Javascript innerHTML with session PHP from other page

Question

I have 2 page

the innerhtml onclick page (a.php)
the page that start session (b.php)

in a.php I write function onclick to change some text and I add the session from b.php in this text, but nothing change in text

 $(document).ready(function(){       
      $('.add-to-cart').on('click',function(){

        document.getElementById('outside_cart_text').innerHTML = 
"Qty type <?php echo $this->session->userdata('qty_type'); ?> amount <?php echo $this->session->userdata('qty_product');?>";

            });
        });

it change the original text to "Qty type amount". But session value not appear.

the question is how to make it appear instantly?

additional detail : My click is on the button sumbit to other page, but I have already use this trick. It work like ajax. so after click I still in the same page (and not reload)

<style>
  .hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>

<iframe name="hiddenFrame" class="hide"></iframe>

<form action="receiver.pl" method="post" target="hiddenFrame">
  <input name="signed" type="checkbox">
  <input value="Save" type="submit">
</form>

b.php page session->set_userdata('qty_type', sizeof($this->cart->contents())); $this->session->set_userdata('qty_product', $this->cart->total_items()); ?> — Supanat T. Boss, Oct 25 '16 at 04:46
the button in a.php will submit to b.php page and the update qty's logic is in the b.php page too. — Supanat T. Boss, Oct 25 '16 at 05:17
Can you try var_dump($_SESSION); outside the js code of a.php and paste it here? — krasipenkov, Oct 25 '16 at 05:24
If you are using `codeigniter`,you using `controller` to declare `session variables`? — Hiranya Sarma, Oct 25 '16 at 06:47

Maybe it would work if the variables are encoded in json format.

document.getElementById('outside_cart_text').innerHTML = 
  "Qty type
  <?php echo json_encode($this->session->userdata('qty_type')); ?> 
  amount 
  <?php echo json_encode($this->session->userdata('qty_product'));?>";
});

$(document).ready(function(){       
    $('.add-to-cart').on('click',function(){
        var qty_type = '<?php echo $this->session->userdata('qty_type'); ?>';
        var amount = '<?php echo $this->session->userdata('qty_product'); ?>';
        $("#outside_cart_text").html("Qty type "+qty_type+" amount "+amount);
    });
});

sorry session value don't come – Supanat T. Boss Oct 25 '16 at 05:15
you would have to call session value using ajax from b.php and then add into html – Bhavik Oct 25 '16 at 05:20
