Question

I am using the following PHP proxy:

//Store the URL
$jURL = $_POST['jURL'];
//Store the POST data
$jData = $_POST['post_data'];

//And let cURL work it's magic.
$ch = curl_init();

//Set the URL
curl_setopt($ch, CURLOPT_URL, $jURL);
//Enable POST data
curl_setopt($ch, CURLOPT_POST, true);
//Use the $pData array as the POST data
curl_setopt($ch, CURLOPT_POSTFIELDS, $jData);

//curl_exec automatically writes the data returned
$response = curl_exec($ch);
curl_close($ch);
echo $response;

and I am calling it by:

  var dataString = { 'Contact': Contact, 'address1': address1, 'address2': address2, 'city': city, 'state': state, 'zip': zip, 'Phone1': primPhone, 'Phone2': secPhone, 'email': email,
                               'key2': key2, 'key5': key5, 'uhsgradyr': uhsgradyr, 'uhighlevel': uhighlevel, 'ucourseint': ucourseint, 'uCampaignID': uCampaignID, 'utextperm':utextperm,
                               'uleaddate': uleaddate, 'uleadtime':uleadtime};

                var postData = {jURL: 'http://test.com/candidate_test.php', postData: dataString};
                $.ajax({
                        type: "POST",
                        url: "proxy.php",
                        data: postData,
                        success: function(data) {
                                 window.location = "thankyou.php";
                        },
                        error:function(xhr, ajaxOptions, thrownError){
                                 console.log(xhr.responseText);
                        }
                });

The issue is that why am I still not getting any response back?

Answer 1

Ok, I actually went to the site.. you need to replace some javascript:

$(".Submit").click(function() { 

should be

$('#form').submit(function(ev) {
    ev.preventDefault();

In the present code, you never say “stop form submission and react to ajax”, which is what ev.preventDefault() does for you.

Old answer:
You should set one more option:

curl_setopt(CURLOPT_RETURNTRANSFER, true);

to make sure $response actually contains the curl’s response. See the documentation on curl_exec().
