我正在研究Laravel 4.2.我正在try 使用Validator验证带有正则表达式的名称字段，下面是我的规则:
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:
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.
