It seems the problem is you send the form request to welcome do upload  and call the Welcome  do upload   method in another one by  this- gt do upload     Hence when you call the  this- gt do upload    within your second method  the   FILES array would be empty   And that s why var dump  data  upload data     returns NULL   If you want to upload the file from welcome second method  send the form request to the welcome second method where you call  this- gt do upload      Then change the form helper function  within the View  as follows1      Change the  second method  to your method name echo form open multipart  welcome second method        File Uploading with CodeIgniter  CodeIgniter has documented the Uploading process very well  by using the File Uploading library    You could take a look at the sample code in the user guide  And also  in order to get a better understanding of the uploading configs  Check the Config items Explanation section at the end of the manual page   Also there are couple of articles samples about the file uploading in CodeIgniter  you might want to consider    http   code tutsplus com tutorials how-to-upload-files-with-codeigniter-and-ajax--net-21684 http   runnable com UhIc93EfFJEMAADX how-to-upload-file-in-codeigniter http   jamshidhashimi com image-upload-with-codeigniter-2  http   code tutsplus com tutorials how-to-upload-files-with-codeigniter-and-ajax--net-21684 http   hashem ir CodeIgniter libraries file uploading html  CodeIgniter 3 0-dev User Guide    Just as a side-note  Make sure that you ve loaded the url and form helper functions before using the CodeIgniter sample code      Load the helper files within the Controller  this- gt load- gt helper  form     this- gt load- gt helper  url         1  The form must be  multipart  type for file uploading  Hence you should use form open multipart   helper function which returns   lt form method  post  action  controller method  enctype  multipart form-data    gt
