Remove the category/taxonomy description field?

Question

How can I remove the category/taxonomy description field? The one which shows up on the edit category/taxonomy page.

Answer 1

When no hook is available, you can always count on the old jQuery trickery...

add_action( 'admin_footer-edit-tags.php', 'wpse_56569_remove_cat_tag_description' );

function wpse_56569_remove_cat_tag_description(){
    global $current_screen;
    switch ( $current_screen->id ) 
    {
        case 'edit-category':
            // WE ARE AT /wp-admin/edit-tags.php?taxonomy=category
            // OR AT /wp-admin/edit-tags.php?action=edit&taxonomy=category&tag_ID=1&post_type=post
            break;
        case 'edit-post_tag':
            // WE ARE AT /wp-admin/edit-tags.php?taxonomy=post_tag
            // OR AT /wp-admin/edit-tags.php?action=edit&taxonomy=post_tag&tag_ID=3&post_type=post
            break;
    }
    ?>
    <script type="text/javascript">
    jQuery(document).ready( function($) {
        $('#tag-description').parent().remove();
    });
    </script>
    <?php
}

Answer 2

Use CSS, I was implementing the JS solution and I didn't like the delay, then I've remembered about this.

body.taxonomy-name .term-description-wrap {
  display:none;
}

Answer 3

AFAIK, you can add new fields but you cannot remove the old ones! They are directly printed, and not stored in a variable to which a filter can be applied. Ref: wp-admin/edit-tags.php, line no. 380.

Answer 4

The most efficient way of 'removing' it is to apply CSS to the admin area, by using the 'admin_head' action hook.

add_action('admin_head', 'my_admin_area_custom_css');

function my_admin_area_custom_css() {
    echo '<style>
        body.taxonomy-name .term-description-wrap {
            display:none;
        }
  </style>';
}

NB: Update the body.taxonomy-name to the taxonomy name you wish to hide the description field for.

There is not a hook to remove the markup from the document, hence hiding it with CSS.

Answer 5

I used the jQuery below to achieve this as well.

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

Answer 6

On the Edit Category/Taxonomy page, .parent() doesn't remove the form field's label. Here's the jQuery for complete removal on both pages:

$('#tag-description').closest('.form-field').remove();
$('#description').closest('.form-field').remove();

Answer 7

I guess this would be a good answer

add_filter('manage_edit-product_cat_columns', function ( $columns ) {
    if( isset( $columns['description'] ) )
        unset( $columns['description'] );   
    return $columns;
} );
