Question

I want to upload two different files to two different servers located in two different locations.

I have one image file which I want to upload onto my server where the PHP script is hosted and the other video file which I want to upload to some other server not on the same server.

Is there any possibility of doing this? Can anyone explain me how to achieve this if possible?

Answer 1

This is impossible with an HTML form – the action attribute only allows for a single URL to be specified.

You have a couple of choices here:

• Use JavaScript to create two <iframe>s, fill them with the data you want to submit in a <form>, and then call .submit() on each of the forms. Since you mentioned that the two locations are on different servers, I’ll assume they are on different domains as well – and therefore you will run into trouble with the same-origin policy on at least one of the forms. For that reason, and the fact that quite a few users have JavaScript turned off in their browser, I recommend avoiding this option if possible.

• Have the PHP script on your server take the $_POST data and send a POST request with that information to the other server. This can easily be done with PHP’s cURL extension, for example. This can be done as follows:

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, 'http://...');
  curl_setopt($ch, CURLOPT_POST, TRUE);
  curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($_POST));
  curl_exec($ch);
  curl_close($ch);
