Im new to PHP and I face a problem of value passing. 🙁

Im using Apache 2.0 with PHP4

Please look at following coding :

<html>
<body>

<?php

if ($id) {

if ($id=="1") { Printf("Green Color<br>"); }

else { Printf("Yellow Color<br>"); }

} else

{
printf("<a href=\"%s?id=%s\">%s</a><br>\n",$PHP_SELF,"1","Select Color 1");

printf("<a href=\"%s?id=%s\">%s</a><br>\n",$PHP_SELF,"2","Select Color 2");
}

?>

</body>
</html>

Save as color.php

When open it from browser IE 6 using Address http://localhost/color.php

it shows following result with link :

Select Color 1
Select Color 2

When I click on "Select Color 1"

Address become ---> http://localhost/color.php?id=1

But the browser still showing me following result :

Select Color 1
Select Color 2

It should show "Green Color"
Meaning browser unable to get the value for $id
What could be the problem ? Can anyone help ? 😕

Most likely register_globals is turned off. This means that if the "id" key is in the URL, you can't just reference it with $id. Change all your references to $id to $_GET['id'] instead, and it should work.

Otherwise, your code looks fine.

he's right, do this..

<html>
<body>

<?php
$id =  $_GET['id']    //<-- thats all thats changed
if ($id) {

if ($id=="1") { Printf("Green Color<br>"); }

else { Printf("Yellow Color<br>"); }

} else

{
printf("<a href=\"%s?id=%s\">%s</a><br>\n",$PHP_SELF,"1","Select Color 1");

printf("<a href=\"%s?id=%s\">%s</a><br>\n",$PHP_SELF,"2","Select Color 2");
}

?>

</body>
</html>

I've been using this method for a while:

$var = isset($_REQUEST["var"]) ? $_REQUEST["var"] : "default value";
