What is enctype in HTML forms?
enctype: You can use the enctype attribute to specify how the browser encodes the data before it sends it to the server.
application/x-www-form-urlencoded - This is the standard method most forms use. It converts spaces to the plus sign and non-alphanumeric characters into the hexadecimal code for that character in ASCII text.
mutlipart/form-data - This allows the data to be sent in parts, with each consecutive part corresponding the a form control, in the order they appear in the form. Each part can have an optional content-type header of its own indicating the type of data for that form control.
