text editor inside a form textarea ?

[Hal Halloway]

I want a text editor inside a form's textarea,

So I would see html markup and html entities - just like a text editor.
I also would want to be able to edit it all just like a text editor -
this is done in PHPMyadmin for example...is there an easy way to do this?

In a way i'm asking the browser to suspend rendering markup.

euh...
echo "<textarea name='field1'>$yourfield</textarea>";

??

I've see such things but they're written in Javascript and only work on
IE:

I think this is what you are after:
<textarea><?php echo htmlentities($the_code_string) ?></textarea>

That way, all HTML code will not be rendered (because "<" is replaced
with "&lt;" etc.), but it will show up as if you were viewing the source
of the document...

If that's not what you are after, take a look at this:

Actually you don't need to use htmlentities.
Because it is already in <textarea></textarea> it works fine!
So:
<textarea><?php echo $the_code_string ?></textarea>
OR
<?php echo htmlentities($the_code_string) ?>
But no need of:
<textarea><?php echo htmlentities($the_code_string) ?></textarea>

So what will happen is $the_code_string just happens to have the string
"</textarea>" in it?

Not escaping is the first step towards XSS.

Sorry if this posts twice, but it didn't show up through my reader, so
I had to use GG...
Unless you have another textarea in it....

<?php
$string='<b>This</b> has a textarea: <textarea></textarea> This is bad
for the page.';
?>
<textarea><?php echo $string ?></textarea>

Also, I think that if you don't use htmlentities it won't validate via
W3C.

Never omit htmlentities when outputting untrusted content to your pages.
It doesn't matter where you place it, it can be harmful even inside an
HTML comment.

yes, you're perfectly right!!
I was thinking only about "format" tags like <h1>,<font> etc etc.

but you're right, it's always better to use htmlentities!!
I apologize for my wrong answer :(

This works OK and is XSS-safe:

<textarea><?php echo htmlspecialchars($string); ?></textarea>

Or, if you want, that even if due to impossibility to represent some
characters in document charset browser had encoded them into &#nnn;
form they anyway will be shown as they were typed:

<textarea><?php echo preg_replace('/&amp;(#\d{1,5}|[a-z]{1,10});/i',
'&\1;', htmlspecialchars($string)); ?></textarea>

Both examples works fine in IE and Mozilla Firefox. Second example will
make some problems with Opera versions before 7.5 and there it'll be
hard to use &#-encodings for characters outside the document's charset.
