dear monks,
i already had a lots of nice input thx to the chat, but the following piece of code is still not working.
the input is passed by an textearea from an user (browser), but the first regex eats all newlines, so there is nothing left for the second one.
i would want to have single linebreaks from the textearea to be turned out in <br> and double linebreaks in <\p><p>
use strict;
use CGI;
my $query = new CGI;
my $text = cleanup_txt( $query->param( 'text' ));
print ubb_txt( $text);
sub cleanup_txt {
my $str = $_[0];
return "" unless ( defined $str );
$str =~ s/[<>"'&|]//gs;
}
sub ubb_txt {
my $txt = shift;
return "" unless ( defined $txt);
my ($nl) = $txt =~ m{(\cM?\cJ)};
$txt =~ s{$nl$nl}{</p><p>}gs if (defined $nl);
$txt =~ s{$nl}{<br>}gs if (defined $nl);
}
thx for helping out it's my first *real* post maksl

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
