laravel 4.2正则表达式验证

Question

I have rules for password, the rules is:

Only alphanumeric characters, spaces, dashes, periods, and underscores are allowed.

in Users model i use validation like bellow

'password'=>array('required', 'min:8', 'max:20', 'regex:[A-Za-z\s\-\._]')

when the form submitted, it throw error The password format is invalid.. what could be wrong with my regex?

PS: i input 12345678 in password field.

Answer 1

You're not including numerical characters in your regexp.

You should add 0-9, this gives : regex:[A-Za-z0-9\s\-\._]'
