ColdFusion Programming/control structures

As in most programming languages Coldfusion includes control structures to help your program be more useful. CFIF The most basic control structure is the CFIF. It works exactly like an If statement in other programming languages. A sample CFIF statement would look like this: <cfif 2 gt 1> First <cfelse> Second </cfif> The result would be: First CFSWITCH Like with other programming languages Coldfusion provides a switch functionality. Sample CFSWITCH: <cfswitch expression="bob"> <cfcase value="george"> George </cfcase> <cfcase value="bob"> Bob </cfcase> </cfswitch> The result would be: Bob CFLOOP Index Loop: Attributes from - starting number to - ending number index - value within the loop step - optional (default 1) - change to make with each iteration Example: <cfloop from="1" to="9" index="i"> #i# </cfloop> Results: 1 2 3 4 5 6 7 8 9 <cfloop from="1" to="9" index="i" step="2"> #i# </cfloop> Results: 1 3 5 7 9 Conditional Loop: Attributes condition - continue looping as long as condition is true Example: <cfset i = 2> <cfloop condition="i lt 10"> #i# <cfset i = i + 2> </cfloop> Results: 1 3 5 7 9 Query Loop: Attributes query - query name you want to loop through startrow - optional(default 1) - row to begin with endrow - optional(default last) - row to end with Query getpeople looks like this: Age Name 10 Bill 25 Martha 30 Judy Example: <cfloop query="getpeople"> #Age#, #Name# </cfloop> Results: 10, Bill 25, Martha 30, Judy List Loop: Attributes index - variable to hold element of list list - list to go through delimiters - optional (default ,) - separator used to break list apart List people looks like this: (Bill,Martha,Judy) Example: <cfloop list="people" index="i"> #i#! </cfloop> Results: Bill! Martha! Judy! Collection Loop: Attributes collection - structure name you want to loop through item - variable to hold element of structure Structure place looks like this: Zip Name 55057 Northfield Example: <cfloop collection="#place#" item="i"> <cfoutput>#i#-#place[i]#</cfoutput>, </cfloop> Results: Zip-55057, Name-Northfield
