Re: HOw to pass parameters to the perl script?
Hi Almond, Along with what Bob suggested, you can also try using the module GetOpt::Long, too. It should be included in the standard distribution.

Re: another way to show results ?
Hi Ali,
I hope I understood your question correctly.
A user fills out a form, and you want the results to be displayed on the same page
(URL) ?
If that's the case, read up on subroutines. Subroutines are kind of like bins that
hold perl
code.
Here's some pseudocode:
if (some_condition){
run_subroutine_1
} else {
run_subroutine_2
}
sub run_subroutine_1 {
# do something
}
sub run_subroutine_2 {
# do something
}
run_subroutine_1 could display a form, for example.
And run_subroutine_2 could process those results.
All done on the same page.
HTH,
simon

Re: Newbie about STDIN
Hi Mark, the chomp function will take care of that problem for you. chomp removes carriage returns, if any, from the input. you might have also heard of chop which removes the last character of a string, which may or may not be a return. So, use chomp instead. #!/usr/local/bin/perl -w @array = STDIN; # or $scalar = STDIN; chomp @array; Hope that helps, Simon --- Mark Thumper Weisman [EMAIL PROTECTED] wrote: Hello List, I've got an easy one probably, however, I can't figure it out.

cgi script that takes in data then runs script on different host
Hi All, 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.

Re: Tables in CGI
Hiya Gerry, Is this db a relational database (like MySQL) ?? If so, have you heard of the DBI module? Using it, you can query the db and return the info in an array. Then, using a while loop, your script can determine how many TD's in the table to have. Like most of the other modules in Perl, the DBI module is quite well documented. Hope this helps. Try posting a snippet of what you've got and the rest of us can probably provide more specific help. ## --- Gerry Jones [EMAIL PROTECTED] wrote: I've been tormented by a very small problem. I'm trying to display the results of a database query using CGI. What I've done is create subroutines to return the names of the table columns and another to return the data, both of which are stored in seperate arrays. So I have my data, but the table just doesn't come out right. The problem is the arrays can be of different sizes, and I'm finding it really difficult to code a dynamic table using CGI. I could do it in pure HTML easily, but that's not the point: I'm trying to keep my code consistent. I've searched the 'net but the solutions I found didn't work.

Re: Question!! number of line....
Hiya Mark,
Something like this should work:
#!/usr/local/bin/perl -w
use strict;
my $file = file.txt;
open (READ, $file) || die Can\'t open file: $!;
my @list_of_words = READ;
close (READ) || die Can\'t close file: $!;
my $counter = 1;
foreach my $word (@list_of_words){
++$counter;
if ($word eq Apple){
my $counter2 = $counter;
last;
}
}
print Found \'Apple\' in line $counter2;
exit;
### Each cycle in the foreach loop increases the value of $counter by 1. When the
word is
located, the loop exited due to the last command. So, if the word is in line number
5, $counter
will have a value of 5.
I hope this helps.
Simon

options for the checkbox...?
Hi Everyone,
Let's say I have this snippet of code for a checkbox:
input type=checkbox name=bill
$name = param('bill');
If the box is checked, $name will have a value of on
If the box is NOT checked, $name will be undefined (have no value).
My Question:
Is there a way to make $name have a value of off when the box is UNCHECKED?
Many thanks for your time, Everyone.

param('$name') syntax......?
Hey Everybody,
I have the following code:
$k = 0;
foreach $item (@array){
print $item;
print qq{input type=checkbox name=$k};
++$k;
}
print qq{input type=hidden name=kvalue value=$k};
What is the proper syntax to see if the checkbox had been checked or not?
I've tried this:
my $check = param('$k');
if ($check eq on){
print check!;
}
Doesn't seem to work.
Many thanks for your time.

Re: sending @array as hidden variable
Curtis,
Your suggestion does not seem to work for me. My apologies for sending you the
script, but the
my @food = param('food'); does not work for me! Any and all suggestions would be much
appreciated.
here is the ovid1.cgi:
#!/usr/local/bin/perl
use CGI qw/:standard/;
print Content-type:text/html\n\n;
@food = (bread, ham, eggs);
print EndHTML;
form method=post action=http://cgi.sfu.ca/~skchan/cgi-bin/ovid2.cgi;
input type=submit value=click
EndHTML
foreach $item (@food){
print qq{input type=hidden name=food value=$item};
}
print /form;
And here is ovid2.cgi:
#!/usr/local/bin/perl
use strict;
use CGI qw/:standard/;
print Content-type:text/html\n\n;
ReadParse(*input);
my @array = param('food');
my $array;
foreach $array (@array){
print $array
print BR;}
### ReadParse #
sub ReadParse {
local (*in) = @_ if @_;
###reads the form inputs and sorts. DON'T CHANGE!!!
local ($i, $loc, $key, $val);
if ($ENV{'REQUEST_METHOD'} eq GET) { $in = $ENV{'QUERY_STRING'}; }
elsif ($ENV{'REQUEST_METHOD'} eq POST) {
read(STDIN,$in,$ENV{'CONTENT_LENGTH'});}
@in = split(//,$in);
foreach $i (0 .. $#in) {
$in[$i] =~ s/\+/ /g;
($key, $val) = split(/=/,$in[$i],2); # splits on the first =.
$key =~ s/%(..)/pack(c,hex($1))/ge;
$val =~ s/%(..)/pack(c,hex($1))/ge;
$in{$key} .= \0 if (defined($in{$key})); # \0 is the multiple separator
$in{$key} .= $val;
}
return 1; # just for fun

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 INPUT TYPE=\hidden\ NAME=\food\ VALUE=\$food\;
}
My two questions are:
1. Is this the most efficient way of sending an array as a hidden value?
Hello Simon,
What do you mean by 'efficiency'? You could mean most efficient in terms of
program speed,
bandwidth, or ease of use. I am assuming that you mean ease of use. If so, I would
say yes,
you have the most efficient method. However, it's not very robust. Consider the
following:
use strict;
my @array = ( 'Ovid', 'Fred Flintstone', 'Barney the wimp Rubble' );
foreach my $name ( @array ) {
print qq{INPUT TYPE=hidden NAME=name VALUE=$name\n};
}
In the above example, the HTML will be broken by the quotes marks embedded in Barney
Rubble's
name. To deal with that, use HTML::Entities. That will encode your data so it
doesn't mess up
your forms.
use strict;
use HTML::Entities;
my @array = ( 'Ovid', 'Fred Flintstone', 'Barney the wimp Rubble' );
foreach my $name ( @array ) {
$name = encode_entities( $name );
print qq{INPUT TYPE=hidden NAME=name VALUE=$name\n};
}
2. And if so, what is the corresponding $input{''} syntax?
use strict;
use CGI qw/:standard/;
my @food = param( 'food' );
Note that when using CGI.pm, the CGI::param function uses 'wantarray' to see if
you're expecting
a
scalar or an array returned. If you were to do this:
my $food = param( 'food' );
CGI.pm would only give you the first food item. Using '@food' gives you all foods
listed.
Cheers,
Curtis Poe
