revision:
This attribute is used on the <form> element.
It specifies how the form-data should be encoded when submitting it to the server.
It can be used only if method="post".
<form enctype="value"></form>
enctype attribute can have the following values:
application/x-www-form-urlencoded: default; all characters are encoded before sent (spaces are converted to "+" symbols, and special characters are converted to ASCII HEX values).
multipart/form-data: this value is necessary if the user will upload a file through the form.
text/plain: sends data without any encoding at all. Not recommended.
