Validate Email using Validator of Cakephp3

Let's assume you need to validate an email that is not a part of model Entity. If it was a field in model, the validation rules in model would have taken care of it. But in this case, you need to validate the email address yourself. So, what will you use? A regex ? No, instead you can use the Validation class of Cake.

So, How do we validate an email in cakephp3 using it's validator?

It's simple :

First insert the below line in your controller or Model :

use Cake\Validation\Validation;

This will include the validation class in your file.

Now use the below line in your function :

$check=Validation::email('email to be validated');

If $check is true, then it's a valid email else the email is invalid.
