根据第一个角色更改第二个角色

大家好，我在这里找到了这个代码片段：

add_action( \'set_user_role\', function( $user_id, $role, $old_roles ) 
{
   // Your code ...

}, 10, 3 );

资料来源：Execute a function when admin changes the user role

并希望对其进行修改，以便可以通过以下方式设置用户角色：

1个用户具有角色“level0”和“customer”->角色“level1”和“vendor”

2用户具有角色“level1”和“vendor”->角色“level0”和“customer”

如果管理员将角色“level0”更改为“level1”，则代码应将第二个角色从“客户”更新为“供应商”，反之亦然。

我尝试了以下代码，但不起作用：

add_action( \'set_user_role\', \'rb_update_user_role\',10,3);
function rb_update_user_role(){

   $user_id = get_current_user_id();
   $user = new WP_User ($user_id);

   if (current_user_is(\'s2member_level0\') && current_user_is(\'vendor\')){

      $user->remove_role(\'vendor\');
      $user->add_role(\'customer\');
   }
   if(current_user_is(\'s2member_level1\') && current_user_is (\'customer\')){

      $user->remove_role(\'customer\');
      $user->add_role(\'vendor\');
   }
}

有没有任何建议或代码片段可以帮助我解决这个问题？还是我需要另一种方法？

编辑：

当用户被激活时，我添加了第二个这样的角色

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\');
   }

}

//Update Roles automatically when Membership Level changes function rb_update_user_role( $user_id) { $user = new WP_User( $user_id ); $user_meta=get_userdata($user_id); $all_role = $user_meta->roles; foreach ($all_role as $role_value){ if ($role_value === \'vendor\'){ $user->remove_role( \'vendor\' ); } if ($role_value === \'customer\'){ $user->remove_role( \'customer\' ); } if ($role_value === \'s2member_level1\'){ $user->remove_role( \'s2member_level1\' ); $role = \'s2member_level1\'; } if ($role_value === \'subscriber\'){ $user->remove_role( \'subscriber\' ); $role = \'subscriber\'; } } if ( $role === \'subscriber\' ) { unset($new_role); $new_role = array($role => 0 ,\'customer\' => 1) ; update_user_meta($user_id, \'wp_capabilities\', $new_role); } if ($role === \'s2member_level1\'){ unset($new_role); $new_role = array($role => 0,\'vendor\' => 1) ; update_user_meta($user_id, \'wp_capabilities\', $new_role); } } add_action( \'profile_update\', \'rb_update_user_role\', 99, 1 );

rb_update_user_role( $user_id, $role ) { // error_log( "Setting user $user_id to role $role" ); if ( $role !== \'s2member_level0\' && $role !== \'s2member_level1\' ) return; $user = new WP_User( $user_id ); if ( $role === \'s2member_level0\' ) { $user->remove_role( \'vendor\' ); $user->add_role( \'customer\' ); } else { $user->remove_role( \'customer\' ); $user->add_role( \'vendor\' ); } } add_action( \'set_user_role\', \'rb_update_user_role\', 10, 2 );
