Dynamic sites, pages and web forms

Last updated 6/3/2015

File fields require that you use the POST method to transmit files from the browser to the server. The file is posted to

the address you specify in the form’s Action box.

Note: Contact your server’s administrator to confirm that anonymous file uploads are allowed before using the file field.

1 Insert a form in the page (Insert > Form).

2 Select the form to display its Property inspector.

3 Set the form Method to POST.

4 From the Enctype pop-up menu, select multipart/form-data.

5 In the Action box, specify the server-side script or page capable of handling the uploaded file.

6 Place the insertion point inside the form outline, and select Insert > Form > File Field.

7 Set any of the following options in the Property inspector:

File Field Name Specifies the name for the file field object.

Char Width Specifies the maximum number of characters that can be displayed in the field.

Max Chars Specifies the maximum number of characters the field will hold. If the user browses to locate the file, the

filename and path can exceed the specified Max Chars value. However, if the user attempts to type in the filename

and path, the file field will only allow the number of characters specified by the Max Chars value.

Insert an image button

You can use images as button icons. Using an image to perform tasks other than submitting data requires attaching a

behavior to the form object.

1 In the document, place the insertion point inside the form outline.

2 Select Insert > Form > Image Field.

The Select Image Source dialog box appears.

3 Select the image for the button in the Select Image Source dialog box, and click OK.

4 Set any of the following options in the Property inspector:

ImageField Assigns a name to the button. Two reserved names, Submit and Reset, tell the form to submit the form

data to the processing application or script, or to reset all the form fields to their original values, respectively.

Src Specifies the image you want to use for the button.

Alt Lets you enter descriptive text in case the image fails to load in the browser.

Align Sets the align attribute of the object.

Edit Image Starts your default image editor and opens the image file for editing.

Class Lets you apply CSS rules to the object.

5 To attach a JavaScript behavior to the button, select the image, and then select the behavior in the Behaviors panel

(Window > Behaviors).

Hidden field object options

HiddenField Specifies the name for the field.

Value Assigns a value to the field. This value is passed to the server when the form is submitted.
