It sounds like a fairly common problem. You probably want to check the entry in your PHP.INI file:
register_globals = 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 = ON") ---------------
HTML:
<input type="text" name="testvariable" value="50">
PHP:
Echo "Value of testvariable is: $testvariable";
Output: Value of testvariable is: 50
------------- After Reinstall (assuming "register_globals = OFF") ----------
HTML:
<input type="text" name="testvariable" value="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 = OFF") ----------
HTML:
<input type="text" name="testvariable" value="50">
PHP:
$testvariable = $_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.
