我不习惯寻求帮助，但对于这个问题，我承认我自己无法解决。
我在同一页面上有2个表单（来自fosuserbundle的loginform和registerform） 两种形式都有效。
现有用户尝试注册时出现问题。
我创建了一个RegistrationFailureListener，如果已经存在电子邮件（例如），则会在同一页面上重定向用户。
但register/路线上显示的错误不会在此页面上显示2个表格。
我不知道如何在我的网页上发送这些表单错误。
对不起，我的英文！

我的RegisterController与fosuser registercontroller

$form = $event->getForm();

我改变了我的观点：
{% trans_default_domain 'FOSUserBundle' %}
{% if error is defined and error is not null%}
<div class="alert alert-danger col col-md-12">{{ error.messageKey|trans(error.messageData, 'security') }}</div>
{% endif %}
<div class="p-0 card col col-md-5 col-12">
<h3 class="p-2 bg-primary text-white">Se connecter</h3>
<form action="{{ path("fos_user_security_check") }}" method="post" class="p-2">
{% if csrf_token is defined%}
<input type="hidden" name="_csrf_token" value="{{ csrf_token }}"/>
{% endif %}
<div class="form-group">
<label for="username">{{ 'security.login.username'|trans }}</label>
<input type="text" id="username" class="form-control" name="_username" value="{% if last_username is defined %}{{ last_username }}{% endif %}"
required="required"/>
</div>
<div class="form-group">
<label for="password">{{ 'security.login.password'|trans }}</label>
<input type="password" id="password" class="form-control" name="_password" required="required"/>

</label>
</div>
<div class="form-group" align="center" style="margin-top: 54%">
<input type="submit" class="btn btn-primary" id="_submit" name="_submit"
value="{{ 'security.login.submit'|trans }}"/>
</div>
</form>
</div>
{% if form is defined %}
<div class="p-0 card col col-md-5 col-12">
<h3 class="p-2 bg-primary text-white">S'inscrire</h3>
{{ form_start(form, {'method': 'post', 'action': path('fos_user_registration_register'), 'attr': {'class': 'fos_user_registration_register p-2'}}) }}
{{ form_widget(form) }}
{{ form_errors(form) }}
{{ form_widget(form._token) }}
<div align="center">
<input type="submit" class="btn btn-primary" value="{{ 'registration.submit'|trans }}" />
</div>
{{ form_end(form) }}
</div>
{% else %}
<div class="p-0 card col col-md-5 col-12">
<h3 class="p-2 bg-primary text-white">S'inscrire</h3>
{{ render(controller('TNSUserBundle:Registration:register')) }}
</div>
{% endif %}
最后在我看来我测试是否定义了表单var，如果是，我显示表单，否则我从RegisterController调用表单
我不知道这是否正确，但我的表单错误会显示，并且我会在右页重定向！
如果它可以帮助别人......
