Inconsistent Form::PATTERN about forms

[dg]

Probably you can change (...) to (?:...) as fix.

[MartinSadovy]

I don't think so. There are missing brackets. Pattern is bracketed only in javascript validator.

PR #105

[dg]

To use (?:....) is not possible?

[MartinSadovy]

if you think (?:(.)\1{2,}), answer is no. It is still \2

[dg]

In this case documentation is wrong http://php.net/manual/en/regexp.reference.subpatterns.php

Sorry I don't understand what you mean.

Just here put return (bool) Strings::match($control->getValue(), "\x01^(?:$pattern)\\z\x01u"); and here put return typeof arg === 'string' ? (new RegExp('^(?:' + arg + ')$')).test(val) : null;.

before I create PR, I would like to know, why pattern is bracked.

Because /^abc|def$/ is a different from /^(abc|def)$/.

[MartinSadovy]

Oh, I see. I had understood that I use ?: in pattern (eg. in ->addRule). I did not note (only one pair of breckets), my fault, sorry. O:-)

yeah, now it works correctly.

👍

btw commit message should be changed, isn't it?

[MartinSadovy]

Validator: pattern: supports back reference to Validator: fix different behaviour client and server side while use back reference, is not too long, or actual is ok?
