提问by Arlind
Im working on Laravel 4.2. Im trying to use Validator to validate a name field with regex, here is my rule below:
我正在研究 Laravel 4.2。我试图使用 Validator 用正则表达式验证名称字段，这是我的规则如下：
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:
但是一旦我调用要验证的规则，就会抛出错误，请参见下文：
preg_match(): No ending delimiter '/' found

Since your regex has a pipe in it, you have to use an array:
由于您的正则表达式中有一个管道，因此您必须使用一个数组：
public static $rules_save = [
'class_subjects' => ['required', 'regex:/[0-9]([0-9]|-(?!-))+/'],
];
From the docs:
从文档：
When using the
regexpattern, it may be necessary to specify rules in an array instead of using pipe delimiters, especially if the regular expression contains a pipe character.
使用
regex模式时，可能需要在数组中指定规则而不是使用管道分隔符，尤其是当正则表达式包含管道字符时。
