Send data via cURL without reloading page
In a facebook iframe page (not tab), I'd like to post data to an external API using cURL, but I would prefer if my form page didn't reload.
I'd like to have some jquery ajax happening ("submitting data" message on submission of the form and a success message on success of the curl_exec). I was thinking of creating a hidden iframe with a duplicate form and update values in that form on change events, but i don't know quite how I'd implement that exchange between PHP and jquery.
Is there a better way? Here's the code I'm working on:
UPDATED CODE TO RETURN FALSE -- Does not submit form data.

Curren开发者_如何学Pythontly this will successfully send the data to the external PHP API, but the iframe (or my whole file) reloads on submission (and displays "success" message).
What you want to do is issue an AJAX Post request on the submit event of your form. The success callback of that AJAX Post request should update your UI to alert the user that their post was sucessful.
$('#signoff').submit(
//Ajax post request here
//http://api.jquery.com/jQuery.post/
return false; //this stops your page from refreshing
);
Have you looked at http://api.jquery.com/jQuery.ajax/ or http://api.jquery.com/jQuery.post/
The following code should help you get started.
$.ajax({
type: 'POST',
url: url,
data: data,
success: success
dataType: dataType
});
Where
url is a string containing the URL to which the request is sent.
data is a map or string that is sent to the server with the request.
success is a callback function that is executed if the request succeeds. It should take three arguments: (data, textStatus, XMLHttpRequest)
dataType is the type of data expected from the server.
