Incorrect pattern matching in Yii 2

I have a bunch of validation rules in my method rules

and all the errors seem to work, but the problem with this:

['username', 'match', 'pattern' => '/[a-zA-Z0-9_-]+/', 'message' => 'Your username can only contain alphanumeric characters, underscores and dashes.'],

He checks what is the wrong behavior.

Am I doing something wrong here?

This pattern only checks the first character. You need to fix it like below:

['username', 'match', 'pattern' => '/^[a-zA-Z0-9_-]+$/', 'message' => 'Your username can only contain alphanumeric characters, underscores and dashes.'],


To make sure the Yii compliance is working, you can test it by writing @

(for example) as the first character. Then you can see that the validation is working. So the problem is with your template.

The above answer also doesn't work in my project. I am asking you to follow the below solution:



[['userame'],'match', 'pattern' => '/^[a-z]\w*$/i','message' => 'Enter Characters Only'],

All of the above solutions didn't work for me. This is the best thing, so try:

['first_name', 'match', 'pattern' => '/^[a-z][A-Za-z,;\"\\s]+[!?.]$/i'],
