提交后 CJuiDatePicker 在文本字段中保留值

Question

我有一个搜索模块，用户在 CJuiDatePicker 中选择日期。 当我单击提交时，页面将加载但我的日期选择器中的日期将消失。我怎样才能保留我的领域中的价值？ 值的搜索很好。它正在返回正确的数据。但是字段中的值消失了。有人可以帮忙吗？

我的表格中有这个。

<div class="panel-body">

        $form = $this->beginWidget( 'CActiveForm',

这是我的控制器代码：

class EvaluationController extends Controller {

    public function actionIndex()
    { 
        Helper_Site::initializePage();
        LoginForm::checkLogin();
        $user = LoginForm::getUser();

        if($user->username == $user->company_id){
            Yii::app()->getController()->redirect(array("site/initiallogin"));
        }else{
            $model = new EvaluationDetails('search');
            $model->unsetAttributes();  // clear any default values
            if (isset($_GET['EvaluationDetails'])) {
                $model->attributes = $_GET['EvaluationDetails'];

            $modelE->unsetAttributes();  // clear any default values

                    if (count(Evaluation::model()->findAll()) == 0) {
                        $search_date_start = date('Y-m-d', strtotime("-1 month"));
                        $search_date_end = date('Y-m-d');

                        $search_date_start = date("Y-m-d", strtotime(Evaluation::model()->find($criteria)->start_date));

                }*/
                }
            }// RESET BTN

            $this->render('index', array('model' => $model, 'modelE' => $modelE, 'search_date_start' => $search_date_start, 'search_date_end' => $search_date_end, 'search' => $search));
        }
    }

Answer 1

当使用带有小部件的参数模型时，不要这样设置值：

$this->widget('zii.widgets.jui.CJuiDatePicker', array(
    'model' => $model,
    'attribute' => 'start_date',
    'htmlOptions' => array(
        'value' => $search_date_start
    )
));

在模型（更好的方式）或控制器中执行。

控制器的简短示例：

if (isset($_POST['EvaluationDetails'])) {
    $model->attributes = $_POST['EvaluationDetails']; // specify model scenario and rules() to set only needed params
} else {
    $model->start_date = date('Y-m-d', strtotime("-1 month"));
}

您还检查$_POST['start_date'] 的价值。当您为 CJuiDatePicker 指定模型参数时，您还应该考虑模型名称 $_POST['EvaluationDetails']['start_date']。
