How i generate the Week, Month and Year view statistics widget for this site. 

Views Widget Function

This generates the widget based on the views data.

PHP

// views widget
  /*
  using fields_array for incoming variables
  this->fields_array = array(); // reset the array each time.
  this->fields_array["linked_class"] = $linked_class;
  this->fields_array["linked_uid"] = $linked_uid;
  generates a widget showing hits today, this week, month and year.
  will need multiple functions to calculate these, maybe break it up and reuse them.
  */
  public function views_widget($linked_class,$linked_uid) {

    // views this week
    $this->fields_array = array(); // reset the array each time.
    $this->fields_array["linked_class"] = $linked_class;
    $this->fields_array["linked_uid"] = $linked_uid;
    // $this->fields_array["week_num"] = $week_num; or
    $this->fields_array["week_num"] = date("W");

    $views_week_single = $this->views_week_single();

    $views_widget_template = new template("views-widget-table.html");

    $views_widget_template->set("views_week_single", $views_week_single);

    // get the monthly views
    $this->fields_array["month_num"] = date('m');
    $views_month_single = $this->views_month_single();
    $views_widget_template->set("views_month_single", $views_month_single);

    // get the yearly views
    $this->fields_array["year_num"] = date('y');
    $views_year_single = $this->views_year_single();
    $views_widget_template->set("views_year_single", $views_year_single);

    return $views_widget_template->output();


  }

Widget Template File

This is the html template used for the widget layout. 

PHP

<style>
  .view-title {
      text-transform: uppercase;
      font-weight: bold;
      font-size: 12px;
      color: #62b174;
      margin-bottom: 5px;
      padding-bottom: 5px;
      border-bottom: 1px solid #3a3a3a;
  }
  .view-number {
      text-transform: uppercase;
      font-weight: bold;
      font-size: 32px;
      color: #FFF;
  }
</style>
<div class='card mb-3 view-stats'>
  <h5 class='card-header'>View Statistics</h5>
  <div class='card-body'>
    <div class='row'>
        <div class='col col-lg-4'>
          <div class='view-title'>
            This Week
          </div>
          <div class='view-number'>
            [@views_week_single]
          </div>
        </div>
        <div class='col col-lg-4'>
          <div class='view-title'>
            This Month
          </div>
          <div class='view-number'>
            [@views_month_single]
          </div>
        </div>
        <div class='col col-lg-4'>
          <div class='view-title'>
            This Year
          </div>
          <div class='view-number'>
            [@views_year_single]
          </div>
        </div>
    </div>
  </div>
</div>

Adding the widget to the page content

Add the widget to page content, this is the last bit. 

PHP

// generate a views widget
	$page_content .= $views_class->views_widget($linked_class = $p2,$linked_uid = $p3);
