text html from file to a scalar and mail
HI Folk,
May I introduce myself, John Plumridge, London, UK.
- I'm still in awe of this whole creation we're in.
Nice to meet you.
I have a reason of course, for approaching you, via my MTNews 'console'.
What a great application!
MY problem is obtaining and passing text/html from file to a scalar
variable to be printed to mail, (using MIME::Creator).
Unfortunately I get: 'printFile(FileHandle=GLOB(0x84b66b8))'
The reference assigned to the scalar variable is from a FileHandle sub
routine. However, with a similar reference to sub routines, i.e.
OrderFromForm_html(), I get the output printed to mail without a
problem. That sub routine is perl processed form data passed from a
preceding visible page in browser - 'form.html')
With mixed success then, I'v worked hard at this. Take a look:
###signature (html)from external file###
my $signature_file = /path_to/signature.html;
use FileHandle;
my $signature = new FileHandle;
$signature-open($signature_file)or die Could not open
file\n;
sub printFile($) {
my $fileHandle = $_[0];
while ($fileHandle) {
my $line = $_;
chomp($line);
print $line\n;
$fileHandle-close(); # automatically closes file
}
}
#---Assemble/concatenate references in both ascii and html, to make full
confirmatory message bodies with order details---
$scalar_sig = \printFile($signature);
my $customer_msg_html = $customer_msgStart_html . OrderFromForm_html()
. $customer_msgEnd_html . $scalar_sig;
# Create Message ---
Email::MIME-create(
attributes = {
content_type = text/html,
charset = UTF-8,
encoding = quoted-printable,
format = flowed,
},
body = $customer_msg_html,
),
So, as I suggested, the message arrives with the body message all nicely
concatenated , except for the $scalar_sig variable, which is moissing:
and I have the 'printFile(FileHandle=GLOB(0x84b66b8))' as a nice fat
error.
I would really appreciate your help, and outright suggestions, as I have
struggled with is and tests for three days now, (but I have got a lot of
the work done (: - though this problem has me stumped)!

Re: text html from file to a scalar and mail
Hi John!
Nice to meet you, and welcome to Perl. I'll try to answer as well as I can.
Note that I will also give you some general Perl best practices and links that
may not be a cause of the problems you are having.

Unfortunately I get: 'printFile(FileHandle=GLOB(0x84b66b8))'
This means it is a typeglob (a generic entry in the Perl 5 packages (=
namespaces)) that is blessed into the FileHandle class. Generally,
FileHandle is deprecated and you should use IO::Handle and friends instead.
The reference assigned to the scalar variable is from a FileHandle sub
routine. However, with a similar reference to sub routines, i.e.
OrderFromForm_html(), I get the output printed to mail without a
problem. That sub routine is perl processed form data passed from a
preceding visible page in browser - 'form.html')

my $signature_file = /path_to/signature.html;
It's nice that you're declaring your variables using my, but why don't you
have the use strict; and use warnings; pragmata? See:
* http://www.perlmonks.org/?node_id=111088
* http://perl-begin.org/tutorials/perl-for-newbies/part2/#page--my--DIR
In case, they were included, you should have placed them here, so we won't be
led into believing they were omitted from the original program.
use FileHandle;
my $signature = new FileHandle;
$signature-open($signature_file)or die Could not open
file\n;
You should use IO::Handle instead of File::Handle (or IO::File in your case),
and use the three args open. It's nice you've used die.
$signature is not a good name for a filehandle - better call it $signature_fh.
sub printFile($) {
Don't use prototypes.
my $fileHandle = $_[0];
Accessing $_[$idx] is not very robust - you should do:
my $fileHandle = shift;
Or:
my ($fileHandle) = @_;
while ($fileHandle) {
my $line = $_;
Just do:
while (my $line = $fileHandle) {
chomp($line);
print $line\n;
$fileHandle-close(); # automatically closes file
You shouldn't close the fileHandle inside the line reading loop, as you won't
be able to read from it further.
}
}
#---Assemble/concatenate references in both ascii and html, to make full

$scalar_sig = \printFile($signature);
Perl won't call printFile for you from within the string. Neither will the
print be returned to the string.
Please do:
my $scalar_sig = slurpFile($signature);
Look at http://search.cpan.org/dist/File-Slurp/ , and there are some other
modules on the CPAN that can do it. (like http://search.cpan.org/dist/IO-All/
).
my $customer_msg_html = $customer_msgStart_html . OrderFromForm_html()
. $customer_msgEnd_html . $scalar_sig;
Your style is inconsistent between camelCase, and
underscore_separated_identifiers.

Re: text html from file to a scalar and mail
From: Shlomi Fish shlo...@iglu.org.il use FileHandle; my $signature = new FileHandle; $signature-open($signature_file)or die Could not open file\n; You should use IO::Handle instead of File::Handle (or IO::File in your case), and use the three args open. It's nice you've used die. Nope. You should not be bothering with thatever class is at the moment behind the Perl filehandles and just use open() as a function. Not everything has to be an object open my $SIGNATURE, '', $signature_file or die Could not open '$signature_file': $^E\n; $signature is not a good name for a filehandle - better call it $signature_fh. I use all capitals for filehandles. Both oldstyle and lexical. my $fileHandle = $_[0]; Accessing $_[$idx] is not very robust - you should do: my $fileHandle = shift; Or: my ($fileHandle) = @_; Nope. Accessing $_[$idx] all over the place within the subroutine would be prone to errors and inconvenient (though sometimes necessary), what syntax do you use to copy the parameters into lexical variables is largely unimportant. And sometimes you can't just shift() off parameters from @_, you need to keep them there. my $customer_msg_html = $customer_msgStart_html . OrderFromForm_html() . $customer_msgEnd_html . $scalar_sig; Your style is inconsistent between camelCase, and underscore_separated_identifiers. Maybe there is a meaning to the underscores on some places and case change in others. Don't be so quick. The fact that you do not see a pattern from a very short example doesn't necessarily mean there isn't one. It may very well be too big to fit in the small cut hole that you see.
