} Complete predefined list:

• boolean: Cbooleanvalidator alias. Make sure the attribute value is cbooleanvalidator: truevalue or cbooleanvalidator: falsevalue.
• captcha: The alias of ccaptchavalidator to ensure that the feature value is equal to the Verification code displayed by CAPTCHA.
• compare: The alias of ccomparevalidator to ensure that the feature value is equal to another feature or constant.
• email: The alias of cemailvalidator, which ensures that the feature value is a valid email address.
• default: Cdefavaluvaluevalidator alias, which assigns a default value for the feature.
• exist: The alias of cexistvalidator to ensure that the attribute value exists in the specified data table field.
• file: The alias of cfilevalidator to ensure that the feature contains the name of an uploaded file.
• filter: Cfiltervalidator alias, which uses a filter conversion attribute.
• in: The alias of crangevalidator to ensure that the feature appears in a reserved value list.
• length: The alias of cstringvalidator to ensure that the feature length is within the specified range.
• match: The alias of cregularexpressionvalidator to ensure that the feature matches a regular expression.
• numerical: The alias of cnumbervalidator, which ensures that the feature is a valid number.
• required: The alias of crequiredvalidator to ensure that the feature is not empty.
• type: The alias of ctypevalidator, which ensures that the feature is of the specified data type.

Length: cstringvalidator

In: crangevalidator

1. crequiredvalidator-required value verification attribute

Requiredvalue-mixed-required value

Strict-Boolean-strict or not

Instance: array ('username', 'required'), cannot be empty

Array ('username', 'required', 'requiredvalue '=> 'lh', 'message' => 'usernmae must be LH '), the value must be LH, if you enter another value, the verification will fail.

Array ('username', 'required', 'requiredvalue '=> 'lh', 'strict '=> true ), strict verification can also be followed by 'message' => ", 'on' =>

2. cfiltervalidator filters verification attributes

Filter-method name (call a user-defined function)

Instance:

Array ('username', 'test') function test () {$ username = $ this-> username; if ($ username! = 'Lh ') {$ this-> adderror ('username', 'username must be LH ');}}

If you still write message => in array, the prompt is still in your test. This is based on the error information in test.

3. cregularexpressionvalidator-

Regular Expression verification attribute allowempty-whether it is null (true by default)

Not-whether to reverse the verification logic (default false) pattern-Regular Expression matching instance:

// Match a-Z array ('username', 'match', 'allowempty '=> true, 'pattern' =>'/[A-Z]/I ', 'message' => 'must be a letter '),

// Match is not a-Z array ('username', 'match', 'allowempty '=> true, 'not' => true, 'pattern' => '/[A-Z]/I', 'message' => 'must not be a letter '),

4. cemailvalidator-Email verification attributes:

Allowempty-whether it is null

Allowname-whether the email address name is allowed

Checkmx-whether to check the MX record of the email address

Checkport-whether to check the email address on port 25

Fullpattern-Regular Expression used to verify part of the email address and name

Pattern-Regular Expression,

Example of the property value used for verification: array ('username', 'email ', 'message' =>' must be an email address ', 'pattern' => '/[A-Z]/I '),

5. curlvalidator-URL verification attributes:

Allowempty-whether it is null

Defaultscheme-default URI Scheme

7. ccomparevalidator-comparison verification attributes:

Allowempty-whether it is null

Compareattribute-attributes to be compared

Comparevalue-value of comparison

Operator-comparison operator

Strict-strict verification (values and types must be equal)

Instance: // compare with a value. Array ('username', 'compare', 'comparevalue '=> '10', 'operator' => ', 'message' => 'must be greater than 10 ′),

// Compare it with a submitted attribute array ('username', 'compare', 'companyattribute '= & gt; 'Password', 'operator' => ', 'message' => 'must be greater than password '),
