自定义Joomla配置文件插件注册用户数据库表更新问题

Question

我有一个自定义扩展，它使用Joomla配置文件插件并对其进行扩展，以便在管理员面板和网站前端的注册区域中为用户配置文件提供其他字段。 这些字段设置为仅显示管理员，禁用，可选或需要。 当它们设置为仅限管理员时，它们不会在“编辑您的个人资料”表单中显示在网站的前端。 插件处理所有字段的UPDATE命令，管理员面板中没有任何问题，但是当用户在前端更新其配置文件触发UPDATE命令时，所有仅管理员字段都将被空值覆盖。 所有其他字段，无论是可选的还是必需的，都可以在表单中成功保存或维护。 我在下面包含了自定义配置文件插件的PHP代码。

@Elin我已经弄清楚了。 在Joomla论坛上建议使用两个$ fields数组，一个用于前端配置文件表单，另一个用于管理员用户管理器配置文件表单的所有字段。 我在下面列出了onUserAfterSave函数的PHP代码。 if（$ app-> isSite（）） if / else显示前端配置文件表单上的有限字段和管理员配置文件表单上的完整字段列表。

public function onUserAfterSave($data, $isNew, $result, $error)
{
    $app = JFactory::getApplication();
    $user = JFactory::getUser();
    $modified_by = $user->get('id');
    $userId = JArrayHelper::getValue($data, 'id', 0, 'int');

    $datenow = JFactory::getDate();
    $modified = $datenow->toSql();

    if($app->isSite())
    {
        $fields = array(
            'address1',
            'address2',
            'city',
            'province',
            'postalcode',
            'country',
            'businessphone',
            'homephone',
            'cellphone',
            'fax'
        );  
    }
    else
    {
        $fields = array(
            'firechief',
            'title',
            'organization',
            'organizationtype',
            'membertype',
            'afcaregion',
            'municipalcode',
            'membershipyear',
            'address1',
            'address2',
            'city',
            'province',

            'billpostalcode',
            'billcountry'
        );
    }

    if($isNew)
    {
        $db = JFactory::getDbo();
        $query = 'INSERT INTO #__kiduka_accounts VALUES(NULL, '.$userId.', "", '.$userId.', '.$userId;
        foreach($fields as $field)
        {
            $query .= ', "'.$data['kiduka'][$field].'"';
        }
        $query .= ')';
    }
    else
    {
        $db = JFactory::getDbo();
        $query = $db->getQuery(true);
        $query .= 'UPDATE #__kiduka_accounts SET ';
        $query .= 'modified = "'.$modified.'", ';

        for($i = 0; $i < count($fields); $i++)
        {
            $query .= $fields[$i] . ' = "'.$data['kiduka'][$fields[$i]].'"';
            if($i < count($fields) - 1)
            {
                $query .= ', ';
            }

        }
        $query .= ' WHERE user_id = "'.$userId.'"';
    }

    $db->setQuery($query);
    $db->execute();

    return true;
