use of a Perl variable in added HTML code show only the variable name

[nicmic]

I have added a textarea field to the sidebar with a output filter module. As long as good.
Sadly i'm more experienced with c++ and js and so its a fight with Perl as beginner.

Code: Select all

my $txt = "test";
 
#add new textarea
my $sbTextArea= q~
 <textarea id="info" data-id = $txt ></textarea>
~;

${$Param{Data}} =~ s{(<...>)}{$1$sbTextArea};

At the moment i have no idea how i can use the Perl variables in the HTML code.
The data-id will be showed as "$txt" and not with value test?

if you do not want $txt to be shown as '$txt' but as the content of the variable, don't use the q-notation. Of course, there's more than one way to do it, just two samples:

Code: Select all

 my $sbTextArea= '<textarea id="info" data-id =" '.$txt.'" ></textarea>'; 

..or..

Code: Select all

 my $sbTextArea= "<textarea id=\"info\" data-id = \"$txt\"></textarea>"; 

... or others.

PS: I added missing quotation marks in data-ids value assignment - this has nothing to do with your Perl-issue

Ok, used instead the q notation the single quotes + "'.txt.'" and this works. Thank you.
