表单页面
------------------------------------------------------------------------------------------
第一: 先使用一下类
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\validators\Volidator;
use yii\captcha\Captcha;
第二: Yii 框架自带的各种表单的写法
$form = ActiveForm::begin(['action'=>'index.php?r=form1/index','method'=>'post','options' => ['enctype' => 'multipart/form-data'] ]); ?>
<?= $form->field($model, 'username',['enableAjaxValidation'=>true]) ?>
<?= $form->field($model, 'password')->passwordInput() ?>
<?= $form->field($model, 'okpassword')->passwordInput() ?>
<?= $form->field($model, 'age') ?>
<?= $form->field($model, 'sex')->radioList(['男' => '男', '女' => '女']); ?>
<?= $form->field($model, 'hobby[]')->checkboxList(['游泳' => '游泳', '跑步' => '跑步', '音乐' => '音乐', '学习' => '学习']) ?>
<?= $form->field($model, 'phone',['enableAjaxValidation'=>true]) ?>
<?= $form->field($model, 'captcha')->widget(Captcha::className(), ['captchaAction'=>'form1/captcha',
'template' => '<div class="row"><div class="col-lg-3">{image}</div><div class="col-lg-6">{input}</div></div>',
]) ?>
<?= $form->field($model, 'email',['enableAjaxValidation'=>true]) ?>
<?= $form->field($model, 'image')->fileInput() ?>
<div class="form-group">
<div class="col-lg-offset-1 col-lg-11">
<?= Html::submitButton('Login', ['class' => 'btn btn-primary']) ?>
</div>
</div>
<?php ActiveForm::end() ?>

模型层
----------------------------------------------------------------------------------------------
先使用一下文件上传类 use yii\web\UploadedFile;
public $captcha;
/**
* @验证规则
*/
public function rules()
{
return [
[['age'], 'integer'],
[['image'], 'file','skipOnEmpty'=>false, 'extensions'=>'png,jpg,gif'],
//验证不为空
['username', 'required', 'message' => '{attribute}不能为空'],
['password', 'required', 'message' => '{attribute}不能为空'],

['email', 'required', 'message' => '{attribute}不能为空'],
['age', 'required', 'message' => '{attribute}不能为空'],
['sex', 'required', 'message' => '{attribute}不能为空'],
['hobby', 'required', 'message' => '{attribute}不能为空'],
//去掉空格
['username', 'filter', 'filter' => 'trim'],
['password', 'filter', 'filter' => 'trim'],
['okpassword', 'filter', 'filter' => 'trim'],
['phone', 'filter', 'filter' => 'trim'],
['email', 'filter', 'filter' => 'trim'],
['age', 'filter', 'filter' => 'trim'],
//唯一性验证
[['phone'], 'unique','message'=>'{attribute}已经被占用'],
[['username'], 'unique','message'=>'{attribute}已经被占用'],

//正则匹配验证

[['username'],'match','pattern'=>'/^[a-zA-Z_]\w{6,20}$/','message'=>'{attribute}6-20位数字字母下划线组成，不能以数字开头'],
[['age'],'match','pattern'=>'/^18|19|([2-4]\d)|50$/','message'=>'{attribute}为18-50以内整数'],
//['age', 'integer','min'=>18,'max'=>50],
[['phone'],'match','pattern'=>'/^1[3,5,8]\d{9}$/','message'=>'{attribute}为11位13,15,18开头'],
['okpassword', 'required', 'message' => '{attribute}不能为空'],
['okpassword','compare','compareAttribute'=>'password','message'=>'{attribute}与{attribute}一致'],
['captcha', 'captcha', 'message'=>'请输入正确地{attribute}','captchaAction'=>'form1/captcha'],
];
