The Form module allows you to create Web forms that visitors can fill in. The module provides components for easy creation of standard forms, like contact forms. You can group related form elements such as address fields together visually. Form data can be validated using configurable validators. By default, submitted form data is sent by email. You can process form data with pluggable data processors which allow customization without changing the Magnolia core system. Magnolia forms are fully HTML5 compliant.

Installing

Maven is the easiest way to install the module. Add the following dependency to your bundle:

<dependency>
  <groupId>info.magnolia</groupId>
  <artifactId>magnolia-module-form</artifactId>
  <version>2.3.8</version>
</dependency>

Pre-built jars are also available for download. See Installing a module for help.

Mail configuration

The Form module uses the Mail module to send form data in emails. See Configuring SMTP to enable mail sending.

Creating a form

See an example form on the Contact page of the Travel demo.

To create a form:

  1. Open the page, add the Form component and configure the form settings. Form settings define the title and name of the form, and where the collected information should be submitted.
  2. Add a  field set component to the form.

    You can have multiple field sets in the one form. This helps to groups them visually. For example contact details in one set and feedback message in another etc.

  3. Add a field set.
  4. Add fields inside the field set.
  5. View the form.

Creating a multistep form

See an example multistep form on the Book your tour page of the Travel demo.

Splitting a large form into multiple steps allows the visitor to focus on one step at a time. The substeps are detected automatically. Visitors can move forward and backwards between steps without losing entered data. Each step is validated individually. The form module also allows users to upload files, but the upload field should only be included as the last step of the process.

  1. Add the Form Step component to an area of a template.
    Example: Adding formStep component to main area in a new template.

    /my-module/templates/pages/form.yaml
    templateScript: /my-module/templates/pages/formStep-page-template.ftl
    renderType: freemarker
    visible: true
    title: Form Step Template
    dialog: my-module:pages/form
    areas:
      main:
        availableComponents:
          form:
            id: form:components/formStep
    Node nameValue
     my-module
     

     templates

     

     pages

     

     formStep

     

     areas

     

     main

     

     availableComponents

     

     formStep

     

     id

    form:components/formStep

     dialog

    my-module:pages/form

     renderType

    freemarker

     title

    Form Step Template

     templateScript

    /my-module/templates/pages/formStep-page-template.ftl

     visible

    true

  2. Create a new page based on a template that contains the Form component. This is the first page of the form.
    1. Configure the form settings
    2. Add a field set component
    3. Add fields inside the field set. The Submit button field will automatically navigate to the next step. Conditional steps can be set in the Next step condition component.

  3. Create subpages based on the template that contains the Form Step component (created in 1. above) for the subsequent steps of the form.
    1. Add field sets and fields on the substep forms. Submit button fields will automatically navigate to subsequent or conditional steps and the final button will submit the form.

The purpose of a field set is to group fields that logically belong together:

  • Before you can add any fields on the form you need to add at least one field set component.
  • You can add as many field sets as necessary.
  • Use the Title field to distinguish field sets or include introductory text.
  • Individual field components are added as subcomponents in a field set.
  • Component definition: formGroupFields

Fields

Field components are added within a field set.

Available fields:

FieldDescriptionImage
Input

(warning) 5.4.4+ Password field is deprecated. Use two Input fields with input type Password instead. Validate the second field using the Password validator.

Conditional steps

The Condition list component provides optional, additional business logic to a multistep form. 

  • The component is added automatically after a Submit button field, as an optional area.
  • Allows you to set conditions for subsequent steps in a multistep form.
  • Allows you to define the page the user is directed to, dependent on their entry in a former step. 
     
     

Field validators

Validators are used to ensure that form data is entered in the correct format. For example, an email address should follow established syntax where a local part is followed by the @ character and a domain: john.smith@example.com.

 Choose a validator for appropriate fields in the Validation field. 

 

 When field validation passes, the value is submitted. When field validation fails, the field is highlighted in red and when the user attempts to submit the form a notification message identifies the problem.

  • info.magnolia.module.form.processors.SendContactEMailProcessor (SendContactEMailProcessor): Sends form data in email to the address specified in the To field. The processor extracts values from the From, To, Subject and Text fields and creates an email message in plain text or HTML format depending on form settings. Any uploaded files are sent as attachments.   
  • info.magnolia.module.form.processors.SendConfirmationEMailProcessor (SendConfirmationEMailProcessor): Sends a confirmation email. The processor first verifies if the Send confirmation checkbox is checked and sends a message to the address specified in the To field. By default, this processor is not enabled. This is the case even if the Send confirmation checkbox is checked in form settings. To enable it, add an enabled property under the processor and set the value to true.
  • info.magnolia.module.form.processors.TrackEmailProcessor (TrackEmailProcessor): Writes the content of the submitted form to magnolia-form.log file if the Track Mail checkbox is checked. By default, this processor is not enabled. This is the case even if the Track Mail checkbox is checked in form settings. To enable it, add an enabled property under the processor and set the value to true.

enabled

optional, default is false

Enables and disables the processor

loggerName

required

The logger name. Only relevant for trackEmail processor.

Creating a custom form processor

The three example form processors above send the form data in email, but you can write a custom form processor to do almost anything. If you need to store the data in a database or process it in another way, write your own form processor. You can also try the Form2DB App that is a community developed app that saves form data via form processor into the JCR and allows for export to XLS.

Create a new form component definition for your custom processor. If you simply add the custom processor to the default component definition it will be executed for all forms.

For more examples see Form processors in the PUR module

  • The escapeHtml property escapes any HTML code entered in a form input field. This is a security feature that prevents XSS attacks. Default is true for all form fields.
  • AbstractFormModel ensures that pages with forms are not cached.

Logging form data

To log data sent in the contact form:

  1. In the Form component, check the Track mail checkbox on the Submit settings tab.
  2. Enable the trackEmail form processor.
  3. Submit a form.
  4. To view the log:
    • Go to Tools > LogViewer. Select magnolia-form.log and click View. OR
    • Open /webapps/<webappName>/logs/magnolia-form.log on the file system.
