Redirecting to payumoney in laravel using Curl

I want to redirect to payumoney gateway from my php server using curl.

I am using laravel framework and i dont want to use html/blade method to trigger payment gateway.

$posted = array();

$posted['key'] = $MERCHANT_KEY;
$posted['hash'] = $hash;
$posted['txnid'] = $txnid;
$posted['firstname'] = $firstname;
$posted['email'] = $email;
$posted['phone'] = $phone;
$posted['amount'] = $amount;
$posted['productinfo'] = $productinfo;
$posted['surl'] = $surl;
$posted['furl'] = $furl;
                
ini_set('display_errors', 1);

$c = curl_init();

$url = "https://test.payu.in/_payment";
curl_setopt_array($c, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => 0,
    CURLOPT_FOLLOWLOCATION => 1,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $posted,
));
$response = curl_exec($c);

But this code is showing below output and thus doesn't redirect to gateway fully

As per this answer, you would have to analyse the response you get from the CURL request.

$response = curl_exec($c);
var_dump($response); // Check the contents of response

In order to do that, please set the

CURLOPT_RETURNTRANSFER => 1,

> true to return the transfer as a string of the return value of curl_exec() instead of outputting it directly.

CURLOPT_RETURNTRANSFER

Based on the response, you may redirect the user to PayUMoney gateway.

if ($response === false) {
    // Transaction not created, navigate the user to the error page.
    return redirect('payment-error');
}

// Transaction is created, everything is okay.
return redirect('payment-page');

$posted = array(
        'key' => $MERCHANT_KEY,
        'hash' => $hash,
        'txnid' => $txnid,
        'firstname' => $firstname,
        'email' => $email,
        'phone' => $phone,
        'amount' => $amount,
        'productinfo' => $productinfo,
        'surl' => $surl,
        'furl' => $furl,
    );



$url = "https://test.payu.in/_payment";
$c = curl_init();
curl_setopt_array($c, array(
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => false,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => http_build_query($posted),
    CURLOPT_HEADER => false,
));
curl_setopt($c, CURLOPT_VERBOSE, true);
curl_setopt($c, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 0);

$response = curl_exec($c);
curl_close($c);

Redirect to the PayUmoney gateway

return Redirect::away($url)->withInput($request->input());

Or you may use:

header("Location: $url");
exit;

<?php

$url = "https://test.payu.in/_payment";
$postdata = http_build_query($posted);
$c = curl_init();

curl_setopt_array($c, array(
    CURLOPT_URL => $url,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $postdata,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => false,
    CURLOPT_HEADER => true,
));
$response = curl_exec($c);

// Close cURL session
curl_close($c);
$redirect_url = '';
$headers = explode("\r\n", $response);
foreach ($headers as $header) {
    if (strpos($header, 'Location: ') === 0) {
        $redirect_url = trim(substr($header, strlen('Location: ')));
        break;
    }
}
if (!empty($redirect_url)) {
    header("Location: $redirect_url");
    exit;
} else {
    echo "Failed to get redirect URL";
}
