好的，首先我正在使用Yii 2基本版而不是高级版。
好的，我已经做到这一点，以便我的登录功能可以从数据库中提取数据，并将其作为硬编码的用户。然后，我在索引视图中显示我的数据库中所有管理员的网格视图及其ID。我试图创建一个创建页面，管理员可以在其中创建另一个管理员。
我确实设法让这个工作，但是对于我的生活，我无法找到我做了什么使这个功能停止工作。
模型\ user.php的
<?php
namespace app\models;
use yii\base\NotSupportedException;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;
use yii\data\ActiveDataProvider;
/**
* User model
*
* @property integer $id
* @property string $username
* @property string $authkey
* @property string $password
* @property string $accessToken
*/
class User extends ActiveRecord implements IdentityInterface
{
/**
* @inheritdoc
*/
public static function tableName()
{
return 'Users';
}
public function rules(){
return [
[['username','password'], 'required']
];
}
public static function findAdmins(){
$query = self::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
return $dataProvider;
}
/**
* @inheritdoc
*/
public static function findIdentity($id)
{
return static::findOne(['id' => $id]);
}
/**
* @inheritdoc
*/
public static function findIdentityByAccessToken($token, $type = null)
{
throw new NotSupportedException('"findIdentityByAccessToken" is not implemented.');
}
/**
* Finds user by username
*
* @param string $username
* @return static|null
*/
public static function findByUsername($username)
{
return static::findOne(['username' => $username]);
}
/**
* @inheritdoc
*/
public function getId()
{
return $this->id;
}
/**
* @inheritdoc
*/
public function getAuthKey()
{
return static::findOne('AuthKey');
}
/**
* @inheritdoc
*/
public function validateAuthKey($authKey)
{
return static::findOne(['AuthKey' => $authKey]);
}
/**
* Validates password
*
* @param string $password password to validate
* @return boolean if password provided is valid for current user
*/
public function validatePassword($password)
{
return $this->password === $password;
}
}
视图\管理员\的index.php
<?php
use yii\helpers\Html;
use yii\grid\GridView;
/* @var $this yii\web\View */
$this->title = 'Admins';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="site-about">
<h1><?= Html::encode($this->title) ?></h1>
<p>
<?= Html::a('Create Admin', ['create'], ['class' => 'btn btn-success']);?>
</p>
<?php
if(isset($user_id)){
print_r($user_id);
}
?>
<?= GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
'id',
'username',
'password',
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
</div>
这样可以正常连接我的数据库。它显示正确的列等。
现在我将向您展示两个不起作用的视图，一个呈现_form.php的create.php
视图\管理员\ create.php：
<?php
use yii\helpers\Html;
/* @var $this yii\web\View */
$this->title = 'Create Admin';
$this->params['breadcrumbs'][] = ['label' => 'admin', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
if(isset($username)){
print_r($username);
echo '</br>';
print_r($password);
}
?>
<div class="site-about">
<h1><?= Html::encode($this->title) ?></h1>
<?= $this->render('_form',[
'model' => $model
]);
?>
</div>
视图\ admin_form.php：
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
/* @var $model app\models\Users */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="admin-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'username')->textInput(); ?>
<?= $form->field($model, 'password')->textInput(); ?>
<div class="form-group">
<?= Html::submitButton('create', ['class' => 'btn btn-success']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
现在终于我的控制器了：
控制器\ AdminController.php：
<?php
namespace app\controllers;
use Yii;
use yii\web\Controller;
use yii\filters\VerbFilter;
use yii\filters\AccessControl;
use app\models\User;
class AdminController extends Controller
{
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['post'],
],
],
];
}
public function actions()
{
return [
'error' => [
'class' => 'yii\web\ErrorAction',
],
'captcha' => [
'class' => 'yii\captcha\CaptchaAction',
'fixedVerifyCode' => YII_ENV_TEST ? 'testme' : null,
],
];
}
public function actionIndex()
{
$searchModel = new User;
$dataProvider = $searchModel->findAdmins();
return $this->render('index',[
'dataProvider' => $dataProvider
]);
}
public function actionCreate(){
$model = new User;
$request = Yii::$app->request;
$post = $request->post();
$username = "usernameStandard";
$password = "passwordStandard";
if($model->load(Yii::$app->request->post())){
$username = $post['User']['username'];
$password = $post['User']['password'];
}
return $this->render('create',[
'model' => $model,
'username' => $username,
'password' => $password
]);
}
}
好的，所以当我尝试这样做时，我会从create.php填充表单（使用渲染的_form.php）。当我点击创建按钮。我print_r（）发布结果，以确保它没有问题，它确实再次使用发布结果呈现页面。但是，它不会在我的数据库中创建新用户。
真的被困在这里有人可以帮忙吗？
答案 0 :(得分：0)
嗯，您应该只是保存您的模型......例如：
public function actionCreate()
{
$model = new User;
if($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['index']);
}
return $this->render('create',[
'model' => $model,
]);
}
