Need to create complex rules by calling multiple providers. Providers: The complete list of rule provider objects, useful if you The second is a context arrayĬontaining data related to the validation process:ĭata: The original data passed to the validation method, useful if you Will be the value for the field being validated. Use a global function $validator -> add ( 'title', 'custom', ) // Use an array callable that is not in a provider $validator -> add ( 'title', 'custom', , 'message' => 'The title is not valid' ]) // Use a closure $extra = 'Some additional value needed inside the closure' $validator -> add ( 'title', 'custom', ) // Use a rule from a custom provider $validator -> add ( 'title', 'custom', ) Ĭlosures or callable methods will receive 2 arguments when called. See the Conditional Validation section for examples onĪn example of these methods in action is:
#Validation check update
Update The field can be empty when validating an updateĪ callback that returns true or false to indicate whether a field isĪllowed to be empty. The allowEmpty* methods support a when parameter that allows you to controlįalse The field is not allowed to be empty.Ĭreate The field can be empty when validating a create Specific validators instead: notEmptyString(), notEmptyArray(), notEmptyFile(), notEmptyDate(), notEmptyTime(), notEmptyDateTime(). In general, it is recommended that you do not use notEmpty() and use more You can also use notEmpty() to mark a field invalid if any ‘empty’ value is

You can either add rules individually or in groups as seen above. The add() method allows you to add new rules toĪ validator. There were a few methods called in the example above, so let’s go over the $validator -> requirePresence ( 'title' ) -> notEmptyString ( 'title', 'Please fill this field' ) -> add ( 'title', , 'message' => 'Titles need to be at least 10 characters long', ] ]) -> allowEmptyDateTime ( 'published' ) -> add ( 'published', 'boolean', ) -> requirePresence ( 'body' ) -> add ( 'body', 'length', , 'message' => 'Articles must have a substantial body.' ]) Īs seen in the example above, validators are built with a fluent interface thatĪllows you to define rules for each field you want to validate.

Prior to 3.7 you must use allowEmpty() or notEmpty().
