onFileUploadExecuteCallBackFunction

calls a local function when a file is uploaded

void onFileUploadExecuteCallBackFunction ( String functionName )

use this function when you want to apply certain logic (or display a certain message) when a file is uploaded. Use of this function is similiar in a way to a java interface: you must define a function with the name specifed in the function call.

This function must take ONE parameter (an array). The indexes of this array are as follows:

id (the id of the row for which the file was uploaded)

(your primary key) (the id of the row for which the file was uploaded)

field (the fieldname to which the file was uploaded [the filename was placed in this field: see setFileUpload])

fileName (the name of the file) [may have been renamed]

fileSize (the filesize of the file)

fldType (the filetype of the file)

Details

Requires	setFileUpload, your callback function

  $id         = $array[id];  //this will always be the value
  $id         = $array[pkID]; //same as above IF the pk is pkID
  $fileName   = $array[fileName];
  $fileSize   = $array[fileSize];
  $fileType   = $array[fldType];
  
  if ($fileName != ''){
    $success = qr("UPDATE tblDemo SET fldFilesize = '$fileSize'
                                  WHERE pkDemoID = $id");
