我有一个 ZF2 项目,它有 2 个模型 PostTable/TopTable,它扩展了 AbstractTableGateway。
我想对这些表的结果进行分页,所以我在这两个表中都有一个分页功能。
这就是 PostTable 模型的样子:
...
class PosTable extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'pos';
$this->adapter = $adapter;
}
...
public function getPosPaginator($tid) {
$sql = $this->getSql();
$select = $sql->select();
$select->where('tid = '.$tid)->where('deleted = 0')->order('crdate ASC');
$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $sql);
$paginator = new \Zend\Paginator\Paginator($adapter);
return $paginator;
}
...
效果很好。但在我的 TopTable 中,它看起来像这样:
...
class TopTable extends AbstractTableGateway {
public function __construct($adapter) {
$this->table = 'top';
$this->adapter = $adapter;
}
public function getTopPaginator($fid) {
$sql = $this->getSql();
$select = $sql->select();
$select->where('fid = '.$fid)->where('deleted = 0');
$adapter = new \Zend\Paginator\Adapter\DbSelect($select, $sql);
$paginator = new \Zend\Paginator\Paginator($adapter);
return $paginator;
}
...
对于 PostTable,我的控制器看起来像这样:
...
public function posAction(){
...
$pos = $this->getPosTable()->getPosPaginator($tid);
$pos->setCurrentPageNumber($pageid)->setItemCountPerPage(19);
... return $pos etc...
相同的控制器 topAction:
...
public function topAction(){
...
$top = $this->getTopTable()->getTopPaginator($fid);
$top->setCurrentPageNumber($pageid)->setItemCountPerPage(20);
...return $top etc..
在那个控制器中,我还获得了这些功能:
public function getTopTable(){
return $this->getServiceLocator()->get('Application\Model\TopTable');
}
public function getPosTable(){
return $this->getServiceLocator()->get('Application\Model\PosTable');
}
PostTable 分页工作完美,但 TopTable 分页不起作用。我收到此错误:
Fatal error: Call to a member function select() on a non-object in ....
看起来像
$sql = $this->getSql();
不返回对象。我怎么解决这个问题?一个有效,一个无效,没有明显的原因。
我的 module.php 看起来像这样:
namespace Application;
class Module
{
public function getAutoloaderConfig()
{
return array('Zend\Loader\StandardAutoloader' =>
array('namespaces' =>
array(__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,),
),
);
}
public function getConfig()
{
return include __DIR__ . '/config/module.config.php';
}
public function getServiceConfig()
{
return array(
'factories' => array(
'Application\Model\TopTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\TopTable($dbAdapter);
return $table;
},
'Application\Model\ForTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\ForTable($dbAdapter);
return $table;
},
'Application\Model\PosTable' => function($sm) {
$dbAdapter = $sm->get('Zend\Db\Adapter\Adapter');
$table = new \Application\Model\PosTable($dbAdapter);
return $table;
},
),
);
}
}
