   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.
