How to save an option in a dropdown menu as a php session variable? -


i trying save 1 of options in dropdown menu session variable.

<select name="number" id="number">             <option>one</option>             <option>two</option>             <option>three</option>         </select>              <?php          session_start(); $_session['number'] = $_post['number']; ?>

what returns in browser page is:

notice: undefined index: number in c:\xampp-portable\htdocs\eva\00ideaselection.php on line 46

  1. what error here?
  2. what best way save option dropdown menu session variable?

try 

<select name="number" id="number">         <option>one</option>         <option>two</option>         <option>three</option>     </select>     <?php      session_start();      if(isset($_post['number']))          $_session['number'] = $_post['number'];   ?>

the error see because have not posted form , trying value $_post. $_post , $_get has data posted form. when posting form same php script form created, when form loaded without form post, show notice message. avoid notice message, place 

   isset($_post['number'])

check, way no notice shown.

when form posted, , $_post, value set session.

thanks
