
parameter. You can fill in this data as normal, and then pass its output 
to the main template's .

HTML::Template won't expand <TMPL_VAR> entries that were placed into 
another <TMPL_VAR>.  What you probably want is a 
<TMPL_INCLUDE>.  Alternatively, you can create another HTML::Template 
object out of the data inlined in your program now via the scalarref

[htmltmpl] TMPL_VAR inside a TMPL_VAR

[LDT <per...@ya...>]

I'm running into an error when trying to pass a TMPL_VAR inside a TMPL_VAR and have it be evaluated.  I've set global_vars = 1, so I was thinking that would help.  I've included the pieces of my program, template and output.  As you can see, most of the TMP_VARs are evaluated/passed, but the internal TMPL_VAR isn't (although it's also the same "bgcolor" variable used in the <tr> line, which I highlighted in bold below.  
 
Am I missing something, or am I trying to do something naughty? 
 
Within my main program:
 
#set up format parameter for data cells in summary report
my $cell_fmt = <<EOL
  align="right" 
  style="cursor:pointer;cursor:hand;" 
  title="Click to drill down"
  onmouseover="style.background='#CCCCFF';" 
  onmouseout ="style.background='<TMPL_VAR NAME=bgcolor>';">
EOL
;

#Pass parameters to template; print report
$tmpl_main->param(  cell_fmt   => $cell_fmt,
                    passdata   => \@loop_data);
print $tmpl_main->output();

Within my template:
 
<TMPL_LOOP NAME=passdata>
    <tr class=<TMPL_VAR NAME=trclass> bgcolor=<TMPL_VAR NAME=bgcolor>>
    <td <TMPL_VAR NAME=cell_fmt><TMPL_VAR NAME=col_cfte></td>


The relevant section of the results when I view the source of the page (after the "invalid argument" errors):
 
<tr class=normal bgcolor=#FFFFFF>
<td align="right" style="cursor:pointer;cursor:hand;" 
                  title="Click to drill down"
                  onmouseover="style.background='#CCCCFF';" 
                  onmouseout ="style.background='<TMPL_VAR NAME=bgcolor>';">
<font color=#000000>$12,345.67</td>

The main template would get the data that was in the included template when 
you called output() on the included one.

Re: [htmltmpl] Dynamically including templates?

[Todd C. <htm...@ch...>]

If TMPL_INCLUDE is processed first, does that mean
I can't do this? (Using HTML::Template::Expr)

<TMPL_IF EXPR="include_param = 'x'">
	<TMPL_INCLUDE NAME="<TMPL_VAR NAME=x>"
</TMPL_IF>

Re: [htmltmpl] Dynamically including templates?

[Todd C. <htm...@ch...>]

Using the method described below, do I have to set
the params in the appropriate teamplates, or can I
do the include first and set all the params in one
template? The reason I ask is that the params all
come from one database table, and I don't want
to worry about which template has which TMPL_VARs.

Thanks.

Re: [htmltmpl] Dynamically including templates?

[Jason P. <ja...@jo...>]

My guess is that it's trying to do the INCLUDE *BEFORE* doing the 
variable substitution.

So if you're stuck on making the included file dynamic, I would 
recommend a two-sweep approach, which I see Timm Murray's post addresses.

Cheers,

Jason
