Parse data before sending it to action link or artificial POST request

Question

I have a form and it have action="http://anotherhost.com" . But I have a problem, before sending it to another host I need to save entered data to database and here is a problem, how to do it?

I have idea, but don't know how to realise it.
1) Change action="http://anotherhost.com" to my site, parse entered data and add into database, but then after this I need to simulate artificial POST request to another host.
2) First parse it with JS (AJAX) and after parsing it, let to send form to another host.

Answer 1

Your second option is probably the best way to go, something like this should work!

http://jsfiddle.net/7Sq3J/

$('form').submit(function(event) {
    $.post('http://example.net/', $('form').serialize(), function(data){
        // handle returned data in here
    });
});

This will use a POST request, and send everything you send in the form to http://example.net/
