Session not save after redirect in WordPress

Question

I have created a template page in WordPress. I want save the value in the session by opening the template page link, but I do not get that value after being redirected to product page. So what am I doing wrong?

I'm trying in the code below.

This is template file where i set session!

<?php
/**
* Template Name: HDFC Coupon
*/

$coupon_code = 'HDFC10EGMKKRYD';
$coupon = new WC_Coupon($coupon_code);
$product_ids = $coupon->get_product_ids();

$_SESSION['HDFC_COUPON_VALID'] = true;

if(count($product_ids) == 1){
    $url = get_permalink(reset($product_ids));
}else{
    $url = wc_get_cart_url();
}
wp_redirect($url);
exit();

This is function.php code where i want to get session value, but i got black array of session!

<?php
session_start();

add_filter('woocommerce_get_price', 'woocommerce_get_price_fun', 10, 2);
function woocommerce_get_price_fun($price, $product){

    // here it's blank when i print this : print_r($_SESSION)

    if(is_product() && isset($_SESSION['HDFC_COUPON_VALID']) && $_SESSION['HDFC_COUPON_VALID']){
        // sonthing which i want to do after session value get.
    }
    return $price;
}

it's working fine when i comment this line wp_redirect($url);, but when i use redirect then it not save data in session.

@FunkFortyNiner i already read those question, It is not appropriate for you to close the question without understanding it. because my question is, it's already working if i comment redirect line. but when i use redirect then it not save data in session. — Bhavik Hirani, Jul 04 '20 at 15:44
@FunkFortyNiner But I do not understand your question, what you asking ? — Bhavik Hirani, Jul 04 '20 at 16:04
Consult the following: https://www.php.net/manual/en/function.error-reporting.php and put that in all your php files. — Funk Forty Niner, Jul 04 '20 at 16:04
it's already enabled, `error_reporting(E_ALL); ini_set('display_errors','on');` but it nothing display as error — Bhavik Hirani, Jul 04 '20 at 16:08
I've reopened the question. Let's see if someone else can find what the cause could be. — Funk Forty Niner, Jul 04 '20 at 16:13

WooCommerce has it's own session handler, which you can use by calling WC()->session. https://docs.woocommerce.com/wc-apidocs/class-WC_Session_Handler.html

It's possible that this is conflicting with session writes if you're using the $_SESSION superglobal, particularly if you're calling exit before the session has been written.

Instead, try using

WC()->session->set('HDFC_COUPON_VALID', true);

and

WC()->session->get('HDFC_COUPON_VALID');

followed by

WC()->session->save_data();

sorry, i missed your reply! Updated my answer - try adding `WC()->session->save_data();` before you redirect. – benJ Jul 16 '20 at 14:29
