To make users to upload files can be very useful. Here is an HTML form for uploading files:
<html>
<body>
<form action="upload_file.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
Here the enctype attribute of the <form> tag specifies which content-type to use when submitting the form.
The type="file" attribute of the <input> tag specifies that the input is processed in form of a file.
