Having issue with pattern match incorrectly validating in Yii 2
php, regex, yii, yii2
Solution
This pattern only checks first character. You need to correct it like below:
['username', 'match', 'pattern' => '/^[a-zA-Z0-9_-]+$/', 'message' => 'Your username can only contain alphanumeric characters, underscores and dashes.'],
To make sure that Yii's matching is working, you can test it by writing `@` (for example) as first character. Then, you can see that, validation works. So the problem is with your pattern.
Problem
I have a bunch of validation rules within my `rules` method and all the errors seem to work, but having an issue with this one: ``` ['username', 'match', 'pattern' => '/[a-zA-Z0-9_-]+/', 'message' => 'Your username can only contain alphanumeric characters, underscores and dashes.'], ``` It validates, which is the incorrect behavior. Am I doing something wrong here?
