Passing String's in HTML forms

Hey,
I have a form where a user can enter any comments about the website. I then have a preview page that previews the comments.

But when I enter a " . Into the comments section anything after that is printed out.

I know why.
say i have
<input type='hidden' value='<?php echo $comments' ?>

PHP echos the comments so the " gets put in there and the input type ends.

Does anyone know how I can overcome this?
Or is there any way to pass the $HTTP_POST_VARS array to the save page?????

Or any better methods to do the same thing would be appreciated.

checkout addslashes, and stripslashes in the php manual

addslashes() & stripslashes() should help

yeah there is on problem with that stuff,

but php echo's the message and because there is a " in there. The HTML code interprets that as the end of the <input> 's value.

Is there anyway I can get around that?
Are there escape characters in HTML?

You could also try:
<input type='hidden' value='<?php echo htmlspecialchars($comments); ?>'>
