Hi Johannes,
Thank you for your purchase.

Please read our blog post about translation and localization to get a clearer picture of situation. 

If you want just to translate mentioned buttons maybe it would be easiest to just hardcode translation in file 

../wp-content/plugins/wpdatatables/source/class.wpdatatable.php

around line 2016 you can find 

'text' => __('Print','wpdatatables')

just change 'Print' to appropriate text. Similarly you can find text for all other buttons in the code below.

If you want to be able to customize all strings from our plugin you can use approach from that blog post. At some point one of our client translated most of the strings to German language but we keep changing our plugin and that translation is not ready for public release. 

Best regards.

Hi Johannes,

To change that stings you can go in this file 
../wp-content/plugins/wpdatatables/assets/js/wpdatatables/wpdatatables.js and around line 1000 find this code

modal.find('.modal-title').html('Add new entry');

where you can change the Add new entry to your desire.

About the nothing selected dropdown can you please send me the screenshot of it.

Best regards.

Hi Johannes,

You can change that text directly on this file

../wp-content/plugins/wpdatatables/assets/js/bootstrap/bootstrap-select/bootstrap-select.min.js and search for this file

DEFAULTS={noneSelectedText:"Nothing selected"

Just change the string Nothing selected.

About the translation from the blog post:
Can you please send me that file so I can take a look and try to reproduce the issue.

Best regards.

Hi Johannes,

Unfortunately yes until we made all of those strings translatable with the po and mo files.

Can you please tell me did you updated po file from that translation with newest strings and attached it. You can skip most parts in the tutorial just extract zip in languages folder, open .po file with poedit, find strings that you want to translate, translate it and save.

 If you choose German language in wordpress settings everything, our plugin should be translated too.

Can you please tell me can you translate the plugin from the files that I am sending you in attachment.

Best regards.

Hi Johannes,

I find the issue.

The files that you sent me was not properly named.

You must name your files wpdatatables-

Like from your blog post ( attachment 1) 

This is my result from your files after I renamed it. ( attachment 2)

And here are your po and mo files with the wpdatatables- prefix.

Best regards.

Hi Johannes,

You are welcome.

Best regards.
