perl CGI + dynamic table generation

kurrupt · 09-23-2006, 10:44 AM

I would like to create a randomly generated table by the user, the user will have the option to put x amount of cols and x mount of rows. once the user puts that in and submits it, i want the perl script to output that table with x cols and x rows

how would i make that possible?

Thanks!

wow, thanks for the lengthy description of your situation. with all that info im sure you will get plenty of accurate answers.

maybe try to list what you have so far, for starters do you have a server with perl enabled? do you even know perl? do you know how to make forms in html? etc, etc, etc

yes, i know perl more or less, and yes i know how to make tables in html, and yes i have a server with perl enabled and its already running some scripts:

iam just looking for a general snippit of code to work with? more or less

Eg:

Code:

HTML SIDE                                 |                    PERL SIDE OUTPUT TO BROWSER
---------                                 |                    ---------------------------
                                          | 
Please enter # of rows  [2]               |                ___  ___
Please enter # of cols  [2]               |                |   |   |
                                          |                |---|---|
Submit                                    |                |___|___|

well its going to be more than a "snippit" of code. if you know perl and html and also have the server setup, i dont see what the problem is..

maybe someone else will want to write the program for you, but i dont.

(not trying to be a smartass (well maybe a little), but have you even attempted it?)

Yes i have, iam sorry i didnt paste it earlier. when i run it, it bascially goes into a loop and makes a trillion cols with 1 row.

but here it is:

Code:

#!/usr/bin/perl

use warnings;
use CGI;

my $cgi = new CGI;

# |------------------------------------------|
# | Here iam bringing over the paramaters    |
# | from the user input. Eg: col=5 ,row=5    |
# |------------------------------------------|

my $col = $cgi->param('col');
my $row = $cgi->param('row');

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

print "<html>";
print "<body>";





# |------------------------------------------|
# | Here i want to make a dynamic table from |
# | the user input x col, and x row          |
# |------------------------------------------|

print "<table border=1>";

while($row!=0){

  print "<tr>";

          while($col!=0) {

              print "<td>";

              print "testdata";

              print "</td>";

              $col--;
          }

print "</tr>";
$row--;

}

print "</table>";
print "</body>";
print "</html>";

Do you know how make a formated webpage with your cgi script?
i am trying but keep getting server errors. I do not know any of the syntax, I am tryig to use other peoples code for a starters but I do not know where to begin.
I have a webpage that I want to calculate something with my script and create a formated webpage and print info on that page.

I am unable to even get the page to show up.

kurrupt,

(sorry i forgot about you until circuit_girl posted..)

one problem is that you need to use some sort of temp variable in the loops, when you decrement col for the first row, none of the other rows will have any cols.

i dont see why it would be printing out a ton of columns though.. try a print when you get the cgi data, and make sure the col and row are what you think they are..

circuit_girl, it would probably be appropriate to start a new thread for your question. it would definately get more attention that way, your question might get lost in this thread..

also when you start that other thread, post the errors you get when you try the page. if you dont see any obvious errors, check the error log for your server.
