text area minus formatting

By R

Hi, I would like to have an input text box in a plugin I am making. In the text box I want to input css code. The problem is that when I have TinyMCE activated the css code get saved with tags such as <p> and <br>. I am using the following code right now,

echo "<br><br><p>[1] Input css code</p> ";             

    if(empty($vars['entity']->csscode)){
    $vars['entity']->csscode = "";
    }
                                     
echo elgg_view('input/longtext', array('name' => 'params[csscode]',
                                      'value' => $vars['entity']->csscode,
                                    'class' => 'easytheme', ) );

Can I use this same code bu disable the text formatting in the elgg_view function just for this text input box?

Thanks.
