Question

inside of my Zend_Db_Table_Rowset Object i found this:

["_primary:protected"]

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

$rowsetObject->getPrimary()

Thanks for your help,
Alex

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.

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

$tableInstance->info('primary')

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')

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

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();
    }
}
