Laravel在表单验证器中有一个exists修饰符？

Question

$validator = Validator::make($post,
    array(

        'f_name' => 'required|min:7',
        'l_name' => 'required|min:7',
        'login' => 'required|unique:users|min:7'
    )
);

有什么可以检查记录是否存在吗？

类似的东西：

'login' => 'required|min:|exists:users'

Answer 1

是的，语法为exists:table,column。例如：

$validator = Validator::make($post, array(
    'f_name' => 'required|min:7',
    'l_name' => 'required|min:7',
    'login'  => 'required|min:7|exists:users,login'
));
