my php POST request script always returns error,and i have no idea why.
i tried different approaches and still no luck.
when i try this, it returns
'Not Found
Sorry, we could not find a page at that URL.'
why?there is a page at that URL 100%
here is the code
$params = array(
'apiKey' =>'*********',
'titleID' => $title,
'forename' => $yname,
'surname' => $surname,
'dayPhone' => $phone,
'eveningPhone' => $phone_evening,
'mobilePhone' => $phone_mobile,
'email' => $email,
'buyingBedrooms' => $bedroom_num,
'buyingMinPrice' => $min_budget,
'buyingMaxPrice' => $max_budget,
'buyingNotes' => $message,
'buyingActive' => true
);
function httpPost($url,$params)
{
$postData = '';
foreach($params as $k => $v)
{
$postData .= $k . '='.$v.'&';
}
$postData = rtrim($postData, '&');
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POST, count($postData));
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
$output=curl_exec($ch);
if($output === false)
{
echo "Error Number:".curl_errno($ch)."<br>";
echo "Error String:".curl_error($ch);
}
curl_close($ch);
return $output;
}
echo httpPost("http://daisylets.domus.net/site/go/api/saveRegistration",$params);
Any help appreciated.

Answer 1

Without seeing the data, it is impossible to tell, but a potential problem is that you could be breaking your own query string:
$postData = '';
foreach($params as $k => $v)
{
$postData .= $k . '='.$v.'&';
}
$postData = rtrim($postData, '&');
You are not encoding your values so any character that has a special meaning in a url / has to be encoded in a url, will break your cURL request.
You should replace that whole section with just:
$postData = http_build_query($params);

Answer 2

Try encoding the URL
$postUrl = urlencode("http://daisylets.domus.net/site/go/api/saveRegistration");
echo httpPost($postUrl,$params);
