yii 表單如何寫，action指向哪里？

文本框:textInput(); 密碼框:passwordInput(); 單選框:radio(),radioList(); 復選框:checkbox(),checkboxList(); 下拉框:dropDownList(); 隱藏域:hiddenInput(); 文本域:textarea(['rows'=>3]); 文件上傳:fileInput(); 提交按鈕:submitButton(); 重置按鈕: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'=>'大學','2'=>'高中','3'=>'初中'], ['prompt'=>'請選擇','style'=>'width:120px']) ?> <? echo $form->field($model, 'file')->fileInput() ?> <? echo $form->field($model, 'hobby')->checkboxList(['0'=>'籃球','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']) ?> <? echo Html::resetButton('重置', ['class'=>'btn btn-primary','name' =>'submit-button']) ?> <?php ActiveForm::end(); ?>
