<input type="text" name="url" id="longurl" class="txt-box" size="45" placeholder="Enter URL To Shorten..."/>
<input type="submit" value="Shorten" class="btn" name="submit" />
</form>

<?php
    session_start();

    $url = $_POST['url'];
    $key = 'https://www.googleapis.com/urlshortener/v1/url';
    $googer = new URLAPI($key);

    $shortDWName = $googer->shorten($url);
    echo $shortDWName;

    class UrlApi {

        function URLAPI($key,$apiUR = 'https://www.googleapis.com/urlshortener/v1/url?key=AIzaSyC-MuCl9FiuXwhrEB1h_kVByBDkryg_zAM') {
            $this->apiURL = $apiURL.'?key='.$key;
        }

        function shorten($url) {
            $response = $this->send($url);
            return isset($response['id']) ? $response['id'] : false;
        }

        function send($url,$shorten = true) {
            $ch = curl_init();
            if($shorten) {
                curl_setopt($ch, CURLOPT_URL, $this->apiURL);
                curl_setopt($ch, CURLOPT_POST, 1);
                curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(array("longUrl"=>$url)));
                curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
            }
            else {
                curl_setopt($ch,CURLOPT_URL,$this->apiURL.'&shortUrl='.$url);
            }

            curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

            $result = curl_exec($ch);

            curl_close($ch);

            return json_decode($result,true);
        }       
    }

    header("Location: ../coupon.php?id=" . $id . "&code=" . $_SESSION['code']);
?>
<?php
    session_start();

    $url = $_POST['url'];

    $longUrl = 'http://www.mysite.com/$url';

    // Get API key from : http://code.google.com/apis/console/
    $apiKey = 'mykeyapi';

    $postData = array('longUrl' => $longUrl, 'key' => $apiKey);
    $jsonData = json_encode($postData);

    $curlObj = curl_init();

    curl_setopt($curlObj, CURLOPT_URL, 'https://www.googleapis.com/urlshortener/v1/url');
    curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curlObj, CURLOPT_HEADER, 0);
    curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($curlObj, CURLOPT_POST, 1);
    curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);

    $response = curl_exec($curlObj);

    // Change the response json string to object
    $json = json_decode($response);

    curl_close($curlObj);

    $shortLink = get_object_vars($json);
    echo "Shortened URL is: ".$shortLink['id'];
    //header("Location: ../coupon.php?id=" . $id . "&code=" . $_SESSION['code']);
?>

this code is not working either

Notice: Undefined index: id in C:\wamp\www\webapp\includes\linkshort.php on line 32

What does not work? Check for response errors.

Notice: Trying to get property of non-object in C:\wamp\www\webapp\includes\linkshort.php on line 29
Call Stack

That's just a notice, most likely because the call fails. I repeat, add error checking.

I have tried link with another website when I tried to coonect with another website in google it was working but wi this t i not working the website is po.st

i am getting this error

Notice: Undefined property: stdClass::$id in C:\wamp\www\webapp\includes\linkshort.php on line 29

this is my code

    session_start();

    $url    = $_POST['url'];
    $idnew  = $_GET['id']; 
    $longUrl = $url;

    $apiKey = 'myApi';

    $postData = array('longUrl' => $longUrl, 'key' => $apiKey);
    $jsonData = json_encode($postData);

    $curlObj = curl_init();

    curl_setopt($curlObj, CURLOPT_URL, 'http://po.st/api/shorten?apiKey='.$apiKey);
    curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curlObj, CURLOPT_HEADER, 0);
    curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($curlObj, CURLOPT_POST, 1);
    curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);

    $response = curl_exec($curlObj);

    $json = json_decode($response);

    curl_close($curlObj);

    $geturl = $json->id;

    echo 'Shortened URL is: '.$geturl;

You still haven't added any error checking. You need to check the curl response, because apparently it is not returning an object with an id.

Okay can you please let me know how to check the error please

{"status_txt":"AUTH_ERROR","status_code":41}

Look it up in the documentation for the API you use.

Hello,

getting the response correctly but having some error

Undefined property: stdClass::$id in

$curlObj = curl_init();

    curl_setopt($curlObj, CURLOPT_URL, 'http://po.st/api/shorten?longUrl=http%3A%2F%2F'.$longUrl.'%2F&apiKey='.$apiKey);
    curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($curlObj, CURLOPT_HEADER, 0);
    curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($curlObj, CURLOPT_POST, 1);
    curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);

    $response = curl_exec($curlObj);

    $json = json_decode($response);

    curl_close($curlObj);

    print_r($geturl = $json->id);

    echo 'Shortened URL is: '. $geturl;

print_r($json = json_decode($response));

response

stdClass Object ( [long_url] => http://funmaza.com/ [hash] => qZ0cKy [short_url] => http://selv.co/qZ0cKy [new_hash] => 0 [alt_hashes] => Array ( ) [status_txt] => OK [status_code] => 0 )

There is no id, so you cannot use it.

Got it done with the solution now thank you
