    Session Variable Help

    I am trying to move data from one page to another using $_SESSION, without putting the information on a database.

    This is what I have. My issue is when I have $_SESSION['first_name']='john' it passes the $_SESSION to the next page but when I have the $_POST in it will not pass the information that is put in the input. Why is it doing this? Also my register_global s is turned to off.

    Thanks in advance.
    Code:
    <?php
session_start();
$_SESSION['first_name'] = $_POST['first_nameID'];
?>

      Hey there
      The "name" part of a form input is the Name thats passed when you submit the form, so try changing that to "first_name ID".
      Also, just to make sure its getting there, try changing your first line of code to:
      Code:
      if (isset($_POST['first_nameID']) {
  //this checks to make sure that the POST variable is set
  if (ctype_alnum($_POST['first_nameID'])) {
    //this makes sure that first_nameID is only made of charectesr 
    //and numbers
    $_SESSION['first_nameID'] = $_POST['first_nameID'];
  } else {
    $_SESSION['first_nameID'] = false;
  }
} else {
  $_SESSION['first_nameID'] = false;
}
      This will just make sure that people dont submit malicious data though your form.
      Hope that sorts it out.

          Well I tried it and it still did not work. The form is not passing it to the variable. What would cause this?
