cfloop: looping over a list or file

Description

Looping over a list steps through elements contained in any of these entities:

• A variable
• A value that is returned from an expression
• A file

Syntax

<cfloop 
  index = "index_name"
  list = "list_items"
  delimiters = "item_delimiter">
  ...
</cfloop>

cfabort, cfbreak, cfexecute, cfexit, cfif, cflocation, cfswitch, cfthrow, cftry

Attributes

Attribute	Req/Opt	Default	Description
index	Required		In a list loop, the variable to receive next list element.
list	Required		A list, variable, or file name; contains a list
delimiters	Optional		Character(s) that separates items in list

Example

This loop displays four names:

<cfloop index = "ListElement" 
  list = "John,Paul,George,Ringo"> 
    <cfoutput>#ListElement#</cfoutput><br> 
</cfloop>

You can put more than one character in the delimiters attribute, in any order. For example, this loop processes commas, colons, and slashes as list delimiters:

<cfloop index = "ListElement" 
  list = "John/Paul,George::Ringo" 
  delimiters = ",:/"> 
    <cfoutput>#ListElement#</cfoutput><br> 
</cfloop>

ColdFusion skips the second and subsequent consecutive delimiters between list elements. Thus, in the example, the two colons between "George" and "Ringo" are processed as one delimiter.

To loop over each line of a file, use the tag this way:

<cfloop list="#theFile#" 
  index="curLine" 
  delimiters="#chr(10)##chr(13)#"> 
  ...
</cfloop>
