And the code calling the insert on the index page is below:
Code:
elseif(isset($_POST['button']) && $_POST['button'] == 'Submit JC')
{
  	
  $results = array();
  $data = new JobCardManager();
  $data->storeFormValues( $_POST );
  $data->insertJobCard();
  
	  $output = "Information successfully added to the database";
	  include 'output.html.php';
      exit();
