}

so please help me..how I get this data in wordpress and most important how do I store them in wordpress session. does normal $_POST works in wordpress????

Answer 1

Yes, $_POST[] works in wordpress. To set session add session_start() at the beginnning of file ie after <?php line. Then set session variable by - $_SESSION['variable_name'] = "variable value"; ex: $_SESSION['my_num'] = 5;

Here session variable my_num is set to 5. To access this variable use

echo $_SESSION['my_num'];
