textarea problem

P

Paul Lalli

I have a textarea in a script that displays and when the user submits
something it sends the output to the browser from the textarea, why is is
that when I press the return key within the textarea and type more text
below my carriage return does that text below the carriage not display? I
don't have any special parse code, I'm using cgi.pm.

After everything, you STILL refuse to follow the posting guidelines? What
part of "post a short but complete program that demonstrates your problem"
is difficult for you to understand?

It amazes me you still expect people to help you.

When you're entering the text? Or when you are later displaying the
text?

If the former, look to the HTML specification -- you may need to specify
more rows to your textarea. If the latter, you would need to make sure
that your processing of the data properly handles cases where there are
embedded newlines.

ok, I'll demonstrate, I thought this would be an easy one.


use strict;
use CGI qw :)standard);

mainprint ();
output();

sub mainprint
{
print header;
print <<END;
<html><body><form action="thisscript.pl" method="post"><textarea
name="test"></textarea></form></body></html>
END
print "\n";
}

sub output
{
if (param ('test'))
{
print (param ('test'));
}
}

Clearly, it's untested. If you had tested it, first you would have found
there's no submit button. Once you added that in, you'd have found that
IT WORKS FINE. All the text is displayed no problem. So one more time,
POST A COMPLETE SHORT PROGRAM DEMONSTRATING YOUR PROBLEM. Why do you have
so much reluctance to do that? Seriously. I really do not understand.
The script prints everything on the first line of the textarea before my new
line with the return key.... anyone know why?

Really? Where? Show me. Give me the URL and the ability to view the
source code.

this is totally off-topic, but for anyone who wants to post and read on a
free server, I found a good one, it's

right, and how would I do this, I've been racking my brains for a while on
this one... is it % followed by something like %20 is a space that I have to
replace with a newline.

I'm posting this so users won't get confused with textareas and cgi.

it was a problem with the script, not a problem with the textarea or the
parse code. I was basically reading the lines from a textarea into a text
file, and before the textarea I'd put a number and then a special string (to
split) and then an indentifier, post or comment, and then the textarea
contents. The problem was whenver the textarea input included a newline it
would screw up the way the file was parsed and printed later on, I finally
figured out that all I had to do was remove the newlines and replace them
with "<br>" and then remove the carriage returns and replace them with
nothing so it would be a "<br>" everytime someone inputed a newline into the
text area. The code is as follows.
$posttext = param ('posttext');
$posttext =~ s/\r/<br>/m;
$posttext =~ s/\n//m;
#and then I printed param ('posttext') - and it worked

I'm stupid.
