I am using WP Post Views plugin to display the post number of views. To do so, I use:

<?php if(function_exists('the_views')) { the_views(); } ?>

The problem is: The plugin increments the number of a post views if the user just refreshes the post page. It will be good if the number of views increase only one time for a specific user.

I thank you for your time.Your usual help is always appreciated.

The link to the code source is :http://plugins.trac.wordpress.org/browser/wp-postviews/trunk/wp-postviews.php


I already managed, with the help of SE community, to exclude the views by post author using the following hack:

function remove_view_counter_wpse_102637() {
  global $post;
  $current_user = wp_get_current_user();

  if (
    && !empty($current_user)
    && $post->post_author == $current_user->ID
  ) {
    remove_action('wp_head', 'process_postviews');
add_action('wp_head', 'remove_view_counter_wpse_102637',1);

But I cannot manage to exclude the multiple counts by same user using the same logic.

Since the plugin author does not offer any actions or filters for us to hook onto, we'll have to settle for "listening" to changes to the views meta field instead.

function wpse_104324_prevent_multiple_views( $meta_id, $object_id, $meta_key, $meta_value ) {
    if ( $meta_key === 'views' ) {
        if ( ! empty( $_COOKIE[ USER_COOKIE . '_views' ] ) )
            $viewed = array_map( 'intval', explode( ',', $_COOKIE[ USER_COOKIE . '_views' ] ) );
            $viewed = array();

        $viewed[] = $object_id;
            USER_COOKIE . '_views',
                ',', $viewed
            time() + 31536000,

add_action( 'updated_post_meta', 'wpse_104324_prevent_multiple_views', 10, 4 );
add_action( 'added_post_meta',   'wpse_104324_prevent_multiple_views', 10, 4 );

What happens now, is that whenever views is modified, we add the current post ID to the current user's "view stack", then save it as a cookie.

With this in place, we can now check to see if a user has already viewed the post, and if so, prevent their view count from being saved again.

if ( ! empty( $_COOKIE[ USER_COOKIE . '_views' ] ) ) {
    $viewed = array_map( 'intval', explode( ',', $_COOKIE[ USER_COOKIE . '_views' ] ) );
    if ( in_array( $post->ID, $viewed ) )
        remove_action( 'wp_head', 'process_postviews' );

Put this last code snippet inside the remove_view_counter_wpse_102637 function.

I thank you very much. I read the codes you provided and I clearly see that the logic behind will surely resolve my problem. I will implement this and come back to accept. –  whiteletters and blankspaces Jun 26 '13 at 16:25
this is working perfectly, I am really thanking you for the solution and for the cookies science I learned from it. Good luck in your projects. –  whiteletters and blankspaces Jun 26 '13 at 17:00
How can I solve the "Cannot modify header information - headers already sent by " warning caused by your suggested code. Thank you –  whiteletters and blankspaces Oct 24 '13 at 18:17
