CONTROLLER

class ProfileController extends Controller {
    public function actionSave() {   
        $patients = new Patients;
        $questions = new PatientsRegistrationQuestions;
        $payments = new PaymentTypes;
        $gender = new Gender;
        if (isset($_POST['Patients'])) {
            $patients->save_personal_data();
            $patients->name = $_POST['Patients']['name'];
            $patients->mobile = $_POST['Patients']['mobile'];
            $patients->email = $_POST['Patients']['email'];
            $patients->dob = $_POST['Patients']['dob'];
            $patients->weight = $_POST['Patients']['weight'];
            $patients->gender_id = $_POST['Patients']['gender_id'];
            $patients->height = $_POST['Patients']['height'];
            //$patients->payment_type_id = $_POST['Patients']['payment_type_id'];
            $patients->activation_date = '0000-00-00';
            $patients->credit = 0;
            $patients->archive = 0;
            $patients->balance = 0;
            $patients->first_login = 0;
            $patients->guide_status = 0;
            $patients->passcode = '';
            $patients->patient_id = $questions->patient_id;
            // $patients->gender_id = $gender->gender_id;
            if ($patients->validate()) {
                $patients->save(false);
            } else {
        $this->redirect(Yii::app()->request->urlReferrer);
        }
   }
}

Answer 1

基于某些模型保存记录的机制是这样的：

public function actionSave()
{
    $model = new ModelName;

    // ...

    if(isset($_POST['ModelName']))
    {
        $model->attributes = $_POST['ModelName'];

        if($model->validate())
        {
            $model->save(false);
            $this->redirect(...); //redirect to some page after successful save
        }
    }

    $this->render('viewName', array(
        'model'=>$model // <-- passing variable to view, so that you can show error messages and data in form
    ));
}

现在，在视图文件中，检查模型是否有错误：

<?php if($model->hasErrors()): ?>
    // show what is stored in $model->getErrors() and show it using foreach loop for example
<?php endif; ?>

顺便说一下，建议使用CHtml类来呈现表单元素而不是手动编写，或者更好的方法 - 使用CActiveForm。更多信息，例如：http://www.larryullman.com/2011/01/20/creating-forms-with-the-yii-framework/

Answer 2

我不需要在我的控制器中创建一个chtml表单

？php echo $ form-＆gt; errorSummary（$ model）; ？＆GT;

显示错误消息yii html表单
