username validation

I want this rules for my username field:

only a-z or A-Z
0-9
underscore and dash, But should not use in start or end, Also should use only one time in word

Not valid :

__name-----

name____-----

user_____name

Valid : 

user-name
user_name

I found laravel alpha_dash helpful for this, But the problem is, it allows multiple dash and underscore also in start and end, I know we can handle this with regex but is there any quick and laravel way ?

Use regex in your validation rule.

I think this one should do the trick

'user' => 'regex:/^([a-z])+?(-|_)([a-z])+$/i'
