PHP only returns the the first value : This has 3 rows and 3 buttons each rows. So, when I input a value at the first row and click it's button, it inserts the data. And then when I input at the second row and click its button, it inserts the value at the first row. And there's also something wrong with the button. I think it's because they have the same div class. Is there any way or solution for this? 
//AJAX + JQUERY.

		$(.btn).click(function() {                                    
              $getComment = $(".divComment").val();
		      $getId= $(".inputId").val();

		      $("#divHolder").load("insertData.php",{
			      passComment: $getComment ,
			      passId: $getId
		      });
	    });
