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.

attributes
