Customizing FotoWeb 3.0 Example 9: 'Ifnot' tag creating context with 'endif'. In this example, the tag context is executed if current user is not locked out. To evaluate both sides of the condition, you can add the ‘else’ clause as follows: Example 10: 'Ifnot' tag creating double context with 'else' and 'endif'. Conditions are discussed later in this document. 2.3.4 Attributes Some tags allow regulation of information processing by passing parameters to FotoWeb. These parameters are called ‘attributes’ of the tags. These attributes instruct FotoWeb in detail on how to process and/or deliver the information. For example: . . . Example 11: Optional attributes of 'ImageList' tag. In this example ‘rows’, ‘columns’, and ‘archiveId’ are attributes of ‘ImageList’ tag that instruct FotoWeb to produce an image list of archive 5005 with 3 rows and 8 columns. If the rows and columns attributes were not specified, then FotoWeb would use default values of 2 and 6 respectively. These are called optional attributes. Not all attributes are optional. For example: Example 12: Mandatory attributes of 'MathEval' tag. In this example, the attribute ‘expression’ is not optional and must be specified for the ‘MathEval’ tag to produce any sensible information. 2.3.5 Variables Variables are the information access points for the tags and externally set variables. The variables provide textual information that can be added to the final Html transmission to the client. 2.3.5.1 Types of variables The variables can be divided into four categories: 1. Request variables. • These are variables that are passed with the http request. These variables can be accessed anywhere in the page, given they exist. 2. Global variables. • Variables that belong to ‘Global’, ‘CurrentUser’ and ‘BrowserDetection’ tags are called global variables. These variables can be accessed anywhere in the page without calling the tag or creating a tag context. 3. Tag variables. • Variables set by a tag. These variables must be used within the tag’s context. 4. External variables. • Variables that are set manually by the programmer. These variables can be used anywhere in the page after they are set. They behave similar to global variables. 2.3.5.2 Accessing variables 8 / 47 FotoWare
Customizing FotoWeb 3.0 Since the variables return textual values, it is important to know, or at least have an idea of, what type of data you expect from the variables and where it will be used in the Html structure. FotoWeb provides several different options to display and use variable data. These options include: • Html encoding o Encodes the text in Html format for safe display in browsers. • URL encoding o Encodes the text in URL format to construct URLs and query strings. • JavaScript encoding o Encodes the text in JavaScript format to be passed to JavaScript functions. • Plain text encoding o Displays the text as is without any encoding. • Text length capping o Allows capping of the text if it exceeds a specified size. • Text abbreviation o Adds an abbreviation string at the end of the text if it is capped. All these formats can be derived from the ‘InsertVariable’ tag by specifying different attributes. For example: Example 13: Displaying variable with formatting. In this example client’s platform name is being displayed with Html encoding. A maximum of 10 characters will be displayed. If the actual platform name consists of more than 10 characters, then it will be capped down to 10 and the abbreviator string ‘…’ will be appended to it. If no encoding, capping or abbreviation is desired, as may be the case for numerical values, then you can simply retrieve the variable value by directly using the variable name as follows: Example 14: Displaying variables without formatting.
