● The <Action> Attribute

● The Method Attribute
The method attribute specifies the HTTP method ( GET / POST ) to be used when submitting the form data.
<form action="/action_page.php" method="get"> or
<form action="/action_page.php" method="post>
<form action="/action_page.php" method="get"> or
<form action="/action_page.php" method="post>
● When to Use GET
The default method when submitting form data is GET.
However, when GET is used, the submitted form data will be visible in the page address field.
● When to Use Post
Always use POST if the form data contains sensitive or personal information. The POST method does not display the submitted form data in the page address field.
POST has no size limitations, and can be used to send large amounts of data.
