Category can be itself parent

[F J Kaiser]

Hi,

when i´m on admin-screen > posts > categories and edit an existing category. the drop-down offers, when selecting a parent-category, the category itself as it´s own parent.

---

if you try to take itself as it´s own parent-category, nothing happens and it falls back to "no-parent". so i decided the priority is "low". but maybe someone stumbles upon it and makes wp a little bit smarter :)

Confirmed.

pretty kool! :)

i tried a minor change and added 'echo' => 0, as an $arg and saved it as $var. then i echoed the $var. so you can easily get and use the function as a template-tag. in my case i try to use it to enchance my search with a drop-down to search only specific categories.

i added the function straight to my template and haven´t finished the search yet. but maybe it would be a nice addition.

what do you think?

em... sry. didn´t know that this is already avaible.

(In [11854]) Don't offer to make a category its own parent - that just wouldn't work. Fixes #10644 props scribu.
