Can't Add new category in WP > 3.5 ? This is a solution

Thanks a lot !

This ‘fix’ throws an error for me on line 38. Any ideas?

Hello,

The first message has a partial solution.

From the current version 1.0.2, here are the changes to be made :

Line 68
is:

<ul id="<?php echo $taxonomy; ?>checklist" class="list:<?php echo $taxonomy ?> categorychecklist form-no-clear">

should be:

<ul id="<?php echo $taxonomy; ?>checklist" data-wp-lists="list:<?php echo $taxonomy; ?>" class="<?php echo $taxonomy; ?>checklist form-no-clear">

Line 93
is:

<input type="button" id="<?php echo $taxonomy; ?>-add-submit" class="add:<?php echo $taxonomy ?>checklist:<?php echo $taxonomy ?>-add button category-add-sumbit" value="<?php echo esc_attr($tax->labels->add_new_item); ?>" tabindex="3" />

should be:

<input type="button" id="<?php echo $taxonomy; ?>-add-submit" data-wp-lists="add:<?php echo $taxonomy ?>checklist:<?php echo $taxonomy; ?>-add" class="button <?php echo $taxonomy; ?>-add-submit" value="<?php echo esc_attr($tax->labels->add_new_item); ?>" tabindex="3" />

Basically, there was a slight mixup between the class attribute and the data-wp-lists attribute.

The solution provided by rwatuny worked. It doesn’t properly add the category to the hierarchy so a page refresh is needed to show the newly added category at the correct level.
