Change Login Criteria from Username to email

nellyblissville · February 28, 2016, 7:10pm

I was wondering if its possible to require users to login using their email adress in place of username. Where can I alter the code to change this? any help will be appreciated. thanks

In OJS 2.4.x, replacing the username with the email would be a fairly involved task. You would essentially need to search the entire codebase for one or the other and swap and/or eliminate them.

If you just wanted to enforce that the username was formatted like an email, and still required the entry of a separate (but potentially the same) email, you could do that right on the registration form by changing the validators:

github.com

pkp/ojs/blob/ojs-stable-2_4_8/classes/user/form/RegistrationForm.inc.php#L70-L80


				$this->addCheck(new FormValidatorCustom($this, 'username', 'required', 'user.register.form.usernameExists', array(DAORegistry::getDAO('UserDAO'), 'userExistsByUsername'), array(), true));
				$this->addCheck(new FormValidatorAlphaNum($this, 'username', 'required', 'user.register.form.usernameAlphaNumeric'));
				$this->addCheck(new FormValidatorLength($this, 'password', 'required', 'user.register.form.passwordLengthTooShort', '>=', $site->getMinPasswordLength()));
				$this->addCheck(new FormValidatorCustom($this, 'password', 'required', 'user.register.form.passwordsDoNotMatch', create_function('$password,$form', 'return $password == $form->getData(\'password2\');'), array(&$this)));
				$this->addCheck(new FormValidator($this, 'firstName', 'required', 'user.profile.form.firstNameRequired'));
				$this->addCheck(new FormValidator($this, 'lastName', 'required', 'user.profile.form.lastNameRequired'));
				$this->addCheck(new FormValidatorUrl($this, 'userUrl', 'optional', 'user.profile.form.urlInvalid'));
				$this->addCheck(new FormValidatorEmail($this, 'email', 'required', 'user.profile.form.emailRequired'));
				$this->addCheck(new FormValidatorORCID($this, 'orcid', 'optional', 'user.profile.form.orcidInvalid'));
				$this->addCheck(new FormValidatorCustom($this, 'email', 'required', 'user.register.form.emailsDoNotMatch', create_function('$email,$form', 'return $email == $form->getData(\'confirmEmail\');'), array(&$this)));
				$this->addCheck(new FormValidatorCustom($this, 'email', 'required', 'user.register.form.emailExists', array(DAORegistry::getDAO('UserDAO'), 'userExistsByEmail'), array(), true));
