Rating not add with ajax in wordpress

Question

I have a problem There is a rating system on songs (Its not my code i debugging it). but it could not add or update or show me the rating.

here is my code: Ajax.js

function bindEvents() {
                $(cssSelector.rating_succes).css('display','none');
                //Set the new rating when the user clicks
                $(cssSelector.ratingLevel).click(function() {
                    var $this = $(this), rating = $this.parent().children().index($this) + 1, index;

                    var trackname   =   $(cssSelector.title+':first').text();

                    var postdata1   =   'action=my_special_ajax_call5&rating='+rating+'&trackname='+trackname;  
                    alert(postdata1);
                    jQuery.ajax({
                        type:'POST',
                        url:ajaxurl,
                        cache:false,
                        data: postdata1,
                        beforeSend:function(){

                        },
                        success:function(res){
                            $(cssSelector.rating_succes).html(res).fadeIn(500).delay(1000).fadeOut(500);
                            //window.setTimeout(function(){location.reload()},2000);
                        }
                });
                    $this.prevAll().add($this).addClass(attr(cssSelector.ratingLevelOn)).end().end().nextAll().removeClass(attr(cssSelector.ratingLevelOn));
                });
            }

Proccess.php

function implement_ajax5(){

global $wpdb;
$table = $wpdb->prefix."songs";
$table1 = $wpdb->prefix."rating";

$song_title = strip_tags($_POST['trackname']);
$rating_value = strip_tags($_POST['rating']);

$songres = $wpdb->get_row("SELECT * FROM $table WHERE `title`='$song_title'") or die(mysql_error());
$song_id = $songres->id;
$total_votes = $songres->total_votes;
$total_votes = $total_votes+1;

$ip = $_SERVER['REMOTE_ADDR'];


$data = array(
    'song_id' => $song_id,
    'rating_value' => $rating_value,
    'user_ip' => $ip
);


$check = $wpdb->get_results("SELECT * FROM $table1 WHERE song_id='$song_id' AND user_ip='$ip'");
if(!$check){

$insert = $wpdb->insert($table1,$data);


$wpdb->update( 
    $table, 
    array(
        'total_votes' => $total_votes,
    ), 
    array( 'ID' => $song_id ) 

) or die(mysql_error());
echo 'Thank you';
}else{echo 'Already rated';}    

die();

}

index.php

add_action('wp_ajax_my_special_ajax_call5', 'implement_ajax5');
add_action('wp_ajax_nopriv_my_special_ajax_call5', 'implement_ajax5');//for users that are not logged in.

I dont understand what happen when i alert it shows me right values but not add or update in database.

ok just try this in your Ajax.js at top of the page

var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";

And every thing goes perfect

and i think in your process page there is no need to update query. If you want to delete this there is no issue.
