Storing Form Data as a Session Variable

Question

So I was wondering if it would be possible to store data coming in from a form as a session variable    Heres what I have so far  but I don t know what to put for the Form Action   Thanks for looking    lt strong gt Test Form lt  strong gt   lt form action    method post  gt       lt input type  text  name  picturenum   gt       lt input type  submit  name  Submit  value  Submit     gt   lt  form gt    lt        if  isset   POST  Submit                  session  picturenum       POST  picturenum             gt     lt strong gt  lt   echo   session  picturenum     gt  lt  strong gt

That s perfectly fine and will work  But to use sessions you have to put session start    on the first line of the php code  So basically   lt  php session start       rest of stuff    gt

To use session variables  it s necessary to start the session by using  the session start function  this will allow you to store your data in the global variable   SESSION in a productive way  so your code will finally look like this    lt strong gt Test Form lt  strong gt   lt form action  quot  quot  method quot post quot  gt   lt input type  quot text quot  name  quot picturenum quot   gt   lt input type  quot submit quot  name  quot Submit quot  value  quot Submit  quot    gt   lt  form gt    lt  php        starting the session  session start       if  isset   POST  Submit           SESSION  picturenum       POST  picturenum          gt     lt strong gt  lt  php echo   SESSION  picturenum     gt  lt  strong gt   to make it easy to use and to avoid forgetting it again  you can create a session file php which you will want to be included in all your codes and will start the session for you  session start php   lt  php    session start       gt    and then include it wherever you like     lt strong gt Test Form lt  strong gt   lt form action  quot  quot  method quot post quot  gt   lt input type  quot text quot  name  quot picturenum quot   gt   lt input type  quot submit quot  name  quot Submit quot  value  quot Submit  quot    gt   lt  form gt    lt  php        including the session file  require once  quot session start php quot       if  isset   POST  Submit           SESSION  picturenum       POST  picturenum          gt    that way it is more portable and easy to maintain in the future  other remarks  if you are using Apache version 2 or newer  be careful  instead of  lt   to open php s tags  use  lt  php  otherwise your code will not be interpreted  variables names in php are case-sensitive  instead of write   session  write   SESSION in capital letters   good work

You can solve this problem using this code   if  empty   GET  variable from which you get          SESSION  something      GET  variable from which you get        So you get the variable from a GET form  you will store in the   SESSION  whatever   variable just once when   GET  variable from which you get  is set and if it is empty   SESSION  something   will store the old parameter

Yes this is possible  kizzie is correct with the session start    having to go first   another observation I made is that you need to filter your form data using   strip tags  value     and or  stripslashes  value
