I have a script making a file from data (from a form or not). I have access to the URL to download the file in any browser, using window.URL.createObjectURL. But I would like to add a button to send the file by email. (I have a server and PHP). Here is my code: First creating File from 'test':

function makeFile(text) {
  var test =
    "Here is my " + text;
var data = new File([test], { type: "text/plain" });
  if (myFile !== null) {
    window.URL.revokeObjectURL(myFile);
  }

  myFile = window.URL.createObjectURL(data);

  return myFile;
}

Now my unsuccessful attempt:

<form action="emailthijob.php" method="post">
<a class="download hide" id="sendbyemail" onclick="myFile.submit()";>⇧ Email</a>
</form>

So I would appreciate help with 1/button to click and send mail, 2/ PHP code to actually get the result.

Thank you very much for your help, Best, --Fred
