Taxonomy Description WYSIWYG

On sites where we are using custom post type taxonomies, we often want to have archive page. The problem, is the description field for a taxonomy is a simple textarea field. WE WANT MORE! Here is the code needed to replace the “Description” textarea field with a WYSIWYG field.

add_action("{$taxonomy}_edit_form_fields", 'add_form_fields_example', 10, 2);

function add_form_fields_example($term, $taxonomy){
    ?>
    <tr valign="top">
        <th scope="row">Description</th>
        <td>
            <?php wp_editor(html_entity_decode($term->description), 'description', array('media_buttons' => false)); ?>
            <script>
                jQuery(window).ready(function(){
                    jQuery('label[for=description]').parent().parent().remove();
                });
            </script>
        </td>
    </tr>
    <?php
}

add_action("{$taxonomy}_edit_form_fields", 'add_form_fields_example', 10, 2);

function add_form_fields_example($term, $taxonomy){

<th scope="row">Description</th>

<td>

<?php wp_editor(html_entity_decode($term->description), 'description', array('media_buttons' => false)); ?>

jQuery(window).ready(function(){

jQuery('label[for=description]').parent().parent().remove();

});

</script>

</td>

</tr>

<?php

}
