Get and post HTML

Definition and Usage

The method attribute specifies how to send form-data (the form-data is sent to the page specified in the action attribute).
The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post").
Notes on GET:
  • Appends form-data into the URL in name/value pairs
  • The length of a URL is limited (about 3000 characters)
  • Never use GET to send sensitive data! (will be visible in the URL)
  • Useful for form submissions where a user want to bookmark the result
  • GET is better for non-secure data, like query strings in Google
Notes on POST:
  • Appends form-data inside the body of the HTTP request (data is not shown is in URL)
  • Has no size limitations
  • Form submissions with POST cannot be bookmarked
Example
<form action="demo_form.asp" method="get">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <input type="submit" value="Submit">
</form>
