in reply to Conditional statements in CGI/Div

Hi slurch901,

Instead of putting the conditional inside the div(...) call, put it immediately afterwards (and start a separate print for the final $cgi->end_html()):

#!/usr/bin/perl -w use CGI; use CGI ":standard"; use CGI::Carp qw{ fatalsToBrowser }; $index = 0; $cgi = new CGI; print $cgi->header(), $cgi->start_html(), $cgi->div({-id=>pagewrap}); if($index==0) { print $cgi->p("Hello"), } print $cgi->end_html();

Notice that the code above has the very useful:

use CGI::Carp qw{ fatalsToBrowser };
This will cause many errors to display in the webpage itself, which is how I was able to see the error in my browser:
syntax error at /var/www/html/index.cgi line 10, near "if" Execution of /var/www/html/index.cgi aborted due to compilation errors +.
say  substr+lc crypt(qw $i3 SI$),4,5

    Thanks for the quick reply and the Carp statement, but if I do it the way you have done then $cgi->p("Hello") doesn't inherit the pagewrap div from the css as it's closing too early.

      Shouldn't you stop using CGI anyway? If you use something with MVC as CGI::Application or Catalyst you wouldn't have to bother with those details.

[GotToBTru]: i guess it's a placeholder, the code will only fill it in if there is nothing else to use
[GotToBTru]: but then .. if you have nothing to say, why not say nothing?
[MidLifeXis]: I have a user who has a lot of say on how some of our processes work that abhors significant blanks. Perhaps that is a part of it. A not-so-obvious "this space intentionally left blank" indicator.
[MidLifeXis]: On the back end, however, that doesn't mean that i have to use that value to indicate "undefined", no matter how much he thinks I should.
