About ColdFusion forms

ColdFusion forms provide you with several built-in mechanisms to validate form data. For example, you can check to make sure a user has entered a valid date. Some form controls have additional features. Several do not have HTML counterparts, and others directly support dynamically populating the control from data sources.

Dreamweaver provides a number of enhancements for ColdFusion developers who use ColdFusion MX 7 or later as their development server. These enhancements include more Insert panel buttons, menu items, and Property inspectors so that you can rapidly build and set the properties of ColdFusion forms. You can also generate code that validates the information provided by site visitors. For example, you can check that the e‑mail address provided by a user contains the @ symbol, or that a required text field contains a certain type of value.

Enable the ColdFusion enhancements

Some of these enhancements require that you define a computer running ColdFusion MX 7 or later as a testing server for Dreamweaver. For example, the Property inspectors for form controls are available only if you specify the correct testing server.

You define a testing server only once. Dreamweaver then automatically detects the testing server version and makes the enhancements available if it detects ColdFusion.

  1. If you haven’t already done so, define a Dreamweaver site for your ColdFusion project.
  2. Select Site > Manage Sites, select your site from the list, and click Edit.
  3. Select the Servers category and specify a computer running ColdFusion MX 7 or later as the testing server for your Dreamweaver site. Ensure that you specify a valid Web URL.
  4. Open any ColdFusion document.

    You won’t see any visible changes to the Dreamweaver work space until you open a ColdFusion document.

Create ColdFusion forms

You can use a number of Insert panel buttons, menu items, and Property inspectors to rapidly create ColdFusion forms and set their properties in Dreamweaver.

Merk:

These enhancements are available only if you have access to a computer running ColdFusion MX 7 or later.

  1. Open a ColdFusion page and place the insertion point where you want the ColdFusion form to appear.
  2. Select Insert > ColdFusion Objects > CFForm > CFForm, or select the CFForm category from the Insert panel and click the CF Form icon.

    Dreamweaver inserts an empty ColdFusion form. In Design view, the form is indicated by a dotted red outline. If you don’t see this outline, make sure that View > Visual Aids > Invisible Elements is selected.

  3. Ensure that the form is still selected, and then use the Property inspector to set any of the following form properties.

    CFForm

    Sets the name of the form.

    Action

    Lets you specify the name of the ColdFusion page to be processed when the form is submitted.

    Method

    Lets you define the method that the browser uses to send the form data to the server:

    POST

    Sends the data using the HTTP post method; this method sends the data in a separate message to the server.

    GET

    Sends the data using the HTTP get method, placing the form field contents in the URL query string.

    Target

    Lets you to modify the value of the target attribute of the cfform tag.

    Encoding Type

    Specifies the encoding method used for transmitting the form data.

    Merk:

    Encoding type does not refer to character encoding. This attribute specifies the content type used to submit the form to the server (when the value of method is post). The default value for this attribute is application/x-www-form-urlencoded.

    Format

    Determines what kind of form is created:

    HTML

    Generates an HTML form and sends it to the client. The cfgrid and cftree child controls can be in Flash or applet format.

    Flash

    Generates a Flash form and sends it to the client. All controls are in Flash format.

    XML

    Generates XForms XML and puts the results in a variable with the ColdFusion form name. Does not send anything to the client. The cfgrid and cftree child controls can be in Flash or applet format.

    Style

    Lets you specify a style for the form. For more information, see the ColdFusion documentation.

    Flash/XML Skin

    Lets you specify a halo color to stylize the output. The theme determines the color used for highlighted and selected elements.

    Preserve Data

    Determines whether to override the initial control values with submitted values when the form posts to itself.

    • If False, values specified in the control tag attributes are used.

    • If True, submitted values are used.

    Scripts src

    Specifies the URL, relative to the web root, of the JavaScript file that contains client-side code used by the tag and its child tags. This attribute is useful if the file is not in the default location. This attribute may be required in some hosting environments and configurations that block access to the /CFIDE directory. The default location is set in the ColdFusion Administrator; by default, it is /CFIDE/scripts/cfform.js.

    Archive

    Specifies the URL of downloadable Java classes for cfgrid, cfslider, and cftree applet controls. The default location is /CFIDE/classes/cfapplets.jar.

    Height

    Specifies the height of the form.

    Width

    Specifies the width of the form.

    Display Tag Editor for cfform

    Lets you edit properties not listed in the Property inspector.

  4. Insert ColdFusion form controls.

    Place the insertion point where you want the ColdFusion form control to appear in the ColdFusion form, and then select the control from the Insert menu (Insert > ColdFusion Objects > CFForm), or from the CFForm category in the Insert panel.

  5. If required, set the properties of the control with the Property inspector.

    Make sure the control is selected in Design view and then set the properties in the Property inspector. For more information on the properties, click the Help icon in the Property inspector.

  6. Adjust the layout of the ColdFusion form.

    If you’re creating an HTML-based form, you can use line breaks, paragraph breaks, preformatted text, or tables to format your forms. You cannot insert a ColdFusion form in another ColdFusion form (that is, you cannot overlap tags), but you can include more than one ColdFusion form in a page.

    If you’re creating a Flash-based form, use Cascading Style Sheets (CSS) styles to lay out your form. ColdFusion ignores any HTML in the form.

    Remember to label the ColdFusion form fields with descriptive text to let users know what they are responding to. For example, create a “Type your name label” to request name information.

Insert ColdFusion form controls

Use the Insert panel or Insert menu to quickly insert ColdFusion form controls into a ColdFusion form. You need to create a blank ColdFusion form before inserting controls in it.

Merk:

These enhancements are only available 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. Select the control from the Insert menu (Insert > ColdFusion Objects > CFForm), or from the CFForm category in the Insert panel.
  3. Click the control on the page to select it and then set its properties in the Property inspector.

    For information on the properties of specific controls, see the topics about the controls.

Insert ColdFusion file fields

You can visually insert a ColdFusion file field into your form and set its properties. Use a file field to let users select a file from their computer, such as a word processing document or a graphics file, and upload it to the server. A ColdFusion file field looks like other text fields, except it also has a Browse button. Users can manually enter the path to the file they want to upload, or use the Browse button to locate and select the file.

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 that you specify in the form’s Action box. Contact your server administrator to confirm that anonymous file uploads are allowed before using a file field in your form.

File fields also require that the form encoding be set to multipart/form. Dreamweaver sets this automatically when you insert a file field control.

Merk:

This enhancement is available only if you have access to a computer running ColdFusion MX 7 or later.

  1. In Design view, select the CFForm to display its Property inspector.

    To quickly select the form, click anywhere in the form outline and click the <cfform> tag in the tag selector at the bottom of the Document window.

Validate ColdFusion form data

You can build ColdFusion forms in Dreamweaver that check the contents of specified fields to ensure the user entered the correct data type.

Merk:

This enhancement is available only if you have access to a computer running ColdFusion MX 7 or later.

  1. Create a ColdFusion form that includes at least one input field and one Submit button. Ensure that every ColdFusion field that you want to validate has a unique name.
  2. Select a field in the form that you want to validate.
  3. In the Property inspector, specify how you want to validate the field.

    The lower part of each input Property inspector contains controls to help you define the specific validation rule. For example, you might want to specify that a text field should contain a telephone number. To do this, select Telephone from the Value pop‑up menu in the Property inspector. You can also specify when to validate from the Validate At pop‑up menu.
