在我的基本应用项目中，我正在尝试集成注册表单，但出现此错误：

无效的验证规则：规则必须同时指定属性名称和验证器类型。

我的代码在这里。

注册表格.php

<?php
namespace app\models;
use yii\base\Model;
use app\models\User;

/**
 * Signup form
 */
class SignupForm extends Model
{
    public $user_fname;
    public $user_email;
    public $user_password_hash;
    /**
     * @inheritdoc
     */


    public function rules()
    {
        return [
            [['user_fname','user_email', 'user_password_hash'], 'required'],
            // rememberMe must be a boolean value

            ['user_password_hash','match','pattern'=>'$\S*(?=\S*[a-z])(?=\S*[A-Z])(?=\S*[\d])\S*$','message'=>'Password must have atleast 1 uppercase and 1 number '],
            [['user_password_hash'],'string','min'=>6],
            //email validation
            ['user_email','email']
            [['user_email'], 'string', 'max' => 255],
            [['user_fname'], 'string', 'max' => 45],
        ];
    }
    /**
     * Signs user up.
     *
     * …

我在主查询中有一个子查询，如下所示：

$subquery = (new Query())->select('COUNT(project_sup_id)')
    ->from('project_supervisors AS sup')
    ->where(['AND','sup.project_ref_id = p.project_id']);

$uQuery =(new Query())->select(['project_id','supcount' => $subquery])
    ->from('projects AS p')
    ->join('LEFT JOIN','project_supervisors AS sup','sup.project_ref_id = project_id')
    ->andWhere('IF(supcount>0, sup_project_status=1, project_status=1)');

我正在尝试根据逻辑编写 where 条件，即，如果从子查询获得的计数大于零，则 where 条件必须为sup_project_status=1else project_status=1。在普通的Mysql中，很容易在where里面写if条件，但在yii2中我不明白如何写。

我想创建ActiveForm没有模型,以防万一.我尝试过dynamicModel但是我遇到了一些错误:

use yii\base\DynamicModel;
$model = DynamicModel::validateData(compact('KOMENTAR'), [
   [['KOMENTAR'], 'string', 'max' => 128],
]);

这是我想要创建的表单

<br>
<?php $form = ActiveForm::begin([
    'method' => 'post',
]); ?>

<?= $form->field($model, 'KOMENTAR')->textarea(['rows' => 6])->label(false) ?>

<div class="form-group">
    <?= Html::submitButton('POST', ['class' => 'btn btn-primary']) ?>
</div>

这是错误

Getting unknown property: yii\base\DynamicModel::KOMENTAR

我想通过composer安装yii2,它给了我一个错误

这是错误:

我是新的yii2,所以我有这个问题.我想使用fileinput所以我添加fileinput这个网址 http://www.yiiframework.com/doc-2.0/guide-input-file-upload.html 如果我用文件输入创建新模型(选择视频),如果我删除模型中的项目:**Ber Request(#400)无法验证您的数据提交.如果我选择图像,它可以正常工作如何在yii2上传视频？

我的日志:

请帮我？谢谢 !

我正在为Yii2搜索密码强度计.我为Yii1 找到了这篇文章.我在protected那里看到了目录.我找不到这个文件夹了.它是否可用于基本应用程序模板或高级应用程序模板？

我是Yii2的新手,使用Gii工具,我为简单的'Message'类创建了模型和CRUD组件,其中一个字段'content'映射到tbl_message.

我收到错误,当尝试使用findByPk函数检索一个消息对象时,如下所示:

$message = Message::model()->findByPk(4);

错误信息:

Call to undefined method app\models\Message::model()

我有一个表格

  <?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
 <?php echo $form->field($userformmodel, 'user_image')->fileInput(); ?>
 <?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?>
 <?php ActiveForm::end(); ?>

我正在上传表单中的文件并提交

In the model I have written the code as

 public function rules()
{
    return [
        [['user_image'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg']
    ];
}

 public function upload()
{
    if ($this->validate()) {
        $this->user_image->saveAs('uploads/' . $this->user_image->baseName . '.' . $this->user_image->extension);
        return true;
    } else {
        return false;
    }
}

在我的控制器中

 public function actionProfile()
{ …

为了设置错误操作，我在控制器中添加了此代码

public function beforeAction($action) {
    if ($action->id == 'error')
        $this->layout = 'iframe-main.php';

    $this->enableCsrfValidation = false;
    return parent::beforeAction($action);
}

但它不起作用。错误布局显示在默认布局中

我被卡住了.我正在尝试从命令shell运行一些函数.我正在使用基本项目中的HelloController.当我运行php yii hello它的工作正常并且索引函数正在运行但是如果我尝试运行不同的函数,就像php yii hello/create我收到此错误一样 -

错误:未知命令.

我将create函数添加到此控制器.奇怪的是,当我跑步时,php yii我正在看到创建命令.我的控制器代码

namespace app\commands;

use yii\console\Controller;
use Yii;

class HelloController extends Controller
{

    public function actionIndex($message = 'hello world')
    {
        echo $message . "\n";
    }
    public function actionCreate($message = 'hello world')
    {
        echo $message . "\n";
    }

}

更新: 我的配置文件是

Yii::setAlias('@tests', dirname(__DIR__) . '/tests');

$params = require(__DIR__ . '/params.php');
$db = require(__DIR__ . '/db.php');

return [
    'id' => 'basic-console',
    'basePath' => dirname(__DIR__),
    'bootstrap' => ['log', 'gii'],
    'controllerNamespace' …
