Answer 1

use readonly instead of disable...

deference between readonly and disable click here.

if u r using readonly u hve to specify value and give button

in view

<form action="<?php echo base_url('action/getpost'); ?>" method="post">
<div class="row marketing">
   <div class="col-lg-6">
   <div class="form-group">
       <input  value="firstname" readonly required type="text" class="form-control" name="firstname" id="firstname_field" placeholder="First name">
   </div>
   <div class="form-group">
        <input  value="lastname" readonly required type="text" class="form-control" name="lastname" id="lastname_field" placeholder="last Name">
    </div>
    <div class="form-group">
        <input  value="" readonly required type="text" class="form-control" name="cardholderid" id="cardholderid_field" placeholder="Cardholder ID">
    </div>
  <div class="form-group">
      <input  value="cardnumber" readonly required type="text" class="form-control" name="cardnumber" id="cardnumber_field" placeholder="Card Number">
   </div>
  <div class="form-group">
        <button type="submit">Submit</button>
  </div>
</div
</form>

in controller

function getpost()
{
  print_r($this->input->post());
}
