<?PHP
        	if(!empty($_GET['value_pages'])){
				$getIngDetail = mysqli_query($conn," SELECT * FROM  product_fg1 WHERE  fg_id='".$_GET['value_pages']."' ");
			} else {
				$getIngDetail = mysqli_query($conn," SELECT * FROM  product_fg1 WHERE  id_menu='".$_GET['value']."' ORDER BY fg_id desc ");
					 while($result = mysqli_fetch_assoc($getIngDetail)){
				          $no = ++$no;
		  }
      ?>
     <?PHP
	 	if(!empty($result['id_menu']))
		{
     		 echo"Data Ready";
      ?>
     <?PHP
		}else{
 		  echo"No Product Data !!! ";
		}
	  ?>  
      <?PHP
