从控制器函数返回 iframe 视图

Question

我是 Laravel 的新手。这是我在 SmartpayS 控制器中的功能。我想在 iframe 中返回这个 url。 $url = $item->nodeValue;

function processSmartpaySPayment($paymentType = false, $totalAmount = 0, $currency = false, $payingUserId = false, $quoteId = false, $clubMembershipQuotationId = false)
    {
        $callBackUrl = 'smartpays-payment/response/'.$quoteId;

        if (!empty($payingUserId)) {
            $customerDetails = $this->customerRepo->getCustomerDetails($payingUserId);

        } else {
            return false;
        }

        $testString = $this->smartPaySRepo->createSmartpaySPayment($paymentType, env('ENTERPRISE_ID'), 'DE02', 'ECommerce',env('AUTH_TYPE'), $totalAmount, $customerDetails, $currency, $callBackUrl, $quoteId, $clubMembershipQuotationId, env('STORE_RESULT_PAGE') );
        $dom = new \DOMDocument();
        $dom->formatOutput = TRUE;
        $dom->preserveWhiteSpace = FALSE;
        $dom->loadXml($testString);

        foreach ($dom->getElementsByTagName('redirectURL') as $item) {

           $url = $item->nodeValue;

        }

        return redirect($url);
}

**********iframe is in the view.(paymentload.blade.php)*************


<iframe src="<?php echo $url; ?>" width="600px" height ="800px" ></iframe>

我尝试加载 iframe。但它说“未定义的变量：url” 帮我从控制器函数返回视图中的 iframe。

试试这个

$url = '';
foreach ($dom->getElementsByTagName('redirectURL') as $item) {

  $url = $item->nodeValue;
}

 return redirect($url);

我认为你每次都在添加 $item->nodeValue 所以你应该像这样使用

$url = '';
foreach ($dom->getElementsByTagName('redirectURL') as $item) {

  $url += $item->nodeValue; // check i have added + here 
}

 return redirect($url);
