Natively Connect to WordPress Data in PHP

Drop the CData ODBC Driver for WordPress into your LAMP or WAMP stack to build WordPress-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to WordPress data, execute queries, and output the results.

Configure a DSN

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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 register an app with WordPress.

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

Establish a Connection

Open the connection to WordPress by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC WordPress Source","user","password");

Connections opened with are closed when the script ends. Connections opened with the method are still open after the script ends. This enables other scripts to share that connection when they connect with the same credentials. By sharing connections among your scripts, you can save system resources, and queries execute faster.

$conn = odbc_pconnect("CData ODBC WordPress Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly

Create Prepared Statements

Create prepared statements and parameterized queries with the function.

$query = odbc_prepare($conn, "SELECT * FROM Categories WHERE Id = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC WordPress Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Categories WHERE Id = ?");
$success = odbc_execute($query, array('1'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC WordPress Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Categories");
 

Process Results

Access a row in the result set as an array with the function.

$conn = odbc_connect("CData ODBC WordPress data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Categories");
while($row = odbc_fetch_array($query)){
 echo $row["Id"] . "\n";
}

Display the result set in an HTML table with the function.

$conn = odbc_connect("CData ODBC WordPress data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Categories WHERE Id = ?");
$success = odbc_execute($query, array('1'));
if($success)
 odbc_result_all($query);
