问题描述

在我的 Zend_Db_Table_Rowset 对象中，我发现了这个:

["_primary:protected"]

...有没有人可以访问这个?...也许像

... does anybody if theres a way to access this? ... maybe something like

推荐答案

Zend_Db_Table_Rowset 没有属性 _primary.您所指的是您从中获得行集的 Zend_Db_Table 实例或行集内的 Zend_Db_Table_Row 实例.

Zend_Db_Table_Rowset has no property _primary. What you are refering to is either the Zend_Db_Table instance you got the Rowset from or a Zend_Db_Table_Row instance inside the Rowset.

要从 Zend_Db_Table 实例获取主键，您可以执行以下操作:

For getting the primary key from a Zend_Db_Table instance you can do:

$tableInstance->info('primary')

要从 Zend_Db_Table_Row 实例获取主键，您可以获取表实例并对其调用 info():

For getting the primary key from a Zend_Db_Table_Row instance you can get the table instance and call info() on it:

$rowInstance->getTable()->info('primary')

请注意，当行断开连接时，这将不起作用，因为这样 getTable() 将返回 null.

Note that this will not work when the row is disconnected, because then getTable() will return null.

或者，当使用自定义 Zend_Db_Table_Row 时，您可以添加一个代理到 _getPrimaryKey() 的方法:

Or, when using a custom Zend_Db_Table_Row you can add a method that proxies to _getPrimaryKey():

class My_Db_Table_Row extends Zend_Db_Table_Row
{
    public function getPrimaryKey()
    {
        return $this->_getPrimaryKey();
    }
}
