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

    I am trying to save one of the options in a dropdown menu as a session variable.
    Code:
    <select name="number" id="number">
            <option>one</option>
            <option>two</option>
            <option>three</option>
        </select>

            <?php
         session_start();
$_SESSION['number'] = $_POST['number'];
?>
    What it returns in the browser page is:

    Notice: Undefined index: number in C:\xampp-portable\htdocs \eva\00ideasele ction.php on line 46
    What is the error here?
    What is the best way to save an option from a dropdown menu as session variable?

      I would suggest building a method in the header of the page that takes in a parameter of the value you want to set, then set the cookie or session. That is to say:

      Code:
      <html>
  <head>
    ....
    ....
    <?php 
     function set_session($value){
      setcookie("Option",$value);
     }
    ?>
  </head>
  <body>
    /// put form data here

   <?php
     if(islet($_POST['submit'])){
      set_session($_POST['number']);
     }
    ?>
   </body>
</html>
      I am also posting a link to a great resource I recommend you look over:
      PSR-1: Basic Coding Standard - PHP-FIG
      http://www.php-fig.org/psr/psr-1/
      We're a group of established PHP projects whose goal is to talk about commonalities between our projects and find ways we can work better together.


      Hope that helps!
