Natively Connect to SAP Ariba Source Data in PHP

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

• API: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Supplier, Sourcing Project Management, or Contract API based on your business role (possible values are SupplierDataAPIWithPaginationV4, SourcingProjectManagementAPIV2, or ContractAPIV1).
• DataCenter: The data center where your account's data is hosted.
• Realm: The name of the site you want to access.
• Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

If you are connecting to the Supplier Data API or the Contract API, additionally set the following:

• User: Id of the user on whose behalf API calls are invoked.
• PasswordAdapter: The password associated with the authenticating User.

If you're connecting to the Supplier API, set ProjectId to the Id of the sourcing project you want to retrieve data from.

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 Source by calling the or methods. To close connections, use or .

$conn = odbc_connect("CData ODBC SAPAribaSource 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.

$conn = odbc_pconnect("CData ODBC SAPAribaSource Source","user","password");
...
odbc_close($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 Vendors WHERE Region = ?");

Execute Queries

Execute prepared statements with .

$conn = odbc_connect("CData ODBC SAPAribaSource Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Vendors WHERE Region = ?");
$success = odbc_execute($query, array('USA'));
 

Execute nonparameterized queries with .

$conn = odbc_connect("CData ODBC SAPAribaSource Source","user","password");
$query = odbc_exec($conn, "SELECT SMVendorID, Category FROM Vendors WHERE Region = 'USA'");
 

Process Results

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

$conn = odbc_connect("CData ODBC SAP Ariba Source data Source","user","password");
$query = odbc_exec($conn, "SELECT SMVendorID, Category FROM Vendors WHERE Region = 'USA'");
while($row = odbc_fetch_array($query)){
 echo $row["SMVendorID"] . "\n";
}

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

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