First of all, you shouldn't be using addslashes(). If you're writing to
a MySQL database, you should be using mysql_real_esca pe_string() instead.

As for the new lines - how is your code to know which are inserted by
the textarea and which are inserted by the user? Better to use send the
data correctly in the first place. See the WRAP attribute of a textarea .

Surely that should have been: "Better to use send the data correctly
in the first place. See the WRAP attribute of a textarea. But this
has nothing to do with php.

I'm learning a little about using forms in php to enter data, and have a
couple of questions re textarea.
At the moment I just use "addslashes () to process the value from textarea
so that punctuation is escaped, and write this into a table.
When the text wraps in the text box I get a new line in the value
returned, as well as new lines that I enter manually.

IIRD, "wrap" is not an attribute of textarea in any version of html or xhtml
I've used - it's a proprietary attribute of Netscape/IE. You're just asking
for cross-browser trouble if you use it. Check out the white-space attribute
of CSS.

If this is for web display and you need to generate a hard new line in html,
use <br />.

Thanks for the pointer. I wasn't worried about sql injection as these are
not on public pages, but worth knowing for the future.
The wrap attribute does what I need.
Thanks

You need to be worried about SQL injection, especially on internal
sites. More damage can be done by disgruntled employees than hackers.

What I want is textarea not to insert line breaks just because the user
enters a line that is longer than the number of columns. Wrap can do this in
IE/FF/Opera etc.
I cannot see how css can alter the behaviour of textarea as to whether it
inserts hard line breaks when a line wraps in the textarea box ?

Cannot see or haven't tried to?
I put
css white-space
into Gogle and pressed "I'm Feeling Lucky" and got a pretty good
explanation.

That doesn't stop the insertion of a line break when the text wraps. It
just controls whether the line wraps or not.

No, "wrap" is not an HTML attribute, but it is supported every recent
browser I've tried.

And for Tony, <br /is not a valid html break.

Yes, as has been metioned in recent threads, w3schools is good for an
introduction, but it doesn't always tell one the whole truth.
I do think that this particular w3.org section is one of their clearer
ones.

"<br/>" is valid in HTML. It just doesn't mean what people think it means.
It is equivalent to "<br>>" because of SGML shorttag rules.

w3.org and w3schools.com are entirely different websites. Do not get them
mixed up.

w3.org is the World Wide Web Consortium (W3C), an organisation set up by
Sir Tim Berners-Lee to steer the development of the web, supported by many
academic organisations, browser makers and content producers. They have
been responsible for all HTML specifications since version 3.2, and for
CSS, the DOM, XML, SVG, RDF, SOAP and various other web-related
technologies. This responsibility for them has been informally delegated
to them by the IETF.

w3schools.com is a tutorial website owned by a small Norwegian company
called Refsnes Data. Although their tutorials are generally fairly good,
the company is in no way affiliated with the W3C, and their tutorials are
no more "official" than any turoial you or I could put together. Most of
their tutorials are aimed at helping your learn W3C standards, and other
web-related technologies.
