Mirror text from textarea into input box?

[phpnoob11]

Hello, im trying to get a textarea text to be mirrored on to a input box so the input box can save to database

 

<div class="sf-box text">
<label for="fld<?php echo ++$forum_page['fld_count'] ?>"><span><?php echo $lang_profile['Yahoo'] ?></span></label><br />
<span class="fld-input"><input id="fld<?php echo $forum_page['fld_count'] ?>" type="text" name="form[yahoo]" value="<?php echo(isset($form['yahoo']) ? forum_htmlencode($form['yahoo']) : forum_htmlencode($user['yahoo'])) ?>" size="70" maxlength="400" /></span>
</div>

thats th input box

 

Does anyone know how i can create a textarea box that will then mirror onto a hidden input box?

Not sure I understand what you are talking about. The value is already available in the text area - why do you need to "mirror" it (whatever that means) into a text box? Why can't you use the value from the text area?
