Laravel 5: how to redirect with data to external resource form controller

问题

I want to send user to payment gate. Normally it could be made by this form:

<form method="post" action="https://demo.moneta.ru/assistant.htm">
    <input type="hidden" name="MNT_ID" value="12345678">
    <input type="hidden" name="MNT_TRANSACTION_ID" value="000001">
    <input type="hidden" name="MNT_CURRENCY_CODE" value="USD">
    <input type="hidden" name="MNT_AMOUNT" value="123.45">
    <input type="submit" value="Pay">
</form>

User press "Pay" and redirect to payment gate.

But I want implement this workflow:

User enter delivery info, payment method, etc.
After that he press "Pay" and
First I want to store data (I do it in my controller)...
... and after that I want redirect user to payment gate. (this is unclear for me)

The question is: how to redirect user to external resource from controller (method should be POST, and I need do send some data such as MNT_ID, etc. (see form example above)?

回答1:

I think this is what you are looking for:

call your function controller:

public function redirectPOST(){
//params
$USERNAME='username';
return view('your vie', compact('USERNAME'));}

then in your view:

<html xmlns="http://www.w3.org/1999/xhtml"><head>
<script type="text/javascript">
 function closethisasap() {
 document.forms["redirectpost"].submit();
  }
 </script>
  </head>
 <body onload="closethisasap();">
 <form name="redirectpost" method="POST" action="http://URL">
 <input type="hidden" id="USERNAME" name="USERNAME" value="{{$USERNAME}}">
 </form>
 </body>
 </html>

It could help you use the Laravel controller as usual and redirect after to the external resource.

In your view redirect the action to your controller:

<form method="post" action={{ action('Controller@method') }}>
    <input type="hidden" name="MNT_ID" value="12345678">
    <input type="hidden" name="MNT_TRANSACTION_ID" value="000001">
    <input type="hidden" name="MNT_CURRENCY_CODE" value="USD">
    <input type="hidden" name="MNT_AMOUNT" value="123.45">
    <input type="submit" value="Pay">
</form>

In your controller:

public function method(Request $request)
{
     // Validate
     // Store
     // ...
     Redirect::away('https://demo.moneta.ru/assistant.htm')->withInputs(Input::all());

}

I didn't test it, but I'm pretty sure that it works (or is near to the solution).

You can get other suggestion from the official guide: http://laravel.com/docs/5.1/responses#redirects

You can redirect to an external URL with Laravels's redirect. First import the Redirect to your controller and

use Illuminate\Support\Facades\Redirect;

return Redirect::away($redirectUrl)->with(['user_id'=>$user_id]);

would help you to send the request as a post with the needed params.
