我正在尝试在 Silex 应用程序中使用 twig 呈现 Symfony 表单。我正在使用 Symfony 2 表单库、Symfony Bridge Twig Forms Extension 和 Twig。
这是我的引导文件：
require_once __DIR__ . '/../app/silex.phar';
$app = new Silex\Application();
$app['debug'] = true;
// Set up the autoloader
require_once __DIR__ . '/../app/vendor/.composer/autoload.php';
// Load Configuration into container
$parser = new Symfony\Component\Yaml\Parser();
$config = $parser->parse(file_get_contents(__DIR__ . '/../app/config/config.yml'));
$app['config'] = $config;
// Set up Symfony bridge (nice twig functions)
$app->register(new Silex\Provider\SymfonyBridgesServiceProvider(), array(
'symfony_bridges.class_path' => __DIR__ . '/vendor/symfony/twig-bridge',
));
// Set Up Templating
$app->register(new Silex\Provider\TwigServiceProvider(), array(
'twig.path' => __DIR__ . '/../app/views',
'twig.class_path' => __DIR__ . '/../app/vendor/twig/twig/lib',
));
// Set Up Database
$app->register(new Silex\Provider\DoctrineServiceProvider(), array(
'db.options' => array(
'driver' => $app['config']['db']['driver'],
'host' => $app['config']['db']['host'],
'user' => $app['config']['db']['user'],
'password' => $app['config']['db']['password'],
'dbname' => $app['config']['db']['dbname']
),
'db.dbal.class_path' => __DIR__ . '/vendor/doctrine/doctrine-dbal/lib',
'db.common.class_path' => __DIR__ . '/vendor/doctrine/doctrine-common/lib',
));
// Set up the Symfony forms component
$app->register(new Silex\Provider\FormServiceProvider());
// Routes
$app->get('/', function() use($app)
{
return $app['twig']->render('index.twig', array());
});
$app->get('/info', function() use($app)
{
return $app['twig']->render('info.twig', array());
});
$app->get('/register', function() use($app)
{
$builder = $app['form.factory']->createBuilder(new MppInt\Form\Type\RegisterType() )
->add('id', 'text')
->add('firstName', 'text')
->add('lastName', 'text')
->add('email', 'password')
->add('password', 'text');
$form = $builder->getForm();
return $app['twig']->render('register.twig', array('form' => $form->createView()));
});
$app->run();
我收到以下错误：
Twig_Error_Runtime：变量“已禁用”不存在。
堆栈跟踪非常大，但这里是前两个条目：
在 /nfs/personaldev/bwaine/mpp-audit/app/vendor/twig/twig/lib/Twig/Template.php 第 303 行
在 Twig_Template->getContext(array('value' => '', 'attr' => array(), 'form' => object(FormView), 'id' => 'register_firstName', 'name' => ' firstName', 'full_name' => 'register[firstName]', 'errors' => array(), 'read_only' => false, 'required' => true, 'max_length' => null, 'pattern' => null, 'size' => null, 'label' => 'Firstname', 'multipart' => false, 'types' => array('field', 'text'), 'type' => 'text') , '禁用') 在 /nfs/personaldev/bwaine/mpp-audit/app/vendor/twig/twig/lib/Twig/Environment.php(314) : eval()'d 代码行 986
有没有人知道发生了什么？
编辑 -
我认为“禁用”变量在默认模板中。
来自供应商/symfony/twig-bridge/Symfony/Bridge/Twig/Resources/views/Form/form_div_layout.html.twig
{% block widget_attributes %}
