Hello Hubert.

Thank you for your purchase.

There's no built-in option to translate the date picker to German, but here's a workaround:

1. Open ../wp-content/plugins/wpdatatables/assets/js/wpdatatables/wdt.funcs.js and add this code under the comments "Apply datetimepicker" around line 147:

moment.locale('de', {
        months : ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
        monthsShort : ["jan", "feb", "mär", "apr", "mai", "jun", "jul", "aug", "sep", "okt", "nov", "dec"],
        weekdaysMin : ["So", "Mo", "Di", "Mi", "Do", "Fr", "Sa"],
        week : {        dow : 1 // Monday is the first day of the week
        }});

Then, below that find this line of code:

$(this).datetimepicker(
            {
                format: wdtDateFormat,
                showClear: true,
                keepOpen: true,
                useCurrent: false
            }
        )

And modify it to look like this (add "locale: 'de' "):

$(this).datetimepicker(
            {
                format: wdtDateFormat,
                showClear: true,
                keepOpen: true,
                useCurrent: false,
                locale: 'de'
            }
        )

Then, do the same for around line 190 (add "locale: 'de' "):

$(this).datetimepicker(
            {
                format: wdtDateFormat,
                showClear: true,
                keepOpen: true,
                useCurrent: false,
                locale: 'de'
            }
        )
            .off('dp.show')
            .on('dp.show', function () {
                $(this).parent().find('div.bootstrap-datetimepicker-widget').addClass('wdt-datetimepicker-modal');
                if (!_.contains(['MM/Y','MMM Y','Y'], wdtDateFormat)) {
                    wdtAddDatePlaceholders($(this));
                }
            });
    });

Do not forget to add a comma ( , ) after " useCurrent: false " (see code above). If you forget that, this will not work.

2. Open ../wp-content/plugins/wpdatatables/source/class.wdttools.php and around line 920 add the following line of code:

wp_enqueue_script('wdt-moment', WDT_JS_PATH . 'moment/locale/de.js', array(), false, true);

So it should look like this in the end:

wp_enqueue_script('wdt-moment', WDT_JS_PATH . 'moment/moment.js', array(), WDT_CURRENT_VERSION, true);
wp_enqueue_script('wdt-moment', WDT_JS_PATH . 'moment/locale/de.js', array(), false, true);
wp_enqueue_script('wdt-bootstrap-datetimepicker', WDT_JS_PATH . 'bootstrap/bootstrap-datetimepicker/

This also changes the datepicker starting day, so the week starts from Monday, not Sunday.

Please let me know if this helps.

Best regards.

Hi Hubert.

You seem to have added this one too many times in wdt.funcs.js:

moment.locale('de', {
        months : ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
        monthsShort : ["jan", "feb", "mär", "apr", "mai", "jun", "jul", "aug", "sep", "okt", "nov", "dec"],
        weekdaysMin : ["So", "Mo", "Di", "Mi", "Do", "Fr", "Sa"],
        week : {        dow : 1 // Monday is the first day of the week
        }});

The class.wdttools.php is good, so please try with the attached .js file.

As for "From" and "To", please paste this line of code in class.wdttools.php, at line 359:

from'                      => __('Von', 'wpdatatables'),

And at line 403:

'to'                        => __('Zu', 'wpdatatables')

It won't let me upload the .php file as an attachment, otherwise I would have provided that as well.

Please let me know if this works.

Best regards.

Honestly, Hubert, I don't know why it won't work on your end.

See how it looks in my local environment:

Can you, please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. You can write credentials here just check Private Reply so nobody can see them except us.

Also, please make sure the Plugin Editor is available from the Dashboard, so I can take a look at the files.

Best regards.

Hi Hubert.

Yeah, that was my bad. Sorry.

I forgot to tell you about one more line of code:

In ../wp-content/plugins/wpdatatables/assets/js/wpdatatables/wdt.frontend.min.js I found this line:

$(this).datetimepicker({format:wdtDateFormat,showClear:!0,keepOpen:!0,useCurrent:!1})

It is a minified file, so you can only search through it. Then, I added " locale: 'de' ":

$(this).datetimepicker({format:wdtDateFormat,showClear:!0,keepOpen:!0,useCurrent:!1,locale:'de'})

And then, I had to disable the "Use minified wpDataTables Javascript" slider located in main settings of wpDataTables, under Custom JS and CSS tab:

Now it works in front-end as well. I also changed "Maerz" to "März", so I believe we got it covered completely.

Please take a look and let me know if everything looks good.

Best regards.

Thank you, Hubert, and you're welcome!

I'm glad I could be of service.

If you have any more issues or questions feel free to open a new ticket, we will gladly help.

We'd greatly appreciate it if you could take a minute and leave a Review on CodeCanyon on this link. Thanks!
