How to show the number of each post has been read in a while loop?

Question

I have this code in my header.php and it is working:

<div id="news">
        <?php query_posts('category_name=news'); ?>
        <?php while (have_posts()) : the_post(); ?>
            <div class="new">
                <a href="<?php the_permalink(); ?>">
                <?php the_post_thumbnail('thumbnail'); ?>
                </a>
                <a href="<?php the_permalink(); ?>">
                    <h3><?php the_title(); ?></h3>
                </a>
                <?php the_excerpt(); ?>
                <p>
                    <span class="autor">Author: <?php the_author(); ?></span>&nbsp;|&nbsp;
                    <span class="autor">Date: <?php the_date(); ?></span>&nbsp;|&nbsp;

                </p>

            </div>

        <?php endwhile; ?>
</div>

Now, I would like to do something like:

<span class="views">Views: <?php the_views(); ?></span>&nbsp;|&nbsp;

to show each post how many times was read. However, it is throwing an error. How to solve this?

Answer 1

the_views() is not a built in function of WordPress. In fact, WordPress does not, by default, log the number of views of posts.

There are probably several plug-ins that exist which add this functionality. The only one I have ever used (and its one I've never had any problems with) is WP-Postviews http://wordpress.org/extend/plugins/wp-postviews/.

Answer 2

in function.php put this code

function getPostViews($postID){
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '0');
    return "0 View";
}
return $count.' Views';}
function setPostViews($postID) {
$count_key = 'post_views_count';
$count = get_post_meta($postID, $count_key, true);
if($count==''){
    $count = 0;
    delete_post_meta($postID, $count_key);
    add_post_meta($postID, $count_key, '0');
}else{
    $count++;
    update_post_meta($postID, $count_key, $count);
}}

then in single.php put this code <?php setPostViews(get_the_ID()); ?>

to show views count put this code anywhere you want <span class="views"><?php echo getPostViews(get_the_ID()); ?></span>&nbsp;|&nbsp; that will count each visit to the post you can put it in the loop.php/index.php to view each post views
