Strip non-alphanumeric characters from generated usernames

  • Found the answer and figured I would share.

    Go to roughly line 354 or so and find this code block…

    $uarray = split( '@', $user['email'] );
$user['username'] = sanitize_user( $uarray[0] );

    Now change it to this…

    $uarray = split( '@', $user['email'] );
$uarray = preg_replace("/[^a-zA-Z0-9\s]/", "", $uarray);
$user['username'] = sanitize_user( $uarray[0] );

    That’s it.

    Okay, actually this may cause errors in some instances [related post]. Not sure why, but it works most of the time.

    Um, it appears I was running that regular expression on the wrong variable. How about this one, which adds an extra step to the WP sanitize_user() process (which leaves those pesky dots in place):

    $uarray = split( '@', $user['email'] );
$user['username'] = sanitize_user( $uarray[0] );
$user['username'] = preg_replace('/[^a-zA-Z0-9]/', '', $user['username']);
