Topic: Making WP-PostRatings 1.50 Work With SuperCache Properly

[lokos]

Hi, Here is how you can make wp-postrating to always show the updated rating with supercache installed

The problem you describe above happen because when you vote your rating refresh via AJAX so you see the updated view count immediately but once the page is refreshed supercache show the cache page with the old rating.
The solution: Load the rating with AJAX

1. Add the AJAX function to get the rating into your theme's function.php file

Code: [Select]

function get_rating_ajax($id) {
$nonce = wp_create_nonce('my_rating');
?>

<div id="ratings-wrap-<?php echo $id;?>">
<img src="/wp-content/uploads/images/loading_rating.gif" />
</div>

<script type="text/javascript">
jQuery(document).ready(function($){
  $.ajax({
    type : "GET",
    url : "<?php echo get_option('home'); ?>/wp-content/plugins/wp-postratings/wp-postratings.php",
    data : { wp_ajaxaction : "jquery", post_id : <?php echo $id; ?> , _ajax_check : "<?php echo $nonce;?>"},
    success : function(response){$("#ratings-wrap-<?php echo $id; ?>").html(response);}
  });
});
</script><?php
}
?>

2. Add the function to return the rating via ajax on the wp-postrating.php file
Look for the line:

Code: [Select]

$wpdb->ratings = $wpdb->prefix.'ratings';and copy this code below it:

Code: [Select]

if ( $_GET['wp_ajaxaction'] == 'jquery' ) {

$nonce =$_REQUEST['_ajax_check'];
if (! wp_verify_nonce($nonce, 'my_rating') ) die('Security check');

$id = $wpdb->escape($_GET['post_id']);
the_ratings('div',$id);
    exit();
}
3. Use it.

Replace your normal <?php the_rating() ?> function in your theme for  <?php get_rating_ajax ($post->ID) ?>

Make sure jquery is on the page where you are using this.
You can update this <img src="/wp-content/uploads/images/loading_rating.gif" /> for the path of the loading image you want to show while the rating is being updated.

thanks, stickied.

In which file and where shall I put the codes into?

Thanks.

[GaMerZ]

Read the first post carefully, it is all stated there.

Modified the post to make it more obvious

[Need_Help]

Thanks for making it clearer. At first, he just stated function.php (which I couldn't find in the plugin folder)

Thanks.

[Need_Help]

<div id="ratings-wrap-<?php echo $id;?>">
<img src="/wp-content/uploads/images/loading_rating.gif" />
</div>

If you want your site to be XHTML valid, the line in bold should include the alt="" tag, like :
<img src="/wp-content/uploads/images/loading_rating.gif" alt="Loading"/>

Thanks.

PS : Of course, you may put whatever you want between the " mark, or even leave it blank.

Hi!

I just tried your fix. But I got this error message:

arning: Cannot modify header information - headers already sent by (output started at .../functions.php:276) in .../wp-content/plugins/wp-postratings/wp-postratings.php on line 580

Warning: Cannot modify header information - headers already sent by (output started at .../functions.php:276) in .../wp-content/plugins/wp-postratings/wp-postratings.php on line 624

Any idea what I'm doing wrong?

Thank you!

regards,
Japhy

Ensure that you do not have any white spaces after the

Code: [Select]

?>

not work for me :s

in post

"Fatal error: Call to undefined function get_ip_address()"

[GaMerZ]

Your error pasted has nothing to do with this. get_ip_address is not used. It is get_ipaddress() and not get_ip_address();

[eilrax]

sorry xd

Fatal error: Call to undefined function get_ipaddress() in /home/admin/domains/.../public_html/wp-content/plugins/wp-postratings/wp-postratings.php on line 310

[GaMerZ]

I am guessing you did not place the code properly. get_ipaddress() is defined on line 416. Re-download wp-postratings and try again or you can drop lokos an email or private message to send you the modified file.

Thanks for the code, it works great for me just like magic.

But there is a problem for rating that use embed other post ratings such as using [ratings id="1"] or [ratings id="1" results="true"].
The ratings still don't show real time result. It shows cached result instead.

It would be great and helpful, if you can make this work as well.

Hi GaMerZ and Everyone,

Any ideas about the problem for rating that use embed other post ratings such as using [ratings id="1"] or [ratings id="1" results="true"]. with SuperCache enable.
The ratings still don't show real time result. It shows cached result instead.

It would be great and helpful, if you can make this work as well.

Thanks!

I am not using SuperCache but I am guessing that the shortcode will not work with it. because the shortcode will be translated to normal ratings when the supercache parse it, it will be cache. And also by embedding other ratings ID into the post containing ratings will screw up the ID making it not work as well.
