Build a Simple VCL Application for WooCommerce Data

How to build a simple VCL Application to view WooCommerce data in RAD Studio using the CData FireDAC Components for WooCommerce.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for WooCommerce, you gain access to live WooCommerce data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to retrieve and update WooCommerce data. This article will walk through connecting to WooCommerce and creating a simple VCL application with the Form Designer.

Creating a VCL Application for WooCommerce Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to WooCommerce from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysWooCommerceDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.WooCommerce" in the DriverId menu and configure the connection properties.

    WooCommerce supports the following authentication methods: one-legged OAuth1.0 Authentication and standard OAuth2.0 Authentication.

    Connecting using one-legged OAuth 1.0 Authentication

    Specify the following properties (NOTE: the below credentials are generated from &service; settings page and should not be confused with the credentials generated by using WordPress OAuth2.0 plugin):

    • ConsumerKey
    • ConsumerSecret

    Connecting using WordPress OAuth 2.0 Authentication

    After having configured the plugin, you may connect to WooCommerce by providing the following connection properties:

    • OAuthClientId
    • OAuthClientSecret
    • CallbackURL
    • InitiateOAuth - Set this to either GETANDREFRESH or REFRESH

    In either case, you will need to set the Url property to the URL of the WooCommerce instance.

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
