Property Details

clientValidate property
public string $clientValidate;

the name of the method that returns the client validation code (See clientValidateAttribute).

method property
public string $method;

the name of the validation method defined in the active record class

params property
public array $params;

additional parameters that are passed to the validation method

Method Details

clientValidateAttribute() method (available since v1.1.9)
public string clientValidateAttribute(CModel $object, string $attribute)
$object CModel the data object being validated
$attribute string the name of the attribute to be validated.
{return} string the client-side validation script.
Source Code: framework/validators/CInlineValidator.php#74 (show)
public function clientValidateAttribute($object,$attribute)
{
    if(
$this->clientValidate!==null)
    {
        
$method=$this->clientValidate;
        return 
$object->$method($attribute,$this->params);
    }
}

Returns the JavaScript code needed to perform client-side validation by calling the clientValidate method. In the client validation code, these variables are predefined:

  • value: the current input value associated with this attribute.
  • messages: an array that may be appended with new error messages for the attribute.
  • attribute: a data structure keeping all client-side options for the attribute
Example:

If clientValidate is set to "clientValidate123", clientValidate123() is the name of the method that returns the client validation code and can look like:
<?php
  public function clientValidate123($attribute,$params)
  {
     if(!isset($params['message']))
        $params['message']='Value should be 123';
     $js = "if(value != '123') { messages.push($params['message']); }";
     return $js;
  }
?>

validateAttribute() method
protected void validateAttribute(CModel $object, string $attribute)
$object CModel the object being validated
$attribute string the attribute being validated
Source Code: framework/validators/CInlineValidator.php#39 (show)
protected function validateAttribute($object,$attribute)
{
    
$method=$this->method;
    
$object->$method($attribute,$this->params);
}

Validates the attribute of the object. If there is any error, the error message is added to the object.
