Question

我的应用程序基于ZendSkeletonApplication，现在我想创建我的模型之间的关系，所以：

user            portal
id              id
firstName       name
lastName        url
........
portal_Id

我想在用户表单中用数据库值填充我的select-option

<?php
namespace Register\Form;

use Zend\Captcha\AdapterInterface as CaptchaAdapter;
use Zend\Form\Form;
use Zend\Form\Element;


class UserForm extends Form

    {
        parent::__construct('user');
        $this->setAttribute('method', 'post');
        $this->setAttribute('class', 'form-horizontal');

        $this->add(array(
                'name' => 'id',
                'attributes' => array(
                        'type'  => 'hidden',
                ),
        ));

        $this->add(array(
                'type' => 'Select',
                'name' => 'portal_id',

                        'value_options' => array(
                                '1' => 'portal 1',

        $this->add(array(

        $this->add(array(

                'name' => 'csrf',
                'options' => array(
                        'csrf_options' => array(
                                'timeout' => 600
                        )
                )
        ));

        $this->add( array(
                'type' => 'Captcha',
                'name' => 'captcha',
                'options' => array(
                        'label' => 'Please verify you are human.',

                ),
        ));
    }
}

在这部分我想要从数据库中选择填充

$this->add(array(
                'type' => 'Select',
                'name' => 'portal_id',
                'options' => array(
                        'label' => 'Portal',
                        'empty_option' => 'Seleccione un portal',
                        'value_options' => array(
                                '1' => 'portal 1',
                                '2' => 'portal 2',
                                '3' => 'portal 3',
                                //i want option from database with 
                        ),

                )
        ));

抱歉我的英文

Answer 1

我写了一篇关于这个主题的深入博客“Zend\Form\Element\Select and Database-Values”。基本上，这是你必须要做的：

基本上，您所要做的就是在表单中查询数据库中的数据库。为此，您需要在Form中提供DB-Adapter，这是通过Dependency-Injection完成的。由于数据库适配器为required以使表单正常运行，我建议使用Setter-Injection。

在getServiceConfig()内执行此操作：

return array('factories' => array(
    'namespace-form-formname' => function($sm) {
        $dbA  = $sm->get('Zend\Db\Adapter\Adapter');
        $form = new \Namespace\Form\Formname($dbA);

        return $form;
    }
));

这会将Zend\Db\Adapter\Adapter注入到您的表单中，该表单应该已经通过其他配置有效。然后你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。可悲的是，我不能给你一个具体的例子，因为我从未使用Zend\Db，但我认为这会让你开始。

PS：在你的控制器中，调用这样的表格：

$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);

 <?php

                ),
        ));
    $portalId = (isset($params['portalId']) && count($params['portalId']) > 0)?$params['portalId']:array();
        $this->add(array(
