yii2 怎样为某个 field 单独指定 template?

[lsoknet]

如题，比方说有两个 input，每个 input 后面的样式是不同的，怎样指定 template 呢？

[ 'template' => '

{error}{input}

'] ]); field($model, 'phone')->textInput(['placeholder' => '手机号']); ?> field($model, 'password')->passwordInput(['placeholder' => '密码']); ?>

原始 html 是这样的：

<input type="text" name="phone" class="form-control" placeholder="手机号">

<input type="password" name="password" class="form-control" placeholder="密码">

[ 'template' => '
{error}{input}
'] ]); field($model, 'phone')->textInput(['placeholder' => '手机号','class '='a']); ?> field($model, 'password')->passwordInput(['placeholder' => '密码','class '='b']); ?>
