Have A Password With One Uppercase

[FlyAbove]

I am trying to make the password contain one uppercase letter when registering but I am not sure how to do that in PHP. Am I writing the right regex for it?

//password must contain a capital letter

if (preg_match('/((?=.*[A-Z]))/', $pw)) {

array_push($this->errorArray, Constants::$passwordContainCapital);

return;

}

You made it more complicated than it needs to be:

/[A-Z]/

You can also use a regex tester to confirm that it will behave the way you're expecting :)

I was able to solve the issue with this.

if (!preg_match('/[A-Z]/', $pw)) {
       array_push($this->errorArray, Constants::$passwordContainCapital);
        return;
 }
