The hidden object is another input type, just like the text, radio button, and checkbox types. A hidden variable looks like the following in HTML:
As you would expect, this tag has no representation when it??™s viewed through a browser. However, Dreamweaver does display a Hidden Form Element symbol in the Document window. You can turn off the display of this symbol by deselecting the Hidden Form Field option from the Invisible Elements category of Preferences. NOTE NOTE 510 Adding Advanced Design Features Part III The file input type The file input type, which enables any stored computer file to be attached to the form and sent with the other data, is rarely used. Formerly, it was used primarily to enable the easy sharing of data. The file input type has now been largely supplanted by modern e-mail methods, which enable files to be attached to messages. The file field is inserted in a form much like the other form elements. Place your cursor in the desired position and choose Insert ??? Form ??? File Field or click the File Field button in the Forms category of the Insert bar. Dreamweaver automatically inserts what appears to be a text box with a Browse button. In a browser, the user??™s selection of the Browse button displays a standard Open File dialog box from which a file can be selected to go with the form.
