For defining an area to solicit user input, ranging from selecting buttons or check boxes, to areas for text input.
ACTION="URL"
URL is a standard uniform resource locator; ACTION specifies the name of a resource for the browser to execute as an action in response to clicking on on-screen Submit or Reset button. The URL will typically point to a CGI script, or other executable service on a Web server that performs an action in response to being accessed.
The METHOD attribute tells the browser how to interact with the service designated by the ACTION's URL.
If GET is used, the browser constructs a query URL that consists of the URL of the current page that contains the form, followed by a question mark, followed by the values of the form's input areas and other objects. The browser sends this query URL to the target URL specified by ACTION, which uses the information supplied to perform a search, process a query, or provide whatever services it has been programmed to deliver.
If POST is used, the browser sends a copy of the form's contents to the recipient URL as a data block to the standard input service. This makes it easy to grab and process, which is why POST is the preferred method for most HTML programmers.
Anything the recipient program writes to output will be returned as a new HTML document to the sender for further display or interaction.
<FORM> ... </FORM> is legal within:
<BLOCKQUOTE> <BODY> <DD> <LI>
The following markup can be used within <FORM> ... </FORM>
<ADDRESS> <BLOCKQUOTE> <DIR> <DL> <H*> <HR> <INPUT> <ISINDEX> <MENU> <OL> <P> <PRE> <SELECT> <TEXTAREA> <UL>
Use <FORM> ... </FORM> whenever you want to solicit input from users, or to provide additional back-end services through your Web pages.
Please see the Fill In Forms tutorial for examples.
