In all Entertainment sites, Star rating is a common phenomena. We need to use star rating for rating different resources like videos, articles, thesis, posts even sometimes persons. JQuery has an excellent Star Rating plugin, which I recently use with PHP CodeIgniter. This is very simple to integrate with controller and show high quality rating options.
Jquery Call:
$(function() {
$('.auto-submit-star').rating({
required: true,
callback: function(value, link) {
$.ajax({
type: "post",
url: site_url + "user/view/star",
dataType: "json",
data: "&video=" + $('#video_url').val() + "&rate_val=" + value,
success: function(e) {
$.jGrowl(e.code + "<br>" + e.msg);
}
});
}
});
Controller Method:
public function star()
{
$rate = $this->input->post("rate_val", true);
$video_url = $this->input->post("video", true);
$this->load->model("Model Name");
$video_id = $this->model_name->get_video_id($video_url);
unset($this->layout); //Block template Layout
if (get_user_id()) //get_user_id() return login user id
{
if (!$this->model_name->is_video_rated(get_user_id(), $video_id))
{
$data = array("video_id" => $video_id,
"user_id" => get_user_id(),
"videos_rating_value" => $rate,
"videos_rating_date" => "" . date("Y-m-d H:i:s") . ""
);
if ($this->model_name->insert_rating($data, $video_id, $rate))
{
echo json_encode(array("code" => "Success", "msg" => "Your Video Rating has been posted"));
}
else
{
echo json_encode(array("code" => "Error", "msg" => "There was a problem rating your video"));
}
}
else
{
echo json_encode(array("code" => "Error", "msg" => "You have already rated this video"));
}
}
else
{
echo json_encode(array("code" => "Error", "msg" => "You have to login to rate the video"));
}
exit(0);
}
Presentation View:
if (!get_user_id()) //Check if user logged in
{
$radio_level = "disabled";
}
else
{
$radio_level = " ";
}
for($i = 1;$i <= 5;$i++)
{
if ($i == round($row["total_rate"]))
{
?>
<input class="auto-submit-star" type="radio" name="rating" <?php echo "$radio_level";
?> value="<?php echo $i;
?>" checked="checked"/>
<?php
}
else
{
?>
<input class="auto-submit-star" type="radio" name="rating" <?php echo "$radio_level";
?> value="<?php echo $i;
?>"/>
<?php
}
} //end of for
?>
Its a very cool 
rating JQuery plugins.
