Grab $_GET url parameter from an iframe - WORDPRESS

Question

I’m having a hard time, inside my website I put a iframe that has a button that directs to another page inside my site via GET.

only that this button is already gone.

ex.:

The link inside the iframe goes to http://www.meusite.com.br/Detalhes.php?id=17936

I think I have to create a page with the same name Details and within it put the function $_GET['id'];

I even used a plugin that reads php, and nothing..

I put an iframe inside my site from another server follows the website http://www.grupodisnave.com.br/seminovos/ and when I click on more details the link goes to another page with the id in the URL only wordpress does not allow me to use the GET

Does anyone have any idea what should be done?

Answer 1

You should "cheat" wordpress, since by passing parameters by url you get the error 404 Not Found. Create this simple plugin in your functions.php:

<?php

add_filter('query_vars', 'parameter_queryvars' );
function parameter_queryvars( $qvars )
{
$qvars[] = 'id';
return $qvars;
}
?>

HERE IS THE CONDITIONAL TO OBTAIN THE ID VALUE

global $wp_query;
if (isset($wp_query->query_vars['id'])){
print $wp_query->query_vars['id'];
