Natively Connect to Aha Data in PHP
The CData ODBC driver for Aha enables you to create PHP applications with connectivity to Aha data. Leverage the native support for ODBC in PHP.
Drop the CData ODBC Driver for Aha into your LAMP or WAMP stack to build Aha-connected Web applications. This article shows how to use PHP's ODBC built-in functions to connect to Aha 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.
Start by setting the Profile connection property to the location of the Aha! Profile on disk (e.g. C:\profiles\aha.apip). Next, set the ProfileSettings connection property to the connection string for Aha! (see below).
Aha! API Profile Settings
The Aha! API uses OAuth-based authentication.
You will first need to register an OAuth app with Aha!. This can be done from your Aha! account under 'Settings' > 'Personal' > 'Developer' > 'OAuth Applications'. Additionally, you will need to set the Domain, found in the domain name of your Aha account. For example if your Aha account is acmeinc.aha.io, then the Domain should be 'acmeinc'.
After setting the following in the connection string, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the client_id that is specified in you app settings.
- OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
- Domain: Set this in the ProfileSettings to your Aha domain.
Establish a Connection
Open the connection to Aha by calling the odbc_connect or odbc_pconnect methods. To close connections, use odbc_close or odbc_close_all.
$conn = odbc_connect("CData ODBC API Source","user","password");
Connections opened with odbc_connect are closed when the script ends. Connections opened with the odbc_pconnect 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.
$conn = odbc_pconnect("CData ODBC API Source","user","password");
...
odbc_close($conn); //persistent connection must be closed explicitly
Create Prepared Statements
Create prepared statements and parameterized queries with the odbc_prepare function.
$query = odbc_prepare($conn, "SELECT * FROM Ideas WHERE AssignedToUserId = ?");
Execute Queries
Execute prepared statements with odbc_execute.
$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Ideas WHERE AssignedToUserId = ?");
$success = odbc_execute($query, array('my_user_id'));
Execute nonparameterized queries with odbc_exec.
$conn = odbc_connect("CData ODBC API Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Ideas WHERE AssignedToUserId = 'my_user_id'");
Process Results
Access a row in the result set as an array with the odbc_fetch_array function.
$conn = odbc_connect("CData ODBC Aha data Source","user","password");
$query = odbc_exec($conn, "SELECT Id, Name FROM Ideas WHERE AssignedToUserId = 'my_user_id'");
while($row = odbc_fetch_array($query)){
echo $row["Id"] . "\n";
}
Display the result set in an HTML table with the odbc_result_all function.
$conn = odbc_connect("CData ODBC Aha data Source","user","password");
$query = odbc_prepare($conn, "SELECT * FROM Ideas WHERE AssignedToUserId = ?");
$success = odbc_execute($query, array('my_user_id'));
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 Aha-specific adaptations of the PHP community documentation for all ODBC functions.
