Codeigniter this- input- post empty while POST is working correctly

Question

On a codeigniter installation  I am trying to use the inbuilt  this- gt input- gt post  some data   function  however  this- gt input- gt post   is an empty array   A print r   POST  gives all the variables fully and correctly   According to the codeigniter docs  The input class  is initialized automatically by the system so there is no need to do it manually   leaving me wondering what else I m meant to do   Any thoughts on how I should try to get this working   Thanks

To use  this- gt input- gt post    initialize the form helper  You could do that by default in config

Change your form action   From this    lt form method  post  action   lt   base url    gt yourprocess  gt    Into this    lt form method  post  action   lt   base url    gt index php yourprocess  gt    Basically  you just need to add  index php  after your base url        action  http   www yourdomain com index php yourprocess

There s a few things you can look for help solve this    Has anything changed or been extended in the core CodeIgniter files  Check that system core Input php is an original copy and the contents of application library and application core for additional files Do the other input methods work  What is the result of this when run beside your print r call   echo  this- gt input- gt user agent    What data is output from print r  Look in application config config php for the line  config  global xss filtering    Is this set to TRUE or FALSE  If TRUE maybe the cross site scripting filter has a problem with the data you re posting  this is unlikely I think

The problem is that  this- gt input- gt post   does not support getting all POST data  only specific data  for example  this- gt input- gt post  my post var    This is why var dump  this- gt input- gt post     is empty    A few solutions  stick to   POST for retrieving all POST data  or assign variables from each POST item that you need  for example       variables will be false if not post data exists  var 1    this- gt input- gt post  my post var 1     var 2    this- gt input- gt post  my post var 2     var 3    this- gt input- gt post  my post var 3      However  since the above code is not very DRY  I like to do the following    if  empty   POST             get all post data in one nice array     foreach    POST as  key   gt   value                  insert  key     value          else          user hasen t submitted anything yet

You can check  if your view looks something like this  correct     lt form method  post  action   controller submit   gt    vs  doesn t work     lt form method  post  action   controller submit  gt    Second one here is incorrect  because it redirects without carrying over post variables   Explanation   When url doesn t have slash in the end  it means that this points to a file   Now  when web server looks up the file  it sees  that this is really a directory and sends a redirect to the browser with a slash in the end   Browser makes new query to the new URL with slash  but doesn t post the form contents  That s where the form contents are lost

You are missing the parent constructor  When your controller is loaded you must Call the parent CI Controller class constructor in your controller constructor
