220 Developing Web Applications with ColdFusion
Using CFFILE
The CFFILE tag gives you the ability to work with files on your server in a number of
ways:
• Uploading files from a client to the Web server using an HTML form.
• Moving, renaming, copying, or deleting files on the server.
• Reading, writing, or appending to text files on the server.
The required attributes depend on the ACTION specified. For example, if
ACTION="WRITE", ColdFusion expects the attributes associated with writing a text
file.
Note Consider the security and logical structure of directories on the server
before allowing users access to them.
Uploading Files
File uploading requires that you create two files:
• An HTML form to enter file upload information
• An action page containing the file upload code
To create an HTML file to specify file upload information:
1. Create a new file in Studio.
2. Modify the file so that it appears as follows:
<HTML>
<HEAD>
<TITLE>Specify File to Upload</TITLE>
</HEAD>
<BODY>
<H2>Specify File to Upload</H2>
<FORM ACTION="uploadfileaction.cfm"
4 ENCTYPE="multipart/form-data"
METHOD="post">
<P>Enter the complete path and filename of the file to upload:
<INPUT TYPE="file"
NAME="FiletoUpload"
SIZE="45">
</P>
<INPUT TYPE="submit"
VALUE"Upload">
</FORM>
</BODY>
</HTML>
3. Save the file as uploadfileform.cfm in myapps under the Web root directory.
