我想問一些關於Zend Framework 2中TableGateway的幫助。基本上,我按照教程一步一步地做了小的修改,不知道我錯過了什麼。Zend Framework 2 TableGateway fetchAll方法返回空結果集,但表中包含數據
下面描述的問題與平臺無關,我能夠在Windows和Linux上重現它,但我現在只使用Windows。
我這個表我的MySQL服務器放在我的本地機器上:
CREATE TABLE `admmenu` (
`menu_id` int(11) NOT NULL,
`menu_name` varchar(255) NOT NULL,
`menu_desc` varchar(255) DEFAULT NULL,
`menu_category_id` int(11) DEFAULT NULL,
`is_active` int(11) NOT NULL DEFAULT '1',
PRIMARY KEY (`menu_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
INSERT INTO `admmenu`
VALUES (1,'add_outing',NULL,1,1),
(2,'list_outings',NULL,1,1),
(3,'add_income',NULL,2,1),
(4,'list_incomes',NULL,2,1),
(5,'add_organization',NULL,3,1),
(6,'add_category',NULL,3,1),
(7,'add_customer',NULL,3,1);
我有這個在我的AdmMenuTable PHP類:
namespace VSMoney\Model;
use Zend\Db\TableGateway\TableGateway;
class AdmMenuTable {
protected $tableGateway;
public function __construct(TableGateway $tableGateway) {
$this->tableGateway = $tableGateway;
}
public function fetchAll() {
$resultSet = $this->tableGateway->select();
return $resultSet;
}
}
在另一大類我所說的使用fetchall()方法來獲取數據集並想在foreach循環中對其進行操作。
我試圖轉儲我得到的數據集,但它是空的。如果我運行可以在mysql控制檯或mysql工作臺中的resultset對象中找到的sql查詢,那麼我得到了我想要的結果。
當我的代碼運行並且mysql日誌文件dos不包含任何問題時,沒有連接錯誤。

protected 'position' => int -1
protected 'generatedValue' => string '0' (length=1)
protected 'rowCount' => int 7
protected 'fieldCount' => int 5
protected 'position' => int 0
的serviceConfig看起來是這樣的:
'factories' => array(
'VSMoney\Model\AdmMenuTable' => function ($sm) {
$tableGateway = $sm->get('AdmMenuTableGateway');
$table = new AdmMenuTable($tableGateway);
return $table;
},
'AdmMenuTableGateway' => function ($sm) {
//$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$config = $sm->get('config');
$config = $config['db'];
$dbAdapter = new DbAdapter($config);
$resultSetPrototype = new ResultSet();
$resultSetPrototype->setArrayObjectPrototype(new AdmMenu());
return new TableGateway('admmenu', $dbAdapter, null, $resultSetPrototype);
},
AdmMenu類:
<?php
namespace VSMoney\Model;
class AdmMenu{
public $menu_id;
public $menu_name;
public $menu_desc;
public $menu_category;
public $is_active;
public function exchangeArray($data) {
$this->menu_id = (isset($data['menu_id'])) ? $data['menu_id'] : null;
$this->menu_name = (isset($data['manu_name'])) ? $data['menu_name'] : null;
$this->menu_desc = (isset($data['menu_desc'])) ? $data['menu_desc'] : null;
$this->menu_category = (isset($data['menu_category'])) ? $data['menu_category'] : null;
$this->is_active = (isset($data['is_active'])) ? $data['is_active'] : null;
}
}
?>
AdmMenu是什麼樣的?看起來結果集正在捕獲7條記錄,你怎樣調用fetchAll,你的問題似乎並沒有與事物的查詢結束。 – crowebird
Crowebird:這個班是附件,感謝您的幫助! – SayusiAndo
一切都很好,包括AdmMenu。你如何檢索ResultSet?你應該有這樣的$ rs = $ this-> getServiceLocator() - > get('VSMoney \ Model \ AdmMenuTable') - > fetchAll(); – crowebird
