passing vars

Anon

I've just installed Apache/PHP/MySQL

Everything seems to work fine, but when i try to pass a var by url of form, then it goes wrong.

The var in the script never gets the assigned value!! for example
http://localhost/add.php3?id=1
or
<form.... action="add.php3">
.....name="id" value="1"..
Submit

Can it be a problem with Apache.. Or PHP

I really don't now what the problem is!
Everything works except the passing!!!!

Try echoing and see if you get the var to pass..

So you have the form:

name="id" value="i"

the add.php file put in

echo $id;

See if anything comes out.

Try creating the following file:

<?php echo $id ?>

and call it by:

http://www.server.com/file.php?id=2

You should get a webpage with "2" as the content. If not then you have a problem with Apache and/or PHP. If you get the two then the problem is your code, and not the server.

I've tried this yet.

I tried it again now, and notting apears when i type
http://localhost/test.php3?id=2

where test.php3 is

<?php echo "$id"?>

Maybe the problem lies here:
I've loaded de module php4apache2.dll in de httpd.conf file instead of php4apache.dll. Because when I loaded php4apache.dll the following error-message occured when trying to run apache:
Syntax error on line 496 in httpd.conf...
.. Cannot load c:/php/sapi/php4apache.dll into server: The specified module could not be found.
With the php4apache2.dll there was no problem!

Hey me again:

This appears when echoing phpinfo():

SERVER["REMOTE_PORT"] 3711

SERVER["GATEWAY_INTERFACE"] CGI/1.1

SERVER["SERVER_PROTOCOL"] HTTP/1.1

SERVER["REQUEST_METHOD"] GET

SERVER["QUERY_STRING"] id=2

SERVER["REQUEST_URI"] /test.php3?id=2

SERVER["SCRIPT_NAME"] /test.php3

SERVER["PHP_SELF"] /test.php3

_SERVER["argv"] Array
(
[0] => id=2
)

_SERVER["argc"] 1

Still echoing $id puts nothing on the screen!!

HELP

I've found the problem!
This is what i found:

If you have the following URL:

http://www.example.com/foo.php?fruit=apple

The variable $fruit will automatically exist if the PHP directive
register_globals = on. As of PHP 4.2.0, the default for this
directive is off and since PHP 4.1.0 it's been encouraged to not
rely on the behavior. There are many other methods:

print $HTTP_GET_VARS['fruit']; // apple
print $_GET['fruit']; // apple

import_request_variables('g', 'g_');
print $g_fruit; // apple

extract($HTTP_GET_VARS);
print $fruit; // apple

$HTTP_GET_VARS has been around forever, $_GET is a superglobal and
it along with import_request_variables() became available in PHP 4.1.0,
and extract() is another possability.

This topic has been discussed in the PHP mailing lists a few times
