Description

Displays a dialog for uploading multiple files from the user's system. The enhanced dialog includes the following features:

You can specify the maximum number of files and the maximum file size for the upload.
A progress bar to visually indicate the overall progress of the file upload task, and another progress bar to indicate the upload progress of each individual file.
A success or failure message appears for each file upload and the overall upload task.
At any point during the upload task, you can cancel the upload.

ColdFusion 9: Added this tag.

Attributes

Attribute	Req/Opt	Default	Description
addbuttonlabel	Optional	Add Files	Label of the Add button.
align	Optional	left	Specifies the default alignment. The following values are valid: center left right
bgcolor	Optional		The background color for the file upload control. A hexadecimal value without "#" prefixed or a recognized color name, for example red.
clearbuttonlabel	Optional	Clear All	Label of the Clear button
deletebuttonlabel	Optional	Delete	Label of the Delete button
extensionfilter	Optional	none	Use this attribute to specify the type of file that you will allow to be uploaded. For example, to let only image files to be uploaded, you can specify file extensions such as .jpg, .jpeg, or .png. If set to none, files are uploaded without any extension filter.
height	Optional	300	Height of the file upload control, in pixels.
hideUploadButton	Optional	false	A Boolean value that specifies if the Upload button should appear in the file upload dialog: true false
maxfileselect	Optional		The maximum number of files allowed for upload.
maxuploadsize	Optional	10MB	The maximum file size, in Megabytes, allowed for upload in an operation.ColdFusion throws an error if the value of the attribute maxuploadsize exceeds the throttle/ post data size settings specified in the ColdFusion Administrator.
name	Optional		Name of the file upload component.
onComplete	Optional		The JavaScript function to run when a file has finished uploading.By default, ColdFusion passes a JavaScript object as a parameter to this function with the following properties: STATUS - numeric value that is based on the HTTP status code MESSAGE - Passed or Failed FILENAME - Name of the file selected for upload You can also pass the JavaScript object by creating a struct with parameters "status" and "message" and call serializeJSON() on the JavaScript object.
onError	Optional		The JavaScript function to run if the uploading of a file fails. The error can be a network error or server-side error. By default, ColdFusion passes a JavaScript object as a parameter to this function with the following properties: STATUS - numeric value that is based on the HTTP status code MESSAGE - Passed or Failed FILENAME - Name of the file selected for upload You can also pass the JavaScript object by creating a struct with parameters "status" and "message" and call serializeJSON() on the JavaScript object.
onUploadComplete	Optional		The JavaScript function to run after uploading all the files.
progressbar	Optional	true	Whether to display a progress bar while the files upload: true false
stoponerror	Optional	true	Specifies whether to ignore the exceptions for this operation. true - Stops uploading and displays an appropriate error. false - Continues uploading and displays an appropriate error.
style	Optional		A CSS style specification that defines layout styles.
title	Optional		Title for the upload dialog.
uploadbuttonlabel	Optional	Upload	Label of the Upload button.
url	Optional		The URL to the server where the files are uploaded. The attribute is optional and it defaults to cgi.script_name.
width	Optional	420	Width of the file upload control, in pixels.
wmode	Optional	window	Specifies the absolute positioning and layering capabilities in your browser: window: Plays the media player in its own rectangular window on a web page opaque: Hides everything behind the media player on the web page transparent: Lets the background of the web page show through the transparent portions of the media player

Usage

Use this tag to create a SWF file-based file upload control that lets a user upload multiple files to a server. To upload files to the server, define a server-side template. The template that you define reads the upload request and uploads the selected files to the server.

Enhancements made in ColdFusion 9.0.1

In ColdFusion 9.0.1, the fileupload control passes the session information implicitly to the target page if session management is turned on either in Application.cfc or Application.cfm.Assume that fileupload control is defined without a URL attribute. In this case, if the user chooses to upload data using the upload button, the control comes back to the same page. Users can check for form.fieldnames to perform the upload as shown in the following example:Upload.cfm

</cfif>

<cfif isdefined("form.FIELDNAMES")> 
<cffile action = "upload" destination = "#ExpandPath('.')#" nameconflict="makeunique"> 
</cfif> 
<cffileupload name="myuploader">

In this case, url defaults to CGI.script_name.

To maintain sessions between the fileupload control and the URL, users must turn on session management. You can do this by setting the this.sessionmanagement=true in Application.cfc. The setting ensures that CFID and CFtoken are passed as part of the URL if Enable J2EE Session Variables (ColdFusion Administrator > Server Settings > Memory Variables) is not selected. If it is selected, then JsessionID is passed as part of the URL.

Supported Styles

The following are the supported styles:

Style	Description
headercolors	Format: color; colors of the band at the top of the DateChooser control. Specify two values, separated by a comma. For a solid band, use the same color for both values. The default value is ##E6EEEE,##FFFFFF.
textcolor	Color of text. Can be a hexadecimal value or a named color. For a hexadecimal value, use the form"##xxxxxx", where x = 0-9 or A-F; use two number signs or none.
titletextalign	Aligns the title text. The recognized values are left, right, and center. The default value is right.
titletextcolor	Color of the title text.
bgcolor	The background color for the file upload control. A hexadecimal value without "#" prefixed or a recognized color name, for example red.
rollovercolor	Displays values on mouse-over.

uploadfiles.cfm is given below:

<cffile action="upload" destination="#expandpath('./upload')#" nameconflict="makeunique"> <cfoutput>#serializeJSON({STATUS=200,MESSAGE='Passed'})#</cfoutput>

<cffile action="upload" destination="#expandpath('./upload')#" nameconflict="makeunique"> <cfoutput>#serializeJSON({STATUS=200,MESSAGE='Passed'})#</cfoutput>

This example sends user-specified files to the server-side template - uploadfiles.cfm. The template file that you define can use the "upload" or "uploadall" action defined in the cffile tag.

Note: The filefield attribute of the upload action is optional.

Use the destination attribute in the cffile tag to define the location to save the files. For the uploadfiles.cfm code, see cffile action = "uploadAll".
