You
can visually insert a ColdFusion hidden field into your form and
set its properties. Use hidden fields to store and submit information
that the user does not enter. The information is hidden from the
user.
Note: This enhancement is available only if you have access
to a computer running ColdFusion MX 7 or later.
In Design view, place the insertion point inside
the form outline.
In the CFForm category of the Insert bar, click the CF
Hidden Field icon.
A marker appears in the ColdFusion form. If you don’t see
the marker, select View > Visual Aids >
Invisible Elements.
Select the hidden field on the page and set any of the
following options in the Property inspector:
Cfhiddenfield
Lets you specify the unique name for the hidden field.
Value
Lets you specify a value for the hidden field. The data
can either be static or dynamic.
To specify a dynamic value,
click the lightning bolt icon beside the Value box and select a
recordset column in the Dynamic Data dialog box. The recordset column supplies
a value to the text field when you view the form in a browser.
Validate
Specifies the type of validation for the current field.
Validate At
Specifies when the field is validated: onSubmit, onBlur
or onServer.
