yii 表单如何写，action指向哪里？

1. 文本框:textInput();
2. 密码框:passwordInput();
3. 单选框:radio(),radioList();
4. 复选框:checkbox(),checkboxList();
5. 下拉框:dropDownList();
6. 隐藏域:hiddenInput();
7. 文本域:textarea(['rows'=>3]);
8. 文件上传:fileInput();
9. 提交按钮:submitButton();
10. 重置按钮:resetButtun();

<?php
    $form = ActiveForm::begin(['action' => ['test/getpost'], 'method' => 'post',]); ?>

<? echo $form->field($model, 'username')->textInput(['maxlength' => 20]) ?>

<? echo $form->field($model, 'password')->passwordInput(['maxlength' => 20]) ?>

<? echo $form->field($model, 'sex')->radioList(['1' => '男', '0' => '女']) ?>

<? echo $form->field($model, 'edu')->dropDownList(['1' => '大学', '2' => '高中', '3' => '初中'], ['prompt' => '请选择', 'style' => 'width:120px']) ?>

<? echo $form->field($model, 'hobby')->checkboxList(['0' => '篮球', '1' => '足球', '2' => '羽毛球', '3' => '乒乓球']) ?>

<? echo $form->field($model, 'info')->textarea(['rows' => 3]) ?>

<? echo $form->field($model, 'userid')->hiddenInput(['value' => 3]) ?>

<? echo Html::submitButton('提交', ['class' => 'btn btn-primary', 'name' => 'submit-button']) ?>
