Insert ColdFusion hidden fields

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.
  1. In Design view, place the insertion point inside the form outline.
  2. 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.

  3. 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.

    Label
    Lets you specify a label for the control. This property is ignored by the ColdFusion server at run time.

    Pattern
    Lets you specify a JavaScript regular expression pattern to validate input. Omit leading and trailing slashes. For more information, see the ColdFusion documentation.

    Height
    Lets you specify the height of the control, in pixels. This property is ignored by the ColdFusion server at run time.

    Width
    Lets you specify the width of the control, in pixels. This property is ignored by the ColdFusion server at run time.

    Size
    Lets you specify the size of the control. This property is ignored by the ColdFusion server at run time.

    Required
    Lets you specify whether the hidden field must contain data before the form is submitted to the server.

    Display Tag Editor
    Lets you edit properties not listed in the Property inspector.
