I'm trying to capture comments from a textarea field to add to a
database but I cannot figure out how to deal with escaping the data.

<form action="review.rhtml" method="post">
<input type="hidden" name="date" value="<%=today%>">
<label for="comment">Your Comment:</label>
<br>
<textarea name="comment" cols="60" rows="5"></textarea>
<p><input type="submit" value="Submit Review"></p>
</form>
Is there something I can do to "<%=comment%>" to handle '' "" etc.

Many thanks any help is appreciated

You can escape characters in several different ways. The CGI class is
handy here, too. Example follows:

require 'cgi'
puts CGI.escape("black/white")

You can also unescape strings, and so forth. See the docs at
http://ruby-doc.org/core/classe...

It there is some string in particular you are looking for, you can
search for it with include?, and so on, using the String class, see docs
here:
http://www.ruby-doc.org/core/classes/S...

Did you have a more specific problem in mind?

Thanks for the tips. You gave me enough of a hint to to solve most of
the problem. There still seems to be a problem with characters like %
