Hi, Zeba / Здраво!

I will have to check about this with our developers.

I know that the language of the date picker is being determined by a 3rd Party HTML5 library.

If a language you need is supported in this library, and if the current page has this language locale,

then this language will be applied to the Date Picker.

If that language is not supported by this library, then the calendar will be in English.

-

But i will still double-check with our developers, if that workaround from the said ticket can still work,

and if there is any better way/workaround.

As soon as they confirm, we will report back right away.

Thank you for your patience.

Hey, Zeba.

No problem, i will follow up on it with our devs.

Still no confirmation, but going to keep you posted.

Thank you for your patience, as always.

Hi, Zeba.

No problem, i am happy to help and advise as much as possible.

We got word from our developers.

They confirm that the workaround from that ticket 2671239 is still the same.

You can upvote this feature suggestion here

https://features.wpdatatables.com/51 ,

and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like ( it is also available in the plugin dashboard), where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

2. In regards to the steps for that workaround, as far as we can see the lines are more/less the same,

if you search in each file for these lines/pieces of code that need to be changed, you should have no issues in finding them.

I personally use either Visual Studio Code, or Sublime as code editors of choice,

and with both we can find the lines with "CTRL+F" combination.

The example for German:

1. Open ../wp-content/plugins/wpdatatables/assets/js/wpdatatables/wdt.funcs.js 

and add this code under the comments "Apply datetimepicker" around line 147

( The "Apply datetimepicker" is giving only one result in the code)

:

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", "dez"],
        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 around line 169:

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

It is more less still on the same line,

but to future proof it, it is best to search for this entire code with CTRL+F  : 

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

 there is only one result with this particular code, so there is no mistake :

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

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

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

Then, do the same for around line 183 (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));
                }
            });
    });

On my end, when i already added all the other lines, now it is around line 233.

For the rest of the workaround, you should be able to use the same logic, in terms of "search and replace pieces of code", it works on our end,

but let us know if you encounter any issues and we can check it out.

2. Open ../wp-content/plugins/wpdatatables/source/class.wdttools.php and around line 1469 add the following line of code:

wp_enqueue_script('wdt-moment-de', 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-de', 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.

3. Open this file: 

wp-content/plugins/wpdatatables/assets/js/wpdatatables/wdt.frontend.min.js

Since this is a minified file, you have to search for the following line of code:

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

and change it to look like this:

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

The last step is to go to main settings of wpDataTables, under Custom JS and CSS  tab, and disable the "Use minified wpDataTables Javascript" check-box.

-

Of course, the example we have is for changing the language to German, for other languages you can modify it as needed.

Let us know if that helps, and if you encounter any issues with the workaround.

Thank you.

Hi, Zeba.

I am happy to see that this helped.

To be honest, it took me a few minutes as well to follow along and check all the lines,

while i was testing this on my local Site, checking if anything got messed up, this workaround does have a few steps, indeed.

I hope that everything works as it should on your end,

we will certainly be here if any assistance is needed.

You're very welcome for the support.

Best wishes from our Team.
