FORMS IN HTML
HTML forms are used to collect information from the site visitors. Different types of forms can be
created in HTML like sign up/register, application form, feedback form, query form, etc. The three
important components of a form in HTML are: a <FORM> tag, the input controls and buttons.
The <FORM> tag is used to define a form in an HTML document. It is placed within the <BODY>
tag. While designing and building a form, we use different input elements that allow site visitors
to type or select information. These elements can include text fields, radio buttons, checkboxes,
etc. All forms must include a Submit button. When the site visitor fills in the information, then,
it should be sent to the webserver for processing after the Submit button is clicked.
CREATING FORMS
The syntax for creating a form in HTML is:
<FORM NAME = "Name of the form” ACTION = "Script URL" METHOD = "GET/POST">
...(Input Elements)
</FORM>
ACTION: This attribute specifies what action should be taken once the SUBMIT button is
clicked by the user. The Script URL specifies the location where the data collected by the form is
submitted. It also produces a response in return.
METHOD: This attribute specifies what will happen when the form is submitted. Two values can
be assigned to the METHOD attribute, Get and Post.
Get: It is the default value for the METHOD attribute. The form data is sent as the URL
variable, i.e., it appends the form data into the URL. Get value should not be used for sensitive
information.
Post: The form data is sent as an HTTP post transaction and form data is not appended to
the URL. This value is used for submitting sensitive information.
INPUT CONTROLS
Input controls are the elements that are used to accept input from the site visitors. All the controls
have to be filled in before submitting the form. Now, learn the various types of input controls.
