Question

I’m currently trying to get a script to submit a form to a page that is external to my site but will also e-mail the answers given by the customer to me. The mail() function has worked fine for the mail… but how do I then take these values and also submit them to the external page?

Thanks for your help!

Answer 1

If you get the form to submit to your script, can could first send the email and then use cURL to make a HTTP request to the external page, POSTing the values you want to send. This won’t work though if the external site is relying on any cookies the user has, because the request is made from your web server.

e.g.

<?php
//data to post
$data = array( 'name' => 'tom', 'another_form_field'=>'a' ); 

//external site url (this should be the 'action' of the remote form you are submitting to)
$url = "http://example.com/some/url";  

$curl = curl_init($url);

curl_setopt($curl, CURLOPT_POST, 1);  
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

//make curl return the content returned rather than printing it straight out
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  

$result = curl_exec($curl);

if ($result === false) {
    //curl error   
}

curl_close($curl);

//this is what the webserver sent back when you submitted the form
echo $result;
