About the file rule, there are several rules. Some rules apply to “types”, “allowEmpty”, “maxSize”,. So how can you customize messages for a file rule? A rule can be used to validate one or more attributes, and an attribute can be validated by one or more rules. A rule can only be applied in certain scenarios if the on option is specified. If you do not specify an on option, the rule is applied to all scenarios. If you need to perform multiple validations on multiple values, you can use [[yiibaseDynamicModel]], which supports hot declaration of attributes and rules. The usage is as follows: The most important validation rules are − boolean, captcha, compare, date, default, double, each, email, exist, file, filter, image, ip, in, integer, match, number, required, safe, string, trim, unique, url. The text was updated successfully, but the following errors occurred: public string $tooBig = null Custom error message used when the value is greater than $max. I want to specify a minimum for a numeric field AND display a custom error message if that minimum is not met. How do I proceed? Yii2.0 provides support for this data validation and it is also a very easy way to test input data.
To validate() the input data, we must declare the validation rules for the attributes you want to validate. Rules must be an array and be returned to the base class of [[yiibaseModel::validate()]]. Each rule must have at least one attribute. We can create new custom rules based on our business criteria. We have added the Yiiframework 2.0 validation list I have the following rules in my template. The problem is that the custom error message does not appear. Instead, the default message is displayed. Do you have any idea why? I appreciate any help. For the validate() function to work, you must override the yiibaseModel::rules() method.
As you can see, `max` for `min` = > 6 displays the default message. I expected my own message from my own rule. For validate() to really work, you must declare validation rules for the attributes you want to validate. To do this, replace the [[yiibaseModel::rules()]] method. The following example shows how to declare validation rules for the ContactForm template: Many core validation controls support standard client-side validation. All you have to do is simply use [[yiiwidgetsActiveForm]] to create your HTML forms. For example, LoginForm declares two rules below: one uses the required base validator, which is supported on both the client and server-side sides; the other uses the validatePassword online validator, which is only supported on the server side. I have the same problem as I have the following rules for the phone [[`phone`,`ci_mobileno`, `trainer_mobile`], `string`,`min` = >10, `max` = > 10,`message` = >`Should be 10 digits long.( For example, 9012687986)`], but it displays the following message Phone must be at least 10 characters long. By default, an entry is considered empty if its value is an empty string, an empty array, or a null value. You can customize the default empty detection logic by configuring the [[yiivalidatorsValidator::isEmpty]] property with a callable PHP.
Example: What about the attribute value? These are standard error messages. Shouldn`t there be a {value}? The HTML form created from the following code contains two input fields, User Name and Password. If you submit the form without typing anything, error messages asking you to enter will appear immediately without communication with the server. If you need to perform asynchronous client-side validation, you can create deferred objects. For example, to perform custom AJAX validation, you can use the following code: You should never trust data received from users. To validate a model with user input, you must call the yiibaseModel::validate() method. It returns a Boolean value if validation succeeds. If errors occur, you can retrieve them from the yiibaseModel::$errors property. According to the validation steps above, an attribute is only validated if it is an active attribute declared in scenarios() and associated with one or more active rules declared in rules(). The default encoding errorOptions is true, so your HTML is encoded as a message, so it won`t work until you set `encode` = > false. In the login form, the glyphicon-remove icon should appear at the end of each validation message with the corresponding field names. So I used the following code in the connection model.
Some validators may support additional error messages to describe various causes of validation errors in more detail. For example, the validator supports [[yiivalidatorsNumberValidator|number]] [[yiivalidatorsNumberValidator::tooBig|tooBig]] and [[yiivalidatorsNumberValidator::tooSmall|tooSmall]] to describe the validation error if the value to be validated is too large or too small. You can configure these error messages as a configuration of other validator properties in a validation rule. After validation, you can check whether the validation was successful or not by calling the [[yiibaseDynamicModel::hasErrors()|hasErrors()]] method, and then retrieving the validation errors from the [[yiibaseDynamicModel::errors|errors]] property], as you do with a normal model. You can also access dynamic attributes defined by the model instance, such as $model > name and $model> email.
