Re: How do you run a subroutine from inside HTML code?

Thanks for all who helped, but I got it running. I had to edit the code to this:

    foreach $index (keys %{$_[0]}){
        print "<TD WIDTH=\"$table_vars{$index}\">\n";
        &$index();
        print "</TD>\n";
    }

and I had to remove the & from $index so instead of $index = &login it is now $index = login

I'd first think to try the following, but that may be perl6 interpolation talking: `my $index = \&login; for (keys %{$_[0]}) { print qq[<TD WIDTH="$table_vars{$_}">\n$index->()\n</TD>\n]; }` [download] Generally, and definitely perl5, `"@{[foo()]}"` calls `&foo` as list context and interpolates the return value as with an array and `"${\foo()]}"` similarly, with scalar context and as a scalar. For your particular example, however, I'd just use printf. `for (keys %{$_[0]}) { printf qq[<TD WIDTH="$table_vars{$_}"\n%s</TD>\n], $index->(); }` [download] There is no need to escape quoting delimeters in Perl.
