That is because your form does not contain the elements latitude and longitude , whereas the above form what you have defined has those fields , but they are never submitted.

<form action="" method="post">
    <input type="hidden" name= "longitude" id="longitude"> <!-- I have added here-->
    <input type= "hidden" name ="latitude" id="latitude"> <!-- I have added here-->
    <input type="submit" name="ido" value="Click" /></td>
    </form>

It works, but im just testing these codes for my bigger project, which requires those two forms to be seperated from each other – user2897858 Oct 25 '13 at 10:40

If you need the forms to be independent - then you should consider using a custom submit method and submit via ajax. That will give you the opportunity to parse the elements you need and then submit the data.
