我有以下代码：

function create_account(){
    //You may need some data validation here
    $fname = ( isset($_POST[\'billing_first_name\']) ? $_POST[\'billing_first_name\'] : \'\' );
    $lname = ( isset($_POST[\'billing_last_name\']) ? $_POST[\'billing_last_name\'] : \'\' );

    $email = ( isset($_POST[\'email\']) ? $_POST[\'email\'] : \'\' );
    $pass = ( isset($_POST[\'password\']) ? $_POST[\'password\'] : \'\' );

    $phone = ( isset($_POST[\'billing_phone\']) ? $_POST[\'billing_phone\'] : \'\' );

    if ( !fname_exists( $fname ) && !lname_exist( $lname ) && !email_exists( $email ) && !pass_exist( $pass ) && !phone_exist( $phone ) ) {

        $user_id = wp_create_user( $fname, $lname, $email, $pass, $phone );

        if( !is_wp_error($user_id) ) {
           //user has been created
           $user = new WP_User( $user_id );
           $user->set_role( \'customer\' );
           //Redirect
           wp_set_auth_cookie( $user_id, false, is_ssl() );
           wp_redirect( \'/checkout\' );

           exit;
       } else {
           //echo \'Register failed\';
       }
    }

}
add_action(\'init\',\'create_account\');

除登录外，其他操作正常。我无法登录。密码错误，但在数据库或wp admin中更改密码后，登录即可正常工作。因此，我确信我的代码没有将密码存储在数据库中。

这是我的表格：

wp_create_user( $username, $password, $email );
