|
|
* |
354
|
|
|
* This function verifies that all of the various OIDC parameters are |
355
|
|
|
* set in the PHP session. First, the function checks if an OIDC |
356
|
|
|
* client has passed appropriate parameters to the authorization |
357
|
|
|
* endpoint. If so, we call the 'real' OA4MP OIDC authorization |
358
|
|
|
* endpoint and let it verify the client parameters. Upon successful |
359
|
|
|
* return, we call the getClient() function of the dbService to get |
360
|
|
|
* the OIDC client name and homepage for display to the user. All |
361
|
|
|
* client parameters (including the ones passed in) are saved to the |
362
|
|
|
* 'clientparams' PHP session variable, which is encoded as a JSON |
363
|
|
|
* token to preserve arrays. If there are any errors, false is returned |
364
|
|
|
* and an email is sent. In some cases the session variable |
365
|
|
|
* 'client_error_msg' is set so it can be displayed by the |
366
|
|
|
* printOIDCErrorPage() function. |
367
|
|
|
* |
368
|
|
|
* @return bool True if the various parameters related to the OIDC |
369
|
|
|
* session are present. False otherwise. |

Both the

assignment in line 2 are dead. The first because$myVar
is never used and the second because$higher
is always overwritten for every possible time line.
