File Uploads

Adding Fields

First we need to add a file upload field to our frontend, which is easy:

$form->addUpload("test", "test upload");

Processing Uploads

Next, we need to process the upload and maybe save it to a ProcessWire page or send it via email.

Automatic Uploads to Entry Pages

The easiest way is to use the saveEntry() feature for that, which will add all files that it finds in the submitted data to the files field of the entry.

All you have to do is this:

public function processSuccess()
{
  // save entry to backend
  $values = $this->values();
  $entry = $this->saveEntry("Contact Form by {$values->email}");
}

Sending Uploads via E-Mail

Now that we have our files on the system we can send them via email easily:

public function processSuccess()
{
  // save entry to backend
  $values = $this->values();
  $entry = $this->saveEntry("Contact Form by {$values->email}");

  // send email
  $mail = new WireMail();
  // from, to, etc...
  foreach ($entry->files() as $file) {
    $mail->attachment($file->filename);
  }
  $mail->send();
}
