I am trying to intercept the GET request of a post and add a value to it.

function foo($request) {
    $request['vid'] = wp_generate_uuid4();

    return $request;
}
add_filter( 'request', 'foo' );

and hope that it would be available later with

$_REQUEST['vid']

but no access so far any ideas?

  • WordPress doesn't add vid to the $_REQUEST array. Use get_query_var( 'vid' ) to access the vid value.. – Sally CJ Commented May 15, 2019 at 13:10

WordPress doesn't add the vid to the $_REQUEST array. Instead, it's saved in a class property — see WP::$query_vars which is an array.

And to access the value of items in that array, use get_query_var() like so in your case:

$vid = get_query_var( 'vid' );
echo "vid value is $vid";
