Question

我是Yii的新手，我正试图以“正确”的方式完成我的初始项目。我创建了一个CFormModel类，它需要三个字段来查询一些数据，一个CForm配置来构造表单，一个CController将它们绑定在一起（所有这些都在下面给出）。

数据请求需要一个帐户，这可能来自几个不同的地方。我认为检索它应该在控制器中。但是，我不知道如何从控制器进入表单的隐藏“帐户”字段，以便它在提交后进入分配给CFormModel的参数。更一般地说，我知道如何从CController传递到查看脚本，但不知道如何传递给CForm。注册表（Yii::app()->params[]）是我最好的选择吗？

我想我可以将它从表单（和必填字段）中删除，然后等待在提交操作（actionSummaries）中填充它。这是否打破了CForm的意图？有最好的做法吗？即使采用这种解决方案，有人可以解决第一个问题，以防再次出现吗？

欢迎任何其他温和的批评。

模型/ SummariesForm.php

class SummariesForm extends CFormModel
{
    public $account;
    public $userToken;
    public $year;

    public function rules () {...}

    public function fetchSummary () {...}

    static public function getYearOptions () {...}
}

视图/帐户/ select.php

<?php
$this->pageTitle=Yii::app()->name;
?>

<div class="form">
    <?php echo $form->render(); ?>
</div>

控制器/ AccountController.php

class AccountController extends CController
{
    public $layout = 'extranet';

    public function actionSelect ()
    {
        $model = new SummariesForm();

        // retrieve account
        require_once 'AccountCookie.php';

        /*
         *
         * Here, I insert the account directly into the
         * model used to build the form, but $model isn't
         * available to selectForm.php. So, it doesn't
         * become part of the form, and this $model doesn't
         * persist to actionSummaries().
         * 
         */
        $model->account = AccountCookie::decrypt();
        if ($model->account === false) {
            throw new Exception('Unable to retrieve account.');
        }

        $form = new CForm('application.views.account.selectForm', $model);
        $this->render('select', array(
            'form'    => $form,
            'account' => $model->account,
        ));
    }

    public function actionSummaries ()
    {
        $model = new SummariesForm();
        if (isset($_POST['SummariesForm'])) {
            $model->attributes = $_POST['SummariesForm'];
            /*
             *
             * Should I just omit "account" from the form altogether
             * and fetch it here? Does that break the "model"?
             * 
             */
                if ($model->validate() === true) {
                try {
                    $summaries = $model->fetchSummary();
                } catch (Exception $e) {
                    ...
                    CApplication::end();
                }

                if (count($summaries) === 0) {
                    $this->render('nodata');
                    CApplication::end();
                }

                $this->render('summaries', array('model' => $model, 'summaries' => $summaries));
            } else {
                throw new Exception('Invalid year.');
            }
        }
    }

}

视图/帐户/ selectForm.php

<?php
return array(
    'title' => 'Select year',
    'action' => Yii::app()->createUrl('Account/Summaries'),
    'method' => 'post',

    'elements' => array(
        'account' => array(
            'type'  => 'hidden',
            'value' => $account,
        ),
        'userToken' => array(
            'type'  => 'hidden',
            'value' => /* get token */,
        ),
        'year' => array(
            'type'  => 'dropdownlist',
            'items' => SummariesForm::getYearOptions(),
        ),
    ),

    'buttons' => array(
        'view' => array(
            'type'  => 'submit',
            'label' => 'View summaries',
        ),
    ),
);

Answer 1

答案是否定的。从控制器传递到视图时，您可以看到$form变量几乎像数组一样。解决方案是在$account中添加更多属性selectForm model，并将其视为其他元素。如果你想提交它的价值，我不认为将新字段留在表格之外。
