Dump the global variable to find out what you have in the page scope   var dump  GLOBALS     This will tell you the  what  and  where  regarding the data on your page

A few thing you could do    Make sure that the  action  attribute on your form leads to the correct destination  Try using   REQUEST   instead of   POST  see if there is any change   Optional  Try including both a  name  and an  id  attribute e g         lt input type  text  name  firstname  id  firstname  gt     If you are in a Linux environment  check that you have both Read Write permissions to the file    In addition  this link might also help   EDIT   You could also substitute    lt code gt if isset   POST  submit      lt  code gt    with this    lt code gt if   SERVER  REQUEST METHOD       POST     lt  code gt    This is always the best way of checking whether or not a form has been submitted

try doing var dump   GLOBALS    A potential cause could be that there is a script running before yours which unsets the global variables  Such as   unset   REQUEST     or even   unset  GLOBALS     This could be done via the auto prepend file option in the php ini configuration

I had something similar this evening which was driving me batty  Submitting a form was giving me the values in   REQUEST but not in   POST   Eventually I noticed that there were actually two requests going through on the network tab in firebug  first a POST with a 301 response  then a GET with a 200 response   Hunting about the interwebs it sounded like most people thought this was to do with mod rewrite causing the POST request to redirect and thus change to a GET   In my case it wasn t mod rewrite to blame  it was something far simpler    my URL for the POST also contained a GET query string which was starting without a trailing slash on the URL  It was this causing apache to redirect   Spot the difference      Bad    http   blah de blah my path key value amp otherkey othervalue  Good   http   blah de blah my path  key value amp otherkey othervalue  The bottom one doesn t cause a redirect and gives me   POST

Try get instead for test reasons   lt form action    name test  method  GET  gt     lt input type  text  name  firstname    gt     lt input type  submit  name  submit  value  Submit    gt   lt  form gt    and  if isset   GET        echo   GET  name       lt br gt        echo   GET  firstname
