PHP-General - Need help in PHP Curl and Ajax

Hi All,

We 've 20 promotional websites and we want to centralize the contact us form.
We have contact us form that is kept in Server 2 and all the other web sites kept in server 1, now i need to include the contactus form server1 inside server 2 websites.
For this i am using PHP Curl function to include the cross domain file (contact us Form).
Now the problem is when i submit the form i want to call a ajax function to save the details in DB and to send mails, but ajax function is not getting triggred in the form.

I want to know if we can call the ajax function on submmit? or are there any other method to call file (or Include a file) from different SERVER(or domain) than using CURL?

Thanks and Regards,
Deepak
