cffile upload test source code
Just a quick example here of a script that helps you to understand file uploads and a few other things. Look in the documentation for more tricks.
It presents you with a form to get a file on your local machine and click submit to upload it to whatever directory you want it stored on your server.
Then it will show you the temp directory it stored it to before moving it to the target directory. It will also show you a dump of the file upload result and the directory where you're uploading files to.
You can set file size limits and file extension type limits. It will also output a list of the uploaded files and compare it to a predetermined date and time.
<cfparam name="fileDirectory" default="c:\path\to\your\directory\"/>
<cfparam name="form.file" default=""/>
<cfparam name="fileSuccess" default="Error"/>
<cfparam name="fileSizeLimitKB" default="500"/>
<cfparam name="fileExtAllowed" default="doc,txt,gif,jpg,jpeg,pdf,png,tif,tiff,mpg,mpeg,mp3,wav,zip,rar,xls,csv"/>
<cfparam name="fileDateCompare" default="#dateAdd('n',-2,now())#"/>
<cfif form.file neq "">
<cfoutput>Uploaded temp location: #form.file#<br /></cfoutput>
<!--- calculate file size limit from param --->
<cfset sizelimit = fileSizeLimitKB * 1000>
<!--- upload file and get results --->

<!--- check if file upload save was successful --->
<cfif uploadResult.fileWasSaved>
<!--- set param of uploaded file path in case of delete --->
<cfset newFile = uploadResult.serverDirectory & "/" & uploadResult.serverFile>
<!--- check for size and unsafe file extensions --->
