how do I change line breaks in entered data into html code "< br >&qu

[Guest_imported]

I am a real beginner to this. I use perl for handling forms that post poetry and the like to my websight. What I would really like to do is turn the linke breaks (returns) on the entered data into html line breaks. Is this possible. As I said, I am a real beginner so please be as simple as possible.
Also, Is there a way of getting rid of spaces so that A A A entered on the form would turn into AAA ?

Hope you can help because I am stumped.

I had this problem when taking data from a mysql database. Try something like:
[tt]
while (<FILEHANDLE>) {
s/\n/<br>\n/g;
print;
}
[/tt]
this will replace all newlines with a html linebreak and a newline (the newline to make the html code prettier). You can modify it for your purposes.

For the spacing part use;

$variable =~ s// /g; # This will remove all spaces and replace with nothing (thus removing the space)

That should work for your second question. As for your second on, I am not sure. I think a return charachter in \r, but maybe people who are a bit more experienced will know for definate ;-)

$variable =~ s/\r/\<BR\>/g; # Prettry sure you need to escape the < and > signs ;-)

Hope that helps

That's great. Thanks both of you for the help. I'll try it out and see how I go. This will really help me.
Cheers to both of you.

Andy,
Actually I have figured out the problem with the spaces, but I can't seem to reverse the affect. Is there a way of doing this so that after the field has appeared once without spaces, it can later appear as it was typed, with the spaces?

If you could help me with this I would be grateful.

Thanks for the other piece of coding, it works an absolute treat. That is a much appreciated help. Cheers.

The code to replace spaces with nothing is backwards, it should be

$var =~ s/ //g;

And you don't need to escape the < or > in the other regex, but he's on the right track with the \r. To be even clearer, use \x0a (carriage return) or \x0d (linefeed), like this:

$var =~ s/\x0a|\x0d/<br>\n/g;

You could do the replacement on a copy of the variable, so:
[tt]
$copy_of_variable = $variable;
$copy_of_variable =~ s/\r/\<BR\>/g;
[/tt]
so now $variable has not changed.
