Question

I’m trying to implode an array of values that are wrapped in a i18n function as shown here:

<?php echo implode( ', ', __($joblanguages, 'my-text-domain') ); ?>

I’m getting the following error message:

Warning: Illegal offset type in isset or empty in /Applications/XAMPP/xamppfiles/htdocs/vemas-2012/wp-includes/pomo/translations.php on line 72

Is there any way to fix this and get the values in the chosen language?

Thanks in advance!

Answer 1

I think the function you need is array_map().

Your problem is that WP’s __() function wants a single string to translate, whereas you want to translate a whole bunch of strings all at once. array_map() will do this for you. Something like this should do the trick:

implode(array_map(function($e) {return __($e,'my-text-domain');},$joblanguages);

Hope that helps.
