you can use call back function   like this      this- gt form validation- gt set rules  userfile    Document    callback file selected test         if   this- gt form validation- gt run      FALSE               error            else                success                 function file selected test          this- gt form validation- gt set message  file selected test    Please select file         if  empty   FILES  userfile    name                   return false           else              return true

you can solve it by overriding the Run function of CI Form Validation  copy this function in a class which extends CI Form Validation    This function will override the parent class function   Here i added only a extra check which can handle file also          Run the Validator       This function does all the work         access  public     return  bool     function run  group                Do we even have any data to process   Mm      if  count   POST     0            return FALSE                Does the  field data array containing the validation rules exist         If not  we look to see if they were assigned via a config file     if  count  this- gt  field data     0               No validation rules   We re done            if  count  this- gt  config rules     0                return FALSE                        Is there a validation rule for the particular URI being accessed           uri     group          trim  this- gt CI- gt uri- gt ruri string            group           if   uri       AND isset  this- gt  config rules  uri                   this- gt set rules  this- gt  config rules  uri              else                this- gt set rules  this- gt  config rules                         We re we able to set the rules correctly          if  count  this- gt  field data     0                log message  debug    Unable to find validation rules                return FALSE                          Load the language file containing error messages      this- gt CI- gt lang- gt load  form validation            Cycle through the rules for each field  match the        corresponding   POST or   FILES item and test for errors     foreach   this- gt  field data as  field   gt   row               Fetch the data from the corresponding   POST or   FILES array and cache it in the  field data array             Depending on whether the field name is an array or a string will determine where we get it from           if   row  is array      TRUE                 if  isset   FILES  field                       this- gt  field data  field   postdata      this- gt  reduce array   FILES   row  keys                   else                    this- gt  field data  field   postdata      this- gt  reduce array   POST   row  keys                             else               if  isset   POST  field   AND   POST  field                            this- gt  field data  field   postdata       POST  field                 else if  isset   FILES  field   AND   FILES  field                            this- gt  field data  field   postdata       FILES  field                                     this- gt  execute  row  explode       row  rules      this- gt  field data  field   postdata                   Did we end up with any errors       total errors   count  this- gt  error array        if   total errors  gt  0             this- gt  safe form data   TRUE                Now we need to re-set the POST data with the new  processed data      this- gt  reset post array            No errors  validation passes      if   total errors    0            return TRUE                Validation fails     return FALSE

CodeIgniter file upload optionally    works perfectly           ---------- controller ---------  function file       this- gt load- gt view  includes template    data      function valid file       this- gt form validation- gt set rules  userfile    File    trim xss clean      if   this- gt form validation- gt run    FALSE           this- gt file        else       config  upload path          documents       config  allowed types      gif jpg png docx doc txt rtf      config  max size           1000      config  max width          1024      config  max height         768       this- gt load- gt library  upload    config      if     this- gt upload- gt do upload  userfile  FALSE            this- gt form validation- gt set message  checkdoc    data  error      this- gt upload- gt display errors          if   FILES  userfile    error      4                return false               else         return true          i just use this lines which makes it optionally    if   FILES  userfile    error      4     return false       FILES  userfile    error      4 is for file required to upload    you can make it unnecessary by using   FILES  userfile    error      4  then it will pass this error for file required and works great with other types of errors if any by using return false   hope it works for u
