i want function for post visit on each viewand also show count views in post by idin wordpress i want to set post view data with update_post_meta

To track post views and display the view count in WordPress, you can use the following code:

1. Add the following code to your theme's functions.php file:

function set_post_views($postID) {
    $countKey = 'post_views_count';
    $count = get_post_meta($postID, $countKey, true);
    if ($count == '') {
        $count = 0;
        delete_post_meta($postID, $countKey);
        add_post_meta($postID, $countKey, '0');
    } else {
        $count++;
        update_post_meta($postID, $countKey, $count);
    }
}

// Add the post view increment function to the WordPress 'wp' action hook
add_action('wp', 'track_post_views');

function track_post_views() {
    if (is_single()) {
        set_post_views(get_the_ID());
    }
}

function get_post_views($postID) {
    $countKey = 'post_views_count';
    $count = get_post_meta($postID, $countKey, true);
    if ($count == '') {
        delete_post_meta($postID, $countKey);
        add_post_meta($postID, $countKey, '0');
        return "0";
    }
    return $count;
}

2. To display the view count in your post template, use the get_post_views() function:

<?php echo get_post_views(get_the_ID()); ?> Views

This code will increment the view count whenever a post is visited, and you can display the count using the get_post_views() function by passing the post ID as a parameter
