ColdFusion Append File
In the previous lesson, we wrote a file to the server using the ColdFusion cffile tag. The cffile tag also allows you to append a file on the server.
To append a file, you simply use action="append" (instead of action="write"). The contents you specify in this tag are appended to the end of the existing file. If the file doesn't already exist, it is created.
Example of Appending a File
This example declares a variable, assigns the current date and time to it, then appends the result to a file.
<cfset dateAccessed = "This page was accessed at this time: " & now()>
<cffile action="append"
file="C:\docs\accessLog.txt"
output="#dateAccessed#">
