php - 未知 "pagerfanta"函数

Question

我正在使用带有 Symfony 3.3.4 和 Bootstrap 3 的 Pagerfanta 包；

    "php": ">=5.5.9",
    "components/jquery": "^3.2",
    "doctrine/doctrine-bundle": "^1.6",
    "doctrine/orm": "^2.5",
    "incenteev/composer-parameter-handler": "^2.0",
    "kriswallsmith/assetic": "^1.4",
    "oyejorge/less.php": "v1.7.0.14",
    "sensio/distribution-bundle": "^5.0.19",
    "sensio/framework-extra-bundle": "^3.0.2",
    "symfony/assetic-bundle": "^2.8",
    "symfony/monolog-bundle": "^3.1.0",
    "symfony/polyfill-apcu": "^1.0",
    "symfony/swiftmailer-bundle": "^2.3.10",
    "symfony/symfony": "3.3.*",
    "twig/twig": "^1.0||^2.0",
    "twitter/bootstrap": "^3.3",
    "white-october/pagerfanta-bundle": "^1.0"

然后我的 AppBundle 中有一个模板，它扩展了 base.html.twig:

{% extends 'base.html.twig' %}

{% block body %}
    <nav class="navbar navbar-inverse navbar-fixed-top">

...

    {% block content %}{% endblock %}

{% endblock %}

它又由页面模板扩展:

{% extends '@AppBundle/index.html.twig' %}

{% block submenu %}
    <a href="{{ path('site_new') }}" class="btn btn-success"><i class="fa fa-plus"></i> Create</a>
{% endblock %}
{% block title %}
    Manage Sites
{% endblock %}
{% block body %}

    {{ pagerfanta(pager, 'twitter_bootstrap3') }}

{% endblock %}

调用模板

    $adapter = new DoctrineORMAdapter($qb);
    $pager = new Pagerfanta($adapter);
    $pager->setMaxPerPage(20);
    $pager->setCurrentPage(intval($this->getSessionPage()));

    $data = $pager->getCurrentPageResults();
    return $this->render('@AppBundle/site/index.html.twig', [
        'pager' => $pager,
        'data' => $data,
        'order' => $order,
        'form' => $form->createView()
    ]);   

但是我得到了

Unknown "pagerfanta" function.

Exception: Twig_Error_Syntax

好像没有包含这个 Twig 函数，但我看不出还需要包含什么。 Pagerfanta 也在我的 AppKernel.php 中

Answer 1

看起来您忘记将 WhiteOctoberPagerfantaBundle 添加到 AppKernel.php 中，导致 PagerfantaExtension 未加载，因此{{ pagerfanta() }} 函数未定义。

$bundles = array(
    // ...
    new WhiteOctober\PagerfantaBundle\WhiteOctoberPagerfantaBundle(),
);
