Rating not add with ajax in wordpress - php

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.

Answer 1

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.

Answer 2

i get this a lot........ajaxurl needs to be defined, so i've learned that its just easier to not use ajaxurl and put in "/wp-admin/admin-ajax.php" in the url section.
Also i dont see you using non-conflict jQuery? (use the word jQuery instead of $)
You may also have issues with your postdata string, i may be wrong but what you need is action: '' ,
rating: '',
etc.
A good practice is to var_dump $_POST and exit at the beginning of your function to make sure they are passing over correctly. then in success- console.log(res) or whatever you are calling your return data
function bindEvents() {
jQuery(cssSelector.rating_succes).css('display','none');
//Set the new rating when the user clicks
jQuery(cssSelector.ratingLevel).click(function() {
var $this = jQuery(this), rating = $this.parent().children().index($this) + 1, index;
var trackname = jQuery(cssSelector.title+':first').text();
//alert(postdata1); -> console.log() is better for looking at objects
jQuery.ajax({
type:'POST',
url: "/wp-admin/admin-ajax.php",
cache:false,
data: {
action: 'my_special_ajax_call5',
rating: rating,
trackname: trackname
}
success:function(output){
console.log(output)
jQuery(cssSelector.rating_succes).html(output).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));
});
}
see how you get on with that :)
