Symfony: Datetime form type with rfc 3339 string input

Question

I'm trying to use a datetime type

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

my form date format is RFC 3339

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

Error

    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

seems that datetime type is only expecting date as string with format 2016-01-04 16:01:25 and this format can't be changed from the form type configs

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

wondering if thats the desired behavior or an issue

Note

both format and date_format options will work on the view data rather than the input data.

Did you actually try the format option? Please note that the view data is both the data that is shown to the user as well as the data entered by the user. If you use your form in an API, the view data is the data sent by the consumer of your API. — xabbuh

@xabbuh i understand except that the model transformer get triggered first and it triggers the error please check the symfony code — trrrrrrm

Looks like something is going wrong for you then. When does the model transformer get triggered with the wrong data? When the form is created or when the request is submitted? And can you show the complete stack trace of that error? — xabbuh

It seems you also need to add format

Refer details here

wondering if thats the desired behavior or an issue

This seems to be behaviour as per documentation, refer 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'))

refer question
