Cfloop over File, Array, List..

2010-03-11T12:49:00.001-08:00

Today while I was working I came across cfloop which I think a cool feature in CF

Cfloop can perform on
>Array
>Collection
>File
>List
>Query and there are some other loops like index loop, condition loop, loop over date and time...

Index Loop:
<cfloop from="1" to="10" index="A"><cfoutput>#A#</cfoutput></cfloop>

Condition Loop:
<cfset Count = 0> here we are setting condition
<cfloop condition = "Count EQ 5">
<cfset CountVar = CountVar + 1>
The loop is <cfoutput>#Count#</cfoutput>
</cfloop>

Query Loop:
<cfquery name = "Q" dataSource = "ABC">
SELECT * FROM TABLE
</cfquery>
<cfloop query = "Q">
<cfoutput>#Name#</cfoutput>
</cfloop>

List Loop:
<cfset B = "Apple, Rose, Car"> Declaring List
<cfloop list="#B#" index="C" delimiters=",">
<cfoutput>#C#</cfoutput>
</cfloop>

Collection/Structure Loop:
<cfset D = StructNew()>
<cfset V = StructInsert(D,"Apple, Rose, Car")>
<cfloop collection="#D#" item="E">
<cfoutput> #StructFind(D ,E)#</cfoutput>
</cfloop

File Loop:

Just loop entire file:

<cfloop file="#File#" index="F">
<cfoutput>#F#</cfoutput>
</cfloop>

First 20 Lines

We can use From and To just as we use in index loop
<cfloop list="#File#" index="F" to="20"> by default from = 1
<cfoutput>#F#</cfoutput>
</cfloop>

In a range say from 50 to 75

<cfloop list="#File#" index="F" From="50" To="75">
<cfoutput>#F#</cfoutput>
</cfloop>

Array Loop:
<cfloop index="M" Array=#G#>
<cfoutput>#M#</cfoutput>
</cfloop>
