Setting up special HTML elements
A number of special HTML elements let you add images to your form buttons, insert hidden data, include cryptographic keys, and interactive file browsers.
The Input Image icon inserts an image, such as a graphical Submit button. Inserting graphics can help viewers navigate through your pages.The Hidden icon inserts an HTML tag that does not display in the browser but whose values are submitted with the form. This tag is used to send additional information in browser-server exchanges.The Key Generator icon lets viewers address an encryption algorithm for safeguarding transactions with your Web site. For more information on cryptographic issues associated with forms, contact your ISP's webmaster.The File Browser icon inserts a file selection dialog box, but is rarely used.
To insert an input image placeholder:
1 Drag the Input Image icon from the Forms tab ( ) of the Objects palette to your document window, or double-click the icon in the Objects palette.
2 Select the placeholder in the document window, and set the options in the Image Inspector.
3 Link the image placeholder with a graphic using the Point and Shoot button, drag and drop, or the Browse button of the image Inspector.
4 In the More tab of the Form Image Inspector, set up the input image. Two items are important for inputting images:
Select Form, if you plan to use the image as a clickable button. (This is selected by default.)Be sure to enter a name in the Name text box to identify the input image as a unique item. This is especially important if you are using several graphical submit buttons within the same form. The text you enter in the Name text box is appended to the x and y coordinates sent to the CGI script to indicate that viewers have clicked a specific input image on the page, and to trigger a button-specific action.
To set up a hidden tag, key generator, or file browser:
1 Drag the Hidden, Key Generator, or File Browser icon from the Forms tab () of the Objects palette to your page, or double-click the icon in the Objects palette.
A. Hidden icon B. Key Generator icon C. File Browser icon
2 Select the icon in the document window. In the Inspector, name the tag by typing in a unique name in the Name text box.
3 Enter a value:
For a Hidden tag, type a default value in the Value text box.For a Key Generator tag, type the security level in the Challenge text box.For a File Browser, in the Visible text box, type a numerical value to determine the width of the file browser window.
