I've got a wordpress site, and that i produce a box at admin area dashboard that have a text area, and today i would like my textarea implement ckeditor, does anybody understands how to get it done?

here's my code snippet at styles functions.php

    function tresquint_news_dashboard_widget(){
     if ( $_POST['tresquint_submit_news'] ){
      $options = $_POST['tresquint_news'];
      $options['time'] = time();
      update_option('tresquint_news', $options );
      echo '<div class="updated fade"><p>Updated news.</p></div>';
     $options = get_option("tresquint_news");
     ?><form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<p><?php _e("Enter a short news"); ?></p>
<p><label for="tresquint_news_text"><?php _e('News'); ?></label><textarea id="tresquint_news_text" style="width: 100%; margin-top: 5px;" name="tresquint_news[text]"><?php echo $options['text']; ?></textarea></p>
<p class="submit"><input style="float: right;" type="submit" name="tresquint_submit_news" value="<?php _e('Publish'); ?>" /><div class='clear'></div></p></form><?php

if you notice on ,my code snippet above there is a text area, and i wish to change that text area into ckeditor UI.

Thanks ahead of time AnD

you should use the Plugin CKEditor For WordPress.

I understand wordpress merely a little, however, you will go using the ckeditor help, too:

<textarea id="editor1" name="editor1"><p>Initial value.</p></textarea>
<script type="text/javascript">
    CKEDITOR.replace( 'editor1' );
