hello world,
i am new to wordpress plugin development. below functions are located in my plugin folder. the issue is that i am unable to get session data on theme pages. however, the session are being set, but the data is not displayed at frontend. when i refresh the page the data is displayed. what could be the reason? please help. Thank You

i tried fixing with this but it didnt work.

function register_session()
{ 
	if( !session_id() )
	{ 
		session_start(); 
	} 
} 
add_action('init', 'register_session');

function setSession($sessionKeys = array(),$value = NULL) {
   if(isset($sessionKeys[0]) && isset($sessionKeys[1])) {
        $_SESSION['main_entry'][$sessionKeys[0]][$sessionKeys[1]] = $value;
    } else if(isset($sessionKeys[0])){
        $_SESSION['main_entry'][$sessionKeys[0]] = $value;
    } else {
      return false;
    }
    session_write_close();
    sleep(1);
    write_log($_SESSION['main_entry'], 'MAIN ENTRY');
}

function getSession($sessionKeys = array(), $default = NULL) {
 if(isset($sessionKeys[0]) && isset($sessionKeys[1])) {
      return isset($_SESSION['main_entry'][$sessionKeys[0]][$sessionKeys[1]]) ? $_SESSION['main_entry'][$sessionKeys[0]][$sessionKeys[1]] : $default;
  } else if(isset($sessionKeys[0])) {
      return isset($_SESSION['main_entry'][$sessionKeys[0]]) ? $_SESSION['main_entry'][$sessionKeys[0]] : $default;
  } else {
      return $_SESSION['main_entry'];
  }
}

//unable to get session data on view pages.. even if session data is being set
getSession(array('order'));

I’m not able to look up resources right now but you might want to check out wordpress.org and sessions. I seem to remember running into a problem a few years ago and finding out that WordPress is stateless and it is not straightforward getting sessions to work.
