Question

如何在activeform中一行显示多个field

Answer 1

这个和activeform没有任何关系。和你的布局有关，这两行不过是生成input的html tag而已。因为yii是用的bootstrap作为前端，具体如下：
<div class="col-lg-5">
<?php $form = ActiveForm::begin(['id' => 'contact-form']); ?>
<div class="row">
<div class="col-lg-6">
<?= $form->field($model, 'name') ?>
</div>
<div class="col-lg-6">
<?= $form->field($model, 'email') ?>
</div>
</div>
<?= $form->field($model, 'subject') ?>
<?= $form->field($model, 'body')->textArea(['rows' => 6]) ?>
<?= $form->field($model, 'verifyCode')->widget(Captcha::className(), [
'template' => '<div class="row"><div class="col-lg-3">{image}</div><div class="col-lg-6">{input}</div></div>',
]) ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'name' => 'contact-button']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
</div>`
