Question

我试图使用日期时间类型

    $builder->add('start_date', 'datetime', array(
        'widget' => 'single_text',
        'input'  => 'string'
    ));

我的表单日期格式是RFC 3339

    [start_date] => '2016-01-04T16:01:25+00:00'

错误

    The parsed date was invalid, The separation symbol could not be found, Unexpected data found., Unexpected data found., Unexpected data found., Unexpected data found., Unexpected data found., Data missing

似乎datetime类型只期望日期为格式为2016-01-04 16:01:25的字符串，并且此格式无法从表单类型配置中更改

https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Form/Extension/Core/Type/DateTimeType.php#L171

https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Form/Extension/Core/DataTransformer/DateTimeToStringTransformer.php#L68

想知道这是否是理想的行为或问题

注意

format和date_format选项都适用于视图数据而不是输入数据。

Answer 1

您似乎还需要添加格式

参考详情here

想知道这是否是理想的行为或问题

这似乎是根据文档的行为，请参考line 140

// Change the input to a HTML5 date input if
    //  * the widget is set to "single_text"

    //  * the format matches the one expected by HTML5

    //  * the html5 is set to true


add('start_date', 'date', array(
        'widget' => 'single_text',
        'format' => 'c'))

参考question

Answer 2

$builder->add('start_date', 'datetime', array(
        'widget' => 'single_text',
        'input'  => 'string',
        'date_format' => 'yyyy-MM-dd  HH:mm:ss'
    ));

试试这个，希望对你有所帮助
