i use 

<?php                               if(isset($_session['email'])) {                              echo $_session['email'];                          }                         ?>

it works , pulls there email address how there username? tried changing email username , nothing shows

my login setup

/* login functions */   function login_user($email, $password, $remember) {     $sql = "select user_pwd, uid users user_email = '" . escape($email) . "' , active = 1";      $result = query($sql);      if (row_count($result) == 1) {          $row = fetch_array($result);          $db_password = $row['user_pwd'];          if (password_verify($password, $db_password)) {              if ($remember == "on") {                                  setcookie("email", $email, time() + 86400,'/');              }              $_session['email'] = $email;              return true;         } else {              return false;         }          return true;     } else {          return false;     } }   /* user logged in function */   function logged_in(){      if (isset($_session['email']) || isset($_cookie['email'])) {          return true;     } else {          return false;     } }

you need make small changes in login_user() function.

 function login_user($email, $password, $remember) {    $sql = "select user_pwd, uid, username users user_email = '" . escape($email) . "' , active = 1";     $result = query($sql);     if (row_count($result) == 1) {      $row = fetch_array($result);      $db_password = $row['user_pwd'];      if (password_verify($password, $db_password)) {          if ($remember == "on") {                              setcookie("email", $email, time() + 86400,'/');          }          $_session['email'] = $email;         $_session['username'] = $row['username'];          return true;     } else {          return false;     }      return true;   } else {      return false;    } }

now can use below code username in session. make sure must have username field in users table.

if(isset($_session['username'])) {   echo $_session['username']; }
