Symfony2日期表单类型：致命错误：在非对象上调用成员函数setLenient（）

Question

thanks to Stof on IRC i know the answer now. I just wanted to share it, in case someone stumbles upon the same problem.

The problem

When you have field type datetime:

/**
 * @ORM\Column(type="datetime", name="released_at")
 */
protected $released_at;

and in form type you use date form type:

$builder
      ->add('released_at', 'date', array(
          'widget' => 'single_text',
          'format' => 'yyyy-MM-dd',
      ));

and you're getting this error:

Fatal error: Call to a member function setLenient() on a non-object in (...)\vendor\symfony\src\Symfony\Component\Form\Extension\Core\Type\DateType.php on line 64

Answer 1

The solution is

Try this test

<?php

$formatter = new \IntlDateFormatter();

if($formatter === null)
  echo 'null!';
else
  echo 'else';

If you get null, it means your php / intl version is buggy and you need to upgrade.

In my case, I was running @ Windows 7 64bit machine, Wampserver2 with PHP 5.3.8.

Upgradeing to PHP 5.3.10 or higher did the trick.

Also if you are getting:

(..path..)\StubIntlDateFormatter::setLenient() is not implemented. Please install the 'intl' extension for full localization capabilities.

upgrade to Symfony 2.0.16.

Cheers and once again, TYVM Stof!
