How to add or get custom field data in liferay portal using API

Liferay is providing the following remote service com.liferay.portlet.expando.service.impl.ExpandoValueServiceImpl which can be used for adding/selecting/updating the custom field data.

Here are the parameters to be passed in:

1.    CompanyId: company id that is assigned

2.    Class Name: The entity name that we have created the custom attribute for

3.    TableName: Is always CUSTOM_FIELDS

4.    ColumnName: The name given for the attribute

5.    classPK: Primary key value within the entity.

6.    Data: the value to be updated.

For adding or updating a single field, The API is ‘/expandovalue/add-value'.

For adding or updating multiple fields the API is ‘/expandovalue/add-values'.

For getting the data (single or multiple) the API is '/expandovalue/get-data' 

Below are the sample examples - Language is the custom field added.

For Add

Liferay.Service(

  '/expandovalue/add-value',

  {

    companyId: 101233,

    className: 'com.liferay.portal.model.User',

    tableName: 'CUSTOM_FIELDS',

    columnName: 'Language',

    classPK: 10234,

    data: 'English'

  },

  function(obj) {

    console.log(obj);

  }

);

For adding multiple Values (Here Language and Notification Preferences are custom Fields)

Provide the input to attributeValues as Collection object.

Liferay.Service(

  '/expandovalue/add-values',

  {

    companyId: 101233,

    className: 'com.liferay.portal.model.User',

    tableName: 'CUSTOM_FIELDS',

    classPK: 10234,

    attributeValues: {Language:English, Notification Preference:Email}

  },

  function(obj) {

    console.log(obj);

  }

);

For getting the data (In column Names give the multiple values for getting more than one column data)

Liferay.Service(

  '/expandovalue/get-data',

  {

    companyId: 101233,

    className: 'com.liferay.portal.model.User',

    tableName: 'CUSTOM_FIELDS',

    columnNames: Language, Notification Preference,

    classPK: 10234

  },

  function(obj) {

    console.log(obj);

  }

);
