Php 单击“提交”后无法提交表单

您好，我想在Symfony中单击submit按钮创建表单并将记录插入mysql表。 我是新来的。我已经创建了表单，但提交时没有响应。这是我的密码

DefaultController.php

index.html.twig

我的输出如下图所示

我的问题是，当我点击提交按钮时，它不会返回响应，并且我无法保存我的记录。请帮我解决这个问题。

我认为您需要在twig中添加表单标签：

{{ form_start(form) }}

//all form widgets

//submit button

{{ form_rest(edit_form) }} <-- so it renders the hidden ones like the csrf token

</form>

您需要像这样使用form_start、form_rest和form_end：

{% block gender_widget %}
{% spaceless %}
    {% if form %}
    {{ form_start(form) }}
        <ul {{ block('widget_container_attributes') }}>
        {% for child in form %}
            <li>
                {{ form_widget(child) }}
                {{ form_label(child) }}
            </li>
        {% endfor %}
        </ul>
    {{ form_rest(form) }}
    {{ form_end(form) }}
    {% else %}
        {# just let the choice widget render the select tag #}
        {{ block('choice_widget') }}
    {% endif %}
{% endspaceless %}
{% endblock %}

Thanx你@Hornth。。。我得到了它

{% block gender_widget %}
    {% spaceless %}
        {% if form %}
            <ul {{ block('widget_container_attributes') }}>
            {% for child in form %}
                <li>
                    {{ form_widget(child) }}
                    {{ form_label(child) }}
                </li>
            {% endfor %}
            </ul>
        {% else %}
            {# just let the choice widget render the select tag #}
            {{ block('choice_widget') }}
        {% endif %}
    {% endspaceless %}
{% endblock %}
{% block container %}

{% endblock%}
