If variation has no price – PHP needed

  • Hi all,

    Using a filter I display all variations for variable product, also the ones that has no price.

    No I want to display a message only when variation has no price, but I don’t know which PHP to use to make this IF statement. Can anybody help me with that?

    function wsis_wholesale_warning_variations() {

	if(???variation has no price???){
		echo '<div>Test message</div>';
	}
}

    Kind regards,

    Willem
