    How can I automatically generate username number, instead of leaving the choice to the user to take any username ?

    First user would be #1000, second #1001, 1003, etc...

    I am working on a project where each user have an ID number. I would like to use the default WordPress username field for this ID number.

    So, the user use is ID number + password to connect to the site.

    ** I will also install a ‘login with e-mail’ plugin so user will be easily abble to connect if he do not remember is number, perfect for brand new member **

    Here's my half baked ideas on this, I don't know how doable these are, such as causing an unforeseen errors, etc.

    In order to get a user ID, you must first insert a user, which means you must provide a login name. But it could always be "TBD" or something since it will be soon changed anyway. It would only be an issue if two processes try to add a user at the same time. Maybe you could pre-populate the field somehow with javascript, and possibly even hide it with CSS. But there must be a field, and it must have a value that is not in the DB.

    Then perhaps hook the action 'user_register', get the just inserted user data. Unset the user_pass field to indicate no password change. Place the user ID in the user login, nicename, display_name fields and call wp_update_user() to change the names in the DB.

    Completely untested, but I think worth a try, good luck.

    Actually, I would like the user login name to be the number. So the user connect with is 'id' ( which is for WordPress is regular Login ) .

    The only difference is than the user didn't chose it himself...

    Thanks for sharing your ideas

    Actually, my suggestion will do exactly that :)

    "Place the user ID in the user login (field)" User ID is the one assigned by mySQL during initial user insertion.

    I think you had in mind a different approach entirely. If it involves checking the login form field directly against the DB user_ID field, it would be difficult to implement cleanly.

    Hi guillaumes!

    Thanks for a brilliant script!
    I am facing a bit of a problem since if a user forgot his/her password, then a generated Number username automatically is added to the form.

    Is there a way to correct this?

    Many thanks!
