How can I get the myvar from URL? I tried a lot of examples on the web, but no one works for the category page.

  1. Solved using this code.

    add_filter( 'category_link','append_parameter', 10, 2 );

function append_parameter( $link, $my_parameter ) {
$my_parameter = $_GET['sort']; //get sort value       
if ( isset($my_parameter) ) { 
    $link = add_query_arg( 'sort', $my_parameter, $link );
}
    return $link;
}

  2. You could use this:

    <?php
$myvar = $_GET['myvar'];
?>

    and to make sure, u could also put this code in any page to test it:

    <?php
echo $myvar;
?>

    This is simply the $GET[] function in PHP.
