1. Detecting Bottom of the pageAJAX 请求使用WP AJAX (tutorial) 保存该数据

您可能希望将“read\\u whole\\u post”存储为Posteta值。大致如下：

add_action( \'wp_ajax_read_whole_post\', \'se200479_read_whole_post\' );
add_action( \'wp_ajax_nopriv_read_whole_post\', \'se200479_read_whole_post\' );

function se200479_read_whole_post() {
    // Passed through jQueryAjax in the settings.data argument
    $post_id = filter_input( INPUT_POST, \'post_id\' );

    // Will return the existing count - ie 0
    $current_count = absint(get_post_meta( $post_id, \'read_whole_post\', true ));

    // increment your count
    $current_count++;

    // Update the database value
    update_post_meta( $post_id, \'read_whole_post\', $current_count );

    // Terminate the AJAX request
    wp_send_json_success();
}

您还需要考虑在JS中的页面上存储一些内容，比如updated = true 确保如果有人在页面上下滚动一堆，您不会多次增加您的计数值！
