我有一個用於編輯用戶記錄的表單。它第一次更新了記錄，但是當我再次按下更新按鈕時，它會向我顯示一個空白屏幕，並且它也會將圖片取消。我想不出什麼我doign錯 下面是我的代碼Yii更新案例顯示空屏幕
public function actionEditProfile($affusername = NULL) {
$this->layout = 'layout_home';
if ($this->VarifyUser($affusername) && Yii::app()->user->id) {
$model = new Users('edit'); //apply rules if user comes directly to signup page
// uncomment the following code to enable ajax-based validation
if (isset($_POST['ajax']) && $_POST['ajax'] === 'editprofile-form') {
CActiveForm::validate($model);
Yii::app()->end();
}
if (isset($_POST['Users'])) {
$the_image = CUploadedFile::getInstance($model, 'image');
if (is_object($the_image) && get_class($the_image) === 'CUploadedFile') {
$model->image = $the_image;
}
if (is_object($the_image)) {
$file_name = Yii::app()->user->id . '.' . $model->image->extensionName;
$move = $model->image->saveAs(Yii::getPathOfAlias('webroot') . '/themes/myproject/images/users/' . $file_name);
$_POST['Users']['image'] = $file_name;
}
$model->attributes = $_POST['Users'];
if ($model->validate()) {
// form inputs are valid, do something here
if ($model->updateByPk(Yii::app()->user->id, $_POST['Users'])) {
//$this->setFlashSuccess("Unable to register user, please try again");
$this->setFlashSuccess('Updated successfully, now redirecting.');
//$this->redirect($this->base_url);
} else {
$this->setFlashError("Unable to update user, please try again");
return false;
}
} else {
print_r($model->getErrors());
echo 'validation fail';
exit;
}
}
$user_data = Users::model()->getUsersByUserName($affusername); //getting user information
//print_r($user_data);
//$model=new Users('nonfb-create'); //apply rules if user comes directly to signup page
$this->render('editprofile', array('model' => $model, 'data' => $user_data,));
} else {
$this->redirect($this->base_url);
}
}
我的看法是

您應該在操作中放置一些日誌以查看執行錯誤的位置！ – darkheir
