All Posted files will be come in   FILES variable  for use codeigniter upload library we need to give field name that we are using in for upload  by default it will be  userfile    so we get all posted file and create another files array that create our own name for each files  and give this name to codeigniter library do upload function   if  empty   FILES         j   1                       foreach   FILES as  filekey  gt  fileattachments           foreach  fileattachments as  key  gt  val               if is array  val                     i   1                  foreach  val as  v                        field name    multiple    filekey      i                        FILES  field name   key     v                       i                                      else                   field name    single    filekey      j                    FILES  field name     fileattachments                   j                    break                                                            Unset the useless one          unset   FILES  filekey              foreach   FILES as  field name   gt   file           if isset  file  error     amp  amp   file  error    0                config  upload path      upload path                config  allowed types      allowed types                config  max size     100               config  max width     1024               config  max height     768               this- gt load- gt library  upload    config                this- gt upload- gt initialize  config                if      this- gt upload- gt do upload  field name                     error   array  error    gt   this- gt upload- gt display errors                     echo  Error Message       error  error                 else                   data    this- gt upload- gt data                    echo  Uploaded FileName      data  file name                       Code for insert into database

You should use this library for multi upload in CI https   github com stvnthomas CodeIgniter-Multi-Upload  Installation Simply copy the MY Upload php file to your applications library directory   Use  function test up in controller  public function test up    if  this- gt input- gt post  submit          path      public test upload         this- gt load- gt library  upload         this- gt upload- gt initialize array           upload path   gt  path           allowed types   gt                 if  this- gt upload- gt do multi upload  myfile             echo   lt pre gt            print r  this- gt upload- gt get multi upload data             echo   lt  pre gt           else       this- gt load- gt view  test upload view           upload view php in applications view test folder   lt form action    method  post  enctype  multipart form-data  gt   lt input type  file  name  myfile    id  myfile  multiple gt   lt input type  submit  name  submit  id  submit  value  submit   gt

Change   FILES to new vars and loop them         foreach   FILES  files   as  key  gt  val                         i   1              foreach  val as  v                                 field name    file    i                    FILES  field name   key     v                   i                                          Unset the useless one            unset   FILES  files                 Put each errors and upload data to an array          error   array             success   array                main action to upload each file         foreach   FILES as  field name   gt   file                        if      this- gt upload- gt do upload  field name                                 echo   failed                 else                  echo   success

Try this code  It s working fine for me You must initialize each time the library     function do upload                 foreach    FILES as  index   gt   value                        if   value  name                                         this- gt load- gt library  upload                     this- gt upload- gt initialize  this- gt set upload options                        upload the image                 if      this- gt upload- gt do upload  index                                          error  upload error      this- gt upload- gt display errors  quot  lt span class  error  gt  quot    quot  lt  span gt  quot                                               load the view and the layout                      this- gt load- gt view  pages uploadform    error                        return FALSE                                    else                                                              data  key    array  upload data    gt   this- gt upload- gt data                            this- gt load- gt view  pages uploadsuccess    data  key                                                                   private function set upload options                      upload an image options          config   array             config  upload path      your upload path            config  allowed types      gif jpg png                    return  config         Further edit I have found the way you must upload your files with one unique input box  CodeIgniter doesn t support multiple files  Using the do upload   in a foreach won t be different than using it outside  You will need to deal with it without the help of CodeIgniter  Here s an example https   github com woxxy FoOlSlide blob master application controllers admin series php L331-370 https   stackoverflow com a 9846065 1171049  This is that  said you in the commments
