What is meant by method equals post in HTML language?

Answer 1

method="POST" is a common attribute of the HTML <form> tag. What this does is tells the form that it needs to "post" the data to whatever file you have specified in your "action" attribute of the form tag. So your form tag might look something like this:

<form action="receive.php" method="POST">Insert form data here</form>

Again, this will tell the form to post all the data that the user has entered into it to the receive.php file.
