session problem.. TRULLY WEIRD..

[Tea_J]

Hey guys

i am making a sign-up form..

to cut the story short...

Thes signup form sends all the variables via POST to a "register.php" script..

the register.php script sets several session variables based on the user inputs on the first form..

The weird thing is, the whole script works perfectly, untill i have the following lines

  $_SESSION['pass1'] = $pass1;
  $_SESSION['pass2'] = $pass2;
   $_SESSION["nameM"] = $nameM;
  $_SESSION["nameP"] = $nameP;
  $_SESSION["onsiteS"] = $nameS;

when i have those lines in my script i get a "The page cannot be displayed" error as if my register.php script isnt present..

I did some playing around..after HOURS of trying to figure out wha the heck is wrong, I noticed some patterns..

i noticed that my script works if:

1) I set 3 of the above session variables only and remove 2

eg:

  $_SESSION['pass1'] = $pass1;
  $_SESSION['pass2'] = $pass2;
  $_SESSION["nameM"] = $nameM;

If I include a FOURTH one.. page will not be found..

2) Adding the fourth line gives a page display error:
eg

  $_SESSION['pass1'] = $pass1;
  $_SESSION['pass2'] = $pass2;
  $_SESSION["nameM"] = $nameM;
  $_SESSION["nameP"] = $nameP;

BUT IF I SLIGHTLY change the fourth line to something like:

  $_SESSION['pass1'] = $pass1;
  $_SESSION['pass2'] = $pass2;
  $_SESSION["nameM"] = $nameM;
  $_SESSION["nameMP"] = $nameP;

the script will work! any SLIGHT modification from
nameM
to
nameMP or name21313 or nam

it will work..

3) I also noticed that enclosing the source variables in quotes can make things work again..

eg

  $_SESSION['pass1'] = "$pass1";
  $_SESSION['pass2'] = "$pass2";
  $_SESSION["nameM"] = "$nameM";
  $_SESSION["nameMP"] = "$nameP";

Other things i've noticed..

I tested my script on my online server and there seems to be no problem.. i did notice that the online server has

register_globals = On

while i have mine turned OFF

.. ofcourse it's advisable to keep register_globals OFF.. and well, I DONT SEE WHY the PHP is behaving this way whether global variables are on or off...

any ideas??

something to do with the double quotes on the session name maybe :queasy:

  $_SESSION['pass2'] = $pass2;
   $_SESSION["nameM"] = $nameM; 

i have no idea :p :p

i have no idea

lolz

nice try buddy.. hehe

but that's just me experimenting and trying desperately to figure out "something"...

[Tea_J]

still have this problem..

[halojoy]

it has to do with globals = ON
at least this is what I think

if you would use different variable names in every line it can work
$_SESSION ['name1a'] = $name1b;
should work

My thought is that setting BOTH same
will be equal to:
$name = $name;
and that does nothing

[Tea_J]

yup.. you are right.. i had to turn on my global_variables in php.ini..

scripts work now..

however, i still dont know why it would cause a "The page cannot be displayed" error.....

hmm... thanks anyway.

You DONT! want register_globals on its a security issue just trust me i cannot remember were i read it but yea.

[halojoy]

It is at http://php.net
we can read about Security and register_globals = ON
For example:
http://php.net/security.globals

[Tea_J]

yup, i am aware of it being a security issue.. but i have no choice.. besides, it's not that big of an issue really.. if you just code your scripts properly it's fine..

also, even though registered globals are on, i still declare the internal variables via expected method (POST or GET).. so any illegally passed variables are not entertained in my scripts.
