 Posted: Thu May 17, 2007 3:46 pm Post subject: Auth 1.5.1 , error handling etc |
 |
|
I'm new to PEAR and after having a look at the Auth package have a few questions.
1.
When using the constructor, something like;
$auth = new Auth(...);
Do you need to wrap in a try / catch block?
Looking at the code in Auth.php there is a possible Exception (throwError), but this is not documented.
| Code: |
/**
* Constructor
*
* Set up the storage driver.
*
* @param string Type of the storage driver
* @param mixed Additional options for the storage driver
* (example: if you are using DB as the storage
* driver, you have to pass the dsn string here)
*
* @param string Name of the function that creates the login form
* @param boolean Should the login form be displayed if neccessary?
* @return void
*/
function Auth($storageDriver, $options = '', $loginFunction = '', $showLogin = true)
{
$this->applyAuthOptions($options);
// Start the session suppress error if already started
if(!session_id()){
@session_start();
if(!session_id()) {
// Throw error
include_once 'PEAR.php';
PEAR::throwError('Session could not be started by Auth, '
.'possibly headers are already sent, try putting '
.'ob_start in the beginning of your script');
}
}
|
2. When using a container (e.g. MDB2) the documentation suggests a return value, but the code doesn't return anything.
| Code: |
/**
* Constructor of the container class
*
* Initate connection to the database via PEAR::MDB2
*
* @param string Connection data or MDB2 object
* @return object Returns an error object if something went wrong
*/
function Auth_Container_MDB2($dsn)
{
$this->_setDefaults();
if (is_array($dsn)) {
$this->_parseOptions($dsn);
if (empty($this->options['dsn'])) {
PEAR::raiseError('No connection parameters specified!');
}
} else {
$this->options['dsn'] = $dsn;
}
}
|
3. What's the easiest way to trap and then use a database connection error for example? The main errors seem to be checked for by the code, but not always returned by the methods. Would I need to set a callback with PEAR::setErrorHandling() to provide my own error handling?
4. Ideally I'd like to write the login/out events to a log file to check for hacking attempts, etc. What would be the best way to do this with PHP and/or PEAR?
Thanks for any suggestions or ideas you may have.

Only a general comment (as I don't have any experience with Auth):

Auth is a PHP 4 package and does not throw exceptions. throwError() "throws" a PEAR_Error object. It isn't returned here (and in your second code snippet), because the lines are located in the constructor. |

Thanks Mark, the error handling makes a bit more sense now. To check for these errors and do something about them I would have to use PEAR::setErrorHandling() or something similar to get access to the error information.
