The form tag in HTML allows users to submit information to a server using different input types. Forms can be defined with attributes such as action and method, and must include a submit button. The action script determines what happens next, and there are two methods for submitting form information: get and post. Forms are used for various purposes, such as login, online orders, and surveys. Other languages like JavaScript can enhance their functionality.
In HTML, the form tag is used to designate an area of a web page that the user can interact with to submit information. A form tag is defined using a specific format. Within the form tag, you can use a variety of different inputs such as simple text fields and checkboxes. When a form is submitted, the information is passed to a server which can act on the information immediately or store it in a database. There are two methods used to submit an HTML form called “get” and “post”.
Between the two form tags, individual elements are placed including a submit button. Usually a form tag is defined with the “action” and “method” attributes. Action is the script used to process information and method is how data is transferred to that script. In many cases, the script will be used to populate the information from the form into a database for further reference.
Some common input types that can be used within the form tag include text fields, radio buttons, and drop-down boxes. A password field can also be used which hides the data entered by the user. All forms must end with a submit button which is used to submit the information to the server. Each field in a form must have a unique name so that fields of the same input type can be distinguished from each other.
When users enter data into a form and click submit, the action script decides what happens next. For a simple search box, the data can be used immediately without the need to enter it into a database. A registration form will use an action script to format the data provided by the user and then register it.
There are two methods used to submit form information. “Get” is used to send data in the URL by adding a question mark followed by the information. The “Post” data is sent in the form body to the processing script.
There are many examples of the form tag on the Internet. For example, any website that requires a login uses a simple form to compare user details against those in a database. In this case a password field will be used to keep the user’s password private. Online order forms, signup pages, and surveys also use forms. While HTML tags are used for any form of website, the layout or functionality may be enhanced by other languages, including JavaScript.
