Rate.php

PHP Code:

$mysqli 
= new mysqli("localhost","root","root""rating") or die  ("Couldnt connect to the database!"); 

 if (isset(
$_POST['pos']))
 
$post_rating $_POST['rating']; 

 
$find_data $mysqli->query("SELECT * FROM rates WHERE pos='$pos'"); 
 while(
$row $mysqli->fetch_assoc($find_data)) 

   { 
  
$id $row['id']; 
  
$current_rating $row['rating']; 
  
$current_hits $row['hits'];  

   } 

   
$new_hits $current_hits 1
   
$update_hits $mysqli->query("UPDATE rates SET hits = '$new_hits'     WHERE id='$id'"); 

   
$pre_rating $current_rating $post_rating
   
$new_rating $pre_rating $new_hits

   
$update_rating $mysqli->query("UPDATE rates SET rating = '$new_rating' WHERE id='$id'");
