<?php
/*
For a simple way to keep track of the number of post views, paste this snippet into the functions.php, and then follow steps 1 and 2.

function getPostViews($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');
        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);
    }
}

/*
Step 1: Paste the code below within the single.php within the loop:

    setPostViews(get_the_ID());

Step 2: Paste the snippet below anywhere within the template where you would like to display the number of views:

    echo getPostViews(get_the_ID());
*/

Shouldn't $count start at 1? Since the first time it is called it will be the post being viewed once.
