Validating the file field

The HTML form we will be working at in these chapters, contains various input fields: required and optional text fields, radio buttons, and a submit button: The validation rules for the form above are as follows: This code adds a script tag and an alert command.

Remember that a Java bean must have a default no-argument constructor and public getters and setters for all exposed properties.

Thrown when the underlying input stream is malformed based on the configured stream format, and therefore a record could not be accurately read from the stream.

If a message is not configured under the name of the first key, the next key will be tried until a message is found, or a default message is used.

Bean IO supports several common field validation rules when reading an input stream.

These pages will show how to process PHP forms with security in mind.

Proper validation of form data is important to protect your form from hackers and spammers!

The following example illustrates some of the ways a template can be used: configurations bound to the bean.

Let's suppose we are reading a CSV input file of orders that contains an order, followed by the customer that placed the order, followed by a detailed list of items that make up the order.

If the stream layout does not strictly enforce record sequencing, further reads from the input stream are likely to be successful.
