Php 找不到'；取消返回'；paypal沙箱页面上的选项，使用codeigniter和paypal库

我正在尝试在我的Codeigniter项目中使用paypal库

我能够导航到paypal n在沙盒上为产品付费，问题是

paypal上没有取消重新运行选项

付款完成后没有返回url

下面的代码是我的控制器代码

$this->load->library('paypal');

    $config['business']             = 'QD8HYTTSE4M38';
    $config['cpp_header_image']     = ''; //Image header url [750 pixels wide by 90 pixels high]
    $config['return']               = 'main/viewAds/info.php';
    //echo $config['return'];

    $config['cancel_return']        = $this->config->base_url() .'main/viewAds/22';
    $config['notify_url']   = $this->config->base_url() .'main/viewAds/30';

    $config['production']           = FALSE; //Its false by default and will use sandbox

    $config["invoice"]              = '843843'; //The invoice id

    $this->load->library('paypal',$config);

    #$this->paypal->add(<name>,<price>,<quantity>[Default 1],<code>[Optional]);

    $this->paypal->add('T-shirt',1,1); //First item


    $this->paypal->pay(); //Proccess the payment

下面是图书馆

这是我得到的交易页面

我期待它回到我的网站，但它只是停留在那里

请告诉我该怎么做。谢谢。

您使用的这个库显然使用的是PayPal标准，这并不保证用户会返回您的站点

您可以在PayPal帐户配置文件中启用自动返回功能，但是，如果用户在重定向发生之前关闭浏览器或转到其他位置，他们将无法返回

如果你想确保你总是回到贝宝，你需要切换到，这确实保证了用户最终会回到你的网站。我有一个很好的方法，可以让你很简单。这是我继续维护的主要版本，它与Composer一起工作，所以您可以使用它自动加载并使其在CI中可用

或者，我有一个旧的，你可能想用它来代替。现在它已经落后不远了，但我不会像我是第一个那样保持它

无论哪种方式，你都会和他一起工作

我还建议你看看。它将允许您根据进入您帐户的交易实时自动化任务，而不管用户是否返回您的站点
