从String中设置Symfony2中的DateTime和Time

Question

In my entity, i have two fields, one type DateTime and other type Time.

I'm trying to do this:

$time = "05:45";
$date = "01-09-2015"

$entity = new Entity();
$entity->setDate(new \DateTime($date));
$entity->setTime($time);

In both case, Symfony told me that the code has problems with format.

I also tried:

->setDate(new Datetime($date));
->setDate(DateTime::createFromFormat($date, 'd-m-Y));
->setTime(strtotime($time));

Always with the same result.

If anybody could help me, i'll be thankful.

Thanks

UPDATED

Now, I tried

$date = strtotime($date);
$time = strtotime($time);
$entity->setDate(date("d-m-Y", $date));
$entity->setTime(date("H:i",$time));

And Symfony told me:

Error: Call to a member function format() on a non-object

in vendor/doctrine/dbal/lib/Doctrine/DBAL/Types/TimeType.php at line 53   -
    public function convertToDatabaseValue($value, AbstractPlatform $platform)
    {
        return ($value !== null)
            ? $value->format($platform->getTimeFormatString()) : null;
    }
    /**

I also tried this:

$dateObject = new DateTime();
$date = $dateObject->format('d-m-Y');
$time = $dateObject->format('H:i');
$entity->setDate($date);
$entity->setTime($time);

And symfony told me:

Attempted to call method "format" on class "Symfony\Component\Validator\Constraints\DateTime". On line "$date = $dateObject->format('Y-m-d');"

Thanks for the help

Updated - Resolve

Finally, yesterday a resolved the problem, using this:

$entity->new Entity();
$entity->setDate(\DateTime::createFromFormat('d-m-Y',$date));
$entity->setTime(\DateTime::createFromFormat('H:i',$time));

Thanks!

Answer 1

Symfony doesn't know where to find DateTime class, so it is searching in the wrong (default) namespace. Use a leading \\ .

Moreover you inverted the format argument and the time argument in the createFromFormat() function.

So your code becomes:

$time = "05:45";
$date = "01-09-2015"

$entity = new Entity();
$entity->setDate(\DateTime::createFromFormat('d-m-Y', $date));
$entity->setTime(\DateTime::createFromFormat('H:i', $time));

By the way, are you sure you really need to split Date and Time in your entity? It depends on your case but you could do this instead (only one object to manipulate):

$time = "05:45";
$date = "01-09-2015"

$entity = new Entity();
$entity->setDateTime(\DateTime::createFromFormat('d-m-Y H:i', $date.' '.$time));

Answer 2

Check out http://php.net/manual/de/datetime.createfromformat.php to be sure that your format fits.

Or check mktime(hour,minute,second,month,day,year) Or check strtotime(time,now) eg here http://www.w3schools.com/php/php_date.asp

Answer 3

Do it like this:

$dateObject = new DateTime();
$date = $dateObject->format('Y-m-d');
$time = $dateObject->format('H:i:s'); // or $time = $dateObject->format('H:i'); if you dont want to have the seconds

$entity = new Entity();
$entity->setDate($date);
$entity->setTime($time);
