Sorry! I meant my population, as in the users of this program.  This is only

anyone not in our member roster will be tossed out.  My college career

everyone who needs to be on the CD has a word resume.  I did not mean to
imply that 100% of the world had their resumes in Word format!  My mistake.

sending @array as hidden variable

2001-08-23 Thread Simon K. Chan

Hi Everybody,

I am trying to send an array as a hidden value in my script as follows:

@array = (eggs, ham, bread, pop);

foreach $food (@array){
print "";
}

My two questions are:

1.  Is this the most efficient way of sending an array as a hidden value?

2.  And if so, what is the corresponding $input{''} syntax?

Many thanks for your time, everybody!

Vance,

It sounds like that could be the problem.  Generally, when printing a Web page from a 
CGI script,
you need to supply a content-type header to let the user agent (browser, in this case) 
know what
type of content it's dealing with.  If you're not doing that, your Web server might be 
doing that
for you and sending a default of 'text/plain', or perhaps it's not sending it at all 
the the
browsers are using defaults?  Tough to say what's going on here.

If you are not printing anything before the Web page, try printing the following:

print "Content-type: text/html\n\n";

That will add the content-type header.

Even better, try this (tougher to make a typo with this method):

use CGI qw/:standard/;
print header();

It sounds like you may be a little unsure as to what is meant by headers, so I'll try 
to explain,
just in case.

Your browser, when you request a resource from a Web server, will issue a request.  
There are many
different request methods, but for CGI programmers, you will primarily be dealing with 
GET and
POST requests.  A typical request sent from your browser to the server may resemble 
the following:

POST /cgi-bin/somescript.cgi HTTP/1.1
Accept */*
Accept-Language: en-us
Accept-encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)
Host: www.someserver.com
Connection: Keep-Alive

color=red&name=Ovid

Note that this request is split into two sections.  The first section is comprised of 
the headers
and the second section is the "entity body", or just "body".  Since this is a POST 
request (see
first line), "form" data is put in the entity body.  If this were a GET request, there 
would be no
body and the first line would be something like (note the query string moved from the 
body)

GET /cgi-bin/somescript.cgi?color=red&name=Ovid HTTP/1.1

For a get request like the one above, you'll see something like the following in the 
address bar
of your browser:

http://www.someserver.com/cgi-bin/somescript.cgi?color=red&name=Ovid

The Web server receives the request and passes your query information to the CGI 
script.  When the
CGI script responds, it is expected to send at least a Content-type header (unless 
your using
non-parsed header scripts, which I won't go into now) or a status header (which I also 
won't go
into now).  Your Web server supplies the rest of the headers.  Here's a typical 
response:  a Web
page sent by a script:

HTTP/1.1 200 OK
Date:  Thu, 23 Sep 2001 06:23:19 GMT
Server: Apache/1.3.6 (Unix)
Last-Modified: Mon, 20 Sep 2001 08:19:56 GMT
ETag: "2f5cd-9640381-e1bd6"
Accept-Ranges: bytes
Content-length:  4295
Connection: close
Content-type: text/html




base-02.html
etc.

Note that we again have headers and a body, just as an HTML document has a head and 
body, but
we're talking apples and oranges here.  Your script is expected to at least specify the
content-type (note the last line of the headers) and the Web server usually provides 
the rest of
the headers.  The two newlines between the headers allows your browser to know where 
the headers
stop and the entity-body begins.  Typically, when you "view source" in a Web browser, 
you're
seeing *only the entity-body* of the document that's been returned.

Hope this clears up the confusion.  For more information, you can read

Actually, that's the head of the HTML document.  What's needed are the headers that 
are sent
*prior* to that.  Those headers tell the user agent (the browser, in this case) what 
to do with
the document.

sendmail and newlines

2001-08-23 Thread Wendy DeCora

Situation:  My perl script (see Code: below) is being
handed a flatfile (see File: below) generated from a
database to do a mass mailing that will send a message
generic to the flatfile but with each recepient
receiving a unique username and password.
The message part of the file is being input by a list
administrator through an oracle tool (I think, I
didn't develop that in anyway) and the ability to have
newlines is necessary for formatting.  The problem is
when this message is dumped into the flatfile, the
newlines are still in it and cause the script to go
nuts.

My idea was to have the newlines in the message
replaced with \\n before being put into the flatfile
(which is what I have done in my test file).  I then
attempt to replace the \\n with \n in the $message
field for sending.

It kind of works. (see Output: below) I get the
newlines now, but i also get one \ just out there.  I
have tried many variations, but having \\n and
replacing with \n seems to be the only way to get a
newline to work, but how to get rid of the extra \?

Any suggestions would be very very appreciated.
TIA

Code:
#!/usr/bin/perl
$mailprog = '/usr/sbin/sendmail -t';
$admin_email="decoraw\@act.org";
$subject="Testing the new mass mailer";
$file =
"/actapps/suitespot/cgi-bin/sender/returntest3.txt";
$number_sent = 0;
open(DATA, "$file") || die "Can't open $file";  # open
the file for reading

while($line = )
{
chomp $line;
($junk,$email,$message,$survey_url,$login,$password)
= split(/\|/,$line);

$message =~ s|\\n|\n|g;  #replace the escaped
newlines with newlines for formatting

open (MAIL, "|$mailprog -t") || die "Can't open
$mailprog! \n";
print MAIL "Content-type:text/plain\n";
print MAIL "From: $admin_email\n";
print MAIL "To: $email\n";
print MAIL "Subject: $subject\n";

There are a few ways to do it.

Easiest is to have the config file be valid perl, and call it
like:

require "/path/to/config.pl";

There are plenty of modules on CPAN to read config files; my
favorite is Config::General, which allows for (among other
things) Apache-style config files.  Config::Ini is also supposed
to be good, and there is also the AppConfig package.

RE: Browser Problem

2001-08-23 Thread Bradley M. Handy

Check any 'Content-type' header that you send.  The header should be
'Content-type: text/html'.  If you are not sending a 'Content-type' header,
then you should be.  To do this simply put one of the following statements
in your code:

# if you are using Lincoln Stein's CGI.pm module.
print CGI->header();

or

# if you are NOT using Lincoln Stein's CGI.pm module.
print "Content-type: text/html\n\n";

The reason the HTML is being read as plain text, is due to the fact Netscape
and Opera are being the content is 'Content-type: text/plain'.

Newer versions of Internet Explorer have a "feature" that examines that beginning of 
the data that
it receives and attempts to render the data accordingly.  It completely violates W3C 
standards by
ignoring the content-type header.  Many, many developers have been bitten by this bug. 
 I've
accidently sent GIFs with a content type of image/pjpeg and IE still rendered it 
correctly but
Netscape didn't.  That was less than fun to debug.

In your script, find out what is responsible for printing the content-type header and 
post that
code snippet here.  It will be something like the following:

# If you're doing it by hand, it will resemble this:
print "Content-type: text/html\n\n"; 

# If you're using CGI.pm, it will resemble on of the two following lines:
print header();
# or (varies depending on the name of the CGI object)
print $query->header;

There are many different ways of printing the content-type header, but they will 
likely resemble
the snippets above.  Send that and we may have an answer for you.

Of course, you can also telnet to port 80 (assuming that's the telnet port) and view 
the headers
that way).  Most likely, you're sending a content type of 'text/plain'.  Here's what

RE: CGI::POST_MAX use and control

2001-08-23 Thread John

John,

Thanks for the idea.

I'd thought of using JavaScript, but I'm sunk if the user has Jscript turned
off on their PC and I felt I wanted a little more surety on this being
checked. I am going to re-visit the idea, however.

My current Perl code does catch the error and return a form to the user so
that they can reflect on their evil ways and correct their misdeeds. The
script won't abort on 'em. (I'm considering a file-based counter, so that
maybe the third time the same user flubs up I can really slap their paw,
however; but that's an "enhancement" )

Thanks.

A simple JavaScript to check for the max size of a textarea and an "alert"

In general, you always want to die gracefully from within a web script so
the error is logged and the user doesn't get an icky 500 error page.

For example, in database apps I write, for any error, I tell the user the
database is unavailable and I log the error.

The following has worked for me when dealing with POST_MAX:

use CGI qw/:standard/;
$CGI::POST_MAX=1024 * 10;
$CGI::DISABLE_UPLOADS = 1;
$| = 1;

my $page = new CGI;

print $page->header;

$run = $page->param('RUN');
if (!$run && cgi_error()) {
# do whatever you do for an error
&dieWell ("413: Max Posting surpassed.");
}

sub dieWell  {
my $message = shift;
# remember to print proper headers if not done by now
print "$thanks_for_playing_message\n";
# do logging of $message if you want, send yourself email, whatever
&footer;  # end my html -

maybe you've made a mistake with your HTTP headers which IE5.5 is being

Can you check the headers that you are producing and post them to the group?

RE: CGI::POST_MAX use and control

2001-08-23 Thread John

Lisa,

Thanks!

I synthesized from your answer and realized that my use of 'use CGI::Carp
qw/fatalsToBrowser/;' was having me die long before I could have the code
handle the problem. I commented out the '...Carp...' block and, indeed, my
builtin code handled the error the way I'd intended.

I was even able to see my 'friendly' ;-) user's error message: "Because your
message was too long, we ran out of electrons. Please shorten your e-mail
message.". When I shortened the message to less than the 4K I spec'd, the
form and code did the right thing and produced the intended e-mail.

Follow-up question: Does POST_MAX measure the length of the incoming stream
as the code asks for it -- $recd_data = $form->param('sent_data'); -- and
then pulls the plug if 'sent_data' goes outside the bounds of acceptable
social behavior?

I ask because, while this change worked in my current program, I want to
more fully understand the working principles for my next system.

Thanks.

Basically, if it has to do with Perl/CGI , then it is allowed. If your
question has nothing at all to do with Perl/CGI, it will likely be
ignored.

  2.5 - I want to help, what should I do?

Subscribe to the list! If you see a question which you can give an
idiomatic and Good answer to, answer away! If you do not know the
answer, wait for someone to answer, and learn a little.

  2.6 - Is there anything I should keep in mind while answering?

We don't want to see 'RTFM'. That isn't very helpful. Instead, guide the
beginner to the place in the FM they should R :)

  2.7 - I don't want to post a question if it is in an FAQ. Where should I
look first?

Look in the FAQ! Get acquainted with the 'perldoc' utility, and use it.
It can save everyone time if you look in the Perl FAQs first, instead of
having a list of people refer you to the Perl FAQs :) You can learn
about 'perldoc' by typing:

`perldoc perldoc'

At your command prompt. You can also view documentation online at:

http://www.perldoc.com and http://www.perl.com

* Perl Home Page - http://www.perl.com
* PerlMonks - http://www.perlmonks.org
* Perldoc - http://www.perldoc.com
* Perl Archives - http://www.perlarchives.com
  3.2 - What resources may be harmful to a beginner?

Anything having to do with the names Matt Wright, or Selena Sol. Why?
You may ask yourself. Well, their scripts are old and have been known to
be buggy, as well as have security issues. They were written in the days
of Perl 4. This means there is no scoping, stricture, warnings, idioms,

By default WS_ftp will only be expecting files with certain extensions (eg.

binary. You can change these defaults on the Options button, Extensions tab.

When I tried it out, the program still crashed.  It executes most of the code, 
up to the (paraphrased)

$file = $cgi->get_upload(blah)

then stops executing.  

I think maybe I can do something with .htaccess files to adjust the limit on 
PUT, but that is a bit too OT for here, I think.

CGI::POST_MAX use and control

2001-08-23 Thread John

Hi all,

I would appreciate some guidance in the use of CGI::POST_MAX. I've listed a
snippet of relevant code below from my program to illustrate.

When reading in data fields from an HTML form, I want to limit the size of
the data accepted from a TEXTAREA box. I don't want to depend upon my ISPs
timeouts and what-nots to stop a user from trying a DDOS on 'em.

The current incarnation of my script blows itself out of the water if the
$user_body variable (the TEXTAREA source) is greater than 4K, for example.
This is good.

I would like to be able to capture and control the process so that I don't
get rudely blown out of the water with a crude 500 Server message (this
would be gooder! ). I would like to: a)generate a useful message and, b)
set some flags, do some more processing, and send a message back to the user
to give them an opportunity to correct their input and atone for their sins.
(This would be more gooder! )

I've read through the CGI.pm writeup, but I don't believe I'm applying it
correctly. I am having a problem understanding just how and where to make
use of CGI::POST_MAX, CGI::Carp, and probably cgi_error() in my code. Where
do I put 'em and can someone demonstrate with a similar snippet of code just
how and where these are used? For example, when this bombs with data > 4096
bytes, I don't even see an error message in my error log file,
...cgi-log.txt -- that would be a nice diagnostic help, too.

If there is another prefered method to limit size of input, I would
appreciate learning about that, too!

Right now my code produces an 'accurate' result (a nuke will 'accurately'
kill a fly), but I would prefer to have it produce a 'precise' result
(perhaps a HOW-TO on using tightly focused gamma rays to zap that fly,
instead). It works, but its not elegant.

I'm looking for the state of "most goodliness". 

(My apologies to non-native English readers of this list for my having fun
with the language, but its been a tough day...)

Thanks, all.

What do you mean by "then quits"?  Does it silently fail?  Does it hang?  Does it 
return an error
message?

Wild guess:  Recently (like, two days ago), I had a problem with a script that worked 
fine on a
Windows box but then mysteriously 'hung' on a Linux box.  It was caused by the same 
problem that I
had for my recent question about my script dying when I turned off warnings:  Windows 
and Unix
have different line endings.  Since you mentioned that you had successfully run this 
on a Win98
box, I'm wondering if this is the problem.

Windows recognizes \12\15 as the end of line characters (\r\n).  Unix is looking for a 
\15 (\n). 
If you have shell access to your server, enter the following:

cat -vet script.cgi | more

This will display the end of line characters as a dollar sign.  If you see a ^M before 
the dollar
sign, then you know you have DOS line endings.  Here's an example:

#!/usr/bin/perl -wT^M$

If you see that ^M, (ctrl-M, a.k.a. ASCII 12, a.k.a. \r), you can eliminate it with 
the following
in-place edit:

perl -pi -e 's/\r//g' script.cgi

Just make sure to back up your script, first.

To prevent this in the future, make sure you FTP your scripts to the server in ASCII 
mode, not
binary.  ASCII mode will fix the line endings for you.

If this doesn't resolve the problem, let us know.

Cheers,
Curtis Poe
