In addition to managing files on the server, you can use cffile
to read, create, and modify text files. As a result, you can do the following things:
cflog
to create and write to log files.)You can use cffile
to read an existing text file. The file is read into a local variable that you can use anywhere in the application page. For example, you could read a text file and then insert its contents into a database, or you could read a text file and then use one of the string replacement functions to modify the contents.
<html> <head> <title>Read a Text File</title> </head> <body> Ready to read the file:<br> <cffile action="read" file="C:\inetpub\wwwroot\mine\message.txt" variable="Message"> <cfoutput> #Message# </cfoutput> </body> </html>
You can use cffile
to write a text file based on dynamic content. For example, you could create static HTML files or log actions in a text file.
<html> <head> <title>Put Information into a Text File</title> </head> <body> <h2>Put Information into a Text File</h2> <form action="writetextfileaction.cfm" method="Post"> <p>Enter your name: <input type="text" name="Name" size="25"></p> <p>Enter the name of the file: <input type="text" name="FileName" size="25">.txt</p> <p>Enter your message: <textarea name="message"cols=45 rows=6></textarea> </p> <input type="submit" name="submit" value="Submit"> </form> </body> </html>
.
Note: The form will not work until you write an action page for it (see the next procedure).
<html> <head> <title>Write a Text File</title> </head> <body> <cffile action="write" file="C:\inetpub\wwwroot\mine\#Form.FileName#.txt" output="Created By: #Form.Name# #Form.Message# "> </body> </html>
The text file is written to the location you specified. If the file already exists, it is replaced.
You can use cffile
to append additional text to the end of a text file; for example, when you create log files.
action
attribute from write
to append
so that the file appears as follows:
<html> <head> <title>Append a Text File</title> </head> <body> <cffile action="append" file="C:\inetpub\wwwroot\mine\message.txt" output="Appended By: #Form.Name#"> </body> </html>
The appended information displays at the end of the text file.
