初めてPHPのフレームワーク（Yii）を使ってみる その４

まずは復習を兼ねて、新規会員登録フォームを作ってみます。
その後、UserとUserProfileのバリデーションなどを作り上げてみたいと思います。

新規会員登録フォームを作る

UserモデルのCRUD実装コードを自動生成する

Giiを使ってUserモデルのCRUD機能を生成する
Gii->Crud Generator->Model ClassにUserを入力してpreview->Generate

UserモデルのbeforeSave()をオーバーライドする

パスワードはデータベースに登録する前にハッシュをかけるので、beforeSave()をオーバーライドする

User.php

...
    protected function beforeSave() {
        if(parent::beforeSave()) {
            $this->password = CPasswordHelper::hashPassword($this->password);
            return true;
        } else {
            return false;
        }
    }
...

_form.phpの編集とconfirm.phpの作成

特に難しいこともなく、その３のUserProfileと同じように作成、編集する
反復練習大事
ただし_form.phpにはメールアドレスとパスワードの確認入力欄を追加している

/views/user/_form.php

<div class="form">

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'user-form',
    // Please note: When you enable ajax validation, make sure the corresponding
    // controller action is handling ajax validation correctly.
    // There is a call to performAjaxValidation() commented in generated controller code.
    // See class documentation of CActiveForm for details on this.
    'enableAjaxValidation'=>false,
)); ?>

    <p class="note">Fields with <span class="required">*</span> are required.</p>

    <?php echo $form->errorSummary($model); ?>

    <div class="row">
        <?php echo $form->labelEx($model,'mailaddr'); ?>
        <?php echo $form->textField($model,'mailaddr',array('size'=>60,'maxlength'=>128)); ?>
        <?php echo $form->error($model,'mailaddr'); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'verifymailaddr'); ?>
        <?php echo $form->textField($model,'verifymailaddr',array('size'=>60,'maxlength'=>128)); ?>
        <?php echo $form->error($model,'verifymailaddr'); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'password'); ?>
        <?php echo $form->passwordField($model,'password',array('size'=>60,'maxlength'=>32)); ?>
        <?php echo $form->error($model,'password'); ?>
    </div>

    <div class="row">
        <?php echo $form->labelEx($model,'verifypassword'); ?>
        <?php echo $form->passwordField($model,'verifypassword',array('size'=>60,'maxlength'=>32)); ?>
        <?php echo $form->error($model,'verifypassword'); ?>
    </div>

    <div class="row buttons">
        <?php echo CHtml::submitButton('確認画面へ', array('name' => 'confirm')); ?>
    </div>

<?php $this->endWidget(); ?>

</div><!-- form -->

/views/user/confirm.php

<?php
/* @var $this UserController */
/* @var $model User */

$this->breadcrumbs=array(
    'Users'=>array('index'),
    $model->id,
);

$this->menu=array(
    array('label'=>'List User', 'url'=>array('index')),
    array('label'=>'Create User', 'url'=>array('create')),
    array('label'=>'Update User', 'url'=>array('update', 'id'=>$model->id)),
    array('label'=>'Delete User', 'url'=>'#', 'linkOptions'=>array('submit'=>array('delete','id'=>$model->id),'confirm'=>'Are you sure you want to delete this item?')),
    array('label'=>'Manage User', 'url'=>array('admin')),
);
?>

<h1>記入内容確認</h1>

<?php $this->widget('zii.widgets.CDetailView', array(
    'data'=>$model,
    'attributes'=>array(
        //'id',
        'mailaddr',
        'password',
        //'auth',
    ),
)); ?>
<!-- 以下を追加　-->
<div class="form">
<?php 
echo CHtml::statefulForm();
echo CHtml::submitButton('戻る', array('name' => 'back'));
echo CHtml::submitButton('次へ', array('name' => 'finish'));
?>
</form>
</div>

UserController.phpの編集

同様に、UserController.phpも編集する
変えたところはaccessRules()とactionCreate(),actionUpdate()

/controllers/UserController.php

...

    public function accessRules()
    {
        return array(
            /*array('deny', // ログインしている会員は新規登録できない
                'actions'=>array('create'),
                'users'=>array('@'),
            ),*/
            array('allow',  // allow all users to perform 'index' and 'view' actions
                'actions'=>array('create','index','view'),
                'users'=>array('*'),
            ),
            array('allow', // allow authenticated user to perform 'create' and 'update' actions
                'actions'=>array('update'),
                'users'=>array('@'),
            ),
            array('allow', // allow admin user to perform 'admin' and 'delete' actions
                'actions'=>array('admin','delete'),
                'users'=>array('admin'),
            ),
            array('deny',  // deny all users
                'users'=>array('*'),
            ),
        );
    }

...

    public function actionCreate()
    {
        $model=new User;

        // Uncomment the following line if AJAX validation is needed
        // $this->performAjaxValidation($model);

        if(isset($_POST['confirm']))
        {
            $model->attributes=$_POST['User'];
            if($model->validate())
            {
                $this->setPageState('create', $_POST['User']);
                $this->render('confirm', compact('model'));
                return;
            }
        } else if(isset($_POST['back']))
        {
            $model->attributes = $this->getPageState('create');
        }
        else if(isset($_POST['finish']))
        {
            $model->attributes = $this->getPageState('create');
            if($model->save()) {
                // ここで今作ったアカウントで自動ログインする
                $id = new UserIdentity($model->mailaddr, $password);
                $id->authenticate();
                if($id->errorCode===UserIdentity::ERROR_NONE) {
                    Yii::app()->user->login($id, 0);
                }
                $this->redirect(Yii::app()->baseUrl.'?r=userProfile/create');
            }
        }
        $this->render('create', compact('model'));
    }

    /**
     * Updates a particular model.
     * If update is successful, the browser will be redirected to the 'view' page.
     * @param integer $id the ID of the model to be updated
     */
    public function actionUpdate()
    {
        $model=$this->loadModel(Yii::app()->user->id);

        // Uncomment the following line if AJAX validation is needed
        // $this->performAjaxValidation($model);

        if(isset($_POST['confirm']))
        {
            $model->attributes=$_POST['User'];
            if($model->validate())
            {
                $this->setPageState('update', $_POST['User']);
                $this->render('confirm', compact('model'));
                return;
            }
        } else if(isset($_POST['back']))
        {
            $model->attributes = $this->getPageState('update');
        }
        else if(isset($_POST['finish']))
        {
            $model->attributes = $this->getPageState('update');
            if($model->save()) {
                $this->redirect(Yii::app()->baseUrl);
            }
        }
        $this->render('update', compact('model'));
    }

バリデーションを作成する

User.phpとUserProfile.phpのrules()を書き換えて検証ルールを宣言する
（まだとりあえず感があるが...）
これは公式サイトがわかりやすい
検証ルールの宣言

メールアドレスとパスワードに関しては、確認欄を設けているので、verifymailaddrとverifypasswordを新たにプロパティに加えて、rules()にも記述しておく
確認欄の追加の仕方はここがわかりやすかった
verify password yii framework

User.php

...
class User extends CActiveRecord
{

    public $verifymailaddr;
    public $verifypassword;

...

    public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('mailaddr, password', 'required'),
            array('mailaddr', 'length', 'max'=>128),
            array('mailaddr', 'unique', 'message' => Yii::t('app',"This user's email adress already exists.")),
            array('verifymailaddr', 'compare', 'compareAttribute'=>'mailaddr'),
            array('password', 'length', 'max'=>32),
            array('verifypassword', 'length', 'max'=>32),
            array('verifypassword', 'compare', 'compareAttribute'=>'password'),
            array('mailaddr', 'email'),
            // The following rule is used by search().
            // @todo Please remove those attributes that should not be searched.
            array('id, mailaddr, password, auth', 'safe', 'on'=>'search'),
        );
    }

...

Userprofile.php

...

    public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('id, firstname, lastname, kana_firstname, kana_lastname, zipcode, address, phone1', 'required'),
            array('firstname, lastname, kana_firstname, kana_lastname, post, phone1, phone2, fax', 'length', 'max'=>20),
            array('kana_firstname, kana_lastname, kana_corporation', 'match', 'pattern'=>'/^[ァ-ヶｦ-ﾟー]+$/u'),
            array('phone1, phone2, fax', 'match', 'pattern'=>'/^([+]?[0-9 -]+)$/'),
            array('corporation, kana_corporation', 'length', 'max'=>50),
            //array('zipcode, deliverable_zipcode', 'length', 'max'=>10),
            array('zipcode, deliverable_zipcode', 'match', 'pattern'=>'/^[0-9]{3}[-]?[0-9]{4}$/'),
            array('address, deliverable_address', 'length', 'max'=>100),
            array('email2', 'length', 'max'=>128),
            array('email2', 'email'),
            // The following rule is used by search().
            // @todo Please remove those attributes that should not be searched.
            array('id, firstname, lastname, kana_firstname, kana_lastname, corporation, kana_corporation, post, zipcode, address, phone1, phone2, fax, email2, deliverable_zipcode, deliverable_address, point', 'safe', 'on'=>'search'),
        );
    }
