Form Field Template

In this article, you’ll learn how to create a Liferay form field as a Liferay module. To create a Liferay form field via the command line using Blade CLI or Maven, use one of the commands with the following parameters:

blade create -t form-field -v 7.0 [-p packageName] [-c className] projectName

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.form.field \
    -DartifactId=[projectName] \
    -Dpackage=[packageName] \
    -DclassName=[className] \
    -DliferayVersion=7.0

You can also insert the -b maven parameter in the Blade command to generate a Maven project using Blade CLI.

The template for this kind of project is form-field. Suppose you want to create a form field project called my-form-field-project with a package name of com.liferay.docs.form.field and a class name prefix of MyFormField. You could run one of the following commands to accomplish this:

blade create -t form-field -v 7.0 -p com.liferay.docs -c MyFormField my-form-field-project

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.form.field \
    -DgroupId=com.liferay \
    -DartifactId=my-form-field-project \
    -Dpackage=com.liferay.docs \
    -Dversion=1.0 \
    -DclassName=MyFormField \
    -Dauthor=Joe Bloggs \
    -DliferayVersion=7.0

After running the command above, your project’s directory structure looks like this:

• my-form-field-project
  • gradle (only in Blade CLI generated projects)
    • wrapper
      • gradle-wrapper.jar
      • gradle-wrapper.properties
  • src
    • main
      • java
        • com/liferay/docs/form/field
          • MyFormFieldDDMFormFieldRenderer.java
          • MyFormFieldDDMFormFieldType.java
      • resources
        • content
          • Language.properties
        • META-INF
          • resources
            • config.js
            • my-form-field-project.soy
            • my-form-field-project_field.js
  • bnd.bnd
  • build.gradle
  • [gradlew|pom.xml]

The generated module is a working form field and is deployable to a Liferay DXP instance. To build upon the generated app, modify the project by adding logic and additional files to the folders outlined above.
