PHP 第71页

直接上代码

$mainMenuItems = array();
	$mainMenuItems[] = [
		'label' => '<i class="glyphicon glyphicon-th-large"></i>首页',
		'type' => 'raw',
		'url' => ['site/index'],
		'options' => [
			'class' => ''
		],
	];

echo Menu::widget([
    'options' => [
	'class' => 'nav-tabs nav-stacked'
    ],
    'items' => $mainMenuItems
]);

如上的视图文件在页面中显示时这样的：
“<i class="glyphicon glyphicon-th-large"></i>首页”
而不是以html的形式显示，应该怎么办呢，知道的兄弟能否告知，不甚感激。

'type' => 'html',

The "fxp/composer-asset-plugin" plugin requires composer-plugin-api 1.0.0, this *WILL* break in the future and it should be fixed ASAP (require ^1.0 for example).

先执行这个。yiichina的文档太old了，需要升级

// 先执行sql: SELECT * FROM customer LIMIT 100;
// SELECT * FROM orders WHERE customer_id IN (1,2,...)
$customers = Customer::find()->limit(100)
->with('orders')->all();
foreach ($customers as $customer) {
// 在这个循环的时候就不会再执行sql了
$orders = $customer->orders;
// ...handle $orders...
}

照着文档里这么做，然后获取到的$orders是一个对象，如下：

我要怎么处理这个对象，以获取我两个数据表数据的集合，初学者求教

$customers = Customer::find()->limit(100)
->with('orders')->**asArray()**->all();
楼上正解，加上asArray()返回的就是正常的数组了

yii2和bootstrap怎么配合，比如我用了$form->field()会自动生成一些html,其中的css是明显和bootstrap有关系的，这个时候如果我想改一下css怎么办。
例如，默认生成的是这个样子的：

但是我嫌它太长了，用options加了class=col-lg-6，但是换行了
于是我用了template：

<?= $form->field($model, 'modules_name',['template'=>"<div class='col-lg-6'>{label}\n{input}\n{hint}\n{error}</div>"])->textInput() ?>

这样的话，显示正常了，但是不至于每个field都加一个template吧，有没有其他方案解决啊
或者是推荐个其他方案。

统一的样式可以在开头统一配置，个性化的设置只能每个filed单独配置。
在页面里加js代码块，直接用jquery加你想应用的样式
表示yii2的activeform非常不灵活

需要批量插入学生啊,但是password字段如何搞定?

我想直接在mysql里面插入,密码是怎么加密的?有方法吗?

如果密码可以一样，你就在yii2存一条，然后拷贝出来，
如果不一样，每次都要加密，就直接在程序里操作了，不要直接在mysql了。
如果是安装了yii2-user模块，直接mysql肯定不行，通过程序也很简单：

我配置了三个virtualHost.
使用这三个vituralHost可以访问相应的应用 。现在下面三个的配置已经生效。

但是我现在想用localhost访问 www目录时，却直接被转到basic/web。换句话说就是直接显示basic应用的内容了。

Apache中没有捕获到的主机名，默认使用第一个虚拟主机。
问题描述不明不白..
确认你的配置已生效，
确定各端口都正常访问，
再确认没有别的规则指向www目录

model

刚接触YII的一个新手

你要看一下 HTML 上的 ActiveForm
你取用的方式是 name = “xxxx”
我記得ActiveForm 是已陣列方式呈現 name =”ModelName[……]”
如果不確定的話:
你大可直接 $_POST 看看傳入值是長甚麼樣子
楼主应该打开firebug，查看一下网络传输参数，一看便知。

在yii2中写迁移脚本，怎么添加普通索引，怎么写注释。

迁移脚本中不为空可以用not_null()这个方法，默认值有defaultValue()。

那么普通索引以及注释呢？

非常感谢大家的回复，下面是我实现的方式，献丑了、、、

$this->createTable(self::TBL_NAME, [
            'id' => Schema::TYPE_PK,
            'user_id' => Schema::TYPE_INTEGER . ' NOT NULL COMMENT "用户ID"',
            'path' => Schema::TYPE_STRING . ' NOT NULL COMMENT "路径"',
            'created_at' => Schema::TYPE_INTEGER . ' NOT NULL COMMENT "上传时间"'
        ], $tableOptions);

普通索引用$this->index()
参考yii自带的migrate文件

在postman插件中使用是正常的，但是使用post创建新的用户的时候传参数一直为空，查看了数据库插入了一条数据，不过数据的用户名和密码为空，更新时间什么的就不为空，再次执行就报错了，请问什么原因
代码是这样的：

<?php
/**
 * Created by PhpStorm.
 * Date: 11/13/15
 * Time: 5:25 PM
 */

namespace api\controllers;


use yii\rest\ActiveController;

class UserController extends ActiveController
{
    public $modelClass = 'common\models\User';

}

Body
x-www-form-urlencoded

如题，不在同一个module里，怎么调用其他module的动作action。或者在frontend里有一个module,在这个子module怎么调用frontend的动作呢？谢谢。

比如，在子模块里，想$this->redirect(['site/index'])总是失败的，一般跳到子模块下的site/index，加上frontend/site/index却无法访问。

在 frontend/site/index 前面加上 / 即可：
