I still cannot see a good way to inject data into the wp_update_term database calls though. If you know of a good way, please let me know so that I can further improve the article.

Thanks!

You can go in and change the source file, but that generally isn’t a good solution because you will lose all changes whenever you update WordPress.

A better way is to add your new category interface using the add_meta_box command, and possibly remove the old category interface with the remove_meta_box command (??never used remove_meta_box before so don’t know for sure).

To create your new interface function, look at the source file -
wp-admin/edit-form-advanced.php

There should be a function in there called -
post_categories_meta_box

This is what wp calls to render its existing category box. Just copy that code and alter it in your own file to create the interface that you want. Then add it into the Edit post interface using add_meta_box.

It will only show in the full Edit Category screen though – not on the Add Category, Quick Edit, or other related screens.

Do you get any error messages? You may want to just do an echo in the your_input_box function and then visit the “Edit Category” source page to see if the echo comes through.

PS. As you get around well with WP admin hacks, is there a easy way to get around this: http://stackoverflow.com/questions/1552307/pseudo-custom-taxonomies-from-categories [reasons explained over stack overflow]

The I have checked the ‘Add New Post’ page where I couldn’t see any new inputs.
Am I doing things as supposed to?

<tr class="form-field">
	<th scope="row" valign="top">
        <label for="category_theme">
           <?php _e('Category Theme') ?>
        </label></th>
	<td>
<!-- Enter your own stuff here -->
	 </td>
</tr>

Can you share some of your code?
