I want to define the username as 4 letters + 4 digits like "abcd1234". Here is my code in Laravel 5:
public function rules()
{
return [
'username' => 'required|regex:/^[A-Za-z]{4}\d{4}$/|unique:users',
'email' => 'required|email|unique:users',
'password' => 'required|confirmed|min:8'
];
}
However, the regex validation does not work at all. How to solve this problem? Thanks!
The code is correct. The problem is that use App\Http\Requests\Request; is missed in the RegisterRequest.php.
The statements in the RegisterRequest.php should like this :
<?php namespace App\Http\Requests\Auth;
use App\Http\Requests\Request;
class RegisterRequest extends Request {
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'username' => 'required|regex:/^[A-Za-z]{4}\d{4}$/|unique:users',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|min:8|confirmed',
];
}
}
Finally,'username' => 'required|regex:/^[A-Za-z]{4}\d{4}$/|unique:users' works very well !
From doc
regex:pattern
The field under validation must match the given regular expression.
Note: When using the regex pattern, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character.
So, You should do something like this
$rules = array('form_field' => array('required', 'regex:foo'));
[a-zA-Z]{4}\d{4}
[a-zA-Z]{4} means 4 letters \d{4} means 4 digits
