$_POST and $_GET

[NeedHelp]

While working on one server and connecting to a URL such as myscript.php?var=this I can use code like this:

PHP Code:

<?
echo $var; // Echos this
?>

and it works fine. However, on another server if I put the same code and same URL syntax I get nothing. What is wrong on the second server?

nothing is wrong with the second server other than it is more secure with its registered globals. If you have access to the php.ini find this line

register_globals =

and change it to either on or off depending on what it is set as now...


But either way this should work:

PHP Code:

<?
echo $_GET['var']; // Echos this
?>

I don't have access to the php.ini.
So there is no way to make those variables global? I have to use $_GET['var']? Is post the same $_POST['var']?

[John]

its not a matter of global variables. gloval variables come into effect when you are working with seperate functions.

But yes you have to use $_GET['variable'] and $_POST['variable']. What i do a lot of times when im programing is right after the <?php set $_GET['variable'] equal to the reular variable so its easier to read.

PHP Code:

<?php
$variable = $_GET['variable'];

//your code

?>

You can always extract the data as well. Do this at the top of your scripts

PHP Code:

if(!empty($_GET)) extract($_GET);
if(!empty($_POST)) extract($_POST); 


Works as if register_globals was set to ON

PHP Code:

<?php
    $var = $_REQUEST['var']
?>

not a good choice
