$this->ModelName->id = $id; $this->ModelName->saveField('fieldName', 'fieldValue');
$record = ModelName::find($id); $record->fieldName = 'fieldValue'; $record->save();The above code retrieves a record with the specified $id, updates the value of the fieldName column to fieldValue, and saves the changes. In conclusion, the saveField method is a useful feature for updating specific fields in database tables in Model classes of MVC applications. The examples above were implemented in CakePHP and Laravel frameworks, respectively.
