Wordpress JDBC Driver

Provides Java developers with the power to easily connect their Web, Desktop, and Mobile applications to data in Wordpress Pages, Posts, Tags, Users, and more!



Write standard ColdFusion data access code to connect to WordPress data.

The CData JDBC Driver for WordPress seamlessly integrates connectivity to WordPress data with the rapid development tools in ColdFusion. This article shows how to connect to WordPress data in ColdFusion and query WordPress tables.

Create a JDBC Data Source for WordPress in ColdFusion

The JDBC data source enables you to execute SQL from standard ColdFusion tags like cfquery and CFScript like executeQuery.

  1. Copy the driver JAR and .lic file from the installation directory onto the ColdFusion classpath. For example, copy the files into C:\MyColdFusionDirectory\cfusion\wwwroot\WEB-INF\lib. Or, open the Java and JVM page in the ColdFusion Administrator and enter the path to the files in the ColdFusion Class Path box.

    The JAR and license for the driver are located in the lib subfolder of the installation directory.

    Restart the server after this step.

  2. Add the driver as a data source:

    From the ColdFusion administrator interface, expand the Data & Services node and click Data Sources. In the Add New Data Source section, enter a name for the data source and select Other in the Driver menu.

  3. Populate the driver properties:

    • JDBC URL: Enter connection properties in the JDBC URL. The JDBC URL begins with jdbc:wordpress: and is followed by the connection properties in a semicolon-separated list of name=value pairs.

      To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth you will need to register an app with WordPress.

      See the Getting Started guide in the CData driver documentation for more information.

      Built-in Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the WordPress JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.wordpress.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      A typical JDBC URL is below:

      jdbc:wordpress:Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH
    • Driver Class: Enter the driver class. The driver class is cdata.jdbc.wordpress.WordPressDriver.
    • Driver Name: Enter a user-defined name for the driver.
    • Username: Enter the username used to authenticate.
    • Password: Enter the password used to authenticate.

You can now test the connection by enabling the CData WordPress data source in the Actions column. After reporting a status of OK, the WordPress data source is ready for use.

Execute Queries

The cfquery tag can pass SQL statements to WordPress, including INSERT, UPDATE, and DELETE.. Use the cfqueryparam tag to create parameterized queries and prevent SQL injection through the query string.

<cfquery name="WordPressQuery" dataSource="CDataWordPress"> SELECT * FROM Categories WHERE Id = <cfqueryparam value="#Id#" cfsqltype="cf_sql_varchar"> </cfquery> <cfdump var="#WordPressQuery#">

Below is the equivalent in CFScript:


<cfscript>
result = queryExecute(
  "SELECT * FROM Categories WHERE Id = ?", 
  [
    { value="1", cfsqltype="cf_sql_varchar" }
  ],
  { datasource="CDataWordPress" }
);

writeDump( var= result );
</cfscript> 

You can then make requests to your .cfm like the following:

http://MyServer:8500/query.cfm?Id=1
