- Parameters for FTP upload -

Here is the list and the meaning of all JFileUpload parameters for FTP upload. You will also find HTML/JavaScript sample for Applet definition. Notice that there are two types of parameter: regular and extra. "dummy=test" regular parameter is setup through <PARAM NAME="dummy" VALUE="test">. dummy=test extra parameter number five is setup through <PARAM NAME"param5" VALUE="dummy"> and <PARAM NAME"value5" VALUE="test">.

JFileUpload regular parameters
Parameters Description and sample Mandatory
url FTP server URL that will process the upload.
For instance, ftp://ftp.mycompany.com
yes
mode This parameter allows to select transport protocol. For FTP upload it must be "ftp". yes
maxsize This parameter allows to limit upload size (in bytes). For instance, to avoid end-user to send more than 1MB file, use maxsize=1048576. Default maxsize is -1. It means unlimited upload size. Note that 1MB=1024*1024=1048576 bytes. no
maxfiles This parameter allows to limit number of files to upload. Default maxfiles is -1. It means unlimited files.
no
whitelist This parameter allows to filter filenames to upload (*.doc, *.exe,*.gif,*.pdf ...). For instance, to allow end-user to upload microsoft excel files only, use whitelist="*.xls". For both gif and jpeg use whitelist="*.gif,*.jpg,*.jpeg".
no
blacklist This parameter allows to forbid filenames to upload (*.exe, *.zip,*.mp3 ...). For instance, to disallow end-user to upload microsoft executable files, use blacklist="*.exe". Note that if you use blacklist then you cannot use whitelist parameter.
no
policy This parameter allows to modify JFileUpload behavior when a file to upload does not match to whitelist or maxsize. Default value is "abort", it means that upload won't proceed. "ignore" value means upload will proceed and unmatching files will be ignored.
no
folderdepth This parameter allows to set a max depth for directories and subdirectories uploads. Default is 0, it means to not recurse subdirectories. -1 means unlimited.
no
resume This parameter allows to resume broken uploads. Values could be "true" or "false". Default is false. An upload is considered broken if remote file already exists and size < local file size.
See FAQ to learn how it works.
no
overwrite This parameter allows to define overwrite policy for duplicate file on remote server. Values could be :
"true": Allow overwrite.
"false": Return an error message for duplicate uploads.
"indexrename": Rename duplicate upload such as file_1.zip
"timerename": Rename duplicate upload such as file_mstime.zip
Default value is true. See FAQ to learn how it works.
no
hiddenfile This parameter allows to "accept" or "deny" hidden files for upload. Default value is "accept".
no
template This parameter allows to rename files to upload with a given template. Value could be any combination of :
  ":filename:" => Selected filename.
  ":name:" => Selected name.
  ":shortname:" => Selected short name.
  ":extension:" => Selected extension.
  ":timestamp:" => Unix-like (epoch) timestamp.
  ":identifier:" => Auto increment integer starting at zero
  or value defined by identifierinit parameter.
  For instance, 
  template="test_:timestamp:_:name::extension:"
Value could be a regular expression followed by a string that will replace characters matching to the regular expression:
  ":regex=YourRegExpHere:ReplaceString:"
  For instance, if you want to replace all non ASCII characters   and punctuation by "_" then value of template will be:
  ":regex=[^a-zA-Z0-9_\\-\\.]:_:".;
If you need to apply template to folders in addition to files then add templatescope="path" parameter.
no
ziponfly This parameter allows to zip file on-fly before uploading. It reduces bandwidth usage but it could affect client performance because of compression process.
Values could be :
"true" or "zip" => ZIP compression
"gzip" => GZIP compression.
".zip" or ".gz" extension will be appended to uploaded filename. Default value is "false". Learn more in FAQ.
For overall (one ZIP archive) compression, see tutorial.
no
zipignorelist When ziponfly is enabled, this parameter allows to setup filenames to not zip. For instance, zipgnorelist="*.zip,*gif". no
zipmaxsize This parameter allows to limit upload size (in bytes) of compressed file. For instance, to avoid end-user to send more than 1MB file, use zipmaxsize=1048576. Default zipmaxsize is -1. It means unlimited. no
startdir This parameter allows to setup a local directory, instead of user's home, when using file browser (e.g. startdir="c:/tmp")
no
authentication Setup authentication="auto" if you want to prompt end-user for FTP login/password instead of passing username and password in applet parameters. Default value is "disabled".
no
forward This parameter allows to redirect to another URL once upload is completed. You could select the target frame through forwardtarget parameter (see below).
For instance, forward="http://yourserver.com/redirect.php"
no
forwardtarget When forward parameter is enabled, this parameter allows to redirect URL to a given browser frame. Use _blank for new window.
no
forwardparameters When this parameter is set to true, JFileUpload appends uploaded filenames to redirect URL. For instance, "?filename1=foo1.txt&filename2=foo2.zip ..."
no
post This parameter allows to send HTTP POST request once upload is completed. See FAQ to learn how it works.
For instance, post="http://yourserver.com/process.php"
no
postparameters This parameter allows to pass filenames uploaded in POST request above.
"true" means "filename1=foo1.txt&filename2=foo2.zip..."
"long" means "filename1=/home/usr1/foo1.txt&filename2=..."
"extra" is same as long with filesize, last modified timestamp and extra parameters. See tutorial to learn more.
no
retry This parameter allows to retry current upload when underlying socket fails (bad networks, connection timeout). For instance, to enable 3 retry attempts => retry="3" no
retrydelay This parameter allows to setup delay in seconds between each retry attempts. Default is 2 seconds. no
preferences Use preferences="true" to enable persistent preferences such as last directory opened. no
timeout This advanced parameter allows to modify underlying socket timeout in milliseconds. no
socksproxyhost This advanced parameter allows to setup SOCKS proxy host.
no
socksproxyport This parameter allows to setup SOCKS proxy port. no
resources This advanced parameter allows to select a custom properties file including all resources (messages, errors, menu, items, colors) to be displayed. See internationalization section in FAQ to learn more. no
localeresources This advanced parameter allows to load resources based end-user locale/country code. Default is true. no
verbosemode This advanced parameter allows enabling applet traces for debugging purposes:
"debug" => Debug traces are displayed in Java console.
no

 auth_tls : AUTH TLS command is sent before SSL handshake.

JFileUpload HTML and JavaScript declaration sample
Below the code you need to copy/paste in your HTML source to use JFileUpload applet:
<!-- JFileUpload Applet : Begin copy/paste -->
<script src="applet_ftp.js"></script>
<!-- JFileUpload Applet : End copy/paste -->

Copy applet_ftp.js javascript file in the same folder as your HTML file. Setup parameters (according to table above) in blue. Notice that all parameters need to be setup twice (it allows cross-browsers support).
