 Q:

Symfony2 - How to validate an email address in a controller

There is an email validator in symfony that can be used in a form: http://symfony.com/doc/current/reference/constraints/Email.html
My question is: How can I use this validator in my controlelr in order to validate an email address?
This is possible by using the PHP preg_match for usere, but my question is if there is a possibility to use the Symfony already built in email validator.
Thank you in advance.

A:

By using validateValue method of the Validator service
use Symfony\Component\Validator\Constraints\Email as EmailConstraint;
//...

public function customAction()
{
    $email = 'value_to_validate';
    //...

    $emailConstraint = new EmailConstraint();
    $emailConstraint->message = 'Your customized error message';

    $errors = $this->get('validator')->validateValue(
        $email,
        $emailConstraint 
    );

    // $errors is then empty if your email address is valid
    // it contains validation error message in case your email address is not valid
    //...
}
//...

It also covers a common bug where you validate against Email Constraint and forget about NotBlank
/**
 * Validates a single email address (or an array of email addresses)
 *
 * @param array|string $emails
 *
 * @return array
 */
new file or pipe is created that will capture the resultant role.   The fact that the arrow is target left < () instead of > () means that the output signal from the inner process will be write to the file, which can be read by the process.  
 In your event, bash < < (...) will be seen as something like bash < /dev / fd/100
