RE: cgi script that takes in data then runs script on different host
First of all, don't cross-post please. One list is quite sufficient, and
many people are subscribed to more than one list, so duplicate messages
are quite often completely ignored.
I've got a cgi form that takes in data. Then, I want the
data to be passed to a script that's waiting on a DIFFERENT host.
So, say I have this pseudo-code:
cgi script on host 1pass $name to host 2 script on host 2
# get $name --- print
hi there $name!\n;
Could you pass $name in the query string? Like this:
--script 1--
#!/usr/bin/perl -w
use strict;
use CGI;
my $cgi = new CGI;
my %F = ();
# get all values passed to this script
# assuming no multi-valued form elements
$F{$_} = $cgi-param($_) for $cgi-param();
# rebuild the query string to stick on the
# end of whatever script you want to send
# these values to
my $query_string = '?';
$query_string .= $_=$F{$_}\ for keys %F;
my $host2 = 'http://www.host2.com/script.cgi';
print Location:$host2$query_string\n\n;
--end script 1--
--script 2--
#!/usr/bin/perl -w
use strict;
use CGI;
my $cgi = new CGI;
my %F = ();
# get all values passed to this script
# assuming no multi-valued form elements
$F{$_} = $cgi-param($_) for $cgi-param();
# print them to make sure they're there
print 'pre';
print \$F{$_} == $F{$_}\n for keys %F;
print '/pre';
# do stuff with the values passed to the first script
--end script 2--

you should try this. $old=abcdef; $new=lmnop; $ci_cmd1 = s/$old/$new/;#this substitutes the old value with the new one. regards, Ian David Gray wrote: Problem: ci_cmd1=abcdef, // line1 ci_cmd2=ghijk, // line2 ci_cmd3=lmnop, // line3 ci_cmd4=pqrst, // line4 I want to delete line 1 and 2 and the above should look like as shown below: ci_cmd1=lmnop, ci_cmd2=pqrst, Where are these lines?

RE: regular expression
code
for(@text) {
/(d+)$/; # Match only the numbers at the end of the string
^^
this should actually be (\d+)
I would actually conditionally print also, like so:
print $1 if /(\d+)$/;
And depending on the size of the file, instead of reading the whole
thing into memory with
my @text = (FILE);
I would do:
while(FILE) {
print $1 if /(\d+)$/;
}
# and store them in '$1' to be printed out on the
# next line followed by a new line character
@text # contains values of a phone directory
$text[0] contains john=012345678
$phone1 = ?
let say i wanted to grab just the values'012345678'.
how should i go on truncating the values?
Cheers,

RE: pass values to another scipt
Hi Sven, Sorry, I thought you knew that one. But how to proceed if you don't want those ugly/insecure params in your location bar ? Use a form and an input type=image HTH, -dave -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: CGI and frames
Sorry, I chose the wrong words.. my script works similar to the way you described below. Depending on which fields are filled out and which button is pressed, a different subroutine is called, creating the page. Ok... Could you post some code or pseudocode that describes the problem you're trying to solve? -dave -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: a href Vs Form post
I am strugling with my program that list the contents of a directory. Ones the directory contains files and you have permission it shows you a doc icon else it will show a directory-map followed by it's name as an a href The problem I have now is that using the a href command will have to show all important variables in the browsers Location. Of course, you would say. But is there a nice possibility to keep using the a href statement without defining the variables in the href, So I can work with the : use CGI qw(:standard); $userid = param(userid); ... And get the variables without all users seeing what I need ? Using the input type=submit, always generates a button, (I believe), that is what I don't like to have, 20 dirs, with 20 different submit buttons. Does anyone have an idea ? Maybe you could use one big form and have a checkbox by each directory instead of having twenty forms. Many Thanks in advance !!! Location example: http://stage-www/cgi-bin/david/index.cgi?base=/user/web/apache /stage/htdocs/david/IPlab?header=IPlab?pwuser=gaard?group=icgrp That URL won't work for us because we're not local to your network...

RE: exiting correctly
below is a snipet of the code. the most relavant part. when
i enter some bad data in or mysql has problems, it should go
to error_handler() at the bottom of my script. well it
does, then it returns unless i put an exit at the end of
error_handler.
How about:
mysub('param1','param2');
mysub('parma1','param2');
sub mysub {
my ($p1,$p2) = @_;
print in mysub\n;
$p1 eq 'param1' or err_h(invalid param: [$p1]\n) or return 0;
print passed: [$p1] [$p2]\n;
}
sub err_h {
print $_[0] and return 0;
}

RE: asp from perl
hello everyone,i am trying to execute an asp script from a
perl cgi and i have the following problem
I am using something like this to get user's input and the
pass it to the asp
ReadParse (*input);
my $pin;
my $passwd;
my @input;
$pin = $input {'pin'};
$passwd = $input {'passwd'};
my $page_url = 10.0.0.4/Validation.asp?pin=$pinpasswd=$passwd;
the problem that i seem to be having is that i can not get
the values passed to the asp in the form of
variables,because the values of $pin and $passwd are no
actually being passed to the asp..,therefore it gives back
an empty answer Does anoyone knows how to pass the actual
variables values to the asp?
Check out the cgi module:
perldoc cgi
You're gonna want to do something like:
use CGI;
my $cgi = new CGI;
for($cgi-param()) {
$F{$_} = $cgi-param($_);
}
Watch out for multivalued form inputs though. This is covered in the
CGI.pm documentation.
Hope that helps a bit,

RE: Read in from STDIN
Could anyone help I am having trouble reading in information from STDIN For coding see attached file Using a while loop I want to do the following: Read info in from STDIN Read in any number of name/value pairs, Read in names in pairs of two, and compute their sum. Choose the maximum of all those pairs and print it. At the same time choose the minimum and print it. Your code looks fine to me - what exactly is going wrong? How are you giving the data to STDIN (you do know that you have to hit enter each time you want STDIN to read what you've typed, right?)? -dave -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Internal server error
I'm having problems with the old Internal Server Error issue. I know that this is generally due to permissions. I have used chmod go+rx -R *, but no joy. The html now works but not the cgi. Thoughts? Try inserting the line use CGI::Carp (fatalsToBrowser); At the beginning of your script. And try running it from the command line.

David You can check $ENV{REMOTE_ADDR}, which will contain

David of the user hitting your page.
And that's still insufficient and incorrect.
Repeat after me:
A user is not an IP address
A user is not an IP address
A user is not an IP address
Specifically, the largest userbase on the planet, AOL, comes
into the Internet proper via Web Proxies. On every hit, a
different proxy is used, so these hits show up as coming from
completely different addresses. Even the main page and the
image fetches for that page will all show up as different
addresses. And then of course, those same
small-number-of-proxies are used for millions of users.
So again, I repeat:
A user is not an IP address
Get it through your head that using IP address for vote
blockout is just ... WRONG.
Message received, ZERO distortion. Are you saying, then, that it's
impossible to build an accessible cgi-based voting system (which allows
more than one user to access the system from within a large network)
without using cookies or forcing each user to log in?
