Validating input entails more than just checking whether a phone number is formatted correctly or if a user needs help based on what was typed in a form field. It is also a way to ensure you are accepting only the data you expect. What if you expect to get an address and instead you get something like DELETE * from products This is called SQL injection. You will want a way to filter out SQL commands before the statement is sent to your server and potentially executed. One way to handle SQL injection is to create parameterized queries that do not take plain-text entries. That way, you are never uncritically executing a query sent from a client application. Many Flex applications take data entry through TextInput, TextArea, Text, or even DataGrid components. These controls open up the system to potential attacks. It is up to you to program the inputs so that malicious characters cannot be entered into your application. One way to reduce the risk of bad data input is to use the Flex validators. These help to specify what can and cannot be typed into an input control. Flex provides several validators, such as StringValidator, PhoneNumberValidator, DateValidator, and CreditCardValidator. These provide a more secure means of data capture and should be used when you are building a Flex application exposed to the Internet or for general usage.

The $user object now has a permanent attribute: global $user; print $user->disposition;

Then when creating your GTileLayer objects for each image, pass copyrights into the tile layer as the first parameter to the GTileLayer class: var BlueMarbleCloudyTiles = new GTileLayer(copyrights,0,5); When your map loads, you should be able to see the credit in the copyright information in the lower-right corner of the map, as shown in Figure 9-26.

In traditional settings, much of the data validation occurs on the server. I am an advocate of keeping your business logic on the server, even though Flex is quite capable of doing all data validation. That being said, there are advantages to allowing Flex to validate data before it is shipped to the server. You do not need to handle errors returned from the server, and by validating data in Flex, you will process fewer transactions on server-side resources. This helps to create a more responsive application, which will please your end users. Another approach to securing input characters in Flex is to create ActionScript filters to remove potentially harmful characters before they are sent to a server. Characters you will want to strip out are those that have meaning in a programming language or system, such as the following: Semicolon (;) Apostrophe (') Dollar sign ($) Quotation mark (") Flex can also render HTML in controls. Before you save characters in an HTML input control, you should convert the following characters to limit exposure to malicious HTML injection: Left and right brackets (< >); translate to < and > Left and right parentheses (( )); translate to ( and ) Pound sign (#); translates to # Ampersand (&); translates to &

While this approach is convenient, it creates additional overhead when the user logs in and the $user object is instantiated, since any data stored in this way must be unserialized. Thus, throwing large amounts of data willy-nilly into the $user object can create a performance bottleneck. An alternate and preferred method, in which attributes are added to the $user object when the object is loaded, is discussed shortly.
