  • required 判断字段对应的值是否是对应类型的零值
  • integer、array、string 表示字段类型是否是整数类型,如果integer后边不接=?,?,那么表示只判断是否是整数类型,如果后边接=?,?,那么有四种写法
    • (1). integer=10 表示字段值 = 10
    • (2). integer=_ ,10 表示字段值 <= 10,字段值最小值为字段对应类型的最小值(比如字段对应类型为int8,那么最小为−128),最大值为10
    • (3). integer=10, _ 表示字段值 >= 10,字段值最小值为10,最大值为字段对应类型的最大值(比如字段对应类型为int8,那么最大为127)
    • (4). integer=1,20 表示字段值 >=1 并且 <= 20
  • mail 表示字段值是否是合法的email地址
  • url 表示字段值是否是合法的url地址
  • in 表示字段值在in指定的值中,比如 Hobby 字段中,in=swimming,running,drawing,表示 Hobby 字段的值,只能swimming,running,drawing中的一个或多个
  • datetime 表示字段值符合日期类型,如果datetime后边不接=?,那么默认为Y-m-d H:i:s,否则验证器会按照指定格式判断,比如 datetime=Y-m、datetime=Y/m/d H:i:s等,可以是Y m d H i s 的随意拼接
  • unique 表示字段值唯一,比如 Hobby 字段的 unique,表示 Hobby 字段值唯一,Class 中,Cname 字段的 unique,表示 Cname 字段值唯一
  • valid:"matches(^1[3-9]{1}\\d{9}$)" 正则匹配
