It may just be that I'm new to CGI so I'm having to take what I am learning and throw it out the window? I am not sure TT is what you want. If you want to run perl code from within a html tags that's not possible as far as I know. You could use Greg's suggestion of http://perl.apache.org/embperl/ or use AJAX to call your perl cgi scripts. But if you insist that you want to put you code in the page then you really want ?php Dp. I'm not trying to put perl code into the page, they way I have it now is I have the page generated by my CGI script inside another page that is using my CSS. I've tried to have my CGI script directly handle my CSS but it didn't work due to its limited support for CSS. So now I'm trying to find a better way to make my CGI script look like the rest of my site, I'm guessing this is what Template Toolkit if I can figure out how to do it, or if my solution is the best. if you decide to go with a template system , a good simple one I use quite a lot is the module HTML::Template . this allows you to have separate html template pages with place holder tags that your CGI script would process and then output to the calling browser. You could then just take your regular html page with your css stuff applied and replace those bits that have to have a calculation or other function with a template var. you then can maintain the look of your static pages with your dynamically generated pages . Greg Correct me if I am wrong but these template systems seem to only handle output from the CGI script, which would be nice if my scripts only handled output but they also need user input. -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAklHALEACgkQRMKiLy/EUZTeSwCfU+LlVieDGdHCRKUL+ctSGDF7 0K4AoKwU12fat1aYvympNaDk+T4PkmK0 =g0pf -END PGP SIGNATURE- -- To unsubscribe, e-mail: beginners-cgi-unsubscr...@perl.org For additional commands, e-mail: beginners-cgi-h...@perl.org http://learn.perl.org/

Browser sends input data to server 2. Server sends input data to program using CGI interface 3. Program does something (possibly with the data) and generates output data 4. Program passes output data to template 5. Template places output data into some HTML (or whatever) 6. Template passes HTML combined with output data to the program 7. Program outputs HTML combined with output data to server using the CGI interface 8. Server sends output HTML back to the browser Templates are used because it is easier to edit HTML in a template then it is to edit Perl that generates HTML. -- David Dorward -- To unsubscribe, e-mail: beginners-cgi-unsubscr...@perl.org For additional commands, e-mail: beginners-cgi-h...@perl.org http://learn.perl.org/

Most people find that templates are simpler for most purposes (since they can then just write HTML and say Insert data here rather then describing every element in Perl). - From what I see in the tutorial, http://template-toolkit.org/docs/tutorial/Web.html#section_Dynamic_Content_Generation_Via_CGI_Script, the Templete Toolkit only outputs information from the script, but I need it to handle input as well You use Perl to handle the input. TT is just for making it easy to write the output. I've just remembered this simpler example: http://github.com/dorward/simple-ajax-demo/tree/master The script itself is at http://github.com/dorward/simple-ajax-demo/tree/master/webroot/demo.pl Line 32 gets user input, in exactly the same way that CGI.pm would do (I'm using CGI::Fast for this, which is similar). Line 33 uses that input to change what request gets sent to the database on ... Line 42 (which) gets a list of messages from the database (much like a guestbook would). Line 49 wraps it up in a hash. Ignore lines 51 to 56, these output JSON instead of HTML. Line 59 gives that hash to a template. http://github.com/dorward/simple-ajax-demo/tree/master/templates/html.tt is that template. Lines 15 to 21 of that template loop over the data and output HTML. The rest of the template is plain, simple HTML which is easy to edit (and line 6 pulls a stylesheet in). -- David Dorward http://dorward.me.uk/ -- To unsubscribe, e-mail: beginners-cgi-unsubscr...@perl.org For additional commands, e-mail: beginners-cgi-h...@perl.org http://learn.perl.org/

I have tried that and when I tried to call up a div object, in my css

Did you perhaps use 'div class='leftcolumn' ?
That will not work with your stylesheet.
div id='leftcolumn' *will* work
Here is a little cgi program that uses CGI.pm and your style sheet to print
a some stuff in a blue column on the left side of the screen:
#!/usr/bin/perl
use warnings;
use strict;
use CGI;
my $q = CGI-new();
print $q-header(), $q-start_html(-title=list msg test,
-style={'src'='/css/se.css'}),
'div id=leftcolumn';
for (my $i = 1; $i 26; $i++) {
print $q-br(blue column line $i);
}
print '/div', $q-end_html();
I have tried div id but they way I tried it was different, this is how I
tried it
print div id=leftcolumn;
print Some information;
print /div;
I guess that I was doing something wrong because it is working now thank
you for the help
- From what I see in the tutorial,
http://template-toolkit.org/docs/tutorial/Web.html#section_Dynamic_Content_Generation_Via_CGI_Script
,
the Templete Toolkit only outputs information from the script, but I
need it to handle input as well, my script I am working on is a
guestbook so it needs to get the name of the guest and a message then
output it, as well as save it to a log for later use by the script.
Everything works but the plain white background is ugly and doesn't
match the rest of my site which is why I started this thread.
You seem to be under the mistaken impression that you cannot get input using
CGI.pm or Template::Toolkit.
That is incorrect, either of those tools allow you to generate forms that
can be used to get input from the user.
If you look at perldoc CGI the very first screen contains an example of how
to generate a form.
I know how to generate forms with CGI which is where I have been putting
my forms, but I didn't think that Template::toolkit could generate a
form and pass the information off to the script for processing.
Hope this helps,
Mike
