A problem with an installation program

thebay

IN the following piece of code, when I click "next " I should go to installation step by step, why there is no response when I test it?

This program is working well on unix, do I need modify something when use it on winxp????

it has not to do with the OS.
You have register_globals disabled in your php.ini, try enabling it. You can also read in php.net about the "new" superglobals $GET, $POST and company and why is safer to disable register_globals anyway.

I want pass the value of $step whenever I click the "next step"
by this code :
$step_="<a href=install.php?step=1>next step here</a>";

but I set breakpints and found it won't change. Why?
By the way I have change "rigistered_global" as turn on in
php.ini.

if(file_exists("config.php")){echo"finish";exit;}

$correct='<font color=blue>OK</font>';
$incorrect='<font color=red>not pass</font>';
$check=1;

if(empty($step)) $step=0;
if($step==0){

echo $step; // yes , $step is 0;

$body="well come you<br> ;
$step_="<a href=install.php?step=1>next step here</a>";

}

echo $step; // I checked here, why $step is still 0 !!!!!!!

if($step==1){

echo
$body="check if all program here<br><br><br>";
echo $body;
