 * Hello,
 * In my comments.php I inserted a form :
 *     ```
       <form name="myForm" action="" method="GET" style="float:right" >
       		<SELECT NAME="format">
       <OPTION>Test 1
       <OPTION>Test 2
       </SELECT>
       		<SELECT NAME="ordre">
       <OPTION>Example 1
       <OPTION>Example 2
       </SELECT>
       	<input type="submit" name="submit" value="Trier">
           		</form>
       ```
   
 * I want to store the selected value in a cookie, so I added this function to my
   functions.php :
 * <?php
    function set_navi_cookie() { $sc_ordre = $_REQUEST[‘ordre’]; setcookie(‘
   naviga’,$sc_ordre,time()+60, COOKIEPATH, COOKIE_DOMAIN, false); } add_action(‘
   init’, ‘set_navi_cookie’); ?>
 * but **$sc_ordre is null**. I tried $_REQUEST[‘ordre’]; but it’s always null.
 * What I did wrong ?

 * Does it work if you change the select to:
 *     ```
       <SELECT NAME="ordre">
       <OPTION value="Example 1">Example 1</OPTION>
       <OPTION value="Example 1">Example 2</OPTION>
       </SELECT>
       ?>
       ```

 * Thanks for your help, but no, it doesn’t work. I think that </option> is not 
   needed in this example.
 * I can catch the passing variables in single.php for exemple but not in functions.
   php where I need it.

 * It’s invalid not to have closing tags for options, so yes they are required if
   you want to write valid code.
 * `$sc_ordre` will be null outside the function because it only has scope inside
   the function.
 * About variable scope
