No, you haven't.
A rating system requires a server-side language to be installed and enabled on your server, since it must store data server-side.
You have come to the right section... You can code a rating system in PHP.... You will need a database to store the information but the SYSTEM itself can be coded in php...
Here is Something Like what I use:
Put The Following Code into a php file:
<?
// User settings
$rater_ip_voting_restriction = true; // restrict ip address voting (true or false)
$rater_ip_vote_qty=1; // how many times an ip address can vote
$rater_already_rated_msg="You have already rated this item. You were allowed ".$rater_ip_vote_qty." vote(s).";
$rater_not_selected_msg="You have not selected a rating value.";
$rater_thankyou_msg="Thankyou for voting.";
$rater_generic_text="this item"; // generic item text
$rater_end_of_line_char="\n"; // may want to change for different operating systems
if(!isset($rater_id)) $rater_id=1;
if(!isset($rater_item_name)) $rater_item_name=$rater_generic_text;
// DO NOT MODIFY BELOW THIS LINE
$rater_filename='item_'.$rater_id.".rating";
$rater_rating=0;
$rater_stars="";
$rater_stars_txt="";
$rater_rating=0;
$rater_votes=0;
$rater_msg="";
// Rating action
if(isset($_REQUEST["rate".$rater_id])){
if(isset($_REQUEST["rating_".$rater_id])){
while(list($key,$val)=each($_REQUEST["rating_".$rater_id])){
$rater_rating=$val;
}
$rater_ip = getenv("REMOTE_ADDR");
$rater_file=fopen($rater_filename,"a+");
$rater_str="";
$rater_str = rtrim(fread($rater_file, 1024*8),$rater_end_of_line_char);
if($rater_str!=""){
if($rater_ip_voting_restriction){
$rater_data=explode($rater_end_of_line_char,$rater_str);
$rater_ip_vote_count=0;
foreach($rater_data as $d){
$rater_tmp=explode("|",$d);
$rater_oldip=str_replace($rater_end_of_line_char,"",$rater_tmp[1]);
if($rater_ip==$rater_oldip){
$rater_ip_vote_count++;
}
}
if($rater_ip_vote_count > ($rater_ip_vote_qty - 1)){
$rater_msg=$rater_already_rated_msg;
}else{
fwrite($rater_file,$rater_rating."|".$rater_ip.$rater_end_of_line_char);
$rater_msg=$rater_thankyou_msg;
}
}else{
fwrite($rater_file,$rater_rating."|".$rater_ip.$rater_end_of_line_char);
$rater_msg=$rater_thankyou_msg;
}
}else{
fwrite($rater_file,$rater_rating."|".$rater_ip.$rater_end_of_line_char);
$rater_msg=$rater_thankyou_msg;
}
fclose($rater_file);
}else{
$rater_msg=$rater_not_selected_msg;
}
}
// Get current rating
if(is_file($rater_filename)){
$rater_file=fopen($rater_filename,"r");
$rater_str="";
$rater_str = fread($rater_file, 1024*8);
if($rater_str!=""){
$rater_data=explode($rater_end_of_line_char,$rater_str);
$rater_votes=count($rater_data)-1;
$rater_sum=0;
foreach($rater_data as $d){
$d=explode("|",$d);
$rater_sum+=$d[0];
}
$rater_rating=number_format(($rater_sum/$rater_votes), 2, '.', '');
}
fclose($rater_file);
}else{
$rater_file=fopen($rater_filename,"w");
fclose($rater_file);
}
// Assign star image
if ($rater_rating <= 0 ){$rater_stars = "./img/00star.gif";$rater_stars_txt="Not Rated";}
if ($rater_rating >= 0.5){$rater_stars = "./img/05star.gif";$rater_stars_txt="0.5";}

if ($rater_rating >= 5 ){$rater_stars = "./img/5star.gif";$rater_stars_txt="5";}
// Output

This is the part you will need to edit:
// User settings
$rater_ip_voting_restriction = true; // restrict ip address voting (true or false)
$rater_ip_vote_qty=1; // how many times an ip address can vote
$rater_already_rated_msg="You have already rated this item. You were allowed ".$rater_ip_vote_qty." vote(s).";
$rater_not_selected_msg="You have not selected a rating value.";
$rater_thankyou_msg="Thankyou for voting.";
$rater_generic_text="this item"; // generic item text
$rater_end_of_line_char="\n"; // may want to change for different operating systems
