以下是我想要实现的目标：

s2\\u member\\u level0具有第二个角色“customer”-当通过s2member提供的快捷码升级帐户时，帐户应升级到s2member\\u level1，并将其第二个角色更改为“vendor”

和

s2\\u member\\u level1具有第二个角色“供应商”-当通过s2member提供的快捷码降级帐户时，帐户应将自身降级为s2member\\u level0，并将其第二个角色更改回“客户”

我正在设置不同帐户的角色，同时在我的子主题中使用此功能激活这些帐户：

add_action( \'bp_core_activated_user\', \'add_secondary_role_new\', 10, 1 );

function add_secondary_role_new( $user_id ) {
  global $members_template;
  $user = get_user_by(\'id\', $user_id);
    if (user_can($members_template->member->id,\'s2member_level1\')){
      $user->add_role(\'vendor\');
    }
    else{
      $user->add_role(\'customer\');
    }
}

我想用这些功能更改用户角色，这些功能基本上更新数据库中的用户数据：

function change_role_while_upgrade_account(){
  global $members_template;
  $user = get_user_by(\'id\', $user_id);
  $user = wp_update_user(array(\'ID\'=>$user,\'role\'=>\'vendor\'));
}

function change_role_while_downgrade_account(){
  global $members_template;
  $user = get_user_by(\'id\', $user_id);
  $user = wp_update_user(array(\'ID\'=>$user,\'role\'=>\'vendor\'));
}

所以问题是：我如何将这个函数（如果它们正在工作）用于s2成员生成的短代码？有没有人能帮我找到线索？

我的升级短代码：

[s2Member-PayPal-Button modify="1" level="1" ccaps="" desc="Upgrading Account to Premium" ps="paypal" lc="" cc="EUR" dg="0" ns="1" custom="www.netz-mitteldeutschland.de" ta="0" tp="0" tt="Y" ra="2799.00" rp="1" rt="Y" rr="1" rrt="" rra="1" image="default" output="button" /]

取消订阅的短代码：

[s2Member-PayPal-Button cancel="1" image="default" output="anchor" /]
