<strong>// to this just change the values in search

Sorry Luis, i have a custom page called "Preventivo Hotel"...

Luis Abarca comments:

OK, then change the "if" statement to check if you are in that page.


$page = get_page_by_path('/preventivo-hotel');

if ( !is_page($page->ID) ) {
return false;
}
...

Luis, i have now tested your code:

i've put that on my functions.php http://pastebin.com/4zXPN2nw

and this is the code for the custom form http://pastebin.com/MyL9rYSq

my result in my page test: http://d.pr/CX9

Luis Abarca comments:

You need to add a name to each dropdown in your form


<?php my_dropdown('hotel', 'localita_hotel'); // repeat foreach dropdown ?>
<?php my_dropdown('hotel-category', 'localita_hotel_category'); // use your own taxonomies ?>


http://pastebin.com/LVgthfnt

Then, register the query vars to match your form fields


add_filter('query_vars', 'mycustom_query_vars');

function mycustom_query_vars($query_vars)
{
$query_vars[] = 'hotel';
$query_vars[] = 'hotel-category';
....

return $query_vars;
}
