timeline class and function

this is a class extend that generates a timeline based on structured data and order's the items by year decending.

this code will not work out of the box as it has other requirements, but it is a good example or starting point for a similar function to generate a timeline

also it had a requirement where the colours had to change per row so i added another array of the required colours and assigned each colour to the css that is generated as part of this function. 


// timeline.extend.php
class timeline extends core {

  public $class_extend = true; // this must be set to true! :)

  public $add_to_menu = false;
  public $add_section_button = false; // add this class to the section menu
  public $add_to_admin_menu = true; // add this class to the main admin menu

  public $nice_name = "timeline";
  public $nice_description = "timeline";
	public $db_table_name = "timeline";
  public $images_enabled = true;

  public $load_array = [

  public function show_timeline() {
    $db_table_name = $this->db->escapeString($this->db_table_name);
    $sql = "select * from $db_table_name order by year desc";
    $out = "";
    $css = "";
    $color_array = array(

    $result = $this->db->query($sql);
    $line_num = 1;
    $col_array_num = 0;
    if($result) {
        while($row = $result->fetchArray()) {
            // $out .= $row['field_name'];
            foreach($this->load_array as $load_title) {
                //$template->set($load_title, $row[$load_title]);
                $this->$load_title = $row[$load_title];

            $out .= "<div class='timeline-item timeline-item-$line_num'>
  <div class='grid-x'>
    <div class='large-1 cell'>
      <div class='timeline-year'>
    <div class='large-1 cell'>
      <div class='timeline-dot'>
    <div class='large-2 cell'>
      <div class='timeline-month'>
    <div class='large-7 cell'>
      <div class='timeline-title'>

            // add color css
            $line_color = $color_array[$col_array_num];
            $css .= ".timeline-item-$line_num { color:$line_color; } .timeline-item-$line_num .timeline-dot { background:$line_color; }";

            if($col_array_num == 7) {
              $col_array_num = 0;


        $out = "<style>$css</style>
        <div class='timeline-wrap'>
        return $out;
    } else {
        return false;


// view page timeline
// where $page_content is the page output
$page_content .= '
/* Timeline */
.timeline-item {
