I'm trying to add some function to each loop called in the themes. What I'm doing is I add a function to count post view from here post views without plugin, to use the function I need to add this line <?php setPostViews(get_the_ID()); ?> to single.php, page.php, etc.

I want to know whether I can use some hook to automatically add the <?php setPostViews(get_the_ID()); ?> line without hard code it for each single.php, page.php files.

You could hook into template_redirect and execute a helper function:

add_action( 'template_redirect', 'wpse_75558_count' );

function wpse_75558_count()
    if ( is_singular() )
        setPostViews( get_the_ID() );

To display the post views, you have to use a later hook. I would recommend the_content:

add_filter( 'the_content', 'wpse_75558_show_count' );

function wpse_75558_show_count( $content )
    $count = getPostViews( get_the_ID() );

    if ( ! is_numeric( $count ) )
        $count = ''; // prevent errors showing to visitors
        $count = "<p class='view-count'>Views: $count</p>";

    return $content . $count;

Just an idea, I haven’t tested the code.

  • Thanks @toscho it works like a charm :D, only there is one problem, when using with setPostViews it works okay, and value get into database, but when use for getPostViews, it show nothing, try to print_r(getPostViews()) still get nothing. Any idea? Dec 10, 2012 at 15:56
  • @nackle template_redirect action happens too early to print something out. I made an update with a second suggestion.

  • thanks this is working great, btw you forgot to close the if statement, oh and I remove the if stamement since it looks like the getPostViews already handle the value to be 0 when there is no meta or post view. Thank you so much this really help me out Dec 10, 2012 at 16:13
