สอบถามเรื่อง javascript ส่งค่าไปเข้าในลูป php หน่อยครับ

if(!is_bg_color1 && clicks%4==0){
        console.log("n");
         //var test1 = '<img/yes.png"';
         $.each($('.yes td'), function(index, item) {
            if (item.innerHTML === '') {
               item.innerHTML = '<img src=img/no.png width=35 height=35>';
               return false;
            }
         });
          //test1 ++;
         //sum1++;
      }

<?php
if  (){ 

	$q_devalue = "UPDATE  users SET credit=credit-:credit WHERE id=:id";
	$result_last_login = $sqlite->prepare($q_devalue);
	$result_last_login->execute(array(
		'credit' => 1,
    'id' => $_SESSION['test']['id']   
));
}
?>
