FORM:
Attributes


ACTION

Specifies the action URI for the form. The action URI of a form defaults to the base URI of the document.

Value(s)

CDATA

Default Value

#IMPLIED

ENCTYPE

Specifies the media type used to encode the name/value pairs for transport, in case the protocol does not itself impose a format.

The default encoding for all forms is 'application/x-www-form-urlencoded'. A form data set is represented in this media type as follows:

  1. The form field names and values are escaped: space characters are replaced by `+', and then reserved characters are escaped as per URL; that is, non-alphanumeric characters are replaced by `%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks, as in multi-line text field values, are represented as CR LF pairs, i.e. `%0D%0A'.
  2. The fields are listed in the order they appear in the document with the name separated from the value by `=' and the pairs separated from each other by `&'. Fields with null values may be omitted. In particular, unselected radio buttons and checkboxes should not appear in the encoded data, but hidden fields with VALUE attributes present should.
    NOTE
    The URI from a query form submission can be used in a normal anchor style hyperlink. Unfortunately, the use of the `&' character to separate form fields interacts with its use in SGML attribute values as an entity reference delimiter. For example, the URI `http://host/?x=1&y=2' must be written `<a href="http://host/?x=1&#38;y=2">' or `<a href="http://host/?x=1&amp;y=2">'.

    HTTP server implementors, and in particular, CGI implementors are encouraged to support the use of `;' in place of `&' to save users the trouble of escaping `&' characters this way.
