What is coldfusion?

• The ColdFusion Web application server provides
  the fastest way to integrate browser, server, and
  database technologies into powerful Web
  applications and interactive Web sites.
• ColdFusion templates, look surprisingly similar
  to standard HTML pages, but the difference is
  that you can create a single template and serve
  up tons of information dynamically rather than
  having to create a separate page for every item.
• ColdFusion applications rely on these core
  development components
• The ColdFusion Markup Language (CFML)
• ColdFusion Server
• ColdFusion Administrator

CFML

• The ColdFusion Markup Language (CFML) consists
  of a set of tags you use in your ColdFusion pages
  to interact with data sources, manipulate data,
  and display output.
• ColdFusion Express supports a subset of CFML.
  Using CFML tags is very simple tag syntax is
  much like HTML element syntax.
• lets examplify and look into the tags and
  functions provided by CFML

CFML example

• ltHTMLgt
• ltHEADgt
• ltTITLEgtArrayAppend Examplelt/TITLEgt
• lt/HEADgt
• ltBODYgt
• ltH3gtArrayAppend Examplelt/H3gt
• ltCFQUERY NAME"GetEmployeeNames"
  DATASOURCE"HRApp"gt
• SELECT FirstName, LastName FROM Employees
• lt/CFQUERYgt
• lt! Simplicity of expressing the query gt

5

• lt!--- create an array ---gt
• ltCFSET myArrayArrayNew(1)gt
• lt!--- set element one to show where we are ---gt
• ltCFSET myArray1"Test Value"gt
• lt!--- loop through the query and append these
  names successively to the last element ---gt
• ltCFLOOP query"GetEmployeeNames"gt
  ltCFOUTPUTgtArrayAppend(myArray, "FirstName
  LastName")
• lt/CFOUTPUTgt, Array was appendedltBRgt
• lt/CFLOOPgt

6

• lt!--- show the resulting array as a list ---gt
• ltCFSET myListArrayToList(myArray,",")gt
• lt!--- output the array as a list ---gt
  ltCFOUTPUTgt
• ltPgtThe contents of the array are as
  followsltPgtltbgtmyListlt/bgt
• lt/CFOUTPUTgt
• lt/BODYgt
• lt/HTMLgt

7

• In the above eg . CFQUERY
• passes the query name "GetEmployeeNames" to
• be applied to datasource Hrapp
• CFLOOP has several forms
• --loop based on condition
• --loop on index
• --loop on query (used in above eg.)
• Note the syntax for usage of function
  ArrayAppend which takes 2 args arrayname and
  value to be appended

variables

CFML TAGS

• CFABORT
• Stops processing of a ColdFusion page at the
  tag location.
• CFAPPLICATION
• Defines application name and activates client
  variables.
• CFBREAK
• Breaks out of a CFML looping construct.
• CFCOOKIE
• Defines and sets cookie variables.
• CFIF CFELSEIF CFELSE
• Used to create IF-THEN-ELSE constructs.

10
CFML TAGS (conti)

• CFINCLUDE
• Embeds references to ColdFusion pages.
• CFINSERT
• Inserts records in an ODBC data source.
• CFLOCATION
• Opens a ColdFusion page or HTML file.
• CFLOOP
• Repeats a set of instructions based on set of
  conditions.
• CFPARAM
• Defines a parameter and its initial default
  value.

11
CFML TAGS (conti)

• CFOUTPUT
• Displays output of database query or other
  operation
• CFQUERY
• Passes SQL to a database.
• CFSET
• Defines a variable.
• CFSETTING
• Define and control a variety ColdFusion
  settings.

12
CFML TAGS (conti)

• CFSWITCH CFCASE CFDEFAULTCASE
• Evaluates a passed expression and passes
  control to the CFCASE tag that matches the
  expression result.
• CFUPDATE
• Updates rows in a database data source

13
CFML FUNCTIONS

• Array Functions
• Date and Time Functions
• Decision Functions
• Display and Formatting Functions
• Dynamic Evaluation Functions
• List Functions
• Mathematical Functions
• Query Functions
• String Functions
• Structure Functions
• System Functions

14
Cold fusion server

• When any ColdFusion Server is installed on a Web
  serverThe Web server passes files to ColdFusion
  Server if a page request contains a ColdFusion
  file extension.
• ColdFusion Server scans the page and processes
  all CFML tags. ColdFusion Server then returns
  only HTML and other client-side technologies to
  the Web server and, in turn, the browser.

15
COLDFUSION ADMINISTRATOR

• You use the Administrator to perform a variety of
  administrative tasks for the ColdFusion Server,
  such as adding and configuring a data source and
  configuring security settings.
• During the ColdFusion installation process,
  you specify an Administrator password that is
  used to prevent unauthorized access to the
  Administrator pages.
• Open the administrator by loading the following
  URL http//hostname/CFIDE/administrator/index.cfm
  

16
The admin facilities include..

• Starting and Stopping ColdFusion
• The Settings Page
• Configuring Administrator Security
• Mapping Directories
• The ColdFusion Logging Page
• ColdFusion Administrator Debugging Options

17
CONCLUSION

• There are lot more facilities which assist in
• ColdFusion Studio helps in developing templates.
• building search interfaces for database
• building webfront ends for online database
  manipulation .
