To add a file upload control to a form, you need do nothing more than make sure that the method and enctype attributes of the form tag are set to "POST" and

"multipart / form-data", respectively, and then add the following HTML to your form:

  < input type="file" name="file1" />

location of the file on the server $file1

      $HTTP_POST_FILES['file1']['tmp_name']

original name of the file on the user's computer $file1_name

      $HTTP_POST_FILES['file1']['name']

If available, type of the file $file1_type

      $HTTP_POST_FILES['file1']['type']

  example ; 

  // test to make sure we got a file

  if (!is_array($HTTP_POST_FILES['file1']))

  {

      echo "You did not upload a file";

      exit;

  }

  // if we got here,

  // we must have gotten

  // something

  $f =& $HTTP_POST_FILES['file1'];

  $dest_dir = 'uploads';

  $dest = $dest_dir . '/' . $f['name'];

  // make sure we can actually

  // put the fie where it's supposed

  // to go

  if (!is_uploaded_file ($f['tmp_name']))

  {

     echo "Error: no file uploaded.";

     exit;

  }

  // all clear, move the file

  // to its permanent location

  $r = move_uploaded_file ($f ['tmp_name'], $dest);

  if ($r == false)

  {  

     // something's wrong

     echo "Error: could not copy file ";

  }
