    You need to use .find()/.children() as input is a child not a sibling. Additionally use .val() to get the current value

    var comment = $(this).find('.proid').val();
    

    instead of

    var comment = $(this).next('.proid').attr('value');

    You could also serialize all the inputs of the current form and run through each one like this :

    $('.commentform').on('submit', function(e){
        var formInputs = jQuery(this).serializeArray();
        jQuery.each(formInputs, function(i, field){
            console.log(field.name + " : " + field.value);
        });
    });
