Im working on Laravel 4.2. Im trying to use Validator to validate a name field with regex, here is my rule below:

 public static $rules_save = [

        'class_subjects' => 'required|regex:/[0-9]([0-9]|-(?!-))+/'
    ];

But as soon as I call the rule to be validated an error is thrown, see below:

preg_match(): No ending delimiter '/' found

Since your regex has a pipe in it, you have to use an array:

public static $rules_save = [
    'class_subjects' => ['required', 'regex:/[0-9]([0-9]|-(?!-))+/'],
];

From the docs:

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.
