Symfony2 FOSUserBundle 重写表单

Question

我正在尝试更改应用程序中注册表单的模板，以便我可以向其中添加一些其他 HTML。这是/My/UserBundle/Resources/views/Registration/register.html.twig 文件:

{% extends "MyUserBundle::layout.html.twig" %}

{% block fos_user_content %}
<section class="register site-content">
    <header>
        <h1>{{ 'layout.register'|trans({}, 'FOSUserBundle') }}</h1>
    </header>
    <div class="block">
        {% include "FOSUserBundle:Registration:register_content.html.twig" %}
    </div>
</section>
{% endblock fos_user_content %}

我已经成功覆盖了layout.html.twig:

{% extends 'MyMainBundle::layout.html.twig' %}

{% block title %}{{ site_name }}{% endblock %}

{% block content %}
    {% for key, message in app.session.getFlashes() %}
    <div class="{{ key }}">
        {{ message|trans({}, 'FOSUserBundle') }}
    </div>
    {% endfor %}
    {% block fos_user_content %}{% endblock %}
{% endblock %}

以及 form.html.twig:

{% extends 'FOSUserBundle::form.html.twig' %}

{% block field_row %}
    <li class="form_row">
        {{ form_label(form) }}
        {{ form_errors(form) }}
        {{ form_widget(form) }}
    </li>
{% endblock field_row %}

{% block form_widget %}
    <ul {{ block('container_attributes') }}>
        {{ block('field_rows') }}
        {{ form_rest(form) }}
    </ul>
{% endblock form_widget %}

配置部分:

# FOS User Configuration
fos_user:
    db_driver: orm
    firewall_name: main
    user_class: My\UserBundle\Entity\User
    from_email:
      address: %admin_email%
      sender_name: %site_name%
    template:
      engine: twig
      theme: MyUserBundle::form.html.twig

我已清除缓存。

每当我去

http://localhost/register/

apache 会挂起直到超时。

我能弄清楚的最好消息是，PHP 最大执行消息显示它在第 16 行缓存中的 Twig 模板上崩溃。该行是 function doGetParent(...) 文件是:

<?php

/* FOSUserBundle::form.html.twig */
class __TwigTemplate_9cf68a2af1db50466c556a735bcdeba0 extends Twig_Template
{
    public function __construct(Twig_Environment $env)
    {
        parent::__construct($env);

        $this->blocks = array(
            'field_row' => array($this, 'block_field_row'),
            'form_widget' => array($this, 'block_form_widget'),
        );
    }

    protected function doGetParent(array $context)
    {
        return "FOSUserBundle::form.html.twig";
    }

    protected function doDisplay(array $context, array $blocks = array())
    {
        $this->getParent($context)->display($context, array_merge($this->blocks, $blocks));
    }

    // line 3
    public function block_field_row($context, array $blocks = array())
    {
        // line 4
        echo "    <li class=\"form_row\">
        ";
        // line 5
        echo $this->env->getExtension('form')->renderLabel($this->getContext($context, "form"));
        echo "
        ";
        // line 6
        echo $this->env->getExtension('form')->renderErrors($this->getContext($context, "form"));
        echo "
        ";
        // line 7
        echo $this->env->getExtension('form')->renderWidget($this->getContext($context, "form"));
        echo "
    </li>
";
    }

    // line 11
    public function block_form_widget($context, array $blocks = array())
    {
        // line 12
        echo "    <ul ";
        $this->displayBlock("container_attributes", $context, $blocks);
        echo ">
        ";
        // line 13
        $this->displayBlock("field_rows", $context, $blocks);
        echo "
        ";
        // line 14
        echo $this->env->getExtension('form')->renderRest($this->getContext($context, "form"));
        echo "
    </ul>
";
    }

    public function getTemplateName()
    {
        return "FOSUserBundle::form.html.twig";
    }

    public function isTraitable()
    {
        return false;
    }
}

它也在第65行的\vendor\twig\lib\Twig\Template.php上超时，这是public function getParent(array $context )

很明显 getParent 存在一些问题，但我不知道这意味着什么或如何修复它。

根据 FOSUserBundle 文档:

The easiest way to override a bundle's template is to simply place a new one in your app/Resources folder. To override the layout template located at Resources/views/layout.html.twig in the FOSUserBundle directory, you would place you new layout template at app/Resources/FOSUserBundle/views/layout.html.twig.

As you can see the pattern for overriding templates in this way is to create a folder with the name of the bundle class in the app/Resources directory. Then add your new template to this folder, preserving the directory structure from the original bundle.

在我的项目中，正如他们所说，我覆盖了 FOSUserBundle 的布局，它的工作就像一个魅力。

因此，您需要以同样的方式创建app/Resources/FOSUserBundle/views/Registration/register.html.twig。 (或您想要覆盖的表单)

编辑

好的，我刚刚意识到您已选择扩展 FOSUserBundle。在这种情况下，您需要在包内执行此操作，而不是 app/Resources/ 。但你不需要放

{% extends 'FOSUserBundle::form.html.twig' %}

FOSUserBundle 将检测到您正在覆盖该 bundle 并将自动扩展。

您还需要告诉您的包 FOSUserBundle 是它的父包。

class YourBundle extends Bundle
{
    public function getParent()
    {
        return 'FOSUserBundle';
    }
}
