对不起,我的英语不好我写了一篇关于这个话题的深入博客“”。但基本上,这是你必须做的: 基本上,您所要做的就是在表单中查询数据库中的数据。为此,您需要DB适配器在表单中可用,这是通过依赖项注入完成的。由于DB适配器是表单正常运行所必需的,因此我建议使用Setter注入 在
getServiceConfig()中执行以下操作:
return array('factories' => array(
'namespace-form-formname' => function($sm) {
$dbA = $sm->get('Zend\Db\Adapter\Adapter');
$form = new \Namespace\Form\Formname($dbA);
return $form;
}
));
这将把Zend\Db\Adapter\Adapter
注入到表单中,该表单应该已经通过其他配置有效。然后,您需要稍微修改一下表单代码:
public function __construct(\Zend\Db\Adapter\Adapter $dbA) {
parent::__construct('form-name');
// Do the DB-Query here. You got the DB-Adapter
// http://zf2.readthedocs.org/en/latest/modules/zend.db.adapter.html
$selectArray = array(
'key' => 'value',
'key' => 'value',
'key' => 'value',
); // obviously, this is just a fake-$selectArray demonstrating
// what the output of your Queries should be
// Add your Form Elements here
// use $selectArray as value_options of your desired select element
}
基本上就是这样。遗憾的是,我不能给你一个具体的例子,因为我从来没有使用过Zend\Db
,但我想这会让你开始
PS:在控制器中,按如下方式调用窗体:
$form = $this->getServiceLocator()->get('namespace-form-formname');
试试看:
//在控制器上添加代码
$arrPortalId=array();
$results=array('1'=>'portal 1','2'=>'portal 2','3'=>'portal 3',);//此部分将更改您的数据库值
foreach($结果为$key=>$val){
$arrPortalId[$key]=$va;
}
$dataParams['portalId']=$arrPortalId;
$form=newuserform($dataParams);
你不明白哪一部分?我如何在我的表格中包含另一个班级表格的选项。在本例中,我需要将选择填充的门户包含到表单用户中,但我不知道如何包含:/i我只是指出了如何将DB适配器包含到表单中。除了DB适配器,您还可以输入tablegateway或您喜欢的任何访问数据库的方式。我认为使用该网关更容易,因为查询执行的是类表。。我该怎么做?@andres请参考我最新的博客帖子,这篇文章更深入地涵盖了整个主题
$form = $this->getServiceLocator()->get('namespace-form-formname');
Try:
// add code on controller
$arrPortalId = array();
$results = array('1' => 'portal 1', '2' => 'portal 2', '3' => 'portal 3',); // this part change your database value
foreach ($results as $key => $val) {
$arrPortalId[$key] = $va;
}
$dataParams['portalId'] = $arrPortalId;
$form = new UserForm($dataParams);
