Description: A form error in web development refers to a problem that occurs during the validation of data entered in a form. This error can arise when the data provided by the user does not meet the validation rules defined in the model or in the form itself. Many web development frameworks offer a robust system for handling forms, which includes automatic data validation. When a form is submitted, the framework checks each field according to the established constraints, such as data types, maximum length, required fields, among others. If any of these criteria are not met, a form error is generated, which can be displayed to the user for necessary corrections. This mechanism not only enhances user experience by providing immediate feedback but also helps maintain data integrity in the database. Form errors are an essential part of web application development, as they allow developers to effectively manage data input and ensure that the information stored is valid and consistent.
