Month variable in Polish language

Hello,

Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

Unfortunately, doesn’t have control over the translation of the month. You may need to create your own custom variable and return it after using ucwords() function which is a PHP function.

Please try the filter below and use the shortcode %shortcode_var_name%:

add_action( 'rank_math/vars/register_extra_replacements', function(){
	rank_math_register_var_replacement(
	   'shortcode_var_name', [
	   'name'        => esc_html__( 'VAR name', 'rank-math' ),
	   'description' => esc_html__( 'VAR description', 'rank-math' ),
	   'variable'    => 'shortcode_var_name',
	   'example'     => shortcode_var_name_call_back(),
	   ],
	   'shortcode_var_name_call_back'
   );
});
function shortcode_var_name_call_back(){
	return "YOUR VARIABLE VALUE";
}

Please note that this is just a placeholder code. You still need to modify this code to achieve the desired logic which is now out of our scope of support.

You would need to return the details of the attribute under the function shortcode_var_name_call_back.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
