Validation Rule list:

Regex	Regular validation, the defined validation rule is a regular expression (default)
function	function validation, the defined validation rule is a function name
Callback	Method validation, a defined validation rule is a method of the current model class
Confirm	Verify that the two fields in the form are the same, and that the validation rule defined is a field name
Equal	Verify that the value is equal to a value that is defined by the preceding validation rule
NotEqual	Verify that the value is not equal to a value that is defined by the previous validation rule (new in the 3.1.2 version)
Inch	Verifies whether a defined validation rule can be an array or a comma-delimited string within a range
Notin	Verify that the validation rule defined is not within a range, either an array or a comma-delimited string (3.1.2 version added)
Length	Validation length, the defined validation rule can be a number (representing a fixed length) or a range of numbers (for example, 3,12 indicates a range from 3 to 12)
Between	Validation scopes, defined validation rules representing ranges, can use strings or arrays, such as 1,31 or array (1,31)
Notbetween	Validation is not in a range, defined validation rules represent scope, can use strings or arrays (3.1.2 version added)
Expire	Verify that the validation rules defined in the validity period represent a time range that can be used to time, for example, you can use 2012-1-15,2013-1-15 to indicate that the current commit is valid between 2012-1-15 and 2013-1-15, or you can use a timestamp definition
Ip_allow	Verify that IP is allowed, the defined validation rules represent a list of allowed IP addresses, separated by commas, for example 201.12.2.5,201.12.2.6
Ip_deny	Verify that IP is prohibited, the defined validation rules represent a list of forbidden IP addresses, separated by commas, for example 201.12.2.5,201.12.2.6
Unique	Validation is unique, the system will query the database based on the current value of the field to determine if the same value exists, and when the form data contains a primary key field, unique cannot be used to determine the primary key field itself
