支付网关不显示成功/失败

Question

我想制作自定义付款方式选项。客户选择支付的金额。这个过程很简单客户填写表格，无论表格中的金额是多少，都会被重定向到付款页面。之后，它返回到该站点。 我的代码在支付网关页面之前运行完美，之后页面没有获取/运行成功或失败功能。

这是我的表单的前端。

function make_my_payment() {
    if (isset($_POST['formset']) and!empty($_POST['formset'])) {
        require_once dirname(__FILE__).
        '/payu.php';
        date_default_timezone_set('Asia/Kolkata');
        //update the live credentials once done testing.
        /* Payment success logic goes here. */
        function payment_success() {
            //echo "<pre>";
            //print_r($_POST);die;
            global $wpdb;
            $wpdb - > insert('wp_payment_details', array('payment_id' => $_POST['mihpayid'], 'fname' => $_POST['firstname'], 'lname' => $_POST['lastname'], 'email' => $_POST['email'], 'phone' => $_POST['phone'], 'branch' => $_POST['udf1'], 'amount' => $_POST['udf4'], 'total_amount' => $_POST['amount'], 'additional_charge' => $_POST['udf2'], 'notification' => $_POST['udf3'], 'payment_datetime' => time(), 'notification_datetime' => $_POST['udf5'], 'status' => 1, ));
            //send text message
            $text_message = "Thank%20you%20for%20the%20payment%20of%20".$_POST['amount'].
            "%20at%20Nikita%20Jewellers.";
            $ch1 = curl_init();
            curl_setopt($ch1, CURLOPT_URL, "http://makemysms.in/api/sendsms.php?username=NIKITAJWL&password=NIKITA123&sender=NIKITA&mobile=".$_POST['phone'].
                "&type=1&message=".$text_message);
            curl_setopt($ch1, CURLOPT_RETURNTRANSFER, true);
            $output = curl_exec($ch1);
            curl_close($ch1);
            echo '<h4>You have successfully paid amount '.$_POST['amount'].
            '</h4>';
        }

        function payment_failure() {
            /* Payment failure logic goes here. */
            echo "Payment Failure";
        }
        /* Payments made easy. */
        pay_page(array('key' => '4XKLg4', 'txnid' => uniqid('nikita_'), 'amount' => $_POST['total_amount'], 'firstname' => $_POST['fname'], 'lastname' => $_POST['lname'], 'email' => $_POST['email'], 'phone' => $_POST['phone'], 'udf1' => $_POST['orderScheme'], 'udf2' => $_POST['additional_charge'], 'udf3' => $_POST['send_notification'], 'udf4' => $_POST['amount'], 'udf5' => $_POST['notification_date'], 'productinfo' => 'Nikita Make payment', 'surl' => 'payment_success', 'furl' => 'payment_failure'), 'jeYETVtZ');
        /* And we are done. */
    }
    if (empty($_POST['formset'])) {
        $html. = "<form id='payment_form' method='post'> < table border = '0'

        ";
        return $html;
    }

支付网关的 Payu.php 文件已针对此表单进行了修改，因此发布了我修改的确切代码。

public static
function show_page($result) {
    if ($result['status'] === Misc::SUCCESS) {
        //                      header( 'Location:' . $result['data'] );
        //              else
        //                      throw new Exception( $result['data'] );
        //
        //                        echo ($result ['data']);
        $nik = $result['data'];
        echo '<META HTTP-EQUIV="refresh" content="0;URL='.$nik.
        '">';
        echo "<script type='text/javascript'>document.location.href='{$nik}';</script>";
        $result['data'] = $nik;
    } else throw new Exception($result['data']);
    echo($result['data']);
}
public static
function show_reponse($result) {
    if ($result['status'] === Misc::SUCCESS) {
        $result['data']();
        //                     echo "<script type='text/javascript'>alert('$result['data']());</script>";
    } else {
        return $result['data'];
        //                    $nik=$result['data'];
        //                   echo "<script type='text/javascript'>alert('$nik');</script>";
    }
}
}

在支付 Payu 文件中，我必须删除 PHP 重定向，因为它给出了已经发送的错误标头所以我不得不使用 javascript 进行重定向。那么我现在应该怎么做才能让它获得完美的成功/失败信息。

Answer 1

标头在输出开始时发送，因此请检查任何过早的输出（如 PHP 开头标记之前的空格等）。重新启用 PHP 重定向并让它做它的事情。关键是在那之前不要输出任何东西。我们需要查看更多代码才能知道该页面中是否有我们可以提供帮助的内容。

这是 StackOverflow 中关于查找已发送标头问题原因的参考：Link。
