hi, my code needs a lot of work, but i want to be able to let users vote on their favorite car, update the database, and display the new updated data for the top ten cars listed. i want to prevent multiple votes by ip but i dont know how, but any help with the voting part of the code GREATLY appreciated, as my google tutorials seem to only show premade code.

here is the page so far.

Code:

<?php
include("connect1.php");


ini_set('display_errors', 1);
  error_reporting(E_ALL);   // GREAT SNIPPET FOR DEBUGGING OUTPUTS ERRORS TO SCREEN */

////////////////////////////////////////
////////////////////////////////////////


// escape username and password for use in SQL//person said on board "looks fine" like this
//to prevent sql injections
  
$make= $_POST['make'];
$model  = $_POST['model'];
$year  = $_POST['year'];
$color   = $_POST['color'];
 

$make = mysql_real_escape_string($make);
$model = mysql_real_escape_string($model);
$year = mysql_real_escape_string($year);
$color = mysql_real_escape_string($color);

$find = $_POST['find'];
 

    
 

 if(isset($_POST['Submit'])){
 
  $vote=0;
 $vote++;
 
  echo (" You have voted for a ".$color. " ".$make." ".$model. " ...year: ".$year.".");
 
mysql_query("INSERT INTO cars (make, model, year ,color , vote ) VALUES('$make','$model', '$year' , '$color',' $vote'"); //ON DUPLICATE KEY UPDATE courtesy = courtesy + $courtesy,  stability = stability + $stability, loyalty = loyalty + $loyalty, attitude = attitude + $attitude, votes = votes + $votes");
 

}//end isset
 
  
  
  
  //output the cars row into an array and the list the top ten
 if(isset($_POST['submit'])){
  $query="SELECT make, model, year, color, vote 
FROM cars
WHERE votes (is the most number of votes) ;
$result=mysql_query($query); 

if(mysql_num_rows($result) > 0)
{
$topcars = mysql_fetch_array($result); //put cars row into an array $topcars

 }
 
 echo( "Top ten cars ". $carone."<br>".$cartwo."<br>". $carthree. "<br>".$carfour."<br>".
 $carfive."<br>".$carsix. "<br>". $carseven. "<br>".$careight."<br>".$carnine."<br>".$carten .<br>");
 
 }//end isset
    
?>
