Natively Connect to SAP Ariba Procurement Data in PHP

Drop the CData ODBC Driver for SAP Ariba Procurement into your LAMP or WAMP stack to build SAP Ariba Procurement-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to SAP Ariba Procurement 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.

In order to connect with SAP Ariba Procurement, set the following:

• ANID: Your Ariba Network ID.
• ANID: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Buyer or Supplier API based on your business role (possible values are PurchaseOrdersBuyerAPIV1 or PurchaseOrdersSupplierAPIV1).
• Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

Authenticating with OAuth

After setting connection properties, you need to configure OAuth connectivity to authenticate.

• Set AuthScheme to OAuthClient.
• Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

  For more information on creating an OAuth application, refer to the Help documentation.

Automatic OAuth

After setting the following, you are ready to connect:

APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

When you connect, the provider automatically completes the OAuth process:

1. The provider obtains an access token from SAP Ariba and uses it to request data.
2. The provider refreshes the access token automatically when it expires.
3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

Establish a Connection

Open the connection to SAP Ariba Procurement by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC SAPAribaProcurement 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.

$conn = odbc_pconnect("CData ODBC SAPAribaProcurement Source","user","password");
...
odbc_close($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 Orders WHERE OrderStatus = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC SAPAribaProcurement Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE OrderStatus = ?");
$success = odbc_execute($query, array('CHANGED'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC SAPAribaProcurement Source","user","password");
$query = odbc_exec($conn, "SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'");
 

Process Results

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

$conn = odbc_connect("CData ODBC SAP Ariba Procurement data Source","user","password");
$query = odbc_exec($conn, "SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'");
while($row = odbc_fetch_array($query)){
 echo $row["DocumentNumber"] . "\n";
}

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

$conn = odbc_connect("CData ODBC SAP Ariba Procurement data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Orders WHERE OrderStatus = ?");
$success = odbc_execute($query, array('CHANGED'));
if($success)
 odbc_result_all($query);

More Example Queries

You will find complete information on the driver's supported SQL in the help documentation. The code examples above are SAP Ariba Procurement-specific adaptations of the PHP community documentation for all ODBC functions.
