[OT] How to preserve carriage returns in text area inputs?
I'm finding that my form data is not preserving carriage returns. When a user
has a text area to fill in that is multiple lines, carriage returns are not staying
in the $fdat{fieldname}.
If I take the data that is input on the form and on the next page output it
again, it shows up as spaces where I pressed Enter.
Why is this and can I make it keep these carriage returns?
TIA!
Scott

alternatively, just do: <pre>[+ $text +]</pre>
or even (if your browser is new enough):
<div style="white-space:pre">[+ $text +]</div>

The cr's are preseverd, but if you output a newline in html text, nothing
happens...
So what you really want is to subsitute newlines with <BR> before outputing.
To get a 100% correct escaping of the rest of text, do something like (if
you simply subsitute \n with <br> you have to set $escmode to zero before
outputing, in which case the rest of the text is not correctly escaped)
[- @lines = split /\n/, $fdat{text} -]
[$foreach $l (@lines)$]
[+ $l +]<br>
[$endforeach$]

Whoops. Forgot to mention that
http://www.home.zonnet.nl/robschluter/htmltaglist/index_old.html
gives a comprehensive listing of all tags and attributes.

The "wrap" attribute of the textarea tag is the one you want.
set it to "hard" to wrap at the display boundaries and at user entered
return characters.
set it to "soft" to wrap only at user entered return characters
(the display will still wrap but the lines will be sent as long
strings)
The default is off. I usually set it to "hard" because I'm usually
saving the output somewhere and so having a maximum column width is
useful.
