<button type="button" onclick="location.href = '<?php echo base_url(); ?>/index.php/Orders/'" class="btn btn-primary btn-md">Back </button>
</div>

Answer 1

You can use GET method to achieve this result

<form method="get" action="<?php echo base_url(); ?>/index.php/Orders/'">
<input type="text" id=first name="first">
<input type="text" id=second name="second">
<select id=oid>
     <option></option>
</select>

<div class="col-md-4">
<button type="submit" class="btn btn-primary btn-md">Back </button>
</div>

Your URL will be like this

http://somedomain.com/index.php/Orders/?first=john&second=Doe

Edit

But when you want to keep the post values for sometime in the application even you moving around to other pages, you may think of session in PHP

In Codeignite way, it will be as follows

$this->session->set_userdata('first', $_POST['first']);

To get this value

$this->session->userdata('first');

Sample input element in your case

$first = $this->session->userdata('first');
<input type="text" id=first name="first" value="<?php echo $first?>">
