    'type'      => new UsersEmailAddressesType(),

Answer 1

在 symfony 食谱中有一个关于如何在表单中嵌入集合的示例。那里的解决方案如下所示（适用于您的表单示例）：

<ul>
{% for email in form.email %}
    <li>{{ form_row(email.address) }}</li>
{% endfor %}
</ul>

由于您想将输入彼此相邻放置，您可能需要检查 loop.index 是否为odd，even或者divisibleby()例如像这样：

{% for email in form.email %}
    {% if loop.index is odd %}
        <li class="float-left">
    {% else %}
        <li class="float-right">
    {% endif %}
    {{ form_row(email.address) }}</li>
{% endfor %}
