Symfony Regex form validation

Question

I have a form field that I want to match the following rules: at least 3 numbers then at least 7 a-z or A-Z letters, currently I have this but it does not work apparently because I get that my input is not valid even if I respect the rule I mentioned :

->add('NumberAcc', TextType::class, [
            'constraints' => [
                new NotBlank(),
                new Regex('/[0-9]{3,},[a-z]{7,}/')
            ],
        ])

Any ideas? (I know it wont work with Maj letters right now but it doesn't work either with lowercase letters

012,abcdefg matches. Is the comma in the middle a mistake or on purpose? Also, if you want to match uppercase letters too, include A-Z or make it case insensitive. (/[0-9]{3,}[a-z]{7,}/i) — Manfred Radlwimmer

You cannot use Regex for that. My guess is you want a1b2c3d4e5... to be valid as well. Better use Callback constraint then. — Mike Doe

Your regex contains a comma , between the numbers and the letters, which is not in the description of what you are trying to do. Also, if you want to capture both a-z and A-Z you have to explicitly specify it

/[0-9]{3,}[a-zA-Z]{7,}/

or make the regex case insensitive

/[0-9]{3,}[a-z]{7,}/i
