All About HTML Forms

The two things you must have when it comes to using the form tag is one the action attribute and second the method attribute. I also often use the enctype attribute when doing file uploads.

<form action="get-data.html" method="post" enctype="multipart/form-data"> </form>

The method attribute takes 'get' or 'post'. Get will send the data in plain text in the URL (not secure for more sensitive information) while post sends data as a http post transaction (more secure).

The enctype attribute specifies how the form data is encoded when submitting it to the server. I generally use enctype="multipart/form-data" when uploading a file. No characters are encoded, but it is necessary for file transactions.
