Very basic file upload information
By: Daniel

Here is a very basic code that will help you find all the information about a file being uploaded.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
  <meta http-equiv="content-type" content="text/html; charset=windows-1250">
  <title>Very Basic file upload info</title>
  </head>
  <body>
  <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data">
    <input type="file" name="uFile">
    <input type="submit" value="upload">
  </form>
<?php
if($_FILES) {
  $ext = explode('.',$_FILES['uFile']['name']);
  $extension = count($ext) - 1;
  echo 'Type: '.$_FILES['uFile']['type'].'<br>';
  echo 'Name: '.$_FILES['uFile']['name'].'<br>';
  echo 'tmp_name: '.$_FILES['uFile']['tmp_name'].'<br>';
  echo 'Size: '.$_FILES['uFile']['size'].'<br>';
  echo 'Extension: '.$ext[$extension].'<br>';
  move_uploaded_file($_FILES['uFile']['tmp_name'], "/path/to/uploads/".$_FILES['uFile']['name']);
}
?>
  </body>
</html>

The main key to this code is in the form. You MUST include the: 

enctype="multipart/form-data"

The next key part is the input type. You must have an input type as file instead of text.
Then you can just use the $_FILES variable to get all the information you need.

Make sure that you change the “/path/to/uploads/” in the move_uploaded_file() line to the path of where the file will be uploaded to.

If you forget what information you can get from the $_FILES variable just do a print_r($_FILES) and you can see everything.

Hope you enjoy.
