将JavaScript new Date（）转换为php DateTime（）

Question

I have 2 fields in HTML:

<input id="datum" type="date">
<input id="uhrzeit" type="time">

JavaScript:

var datumUhrzeit = new Date($("#datum").val()+","+$("#uhrzeit").val());
console.log(datumuhrzeit);

 "Tue Aug 18 2015 16:45:00 GMT+0200 (Mitteleuropäische Sommerzeit)"

How can I convert "Tue Aug 18 2015 16:45:00 GMT+0200 (Mitteleuropäische Sommerzeit)" in PHP to a DateTime, so that I can save it to postgresql?

Answer 1

You can get unix timestamp from Date object as follows ( see Date.prototype.getTime )

var timestamp = '@' + Math.round(datumUhrzeit.getTime()/1000);

Then when sent on server simply create new datetime object

$datumUhrzeit = new DateTime($timestamp);

If you can't use javascript to create timestamp and you get the the data from form directly you can do something like this, remember to set the timezone:

$datum = $_GET['datum'];
$uhrzeit = $_GET['uhrzeit'];
$datumUhrzeit = DateTime::createFromFormat('Y-m-d H:i:s', $datum . ' ' . $uhrzeit, new DateTimeZone('Europe/Berlin'));

Now as you have saved your date to the database and retrieved it, you can send it back

print $datumUhrzeit->format('U'); // This will print the time as unix timestamp

After that you would create your javascript date object with just the timestamp

var datumUhrzeit = new Date(timestamp * 1000); // timestamp from above

If you for some reason don't want to use unix timestamp you can print it in desired format with format method. Remember to set the timezone beforehand

$datumUhrzeit->setTimezone(new DateTimeZone('Europe/Berlin'));
print $datumUhrzeit->format('Y-m-d H:i:s');

Because javascript doesn't work well with timezones I would advocate you to use unix timestamps when you can. This way you have less problems with timezones.

Answer 2

You can do something like

$datumUhrzeit = 'Tue Aug 18 2015 16:45:00 GMT+0200 (Mitteleuropäische Sommerzeit)';
$datumUhrzeit = substr($datumUhrzeit, 0, strpos($datumUhrzeit, '('));
$resultDate = date('Y-m-d h:i:s', strtotime($datumUhrzeit));
echo $resultDate;

Answer 3

You can use this javascript function to convert the dateObject or date string to your desired format:

/**
 * Formats a dateObject or date string to Y-m-d date
 * Example: Converts  dateObject or date string  Sat Aug 19 2017 00:00:00 GMT+0530 (India Standard Time)   TO  2017-08-19   
 */
function format_date( date )
{
    if (typeof date == "string")
    {
        date = new Date(date);
    }

    var year = date.getFullYear();
    var month = (1 + date.getMonth()).toString();
    month = month.length > 1 ? month : '0' + month;

    var day = date.getDate().toString();
    day = day.length > 1 ? day : '0' + day;

    return year+'-'+month+'-'+day;
}

var dateString = 'Tue Aug 18 2015 16:45:00 GMT+0200 (Mitteleuropäische Sommerzeit)';

var formattedDate = format_date(dateString);//returned formatted date is 2015-08-18

Then you can pass this formatted date to your PHP code where you can use function strtotime to convert this date to your desired format. For ex:

$myFormattedDate = date('d-m-Y', strtotime($_REQUEST['formattedDate']));

try this one

 function myFunction() {
      var content =  document.getElementById("datum").value+","+document.getElementById("uhrzeit").value;
  console.log(content);

  }
