Thanks for the report, @ernilambar !

This definitely seems like a bug. I was able to reproduce with the steps you provided.

With this being said, I'm not sure it ever worked in the first place 🙃

Feel free to submit a pull request, if you'd like. Here is some guidance on our pull request best practices.

I dug deeper into adding/updating menu item stuffs. Yes, this has not worked till now because when there is new position value, menu_order value of all menu items in that menu should shuffled which we have not done.

We have done only for add:

if ( ( 'add' === $method ) && $menu_item_args['menu-item-position'] ) {
  $this->reorder_menu_items( $menu->term_id, $menu_item_args['menu-item-position'], +1, $result );
}

This reorder_menu_items() only works for an item and makes sense in adding. We cannot reuse this method. We need to introduce separate method for reshuffling menu order for update.

Additional information about this issue.

Slightly simpler reproduction steps

First, I was able to reproduce this issue with a slightly simpler command set by leaving off the --link flag during the update call:

Create the menu and items:

wp menu create "Sample Menu"
wp menu item add-custom sample-menu Alpha https://alpha.com/
wp menu item add-custom sample-menu Beta https://beta.com/

Try to move Beta item to position 1:

wp menu item update 5 --position=1

Show that Beta did not move:

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
4,custom,Alpha,https://alpha.com,1
5,custom,Beta,https://beta.com,2

New behavior discovered by moving first menu element

Oddly enough, even though Beta cannot be moved to position 1, Alpha can be moved to position 2

wp menu item update 4 --position=2

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
5,custom,Beta,https://beta.com,1
4,custom,Alpha,https://alpha.com,2

With Alpha in position 2, both Alpha and Beta can be moved freely:

Move Beta to position 2:

wp menu item update 5 --position=2  

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
4,custom,Alpha,https://alpha.com,1
5,custom,Beta,https://beta.com,2

Move Beta back to position 1

wp menu item update 5 --position=1

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
5,custom,Beta,https://beta.com,1
4,custom,Alpha,https://alpha.com,2

However, once Alpha is moved back to position 1 Beta is again prevented from changing position

Move Alpha back to position 1:

wp menu item update 4 --position=1

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
4,custom,Alpha,https://alpha.com,1
5,custom,Beta,https://beta.com,2

wp menu item update 5 --position=1

Show that Beta did not move:

wp menu item list sample-menu --format=csv
db_id,type,title,link,position
4,custom,Alpha,https://alpha.com,1
5,custom,Beta,https://beta.com,2

---

Edit: I see what's happening. The item update command is always updating the menu_order column for the posts in the wp_posts table. When Alpha and Beta share the same order position, they still display in alphabetical order.

@ernilambar, is this still not fixed? I can see that some work was done in #502 but apparently it's not fully working.

[ernilambar]

@petruchek Yah, not fixed. That approach did not work without breaking other things. Now in block era, this issue does not get enough traction as it is not much used. 😊
