Called when the menu id is equal to do-regular-login. This happens when the user submits the regular login form using his email and password. In order to authenticate our user we validate if his credentials match.
$id_email = $this->getVariableId('email'); $id_password = $this->getVariableId('password'); $email = strtolower($this->getSubmitVariable($id_email)); $password = sha1(strtolower(trim($this->getSubmitVariable($id_password)))); $saved_email = strtolower($this->getSavedVariable('email')); $saved_password = strtolower($this->getSavedVariable('password'));
We get the submitted email and password using their variable id’s, then we get the email and password stored as variables for the user. Even when the user logs out we still store his id, so when we call the getSavedVariable method, it will take the values for the previously logged user. We check if the submitted values match those stored in the database and we authenticate the user.
Sometimes you may wish to logout and sign in with another account, therefore the stored credentials that are accessed with getSavedVariable won’t match the submitted ones. When this is the case, we use the doLogin() method on the loginmodel. It will attempt to authenticate the user and will return his ID.
If the authentication is successful we call the finishLogin() method on the controller.
