By default in CakePHP 2.0, the authentication component make use of 2 fields to authenticate a user: username & password
If your web application requires user to login using email instead of a username, you can add in the following code snippet in the respective controller:
1 2 3 4 5 6 7 8 | public $components = array( 'authenticate' => array( 'Form' => array( 'fields' => array('username' => 'email') ) ) ) ); |
Take note that $components is a variable instead of a function under a controller.
Explanation: In the above code snippet, the email posted by the form will be taken as the username for the authentication component. The authentication component will then authenticate the user using email when $this->Auth->login() is called.
For more info, please refer to CakePHP 2.0 authentication component.
To check Java Development Kit (JDK) or Java Runtime Environment (JRE) bit version on Windows, open up command prompt and enter the following command:
java -version
If it is 32-bit, you should see something embedded in the version info: Java HotSpot(TM) Client VM
If it is 64-bit, you should see something embedded in the version info: Java HotSpot(TM) 64-bit Server VM
This information is gathered from Java 6. I am not sure this is applicable to Java 7. If anyone knows, please comment.
