If you provide a bit of your source code. It would be quicker to =
determine the problem.

Subject: [PHP-WIN] I've found the cause of the error but I cant fix it.

Hi all,
The problem is the GET and the POST method.
I've create a simple form and I pass my name on it, on the other hand, =
on the file referenced in the form, I put an echo with the variable, and =
it doesn't print it. (I use GET, on the link it shows it, but the =
variable is empty).

How can I fix it?

Best Regards,

Alex

If you're used to running on a system with register_globals turned ON =
then you might run into a snag with something like this since the GET =
and POST values aren't automatically assigned to the variables you're =
trying to echo.

You need to do:

$variablename =3D $_GET["variablename"];

Or...

$variablename =3D $_POST["variablename"];

Or..

$variablename =3D $_REQUEST["variablename"];

The last one (REQUEST) will populate the $variablename variable with =
either GET or POST data so can be used for either. I forget the order =
that it takes it though, I believe it essentially does:

If (isset($_POST["variablename"])) $variablename =3D =
$_POST["variablename"];
If (isset($_GET["variablename"])) $variablename =3D =
$_GET["variablename"];

(or vice versa)

So if both $_POST["variablename"] and $_GET["variablename"] are both =
set, then the data stored in the GET overwrites the POST data previously =
assigned to $variablename.

It IS possible to pass both POST and GET data at the same time:

<form action=3D"index.php?GETVARIABLE=3Dtestget" method=3D"POST">
<input type=3D"text" name=3D"POSTVARIABLE" value=3D"testpost">
</form>

Var_dump($_REQUEST) will have both GETVARIABLE and POSTVARIABLE values =
("testget" and "testpost" respectively) available where as $_GET only =
has the GETVARIABLE value ("testget") and $_POST only has the =
POSTVARIABLE value ("testpost")

I understands you well but the problem is a w

ago with a OS Win98 all the
pages funcioned very well, but when I install WinXP, and configure the
mysql, apache and php and I tested with the same pages I've used on W98 it's
not working.
Where is the configuring problem?

If you need some of the files like php.ini and httpd.conf, tell me and I'll
send you those files.

Thxs for helping me!!!

It sounds like a fairly common problem. You probably want to check the =
entry in your PHP.INI file:

register_globals =3D Off

You might have had it turned ON before in which case you wouldn't have =
to use $_POST or $_GET to get the values of the variables, they're =
automatically assigned to whatever the $_POST or $_GET variable name is.

For security reasons, you really should set it to OFF (as illustrated =
above). Sample code/example follows:

------------- Before Reinstall (assuming "register_globals =3D ON") =
---------------
HTML:
<input type=3D"text" name=3D"testvariable" value=3D"50">

PHP:
Echo "Value of testvariable is: $testvariable";
Output: Value of testvariable is: 50

------------- After Reinstall (assuming "register_globals =3D OFF") =
----------
HTML:
<input type=3D"text" name=3D"testvariable" value=3D"50">

PHP:
Echo "Value of testvariable is: $testvariable";
Output: Value of testvariable is:
(no value is present in $testvariable because it's not automatically =
assigned when "register_globals" is turned off)

------------- After Reinstall ("register_globals =3D OFF") ----------
HTML:
<input type=3D"text" name=3D"testvariable" value=3D"50">

PHP:
$testvariable =3D $_REQUEST["testvariable"];
Echo "Value of testvariable is: $testvariable";
Output: Value of testvariable is: 50
(no value is present in $testvariable because it's not automatically =
assigned when "register_globals" is turned off)

Try something like that.

What versions of PHP are/were you running? The newest versions install with
globals not automatically being registered by default as opposed to the
older versions that by default registered globals. Perhaps that is the
problem, that you have an older version on 98 where globals are
automatically registered so your POST variables are available but in the
newest version you've installed on XP doesn't do that by default.

Check the register_globals variable in your phpinfo() output. Is it on or
off?
