use_named_parameters()

Hi, I have this problem and don't immediately know the sollution. I would like perl to use named parameters only while doing cgi scripting. To force this I use the following code: #!/opt/bin/perl -Tw use CGI; use strict; my $q = CGI->new(); $q->use_named_parameters(1); etc... However, it do

How to get the biggest integers from an array?

Hiya, I'm in search for a solution. Let's say I have this array: @array (5, 6, 7, 89, 1, 0, 456, 298023, 56); Now, how can I get the biggest integers from this array and give them a string with their place. Let's say I have a foreach loop where I checked all the biggest integers (however, I do

RE: use_named_parameters()

The method has been removed. From the docs: Version 2.57 6. Removed use_named_parameters() because of dependency problems and general lameness. http://stein.cshl.org/WWW/software/CGI/ I think "param" is now the preferred method. http://danconia.org

Installing CGI.pm in RedHat 8.0.

I dont know why, in my OTHER RedHat 8.0 installation, I cant find CGI.pm. I did install perl5.8.0. Anyone know how to install it? I looked in cpan, it seems it's default perl module. And I cant find any installer for it. Is it OK if I just copy CGI.pm from cpan? into /usr/lib/perl5/5.8.0/CGI.

Regular Expression

Hello, I have this regular expression: $List =~ /^(?:(\d+)\*)?(\w+)\/(?:(\d+)\*)?(\w+)$/; It checks for a string like this: number*word/number*word But it only accept integer number... Does anybody knows how to change it to accept decimal numbers like 0.1??? Thanks, Wagner Garcia Campagner -

RE: Regular Expression

Hi Wagner, This should do the trick... $List =~ /^(?:([\d|\.]+)\*)?(\w+)\/(?:([\d|\.]+)\*)?(\w+)$/; Basically looks like you need a character class to accept a '.' as well. (However, this reg exp looks like it will let thru 100.0.0.1 is a number!) Joel -Original Message- From: Wagn

You need to read up on tainted variables, I think. perldoc perlsec The problem isn't that it is a CGI, pretty sure the problem is that it is setuid. http://danconia.org On Tue, 10 Dec 2002 07:20:16 -0800 (PST), Admin-Stress <[EMAIL PROTECTED]> wr

hi there - I did not try this, but it seems somewhat logical to me: $List =~ /^(?:(\d+(\.\d+)?)\*)?(\w+)\/(?:(\d+(\.\d+)?)\*)?(\w+)$/; > > Hello, > > > > I have this regular expression: > > > > $List =~ /^(?:(\d+)\*)?(\w+)\/(?:(\d+)\*)?(\w+)$/; > > > > It checks for a string like this: number

Re: Handling & =

Ah - I see the problem. I do a regex to replace all hex encoded characters BEFORE I split on &, thusly all %26's are replaced with & before I do the split. In terms of "why reinvent the wheel", I prefer not to use CGI.pm for simple form processing because it prevents me from doing something like

Really? How could I mix something like: print OUTPUTFILE $q->start_html('Application'); print OUTPUTFILE $q->center( $q->h2("My Company Name"), $q->p($q->strong("Application")), ); print OUTPUTFILE $q->p("Applicant's Name: ",$q->b($q->param("Name")); With something like print >> End_of_form? Is

Re: Handling & =

Well, I'm not all that familiar with the CGI.pm html generation functions, but if they simply generate HTML elements, there should be no reason you can't mix CGI.pm calls with your own html code. Something like: --- #!/usr/bin/perl use CGI; $q = new CGI; open(OUTPUTFILE, ">

Re: Handling & =

Nope, no luck. When I use something like: Print >> End_form; Name: $q->param("name") End_form My output looks like: Name: CGI=HASH(0x6590)->param("name") I think I tried this before and that's why I didn't use CGI.pm for variable processing. But hey... I'm open to correction! -John On 1

Re: Handling & =

>Print >> End_form; > >Name: $q->param("name") > >End_form That's because you can't execute perl code within this construct. It is essentially a double quoted string that just happens to span multiple lines. So, this doesn't work just like: print "Name $q->param('name')\n"; won't

Re: Handling & =

Ah yes... That makes sense. That's the solution I've used in other cases (for instance, resolving a CGI param to a path.) Unfortunately, it's not really practical to define a bunch of temporary variables for a form that may have hundreds (literally) of input fields. So, it looks like I'm back to

RE: can we use "system()" inside cgi ?

I did read it, but still dont understand. What does "tainted" means? I changed my cgi like this : #!/usr/bin/suidperl Then : chown root:root saveconfig.pl chmod 755 saveconfig.pl It's now 'partly working', it can changed the content of /etc/sysconfig/... by overwriting it's content

RE: can we use "system()" inside cgi ?

I don't know much about suidperl but if I were doing this, I probably wouldn't give root privileges to my CGI. If it doesn't need to happen instantaneously, I'd consider a two-step approach: (of course, it probably does need to run instantaneously since you're doing it as a CGI anyway...) Instead

RE: can we use "system()" inside cgi ?

Thanks Peter, I was thinking about it too ... changing the content of interface configuration (in /etc/sysconfic/...), then by using cron job, make the change happen. But still, how often I must run the cron? I was thinking like every 10 seconds? hmm not good idea because this process will not h

Re: How to get the biggest integers from an array?

Use the sort function: print sort @array; and for largest number first use: print reverse sort @array; For your particular problem: @sorted_array = reverse sort @array; foreach (@sorted_array) { # whatever you want to do with each number

Re: How to get the biggest integers from an array?

Oh, no, actually, I know quite about Perl. The problem is, I hardly have got any experience in programming, I read a lot. I've got 3 perl books and wasn't just thinking at the idea of using sort(). Thanks guys. -- Bob Erinkveld (Webmaster Insane Hosts) www.insane-hosts.net MSN: [EM

Re: Handling & =

You can use the CGI module this way: use CGI; my $q = new CGI; my $username = $q -> param('username'); my $password = $q -> param ('password'); ... #That's all with the CGI module. #Now you can use the normal HTML style of printing the page: print
